Answer:

C

Step-by-step explanation:

First find the voltage which is current times resistance. Convert milliamperes to amperes. Divide 250/1000 because amperes are 1000 times smaller. That results in 0.25. So multiply 0.25 A by 5 ohms. That is 1.25. Now divide 20 by 1.25 which is 0.0625. Convert that to millamperes by multiplying by 1000. That gives you 62.5 millamperes.

Please write y = x^2.  The " ^ " symbol indicates exponentiation.

Here's how we get from the graph of y = x^2 to the graph of y = x^2 + 8:

Graph y = x^2.  Now translate the entire graph 8 units up.

Answer:

16/81

Step-by-step explanation:

Given the expression, 81y'' = -16y where y = coskt,

We want to know the value of k that satisfies the expression

y' = -ksinkt

y" = -k²coskt

Substitute y and y" into the expression given;

81y'' = -16y

81(-k²coskt) = -16(kcoskt)

-81k = -16

Divide both sides by -81

-81k/-81 = -16/-81

k = 16/81

Hence the value of k is 16/81

Answer:

Their product is 42

Step-by-step explanation:

Let the numbers be A and B

Such that:

[tex]A + B = 13[/tex]

[tex]A - B = 1[/tex]

Required

Determine A * B

Add both equations together:

[tex]A + A + B - B = 13 + 1[/tex]

[tex]2A = 14[/tex]

Solve for A

[tex]A = 7[/tex]

Substitute 7 for A in the second equation

[tex]7 - B = 1[/tex]

Make B the subject

[tex]B = 7 - 1[/tex]

[tex]B = 6[/tex]

Hence,

A = 7 and B = 6

So:

[tex]A * B = 7 * 6[/tex]

[tex]A * B = 42[/tex]

The product of the two numbers will be 42.

Let the two numbers be A and B

A + B = 13

A - B = 1

A = 1 + B.

Therefore, since A + B = 13, then (1 + B) + B = 13

1 + 2B = 13

2B = 13 - 1

2B = 12

B = 6

A = 6 + 1 = 7

Since the numbers are 6 and 7, then multiplying them is 42.

Answer:

a = (u-b)/k

Step-by-step explanation:

to solve for a means to leave a on its own

u = b + ak

let’s subtract b from both sides to leave a on its own

u - b = ak

to leave a on its own we’ll divide both sides by k

a = (u-b)/k

ummm.. i think its 7.8?

The value of the division of the number 39 by 5 is 7.8.

A mathematical procedure called division involves dividing a quantity or number into equal pieces or groups. It is used to calculate how many times one number (the divisor) may be subtracted from another (the dividend) in order to get an accurate answer or a quotient. It is the opposite operation of multiplication.

To estimate 39 divided by 5, we can use rounding to simplify the calculation.

Round 39 to the nearest multiple of 5. In this case, 39 is already a multiple of 5, so we don't need to round it.

Divide the rounded number by 5. Since 39 is already a multiple of 5, we can directly divide it by 5.

39 ÷ 5 = 7.8

So, an estimated value for 39 divided by 5 is 7.8.
