Write an equation for the line through (3.5,-2.3) x intercept 5.1

1 answer:

4 0

Slope = (-2.3 - 0)/(3.5 - 5.1) = -2.3/-1.6 = 1.4
The line's equation is 
y - 0 = 1.4(x - 5.1) 
y = 1.4x - 7.1

Write the equation of an exponential function that passes through the points (2,48) and (5,750).

Otrada [13]

Ok, so the function form is y = a * bx.
Substitute in the values:
750 = a * b5
and
48 = a * b2
Then divide the two equations:
750/ 48 = (a * b5) / (a * b2)
So:
15.625 = b3
Take the cube root of both sides:
2.5 = b
Now, substitue b into one of the equations (the one with 48 has smaller numbers and is easier to work with.)
48 = a * 2.52
Simplify.
48 = a * 6.25
Divide both sides by 6.25
7.68 = a
Now substitute in a and b to write the exponential function:
y = 7.68 * 2.5x

1. A cube has a volume of 125 cubic inches. What is the length of each edge?

Anettt [7]

Answer:

5 inches

Step-by-step explanation:

Since the length of the sides of a cube are all equal,

volume of cube

= side ×side ×side

= (side)³

125= (length of side)³

Cube root both sides:

Length of each edge

$= \sqrt[3]{125}$

= 5 inches
