Hi there!  

»»————- ★ ————-««

I believe your answer is:  

18in³

»»————- ★ ————-««  

Here’s why:  

⸻⸻⸻⸻

Assuming that the figure is a rectangular prism:

⸻⸻⸻⸻

\boxed{\text{Volume of a rectangular prism is:}}\\\\V = l * w * h\\-----------\\V = 2 * 2.25 * 4\\\\\boxed{V = 18}

Given the following functions, evaluate f×g(7)
lidiya [134]

0

evaluate g(7) by substituting x = 7 into g(x

g(7) = (49-35-10)/2 = 4/2 = 2

now substitute x = 2 into f(x)

f(2) = √(4 - 48 + 144) = √0 = 0

(f ○ g)(7) = 0

If Dominik completes a project by himself, it will take him 8 hours. Working with Katarina, it will take them 5 hours. If they w
Marysya12 [62]
The main formula we use here is Work=Rate*Time,


1. The rate (speed of working) of Dominik is 

r_D=1project/8hours= \frac{1}{8}(prj/h)

2. Let the the rate of Katarina be r_K=x(prj/h)

Together they have a rate of r_D_K equal to \frac{1}{8}+x (project per hour)

so (\frac{1}{8}+x) ( \frac{proj}{hr})*5(hr)=1(proj)

simplify the units:

(\frac{1}{8}+x) *5=1

\frac{1}{8}+x = \frac{1}{5}

x= \frac{1}{5}- \frac{1}{8}= \frac{8-5}{40}= \frac{3}{40}

so the rate of Katarina is 3/40 (proj per hour)

Now, the rate of Dominik was 1/8 (pr/hr)=5/40 (pr/hr)

In 5 hours Dominik complets 5*5/40=25/40 of the project

Katarina completes 5*3/40=15/40 of the project.
