F(x) = square root 32x <br> g(x) = square root 2x
otez555 [7]

Given:

The two functions are:

f(x)=\sqrt{32x}

g(x)=\sqrt{2x}

To find:

The (f\cdot g)(x). Assume x\geq 0.

Solution:

We have,

f(x)=\sqrt{32x}

g(x)=\sqrt{2x}

Now,

(f\cdot g)(x)=f(x)\cdot g(x)

(f\cdot g)(x)=\sqrt{32x}\cdot \sqrt{2x}

(f\cdot g)(x)=\sqrt{32x\times 2x}

(f\cdot g)(x)=\sqrt{64x^2}

(f\cdot g)(x)=8x

Therefore, the correct option is A.

What two numbers multiply to 10 and add to -29 ?
Degger [83]
Xy=10
x+y=29

subtract x from both sides for second equation

y=-x-29
subsitute in second equaiton
x(-x-29)=10
-x^2-29x=10
add x^2+29x to both sides
x^2+29x+10=0
quadratic formula
if you have
ax^2+bx+c=0,
x=\frac{-b+/- \sqrt{b^{2}-4ac} }{2a}

so
x^2+29x+10=0
a=1
b=29
c=10
x=\frac{-29+/- \sqrt{(-29)^{2}-4(1)(10)} }{2(1)}
x= \frac{-29+/- \sqrt{841-40} }{2}
x= \frac{-29+/- \sqrt{801} }{2}
x= \frac{-29+/- 3\sqrt{89} }{2}

x= \frac{-29- 3\sqrt{89} }{2} or \frac{-29+ 3\sqrt{89} }{2}
those are the 2 numbers

What is the measure of EFG in 0 0 below?
const2013 [10]

Answer:

C. 300

Step-by-step explanation:

EFG and EG is the total distance around the circle

EFG + EG = 360 degrees

EFG + 60 = 360

Subtract 60 from each side

EFG +60-60 = 360-60

EFG = 300
