Answer:
b = 2A/h
Step-by-step explanation:
The formula for area of a triangle is
A = 1/2 bh where b is the base and h is the height
We want to find the base
Multiply each side by 2
2A = 2*1/2 bh
2A = bh
Divide each side by the height
2A/h = bh/h
2A /h = b
b = 2A/h
Slope intercept form will help you find the function of the line :) [ y = mx + b ]
at time = 0 (y-intercept) the pool is 72in deep
the pool loses 2 inches of water every 1 hour. or -2/1
so your equation is y = -2x + 72
Good Luck!
Y - y₁ = m(x -x₁)
slope m = -2, from point (10, -9) , x₁ = 10, y₁ = -9
y - y₁ = m(x -x<span>₁)
</span>y - -9 = -2(x - 10<span>)</span><span>
y + 9 = -2(x - 10) </span>
Answer:
The new length of the tear is 2.3 * 10^-2 inch
Step-by-step explanation:
Here, we are concerned with knowing the new length of the tear.
Originally, the length of the tear is 2.3 * 10^-4 inch.
But this tear became 100 times longer. The new length of the tear will be the old length * 100
Mathematically, that would be 2.3 * 10^-4 inch * 100
= 2.3 * 10^-4 * 10^2
= 2.3 * 10^(-4 + 2)
= 2.3 * 10^-2 inch
