Answer:

B

Step-by-step explanation:

Your first instinct is correct. Plus, it says GAIN ==> +. Not LOSS ==> -.

Answer:

Step-by-step explanation:

Choice B is correct. It’s given that the helicopter’s initial height is 40 feet above the ground and that when the helicopter’s altitude begins to increase, it increases at a rate of 21 feet per second. Therefore, the altitude gain t seconds after the helicopter begins rising is represented by the expression 21 t. Adding this expression to the helicopter’s initial height gives the helicopter’s altitude above the ground y, in feet, t seconds after the helicopter begins to gain altitude:  y equals, 40 plus 21 t.

May you send the picture of the provided graph number?

Step-by-step explanation:

Unable to answer without photo.

The equation [tex]y = 2x + 5[/tex] can be used to model the cost, y, that Johnny pays to use the online ordering service for his company, depending on the number of orders placed, x.

The constant term in the equation, 5, represents the fixed monthly fee Johnny has to pay regardless of the number of orders he places. The coefficient of x, 2, represents the additional cost per order. To graph this equation, we can plot points on a coordinate plane using different values of x and solve for y. Let's consider a few options: When x = 0 (no orders placed), [tex]y = 2(0) + 5 = 5[/tex] . So the point (0, 5) is on the graph. When x = 1 (one order placed), [tex]y = 2(1) + 5 = 7[/tex] . Therefore, the point (1, 7) is on the graph.

Suppose x = 3 (three orders placed), [tex]y = 2(3) + 5 = 11.[/tex]  Hence, the point (3, 11) lies on the graph. Once we have a few points, we can connect them with a straight line. The graph will show that as the number of orders placed increases, the cost Johnny pays to use the online ordering service will also increase at a constant rate of $2 per order.

The line will have a positive slope and intercept the y-axis at (0, 5). In summary, the graph of the equation [tex]y = 2x + 5[/tex]  represents the cost Johnny pays to use the online ordering service, with a fixed monthly fee of $5 and an additional charge of $2 per order placed.

Answer:

[tex]54[/tex] feet

Step-by-step explanation:

Length of the flower bed [tex]=15[/tex] feet.

Width of the flower bed is [tex]\frac{4}{5}[/tex] the length.

So, width [tex]=\frac{4}{5}\times 15=4\times 3=12[/tex] feet.

To find the length of the fencing, we need to find the perimeter of the flower bed.

Perimeter of a rectangle [tex]=2(\textrm{length} + \textrm{width})[/tex]

So, perimeter of the flower bed [tex]=2(15+12)=2\times 27 = 54[/tex] feet.

Hence, [tex]54[/tex] feet of fencing is required for the flower bed.

Answer:

Its C i just took the test and got this right!!!

Step-by-step explanation:

The side 3 cm, 4 cm, and 5 cm will satisfy the Pythagoras equation. Then the correct option is C.

The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

The Pythagoras theorem formula is given as

H² = P² + B²

The converse of the Pythagorean theorem using side lengths chosen from 2 cm, 3 cm, 4 cm, and 5 cm.

The side 3 cm, 4 cm, and 5 cm will satisfy the Pythagoras equation.

5² = 4² + 3²

25 = 16 + 9

25 = 25

The side 3 cm and 4 cm is normal to each other.

Then the correct option is C.

Answer:

Scale factor = 7

Step-by-step explanation:

Dilation with scale factor to map HEFG to DABC will be,

Scale factor = [tex]\frac{\text{Dimension of Image DABC}}{\text{Dimension of preimage HEFG}}[/tex]

                    = [tex]\frac{\text{Length of CD}}{\text{Length of GH}}[/tex]

Length of CD = Distance between two points C(0, -7) and D(-7, 0)

                       = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

                       = [tex]\sqrt{(-7-0)^2+(0+7)^2}[/tex]

                       = [tex]\sqrt{98}[/tex]

                       = [tex]7\sqrt{2}[/tex]

Length of GH = Distance between G(0, -1) and H(-1, 0)

                       = [tex]\sqrt{(-1-0)^2+(0+1)^2}[/tex]

                       = [tex]\sqrt{2}[/tex]

Scale factor = [tex]\frac{7\sqrt{2} }{\sqrt{2} }[/tex]

Perimeter formula is:

Given:

Substitute and solve for x:

Then find the values of l and w:

Answer:

length is 28m and width is 15m

Step-by-step explanation:

Let length = l

and width = b

According to the given condition,

l = 2b -2

Now,

Perimeter of a rectangle, P = 2(l+b)

According to question

P = 86

2(l+b) = 86

l + b = 43

2b -2 + b = 43

3b = 45

b =15

Therefore, l = 2x15 -2 = 28

So length is 28m and width is 15m
