The value of equation describes the line graphed is,

⇒ y = -1/5x - 4

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (0, -4) and (5, -5).

Now,

Since, The equation of line passes through the points (0, -4) and (5, -5).

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (- 5 - (-4)) / (5 - 0)

m = - 1 / 5

Thus, The equation of line with slope - 1/5 is,

⇒ y - (-4) = -1/5 (x - 0)

⇒ y + 4 = -1/5x

⇒ y = -1/5x - 4

Therefore, The equation of line passes through the points (0, -4) and

(5, -5). will be;

⇒ y = -1/5x - 4

a circular garden has a diameter of 6 yards.What is the area of the garden. Use 3.14

Answers

Answer:

28.26 yd^2

Step-by-step explanation:

A = 3.14 • r^2

Radius is half of the diameter, so 3.

A = 3.14 • 3^2

A = 3.15 • 9

A = 28.26 yd^2

Answer:  The area of the garden is 28.26

Step-by-step explanation:

1. Divide the diameter in half, that gives you the radius, in this case: 3

2. Use the formula for finding the area with the radius: A= π r², and use 3.14 instead of pi. Multiply 3.14 by 3²

3. You should get 28.26 as your answer.

How many seconds will elapse between seeing lightning and hearing the thunder if the lightning strikes 5.0 mi (26,400 ft) away and the air temperature is 83.6°F?

Answers

Answer:

Time taken = 23.10 sec (Approx)

Step-by-step explanation:

Given:

Distance of lighting = 5 mi = 26,400 ft

Air temperature =83.6°F  = 28.67°FC

Computation:

Speed of the sound

V = 331 + 0.61 × T

V = 331 + 0.6 × 28.67

V = 348.202 m/s

Distance = 5 mi = 8,046.72 m

Time taken =  Distance / Speed

Time taken =  8,046.72 / 348.202

Time taken = 23.10 sec (Approx)

It will be compressed vertically

Step-by-step explanation:

y = Cf(x) 0 < C < 1 compresses it in the y-direction

Since we are multiplying by 1/4 it will compress it by 1/4 in the y direction

Answer:

When you multiply the whole function by a constant, which can be identified as "C", you can have the following situations:

- If  the function is stretched.

- - If  the function is compressed.

You have that 0<1/4<1

Therefore, you can conclude that be compressed vertically.

Step-by-step explanation:

The given function is f (x) = x²

The new function is f 1 (x) = 1/4 x².

The general function of the form is f(x) = a · x²

i) If |a| < 1   the graph is compressed vertically by a factor of a.

ii)  If |a| > 1  the graph is stretched vertically by a factor of a.

Here:  a = 1/4 < 1

Answer:

A)  False

B)  True

Step-by-step explanation:

For A) First let's do x/11 = 15. If you solved it by now, you will know that the answer is 0.7333333. So now you just do 11x15. Because the answer is different then the answer we got when doing the division, the answer for A is false

For B) B is definitely true because equation are any mathematical sentences that have an equation symbol. So it's like saying 8x3=24 and 6x4=24. These two equations end up with the same answer so B is true.

Answers

Answer:

[tex]71.63 \: \: \mathrm{cm^2 }[/tex]

Step-by-step explanation:

Once we know the diameter of the circle, we can figure out the problem.

The diameter of the circle = The diagonal of the rectangle inscribed in the circle

To find the diagonal of the rectangle, we can use a formula.

[tex]d=\sqrt{w^2 + l^2}[/tex]

The width is 10 cm and the length is 12 cm.

[tex]d=\sqrt{10^2 + 12^2}[/tex]

[tex]d \approx 15.62[/tex]

The diagonal of the rectangle inscribed in the circle is 15.62 cm.

The diameter of the circle is 15.62 cm.

Find the area of the whole circle.

[tex]A=\pi r^2[/tex]

The [tex]r[/tex] is the radius of the circle, to find radius from diameter we can divide the value by 2.

[tex]r = \frac{d}{2}[/tex]

[tex]r=\frac{15.62}{2}[/tex]

[tex]r=7.81[/tex]

Let’s find the area now.

[tex]A=\pi (7.81)^2[/tex]

[tex]A \approx 191.625[/tex]

Find the area of rectangle.

[tex]A=lw[/tex]

Length × Width.

