$p(x)=-16x^2+32x

p(x)=0
$

$-16x^2+32x = 0$

$-16x(x-2)=0$

$x_1=0, x_2=2$

Rocket will be in the air for 2 seconds.

Store 1 earned 10% of the money invested I it while store 2 lost 8% of the amount invested in it. The net total gain was $1,300.

Alex17521 [72]

Answer:

Store 1= $150

Store 2= $250

Step-by-step explanation:

Let the amount invested by store 1 be x while store 2 be y hence

10x-8y=1300 Eqn 1

Make x the subject of the formula for the first equation

10x=1300+8y divide both sides by 10

X=130+0.8y

6x+5y=2250 Eqn 2

Substituting where there’s x with 130+0.8y in equation 2 we obtain

6(130+0.8y)+5y=2250

780+4.8y+5y=2250

9.8y+780=2250

9.28y=2250-780=1470

Y=1470/9.8=150

X=130+0.8y= 130+0.8(150)=250

Kurt enlarges a 24 cm by 30 cm photo to a 60 cm by 75 cm photo. What is the scale factor of the enlargement?

Kipish [7]

One scale factor equation is y=cx
y is the new factor (in this case, 60 or 75)
c is the scale factor (in this case, unknown)
x is the old factor (in this case, 24 or 30)
so: plug in the values
60=c(24) divide both sides by 24
c=2.5

you can check again with the other numbers
75=c(30) divide both sides by 30.
c= 2.5

your scale factor is 2.5
