I am confused on number 15, the instructions are at - 1

Answer 1
Answer: You don't have #15 included.  If you meant to put #25, I already answered that.  Here is the solution again though.

#25 is fairly simple.  Plug in -4 and 3 into the equation, and the extraneous root will be the one that does not work.
√(12-(-4)) = √(16) = \frac{+}{}4
Extraneous root in this case is positive four since +4≠-4
√(12-3) = √(9) = \frac{+}{}3
In this case it's negative 3, since -3≠3

Suppose that you want to model the height of a rider on a Ferris wheel as a function of time. The amplitude of the function you use as a model should be equal to which of the following?A) the area of the Ferris wheel
B) the circumference of the Ferris wheel
C) the diameter of the Ferris wheel
D) the radius of the Ferris wheel

Answers

D
The maximum vertical displacement of the rider from the center will be when he is at the top or bottom of the Ferris wheel. The distance from the center to the top (or bottom) of the Ferris is its radius.

Write "252 miles per 8 gallons " as a rate in simplest form

Answers

Hi there! 252 miles per gallon would be 252 miles/8 gallons. The GCF of 252 and 8 is 4 so we are going to divide by 4. 252÷4=63 and 8÷4=2. In this case, we have a fraction of 63/2.

Answer:

Rate per gallon in simplest form is, (63)/(2)

Step-by-step explanation:

Unit rates defined as the rates are expressed as a quantity of 1, such as 5 feet per second or 6 miles per hour, they are called unit rates.

Given the statement: 252 miles per 8 gallons.

⇒ Number of miles = 252

and number of gallons = 8

Unit rate per gallons = \frac{\text{Number of miles}}{\text{Number of gallons}}=(252)/(8)

Divide numerator and denominator both by 4 we get;

Unit rate per gallons = ((252)/(4) )/((8)/(4)) = (63)/(2)

Therefore,  "252 miles per 8 gallons " as a rate in simplest form is, (63)/(2)

Enter the plan width for the rectangular room. Round your answer to the nearest tenth.plan length:
4 in.
actual width:
18 ft
actual length: 16 ft


The plan width is
in.

Answers

Answer:

4.5 inches

Step-by-step explanation:

Given: plan length = 4 inches, actual width = 18 feet, actual length = 16 feet

To find: plan width

Solution:

1 feet = 12 inches

Plan length = 4 inches

Actual width = 18 feet= 18× 12 = 216 inches

Actual length = 16 feet = 16× 12 = 192 inches  

Plan length/plan width  =  actual length/actual width

(4)/(plan\,\,width)=(192)/(216)\n  plan\,\,width=(216)/(192)(4)=4.5\,\,inches
