The water height of a pool is determined by 5g2 + 3g − 2, the rate that the pool is filled, and 6g2 − 4g − 3, the rate that wate
lyudmila [28]

Answer:

h_g=-g^2+7g+1\\\\h_1=7\\\\h_2=11\\\\h_3=13\\\\h_4=13

Step-by-step explanation:

Given the rate of filling is 5g^2+3g-2 and the rate of emptying the pool is 6g^2-4g-3. The height of the pool at any time is:

h_t=R_{in}-R_{out}, h_t- \ height \ at\  time\  t\\\\h_t=(5g^2+3g-2)-(6g^2-4g-3)\\\\h_t=-g^2+7g+1

#Substitute the value of g in the height equation to find the height of the pool:

#g=1

h_t=-g^2+7g+1, \ g=1\\\\h_t=-(1)^2+7(1)+1\\\\=7

#g=2

h_t=-g^2+7g+1, \ g=1\\\\h_t=-(2)^2+7(2)+1\\\\=11

#g=3

h_t=-g^2+7g+1, \ g=1\\\\h_t=-(3)^2+7(3)+1\\\\=13

#g=4

h_t=-g^2+7g+1, \ g=1\\\\h_t=-(4)^2+7(4)+1\\\\=13

You see how these 2 angles marked are both inside the 2 parallel lines?

And they are on opposite side of the transversal, the line crossing the 2 parallel lines?

These 2 angles are alternate interior angles and they are equal, I think you can do the last part by yourself.

What is -4/9*(-7/9)?
seropon [69]
Hello! So both numbers are negative, so the answer will definitely be positive. All you have to do is multiple straight across. 4 * 7 is 28 and 9 * 9 is 81. That’ll make the fraction 28/81. The product is 28/81.
