Answer: C.) - 896

Step-by-step explanation:

Given the explicit formula :

An = 7 × (-2)^(n-1)

The 8th term of the geometric sequence using the formula will be :

n = 8

A8 = 7 × (-2)^(8-1)

A8 = 7 × (-2)^7

A8 = 7 × (-128)

A8 = - 896

$3.00 marked up 72%<br><br>(please show your work!!)<br><br>thank you❤️❤️​

<h3>Answer:  $5.16</h3>

==================================================

Work Shown:

72% = 72/100 = 0.72

72% of $3.00 = 0.72*3.00 = 2.16

The price increases by $2.16 to get the final answer of 3.00+2.16 = 5.16 dollars

-------

We can find this answer through this alternative route:

1.72*3 = 5.16

The multiplier 1.72 represents an increase of 72% since 1.72 = 1 + 0.72 = 100% + 72% = 172%

Answer: See the picture attached.

Step-by-step explanation:

Given the following mixed numbers:

-2\frac{3}{4}\\\\-4\frac{1}{2}

You need to convert them to decimal numbers. The steps to do this are shown below:

1. Divide the numerator of the fraction by the denominator.

2. Add the quotient obtained to the whole number part.

Then:

-2\frac{3}{4}=-(2+0.75)=-(2.75)=-2.75\\\\-4\frac{1}{2}=-(4+0.5)=-(4.5)=-4.5

Therefore, the point is:

(-2.75,-4.5)

Where -2.75 is the x-coordinate and -4.5 is the y-coordinate.

Knowing this, you can plot it on the coordinate plane, as you can see in the picture attached.
