The student in Ms. Durham’s class create a dot plot to show the heights of the robots they built. How many robots were built?

Answer:

12.56 in²

Step-by-step explanation:

Area = πr²

Substitute for pi.

A = 3.14 × r²

The diameter is 4. We divide the diameter by 2 to get the radius.

4 ÷ 2 = 2

Substitute for the radius.

A = 3.14 × 2²

Solve

A = 3.14 × 4 = 12.56 in²

Answer:

e= -1/2

Step-by-step explanation:

(4/3) +5/3 = (-6e - 5/3) +5/3

4/3 +5/3  = -6e

(3)/-6 = (-6e)/-6

e = -1/2

Answer:

Given the equation y = -16t^2 + 96t + 3, we know a = -16, b = 96, c = 3.

Let's solve for h in this problem.  

h = -b/2a

h = -(96) / 2(-16)

h = -96 / -32

h = 3 seconds

Now let's add t=3 to our equation:

y = -16t^2 + 96t + 3

y = -16*(3)^2 + 96*(3)+ 3

y = -144 + 288 + 3

We now know that the vertex is (3,147), which means that the ball's maximum height is 147 feet.

Answer:

Step-by-step explanation:

Find the height at   h(0)   and   h(1)

h(0) = 3 ft

h(1) = -16 + 32 + 3 = 19 ft

It takes 1 second to go from 3 feet to 19 feet

  (19-3) ft / 1 sec = 16 ft/sec

∠1 and ∠4 are corresponding angles has the same shape and size. ∠1 and ∠3 are diagonal from each other and ∠15 and ∠9 make a straight line.

Parallel lines represent coplanar endless straight lines in geometry that never intersect. Within a single three-dimensional space, parallel planes are any planes that never cross. Curves with a predetermined minimum distance between them and no contact or intersection are said to be parallel.

Euclid's parallel postulate deals with parallel lines. Euclidean geometry is indeed a particular example of this sort of geometry, and parallelism is essentially a feature of affine geometries.

∠1 and ∠4 are corresponding angles has the same shape and size

∠1 and ∠3 are diagonal from each other

∠15 and ∠9 make a straight line

Therefore, ∠1 and ∠4 are corresponding angles has the same shape and size. ∠1 and ∠3 are diagonal from each other and ∠15 and ∠9 make a straight line.

Answer:

150Ft^2

Step-by-step explanation:

The area of a parallelogram is A=BH where B is base length and H is height. I'm not sure why there is information about a triangular base, maybe an illustration would help. But with the information provided, the base times  height is equal to 150 Ft^2. Check out the Kahn Academy video for a better explanation  

Answer:

31.5p+955.5=1428

p=15

Step-by-step explanation:

31.5p+955.5=1428

−955.5 = −955.5

Subtract 955.5 from both sides

31.5p=

\,\,472.5

472.5

31.5

31.5p

​ =

31.5

472.5

​Divide both sides by 31.5

p=15

​

The number of equation players the team can bring 15 players to the tournament.

Let's break down the information given in the problem:

Total amount raised: $1428

Cost of renting a bus: $955.50

Budgeted amount per player for meals: $31.50

To determine the number of players the team can bring to the tournament (represented by "p").

The total cost for the bus and meals calculated as follows:

Total Cost = Cost of Bus + (Cost per Player × Number of Players)

Using the given values, we can write this as an equation:

Total Cost = $955.50 + ($31.50 × p)

Now we can set up the equation using the total amount raised:

Total Amount Raised = Total Cost

Substitute the values:

$1428 = $955.50 + ($31.50 × p)

Now, let's solve for "p":

$1428 - $955.50 = $31.50× p

$472.50 = $31.50 × p

To isolate "p," divide both sides by $31.50:

p = $472.50 / $31.50

p = 15

Because you need to half the diameter to fit it into the formula. So you would do 7 divided by 2 to get the radius which is 3.5. Then you do 3.5 x pi

Answer: (1/2, -1)

Step-by-step explanation: The coordinates of point S can be found using the midpoint formula for the hypotenuse RT, since S is the midpoint of RT. The midpoint formula is:

Midpoint of RT = ( (x1 + x2)/2 , (y1 + y2)/2 )

Using the coordinates of R and T, we get:

Midpoint of RT = ( (-1 + 2)/2 , (1 - 3)/2 )

= (1/2, -1)

Therefore, the location of point S is (1/2, -1).

Answer:

Initially, as x increases, y is constant.

Afterward, the slope of the graph of the function equals 2 for all x between x = 3 and x = 5.

The slope of the graph equals -1 for x between x = 5 and x = 9.

The greatest value of y is y = 4, and it occurs when x = 5.

Step-by-step explanation:

Initially, the graph of the function is flat. The quantity y remains constant as x increases from x = 0 to x = 3. The linear equation that corresponds to the function in that region is y = 0. The slope is m = 0 because the graph is a horizontal line. The graph of the function starts to increase starting at x = 3. The slope, rise/run, once we solve it, is equal to 2 for when x is between 3 and 5. After x = 5, y starts to decrease as x increases. The slope of the graph between x = 5 and x = 9 is -1. The maximum value of y occurs at the top of the bump in the graph. The coordinates of the top of the bump are (5,4). Therefore, the maximum value is y = 4, and it occurs when x = 5.

8x7=56ft

6x2=12ft

2x1÷2=1ft

56+12+1=69ft²

Answer:

Option A, 69 square feet

Step-by-step explanation:

Step 1:  Determine the area of the rectangle

[tex]A = l * w[/tex]

[tex]A = 7\ ft * 8\ ft[/tex]

[tex]A = 56\ ft^2[/tex]

Step 2:  Determine the area of the second rectangle

[tex]A = l * w[/tex]

[tex]A = 6\ ft * 2\ ft[/tex]

[tex]A = 12\ ft^2[/tex]

Step 3:  Determine the area of the triangle

[tex]A = \frac{h * b}{2}[/tex]

[tex]A = \frac{(7\ ft - 6\ ft)*2\ ft}{2}[/tex]

[tex]A = \frac{1\ ft * 2\ ft}{2}[/tex]

[tex]A = \frac{2\ ft^2}{2}[/tex]

[tex]A = 1\ ft^2[/tex]
