Answer:
Linear
y = -30x + 100
Step-by-step explanation:
The table has a set of inputs with matching outputs. The behavior of the outputs will determine the type of function. The outputs appear to descend at a constant subtraction rate of -30 each time.
70 - 30 = 40
40 - 30 = 10
10 - 30 = -20
etc.
A constant addition or subtraction rate is a slope. Since the function has a slope, this is a linear function.
To write the function you'll need a slope and a y-intercept. Recall, the y-intercept is where x = 0. This is not in the table but can be found by reversing the process by adding 30 + 70 = 100.
Substitute m = -30 and b = 100 into y = mx+b for the equation.
y = -30x + 100
To find the surface area (SA) multiply length*height*2 and to find volume multiply length*width*height
7.5 what? what is the conversion supposed to be?
Answer:
A
Step-by-step explanation:
Area of the unshaded region = 95/360 * 3.14 * (5*√2)^2
Area of the unshaded region = 95/360 * 3.14 * 50
Area of the unshaded region = 41.43
Area of the entire circle = pi r^2
Area of the entire circle = 3.14 * (5√2)^2
Area of the entire circle = 157
Area of the shaded part = The whole circle's area - the unshaded part
Area of the shaded part = 157 - 41.42
Area of the shaded part = 115.57
