Answer:

Step-by-step explanation:

You want functions for the velocity v(t) and height h(t) of a ball thrown upward at 38 m/s from a height of 1.8 m. The acceleration is -9.8 m/s².

This sort of problem is usually discussed in a physics course. The relation between acceleration, velocity, and position is ...

  velocity is the rate of change of position

  acceleration is the rate of change of velocity

Then the inverse relations are ...

  h(t) = ∫v(t)dt +h(0)

  v(t) = ∫a(t)dt +v(0)

When position is measured in one dimension (up = positive), these have the standard formulas:

  v(t) = g·t + v(0)

  h(t) = 1/2g·t² +v(0)·t +h(0)

Filling in the given values (g = -9.8, v(0) = 38, h(0) = 1.8), we have ...

  v(t) = -9.8t +38 . . . . . . . . . . . . meters per second

  h(t) = -4.9t² +38t +1.8 . . . . . . meters

Factoring the equation f(x) = 4x^2 - 3x - 10 gives f(x) = (4x - 5)(x + 2)

From the question, we have the following parameters that can be used in our computation:

f(x) = 4x^2 - 3x - 10

Expand the equation

So, we have the following representation

f(x) = 4x^2 + 8x - 5x - 10

Factorize the equation

So, we have the following representation

f(x) = 4x(x + 2) - 5(x + 2)

Factor out x + 2 from the equation

So, we have the following representation

f(x) = (4x - 5)(x + 2)

Hence, the factored exrpression is f(x) = (4x - 5)(x + 2)

The sum of the given two polynomials (x²-7x+14) + (x²+10x-4) is 2x² + 3x + 10

To find the sum of the polynomial expression, we need to add the like terms of the two polynomials.

The first polynomial is x²-7x+14 and the second polynomial is x²+10x-4. We can combine the terms with x² to get 2x².

Then, we can combine the x terms to get 3x.

Finally, we can combine the constant terms to get 10.

Therefore, the sum of the two polynomials is:

2x² + 3x + 10

In summary, we can find the sum of two polynomials by adding the like terms of the polynomials. We group the terms with the same degree of x, add them up and simplify the expression by combining the like terms.

1) Note that when x = 7, then the second coordinate is y =  112.8. (Option d)

2) the approximate value of where x =4 given the function above is 3 (Option a)

A) by logical deduction,  if on the table, x and y values are given, then they retain those positions as coordinates on the graph. Hence, when x = 7, then the second coordinate is y =  112.8.

b) to find the approximate value of y for x = 4, we can use the equation given:

log y = 0.75821x + 0.03442

Substituting x = 4:

log y = 0.75821(4) + 0.03442

The area was approximately 430.365 square meters.

To start, let's recall the formula for finding the area of a triangle. The formula is:

Area of a triangle = (base x height) / 2

To do that, we can use Heron's formula. Heron's formula states that the area of a triangle can be found using its sides, a, b, and c, where s is the semi-perimeter of the triangle (half of the perimeter):

Area of a triangle = √(s(s-a)(s-b)(s-c))

where

s = (a+b+c)/2

Now, let's apply Heron's formula to our problem.

We know that the sides of the triangle are 75.6m, 56.7m, and 52.5m. We can add them together and divide by 2 to get the semi-perimeter:

s = (75.6 + 56.7 + 52.5) / 2

s = 92.4

Next, we can substitute the values of a, b, and c into the formula:

Area of a triangle = √(92.4(92.4-75.6)(92.4-56.7)(92.4-52.5))

Area of a triangle = √(92.4(16.8)(35.7)(39.9))

Area of a triangle = √(185623.66256)

Area of a triangle ≈ 430.365m²

= 99 degrees.

So the area of the triangle with sides measuring 75.6m, 56.7m, and 52.5m, and a height of 42m, is approximately 430.365 square meters.

The measure of the angles ∠OAT, angle ∠OTA, side AT, and side BT will be 90°, 34.5°, 5.82 units, and 5.82 units, respectively.

Given that:

TA and TB are tangents to O.

OA = 4 and ∠ATB = 69°.

Angle ∠OAT will be 90° because the tangent and radius intersect at a right angle.

Angle ∠OTA is half of the angle ∠ATB. Then we have

∠OTA = ∠ATB/ 2

∠OTA = 69° / 2

∠OTA = 34.5°
