Answers

Answer 1
X= 1.288 or just 1.29 is the correct answer. When you factor, set each factor equal to zero.
1. Move all terms to one side of the equation, usually the left, using addition or subtraction.
2. Factor the equation completely.
3. Set each factor equal to zero, and solve.
4. List each solution from Step 3 as a solution to the original equation.

Find the area of the figure. Use 3.14 for π.

Answers

Answer:

196.48m²

Step-by-step explanation:

AREA OF THE PICTURE = AREA OF TRIANGLE + AREA OF SEMI CIRCLE

Length of base of the triangle = 16m

Length of perpendicular height of triangle = 12m

Area of triangle = [tex]\frac{1}{2} *16*12 = 96m^{2}[/tex]

Length of diameter of semi-circle = 16m

Length of radius of semi-circle = [tex]\frac{16}{2} =8m[/tex]

Area of semi circle = [tex]\frac{\pi 8^{2}}{2} = \frac{64 * 3.14}{2} =\frac{200.96}{2} =100.48m^{2}[/tex]

AREA OF THE FIGURE = 100.48 + 96 = 196.48m²

Isabel wants to start saving more money so that she can purchase new clothes for college. She has $200 and will add $5 to her savings every day.

Which equation models Isabel's savings, where n represents each day?

Answers

Answer:

y = 5n + 200

Step-by-step explanation:

y = mx + b

$5 will be added every day, so 5 is the m and n is the x.

$200 is an extra cost that doesn't repeat, so it's the b.

When a gas is kept at a constant temperature and pressure on it changes, its volume changes according to the following formula, known as Boyle’s law

where P1 and V1 are the pressure (in atm) and the volume (in litres) at the beginning, and P2 and V2 are the pressure and the volume at the end. Find the final pressure P2 if V1 = 1.5 litres, P1 = 4.5 atm and V2 = 3.5 litres. Round to the nearest tenth of a atm.

Answers

Answer:  Approximately 1.9 atm

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

Work Shown:

[tex]P_1*V_1 = P_2*V_2 \ \text{ ... Boyle's Law}\\\\4.5*1.5 = P_2*3.5\\\\6.75 = P_2*3.5\\\\P_2*3.5 = 6.75\\\\P_2 = \frac{6.75}{3.5}\\\\P_2 \approx 1.92857142857142\\\\P_2 \approx 1.9\\\\[/tex]

If the volume is 3.5 liters, then the pressure is approximately 1.9 atm.

Note the increase in volume leads to the reduction of pressure, and vice versa. The two variables have an inverse relationship.

-----------

As a check,

[tex]P_1*V_1 = P_2*V_2\\\\4.5*1.5 \approx 1.9*3.5\\\\6.75 \approx 6.65\\\\[/tex]

We don't get the exact thing on both sides, but the two sides are close enough. We have rounding error due to P2 being not exact.

A more accurate check could be

[tex]P_1*V_1 = P_2*V_2\\\\4.5*1.5 \approx 1.92857*3.5\\\\6.75 \approx 6.749995\\\\[/tex]

which has the two sides much closer to one another. This helps us verify the answer.
