Solve the absolute value equation. If no solution write NO SOLUTION.<br> -{2x + 3] + 8<br> 12
Natasha2012 [34]

Answer:

If problem is "-|2x+3|+8=12"

then there is (<em>no solution.)</em>

Step-by-step explanation:

Let's solve your equation step-by-step.

−|2x+3|+8=12

Step 1: Add -8 to both sides.

−|2x+3|+8+−8=12+−8

−|2x+3|=4

Step 2: Divide both sides by -1.

−|2x+3|=4

   -1       -1

|2x+3|=−4

Step 3: Solve Absolute Value.

|2x+3|=−4

No solutions Because absolute value is less than 0.

PLEASE HELP!!! I am struggling

The ball will be at height 19 feet first at 0.7 sec and then at 1.42 sec.

<u>Explanation:</u>

We need to find the time at which the ball will be at height 19 feet.

Equation:

h = 3 + 34t - 16t²

19 = 3 + 34t - 16t²

16 = -16t² + 34t

-16t² + 34t - 16 = 0

On solving the equation, we get

t1 = 0.7 s and t2 = 1.42s

Therefore, the ball will be at height 19 feet first at 0.7 sec and then at 1.42 sec.

On March 24, 1989, the Exxon Valdez oil tanker ran aground and leaked millions of gallons of oil into Prince William Sound. The
Tema [17]

Answer:

592 hours

Step-by-step explanation:

Given

Area = 11000m^2

Radius = 0.10m/h

Required

Determine the time taken to cover the area

Since, the oil formed a circular pattern; the question will be answered using area of a circle

Area = \pi r^2

Let t represent the time take to cover 11000m²;

The relationship between these parameters is:

11000 = \pi * (0.10t)^2

Substitute 3.14 for π

11000 = 3.14 * (0.10t)^2

Divide both sides by 3.14

\frac{11000}{3.14} = \frac{3.14 * (0.10t)^2}{3.14}

\frac{11000}{3.14} =(0.10t)^2

3503.18471338 = (0.10t)^2

Take square root of both sides

\sqrt{3503.18471338} = \sqrt{(0.10t)^2}

\sqrt{3503.18471338} = 0.10t

59.1877074516 = 0.10t

Divide both sides by 0.10

\frac{59.1877074516}{0.10} = \frac{0.10t}{0.10}

\frac{59.1877074516}{0.10} = t

591.877074516 = t

t = 591.877074516

t = 592\ hours <em>(</em><em>Approximated)</em>

<em>Hence, it'll take approximately 592 hours to cover the given area</em>
