Please answer correctly !!!! Will mark brainliest !!!!!!!!!!!!!!
Step-by-step explanation:
Adding 10 to both sides of the original equation gets us q = 6(r + 1) + 10. Since q is equal to h(r), we get h(r) = 6(r + 1) + 10 = 6r + 16.

Answer:
3. 12.5π + 100
6. 25π + 250
Step-by-step explanation:
3. So you can first calculate the area of the square, which is 100.
Then you have to calculate the semicircle.
You can see that the diameter is 10.
The radius is 5.
The area of the semicircle is 12.5π
Total area is 12.5π + 100
6. You have a one rectangle and two semicircles.
You can calculate the area of the semicircles first.
25π
Then, you have to see how much the width of the rectangle is.
You can see that the total width is 35, and the radius of each semicircle is 5.
35 - 5 - 5 = 25
The width is 25 so the area of the rectangle is 250.
The total is 25π + 250.

find K if the sum of the zeros of the polynomial x square - (K + 6 ) x + 2( 2 k - 1) is half the product
k=7
given a quadratic polynomial
ax^2+bx+c
the sum of the roots is given by -(b/a)
and the product of the roots as (c/a)
hence we get sum of roots as -(-(k+6)/1) and product of roots as (2(2k-1))/1
since the sum is equal to half the Product then we get
k+6=2k-1 and solving for k we get 7

1.) Which variable did you plot on the x-axis, and which variable did you plot on the y-axis? Explain why you assigned the variables in that way.
2.) Write the equation of the line of best fit using the slope-intercept formula y = mx + b. Show all your work, including the points used to determine the slope and how the equation was determined.
3.) What does the slope of the line represent within the context of your graph? What does the y-intercept represent?
4.) Test the residuals of two other points to determine how well the line of best fit models the data.
5.) Use the line of best fit to help you to describe the data correlation.
6.) Using the line of best fit that you found in Part Three, Question 2, approximate how tall is a person whose arm span is 66 inches?
7.) According to your line of best fit, what is the arm span of a 74-inch-tall person?
Answer:
1) On the x-axis, the arm span is plotted. On the y-axis, the height is plotted. It is chosen to be that way because the numbers on that have been assigned on the x-axis increase and decrease in a small amount, while the numbers on the y-axis increase and decrease in a huge amount.
2) (lolz i cant show u my work but i will try my best with explanations even tho ian allat.) So, Using the slope formula, I got a the equation y=x+15. The equation was determined with the formula m=y2-y1/x2-x1. The points that were used included (37,40) and (47,50). After finding the slope, I did the best guess for the y-intercept, which is known as b in y=mx+b.
3) The slope of the line represents the time it takes for the arm span and the height. The y-intercept represents the height that the arm span starts developing or gets bigger.
4) It fits perfectly
5) The data is pretty inconsistent.
6) About 68-69 inches tall
7)About 71-72 inches wide

which graph shows a reflection across the y-axis?
Answer:
A.
Step-by-step explanation:
graph a shows reflection across the y axis
Answer:
the correct answer is B
Step-by-step explanation:
the image for A is incorrect because that would be reflecting across the x-axis
the image for B is correct because it is literally going across the y-axis (ik it sounds very simple but it's true)
the image for C is incorrect because it doesn't even go across the y-axis or x-axis, it's only in the third quadrant

Which are vertical angles? Check all that apply. ∠EAB and ∠BAC ∠EAB and ∠CAD ∠CAD and ∠FAE ∠CAB and ∠DAE ∠DAC and ∠DAE
Answer:
<CAB and <DAE are vertical angles
<EAB and <CAD are vertical angles
Step-by-step explanation:
this is because they are formed by the prolongation of the sides of the other angles and are opposite to them on the other side of the vertex.
Options B and D are correct. The vertical angles are ∠CAD and ∠BAE AND ∠EAB and ∠CAD.
Vertical angles are angles that are opposite to each other in line geometry. The size of the angles must be the same.
According to the diagram shown, we can see that ∠CAD and ∠BAE are opposite to each other with similar measures.
This means that both angles are vertically opposite. he same is applicable to ∠EAB and ∠CAD.Hence the vertical angles are ∠CAD and ∠BAE AND ∠EAB and ∠CAD.

The length of TR is 17 units. What are the lengths of SV and QT? (please hurry i dont get this question) also i need each individual answer, not SV + QT, I need SV and QT
Answer:
QT = 21SV = 41Step-by-step explanation:
From the diagram, it can be seen that TR is parallel to RV. This means that TR = RV. Given TR = 17 and RV = 3x+2
3x+2 = 17
3x = 17-2
3x = 15
x = 5
RV = 3(5)+2 = 17
QV = 4x+1 = 4(5)+1
QV = 21
Using Pythagoras theorem on ΔQRV to get RQ
QV² = QR²+RV²
21² = QR²+17²
QR² = 21²-17²
QR = 12.33
Using Pythagoras theorem on ΔQRT to get QT
From ΔQRT,
QT² = QR²+TR²
QT² = 12.33²+17²
QR² = 152.0289+289
QT² = 441.0289
QT =21
Since TS = 9(5)-4 = 41
Using Pythagoras theorem on ΔTRS
From ΔTRS,
TS² = RS²+TR²
41² = RS²+17²
RS² = 41²-17²
RS² = 1392
RS = 37.31
Similarly Using Pythagoras theorem on ΔRSV
From ΔRSV,
SV² = RV²+RS²
SV² = 17²+37.31²
SV² = 1681.0361
SV = 41
Answer:
SV=41
QT=21

solve for t
Answer:
t can equal 7 or -7
Step-by-step explanation:
Answer:
t=7 or t=-7
Step-by-step explanation:
To solve for t, we need to get t alone. To do this, perform the opposite of what is being done to the equation. Keep in mind, everything must be performed to both sides.
t^2=49
t is being squared. The opposite of squared is the square root. Take the square root of both sides.
√t^2=√49
t=√49
t=±7
So, t is equal to 7 or -7
