Answer:

amplitude = 2

Step-by-step explanation:

Given

y = a cosbx

amplitude = | a | , period = [tex]\frac{2\pi }{b}[/tex]

y = 2cos2∅

with amplitude = | 2 | = 2

Answer:

[tex]\displaystyle 2[/tex]

Step-by-step explanation:

[tex]\displaystyle y = Acos(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A|[/tex]

With the above information, you should now tell what the amplitude value is.

I am joyous to assist you at any time.

Answer:

A) 1, 4, 5, 9, 14, 23, 37

B) 2, 4, 6, 10, 16, 26, 42

Step-by-step explanation:

1. The Fibonacci sequence states that each number is the sum of the two numbers before it.

2. Given the information above, let's solve the question.

-> A: 9 + 14 = 23, 14 + 23 = 37

-> B: 10 + 16 = 26, 16 + 26 = 42

Therefore, the answer is:

A) 1, 4, 5, 9, 14, 23, 37

B) 2, 4, 6, 10, 16, 26, 42

Answer:

x=33

Step-by-step explanation:

(x+20)+(4x-5)=180

5x+15=180

5x=165

x=33

Answer:

<1 = 82.9 degrees

<2 = 7.1 degrees

Step-by-step explanation:

<1 = x

<2 = x - 75.8

x + x - 75.8 = 90 degrees

2x = 90 + 75.8

x = 165.8/2

x = 82.9

Answer:

15 minutes

Step-by-step explanation:

I added just to get 15 because 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 Wich will be 10:00

Step-by-step explanation:

one gallon is 128oz.

1445 gallons are how many Oz?

that applies the same principle as every-day situations like "every guest will eat 2 dumplings. 12 guests are coming, so how many dumplings do I have to prepare ?"

or totally simple : "every child will get one gift. 4 children are coming, so how many gift do I have to prepare ?"

it all works with multiplication. it is the ultimate application for multiplication.

that is why we use "times" in normal language as in mathematical terms. like "it takes 3 screws to mount a leg to a table. and the table needs 4 legs. how many times do I need to fasten a screw to finish one table ?" well, 4 times 3 or 4×3 = 12 times.

and so, the answer to the original question is then I need to take the amount of one gallon 1445 times.

128 × 1445 = 184,960oz

Answer:

30°

Step-by-step explanation:

as sum of angles = 180°

so 180° -(90° + 60°) = 30°

[tex]\qquad[/tex] ☀️It's given,One angle of a right triangle measures 60°.

[tex]\qquad[/tex] According to the question :-

[tex]\qquad \longrightarrow {\purple {\underline{\underline{\pmb{\sf{ Sum_{(All \:angles) }= 180°}}}}}}[/tex]

[tex]\qquad \pmb{\sf\longrightarrow 60° + 90° + x = 180°}[/tex]

[tex]\qquad \pmb{\sf\longrightarrow 150° + x = 180°}[/tex]

[tex]\qquad \pmb{\sf\longrightarrow x = 180° - 150°}[/tex]

[tex]\qquad \longrightarrow {\pink{\underline{\underline{\pmb{\sf{ x= 30°}}}}}}[/tex]

Answer:

D

Step-by-step explanation:

[tex]Tan \ 19 = \dfrac{Opposite \ side}{Adjacent \ side}\\\\0.3443 = \dfrac{x}{15}\\\\0.3443*15=x[/tex]

x = 5.1645

x = 5.2

Answer:

Step-by-step explanation:

The usual definition of pi is the ratio of the circumference of a circle to its diameter, so that the circumference of a circle is pi times the diameter, or 2 pi times the radius. The animation above shows that a circle can be cut and rearranged to closely resemble a parallelogram (with height r and base pi times r) of area pi times the square of the radius. By dividing the circle into more than eight slices, the approximation obtained in this manner would be even better. By dividing the circle into more and more slices, the approximating parallelograms approximate the area of the circle arbitrarily close. This give a geometric justification that the area of a circle really is "pi r squared".

Answer:

Your financial situation.

Step-by-step explanation:

x / 2 - 1 = 3

Add 1 to both sides.

x / 2 = 4

Multiply both sides by 2.

x = 8

Now lets put in 8 for x in our original equation:

8 / 2 - 1 = 3

4 - 1 = 3

3 = 3

This is correct, therefore we know x = 8.

I hope I've helped! :)

Step-by-step explanation:

The Inaquality Notation should be ( x < - 3 ), you have it right but need to turn the arrow around or you can put in another form. ( x > 0 ) with line under the arrow.

Answer:

66 mph

Step-by-step explanation:

w = e - 18

2w + 2e = 300

2 (e - 18) + 2e = 300

2e - 36 + 2e = 300

4e - 36 = 300

4e = 300 + 36 = 336

e = 84 mph

w = 66 mph

The westbound train is travelling at 66 mph

Yes, with some change to spare.

Step-by-step explanation:

He has 20$. Take 1/5 of it, it's 4$ (because 4x5 = 20), so he will be left with 16$. He owes less than this, 15$, so he can repay his debt in full and have still 1$ left.

Answer:

123

Step-by-step explanation:

First of all, you have to find the total amount of people surveyed, so you add 82+105+141, which would be 328. Then you have to find 37.5% of 328, which is 123 only childs that have no pets.

Answer:

Step-by-step explanation:

Looks like a  typo in the question

To get the unit rate, divide the miles by the hours

Unit rates

1000 miles in 2 hours = 1000/2 = 500

I'm guessing you meant 100 miles not 1000 miles

100 miles in 2 hours = 100/2 = 50
