Answer:

42

Step-by-step explanation:

Divide it into 2 parts: 1*12 and (12*5)/2

1*12 = 12

(12*5)/2 = 60/2 = 30

30 + 12 = 42

It’s 51. You just make a rectangle and a triangle, and add.

Ok, I'm going to do this question again. Can someone PLEASE help me. This is due and I need to get it done. Answer it right please.

Answers

The independent variable would be the one that could stand alone. So which one makes more sense? The amount of trips depends on how many buckets there are or the amount of buckets depends on the amount of trips?

Since the amount of trips DEPENDS on the amount of buckets... the amount of trips is the dependent and the buckets is the independent. so since there are 2 buckets carried up to hill for 1 trip, the first row on the table should look like this

2 1 (2,1)

So how many buckets would be on the hill after the second trip?

Well there are 2 more and 2 + 2 is 4. 2 trips = 4 buckets. So the next row would look like this

4. 2. (4,2)

Then u just keep going. Hint: Independent variable is counting by twos and dependent variable is counting by one's.

Then you graph the ordered pairs.

Hope this helped :)

Roller Coaster Crew

Ray and Kelsey have summer internships at an engineering firm. As part of their internship, they get to assist in the planning of a brand new roller coaster. For this assignment, you help Ray and Kelsey as they tackle the math behind some simple curves in the coaster's track.

Part A

The first part of Ray and Kelsey's roller coaster is a curved pattern that can be represented by a polynomial function.

1. Ray and Kelsey are working to graph a third-degree polynomial function that represents the first pattern in the coaster plan. Ray says the third-degree polynomial has four intercepts. Kelsey argues the function can have as many as three zeros only. Is there a way for the both of them to be correct? Explain your answer.

2. Kelsey has a list of possible functions. Pick one of the g(x) functions below and then describe to Kelsey the key features of g(x), including the end behavior, y-intercept, and zeros.
g(x) = (x + 2)(x − 1)(x − 2)
g(x) = (x + 3)(x + 2)(x − 3)
g(x) = (x + 2)(x − 2)(x − 3)
g(x) = (x + 5)(x + 2)(x − 5)
g(x) = (x + 7)(x + 1)(x − 1)

3. Create a graph of the polynomial function you selected from Question 2.

Nicole is half as old as Donald. The sum of their ages is 72.

How old is Nicole, in years?

Answers

Your gonna divide 72 by 2 so therefore you get 36
So that equals to Nicole’s age

Answer:

24 years

Step-by-step explanation:

let Donald's age be x

then Nicole's age would be 1/2 * x = x/2

now, x + x/2 = 72

3x/2 = 72

3x = 72*2

x = 144/3 = 48

Donald's age is 48, so Nicole's age is 1/2 * 48 = 24 years.

Solve the equations. Make conclusion. 3|x+12|=6

*Please put down the steps also.*

Answers

3 | x+12 |=6
Start by distributing 3 to both x and 12
You get 3x+36=6
Subtract 36 from both sides
You then get 3x=-30
Divide 3 from both sides getting
x= -10

Answer: 36.84

(lmk if this isnt right)

Step-by-step explanation:

To find the perimeter of the rectangle:

3+3+3+3+3+3=18

or

3(6)=18

To find the diameter of the circle:

12-(3+3)

12-6=6

You can combine the 2 half circles to make 1 full circle since they both have the same diameter. Use the circumference formula to solve.

C=πd

Substitute

C=3.14(6)

Multiply

C=18.84

Add the perimeter of the rectangle and the circumference of the circle.

18+18.84=36.84

Answer:

5/8 cm cubed

Step-by-step explanation:

When you calculate volume, you are essentially seeing how much space is inside the given item. To do this, you can multiply all three dimensions(length, width, and height).

Width: 1/3 cm; Length: 3/4 cm, Height: 5/2 cm

When you multiply these you get 15/24 cm cubed. This simplifies to 5/8 cm cubed.
