She has 7 gallons of gas after driving for 2 hours.
What is Subtraction?
Subtraction is a mathematical operation that involves finding the difference between two numbers or quantities. It is the inverse of addition, which means that it is the opposite process of adding numbers.
In subtraction, a number or quantity (called the subtrahend) is subtracted from another number or quantity (called the minuend), resulting in the difference. The symbol used for subtraction is "-" and the resulting value is called the remainder or difference.
Katie had 12 gallons of gas.
She used 2 1/2 gallons of gas each hour.
Now, She drove 2 hours.
So, gallon of gas use for 2 hours = 2 × 2 1/2
= 2 × 5/2
= 5 gallons of gas.
Now, Gallons of gas left after 2 hours
= total gallons of gas - Gallons used for 2 hours
= 12 - 5
= 7.
Hence, She is left with 7 (12-5) gallons of gas.

Therefore , the solution of the given problem of coordinates comes out to be , T's values are (15, 7).
Describe coordinate.
A coordinate system can be used to precisely find points or additional mathematical objects on such a space, including Euclidean space, by using one or more variables or coordinates. To find a point or item on a double plane, one uses coordinates, which are pairs of numbers. Two numbers called the y and x matrices are used to describe a point's location on a two-dimensional plane. a set of numbers used to identify specific locations. The number usually consists of two digits.
Here,
In other terms, the x-coordinate of T is 6 times the difference between t and 6, or:
=> T's x-coordinate is 6 plus (6 minus (-3)) = 15
We can use the fact that the line of reflection is just the perpendicular bisector of the section joining t and to determine the y-coordinate of T. T's separation from the line
=> x=6 is 6 - (-3) = 9,
which is also T's separation from the line x=6.
The y-coordinate of T is the same as the y-coordinate of t because the line of reflection is the perpendicular bisector of the section joining t and T, which is:
=>T has a y-coordinate of 7.
Consequently, T's values are (15, 7).

Find the points on the line x=1
where the circle with equation
2x²+2y²-5x+7y-36-0 intersect
Answer: To find the points where the circle intersects the line x=1, we substitute x=1 in the equation of the circle:
2(1)² + 2y² - 5(1) + 7y - 36 = 0
Simplifying, we get:
2y² + 7y - 31 = 0
We can solve this quadratic equation by using the quadratic formula:
y = (-7 ± √(7² - 4(2)(-31))) / (2(2))
y = (-7 ± √225) / 4
y = (-7 ± 15) / 4
So the two possible values of y are:
y = 2 or y = -8/2 = -4
Therefore, the points where the circle intersects the line x=1 are (1, 2) and (1, -4).

A toy company is building dollhouse furniture. A rectangle door of a dollhouse has a height of 7 centimeters and a width of 3 centimeters. What is the perimeter of the door on a scale drawing that uses the scale 3.5?
Answer: To find the perimeter of the door on a scale drawing, we need to first determine the dimensions of the door on the scale drawing.
If the actual height of the door is 7 centimeters, then the height on the scale drawing will be:
7 cm ÷ 3.5 = 2 cm
Similarly, if the actual width of the door is 3 centimeters, then the width on the scale drawing will be:
3 cm ÷ 3.5 = 0.857 cm
Now we can use these dimensions to find the perimeter on the scale drawing:
Perimeter = 2 × (height + width) = 2 × (2 cm + 0.857 cm) = 2 × 2.857 cm = 5.714 cm
Therefore, the perimeter of the door on the scale drawing is 5.714 centimeters.

Write the equation of the line that passes through the points (3, -4) and (7, 6). Put
your answer in fully simplified point-slope form, unless it is a vertical or horizontal
line.
Answer:
Step-by-step explanation:
To write the equation of the line that passes through the points (3, -4) and (7, 6), we can follow these steps:
Step 1: Find the slope of the line
The slope of a line passing through two points (x1, y1) and (x2, y2) is given by:
slope = (y2 - y1) / (x2 - x1)
Plugging in the given values, we get:
slope = (6 - (-4)) / (7 - 3)
slope = 10 / 4
slope = 5 / 2
Step 2: Use point-slope form to write the equation of the line
Point-slope form of a line with slope m passing through a point (x1, y1) is given by:
y - y1 = m(x - x1)
We can use either of the given points to write the equation. Let's use (3, -4):
y - (-4) = (5/2)(x - 3)
Simplifying this equation, we get:
y + 4 = (5/2)x - (15/2)
Subtracting 4 from both sides, we get:
y = (5/2)x - (23/2)
This is the equation of the line in point-slope form.
Step 3: Simplify the equation if it is not in point-slope form
The equation we obtained in step 2 is already in point-slope form, so we do not need to simplify it any further.
Note: If the line was horizontal (i.e., it had zero slope), then its equation would be y = constant, where the constant is the y-coordinate of any point on the line. If the line was vertical (i.e., its slope was undefined), then its equation would be x = constant, where the constant is the x-coordinate of any point on the line.
Tara creates a budget for her weekly expenses. The graph shows how X much money is in the account at different times. Find the slope of the line. Then tell what rate the slope represents.
The slope of the line is -50 and it means that the amount of money in the account is decreasing at a rate of $50 every week.
What is meant by the slope of the line?
A line's slope is defined as the ratio of the change in the y coordinates to the change in the x coordinate. Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively.
As a result, m = change in y/change in x is the formula for the change in the y-coordinate with respect to the change in the x-coordinate.
where "m" represents a line's slope.
A line's slope provides information on the steepness and direction of the line. By calculating the difference between the coordinates of the two points, (x1,y1) and (x2,y2), it is simple to calculate the slope of a straight line between them.
The complete question is given below.
The two points on the graph are (4, 2400) and (12, 2000).
(x₁ , y₁) = (4, 2400)
(x₂ , y₂) = (12, 2000)
The slope of the graph can be found using the following formula.
Slope m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] = [tex]\frac{2000-2400}{12-4}[/tex] = [tex]\frac{-400}{8}[/tex] = -50
Therefore the slope of the line is -50 and it means that the amount of money in the account is decreasing at a rate of $50 every week.

