I am pretty sure the value of ‘n’ is 2.5!

Step-by-step explanation:

perimeter of a triangle is sum of its side

perimeter of a triangle = 3 ×side

let side be n

15=3×n

15/3=n

5= n

so the side of the triangle is 5 or the value of n is 5

Use differentials to estimate the amount of paint needed (in m3) to apply a coat of paint 0.04 cm thick to a hemispherical dome

pogonyaev

The amount of paint is the volume of paint needed.

The amount of paint needed is 0.065312 cubic meters

<h3>How to determine the amount of paint needed</h3>

The volume of a hemisphere is:

$V = \frac 23\pi r^3$

Differentiate the above equation

$V' = 2\pi r^2 r'$

The above equation represents the estimate of the amount of paint needed.

Where:

r represents the radius (r = 52/2 m)
r' represents the thickness (r' = 0.04 cm)

So, we have:

$V' = 2\pi r^2 r'$

$V' = 2 * 3.14 * (52/2\ m)^2 * (0.04cm)$

$V' = 2 * 3.14 * (26\ m)^2 * (0.04cm)$

Express cm as m

$V' = 2 * 3.14 * (26\ m)^2 * (0.0004m)$

$V' = 0.065312 m^3$

Hence, the amount of paint needed is 0.065312 cubic meters

If f(x)= x*2 +3 and g(x) = 4x + 1, what is f(g(2))?

enot [183]

Answer:

f(g(2))=84

Step-by-step explanation:

Step one:

Given data

f(x)= x*2 +3

g(x) = 4x + 1

Step two

Let us find g(2) first then we proceed to find f(g(2))

g(2)=4(2) +1

g(2)=8+1

g(2)=9

Since g(2)=9

f(g(2))=x*2 +3

f(g(2))=9*2 +3

f(g(2))=81+3

f(g(2))=84

An Object Speeds Up From 15 m/s to 55 m/s in only 8 s when a force of 100N Is Applied on it. What Is The Mass of the Object?

Kipish [7]

Answer:

500g

Step-by-step explanation:

Because the domula of acceleration is v-u/t so initial velocity is 15 and final velocity is 55 and mass is force * acceleration
