The cost in dollars, y, to participate x days in a bike tour is a linear function. Lin's bike tour is described by the equation

y = 5x + 50. The cost of Max's bike tour is $120 for a 14-day bike tour. If both Lin and Max take 14-day tours, whose bike tour costs less? Lin Max They cost the same amount

Answer:

They cost the same amount

Step-by-step explanation:

Given

Lin: y = 5x +50 where x = 14

Max: \$120 for 14 days

Required

Which is less expensive?

Max charges has been given from the question as; $120 for 14 days.

To determine Lin's, we simply substitute 14 for x in y = 5x +50

y = 5  * 14 + 50

y = 70 + 50

y =120

The above result of y shows that Max charges for 14 days is also $120.

<em>Hence, they (Lin and Max) cost the same because they both equal to $120 for 14 days</em>

First, we plug in the numbers.

$40 = P(4%)(2)

4% = 0.04

40 = P * 0.04 * 2

Divide each side by 2

20 = P * 0.04

Divide by 0.04

P = 500

Lets check it!

500 * 0.04 * 2 = 40

500 * 0.04 = 20

20 * 2 = 40

40 = 40

BRAINLIESTT ASAP! PLEASE HELP ME :)

Answer: A) none of the equations are identities

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

Part 1

Plug in theta = 0

sin(theta+pi/2) - cos(theta+pi/6) = 2*cos(theta) - sin(theta)

sin(0+pi/2) - cos(0+pi/6) = 2*cos(0) - sin(0)

1 - sqrt(3)/2 = 2*1 - 0

0.13 = 2

which is a false equation

So we do not have an identity in equation 1.

-------------------------------------------

Part 2

Plug in theta = 0

sin(theta+pi/6) + cos(theta+pi/3) = (sqrt(2)/3)*sin(theta) + 2*cos(theta)

sin(0+pi/6) + cos(0+pi/3) = (sqrt(2)/3)*sin(0) + 2*cos(0)

1/2 + 1/2 = 0 + 2

1 = 2

which is also false

This is not an identity either.

Find the missing terms in the arithmetic sequences <br> a). -45, _ , _ , _, -39 <br> b) -34,_,_,77
ANTONII [103]

Answer:

a) -45, <u>-43.5, -42, -40.5</u>, -39. f(n) = -45 + 1.5(n-1)

b) -34, 3, 40, 77. f(n) = -34 + 37(n-1)

Step-by-step explanation:

The explicit formula for an arithmetic formula can be defined as: f(n) = f(1) + d(n-1).

Where n is the number, and d is the common difference.

2. The angle of elevation of the top of a vertical
frozen [14]

Answer: 15.44 m

Step-by-step explanation:

We can think this as two triangle rectangles.

In both cases, the adjacent cathetus is 120m.

When the angle is 32°, the opposite cathetus will be the height of the cliff.

When the angle is 37°, the opposite cathetus will be the heigth of the cliff plus the height of the flagpole.

Then we need to compute both of them and calculate the difference.

We can use the trigonometric relation:

Tan(θ) = (opposite cathetus)/(adjacent cathetus)

in this case we have:

Tan(32°) = (height of the cliff)/(120m)

Tan(32°)*120m = height of the cliff = 74.98m

Now we can use the other angle to compute:

Tan(37°) = (heigth of the cliff + heigth of the flagpole)/120m

Tan(37°)*120m = heigth of the cliff + heigth of the flagpole = 90.42m

Then the height of the flagpole will be:

H = 90.42m - 74.98m = 15.44 m
