A roller coaster accelerated from rest to 55 m/s by the time it reached the first hill. The roller coaster took 15 seconds to climb to the top of the hill. What was the acceleration of the coaster?

Answers

Answer 1

Answer:

I believe the acceleration is 3.66666666667 m/s

Step-by-step explanation:

Acceleration formula: a = vf - vi / t

Initial velocity: 0 (I believe it was 0, as it wasn't moving in the beginning)

Final velocity: 55 m/s

Time: 15 s

Substituting values: 3.66666666667 = 55 - 0 / 15

Carlita is flying a kite at the beach. She wants to know the altitude of the kite when she uses 25 yards of string at an angle of elevation of 56°. Find the altitude of Carlita's kite to the nearest hundredth.
13.98 yards


20.73 yards


30.16 yards


37.06 yards

Please Answer as soon as you can I am giving 50 points!

Answers

Answer:

Step-by-step explanation:

13.98

The altitude of Carlita's kite to the nearest hundredth should be considered as the 13.98 yards when she uses 25 yards of string at an angle of elevation of 56.

Calculation of the altitude of Carlita's kite:

Since she uses 25 yards of string at an angle of elevation of 56°

So we know that

cos 56 degrees = 0.5592

Now the altitude is

= (25) (0.5592)

= 13.98 yards

We basically multiplied these two so that the altitude should come.

hence, the first option is correct.

5 STARS 20 foot ladder is leaning against the side of a building the bottom of the ladder is 4 feet from the wall the bottom of the ladder is 4 feet from the wall how many feet above the ground does the ladder touch the wall

Answers

Answer:

400

The ladder is the hypotenuse of a right triangle. The 2 feet from the wall on the ground is one side, the distance up the wall is another side.

In a right triangle, the square of the hypotenuse is the sum of the squares of the other two sides. This is called the Pythagorean Theorem. In equation form:

c^2 = a^2 + b^2

Substitute the known values:

20^2 = 2^2 + b^2

Square the numbers:

400 = 4 + b^2

Subtract 4 from both sides:

b^2 = 400 - 4 = 396

Take the square root:

b = sqrt(396) = 19.9 (rounded) feet

Check:

20^2 ?= 2^2 + 19.9^2

400 ?= 4 + 396.01

400 ?= 400.01 (off just a bit due to rounding)

Find a positive and a negative coterminal angle for 50 degrees

Answers

Answer: To find the coterminal angle of a 50° angle, add 360°. It would follow that 50°+360°=410°. A 410° angle is illustrated below. From the graphical representation of the angle, we can conclude that these two angles do indeed share the same terminal side, meaning they are coterminal.

Step-by-step explanation:

The positive and negative coterminal angle for 50 degrees are 410 degrees and -310 degrees respectively.

What is coterminal angle?

'Coterminal angles are the angles that have the same initial side and share the terminal sides.'

According to the given problem,

To find positive coterminal angle, we have to add 360 degrees to it,

⇒ 50 + 360 = 410 degrees.

To find negative co terminal angle, we have to subtract 360 degrees from it,

⇒ 50 - 360 = -310 degrees.

Hence, we can conclude that 410 degrees and -310 degrees are the coterminal angle for 50 degrees.

Your friend says that the table represents an exponential function because y is multiplied by a constant factor. Is your friend correct? Explain.
A.Yes. Because y is multiplied by a constant factor, the function is exponential.
B.Yes. Because y increases by greater amounts as x increases, the function is exponential.
C.No; Because y is multiplied by a constant factor, the function is not exponential.
D. No; Because x increases by different amounts, the function is not exponential.
x: 0,1,3,6
y: 2,10,50,250

Answers

Answer:

C.No; Because y is multiplied by a constant factor, the function is not exponential.

Step-by-step explanation:

For a set of number to be exponential, there is need for it to show a logical increase of a given time frame when the set of number is multiplied by a constant factor. In the table given, though the Y function is multiplied by a constant factor, the increase of the function is irregular so therefore cannot be said to be exponential.

The graph of 3x - 5y = 12 is shown on the grid. Which ordered pair is in the solution set of 3x - 5y 2 12? es ) A) (0,5) B) (5,0) © (-3,5) D) (-5,3)​

Answers

Answer:

i think itz C

Step-by-step explanation:

The required ordered pair is (5,0) in the solution set of the given inequality 3x - 5y ≥ 12. The correct answer would be option (B).

What is inequality?

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

The given graph of 3x - 5y = 12 is shown on the grid.

To find the solution set of 3x - 5y ≥ 12, we need to shade the region of line 3x - 5y = 12 since it represents all the points that make the inequality true.

When all the given points are drawn in the graph, then we get the ordered pair (5,0) in the solution set of the given inequality.

Thus, the required ordered pair is (5,0) in the solution set of the given inequality 3x - 5y ≥ 12.

Therefore, the correct answer would be an option (B).

Answer:

O No solution

Step-by-step explanation:

2x +2 = 2(x+3)

Distributer the 2 on the right side.

2x + 2 = 2x + 6

Subtract 2x from both sides.

2 = 6

2 = 6 is a false statement.

Since we did two legal steps to solve the equation, and we ended up with a false statement, that means this equation has no solution.
