Multiply 7x6 since when using pemdas, multiplication and division can be inverted, i.e. if multiplication is before division then you multiply and vice versa.

Hope this helps!

Aaron’s mother purchases a new computer for $1750. If she claims a linear depreciation (loss of value) on the computer at a rate

kirill [66]

After 8 years the value of the computer to be $0 if the Aaron’s mother purchases a new computer for $1750.

<h3>What is a sequence?</h3>

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

We have:

Aaron’s mother purchases a new computer for $1750. If she claims a linear depreciation (loss of value) on the computer at a rate of $250 per year.

The above problem can be solved using concept of arithmetic sequence

The starting value = $1750

After one year = 1750 - 250 = $1500

After second year = 1500 - 250 = $1250

Common difference = 1500 - 1750 = -250

a(n) = 1750 + (n - 1)(-250)

a(n) = 0 (final value is zero given)

0 = 1750 + (n - 1)(-250)

n - 1 = 7

n = 8 years

Thus, after 8 years the value of the computer to be $0 if the Aaron’s mother purchases a new computer for $1750.

Victor was having a hard time deciding which new vehicle he should buy. He decided to make the final decision based on the gas e

Amanda [17]

Answer:

Victor should buy Legend because it has a better unit rate

<em></em>

Step-by-step explanation:

See attachment for complete question.

To determine which car has more gas efficiency, we have to calculate the slope of each car.

Vehicle 1: Legend

Take any two corresponding points from the table

$(x_1,y_1) = (4,72)$

$(x_2,y_2) = (12,216)$

The slope is then calculated using;

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{216 - 72}{12 - 4}$

$m = \frac{144}{8}$

$m = 18$

<em>This implies that this vehicle (legend) travels 18 miles per gallon of gas</em>

Vehicle 2: Supreme

Take any two corresponding points from the graph

$(x_1,y_1) = (0,0)$

$(x_2,y_2) = (15,250)$

The slope is then calculated using;

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{250 - 0}{15 - 0}$

$m = \frac{250}{15}$

$m = 16.7$

This implies that this vehicle (supreme) travels 16.7 miles per gallon of gas

<em>Base on the calculations above, Victor should buy Legend because it has a better unit rate</em>

Find one terminating decimal and one repeating decimal between -1/2 and -1/3

Masteriza [31]

Terminating decimal:
-0.45
Repeating decimal:
-2/9 = -0.22222222... or -0.2 with an overline over the 2(that's how you notate a repeating decimal)

The formula v=√ 2gh gives the velocity v, in feet per second, of an object when it falls h feet accelerated by gravity g, in fee

kvasek [131]

Hi there!

$\large\boxed{36 \text{ feet}}$

v = √2gh

Plug in the given velocity and acceleration due to gravity:

48 = √2(32)h

Square both sides:

2304 = 2(32)h

Simplify:

2304 = 64h

Divide both sides by 64:

h = 36 feet.
