The function f(x) = –2x2 + 32 represents the height of an object, f(x), after x seconds. How many seconds does it take for the object to hit the ground?

Answers

Given:

The height of an object, f(x), after x seconds is

[tex]f(x)=-2x^2+32[/tex]

To find:

The time taken be object to hit the ground.

Solution:

We have,

[tex]f(x)=-2x^2+32[/tex]

The object will hit the ground if the height is 0, i.e., f(x)=0.

[tex]0=-2x^2+32[/tex]

[tex]2x^2=32[/tex]

Divide both sides by 2.

[tex]x^2=\dfrac{32}{2}[/tex]

[tex]x^2=16[/tex]

Taking square root on both sides.

[tex]x=\pm 4[/tex]

Time cannot be negative. So, x=4.

Therefore, the object will hit the ground after 4 seconds.

Find the percent of change:
From 64 feet to 48 feet

Answers

Answer:16

Step-by-step explanation:

Using this tool you can find the percent Decrease for any value. So, we think you reached us looking for answers to questions like:

1) What is the percentage Decrease from 64 to 48? 2) What is the absolute Decrease from 64 to 48. Or may be: What is the percent change from 64 to 48?

See the solution to these problems just after below.

How to calculate percent change - Step by Step

Percent increase or decrease measures percent changes between two values. Use this calculator when comparing an old value to a new value.

The Percent Calculator (Change) uses this formula:

% change = New Value - Old Value|Old Value|× 100%

Where |Old Value| represents the absolute value of the reference (this is made in order to work well with both positive and negative values of Old Value and New Value. Note that percent change and relative change mean the same thing. It can be a percent increase or a percent decrease depending on the new and the old values. If the new value is greater than the old value, the result will be positive and we will have a increase. On the other hand, if the new value is smaller than old value, the result will be negative and we will have a we have a decrease. The old value, as a reference, may be: a theoretical, the actual, the correct, an accepted, an optimal, the starting, and so on. See more about percent percent change here.

Here are the solutions to the questions stated above:

1) What is the percentage decrease from 64 to 48?

Use the above formula to find the percent change. So, replacing the given values, we have

Percent change = 48 - 6464 x 100 = -25 % (decrease)

Where: 64 is the old value and 48 is the new value. In this case we have a % of decrease because the new value is smaller than the old value.

2) What is the absolute Decrease from 64 to 48?

This problem is not about percent or relative change, but about absolute change. Its solution is very simple:

Absolute change, or

change = new value - old value

= 48 - 64 = -16 (decrease)

Answer: -25%

Step-by-step explanation:A change from 64 to 48 represents a negative change (decrease) of -25%

Use the formula found below on this webpage to find the percent change by replacing the given values:

Percent change = New - Old

|Old|

x 100%

Percent change = 48 - 64

|64|

x 100 = -16

64

x 100 = -25 % (decrease)

Where: 64 is the old value and 48 is the new value. In this case we have a negative change (decrease) of -25 percent because the new value is smaller than the old value.

What are some basic properties of exponentiation?

If we have [tex]a^b[/tex] then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).

Exponentiation(the process of raising some number to some power) have some basic rules as:

[tex]a^{-b} = \dfrac{1}{a^b}\\\\a^0 = 1 (a \neq 0)\\\\a^1 = a\\\\(a^b)^c = a^{b \times c}\\\\ a^b \times a^c = a^{b+c} \\\\^n\sqrt{a} = a^{1/n} \\\\(ab)^c = a^c \times b^c\\\\a^b = a^b \implies b= c \: \text{ (if a, b and c are real numbers and } a \neq 1 \: and \: a \neq -1 )[/tex]

How can we rewrite a constant as a coefficient?

Suppose there is a constant 'c'.

We can write it as:

[tex]c = c \times 1 = c \times x^0[/tex]

where 'x' is the variable in consideration. Here even when x = 0, we would assume that for all real numbers 'x', its power raised to 0 makes it evaluate to 1.

For this case, we can rewrite both the terms as:

[tex]9x = 9x\times 1 = 9x \times x^0[/tex][tex]45 = 45 \times 1 = 45 \times x^0[/tex]

Thus, the maximum of x that can come out common out of these two terms is [tex]x^0[/tex] (its degree, or power, or exponent is 0)

Thus, the largest degree of x that can be factored out of all terms 9x and 45​ is 0

The ratio of money in Terry's bank account to Faye's bank account was 3:7. Terry then put £220 in his account and Faye withdrew £300 from her account. They now had the same amount in their accounts. How much did Terry initially have?

