4y
— - 7 = -3
5

Answers

Answer 1

Answer:

4y/5 - 7 = -35

Add 7 to both sides:

4y/5 = -28

Multiply 5 to both sides:

4y = -140

Divivde 4 to both sides:

y = -35

A cone has a volume of 36π ft^3. The height of the cone is 12 ft. Find the diameter of the base of the coneRound to one decimal place if necessary.

Answers

Answer: 6 feet

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a cone= (1/3) π radius² height

Replacing with the values given and solving for r:

36π = (1/3) π r² 12

36π/ [(1/3) π 12]= r²

9 = r²

√9 =r

3 ft = r

Since:

Diameter = 2 x radius

Substituting r=3

D = 2x 3

D = 6 feet

Let f(x)=1/x and g(x)=x^2+5x find (f×g)(x)

Answers

Answer:

(f×g)(x) = x +5.

Step-by-step explanation:

Given : f(x)= $(1)/(x)$ and g(x) = x²+5x.

To find : find (f×g)(x).

Solution: We have given f(x)= $(1)/(x)$ and g(x) = x²+5x.

For (f×g)(x) = f(x) * g(x) .

Plug the values

(f×g)(x) = $(1)/(x)$ * x²+5x.

(f×g)(x) = $(x^(2)+5x )/(x)$

On taking x common from the numerator

(f×g)(x) = $(x(x+5))/(x)$ .

(f×g)(x) = x +5.

Therefore, (f×g)(x) = x +5.

just multiply
remember the distributive proeprty a(b+c)=ab+ac
(f *g)(x)=f(x)g(x)=(1/x)(x^2+5x)=(x^2/x)+(5x/x)=x+5

(f*g)(x)=x+5

It was 96 kilometers from perry to medford. David raced to medford and idled back. If the round trip took 8 hours, what was his average speed in kilometers per hours?

Answers

Average speed = (total distance) / (total time)

Average speed = (192 km) / (8 hours) = 24 km per hour .

Time for round trip = 8 hours

thus, time for trip = 8/2 = 4 hours.

Speed = distance / time

= 96/4 = 24 km/h

Thus, his average speed was 24 km/h
