What Is The Value Of The Expression?

Answers

Answer 1

Answer:

-3

Explanation:

4 + 3 = 7

7² = 49

2 · 5 = 10

49 ÷ 7 = 7

7 - 10 = -3

Answer 2

Answer:

-3

Step-by-step explanation:

Hi!

You would get -3.

You would use Pemdas to simplify the equation.

Pemdas is parenthesis exponents multiplication division additin and subtraction in the order to do them.

First, you would do the math in the parenthesis, which equals 7.

Then, you would use the exponent which would be 7 x 7 which is 49.

Next, you would use multiplication which is 2 times 5 which is 10.

Next, you would divide, which is 49 divided by 7 which equals 7.

Now, you go from left to right which would give you -3.

Hope this helps!

how would you differentiate this problem using the quotient rule?

Answers

rewrite the square root of X as X^ 1/2. Then take the derivative. Since 1/3 is a constant with respect to X you can pull that out. So, you should have
1/3 d/dx [ (2x^2-x^5)/3x^1/2].

Then factor x^2 out of 2x^2-x^5.

Then by using the negative exponent rule you should have

1/3 d/dx [ x^2(2-x^3)x^-1/2 ]

Then multiply x^2 by x ^-1/2 by adding the exponents.

1/3 d/dx [ x^3/2 (2-x^3)]

Then differentiate.

You should get x^1/2 - (3x^7/2)/2.

I hope that helps.

Answer:

C. 24 degrees

Step-by-step explanation:

All triangle must be 180 degrees in total. So you have to add all the known degrees together to find the missing degree.

120+36=156

Then subtract the sum of the known angles from 180 to find the degree of the unknown angle

180-156=24

Answer: C

Step-by-step explanation:

I'll explain why.

The sum of the angles in a triangle must be equal to 180º. We already know 2 of the 3 angles, therefore, we can make an equation to find x.

The sum of the angles (x+36+120) must be equal to 180 (=180)

x+36+120=180

Combine like terms

x+156=180

Subtract 156 to isolate x

x=180-156

x=24

What is the range of f(x)=(3/4)x-4

Answers

Answer:

Range of the function f(x) is all real numbers greater that -4, i.e., (-4,∞).

Step-by-step explanation:

The given function is f(x) = (3/4)x - 4

The value of (3/4)^x is greater than zero for any value of x. (3/4)^x > 0

Subtract 4 from both the sides. (3/4)^x - 4 > 0 - 4

f(x) > -4

The value of f(x) is greater than -4 for any value of x.

Therefore, the range of the function f(x) is all real numbers greater that -4. (-4,∞).

A.) 2

B.) 7

C.) 13

D.) 22

Answers

Answer:

B.) 7

Step-by-step explanation:

7 x 4 = 28

28 + 12 = 40

:)

Using multiplication, the original number is 7.

What is multiplication?

Multiplication is "the process multiplying that the integer is multiplied by number of time".

According to the question,

A number is multiplied by 4. The results is added to 12. The final number is 40. In order to find original number.

4x + 12 = 40

        4x = 40 -12

        4x = 28

          x = 28/4

          x = 7.  

Hence, using multiplication, the original number is 7.

2x + y =6
y = x-3


Solve for x and y

Answers

Answer:

x = 3, y=0

Step-by-step explanation:

2x + y =6

y = x-3

Substitute the second equation into the first

2x +x-3 =6

Combine like terms

3x-3 =6

Add 3 to each side

3x-3+3 = 6+3

3x= 9

Divide each side by 3

3x/3 = 9/3

x =3

Now we need to find y

y = x-3

y = 3-3=0

y=0

125,600 surface area converted to volume?

Answer:

Step-by-step explanation:

My example:

Find the radius of the sphere by substituting 4.5? ft^3 for V in the formula in Step 1 to get: V=4.5? cubic feet.= (4/3)?(r^3)

Multiply each side of the equation by 3 and the equation becomes: 13.5 ? cubic feet =4?(r^3)

Divide both sides of the equation by 4? in Step 4 to solve for the radius of the sphere. To get: (13.5? cubic feet)/(4?) =(4? )(r^3)/ (4?), which then becomes: 3.38 cubic feet= (r^3)

Use the calculator to find the cubic root of 3.38 and subsequently the value of the radius “r” in feet. Find the function key designated for cubic roots, press this key and then enter the value 3.38. You find that the radius is 1.50 ft. You can also use an online calculator for this calculation (see the Resources).

Substitute 1.50 ft. in the formula for SA= 4?(r^2) found in Step 1. To find: SA = 4?(1.50^2) = 4?(1.50X1.50) is equal to 9? square ft.

Substituting the value for pi= ?= 3.14 in the answer 9? square ft., you find that the surface area is 28.26 square ft. To solve these types of problems, you need to know the formulas for both surface area and volume.
