Evaluate each expression if w=2, x=3, y=5, and z=6. 3+4z

Answer:

Step-by-step explanation:

The expression is 3 + 4z

First, you must know what the value of the variable "z" is.

Because the problem already tells you that z = 6, all you have to do is substitute z with 4:

3 + 4z = 3 + 4(6)

Next, solve using the Order of Operations (P.E.M.D.A.S.).

According to the Order of Operations, multiplication (M) comes before Addition (A). That means you must multiply 4 by 6 first then add the product to 3:

3 + 4(6) = 3 + 24 = 27

"Simple interest" means the interest goes into a separate bucket, and
it just waits there for you to come and get it. It doesn't get added to the
amount in the account, so next year, you don't get interest on the interest.

4 percent of $2000 is (0.04 x 2000) = $80 .

That's how much interest you get each year.

At the end of 4 years, you have (4 x $80) = $320 in the interest bucket.
(And of course, you still have the original $2000 in the account.)

72.2

49.1

31.8

Step-by-step explanation:

In solving this question, remember the annotation SOHCAHTOA

1. We are given the value of the hypotenuse and we are to determine the value of the adjacent side. COS would be used to determine this value

Cos 26 = Adjacent / hypotenuse

cos 26 = x / 15

x / 15 =0.8988

x = 15 x 0.8988 = 13.5

2. We are given the value of the hypotenuse and we are to determine the value of the opposite side. SIN would be used to determine this value

Sin = opposite / hypotenuse

sin 49 = x / 24

0.7547 = x / 24

x = 0.7547 x 24

x = 18.1

3. We are given the value of the opposite side and we are to determine the value of the adjacent side. TAN would be used to determine this value

Tan = opposite / adjacent

tan 14 = 18 /x

18 / 0.2493 = 72.2

4. We are given the value of the adjacent and we are to determine the value of the hypotenuse side. COS would be used to determine this value

cos 67 = opposite / hypotenuse

0.3907 = 5/x

x =5/ 0.3907 = 12.8

to determine the missing angle

7. tan^-1 = opposite / adjacent

8. cos^-1 = adjacent / hypotenuse

9 = sin^-1 = opposite / hyotensue

Use the number 8,6, and 2 and one operation to write an expression that includes an exponent and has a value of 8. Use each numb

podryga [215]

$6 + 2^1 = 8$ is the expression that includes an exponent and has a value of 8

Solution:

Given that, Use the number 8, 6, and 2 and one operation to write an expression that includes an exponent and has a value of 8

We have to use each number only once

Given numbers are 8, 6, 2

Our expression should include exponent and the result should be 8

Among 6 and 2 we can use 2 for exponent

Raise 2 to power of 1

The expression becomes:

$6 + 2^1 = 8$

Here we have used one operation, that is addition

Verifying the expression

$6 + 2^1 = 6 + 2 = 8$

Thus the required expression is found
