What is the value of the range of the function f(x)=2x^2-3x+8 for the domain value 3
Lelechka [254]
The domain is the same as the x value and the range is the same as the y value, so you just plug in the 3 to all the x's.

f(x) = 2 ({3})^{2}  - 3(3) + 8 \\ f(x) = 18 - 9 + 8 \\ f(x) = 17
the range of the function is 17

an object is launched upward from ground level and reaches a maximum height of h feet. The initial velocity v (in feet per secon
DIA [1.3K]
<span>So we want to rewrite the function v=8h^2 in terms of h so that it can represent the height of an object that is launched upward. So we take a square root: sqrt v= h*sqrt 8. Then we divide both sides of the equation with sqrt 8: h=(sqrt v)/sqrt 8=sqrt(v/8). So our function is: h=sqrt(v/8) or h=(1/2)*sqrt(v/2). </span>

A square poster has a side length of 26 in. Drawn on the poster are four identical triangles. Each triangle has a base of 8 in.
Firdavs [7]
To find the probability of landing on a triangle, you will want find the combined areas of the triangles and the total area of the square target.

Divide the area of the combined areas and the total area to find the probability of landing on a triangle.

A = 1/2bh
      1/2 x 8 x 8
A = 32 square inches
32 x 4
128 square inches (areas of triangles)

A = bh
     26 x 26
A = 676 square inches

128/676 = 0.189

There is an approximate probability of 0.19 of hitting a triangle.
