To solve this question, we have to find the acceleration of the car first. Acceleration refers to the rate of change of velocity of an object with respect to time.
Acceleration [A] = [V0 - V1] / T
Where VO = Initial velocity and V1 = Final velocity T represent time.
V0 = O
V1 = 18
T = 8
A = [ 0 - 18] / 8 = - 2.25
A = - 2.25 M/S^2.
To find force, we are going to use the formula: F = MA
F = ?
M = 1550
A = - 2.25
F = 1550 * - 2.25 = 3487.5
Therefore, F = -3487.5 N

The solution set to 6 + 2n > 12 is n > 3. Which are the correct representations of this solution? Select two options.

Alina [70]

The correct representation of 6 + 2n > 12 (n > 3) is (3, ∞) and a number line with an open circle at +3 and being shaded from +3 to +5.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Given the equation::

6 + 2n > 12

Subtracting 6 from both sides:

6 + 2n - 6 > 12 - 6

2n > 6

Dividing by 2:

n > 3

The correct representation of 6 + 2n > 12 (n > 3) is (3, ∞) and a number line with an open circle at +3 and being shaded from +3 to +5.

yulyashka [42]

Answer:

$m=4$ or $m=\frac{4}{1}$

Step-by-step explanation:

To find slope we use the slope formula

$m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }$

Two points on the line we can classify are (3,4) and (4,8)

Natalie’s income statement for the month of October is shown. Natalie monthly income statement for October. Total wages are 3,00

rusak2 [61]

Natalie’s net income for the month of October is $1,930.

<h2>Net Income </h2>

The net income of a person is the income of the person that is left with him after deducting all of his\her expenses and deductions.

$\rm Net\ Income = Total\ salary - Total\ expenses - Deductions$

<h2 /><h2>Given to us</h2>

Natalie's monthly income statement for October. Total wages are 3,000 dollars.

Total expenses are 1,070 dollars.

<h3 /><h3>Natalie’s net income</h3>

the total wage Natalie is already given is $3,000, and her expenses as $1,070, while there are no deductions from his salary. therefore,

$\rm Natalie 's\ Net\ Income= Total\ salary - Total\ expenses - Deductions$

$=\$3,000 - \$1,070 -\$0\\= \$1930$

Hence, Natalie’s net income for the month of October is $1,930.
