Answer:

x = 73.3

y = 46.2

Step-by-step explanation:

Reference angle (θ) = 39°

Adjacent = 57

Hypotenuse = x

Opposite = y

Recall: SOHCAHTOA

✔️To find x, apply CAH:

Cos θ = Adjacent/Hypotenuse

Plug in the values

Cos 39° = 57/x

x × Cos 39° = 57

x = 57/Cos 39°

x = 73.3 (nearest tenth)

✔️To find x, apply TOA:

Tan θ = Opposite/Adjacent

Plug in the values

Tan 39° = y/57

57 × Tan 39° = y

y = 46.2 (nearest tenth)

Step-by-step explanation:

The volume of a square pyramid is given in terms of perimeter and height by ...

  V = (1/48)P²h

  V = (1/48)(10.4 in)²(9.6 in) ≈ 21.6 in³

The volume is about 21.6 cubic inches.

Answer:

4th term = 0

6th term = -4

13th term = -18

Step-by-step explanation:

a(n) = 6 + -2(n-1)

a(4) = 6 + (-2)(3) which is 6-6

a(6) = 6 + (-2)(5) which is 6-10

a(13) = 6 + (-2)(12) which is 6-24

Answer:

8ft. 9in.

+13ft. 7in.

_________

22ft. 4in.

because 12 in.= 1 ft. so 9+7=16

16-12=4

so 12in.=1 ft. , as 12 in, got carried by 1ft.

Answer:

8.8

Step-by-step explanation:

To find the hypotenuse...

a²+b²=c²

C is the hypotenuse, so we add the others...

8.4²+2.6²=c²

70.56+6.76=c

77.32=c

Now, square root c to bring it to its original position.

√77.32=8.8

The vertex is (-5, 4). The parabola opens downward, so the vertex is a maximum. The range of the function is (-∞, 4]. The vertical scale factor is -4, so the graph will appear narrower than that of the parent function.

Answer:

Step-by-step explanation:

==========================================================

Explanation:

Add up the percentage values:

25+20+6+6+6 = 63

This means 63% of the trip was driven by anyone but Dan. That must mean 100-63 = 37% of the trip is how much Dan drove.

Apply this percentage to the 20 hour duration

37% of 20 = 0.37*20 = 7.4 hours represents how long Dan drove.

C, definitely two sides are different in the triangle.

A, it looks as if the bottom is a right triangle if you look at it in a different way.

The polygons that would be used in a net isosceles triangle & right triangle

A pyramid is a structure whose outer surfaces are triangular and converge to a single step at the top,

As, we need a triangular pyramid whose base has all the three sides equal in length.

We can have a net in the form of isosceles triangle whose two are equal

i.e., two sides are different in the triangle.

and also, bottom with the right angle

i.e.,  the bottom is a right triangle if you look at it in a different way.

Answer:

[tex]t = 31.29[/tex]

Step-by-step explanation:

Given

[tex]\begin{array}{ccccccc}{Stick} & {25.8} & {26.9} & {26.2} & {25.3} & {26.7}& {26.1} \ \\ {Liquid} & {16.9} & {17.4} & {16.8} & {16.2} & {17.3}& {16.8} \ \end{array}[/tex]

Required

Determine the test statistic

Let the dataset of stick be A and Liquid be B.

We start by calculating the mean of each dataset;

[tex]\bar x =\frac{\sum x}{n}[/tex]

n, in both datasets in 6

For A

[tex]\bar x_A =\frac{25.8+26.9+26.2+25.3+26.7+26.1}{6}[/tex]

[tex]\bar x_A =\frac{157}{6}[/tex]

[tex]\bar x_A =26.17[/tex]

For B

[tex]\bar x_B =\frac{16.9+17.4+16.8+16.2+17.3+16.8}{6}[/tex]

[tex]\bar x_B =\frac{101.4}{6}[/tex]

[tex]\bar x_B =16.9[/tex]

Next, calculate the sample standard deviation

This is calculated using:

[tex]s = \sqrt{\frac{\sum(x - \bar x)^2}{n-1}}[/tex]

For A

[tex]s_A = \sqrt{\frac{\sum(x - \bar x_A)^2}{n-1}}[/tex]

[tex]s_A = \sqrt{\frac{(25.8-26.17)^2+(26.9-26.17)^2+(26.2-26.17)^2+(25.3-26.17)^2+(26.7-26.17)^2+(26.1-26.17)^2}{6-1}}[/tex]

[tex]s_A = \sqrt{\frac{1.7134}{5}}[/tex]

[tex]s_A = \sqrt{0.34268}[/tex]

[tex]s_A = 0.5854[/tex]  

For B

[tex]s_B = \sqrt{\frac{\sum(x - \bar x_B)^2}{n-1}}[/tex]

[tex]s_B = \sqrt{\frac{(16.9 - 16.9)^2+(17.4- 16.9)^2+(16.8- 16.9)^2+(16.2- 16.9)^2+(17.3- 16.9)^2+(16.8- 16.9)^2}{6-1}}[/tex]

[tex]s_B = \sqrt{\frac{0.92}{5}}[/tex]

[tex]s_B = \sqrt{0.184}[/tex]

[tex]s_B = 0.4290[/tex]

Calculate the pooled variance

[tex]S_p^2 = \frac{(n_A - 1)*s_A^2 + (n_B - 1)*s_B^2}{(n_A+n_B-2)}[/tex]

[tex]S_p^2 = \frac{(6 - 1)*0.5854^2 + (6 - 1)*0.4290^2}{(6+6-2)}[/tex]

[tex]S_p^2 = \frac{2.6336708}{10}[/tex]

[tex]S_p^2 = 0.2634[/tex]

Lastly, calculate the test statistic using:

[tex]t = \frac{(\bar x_A - \bar x_B) - (\mu_A - \mu_B)}{\sqrt{S_p^2/n_A +S_p^2/n_B}}[/tex]

We set

[tex]\mu_A = \mu_B[/tex]

So, we have:

[tex]t = \frac{(\bar x_A - \bar x_B) - (\mu_A - \mu_A)}{\sqrt{S_p^2/n_A +S_p^2/n_B}}[/tex]

[tex]t = \frac{(\bar x_A - \bar x_B) }{\sqrt{S_p^2/n_A +S_p^2/n_B}}[/tex]

The equation becomes

[tex]t = \frac{(26.17 - 16.9) }{\sqrt{0.2634/6 +0.2634/6}}[/tex]

[tex]t = \frac{9.27}{\sqrt{0.0878}}[/tex]

[tex]t = \frac{9.27}{0.2963}[/tex]

[tex]t = 31.29[/tex]

The test statistic is 31.29

Answer:A. 8.5 ft

Step-by-step explanation:

edge2021

The width of the footpath is 8.5 feet.

Radius of a circle is the distance from the center of the circle to any point on it's circumference.

given equation is :x² + y² = (r)²

We have for the pool:

x²  +  y²  = 2500      or   x²  +  y²  = (50)²

So, for the outside edge of the footpath

x²  +  y²  = 3422.25  or x² + y²  = (58.5)²

So, we find the radius of each circumference

r₁  = 50 feet

r₂ = 58,5  feet

58,5  - 50  =  8,5 feet

Thus, width of the footpath is 8.5 feet.
