Woops, new to this. As I was trying to say, it is actually really simple if you try to figure it out. The answer is 42.

So easy

so driscoll has 9 reports to grade and each page has 6 pages.

just multiply 9 and 6 which gives you your answer 54.

so out of 54, he has graded only 12 pages which means that you need to subtract.

54-12=42

driscoll has 42 pages left to grade.

you can recheck your answer by adding 42 ans 12 which gives your answer as 54. so yup our answer is right.

Can someone explain how to do this please?
Rufina [12.5K]

for the columns where is less than or equal zero, use the first line of the function to calculate the value of f(x)

{ ( \frac{1}{3} ) }^{ - 2} - 1  = 9 - 1 = 8 \\ { ( \frac{1}{3} ) }^{ - 1}  - 1 = 3 - 1 = 2 \\ { ( \frac{1}{3} ) }^{ 0} - 1  = 1 - 1 = 0

for every x greater than zero, use the second line to determine the value

{3}^{1}  - 2 = 3 - 2 = 1 \\ {3}^{2}  - 2 = 9 - 2 = 7

hope this helps and gives some insight what to do.

if there are open questions left, feel free to ask them in the comments

have a beautiful day

What is the value of x in the triangle?
yulyashka [42]
<h3>Answer: C) x = 13</h3>

====================================================

Work Shown:

We have a right triangle with legs a = 5 and b = 12. The hypotenuse is c = x which is unknown for now.

Use the pythagorean theorem to find x.

a^2 + b^2 = c^2

5^2 + 12^2 = x^2

25 + 144 = x^2

169 = x^2

x^2 = 169

x = sqrt(169)  .... apply the square root to both sides

x = 13

Using the Pythagorean theorem, if the hypotenuse is 17 feet long, and side a is 15 feet long. What is the missing length of side
Shtirlitz [24]

Answer:

The missing side is 8 ft long

Step-by-step explanation:

According to Pythagoras theorem <em> "It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides"</em>

mathematically it is stated as

c^2= a^2+b^2\\\\c=\sqrt{a^2+b^2}

Given that

c, hypotenuse= 17 ft

a = 15 ft

b= ?

Applying the Pythagoras theorem formula by inserting our given parameters and solving for b we have

17^2= 15^2+b^2

Making b subject of formula we have

b^2= 17^2-15^2\\\\b^2= 289-225\\\\b^2= 64\\\\

Square root both sides we have

b= \sqrt{64} \\\\b= 8

Hence the missing side is 8 ft long
