A ball is thrown straight up from the top of a building that is 400 ft high with an initial velocity of 64 ft/s. The height of the object can be modeled by the equation s ( t ) = -16 t2 + 64 t + 400.

In two or more complete sentences explain how to determine the time(s) the ball is higher than the building in interval notation.

Review the attached graph

By using geometry to evaluate the given integral, the value is equal to 6 units.

In order to use a geometry to evaluate a definite integral, you should identify the portion of a graph which corresponds to the given integral.

Also, you'll mark out the geometric shapes that are formed on the graph, so as to enable you calculate their areas. Finally, you'll add the areas together.

From the graph of the integral shown in the image attached below, the geometric shapes that are formed are rectangle and triangles.

For the area of rectangle, we have:

Area of rectangle = L × B

Area of rectangle = 2 × 2

Area of rectangle = 4 units.

For the area of triangle, we have:

Area of triangle = 1/2 × b × h

Area of triangle = 1/2 × 2 × 2

Area of triangle = 2 units.

Total area = 4 + 2

Total area = 6 units.

Answer:

For question 13: 25%

Step-by-step explanation:

25 out of one hundred is one fourth

25 percent of 400 is one hundred

since 4 one hundreds go into 400

take one fourth and you get one hundred

500-400=100

so 25%

I dont know what the second question is asking

Solution:

the percent markdown of the iPad is 17.86%

Given:

Original Price = $700

Final price = $575

The markdown is gotten by;

[tex]Markdown=original~price-final~price[/tex]

[tex]Markdown=700-575[/tex]

Markdown = $125

Thus, the percent markdown is gotten by;

[tex]percent~markdown=\frac{markdown}{original~price}~x~ 100[/tex]

percent markdown = [tex]\frac{125}{700}[/tex] × 100%

percent markdown =[tex]\frac{12500}{700}[/tex]

percent markdown = 17.857 %

percent markdown  ≈ 17.86%

Therefore, the percent markdown of the iPad is 17.86%

Answer:

exact form: -16/3

decimal form: -5.3

mixed number form: -5 1/3

Step-by-step explanation:

solve for x by simplifying both sides of the equation, then isolating the variable.

3/4X + 2 = 3/8X

3/4X - 3/8X = - 2

(3/4 - 3/8)X = -2

((6-3)/8)X =-2

3/8X = -2

3X = (-2)(8)

3X = -16

X = -16/3

Answer:

23/24

Step-by-step explanation:

To find the total distance of Sunday and Saturday we add 5/8 + 1/3

= 5/8 + 1/3

= 5 × 3/8 × 3 + 1 × 8/3 × 8

= 15/24 + 8/24

= 15 + 8/ 24

= 23/24

Answer:

It would be neither.

Step-by-step explanation:

It definitely is not parallel since Line 1 would run into Line 2 at (4, 1). Nor could it be perpendicular because they do run into each other but do not make a 90 degree angle.

[tex]\rightarrow24[/tex]

Answer:

Two or more independent functions (say f(x) and g(x)) can be combined to generate a new function (say g(x)) using any of the following approach.

h(x) = f(x) + g(x)h(x)=f(x)+g(x) h(x) = f(x) - g(x)h(x)=f(x)−g(x)

h(x) = \frac{f(x)}{g(x)}h(x)=

g(x)

f(x)

h(x) = f(g(x))h(x)=f(g(x))

And many more.

The approach or formula to use depends on the question.

In this case, the combined function is:

f(x) = 75+ 10xf(x)=75+10x

The savings function is given as

s(x) = 85s(x)=85

The allowance function is given as:

a(x) = 10(x - 1)a(x)=10(x−1)

The new function that combined his savings and his allowances is calculated as:

f(x) = s(x) + a(x)f(x)=s(x)+a(x)

Substitute values for s(x) and a(x)

f(x) = 85 + 10(x - 1)f(x)=85+10(x−1)

Open bracket

f(x) = 85 + 10x - 10f(x)=85+10x−10

Collect like terms

mark as brainiest

f(x) = 85 - 10+ 10xf(x)=85−10+10x

f(x) = 75+ 10xf(x)=75+10x

Answer:

B. (3x-12)+5/x

Step-by-step explanation:

Difference means - or minus

Three times a number x and 12= 3x-12

Increased= + or plus

quotient= / or divide

5 and the number x= 5/x

So the answer is,

(3x-12)+5/x

Answer:

  18050 square feet

Step-by-step explanation:

Let x represent the length of fence parallel to the creek. Then the remaining 380-x feet of fence is divided between the two ends of the pasture. The area will be the product ...

  A = (x)(1/2)(380 -x)

The graph of this is a parabola that opens downward. It has x-intercepts at x=0 and x=380. The vertex (maximum) will be on the line of symmetry, halfway between these zeros, at x = (0 +380)/2 = 190.

Then the area is ...

  A = (190 ft)(1/2)(380 -190 ft) = (190 ft²)/2 = 18,050 ft²

The maximum possible area of the pasture is 18,050 square feet.

Additional comment

Sometimes the relationships involving secants, tangents, and chords can be difficult to remember. There is basically one rule that applies to all of these geometries:

  the product of segment lengths to the circle from the point of intersection of the secants/tangents/chords is the same

A tangent can be thought of as a secant that has a length of 0 between its end points. That is, the two lengths from the point of intersection to the circle are the same.

Here is an example of this rule applied to chords:

Answer:

14.28

Step-by-step explanation:

2% of 14 is .28

.28 + 14 = 14.28

Hi!

Since the price was decreased by 2%, that means that 14 is 98% (100% - 2%) of the original price. So, we just have to figure out 98% of what number is 14.

98% can be written in decimal form as 0.98.

We can set up the following equation:

14 = 0.98x

Now, divide both sides by 0.98:

14/0.98 = 14.2857143

(2,5) is information! x = 2 and y = 5.

Use these values in the equation:

y = x + b

5 = 2 + b

Subtract 2.

3 = b

The equation of the line is y = x + 3.
