The coordinates of the vertices of triangle QRS are Q (1,-2), R (1,9),
S (6,-4). What is the length, in units, of the line segment that connects
vertex Q to vertex R?
I think 1700000000000000000
Answer:
QR = 11
Step-by-step explanation:
Q and R are on a vertical line. Therefore, QR = 9 - (-2) = 9 + 2 = 11
Hi can you Please answer this i will mark brainliest ive been asking for 2 days :( Its Overdue :(
Answer:
f(x)= 1.38x
y= 1.38x
Step-by-step explanation:
basically the cost= 1.38 per pound
you can use cost=1.38x if ur grade level isn't at f(x) yet
<3
Answer:
f(x) = 1.38x
x just stands for a number so depending on how many pounds you get you would times the pounds by 1.38. And f(x) (pronounced "f of x") means that each input has a single output. So if you bought 2 pounds of strawberries, the equation would change to this:
f(2) = 1.38(2)
The x's were just replaced with 2's, see? I wish someone had explained this to me earlier lol
What is the intermediate step in the form (x+a)^2=b(x+a)
2
=b as a result of completing the square for the following equation?
6x^2+48x+207=15
Answer:
The intermediate step are;
1) Separate the constants from the terms in x² and x
2) Divide the equation by the coefficient of x²
3) Add the constants that makes the expression in x² and x a perfect square and factorize the expression
Step-by-step explanation:
The function given in the question is 6·x² + 48·x + 207 = 15
The intermediate steps in the to express the given function in the form (x + a)² = b are found as follows;
6·x² + 48·x + 207 = 15
We get
1) Subtract 207 from both sides gives 6·x² + 48·x = 15 - 207 = -192
6·x² + 48·x = -192
2) Dividing by 6 x² + 8·x = -32
3) Add the constant that completes the square to both sides
x² + 8·x + 16 = -32 +16 = -16
x² + 8·x + 16 = -16
4) Factorize (x + 4)² = -16
5) Compare (x + 4)² = -16 which is in the form (x + a)² = b

please help me solve this equation
Answer:
-85
Step-by-step explanation:
We are given the equation [tex]E^8_{n=1}[/tex][tex](-2)^{n-1}[/tex] and are asked to evaluate it.
This can be solved using the geometric sequence, but first we have to determine our "r", "n", and [tex]a_{1}[/tex].
Of course [tex]a_{1}[/tex] is equal to 1. Therefore,
[tex]a_{1[/tex] = 1
[tex]r=[/tex]
[tex]n=[/tex]
(-2) is the change per number in the sequence, therefore -2 is our "r".
[tex]a_{1[/tex] = 1
[tex]r=-2[/tex]
[tex]n=[/tex]
The number "8" on [tex]E^8_{n-1}[/tex] represents the "n". Therefore 8 is our "n".
[tex]a_{1}=1[/tex]
[tex]r=-2[/tex]
[tex]n=8[/tex]
Use the geometric sequence sum formula and substitute :
[tex]a_{1} \frac{1-r^n}{1-r}[/tex]
[tex]1* \frac{1-(-2)^8}{1-(-2)}[/tex]
[tex]1* \frac{1-(-2)^8}{1+2}[/tex]
[tex]1* \frac{1-256}{1+2}[/tex]
[tex]1* \frac{-255}{3}[/tex]
[tex]1 * -85[/tex]
[tex]-85[/tex]

A camper on top of a 400 foot cliff is enjoying the view. They look down and see a
bear at an angle 37 degrees. Approximately how far is the bear from the base of the
cliff? (Round your answer to the nearest foot.). REMEMBER THE UNITS
Answer:
301.42 ft from base
Step-by-step explanation:
We can look at this situation as a triangle, the cliff is straight up and we're looking for the lowest side of the triangle. So to figure this out we use tangent, tangent is equal to Opposite over adjacent. So the tangent(37)= bear from base/height of cliff. We then multiply tan(37) by 400 to get the answer
1.2 ÷ 4 = 12 tenths ÷ 4

Yes you're right, it does

Answer:
Part A
2·a + b ≤ 14
Part B
Please find attached the graph of the inequality created with Microsoft Excel
Part C
1) 4 pounds of apples + 8 pounds of bananas
2) 8 pounds of apples + 6 pounds of bananas
Step-by-step explanation:
Part A
The amount Tony has to buy apples and bananas = $14
The cost of apples per pound = $2
The cost of bananas per pound = $1
Let 'a' and 'b' represent the number of apples and bananas Tony buys respectively, we have;
2·a + b ≤ 14
Part B
In order to plot the inequality, we make one of the variables the subject of the inequality as follows;
b ≤ 14 - 2·a
The above inequality can be plotted with Microsoft Excel and the feasible region shaded as shown in the attached diagram
Part C
Two possible combinations of pounds of apples and bananas that Tony can buy are;
1) 4 pounds of apples and 8 pounds of bananas which gives 2 apples and 8 bananas
2) 8 pounds of apples and 6 pounds of bananas which gives 4 apples and 6 bananas

Let f(-x) = 5x – 2 and g(x) = 2x + 3 and find f(x) –
f(0) — 9(x) = 7x – 1
f(.2) – 9(x) = 7x + 1
f(x) — 9(2) = 3x – 5
f(x) – 9(x) = -3x +5
Answer:
3x - 5
Step-by-step explanation:
Given that f(x) = 5x - 2 and g(x) = 2x+3
f(x) - g(x) = 5x-2 - (2x+3)
Expand
f(x) - g(x) = 5x - 2 - 2x - 3
Collect like terms
f(x) - g(x) = 5x - 2x -2-3
f(x) - g(x) = 3x - 5
Hence the required answer is 3x - 5

Answer:
The line with a slope of 1/2 is steeper
Step-by-step explanation:
Here, we want to get which slope is steeper
mathematically, when we want to know the line that has a steeper slope, we compare the value of the slopes
The line with a slope that is of greater value will be steeper
Mathematically, 1/2 is a greater number than 1/3
That simply means 1/3 is less steep and thus, the line with the slope of 1/2 is the steeper line
