Answer:

D. 2^7

Step-by-step explanation:

Answer:

2^7

Step-by-step explanation:

When we multiply the same bases with exponents like 2^3*2^4 we can add the exponents and keep the base the same

2^7 would be the answer or you can simplify further to get 128

but they said simplify so 2^7 is the answer

If they said evaluate then our answer is 128

Answer:

(0, -5/2), (-2, 0)

Step-by-step explanation:

To find the y-intercept, set x = to 0 and find y:  -4y = 10.  Thus, y = -5/2.  The y-intercept is (0, -5/2).

To find the x-intercept, set y = to 0 and fid x:   -5x = 10.    Therefore the x-intercept is -2:  (-2, 0)

Answer:

7 + 11i

Step-by-step explanation:

Simplify: (2 +8i)-(-5 - 3i) = 2 + 8i + 5 + 3i  

Add real numbers to real numbers and imaginary to imaginary: 2 + 8i + 5 + 3i = 7 + 11i

A complex number can be shown as a pair of integers (a, b). The difference of the complex number (2 +8i)-(-5 - 3i) is 7+11i.

A complex number can be shown as a pair of integers (a, b) forming a vector on an Argand diagram, which represents the complex plane.

The difference of the complex number can be done as following,

(2+8i)-(-5-3i)

= 2 + 8i + 5 + 3i

= 5+2 + 8i+3i

= 7 + 11i

Hence, the difference of the complex number (2 +8i)-(-5 - 3i) is 7+11i.

Answer:

Future Value= $207,234.2

Step-by-step explanation:

Giving the following formula:

Initial value (PV)= $140,000

Appreciation rate (r)= 4% = 0.04

Number of years (n)= 10

To calculate the future value of the car after ten years, we need to use the following formula:

FV= PV*(1+i)^n

FV= 140,000*(1.04^10)

FV= $207,234.2

Answer:

Equation B and Equation C

Step-by-step explanation:

We can pinpoint a solution of an equation on a graph by looking at where the two lines intersect. The points (2,12) quite literally mean when x is 2, y is 12. If two equations intersect at that very point, that is their solution.

Answer:

12.5 if all the numbers are one set. 15.3 for first row and 10 for last row if they are separate

Step-by-step explanation:

mean is found by adding all the data from the set and then dividing by how many data's there are. Mean can also be called the average of a set of data.

r = √153.9/pi

r = √49.01

r = 7

Answer:

10.5m

Step-by-step explanation:

We solve the above question, using the Trigonometric function of Tangent

tan θ = Opposite/Adjacent

θ = 52.7 °

Adjacent = 8 m

Opposite = x

Hence,

tan 52.7= x/8m

Cross Multiply

x = tan 52.7 × 8m

x = 10.501501092m

Approximately = 10.5 m

Therefore, the height of the pole = 10.5m

Answer:

$11.33

Step-by-step explanation:

First I did 8.80 x 0.25 and I got 11. Than I did 11.00 x 0.03 and I got $11.33. The total cost was $11.33

The total cost of the rake is $11.33.

Calculating the sales tax applied to a purchase is a matter of simply multiplying the tax rate by the purchase price using the equation sales tax = purchase price × sales tax rate. Adding the sales tax to the original purchase price gives the total price paid with tax.

Given that, a rake was marked up 25% from an original cost of $8.80.

25% of the original cost of $8.80 is

0.25×8.80 =$2.2

So the marked up price was 8.80+2.20

= $11

He then paid an additional 3% in sales tax, that is

11 + 0.03×11 = $11.33

Therefore, the total cost of the rake is $11.33.

Step-by-step explanation:

Answer:

That would be -2n - 1.

Answer:

-2n - 1

Step-by-step explanation:

You have to combine like term which would be 4n,n,and 7n.

Since n doesn't have a variable just add a one in front. So now the equation would be

1n+4n-7n That equation equals -2n

Now just add the remaining number

So that makes the answer -2n -1
