A central angle of circle P is angle
The measure of RU is degrees.

Answers

Answer:

Step-by-step explanation:

RU=59 degrees

angle = TPQ

Central angle of circle P is a angle equals to 121° and 73°.

The measure of arc RU is 59 degrees

What is circle?

" A circle is closed two dimensional shape , whose all points on the surface are equidistant from its center."

Definition of arc measure

"In a circle, the degree measure of an arc is equals to the central angle present in the included arc."

According to the question,

∠TPU and ∠UPR are supplementary angles.

Given , ∠UPR = 59°

Therefore,

∠TPU = 180° - 59°

         = 121°

∠TPQ + ∠QPR = 180°

∠QPR = 107°

Therefore ,

∠QPR = 180° - 107°

          = 73°

As per the definition of arc measure, we conclude

The measure of arc RU is equals to 59degrees.

Hence, central angle of circle P is a angle equals to 121° and 73° and

measure of arc RU is 59 degrees.

Find the equation of a line perpendicular to y=-3x-1 that contains the point (-1,1). Write the equation in slope intercept form.

Answers

Answer:

y = [tex]\frac{1}{3}[/tex]x + 1 [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

y = -3x - 1

1. Perpendicular line needs the opposite (reciprocal) of the slope.

             reciprocal of -3 is -1/3, slope 1/3.                    y = 1/3x + b

2. Now find the b (y-intercept).                                     1 = 1/3(-1) + b

                                                                                       1 = -1/3 + b

                                                                                 + 1/3  +1/3

                                                                                    1 1/3 = b

Answers

Answer:

m<GKH + m<HKI = 180; m<HKI + m<IKJ = 180 - Angles forming a linear pair sum to 180

m<GKH + m<HKI = m<HKI + m<IKJ - Subsitution

m<GKH = m<IKJ - Algebra

<GKH ≅ <IKJ - Definition of congruence

Step-by-step explanation:

Angles that form a linear pair are supplementary because together they make a straight line. So, they must sum to 180.

In statement 2, m<HKI + m<IKJ replaces 180 degrees. This is allowed because m<HKI + m<IKJ is equivalent to 180 degrees, so it can be substituted.

In statement 3, m<HKI is subtracted from both sides. This is allowed through the property of equality, which is a part of algebra.

The definition of congruency is that two shapes that are equal are congruent. So if m<GKH = m<IKJ, then they must be congruent as well.

3. Kara joins a movie club. She receives 8 free DVDs when she joins. She must buy 2 DVDs a month.



What is the minimum number of DVDs she buys if she is in the club for one year?

Write an equation that represents the minimum number of DVDs y that Kara buys after x months.

If Kara plans to leave the club after buying 50 DVDs, how many months will she be a member?

Answers

Answer:

Answer to part one of the problem = 24 DVD's

Answer to part two of the problem = 2 · x = y

Answer to part three of the problem = 25 months

Step-by-step explanation:

Part 1:

She buys 2 DVD's a month and there are 12 months in a year.

2 x 12 = 24

The minimum amount of DVD's she buys if she is in the club for one year is 24 DVD's

Part 2:

y = minimum number of DVD's bought after x years

x = amount of months

so the equation would look like this:

2 · x = y

Part 3:

If she sticks to the minimum of buying 2 DVD's a month then we can create this equation:

50 / 2 = 25

she will be a member for 25 months or 2 years and 1 month.

Interpret your answer.
The demand is going by % per 1% increase in price at that price level.

Use the elasticity to calculate the price that gives a maximum weekly revenue.
dollars per orange

Find this maximum revenue.
dollars of revenue

Answers

Answer: See Explanation

Step-by-step explanation:

The price elasticity of demand will be calculated as:

q = 860 − 20p.

dq/do = -20

p = 38

Elasticity E(p) = (p/q) × dq/dp

= [38 /(860 - 20p)] × (20)

=38 × 20/(860 - 760)

= 7.6

Therefore, the price elasticity of demand when the price is $38 per orange is 7.6

Revenue = price × quantity

= p × q

= p × (860 − 20p)

= 860p - 20p²

Differentiating with respect to p

= 860 - 40p

40p = 860

p = 860/40

p = 21.50

Maximum Revenue = 860p - 20p²

= 860(21.50) - 20(21.50)²

= 18490 - 9245

= 9245

Word problem: Tuition fees for California State University were $5,131 during the 2010-2011 academic year. Historically, tuition has increased at an 8% per year rate. Use the formula from Problem 83 to find what the tuition was 20 years ago and 30 years ago. Hint: First solve for P, then substitute the given value for F. Round to the nearest dollar. (equation in #83 to use here is F=P(1+r)² where F is the future price of an item priced at P dollars, r is the inflation rate expressed as a decimal, and t is the time in years)​
The given answers for this problem are: 20 years ago, tuition was $1,101 and 30 years ago tuition was $510.

Answers

Answer:

For this problem we have:

Initial value  P = $5131Increase rate r = 8% or 0.08Time 20 years ago t = -20          30 years ago t = -30

Find the value of F using the formula and substitute the values:

F(t) = P(1 + r)^tF(-20) = 5131(1 + 0.08)^(-20) = 1100.84685219 ≈ $1101

and

F(-30) = 5131(1 + 0.08)^(-30) = 509.905093313 ≈ $510