Avani is trying to find the height of a radio antenna on the roof of a local building. She stands at a horizontal distance of 21 meters from the building. The angle of elevation from her eyes to the roof ((point AA)) is 38^{\circ} ∘ , and the angle of elevation from her eyes to the top of the antenna ((point BB)) is 46^{\circ} ∘ . If her eyes are 1.66 meters from the ground, find the height of the antenna ((the distance from point AA to point BB)). Round your answer to the nearest tenth of a meter if necessary.
Answer:
Let's call the height of the antenna "h".
First, we can use the angle of elevation of 38^{\circ} ∘ to find the height of point A above the ground.
tan(38^{\circ}) = \frac{h}{21}
h = 21 \cdot tan(38^{\circ})
h \approx 15.6
So point A is approximately 15.6 meters above the ground.
Next, we can use the angle of elevation of 46^{\circ} ∘ to find the height of point B above the ground.
tan(46^{\circ}) = \frac{h}{d}
h = d \cdot tan(46^{\circ})
We can find the value of "d" using the Pythagorean theorem.
d^2 = 21^2 + 15.6^2
d \approx 25.7
So the distance from point A to point B is approximately 25.7 meters.
Finally, we can use the height of point A and the distance from point A to point B to find the height of point B (the height of the antenna).
h = d \cdot tan(46^{\circ})
h \approx 25.7 \cdot tan(46^{\circ})
h \approx 23.2
Therefore, the height of the antenna is approximately 23.2 meters.
Step-by-step explanation:
the scenario creates 2 right-angled triangles.
both have the same first leg : the horizontal distance from Avani's eyes to the building (21 m).
and both have a right angle (90°) at the point, where the horizontal distance meets the building.
the difference is now the second leg : the height of the building (starting at 1.66 m above ground), and the height of the building plus the height of the antenna (again starting at 1.66 m above ground).
another difference is the length of the line of sight (from Avani to AA, and from Avani to BB).
driving these differences is the difference in the angle at Avani (38° vs. 46°).
now, remember the law of sine :
a/sin(A) = b/sin(B) = c/sin(C)
a, b, c are the sides of the triangle, A, B, C are the corresponding opposite angles of the triangle.
and remember : the sum of all angles in a triangle is always 180°.
what is the plan ?
we need to calculate the second leg of the larger triangle, and then the second leg of the smaller triangle and subtract that from the second leg of the larger triangle.
in other words :
(building + antenna) - building = antenna
so, we start with the larger triangle (up to BB).
the angle at Avani is 46°.
the angle at the building is 90°.
the angle at BB is then
180 - 90 - 46 = 44°.
21/sin(44) = (building + antenna)/sin(46)
(building + antenna) = 21×sin(46)/sin(44) =
= 21.74613659... m
now, for the smaller triangle (up to AA).
the angle at Avani is 38°.
the angle at the building is 90°.
the angle at AA is then
180 - 90 - 38 = 52°.
21/sin(52) = building/sin(38)
building = 21×sin(38)/sin(52) = 16.40699816... m
the height of the antenna is then again
(building + antenna) - building = 5.339138433... m
≈ 5.3 m

The rock will be at a height of 125 feet after 0.49 and 4.76 seconds.
Finding the time:In the given problem we have a function h(t) that represents the height of the rock that is from the ground of the beach where the variable represents the time travel by the rock.
Assume t as required time equates the given function to the given height and solve for the value of 't'.
Here we have
A rock is thrown directly upward with an initial velocity of 79 feet per second from a cliff 50 feet above a beach.
The height of the rock above the beach (h) after t seconds is given by the equation h(t) = -16t² + 79t + 50.
Let after t seconds the height will be 125 feet
=> h(t) = 125
=> -16t² + 79t + 50 = 125
=> -16t² + 79t - 75 = 0
To solve this quadratic equation, we can use the quadratic formula:
=> x = [-b ± √(b² - 4ac)]/ 2a
Here a = -16, b = 79, and c = -75.
t = [-79 ± √(79² - 4(-16)(-75))] / 2(-16)
t = (-79 ± √(6241 - 4800)) / -32
t = (-79 ± √1441) / -32
So, the two solutions are:
t = (-79 + √1441) / -32 and t = (-79 - √1441) / -32
t ≈ 0.497 or t ≈ 4.763
Therefore,

