Answer:

c. 25.12

this can just be estimated- 8 x pi- or, to make it easy just do 8 x 3= 24. that gets you in the ballpark, and the only answer close is C

Answer:

f^{-1}(x)=x^2+1

Step-by-step explanation:

The inverse of a function is when the x and y are swapped. So the first step is to write f(x) as y and then swap the x and y

Original Equation:

f(x)=\sqrt{x-1}\\

write f(x) as y (since that's what it represents)

y=\sqrt{x-1}

Swap x and y

x=\sqrt{y-1}

Square both sides

x^2=y-1

Add 1 to both sides

x^2+1=y

So this gives you the equation:

f^{-1}(x)=x^2+1

Two kids are roller skating. Amy, with a mass of 55 kg, is traveling forward at 3 m/s. Jenny, who
alekssr [168]

Answer:

They traveling at 0.37\ m/s in backward direction.

Step-by-step explanation:

Given mass of Ammy m_1=55kg

and velocity is forward at v_1=3m/s

Also, mass of Jenny m_2=40kg

Who is travelling in opposite direction v_2=-5m/s

Let velocity in forward direction is positive and velocity in backward direction is negative.

Also, velocity after crash is v

As they crashed into each other and they moved as one mass. We can apply principle of conservation of momentum.

Conservation of momentum says momentum before collision should equal to momentum after collision.

m_1v_1+m_2v_2=(m_1+m_2)v

(55\times3)+(40\times(-5))=(55+40)v\\\\165-200=95v\\\\-35=95v\\\\v=\frac{-35}{95}=-0.368m/s

So, velocity after collision v≅-0.37m/s is in opposite direction. That is the direction of Jenny.

2. Mr. Frank tyses 12 emails per<br> day. How long will it take him to<br> write 60 emails?
Nezavi [6.7K]

Answer:

5 days

Step-by-step explanation:

We can use a ratio to solve

12 emails        60 emails

--------------- = --------------

1 day              x days

Using cross products

12*x = 1 * 60

12x = 60

Divide each side by 12

12x/12 = 60/12

x =5

It will take him 5 days