[tex]A = 12 \times 10[/tex]

[tex]A=120[/tex]

Subtract the area of the whole circle with the area of rectangle to find area of shaded part.

[tex]191.625-120[/tex]

[tex]71.625 \approx 71.63[/tex]

Cupcakes (c), come in packs of 6 each, and the brownie bites (b) come in packages of 15. (here is the equation > 6c+15b=75).
Question #1) If the treasurer buys 1 package of brownie bites, how many packages of cupcakes are needed according to this equation? Question #2) If the treasurer buys 7 packages of brownie bites, how many packages of cupcakes are needed according to this equation?

Answers

Answer:

see explanation

Step-by-step explanation:

1) 6c + 15(1) = 75

6c = 60

c = 10 packs of cupcakes

2) 6c + 15(7) = 75

6c + 105 = 75

6c = -30

c = -5, since he bought more brownies than needed, he does not need to buy any cupcakes.

Answer:

6c+15b=75

1)If the treasurer buys 1 package of brownie bites

6(1)+15b=75

15b=75-6

b=69/15=4.6 ( means the treasure needs to buy 5 packages).

2): If the treasurer buys 7 packages of brownie bites,

6c+15(7)=75

6c+105=75

c=-30/6=-5( you can not buy negative amount)

the treasure does not need to buy, because brownies are enough and more.

a. Will this function have a maximum or a​ minimum? How can you​ tell?

b. According to this​ model, in what year will the percent of homes with broadband Internet access be at its maximum or​ minimum?

c. What is the predicted​ maximum/minimum percent of homes with broadband Internet​ access?

Answers

Answer:

a) The function has a maximum at  x = 29,59

b) 99,32 %

Step-by-step explanation:

f(x) = -0,11*x² + 6,51*x + 3

Then:

f´(x) = -0,22*x + 6,51

If   f´(x) = 0   then    - 0,22*x + 6,51 = 0

0,22*x = 6,51

x = 6,51/0,22    ⇒     x = 29,59

if we get the second derivative

f´´(x) = - 0,22       f´´(x) < 0   then we have a maximun at x = 29,59

a) the function has a maximum

b) 29,59 years after 2000   ( in 2030 )

c) f(x) = - 0,11*x² + 6,51*x + 3

f(29,59) = - (0,11)* (29,59)² + 6,51*29,59 + 3

f(29,59) = 99,32 %

Determine how many litres of water will fit inside the following container. Round answer and all calculations to the nearest whole number.

Answers

Answer:

[tex]\approx[/tex] 11 litres of water will fit inside the container.

Step-by-step explanation:

As per the given figure, we have a container formed with combination of a right angled cone placed at the top of a right cylinder.

Given:

Height of cylinder, [tex]h_1[/tex] = 15 cm

Diameter of cylinder/ cone, D = 26 cm

Slant height of cone, l = 20 cm

Here, we need to find the volume of container.[tex]\\Volume_{Container} = Volume_{Cylinder}+Volume_{Cone}\\\Rightarrow Volume_{Container} = \pi r_1^2 h_1+\dfrac{1}{3}\pi r_2^2 h_2[/tex]

Here,

[tex]r_1=r_2 = \dfrac{Diameter}{2} = \dfrac{26}{2} =13\ cm[/tex]

To find the Height of Cylinder, we can use the following formula:

[tex]l^2 = r_2^2+h_2^2\\\Rightarrow h_2^2 = 20^2-13^2\\\Rightarrow h_2^2 = 400-169\\\Rightarrow h_2^2 = 231\\\Rightarrow h_2=15.2\ cm \approx 15\ cm[/tex]

Now, putting the values to find the volume of container:

[tex]Volume_{Container} = \pi \times 13^2 \times 15+\dfrac{1}{3}\pi \times 13^2 \times 15\\\Rightarrow Volume_{Container} = \pi \times 13^2 \times 15+\pi \times 13^2 \times 5\\\Rightarrow Volume_{Container} = \pi \times 13^2 \times 20\\\Rightarrow Volume_{Container} = 10613.2 \approx 10613\ cm^3[/tex]

Converting [tex]cm^{3 }[/tex] to litres:

[tex]10613 cm^3 = 10.613\ litres \approx 11\ litres[/tex]

[tex]\approx[/tex] 11 litres of water will fit inside the container.
