Answer:
They are parallel but they are not equal where y=7x^2 It's y intercept is 0 and for y=7x^2+4 it's y intercept is 4
Step-by-step explanation:
Answer:
dx/dt = 5√5/2
Step-by-step explanation:
Given:
dx/dt = 25 feet per second
According to Pythagoras theorem:
x² + 90² = y²
We know that x = 30 ft
So,
x² + 90² = y²
30² + 90² = y²
y = 30√10
So,
x² + 90² = y²
By taking differentiate:
2x dx/dt = 2y dy/dt
[x/y][dx/dt] = dy/dt
dx/dt = 5√5/2
You gave $30.
[$30 * 0.20] (tip % amount) = $6.
You left $6 in tips.
-4 2/5 / -5
-4 2/5 = -22/5
-5 = -5/1
-22/5 / -5/1
Flip -5/1 to multiply
-22/5 x 1/-5
Numerator x numerator / denominator x denominator
-22 x 1 = -22
5 x -5 = -25
-22/-25 = 22/25
The answer is 22/25.
Answer: y = 10x + 30 is the correct answer
