for A is-48
nd B is-16.5
nd C is-32.4
Answer:
Step-by-step explanation:
(10 - x^2)/b = b/2
Cross multiply
2(10 - x^2) = b^2
20 - 2x^2 = b^2
2x^2 = 20 - b^2
Dividing through by 2
x^2 = (20 - b^2)/2
√x^2 = √(20 - b^2)/2
x = √(20 - b^2)/2
Answer: Radius = 8.575 cm Step-by-step explanation: Formula for volume of a pyramid is; V_p = ½Ah Where A is area of base and h is height Also, formula for volume of cone is given as; V_c = ⅓πr²h Now, we are told that V_p = V_c and that h is the same for both shapes. Thus ; ½Ah = ⅓πr²h h will cancel out to give; ½A = ⅓πr² Cross multiply to give; 3A/2π = r² Base area of pyramid is given as 154 cm². Thus; (3 × 154)/2π = r² r = √((3 × 154)/2π r = 8.575 cm

Because it can not be approximately pointed on a graph.
There are two ways:
One if you have a graphing calculator (TI-84 plus) you can go to stat then edit then type in the -40 and -90 on the left and the -120 and 60 on the right. The press stat again and go to the right to calc the down to linreg (ax +b) and go down to calculate amd press enter.
Your answer is y = -3.6x+-264
option two is by hand
the formula is y1-y2 divided by x1-x2