Answers

Answer:

Terry initially had £390

Step-by-step explanation:

The ratio of the original amount is 3:7

Let the original amount Terry has be t and the original amount Faye has be f

3/7 = t/f

or simply 3f = 7t ••••••(i)

Terry putting 220 means he now has

t + 220

Faye withdrew 300

He now has f-300

These values are equal

t + 220 = f-300

f = t+220+300

f = t + 520 ••••••(ii)

Put ii into i

3(t + 520) = 7t

3t + 1560 = 7t

7t-3t = 1560

4t = 1560

t = 1560/4

t = 390

A farmer is going to divide her 40 acre farm between two crops. Seed for crop A costs $15 per acre. Seed for crop B costs $30 per acre. The farmer can spend at most $900 on seed. If crop B brings in a profit of $50 per acre, and crop A brings in a profit of $110 per acre, how many acres of each crop should the farmer plant to maximize her profit? acres of crop A acres of crop B

Answers

Answer:

The answer is below

Step-by-step explanation:

Let x represent the number of acre on which crop A is farmed and B represent the number of acre crop B is farmed.

Therefore:

Since there is a total of 40 acre farm, hence:

x + y = 40        (1)

The farmer can spend at most $900 on seed, crop A seed cost $15 and crop B seed cost $50, hence:

15x + 50y ≤ 900   (2)

Her profit is given as:

Profit = 50x + 110y

From the geogebra plot, the point that maximizes the profit is at (60, 0)

Therefore the maximum profit = 50(60) + 110(0) = $3000

Find the 55th term of the arithmetic sequence 2, -18,-38

Answers

Answer:

-1078

Step-by-step explanation:

n=0 is the first term in the sequence.

Every next term is 20 less then the previous term.

In Mathematics you can write this as follows:

f(n) = f(0) - (n-1)*20

f(n) = f(0) - {(n-1)*20}

f(n) = f(0) - {(20n) -20}

Attention: Please note that -1 * -20 = +20

f(n) = f(0) - 20n + 20

Check yourself, find f(2):

f(0) = 2

f(2) = 2 - 20*2 + 20

f(2) = 2 - 40 + 20

f(2) = 2 - 20

f(2) = -18

Check yourself once more, find f(3):

f(0) = 2

f(3) = 2 - 20*3 + 20

f(3) = 2 - 60 + 20

f(3) = 2 - 40

f(3) = -38

Now just find f(55):

f(55) = 2

f(55) = 2 - 20*55 + 20

f(55) = 2 - 1100 + 20

f(55) = 2 - 1080

f(55) = -1078

The average depth of the Artic Ocean is 3.953 x 10^5 feet while the average depth of the Atlantic Ocean is 1.2851 x 10^4 feet. Approximately how many times more deep is the Atlantic Ocean that the Artic Ocean?

Answers

Answer:

Hence the artic depth is approximately 31 times deeper than atlantic

Step-by-step explanation:

Given the following;

Average depth of the Artic Ocean = 3.953 x 10^5 feet

Average depth of the Atlantic Ocean = 1.2851 x 10^4 feet.

Taking the ratio of both depth;

Ratio = Depth of Artic/Depth of Atlantic

Ratio =  3.953 x 10^5/1.2851 x 10^4

Ratio =  3.076 * 10^1

Ratio = 30.76

Depth of artic/depth of atlantic = 30.76

Depth of artic = 30.76 * depth of atlantic

Hence the artic depth is approximately 31 times deeper than atlantic

Add 7 to each side

5x - 7+7 = 3+7

5x = 10

Divide each side by 5

5x/5 = 10/5

x = 2

Answer:

x = 2

Step-by-step explanation:

5x-7=3

Move the 7 from the left side. So you'll add it to both sides

5x-7(+7)=3(+7)

Making your formula

5x=10

Then divide 5x on both sides

Since 5x divided by itself is one it's just x

10 divided by 5 is 2

So the answer is x = 2

Step 1: Define systems

-5x + 2y = 9

y = 7x

Step 2: Solve for x

Substitution

Substitute in y:                              -5x + 2(7x) = 9Multiply:                                         -5x + 14x = 9Combine like terms:                      9x = 9Isolate x:                                         x = 1

Step 3: Solve for y

Define original equation:                    y = 7xSubstitute in x:                                     y = 7(1)Multiply:                                                y = 7

Answer: x = 1 and y = 7

Step-by-step explanation:

first you substitude y for 7x

-5x + 2(7x) = 9

then you distribute

-5x + 14x = 9

then you combine like terms

9x = 9

then you divide both sides by 9

x = 1

then you subsitute the x value in the other equations

y = 7(1)

meaning y = 7