Find the equation of a straight line with the following gradients and points .1. 2,(7,2) .2. -2(6,-3)
Answer:
The gradient is given as m=1, and the point (7,2) lies on the line. Thus:
y - y1 = m(x - x1)
y - 2 = 1(x - 7)
y - 2 = x - 7
y = x - 5
So the equation of the line is y = x - 5.
Again, using the point-slope form of a straight line:
The gradient is given as m=-2, and the point (6,-3) lies on the line. Thus:
y - y1 = m(x - x1)
y - (-3) = -2(x - 6)
y + 3 = -2x + 12
y = -2x + 9
So the equation of the line is y = -2x + 9.

After simplifying a mixed number is 5 1/16
A mixed number is a combination of a whole number and a fraction.
It is typically written in the form "a b/c", where "a" is the whole number, "b" is the numerator of the fraction, and "c" is the denominator of the fraction.
For example, 3 1/2 is a mixed number, where 3 is the whole number, 1 is the numerator of the fraction, and 2 is the denominator of the fraction. This mixed number can also be expressed as an improper fraction as follows:
3 1/2 = (3 × 2 + 1) / 2 = 7/2.
Conversely, an improper fraction can be converted to a mixed number by dividing the numerator by the denominator to obtain the whole number and expressing the remainder as a fraction.
To multiply 2 1/4, follow these steps:
1. Convert the mixed number to an improper fraction: 2 1/4 = (2 × 4 + 1) / 4 = 9/4
2. Multiply the improper fraction by itself: (9/4) × (9/4)
3. Multiply the numerators: 9 × 9 = 81
4. Multiply the denominators: 4 × 4 = 16
5. Write the result as a fraction: 81/16
6. Simplify the fraction by converting it to a mixed number:
81 ÷ 16 = 5, with a remainder of 1.
So, 81/16 = 5 1/16.

The perihelion is?
The equation for the orbit of planet A around the sun is?
The perihelion is the point in a planet's orbit where it is closest to the sun.
The equation for the orbit of a planet around the sun depends on various factors, such as the shape of the orbit, the mass of the planet, and the gravitational force between the planet and the sun. Kepler's laws of planetary motion provide a framework for understanding the motion of planets in orbit, and the equations used to describe these orbits are generally based on these laws. The specific equation for the orbit of planet A would depend on the specific parameters of that planet's orbit.
The demand for a product is given by p+5q= 380 or, q = (380-p)/5 and the supply for this product is given by p-3q = 172 or, q = (p-172)/3 The price at which the quantity demande
Answer:
The equilibrium price is $250.
The equilibrium quantity is 26 units.
Step-by-step explanation:
To find the equilibrium price, we need to find the price at which the quantity demanded equals the quantity supplied. This occurs when q (quantity demanded) equals q (quantity supplied).
So, we can set the two equations for q equal to each other:
(380-p)/5 = (p-172)/3
To solve for p, we can cross-multiply and simplify:
3(380-p) = 5(p-172)
1140 - 3p = 5p - 860
1140 + 860 = 8p
2000 = 8p
p = 250
Therefore, the equilibrium price is $250. We can plug this value back into either equation for q to find the equilibrium quantity.
Using q = (380-p)/5, we get:
q = (380-250)/5 = 26
So the equilibrium quantity is 26 units.
What is 24 and 816,000 equals blank divided by 10 to the fifth power
Answer: We have the equation:
24,816,000 = x / 10^5
To solve for x, we can multiply both sides by 10^5:
24,816,000 * 10^5 = x
Using a calculator or long multiplication, we can simplify this to:
2,481,600,000,000 = x
Therefore, 24,816,000 is equal to 2,481,600,000,000 divided by 10 to the fifth power.

I need help with the graph about it increasing and decreasing!!
Answers:
Increasing: [tex](-1.5, 2)[/tex]
Decreasing: [tex](-\infty,-1.5) \cup (2,\infty)[/tex]
==================================================
Explanation:
A function curve is considered increasing when moving uphill as you move to the right.
We're going uphill on the interval [tex]-1.5 < \text{x} < 2[/tex] which translates to the interval notation [tex](-1.5, 2)[/tex]. Be sure not to confuse this with ordered pair notation which unfortunately looks identical. The curved parenthesis are used to exclude each endpoint.
-------------
When moving to the right, we go downhill on two separate regions:
When x < -1.5, aka [tex]-\infty < \text{x} < -1.5[/tex]When x > 2, aka [tex]2 < \text{x} < \infty[/tex]The first portion translates to the interval notation [tex](-\infty,-1.5)[/tex]
The second portion translates to [tex](2,\infty)[/tex]
We glue those regions together with a union symbol to get [tex](-\infty,-1.5) \cup (2,\infty)[/tex]
The union symbol basically means "or" when it comes to interval notation. So we are decreasing on the interval [tex](-\infty,-1.5)[/tex] or decreasing on the interval [tex](2,\infty)[/tex]
