F ( x ) = x 2 + 6 x and g ( x ) = x − 8 , calculate. f ( g ( − 5 ) ) =
BlackZzzverrR [31]

\qquad\qquad\huge\underline{{\sf Answer}}

Let's solve ~

First we have to calculate g (-5) :

\qquad \tt \dashrightarrow \:x - 8

\qquad \tt \dashrightarrow \: - 5 - 8

\qquad \tt \dashrightarrow \: - 13

Now, let's find f (g (-5)) :

\qquad \tt \dashrightarrow \: {x}^{2}  + 6x

\qquad \tt \dashrightarrow \:( - 13) {}^{2}  + (6 \times  - 13)

\qquad \tt \dashrightarrow \:169 + ( - 78)

\qquad \tt \dashrightarrow \:169 - 78

\qquad \tt \dashrightarrow \:91

What is the value of A? <br>5<br>5 1/3<br>6 2/3<br>7
Anna35 [415]
This is a neat little question. I don't think I've seen it before.
Step one 
=======
Find c
3^2 + 4^2 = c^2
9 + 16 = c^2
c^2 = 25
c = 5

Step 2
====
Set up your first equation for b^2
a^2 + 4^2 = b^2 from triangle XWY

Step 3
=====
Set up your second equation for b^2
25 +b^2 = (a + 3)^2 from triangle XWZ

Step 4
=====
Put the results of Step 2 into step 3 and solve
25 + a^2 + 16 = (a + 3)^2 Collect the like terms on the left.
41 + a^2 = (a + 3)^2 Expand the brackets on the right
41 + a^2 = a^2 + 6a + 9 Transfer the 9 to the left.
32 + a^2 = a^2 + 6a Subtract a^2 from both sides.
6a = 32 Divide by 6
a = 32 / 6
a = 5 2/6
a = 5 1/3

An entrepreneur buys some microscopes. Each one cost $200 and resells online for $526. What is the mark-up percentage?
Dafna11 [192]

Answer:

326

Step-by-step explanation:

Given: Microscopes. Each one costs $200 and resells online for $526.

To find: What is the mark-up percentage?

Solution: Simply take the sales price minus the unit cost, and divide that number by the unit cost. Then, multiply by 100 to determine the markup percentage.

526 - 200 = 326

Net Profit Margin = 61.98%

Net Profit = $326.00

Profit Percentage = 163.00%
