Step-by-step explanation:

A polynomial has roots at the points where the curve cuts the x axis.

This can also be said as values of x for which the polynomial is 0

Given that when x =a is root means, we have x-a is the factor.

Based on the above, we find when 3/4, -7/8, -3/8 and -1/9 are roots

factors are x-3/4, x+7/8, x+3/8, x+1/9

Hence answer is

B) (x + 3/8)

The other options do not match with the factors only option Bmatches.

Answer: The factor of the polynomial is [tex](x+\frac{3}{8})[/tex]

Step-by-step explanation:

We are given:

4 roots of the polynomial

Root 1: [tex]\frac{3}{4}[/tex]

The factor for this root becomes: [tex](x-\frac{3}{4})[/tex]

Root 2: [tex]\frac{-7}{8}[/tex]

The factor for this root becomes: [tex](x+\frac{7}{8})[/tex]

Root 3: [tex]\frac{-3}{8}[/tex]

The factor for this root becomes: [tex](x+\frac{3}{8})[/tex]

Root 4: [tex]\frac{-1}{9}[/tex]

The factor for this root becomes: [tex](x+\frac{1}{9})[/tex]

Hence, the factor of the polynomial is [tex](x+\frac{3}{8})[/tex]

_____

98.20 - 0.62 = 97.58 . . . 1 standard deviation below the mean

98.20 + 0.62 = 98.82 . . . 1 standard deviation above the mean

Approximately 68% of healthy adults have body temperatures between 97.58°F and 98.82°F, as per the empirical rule which states that about 68% of data falls within one standard deviation of the mean in a bell-shaped distribution.

Using the empirical rule (also known as the 68-95-99.7 rule), we can determine the approximate percentage of healthy adults with body temperatures between 97.58°F and 98.82°F. The empirical rule states that for a bell-shaped distribution:

Approximately 68% of the data falls within one standard deviation of the mean.

Approximately 95% falls within two standard deviations.

Approximately 99.7% falls within three standard deviations.

Given that the mean body temperature is 98.20°F and the standard deviation is 0.62°F:

One standard deviation from the mean includes temperatures from 98.20°F - 0.62°F to 98.20°F + 0.62°F, which is 97.58°F to 98.82°F.

Therefore, approximately 68% of healthy adults have body temperatures between 97.58°F and 98.82°F according to the empirical rule.

Final answer:

The inequality models a situation where you have at least 45 dollars and you are adding $10 for each additional unit.

Explanation:

The inequality 5 + 10w ≥ 45 can be modeled by a situation where you have at least 45 dollars and you are adding $10 for each additional unit. Let's solve it step by step:

1. Subtract 5 from both sides of the inequality: 10w ≥ 40.

2. Divide both sides by 10: w ≥ 4.

The solution to the inequality is w ≥ 4. This means that the situation being modeled is where you have at least 4 units of something.

Answer: Please, see the attached file.

Thanks.

Solution:

We can graph using the intercepts:

(1) y-intercept, when x=0

y=4x-3→y=4(0)-3→y=0-3→y=-3

Point=(x,y)=(0,-3)

(2) x-intercept, when y=0

y=4x-3→0=4x-3

Solving for x: Adding 3 both sides of the equation:

0+3=4x-3+3

3=4x

Dividing both sides of the equation by 4:

3/4=4x/4

3/4=x

x=3/4=0.75

Point=(x,y)=(3/4,0)=(0.75,0)

With these pair of points (0, -3) and (0.75,0) we can draw the right line

The function is linear, so its rate of change is the same everywhere. That rate of change is the coefficient of the variable x, so is $2.90. Since the units of x are feet, and the units of P(x) are dollars, the rate of change $2.90 must be ...

... A. $2.90 per square foot

The average rate of change for the given cost function over the interval [2,000, 2,500] is calculated using the slope formula, resulting in an average rate of $2.90 per square foot, corresponding to option A.

