6.Kelly has been training to run across the country. On the first day, she ran 4 miles, the
second day, she ran 12 miles, and the third day, she ran 36 miles.
a) Write an equation that models Kelly's situation?

Answers

Answer:

D= d₁ + d₂ + d₃   : where D is total distance covered in the training.

Step-by-step explanation:

Let this equation model the total distance covered in the training.

Let the total distance covered in the training to be: -------D

Let the distance covered in 1st day be ----------d₁ = 4 miles

Let the distance covered in 2nd day be ----------d₂= 12 miles

Let the distance covered in 3rd day be ----------d₃ = 36 miles

D= d₁ + d₂ + d₃

D= 4 + 12 + 36

D= 52 miles

Joe's cell phone cost him $21 per month plus $3 for every 1GB downloaded. What is the limit to the number of GBs he can download to stay within his monthly budget of $30?

Answers

Answer:

I'll help you with this so reflections is not hard.

For reflect over x-axis you need to switch the sign on Y. formula for points like this is (x,y). An example is reflect (2,4) over the x-axis. you just change the sign of y making the answer (2,-4).

For reflect over y-axis you change the sign of X.For example reflect over the y-axis (3,7) all you have to do is change the sign of X which leaves you with the answer of (-3,7).

sign is basically + or - if need to know.

I hope this helps you in the long run.

If the shortest side of a right triangle is 19, what are the lengths of the other TWO sides
that makes the side lengths a Pythagorean triple? HELP ASAP PLZ

Answers

Answer:

180 and 181

Step-by-step explanation:

A pythagorean triple basically refers to numbers that satisfies the pythagorean theorem. This theorem states that the square of the hypotenus (a) of a right angle triangle is equal to the sum of the squares of the other two sides (b and c).

That is;

a² = b² + c²

If the shortest side is 19, the other two sides are 180 and 181.

The hypotenus is the longest side of the right angle triangle.

Check:

181 = 180 + 19

181² = 180² + 19²

32761 = 32400 + 361

32761 = 32761

Write an exponential function to model the following situation.
A population of 130,000 grows 3% per year for 16 years.
How much will the popluation be after 16 years?
Write an exponential function in terms of x.
y=10

Answers

Answer:

y = 130,000(1.03)ˣ

Step-by-step explanation:

The general form of an exponetial function is y = abˣ, where a is the initial value (when x = 0), and b is the multiplier (the growth or decay factor). Here, we start with a population of 130,000, so our initial value a = 130,000. A growth of 3% each year represents a growth factor of 1.03, so after x years, the population y should be y = 130,000(1.03)ˣ.

The exponential function in terms of x and y is y = 130,000(1.03)ˣ

What is an exponential function ?

The exponential function is a mathematical function denoted by

y = abˣ

where a is the initial value (when x = 0)

and b is the multiplier (the growth or decay factor).

population starts from 130,000, so

Initial value a = 130,000.

A growth of 3% each year represents a growth factor of 1.03,

so after x years, the population y should be

y = 130,000(1.03)ˣ

Therefore , The exponential function in terms of x and y is y = 130,000(1.03)ˣ

Trisha has $100 to spend on presents for 4 of her friends. She wants to spend the same amount on each friend. How much money can she spend on each friend (x)?


*Choose the inequality that best matches this scenario.

a. 4+x ≤ 100

b. 4x ≤ 100

c. x ÷ 100 ≥ 4

d. 100 - x ≥ 4

Answers

Answer:

B

Step-by-step explanation:

Trisha has $100. So she has to spend less than $100 or exactly 100 on her friends. The sign to represent this is ≤ ( the less than or equal to sign )

so if she has 4 friends and wants to spend x on each friend, she would spend a total of 4x on her 4 friends.

Remember that she has to spend less than or equal to $100. The equation to represent this is 4x ≤ 100
