In 1979, the price of electricity was $0.05 per kilowatt-hour. The price of electricity has increased at a rate of approximately 2.05% annually. If t is the number of years after 1979, create the equation that can be used to determine how many years it will take for the price per kilowatt-hour to reach $0.10. Fill in the values of A, b, and c for this situation. Do not include dollar signs in the response.
c=A(b)^x

Answers

Answer 1

The equation that can be used to determine the number of years it would take for the price to be $0.10 is 0.10 = 0.05(1.0205)^t.

What is the equation that models the increase?

The equation that would be used is an exponential equation. An exponential equation is used because the rate of increase is a compound growth.

Exponential equations usually have this form: FV = PV( 1 + r)^t

Where:

FV = future value PV = present value r = rate of growth t = time

0.10 = 0.05(1.0205)^t.

Takashi Caldwell has health insurance that pays 80 percent of coverage charges after a $150 deductible. She received a statement for $350 of covered charges. How much will Takashi have to pay?

Answers

Subtract the deductible from the total:

350 - 150 = 200

Takashi then needs to pay 20% of what is left.

200 x 0.20 = 40

Takashi has to pay the 150 deductible plus 40 for a total of $190

Square OPQR is inscribed in triangle ABC. The areas of △AOR, △BOP, △CRQ are 1, 3, and 1, respectively. What is the area of square OPQR?

Answers

Answer:

9 units²

Step-by-step explanation:

We know that ΔCRQ and ΔBOP are right triangles because RQ and OP are perpendicular to CB.

ΔAOR must also be a right triangle because ∠AOR = ∠OBP and ∠ARO = ∠RCQ.

Because of the Angle-Angle-Angle theorem, we know that ΔAOR ≅ ΔBOP ≅ ΔCRQ.

AR/AO = OP/PB

3(1/2)(AR)(AO) = (1/2)(OP)(PB)

PB = 6, OP = 3

3 x 3 = 9 units²

The area of square OPQR is 9 units².

Calculation of the area of square:

Since

ΔCRQ and ΔBOP are right triangles since RQ and OP are perpendicular to CB.

Also,

ΔAOR must also be a right triangle due to ∠AOR = ∠OBP and ∠ARO = ∠RCQ.

So it can be like

AR/AO = OP/PB

3(1/2)(AR)(AO) = (1/2)(OP)(PB)

PB = 6, OP = 3

= 3 x 3

= 9 units²

hence, The area of square OPQR is 9 units².

What is the area of the logo?​

Answers

Answer:

[tex]the \: area \: of \: the \: logo \: is \: {91cm}^{2} [/tex]

Step-by-step explanation:

To determine the area of the logo you have to calculate the area of the triangle and the square that comform it and then add the four areas.

Area of the square.

To calculate the area of the square you have to calculate the square of one of its sides, following the formula:

[tex]a = {a}^{2} [/tex]

Where "a" is the length of one of its side.

The side length of the square is a=7cm, so its area will be:

[tex]asquare = {7}^{2} \\ asquare = {49cm}^{2} [/tex]

Area of the triangles.

The three triangles are equal, they have a base equal to the side of the square, i.e. with a length of 7cm, and their height is h=4cm.

To calculate the area of one triangle, you have to multiply its base by its height and divide by 2, following the formula:

[tex]a = \frac{b.h}{2} \\ a = \frac{7.4}{2} \\ a = \frac{28}{2} \\ a = {14cm}^{2} [/tex]

The area calculated the correspond to one triangle, since all triangles are congruent, you have to multiply the said area by 3 to determine the area of three figures:

[tex]atriangles = 3a \\ atriangles = {42cm}^{2} [/tex]

Now that the area of all shape are calculated, you have to add them to determine the area of the logo:

[tex]alogo = asquare + atriangle \\ alogo = 49 + 42 \\ alogo = {91cm}^{2} [/tex]

Answer:

(7×7)+3(1/2×7×4)

49+42

The circumference of the hub cap of a tire is 73.79 centimeters. Find the area of this hub cap. Use 3.14 for π. Use pencil and paper. If the circumference of the hub cap were​ smaller, explain how this would change the area of the hub cap.
The area of this hub cap is about __ square centimeters.

Answers

Answer:

433.5 cm²

Step-by-step explanation:

The formula for circumference is C = 2πr, where r is the radius.

Here, C = 2πr = 73.79 cm.  Solving this for the radius, r, we get:

     73.79 cm

r = ---------------- = 11.75 cm

        2(3.14)

Then the area of the hubcap is A = πr², or, in this case,

A = 3.14(11.75 cm)²  =  433.5 cm²
