a = 7b = 14c = 7d = 7*sqrt(3)======================================================
Explanation:
The smaller triangle on the left is a 45-45-90 triangle. In these triangles, the hypotenuse is sqrt(2) times that of the leg length.
The hypotenuse shown is 7*sqrt(2), so that must mean each leg is 7 units long. Therefore, a = c = 7.
The triangle on the right is a 30-60-90 triangle. The shorter leg (opposite the smallest angle of 30 degrees) doubles to get the hypotenuse. So we can say b = 2a = 2*7 = 14. The longer leg is exactly sqrt(3) times that of the shorter leg. The longer leg is d = a*sqrt(3) = 7*sqrt(3)
h(x)=1x-21, find h(-10)
Answers
Answer:
h(-10) = -31
Step-by-step explanation:
Substitute -10 for x in h(x)=1x-21:
h(-10) = 1(-10) - 21, or
h(-10) = -10 - 21 = -31
h(-10) = -31
Can someone help me with these questions
Answers
For example:
2x + 7 + 8x + 3
What you want to do is simply the expression
We can see that 2x and 8x are both coefficients
(A coefficient is a number that is going to be multiplied by a variable such as 3y, 2x, 7x and so on)
They are both like terms meaning that they can be combined
2x + 8x= 10x
Next, you want to see if you can combine anything else because our goal is to make the expression simplified.
7 and 3 can be combined because they are like terms
7+3= 10
Now that you have the new numbers I guess you can call it your answer should be
10x + 10
Hopefully this helps you answer the other questions. I did this lesson not too long ago so if you need help on anything else I can try to explain it.
y=5x−2 into polar form
Answers
Answer:
r·sin Ф = 5(r·cos Ф) - 2
Step-by-step explanation:
y = r·sin Ф and x = r·cos Ф, and so
y = 5x - 2 becomes
r·sin Ф = 5(r·cos Ф) - 2
Answer:
rsin(0) = 5rcos (0) - 2
Step-by-step explanation:
Convert y = 5x - 2 to polar coordinates.
To convert to polar apply: x = r · cos (0), y = r · sin (0)

Answer: B
The Vertical Angles Theorem states that vertical angles, angles that are opposite each other and formed by two intersecting straight lines, are congruent. This means that 48° should equal (7x+13)°, because they're vertical angles. The equation should appear as 48=7x+13. Subtract 13 on both sides to get. 35=7x. Divide 7 on both sides to result with x=5.

1. A box without a top is to be made from a rectangular piece of cardboard, with dimensions 3 in. b)
in., by cutting out square corners with side length x and folding up the sides.
Answers
Answer:
a) The volume of the box is represented by [tex]V = 21\cdot x - 20\cdot x^{2}+4\cdot x^{3}[/tex].
b) A side length of 0.653 inches leads to the maximum volume of the box: 6.299 inches.
Step-by-step explanation:
a) The volume of the box ([tex]V[/tex]), in cubic inches, is modelled by the equation for the cuboid:
[tex]V = (3-2\cdot x) \cdot (7-2\cdot x) \cdot x[/tex] (1)
Where [tex]x[/tex] is the side length of the cutted square corners, in inches.
[tex]V = (21 - 20\cdot x + 4\cdot x^{2})\cdot x[/tex]
[tex]V = 21\cdot x - 20\cdot x^{2}+4\cdot x^{3}[/tex]
The volume of the box is represented by [tex]V = 21\cdot x - 20\cdot x^{2}+4\cdot x^{3}[/tex].
b) The method consist in graphing the polynomial and looking for a relative maximum. We graph the equation found in a) by means of a graphic tool. We present the outcome in the image attached below. According to this, a side length of 0.653 inches leads to the maximum volume of the box: 6.299 inches.

Answers
The green object below, is best defined as a Ray named AC.
In geometry, a ray is a part of a line that consists of a single initial point called the endpoint and extends infinitely in one direction. It can be thought of as a half-line, with one end point and the other end extending infinitely.
Rays are named using two points, with the endpoint being mentioned first.
Here, in the figure the green line has one point A and the next C and it is further extending.
Thus, the Green line is a Ray name as ray AC.

Step-by-step explanation:
look at the number line. I always had trouble with this so I get where your coming from first, look at where the line is touching don't pay attention to the box yet because it's confusing the entire point of this line is to show you that there MAY have been 1 or two people who where at 0 for this data and 1 or two people who were at 15
the point here is that the bulk of the data was 11-14, but because there were less people down lower, the mean of the data is at 13, and the data is bigger (skewed) to the left.

Find the slope of the line through the points (-4, 3) and (3, 5)
Answers
Answer: 2/7
Step-by-step explanation:
Slope is ∆y/∆x. ∆ is read as "delta". The "delta" sign means "the difference between". So that means the difference between the y-coordinates divided by the x-coordinates gives us slope. Therefore, using the coordinates, 5-3 gives us the rise. And 3-(-4) gives us the run. Rise/Run is also equivalent to the slope. Thus, our final answer is 2/7.
if 100 students surveyed, 25 said they would vote for Jen for class president. If 2,000 students voted in the school's election, about how many votes should Jen receive?
A 25
B 100
C 500
D 1,900
Answers
Answer:
500 Votes
Step-by-step explanation:
25/100 = 0.25
500/2000 = 0.25
Therefore 500 students would vote for Jen.
The reason is because only a quarter of 100 said they'd vote which is found by doing 25/100 = 1/4 or 25% or .25 (all mean the same)
Apply that to 2000 by doing 2000 x 1/4 (or .25) and it should be 2000 x 1/4 = 500

We can infer here that the inverse tangent is used to find a missing angle measure when we are given the opposite side and the adjacent side.
What is inverse tangent?An inverse tangent is known to be the formula that is used to find an angle of a right-angled triangle when certain sides are given. This is true when opposite and adjacent sides are given.
Thus, to find an angle using inverse tangent, we will have: θ = tan-1[ (opposite side) / (adjacent side) ].

Answers
Find the slope of points A and B
(y2 - y1)/ (x2-x1)
(5-(-5))/(-1-(-2)) = (5+5)/(-1+2) = 10/1
The slope of the points is 10
In the equation
y = 10x + 12
Y = mx + b, m indicating slope
The slope of the equation is also 10
Because both slope is 10, the line through the points and the equation is parallel
