Answer:

<u>a₂₀ = 60</u>

Step-by-step explanation:

<u>Given :-</u>

a₃ = 9

a₈ = 24

<u>To find :-</u>

a₂₀

<u>Solving :-</u>

Expand the given values.

a + 2d = 9 -(1)

a + 7d = 24 -(2)

Now subtract (1) from (2).

=> 5d = 15

=> d = 3

a = 9 - 2d

a = 9 - 6

a = 3

<u>Final answer :-</u>

a₂₀

= a + 19d

= 3 + 19(3)

= 3+ 57

= 60

<u>a₂₀ = 60</u>

The answer is 180 degrees. 

A right angle formed at the edge of any circle will always create an arc of 180 degrees. This is true no matter where it is placed and no matter the side lengths.

\frac{35}{4} feet below the surface

adding the 2 quantities

3 \frac{1}{2} + 5 \frac{1}{4}

= (3 + 5 ) + (\frac{1}{2} + \frac{1}{4})

= 8 + (\frac{2}{4} + \frac{1}{4})

= 8 + \frac{3}{4} = 8 \frac{3}{4} = \frac{35}{4}

PLEASE HELP FAST!
ollegr [7]

Given two functions are

f(x) = 2 cos(x)

g(x) = 3 sin(x+ \pi)

We know that the maximum value of cos x and sin x is always 1

y= maximum of cos = 1

y= maximum of sin =1

f(x) = 2 cos(x)

y= 2 (max of cos) = 2(1) = 2

g(x) = 3 sin(x+ \pi)

y= 3 (max of sin) = 3(1) = 3

g(x) = 3 sin(x+ \pi) has the maximum value.

Identify the sine function with the given attributes.
Thepotemich [5.8K]

Answer:

<em>Last option </em>

f(t)=sin(\pi(t -3)) + 4

Step-by-step explanation:

The general sine function has the following form  

y = Asin(bt-\phi) + k

Where A is the amplitude: half the vertical distance between the highest peak and the lowest peak of the wave.  

\frac{2\pi}{b} is the period: time it takes the wave to complete a cycle.

k is the vertical displacement.

\phi phase shift

We know that:

amplitude: 1; period: 2; phase shift: 3; vertical shift: 4

Thus:

A =1

\frac{2\pi}{b}=2

b=\pi

\phi=3

k=4

Then the function is:

f(t)=sin(\pi(t -3)) + 4

The answer is last option
