Do 15^2 +10^2=c^2 than put answer Into \sqrt()

Step-by-step explanation:

Ok, so the pythagorean theorem is a^2 + b^2 = c^

where c is the hypotenuse and b and a are the the other 2 sides

9) 10^2 + b^2 = 15^2

100 + b = 225

-100 -100

b^2 = 125

sqrt of 125 = 5

b = 5

10) 2^2 + 5^2 = C^2

4 + 25 = c^2

sqrt of 29 = c

c = [tex]\sqrt{29\\}[/tex]

11) 42^2 + a^2 = 48^2

1764 + a^2 =2304

Answer:

Step-by-step explanation:

Used graphing calculator. Correct on edge.

By transformations, the resultant graph will be option D.

What is called Dilation?Dilation is a non-rigid transformation that stretch the graph vertically.If F(x) = k.f(x), then the graph will stretch vertically by k units.

What is translation?Translation is a rigid transformation that shift the graph upwards or downwards.If F(x)=f(x)+k, then the graph shift upwards k units.If F(x)=f(x)-k, then the graph shift downwards k units.

A company that makes robotic vacuums claims that their newest model of vacuum lasts, on average, two hours when starting on a full charge. To investigate this claim, a consumer group purchases a random sample of five vacuums of this model. They charge each unit fully and then measure the amount of time each unit runs. Here are the data (in hours): 2.2, 1.85, 2.15, 1.95, and 1.90. They would like to know if the data provide convincing evidence that the true mean run time differs from two hours. The consumer group plans to test the hypotheses H0: μ = 2 versus Ha: μ ≠ 2, where μ = the true mean run time for all vacuums of this model. Are the conditions for inference met?

No, the random condition is not met.
No, the 10% condition is not met.
No, the Normal/large sample condition is not met.
Yes, all conditions for inference are met.

The shape of the histogram can be approximated with a normal curve.
The histogram will show that most of the data is centered between 6 minutes and 9 minutes.

Answers

Answer:

A, D, E

Step-by-step explanation:

GOT IT RIGHT ON EDGE

The true statement about the histogram are

(a) the median and the mean are approximately equal(d) the histogram would have an approximately normal curve(e) there are more data elements between 6 and 9.

How to interpret the histogram?

The dataset is given as:

5.5, 6, 7, 10, 7.5, 8, 9.5, 9, 8.5, 8, 7, 7.5, 6, 6.5, 5.5

Using a statistical calculator, we have the following summary:

Mean = 7.43

Median = 7.5

Notice that the median and the mean are approximately equal

i.e. 7.43 ≈ 7.5

When the mean and the median are equal, the histogram would have an approximately normal curve

Also, when the dataset is sorted, we have:

5.5, 5.5, 6, 6, 6.5, 7, 7, 7.5, 7.5, 8, 8, 8.5, 9, 9.5, 10

Notice that there are more data elements between 6 and 9.

Hence, the true statement about the histogram are (a), (d) and (e)

The general equation of the sinusoid is [tex]f(x)=sinx[/tex]

What is sinusoidal?

"A sine wave or sinusoidal is a continuous or mathematical curve which is used to describe a smooth periodic oscillation."

We know,

A Sinusoidal function is a function that can be modelled using a sine wave.

The sine graph repeats itself after a period of 2π, which shows the function is periodic with a period of 2π.

f (x) = sin x and f (x) = cos x are similar apart from a phase shift, both functions are sinusoidal.

f (x) = tan x is a trigonometric function, but its graph is completely different.

The graph of a sinusoidal function is a smooth periodic graph.

The graph is continuous all over the x-axis and also it repeats itself after every fixed interval.

∵ A phase shift is the only difference between sine and cosine, any sinusoidal function that can be modelled using sine can also be modelled using cosine.

The general sinusoidal function is [tex]f(x)=[/tex]±[tex]a.sin(b(x+c))+d[/tex]

Where as,

± controls the reflection across the x - axis, coefficient a controls the amplitude , constant d controls the vertical shift, coefficient b controls the horizontal stretch.

∴ The general equation of the sinusoid is [tex]f(x)=sin x[/tex]

The volume of a cylinder is 14,130 ft 3 . If the diameter is 30 feet, calculate the height of the cylinder

Answers

Answer:

V = PI*r2h

In plain english the volume of a cylinder can be calculated by squaring the radius, multiplying that value by PI, then multiplying by the height. You can also think of it as finding the area of a flat circle (PI * radius squared) and multiplying by the height to find volume.

Here is a step-by-step case that illustrates how to find the volume of a cylinder with a radius of 3 inches and a height of 5 inches. In this example PI will be 3.14.

V = pi * r2 * h

= pi * 32 * 5

= pi * 9 * 5

= 3.14 * 45

= 141.37 cubic inches

Step-by-step explanation:

The formula for the volume of a cylinder is V=Bh or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm.

The height of the cylinder is given by h = 20 feet

What is a Cylinder?

A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface. The center of the circular bases overlaps each other to form a right cylinder. The volume of a cylinder is

Volume of Cylinder = πr²h

Surface area of cylinder = 2πr ( r + h )

where r is the radius of the cylinder

h is the height of the cylinder

Given data ,

Let the height of the cylinder be h

Now , the volume of the cylinder V = 14,130 feet³

The diameter of the cylinder d = 30 feet

So , the radius of the cylinder r = d/2 = 15 feet

And , Volume of Cylinder = πr²h

On simplifying , we get

14,130 = π( 15 )²h

Divide by 225 on both sides , we get

πh = 62.8

Divide by π on both sides , we get

h = 62.8 / 3.14

h = 20 feet

Therefore , the value of h is 20 feet

Hence , the height of the cylinder is 20 feet
