What is the horizontal asymptote of the function f (x)= x^2-25/2x^2 ?

Answer:

The function that describes the height of the ball in time is  [tex]h(t) = 32\cdot t -16.087\cdot t^{2}[/tex].

Step-by-step explanation:

Let suppose that ball experiments a free fall motion, which means that the ball is accelerated because of gravity and gravitational acceleration can be considered constant since height reached by the object is too small in comparison with the radius of the Earth. Therefore, we can assume that ball is accelerated uniformly.

Hence, the kinematic formula for the height of the ball ([tex]h(t)[/tex]), in feet, is described below:

[tex]h(t) = s + v\cdot t + \frac{1}{2}\cdot g \cdot t^{2}[/tex] (1)

Where:

[tex]s[/tex] - Initial height with respect to the ground, in feet.

[tex]v[/tex] - Initial velocity, in feet per second.

[tex]t[/tex] - Time, in seconds.

[tex]g[/tex] - Gravitational acceleration, in feet per square second.

If we know that [tex]s = 0\,ft[/tex], [tex]v = 32\,\frac{ft}{s^{2}}[/tex] and [tex]g = -32.174\,\frac{ft}{s^{2}}[/tex], then the function that describes the height of the ball in time is:

[tex]h(t) = 32\cdot t -16.087\cdot t^{2}[/tex] (2)

Answer:

$14.85

Step-by-step explanation:

8.98 + 3.27 + 1.5 = 13.75

13.75 x .08 = 1.1

13.75 + 1.1 = 14.85

Answer:

$14.85

Step-by-step explanation:

8.98 x.08= 0.7184

3.27 x .08= 0.2616

1.50 x .08= 0.12

8.98 + 0.72=  9.70

3.27 + .26= 3.53

1.50 + 12 =1.62

9.70+ 3.53 +1.62 = 14.85

Answer:

The number cubes needed when we have three cubes along each edge is 27 cubes

Step-by-step explanation:

The given parameters for the building of a cubic prism are;

The number of cubes used to build the 2 by 2 cube = 8 cubes

Let 'x' represent the length of each cube, we have;

The volume of a 2 by 2 cube = 2·x × 2·x × 2·x = 8·x³

Where x³ represents the volume of each cube

When we have three cubes along each edge, the total volume, becomes;

V = 3·x × 3·x × 3·x = 27·x³

The number cubes needed when we have three cubes along each edge, n = (The total volume of the cubes)/(The volume of each cube)

∴ The number cubes needed when we have three cubes along each edge, n = 27·x³/(x³/cube) = 27 cubes.

Answer:

Y= -4.5

Step-by-step explanation:

Hope this helps!

Answer:

y = -4.5

Step-by-step explanation:

6(y + 1.5) = -18

6y + 9 = -18

subtract 9 from each side of the equation:

6y = - 27

divide both sides by 6:

y = -4.5

Answer:

Lateral surface area = 360 cm²

Step-by-step explanation:

Given:

Dimension of small rectangle = (12 cm by 10 cm)

Find:

Lateral surface area

Computation:

Length =√9² + 12²

Length = √81 + 144

Length = 15 cm

Dimension of big rectangle = (15 cm by 10 cm)

Lateral surface area = Area of small rectangle + Area of big rectangle + Area  of slop rectangle

Lateral surface area = (L1 x B1) + (L x B) + (l x b)

Lateral surface area = (12 x 10) + (15 x 10) + (10)(9)

Lateral surface area = 120 cm² + 150 cm² + 90 cm²

Lateral surface area = 360 cm²

Answer:

[tex]\frac{x}{y}[/tex]45 long

Step-by-step explanation:

The total area of both the triangles is 56.25 square units.

When two triangles are similar, the reduced ratio of any two corresponding sides is called the scale factor of the similar triangles.

The space occupied by a flat shape or the surface of an object is called area.

Area = (1/2) × base × height

According to the given question.

We have a two triangles, which are similar to each other.

Let the length of the side DE in triangle DEF be x.

Since, ABC similar to DEF

⇒[tex]\frac{AB}{DE} =\frac{BC}{EF}[/tex]

⇒[tex]\frac{12}{x} =\frac{6}{4.5}[/tex]

⇒[tex]\frac{12(4.5)}{6} = x[/tex]

⇒[tex]2(4.5)=x[/tex]

⇒ [tex]x = 9[/tex]

Now, area of triangle ABC = [tex]\frac{1}{2}(6)(12)=36 square units[/tex]

Area of triangle DEF = [tex]\frac{1}{2} (9)(4.5)= 20.25square units[/tex]

Therefore,

The total area for both the triangles

= 36 + 20.25

= 56.25 square units

Thus option B is correct.

