Use the mapping (x+3, y-5), for the transformation of triangle ABC with vertices A(-2, -4), B(0, 0), and C(1, -3), find the coordinates of the new triangle A’B’C’ . You must show all your work.

Answers

Well there’s no picture for me to go off of so I will give you an easy enough explanation of what I think this is supposed to be.

You’re basically going to go left side three points and down five for every point on the graph (aka ABC) and once you do that label the abc marks with an apostrophe like so; A’B’C’ for every time you change places (I think this is mostly accurate so good luck)

A car rental agency charges $75 per day, which includes 100 miles. For each mile over 100 miles, there is an additional cost of $0.35 per mile. Write an equation relating
m, the number of miles driven, if the total cost for a one-day rental was $131.

Part A. Write an equation relating m , the number of miles driven, if the total cost for a one-day rental was $131.

Part B. Find the solution to the equation you created in the previous question and explain what the solution means in this situation.

Answers

The number of miles, m driven if the total cost for a one-day rental was $131 is; m = 160

According to the question;

The agency charges $75 per day, which includes 100 miles.

Additionally, the agency charges $0.35 per mile for each additional mile;

a) The equation relating m , the number of miles driven, if the total cost for a one-day rental was $131 is therefore;

$0.35m + $75 = $131.

b) To find the solution to the equation;

$0.35m = $131 - $75

$0.35m = $56

m = $56/$0.35

m = 160.

The number of miles, m driven if the total cost for a one-day rental was $131 is; m = 160.

How might the crisis in biodiversity lead to a food crisis for humans?

Answers

Answer:

Hi and heres your answer!

Step-by-step explanation:

The crisis of biodiversity will lead to a food crisis for humans because:

1.No varieties in certain foods like plants and animals that are healthy

2.The Less food there is,more animals go extinct which means humans will go extinct too.

and finally 3: Without certain types of species like the bee, humans have no chance of survival (since bees pollinate flowers,fruits,and plants which could be used for human consumption and medicine)

The surface area in square meters of the human body can be found using the expression √hm/3600 where h is the height in centimeters and m is the mass in kilograms. find the surface area of a 15-year-old boy with a height of 183 centimeters and a mass of 74 kilograms. (√ = square root)

Answers

The surface area is a function of height and mass of the body

The surface area of the 15-year-old boy is 1.92 cm square

The given parameter is:

[tex]A = \sqrt\frac{{hm}}{3600}[/tex]

When h = 183 cm ad m = 74 kg

The function becomes

[tex]A = \sqrt{\frac{180 \times 74}{3600}[/tex]

[tex]A = \sqrt{\frac{13320}{3600}[/tex]

[tex]A = \sqrt{3.7}[/tex]

[tex]A = 1.92[/tex]

Hence, the surface area of the 15-year-old boy is 1.92 cm square

To win a trivia game, Nevan must score 90 points. Each correct
answer is worth 1 3/4 points, and each incorrect answer is worth
- 1/4 points. If he gets 58 questions correct and 22 questions incorrect, does Nevan win? How many points does he score?

Answers

Answer:

Nevan does not win

He scored 74 points

Step-by-step explanation:

First, find how many points he gets from 58 correct questions:

Multiply 1 3/4 by 58:

58(1.75)

= 101.5

Then, find how many points he loses from 22 incorrect questions:

Multiply -1 1/4 by 22:

22(-1.25)

= -27.5

Then, subtract 27.5 from 101.5 to find how many points he scored:

101.5 - 27.5

= 74

Since he needed 90 points to win, he did not win because he only got 74.

Given g(x)=-2x-1g(x)=−2x−1, find g(-4)g(−4)

Answers

Answer:

Step-by-step explanation:

The function f is defined by g(x) = -2x-1. so the function defined as g (-4) will be equal to g (-4) = 7.

What is a function?

Function is a type of relation, or rule, that maps one input to specific single output.

The function f is defined by g(x)=−2x−1

We need to find the function defined as g(-4).

Then substitute;

g(x)=−2x−1

g(-4 ) =−2 (-4) − 1

g(-4 ) = 8 -1

g(-4 ) = 7

Therefore, The function f is defined by g(x) = -2x-1. so the function defined as g (-4) will be equal to g (-4) = 7.

An ostrich was 960meters east of its nest. It ran west at a constant velocity for 160seconds. In that time, it ran halfway to its nest. What was its velocity?

Answers

Answer is 3 m/s.

Step-by-step explanation:-

The ostrich ran at a constant velocity, so it's velocity was :

[tex]velocity = \frac{distance}{time} [/tex]

It is said that the bird ran for 160 seconds and it made it half-way to its nest, so the distance was :

[tex]distance = \frac{960 \: metres}{time} [/tex]

[tex]distance = 480 \: metres[/tex]

And the velocity is :-

[tex]velocity = \frac{480 \: metres}{160 \: seconds} [/tex]

[tex]velocity = 3 \: m/s[/tex]

Therefore, the ostrich ran at a velocity of 3 m/s .
