You ride through some wet paint on your bike, creating a red
spot on the tire. Write a cosine equation to model the height
of the red spot over the distance you ride.

• Your bike tire has a radius (r) of 13 inches

• The period is the circumference of the tire (2 πr)

• Start the cycle when the spot is at the top of the tire

Answers

Answer:B

y=13cos(1/13x)+13

Step-by-step explanation:

The cosine equation to model the height of the red spot over a distance you ride is y = 13 cos (x/13) + 13. Then the correct option is B.

What is a cosine Function?

It is a function that repeats itself in a particular time interval.

You ride through some wet paint on your bike, creating a red spot on the tire.

Write a cosine equation to model the height of the red spot over the distance you ride.

Your bike tire has a radius (r) of 13 inches.

The period is the circumference of the tire (2πr).

The cosine equation is given as

y = A cos (Bx + C) + D

Where

A = the amplitude

B = time period

C = phase difference

D = shifting of central line

Then we have the diagram

A = 13

B = 1/13

C = 0

D = 13

Then the equation will be

[tex]\rm y = 13 \cos (\dfrac{1}{13}x - 0 ) + 13\\\\y = 13 \cos (\dfrac{x}{13} ) + 13[/tex]

Hope has driven 19 miles. She averaged 47 miles per hour. How many more hours must she drive to travel a total of 739 miles?
Pls help I only have until 11:59

Answers

I am coming to the rescue hehehe

So, she has drove 19 miles already so
739 - 19 = 720
720/47= 15.320 ~ about 15 hours
15 hours and 20 minutes
The hours you would write is 15
739-19/47
739-19=720
720/47=15.319
15.319 rounded = 15 hours and 29 minutes

Which algebraic expression represents “the quotient of 7 and a number”?

Answers

Answer: D

Step-by-step explanation: its best you can get to the a quotient (from Latin: quotiens "how many times", pronounced) is a quantity produced by the division of two numbers. The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division (in the case of Euclidean division), or as a fraction or a ratio (in the case of proper division). For example, when dividing 20 (the dividend) by 3 (the divisor), the quotient is 6 in the Euclidean division sense, and 62/3 in the proper division sense.

Find the ten missing angles labeled in the diagram. Line a is parallel to line b. The measures of two angles are given.​

Answers

Answer:

m∠3 = 112°     m∠5 = 38°     m∠6 = 68°    m∠8 = 74°

You do the others

Step-by-step explanation:

Facts you need to solve this problem.

1.  Vertical angles are congruent

2.  Alternate interior angles are congruent when lines are parallel

3.  Sum of the measures of the angles of a triangle is 180

4.  Adjacent angles are supplementary when two lines intersect

m∠3 = 112°   (Reason 1 above)

m∠6 = 180 - 112 = 68°   (Reason 4)

m∠6 + m∠5 + 74 = 180°  (Reason 3)

68 + m∠5 + 74 = 180

142 + m∠5 = 180

m∠5 = 38°

m∠8 = 74°  (Reason 2)

That gives you a start, so I will let you find all the others.  OK?  I know you don't want to do that, but you need to be able to do this type of problem.  Now, go for it!!

A growth medium is inoculated with 1,000 bacteria, which grow at a rate of 15% each day. What is the population of the culture 6 days after inoculation?

y = 1,000(1.15)6; 2,313 bacteria
y = 1,000(1.15)7; 2,660 bacteria
y = 1,000(1.5)5; 7,594 bacteria
y = 1,000(1.5)6; 11,391 bacteria

Answers

Answer:

A

Step-by-step explanation:

The population of the culture 6 days after inoculation is 2,313.

Correct option is (A).

What is Compounding?

When interest is earned and then reinvested, the total interest on the principle is calculated using compounding. It causes assets or capital to increase exponentially for investors.

As per the given data:

Number of bacteria initially (P) = 1000

Growth rate of the bacteria = 15% each day

Growth rate of the bacteria in decimal (r) = 0.15

Number of days (n) = 6

The bacteria is growing each day with 15% each day, hence it is compounding.

The population of the culture 6 days after inoculation (y):

[tex]y = P (1+r)^t[/tex]

[tex]y = 1000 (1+0.15)^6[/tex]

[tex]y = 1000 (1.15)^6[/tex]

y = 2,313

Hence, The population of the culture 6 days after inoculation is 2,313.
