Select the correct answer. Which equation matches the function shown in the graph?​

Mathematics

Kisachek [45]2 years ago

Answer:

B) y=sin(x+\frac{\pi}{2})

Step-by-step explanation:

Technically, since the function starts at its maximum, you could say the function is y=cos(x), but the answer choices all use sine instead. Therefore, we will have to use the cofunction identity cos(x)=sin(x+\frac{\pi}{2}) and we can see that the correct answer is B.

What is 2 and negative three using integers​
Darina [25.2K]

If you mean "how to write the sum", the answer is

2+(-3)

The result of this sum is -1, because you start from 2 on the number line and take 3 steps to the left (negative integers mean going left, positive integers mean going right)

stich3 [128]

Answer:

25m

Step-by-step explanation:

Shannon's rate is 2,500m/100min. Simplifying, we see that this is equal to 25m/1min.

So, she walks 25 m in one minute.

Nina [5.8K]

Deposit $625 into a money market account with a 5% rate for 1 year would result in more money.

<h3>The interest rate of the bank</h3>

To do this, we make use of 1.50% interest rate

<h3>The exponential growth equation</h3>

Here, we have:

Initial, a= 625

Rate, r = 1.5%

The exponential growth equation is

A(t) = a * (1 + r)^t

So, we have:

A(t) = 625 * (1 + 1.5%)^t

Evaluate

A(t) = 625 * 1.015^t

Hence, the exponential growth equation is A(t) = 625 * 1.015^t

<h3>The value in 25 years</h3>

Here, t = 25.

So, we have:

A(25) = 625 * 1.015^25

Evaluate

A(25) = 906.84

Hence, the value in 25 years is $906.84

<h3>The investment with more money</h3>

<u>#Investment A</u>

a = 625

r = 1.5%

t = 5

So, we have:

A(5) = 625 * 1.015^5

Evaluate

A(5) = 673.3

<u>#Investment B</u>

a = 625

r = 5%

t = 1

So, we have:

A(1) = 625 * 1.5^1

Evaluate

A(1) = 937.5

By comparison, 937.5 is greater than 673.3

Hence, deposit $625 into a money market account with a 5% rate for 1 year would result in more money.
