The period of a periodic function is 8 s . How many cycles does it go through in 30 s ?

1 answer:

7 0

The number of cycles of the periodic function is 3.75 cycles if the period of a periodic function is 8 s option (G) 3.75 is correct.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

The period of a periodic function is 8 s

From the question:

8n = 30

n = 30/8

n = 3.75 cycles

Thus, the number of cycles of the periodic function is 3.75 cycles if the period of a periodic function is 8 s option (G) 3.75 is correct.

B. Find the value of X. Show your work, I’m not sure how to do this

Eddi Din [679]

Answer:

63°

Step-by-step explanation:

The sum of all interior angles of a triangle = 180°

Therefore:

x + 96° + 21° = 180°

x + 117 = 180

Subtract 117 from each side

x = 180 - 117

x = 63°

Does the system have no solution?

kvv77 [185]

Answer:

$\mathrm{A)\:}-6$

Step-by-step explanation:

Notice that in the second equation, the coefficient of $y$ is $2$ times greater than in the first. Therefore, by making the coefficient of $x$ in the second equation $2$ times greater than in the first, it's impossible to only isolate one variable.

Therefore, when $a=-3\cdot 2=\fbox{-6}$ , there are no solutions to this system.

What is the quotient of d − 2 √ d 4 − 5 d 3 + d + 17

Tcecarenko [31]

Answer: $d^3 - 3d^2-5$

Step-by-step explanation:

For finding the quotient of the given division,

In the long division method, we will follow the following steps.

Step 1 : Here the divisor is d-2 and dividend is $d^4-5 d^3 + d + 17$

Multiply (d-2) by $d^3$ and subtract the dividend by the resultant.

We get $-3d^3+d$

Step 2: Multiply (d-2) by $-3d^2$ and subtract the remaining dividend by the resultant.

We get $-5d^2+17$

Step 3 : Multiply (d-2) by $-5$ and subtract the remaining dividend by the resultant.

We get $7$

Since, after getting 7 it is not possible further division,

Hence, Remainder = 7,

Quotient = sum of all expression by that we multiply (d-2) = $d^3 - 3d^2-5$
