QUESTION POSTED AT 18/01/2020 - 07:20 AM

Answered by admin AT 18/01/2020 - 07:20 AM

The answer is (2,9).

This is because we can increment X by 1, giving us X=2. We can then do:
f(2)=25•(3/5)^2
Which equals:
f(2)=25•(3^2/5^2) because (a/b)^c = a^c/b^c.

We can then calculate the fraction in a simplified form:
f(2)=25•(9/25)=225/25
which fully simplified gives us
f(2)=9/1=9

QUESTION POSTED AT 17/02/2020 - 12:36 PM

The difference between a number and 21 1/2 is no more than 14 1/4

Answer: Hello!

ni this problem i consider that the notation 21 1/2 is equivalent to 21 + 1/2 = 21.5

our phrase is:

"The difference between a number and 21 1/2 is no more than 14 1/4"

we can break it into two parts to make it easier.

"The difference between a number and 21 1/2"

this is a subtraction, here you are subtracting 21 1/2 to a number, let's call this number x, then we can write this as:

x - 21 + 1/2

or x - 21.5

the second part says: "is no more than 14 1/4"

then the thing that we got before, is less or equal than 14 1/4 (or 14.25), this is

x - 21.5 ≤ 14.25

now you can add the same number in both sides of the inequality and it remains the same, then you can add 21.5 to both sides and:

x - 21.5 + 21.5 ≤ 14.25 + 21.5

x ≤ 35.75

Craig used the diagram to compute the distance from Ferris to Dunlap to Butte. How much shorter is the distance directly from Ferris to Butte than the distance Craig found? (1 point) 14 mi 28 mi 70 mi 98 mi

So you need to do 3 things.
First, find craigs distance by adding up the sides.

1)
C = 42 + 56 = 98
Then, find the direct distance, D. This can be done using Pythg. Theorem.
2)
D = √(42²+56²) = 70

3) Now just find the difference.

A = 98 - 70 = 28

A = 28!

Joe Fleet can jog at the rate of 8 mph. Ron Pack can hike carrying camping equipment at the rate of 4 mph. They leave from opposite ends of a 44-mile trail at the same time. How far does each travel if Ron has 15 minutes to set up camp before Joe arrives?

The solution to the problem is as follows:
Joe's travel time in hours (x): 

4(x - 0.25) + 8x = 44 

4x - 1 + 8x = 44 
12x = 45 
x = 3.75 

Distance covered by Ron: 

= 4(3.75 - 0.25) 

= 4(3.5) 
= 14 

Distance covered by Joe: 

= 8(3.75) 

= 30 

Answer: Ron, 14 miles; Joe, 30 miles

Which of the following statements is true? a.Reanna's answer is correct. b.Reanna should have multiplied 6 centimeters by the vertical height. c.Reanna should have multiplied her answer by. d.Reanna should have added all of the sides together.

Answer:

The correct option is b.

Step-by-step explanation:

The area of parallelogram is

A=b\times h

Where, b is base and h is vertical height.

It is given that the lengths of the sides are 6 cm and 4 cm.

To find area of parallelogram Reanna multiplied 6 centimeters by 4 centimeters. Her answer was 24 cm 2. Which is not correct.

Reanna should have multiplied 6 centimeters by the vertical height.

Therefore option b is correct.

14.A company employee has to print 3145 pages, and the company's printer prints 85 pages per minute. The function f(x)=−85x+3145f(x)=−85x+3145 represents the number of unprinted pages x minutes after the printing begins. What is the practical domain of function f? all whole numbers from 0 to 37 all real numbers from 0 to 37 all real numbers from 0 to 3145 all multiples of 85 between 0 and 3145

F(x) = -85x + 3145...the domain is going to be the x value while the range is the f(x) value.

answer is going to be all whole numbers from 0 to 37

notice if u sub in 37 for x.....
f(37) = -85(37) + 3145
f(37) = - 3145 + 3145
f(37) = 0...that means after 37 minutes, there are no un-printed pages...all the pages have been printed. So ur answer would be greater then 0, but less then or equal to 37.....and they have to be whole numbers.....they cant be all real number because that includes irrational numbers.

So the  goal here is to find the value of "w". The first thing you must do is transpose the number 9 to the side of -7 and it would look like this, 4w = -7 - 9. Change the positive sign of the number 9 to negative when you transpose. Then, the equation will be simplified and it will look like this, 4w = -16. Then lastly, to get the value of "w", you must divide the equation to 4 and it will be like this, 
4w = -16    so you will get the answer w = -4. I hope this helps you
