Answer:

B. 4

Step-by-step explanation:

The given function is of the form:

f(x) = A \cos(x+C).

A is called the amplitude of the given function.

We can read from the graph that, the function ranges between:

-4 and 4

This implies that:

|A| = 4

Therefore the amplitude of the function is 4.

Hence the value of A must be 4.

An equation in point slope form (2,1) and has a slope of m=2
Svet_ta [14]

Answer:

y=2x-3

Step-by-step explanation:

<em>Since we know that the slope-intercept form is </em><em>y=mx+b</em><em>, we can plug in the formula with what we already know to find b!</em>

<em>In the coordinates (2,1): </em>

  • 2 is the x
  • 1 is the y

<em>Now, we will plug these numbers in:</em>

1=2*2+b

1=4+b

b=-3

<em>Now we can rewrite the equation since we found b:</em>

y=2x-3

Hope this helped! :)

Solve the equation <br> 3m=2(4+t) for t
Tanya [424]
3m=2(4+t)
3m= 8+2t
3m-8=2t
(divide everything by 2)
3/2m-4=t

Solve the math problem please
mars1129 [50]

Answer:

B, x≥2

Step-by-step explanation:

54 - 10x ≤ 20 + 7x - subtract 20

34 - 10x ≤ 7x - add 10x to 7x

34 ≤ 17x - divide 34 by 7

2 ≤ x - flip the equation - x ≥ 2

Hope this is helpful!

Solve for x and verify:3(x+3)-2(x-1)=5(x-5)
Gekata [30.6K]

Answer:

x=9

Step-by-step explanation:

Distribute:

3x+9-2x+2=5x-25

Combine like terms:

x+11=5x-25

Solve:

x-x+11=5x-x-25

11=4x-25

11+25=4x-25+25

36=4x

Divide by 9:

x=9.

Hope this helps :D

From the earth, the moon subtends an angle of approximately 0.5°. If the distance to the moon is approximately 240,000 miles, fi
konstantin123 [22]

Answer:

2100 miles.

Step-by-step explanation:

Given:

Diameter to the moon = 240000 miles

∅ = 0.5 °

The subtended angle by an arc is given as:

S = r∅

Where

r = radius of the circle

Therefore,

D = 240,000 x (0.5 x π rads)/180

= 2094 miles

= 2100 miles.
