18. Water is stored in a cylindrical tank with a diameter of 36 feet. The surface
area of the tank is 4750.1 square feet. What is the height of the tank?

Answer:

[tex]\cos\theta=0.53[/tex]

Step-by-step explanation:

Given that,

[tex]\tan\theta=\dfrac{8}{5}[/tex]

We know that,

[tex]\tan\theta=\dfrac{P}{B}[/tex]

Where

P is perpendicular and B is base

Let H is hypotenuse of triangle. Using Pythagoras theorem,

[tex]H^2=P^2+B^2\\\\H=\sqrt{P^2+B^2} \\\\H=\sqrt{8^2+5^2} \\\\H=9.43[/tex]

We know that,

[tex]\cos\theta=\dfrac{B}{H}\\\\\cos\theta=\dfrac{5}{9.43}\\\\\cos\theta=0.53[/tex]

So, the value of [tex]\cos\theta[/tex] is equal to 0.53.

We have to basically multiply:

11/17 x 475

And simplifying that we get

307.35

And since there can't be .35 person

So out final answer is 307

x = 24.35°

Step-by-step explanation:

Recall that

cos²x - sin²x = cos 2x

which means that

cos 2x = 0.66 ---> 2x = cos^-1 (0.66) = 48.7°

or x = 24.35°

Answer:

x = 24.35, 155.65, 204.35, 335.65  degrees ( for 0 < x < 360 degrees).

Step-by-step explanation:

cos²x - sin²x = 0.66

cos^2 x = 1 - sin^2 x so

1 - sin^2 x - sin^2 x = 0.66

1 - 2sin^2 x = 0.66

2sin^2 x = 1 - 0.66

sin^2x = 0.34/2 = 0.17

sin x = +/- √0.17

= +/- 0.41231

x = 24.35 degrees ( in first quadrant)

and 180 + 24.35 = 204.35 degrees in third quadrant.

Answer:

9 years

Step-by-step explanation:

by using the formula :

20,000(1 + 0.08) ^n = 40,000

=> (1.08)^n = 40,000/20, 000

(1.08) ^n = 2

n = 9

[tex]\\ \rm\Rrightarrow P(1+r)^n=I[/tex]

[tex]\\ \rm\Rrightarrow 20000(1+0.08)^n=40000[/tex]

[tex]\\ \rm\Rrightarrow (1.08)^n=2[/tex]

[tex]\\ \rm\Rrightarrow log(1.08)^n=log2[/tex]

[tex]\\ \rm\Rrightarrow nlog1.08=log2[/tex]

[tex]\\ \rm\Rrightarrow n(0.033)=0.3[/tex]

[tex]\\ \rm\Rrightarrow n=3(3)=9[/tex]

Answer:

36 meters^3

Step-by-step explanation:

Formula: Bh

B=Base area

h=height

to find the base area, multiply 2 and 6

2x6 = 12

B=12

and the height is given, so just insert your numbers into the formula

12x3=36

Answer:

Area = 21 un²

Explanation down Below!

Step-by-step explanation:

You don't need to worry about the 8 at all at this point

To find the area of a parallelogram you need to do base x height.

The height is 7, and the base of that height is 3.

7 x 3 = 21

Let me tell you why you do base x height.

if you cut out the triangle from the top and place it at the bottom it will become a rectangle.

The formula for a rectangle is base x height so this is why the formula works.

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

Explanation:

Graph B, C and D all fail the vertical line test. If it's possible to pass a vertical line through more than one point on the curve, then it's said to have failed the vertical line test. Any vertical line itself therefore is automatically not a function. If a graph fails the vertical line test, then it is not a function.

A function is only possible if for any given input x, we have exactly one and only one output. For graph A, the output is the same value regardless of the input. This is a constant function.

For something like graph B, the input x = 0 produces three different y outputs. The output y = 0 is one of those, and the others are off the screen so it's hard to tell what they are. Turns out it doesn't matter and all we need to do is the vertical line test. Graphs C and D are a similar story. In the case of graph D, the only input x allowed is x = 2 and it produces infinitely many y outputs.

On your calculator go to stat-edit and enter the table. Press stat and go over to calc then press 4 and hit calculate it will give you the answer.

The slope of the line that is these data is 0.03 or 3/100

The correct option is (B).

The slope of a line is a measure of its steepness.

Given that:

Time              Distance

50                       1.5

200                      6

350                    10.5

400                      12

650                    19.5

Let us take,

[tex]x_1[/tex]=1.5, [tex]x_2[/tex]= 6, [tex]y_1[/tex]= 50, [tex]y_2[/tex]= 200

Slope of line, m= Δy/Δx

                       m=  [tex]x_2[/tex]- [tex]x_1[/tex]/ [tex]y_2[/tex]-  [tex]y_1[/tex]

                       m=6-1.5 /200-50

                       m=4.5 /150

                       m= 45/1500= 3/100

                      m=0.03

Hence, slope of line is= 0.03

ok so you have to take out c beacsue ########

Answer:

<A = 56degrees

<B = 34degrees

<C = 56degrees

Step-by-step explanation:

From tyhe diagram, the sum of m<C and m<D is 180degrees. Hence;

<C + <D = 180

<C + 124 = 180

<C = 180 - 124

<C = 56degrees

Also;

<B + 90 + <C = 180

<B + 90 + 56 = 180

<B  + 146 = 180

<B = 180 - 146

<B = 34degrees

Similarly;

<A + <B = 90

<A + 34 = 90

<A = 90 - 34

<A = 56degrees
