Answer:

[tex]A=160ft^2[/tex]

Step-by-step explanation:

Length of yard [tex]l=37ft[/tex]

Width of yard [tex]w=43ft[/tex]

Walk [tex]l_w=2ft[/tex]

Generally the perameter of the fence P is mathematically given by

[tex]P=l+w[/tex]

[tex]P=37+43[/tex]

[tex]P=80[/tex]

Generally the equation for area of walk is mathematically given by

[tex]A=P*l_w[/tex]

[tex]A=80*2[/tex]

[tex]A=160 ft^2[/tex]

Therefore area of walk is

[tex]A=160ft^2[/tex]

This problem can take a while if you cannot observer the answer quickly.

First of all we can see that 32=2*2*2*2*2=2^5

243, if you don't know its actually is 3^5

Now we can see that this turns into...

- 2^5/3^5

since the 5th power doesn't change the sign of the original number, we can put the negative in the ( ), if you don't know what I mean look below

(-3)^2=9 Positive

(-3)^3=-27 Negative since its to the odd power it keeps the sign.

This problem can be simplified to.

(-2/3)^5

And this is the answer :D

Answer:B

y=13cos(1/13x)+13

Step-by-step explanation:

The cosine equation to model the height of the red spot over a distance you ride is y = 13 cos (x/13) + 13. Then the correct option is B.

It is a function that repeats itself in a particular time interval.

You ride through some wet paint on your bike, creating a red spot on the tire.

Write a cosine equation to model the height of the red spot over the distance you ride.

Your bike tire has a radius (r) of 13 inches.

The period is the circumference of the tire (2πr).

The cosine equation is given as

y = A cos (Bx + C) + D

Where

A = the amplitude

B = time period

C = phase difference

D = shifting of central line

Then we have the diagram

A = 13

B = 1/13

C = 0

D = 13

Then the equation will be

[tex]\rm y = 13 \cos (\dfrac{1}{13}x - 0 ) + 13\\\\y = 13 \cos (\dfrac{x}{13} ) + 13[/tex]

Answer:

Solving steps

We know x= -10-15y, so we can subtract it to the equation above

x = -10-15y

2x+5y=35

2(-10-15y) + 5y = 35

(Refer to the 1st image to solve for y)

Y = -11/5

We now know y= -11/5, so we can subtract it to the equation for x.

Y = -11/5

x = -10-15y

x = -10-15(-11/5)

(Refer to the 2nd and 3rd image to solve for x) (Make sure to look at both images first before writing something down)

x = 33 - 10

x = 23

7.5 * 3 = 22.5 for little rectangle

11.5 * 3 = 34.5 * 2 = 69 for two medioum rectangles

7.5 * 3 = 22.5 for the smallest rectangle

The smallest sample size needed to construct a 99% confidence interval with a margin of error of no more than ±1 inch is 39.

The margin of error (E) for a confidence interval is described as:

E = z × (σ / √n)

where:

E is the desired margin of error

z is the z-score corresponding to the desired confidence level (in this case, 99% confidence level)

σ is the population standard deviation

n is the sample size

In this case, the margin of error is no more than ±1 inch, so E = 1 inch.

Now, determine the z-score corresponding to a 99% confidence level using a standard normal distribution table or statistical software.

For a 99% confidence level, the z-score is approximately 2.576.

Plugging in the known values into the margin of error formula,

1 = 2.576 × (2.4 / √n)

To solve for n, rearrange the formula as follows:

√n = (2.576 × 2.4) / 1

√n = 6.1824

n = (6.1824)²

n ≈ 38.16

Therefore, the smallest sample size needed to construct a 99% confidence interval with a margin of error of no more than ±1 inch is 39.

First, the function was multiplied by 3, which is a vertical dialation by a factor of 3. Then, we subtracted 2 from the function, which is a vertical shift down two units. Therefore, the answer is C

The transformations are applied to the graph of the function should be option c. a vertical dilation by a factor of 3 and a vertical shift down 2 units

Since

First, the function should be multiplied by 3, that represent vertical dilation by a factor of 3. After this, we subtracted 2 from the function, i.e. is a vertical shift down two units.

Answer: m∠E = 55°

Step-by-step explanation: If a triangle has two equal sides, it is called Isosceles. Another characteristics of this type of triangle is that the angles opposite the equal sides are also congruent.

Triangle ΔEFG has two sides with approximately the same length:

[tex]\overline{GE}[/tex] ≈ [tex]\overline{FG}[/tex]

So, it is an isosceles.

Therefore the opposite angles are m∠E and m∠F.

m∠E = m∠F

m∠E = 55°

Angle at vertex E is 55°.

i just had this question

A translation is a transformation that moves every point in a figure in the same direction by the same amount. The coordinates of F' is (-6, 0).

A translation is a transformation that moves every point in a figure in the same direction by the same amount. It is also a sort of transformation in which each point in a figure is moved the same distance in the same direction resulting in the same figure again.

Since the transformation can be defined as the introduction of a new set of mathematical coordinates that are declared to be different functions of the original coordinates.

Given a parallelogram EFGH that is been translated 6 units to the left and 3 units up.

Since the coordinates of F' is (0, -3). Therefore, the coordinates of F’ can be written as,

F = (0, -3)

F' = (0 - 6, -3 + 3)

F' = (-6, 0)

Hence, the coordinates of F' is (-6, 0).
