A diver is standing on a platform 24 ft above a pool. He jumps from the platform with an initial
upward velocity of 8 ft/s. Using the formula, h(t) = -16t2 + vt + s, where h is his height
above the water, t is the time, v is his starting upward velocity, and s is his starting height.
A) After how long will the diver reach its maximum height?
B) What is the maximum height the diver will reach?

Answers

Answer 1

GIVEN ↷

h(t) = -16t² + vt + s

where,

h⤿ Height ⤏0

t ⤿ time⤏?

v⤿initial velocity⤏8ft/s

s⤿initial height⤏24ft

TO FIND ↷

The maximum heightTime taken to reach the maximum height

SOLUTION ↷

we know that,

-16t² + vt + s = h(t)-16t² + 8t + 24 = 0

To factorise the equation, we'll divide the both side by 8 and multiply by -1

we get,

2t² -t -3 = 02t² +2t -3t -3 = 02t(t+1) -3(t+1) = 0(2t-3)(t +1) = 0

so,

2t - 3 = 0

2t = 3

t = 3/2

t = 1.5 seconds

hence, the diver will take 1.5 seconds to reach the maximum height

Now , to find the maximum height ,

we'll insert the value of time taken in the given equation which is ↷

h(t) = -16t² + vt + sh(1.5) = -16(1.5)² + 8 x 1.5 + 24h(1.5) = -16 x 2.25 + 12 +24h(1.5) = -36 +12 +24h(1.5) = -36 +36h(1.5) = 0h = 0/ 1.5h = 0

Hence , the maximum height the diver will reach in 1.5 seconds = 0

If 50% of some number is 75, what is 200% of that same number?

Answers

Answer:

300

Step-by-step explanation:

A percentage is a unit of proportion that represents a ratio.

For this question let the unknown number be represented by the variable x. We know that 75 is 50% of x, or half of x. This means that we can find the unknown number by doubling 75.

75*2=150

This means that x is 150. Next, we need to find 200% of 150. 200% of any number is that number times 2. So, to find the final answer we must once again double 150.

150*2=300

So, the final answer is 300.

Answer:

Step-by-step explanation:

270

50% equals to 1/2 so 1/2x=75. Times 2 on both sides you get x=135.

So 135 is x and you multiply 135 by 200%. Which get you 270.

How many points of inflection will f(x) = 3x^5 + 2x^4 – 5x 52 – 12 have?

A)3

B)2

C)5

D)4

Answers

There would be four points of inflection.

The number of inflection points of a polynomial is always one less than the equation’s leading degree.

Examples:
f(x)=2x^2 + 8 has one point of inflection
g(x)=5x^4 + 1 has three points of inflection

There are two points of inflection in the graph of f(x).

Option B is the correct answer.

What is a function?

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

To find the inflection points of a function, we need to find its second derivative and set it equal to zero.

So,

Let's start by finding the first and second derivatives of f(x).

First, we find the first derivative of f(x).

f'(x) = 15[tex]x^4[/tex] + 8x³ - 260x² - 5x²

Then,

We find the second derivative of f(x):

f''(x) = 60x³ + 24x² - 520x - 10x

Next, we set f''(x) equal to zero and solve for x.

60x³ + 24x² - 520x - 10 = 0

10 (2x² - 13x - 1) = 0

2x² - 13x - 1 = 0

Now,

Using the quadratic formula,

we find the roots of this equation:

x = (13 ± √(13² + 8))/4

x = 13 ± √177) / 4

x = (13 + √177)/4 and x = )13 - √177)/4

x = 2.22 and x = -0.23

Therefore,

There are two points of inflection in the graph of f(x).

5y=65

y=13

For a rhombus, the adjacent angles are supplementary:

74+(z-10)=180

z-10=106

z=116

74+(x+7)=180

x+7=106

x=99

Opposite angles in a paralleogram are equal

Polygon LMNPQR is shown on the coordinate grid and models the shape of a garden in a park,
Polygon LMNPQR will be dilated with the origin as the center of dilation to create polygon
L'M'N'P/Q'R'. The vertex Q' will be located at (21, 7).

Which rule best represents the dilation?

Answers

Dilation involves changing the size of the polygon

The best rule of dilation is [tex](x,y) \to \frac 72(x,y)[/tex]

How to determine the rule

The coordinates of vertices Q and Q' are given as;

Q = (6,2)

Q' = (21, 7)

The scale factor of dilation is then calculated as:

[tex]k = \frac {Q'}{Q}[/tex]

So, we have:

[tex]k = \frac {(21,7)}{(6,2)}[/tex]

Factorize

[tex]k = \frac {7/2(6,2)}{(6,2)}[/tex]

Divide

[tex]k = \frac {7}2[/tex]

So, the transformation rule is:

[tex](x,y) \to \frac 72(x,y)[/tex]

Hence, the best rule of dilation is [tex](x,y) \to \frac 72(x,y)[/tex]

If a new data point at 12 is added to the graph, The mean will increase more than the median, but both will increase.

What is Mean and Median?

Mean of a set of data is defined as the average of all the values. It gives the exact middle point of the data set.

Median of a data set is the element in the middle if the data are arranged in increasing or decreasing order.

Given a graph with the data points as,

1, 2, 2, 2, 3, 4, 4, 4, 5

Mean = (1 + 2 + 2 + 2 + 3 + 4 + 4 + 4 + 5) / 9 = 27 / 9 = 3

Median = 5th term = 3

When 12 is added, new data set has 10 data points.

1, 2, 2, 2, 3, 4, 4, 4, 5, 12

Mean = (1 + 2 + 2 + 2 + 3 + 4 + 4 + 4 + 5 + 12) / 10 = 3.9

Median = average of 5th and 6th term = (3 + 4) / 2 = 3.5

Hence the correct option is The mean will increase more than the median, but both will increase.