Answer:

14.90cm [a]

Step-by-step explanation:

To find x, we will apply " sine rule"

that is, [tex]sin[/tex]A/a=[tex]sin[/tex]B/b

here a= x A=90° B=70°anb b =14cm

so we input the values we have

x = 14/0.94

Answer:

10 in * 7in

Step-by-step explanation:

Given that :

Volume of block = 350 in³

Height of block = 5 inches

The dimension of block can be expressed cubic units

Volume of a rectangular prism :

V = length * width * height

Let ; length * width = B

350 = B * 5

B = 350 / 5

B = 70 in²

Possible dimension of B:

B = length *width

70 in² = 10 in * 7in

Hence, possible whole number dimension for the base = 10 in * 7in

Answer:

1: The highest score is 98, the lowest score is 74.

2: 55% of the scores are greater than 84

Step-by-step explanation:

Solution 1-1:

Starting from the top left and going from left to right row by row we compare the largest number we come across with the current number we are inspecting.

Starting with 92 then we look at 88, 92 is greater than 88 so we keep 92, next is 95, 95 is greater than 92 so we keep 95, next is 74, 95 is greater than 74 so we keep 95 and so on until we have compared all of the numbers. We are left with 98

Solution 1-2:

Using a similar method to finding the greatest number we go through the list of numbers in search of the smallest number. Starting with 92 we then look at 88, 88 is less than 92 so we keep 88. Next is 95, 88 is less than 95 so we keep 88. Then 74, 74 is less than 88 so we keep 74 and so on. We are left with 74

Solution 2:

There is a total of 20 numbers in the table. By comparing the numbers in the table to 84, we can determine that 11 numbers are greater than 84.

By dividing 11 by 20 we get 0.55 which is equal to 55%

Answer:

  24π cm²

Step-by-step explanation:

The radius and height of the cone are shown as 3 and 4, so we know the slant height is 5 (a 3-4-5 right triangle is formed by these dimensions). Then the total surface area of the cone is ...

  A = πr² + πrl = πr(r +l)

  A = π(3 cm)(3 cm +5 cm) = 24π cm² . . . . total area of the cone

Answer:

x = 9

Step-by-step explanation:

Formula

The secant and tangent lines bear the following relationship

(tangent line )^2 = the outside secant line * length of the whole line

Givens

tangent line = 15

outside secant line = x

length of whole secant line = x + 16

Solution

15^2 = x ( x + 16)

15^2 = x^2 + 16x

225 = x^2 + 16x

x^2 + 16x - 225 = 0

Answer and Discussion

The equation has two factors.

(x - 9)(x + 25) =0

x + 25 has no meaning. There cannot be a negative length in this level of geometry.

The answer is x - 9 = 0

x = 9

Answer:

Let n be the number of 25 cent stamps.Then, 28 - n must be the number of 29 cent stamps.Tim paid $7.60 the stamps.

0.25n + 0.29(28 - n) = 7.60

This means that n stamps at 25 cents a piece plus (28 - n) stamps at 29 cents a piece sum to $7.60.Solve for m.

0.25n + 8.12 - 0.29n = 7.60

-0.04n = -0.52

n = 13

So, Tim bought 13 25-cent stamps and 28 - 13 = 15 29-cent stamps

Answer: 16,21

Step-by-step explanation:

There are two ways you can solve this problem using substitution and elimination.

In this answer, I'm going to be using substitution.

First, you make two equations based on the information given.

The two equations are 0.15x+0.2y=6.6 and X+Y=37.

In the second problem subtract y to move it to the other side to get X=37-y.  

Now that you got x= make a new equation which should be 0.15(37-y)+0.2y=6.6 use distributive property to get 5.55-.15y+0.2y=6.6.

Then, subtract 5.55 by 6.6 to get 1.05 and 0.2y+-.15y to get 0.05 y.

Now you have 0.05y=1.05 divided 0.05 and 1.05 to get 21.

Now plug 21 into the X+Y=37 equation to get X+21=37 subtract 21 from 37 to get X=16.

So X=16 and Y=21, so the answer is 16,21.
