**WILL GIVE MEDAL!!!**A car traveling on a highway is 60 miles away from home after 1 hour, and is 300 miles away from home after 5 hours. What is the rate of change of the car’s distance over time?

a. 1/60 mph
b. 15/2 mph
c. 55mph
d. 60 mph

Answers

Answer 1
Answer: If the car is traveling 60mph and is 300 miles away after 5 hours, the rate of change here is to divide 5 by 300. The answer is 60 (D). The problem here would look like 300/5=60. So the rate of change of the car's distance over time would be 60.

True or False: Certain irrational numbers can be written as fractions

Answers

Answer:

False

Step-by-step explanation:

It can be written as a decimal but not a fraction cause it will always terminate or repeat

Final answer:

The claim that certain irrational numbers can be written as fractions is false. Irrational numbers cannot be expressed as fractions while rational numbers can be. The statement is false.

Explanation:

By definition, irrational numbers cannot be written as fractions. Irrational numbers are numbers that, when time in a decimal form, neither terminate nor repeat. Examples of irrational numbers include sqrt(2) and π. On the other hand, fractions or rational numbers always terminate or repeat when written as a decimal.

I completed this question on USA Test Prep and got this answer

you are standing, on the horizontal ground, __ feet from the base of a cliff. Admiring your surroundings, you nite that the angle of elevation to the top of the cliff to be __ degrees. If realistic limits are imposed on your choices, what would be a reasonable distance from the cliff? What would be a reasonable angle if elevation? Explain.

Answers

If realistic limits are imposed on the choices I would go with 1000 ft. For the angle of elevation I would chose 34°. This because as we know an angle of elevation is the angle between the observer's’ line of sight and a horizontal line when the observer looks upward.



If you wanted to find the height of the cliff you would use the following:



Tan34 = x/1000

x = tan(34)*1000

x = 674.51 ft.

Find the balance in the account. $700 principal earning 5%, compounded monthly, after 9 years

Answers

Answer: The balance in the account after 9 years is $1085.93.

Step-by-step explanation:

Since we have given that

Principal amount = $700

Rate of interest = 5%

Number of years = 9

Since we have mentioned to use "Compound Interest " method:

As we know the formula for above i.e.

A=P(1+(r)/(100))^n\n\nA=700(1+(5)/(100))^9\n\nA=\$1085.93

Hence, the balance in the account after 9 years is $1085.93.
A=700×(1+0.05÷12)^(12×9)
A=1,096.79
