If the volume of the expanding cube is increasing at the rate 24 cm3 / min , how fast is its surface area increasing when the su

Georgia [21]

Answer:

16 cm^2/min

Step-by-step explanation:

dV/dt=24

V=a^3, differentiate with respect to t

dV/dt=3a^2*da/dt, a^2*da/dt=8

S=6a^2, 216=6a^2. a=6. da/dt=(8/36)

dS/dt=12*a*da/dt=12*(8/6)=16 cm^2/min

Y=1/4x+7 y=1/2x+5 The y-coordinate of the solution to the system shown is _____.

Brilliant_brown [7]

Answer:

The y-coordinate of the solution to the system shown is 9

Step-by-step explanation:

$y=\frac{1}{4}x+7\\y=\frac{1}{2}x+5$

We need to solve these system of equations and find value of y

Let eq (1) be $y=\frac{1}{4}x+7$

and eq(2) be $y=\frac{1}{2}x+5$

Putting value of y from eq(2) into eq(1)

$y=\frac{1}{2}x+5=\frac{1}{4}x+7\\\\\frac{1}{2}x-\frac{1}{4}x=7-5\\\frac{2x-x}{4}=2\\\frac{x}{4}=2\\x=2*4\\x=8$

Putting value of x=8 in equation 1 to find value of y

$y = \frac{1}{4}x+7$

$y = \frac{1}{4}(8)+7$

$y =2+7$

$y =9$

So, The y-coordinate of the solution to the system shown is 9
