Find the missing angle
​

Answer:

1.8 m

Step-by-step explanation:

h(T)=-9.8T^2+20T+1

just replace the T with 2

h=-9.8(2^2)+20(2)+1

-9.8×4+40+1=1.8m

1.8m

Answer:

The first 2 statements are true.

Step-by-step explanation:

Answer:

20 ounces

Step-by-step explanation:

For this type of problem it is best to work backwards.

If David has 18, and Charlie gave him 1/2, then Charlie has 36 because 18x2=36. Barbara has 60, because 36/3= 12 and 5x12=60. Then, Amanda has 80 because 60/3=20 and 20x4= 80. But, we need to subtract 60 because the problem asks how many ounces of water does Amanda still have. So, 80- 60(The amount of water she gave to Barbara)=20.

Answer:

20

Step-by-step explanation:

A triangle is obtained when a right rectangular pyramid is sliced by a plane that is perpendicular to the base of the pyramid.

A rectangular pyramid is a three-dimensional object with a rectangle base and a triangular face corresponding to each of the sides of the base.

Cross - sections perpendicular to the base and through the vertex will be triangles. A triangle is obtained as a right rectangular pyramid is sliced by a plane that is perpendicular to the base of the pyramid.

Answer:

9 along one side.

Step-by-step explanation:

This question may be a bit tricky.

The side should mean the entire side, not just along the bottom edge.

The bottom row will have three 1-inch cubes. Three more in a middle row, and three more on top of that. That is a total of nine on that side.

A rotation of 270 would be equal to 630, 990, etc. Adding 360 degrees would result in the same rotation.

Answer:

3

Step-by-step explanation:

2x + 3 = -x + 12

subtract 3 from both sides

2x = - x + 9

add x to both sides

3x = 9

divide by 3

x = 3

Answer:

a) The dimensions of the garden are: 4.5 ft and 5 ft

b) 22.5 ft² of fencing material

c) The most precise name for the shape of the garden is a Rectangle

Step-by-step explanation:

a) Jenna has a garden with coordinate A(2,-1), B(4,3), C(9,3), D(7,-1) where each unit is 1 foot.

What are the dimensions of the garden rounded to the nearest 10th? (Looking for the lengths of the sides)

When we are given coordinates, we find the dimensions using the formula

= √(x2 - x1)² - (y2 - y1)²

(x1 , y1) and (x2 - y2)

For side AB

A(2,-1), B(4,3)

= √(4 - 2)² + (3 - (-1))²

= √2² + 4²

= √4 + 16

= √20 units = √20 feet

= 4.472135955 feet

Approximately = 4.5 feet

For side BC

B(4,3), C(9,3)

= √(9 - 4)² + (3 - 3)²

= √5² + 0²

= √25

= 5 units = 5 feet

For side CD

C(9,3), D(7,-1)

= √(7 - 9)² + (-1 - 3)²

= √(-2)² + -4²

= √4 + 16

= √20 units = √20 feet

= 4.472135955 feet

Approximately = 4.5 feet

For side AD

A(2,-1), D(7,-1)

= √(7 - 2)² + (-1 - (-1))²

= √5² + (-1 + 1)²

= √5² + 0²

= √25

= 5 units = 5 feet

Therefore, the dimensions of the garden are: 4.5ft and 5 ft

b) If Jenna decides to buy fencing for the garden, how much fence material does she need to buy? (Free response)

To buy fencing material for the garden, we have to find the area of the garden

Formula = Length × Width

= 4.5 ft × 5 ft

= 22.5 ft²

Therefore, Jenna needs to buy 22.5 square feet of fencing material.

c) What is the most precise name for the shape of the garden?

From the above calculation, we can see that

Side AB = Side CD = 4.5 ft

Side BC = Side AD = 5 ft

Therefore, the most precise name for the shape of the garden is a Rectangle

Answer:

I'm not sure if the warm up speed is less than the cool down speed.  If it is different than how I did it you just need to swap their positions on the y axis, so the "lumps" or whatever you want to call the shapes will be in opposite positions.  The middle one will stay the same because it is the fastest and in between the two happening.  Also let me know if you can't read any of the labels

Answer:

6

Step-by-step explanation:

The slope m between the 2 points is a measure of the rate of change.

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (3, 8) and (x₂, y₂ ) = (6, 26)

m = [tex]\frac{26-8}{6-3}[/tex] = [tex]\frac{18}{3}[/tex] = 6

Then rate of change is 6
