It's a kite or a rhombus.
Answer: you can find the area of a circle by multiplying the radius by pi and then squaring it by 2
Step-by-step explanation:
10 ft and 2 because I did the math
Answer:
i think b (super clean)
Step-by-step explanation:
9. D because it fits the description when it is graphed.
11. D because it has the correct vertex, which is (1.5, 4.75).
12. f(x)=-4(x-2)²+16 works with the table and provided graph!
13. 0 isn't a zero for f(x), so B is correct (the zeros are 1/2 and 4).
14. The width is about 3.831.
15. The answer is B because the equation for a parabola in this form is:
f(x) = (x - r₁)(x - r₂)
Every one of these except for 15 was solved using desmos, a graphing calculator.
Hope this helps!
