is it A, B, C or D? (30 points)

Answer:

to differential calculus, because I don't know how to answer this question without

using it.

We're told that Jason's height above the water is  H(t) = -16t² + 16t + 480 .

We can observe many things from this equation:

-- Up is the positive direction; down is the negative direction.

-- The acceleration of gravity is 32 ft/sec² .

-- Jason jumps upward from the cliff, at 16 ft/sec .

-- The cliff is 480-ft above the water.

(This tells us why the question is only concerned with his maximum height,

and then it ends ... 480-ft is one serious cliff, and what happens after the

peak of his arc is too gruesome to contemplate.)

In any case, his vertical velocity is the first derivative, with respect to time,

of his height above the water.

        V = -32 t + 16

At the peak of his arc, where gravity takes over, his velocity changes from

upward to downward, and it's momentarily zero.

                                          0 = -32t + 16

Add  32t  to each side:    32t = 16

Divide each side by  32:      t = 1/2 second

His height at that instant is     H(0.5) = -16(0.5)² + 16(0.5) + 480 =

                                          4-ft above the cliff,  484-ft above the water,

and then he begins falling from that altitude.

The duration of his dive is      484 = 16 t²

                                                  t = √(484/16) = 5.5 seconds

and he hits the water at      V = a t = (32) x (5.5) = 176 ft/sec = exactly 120 mph

Step-by-step explanation:

The sum of the squares of the two smaller sides is equal to the square of the third side.

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.

There are many types of triangles such that right angle triangle, equilateral triangle, and much more.

Given,

Δabc is a right-angle triangle

By Pythagoras theorem

Hyp² = perp² + base²

Here

Hyp = c (longer side)

Pepe and base = a and b

So,

c² = a² + b²

(Longer side)² = a² + b²

Hence, The sum of the squares of the two smaller sides is equal to the square of the third side.

The sum of the squares of the two smaller sides is equal to the squares of the third side.

Option B is the correct answer.

Given,

The triangle above is a right triangle with side lengths a = 7 in, b = 24 in, and c = 25 in.

We need to see which option is true.

It states that in a right-angled triangle the square of the hypotenuse is equal to the sum of the squares of the other two sides.

We have,

The triangle above is a right triangle with side lengths:

a = 7 in

b = 24 in

c = 25 in

Here c = hypotenuse.

So applying the Pythagorean theorem.

c^2 = a^2 + b^2

25^2 = 7^2 + 24^2

625 = 49 + 576

625 = 625

We see that the given values satisfy the Pythagorean theorem.

Thus the sum of the squares of the two smaller sides is equal to the squares of the third side.

Option B is the correct answer.

Answer:

The answer to the system of equations is x = 2 and y = -1

Step-by-step explanation:

We can substitute the variables and see how they work with the equations.

2 (-1) = (2) - 4

-2 = 2 - 4

-2 = -2

4 (2) + 3 (-1) = 5

8 + (-3) = 5

8 - 3 = 5

5 = 5