The question asks to find the average rate of change of the cost function P(x) = $2.90x + $103.00, where x represents the square footage of the carpet, over the interval of [2,000, 2,500 square feet]. To calculate the average rate of change, we use the formula of the slope between two points on the function:

(P(x_2) - P(x_1)) / (x_2 - x_1).

So for the interval [2,000, 2,500], we have:

(P(2500) - P(2000)) / (2500 - 2000) = (($2.90 \times 2500 + $103.00) - ($2.90 \times 2000 + $103.00)) / (2500 - 2000).

This simplifies to:

($7250 + $103 - $5800 - $103) / 500 = $1450 / 500 = $2.90 per square foot.

Therefore, the average rate of change over the interval [2,000, 2,500] is $2.90 per square foot, which corresponds to option A.

Answer:  [tex]7:8:9 = 10.5:12:13.5[/tex]

Step-by-step explanation:

Suppose,  [tex]7:8:9= x:12:y[/tex]

Now according to the ratio, the equations will be........

[tex]\frac{7}{8}=\frac{x}{12}\\ \\ 8x=7*12=84\\ \\ x=\frac{84}{8}=10.5[/tex]

and

[tex]\frac{8}{9}=\frac{12}{y}\\ \\ 8y=9*12=108\\ \\ y=\frac{108}{8}=13.5[/tex]

So, the ratio will be  [tex]7:8:9 = 10.5:12:13.5[/tex]

The ratio is [tex]\boxed{7:8:9 = 10.5:12:13.5}[/tex].

Further Explanation:

Given:

The ratio is [tex]7:8:9[/tex] and is equal to [tex]{\text{\_\_\_}}:{\text{12}}:{\text{\_\_\_}}[/tex].

Calculation:

Consider the number in the first blank as [tex]x[/tex].

Consider the number in the second blank as [tex]y[/tex].

Therefore, the ratio is [tex]7:8:9[/tex] and is equal to [tex]{{x}}:{\text{12}}:{{y}}[/tex]

From the given equation the ratio of [tex]7:8[/tex] is equal to the ratio of [tex]x:12[/tex].

Now equate [tex]\dfrac{7}{8}[/tex] and [tex]\dfrac{x}{12}[/tex] to obtain the value of [tex]x[/tex].

[tex]\begin{aligned}\frac{7}{8} &= \frac{x}{{12}} \\ \frac{7}{8} \times 12 &= x \\ \frac{{21}}{2} &= x \\ 10.5 &= x \\ \end{aligned}[/tex]

Therefore, the value of [tex]x[/tex] is [tex]10.5[/tex].

From the given equation the ratio of [tex]8:9[/tex] is equal to the ratio of [tex]12:y[/tex].

Now equate [tex]\dfrac{8}{9}[/tex] and [tex]\dfrac{12}{{y}}[/tex] to obtain the value of [tex]y[/tex].

[tex]\begin{aligned}\frac{8}{9} &= \frac{{12}}{y} \\ \frac{9}{8} &= \frac{y}{{12}} \\ \frac{9}{8} \times 12 &= y \\ \frac{{27}}{2} &= y \\ 13.5&= y \\\end{aligned}[/tex]

Therefore, the value of [tex]y[/tex] is [tex]13.5[/tex].

Hence, the ratio is [tex]\boxed{7:8:9 = 10.5:12:13.5}[/tex].

Answer:

  3 8/33

Step-by-step explanation:

You want the mixed-number equivalent of the repeating decimal 3.2424....

A repeating decimal fraction that starts at the decimal point can be converted to a ratio of integers by expressing the repeating digits over the same number of 9s.

Here, the two repeating digits "24" mean the fraction equivalent is ...

  0.2424... = 24/99 = 8/33

The mixed number equivalent of 3.2424... is 3 8/33.

__

Additional comment

If the repeating portion does not start at the decimal point, you can use the following technique to do the conversion.

Effectively, this multiplies and divides the number by ((10^n) -1)/((10^n) -1). In the case here, that would be multiplication by 1 in the form 99/99.

  3.242424... × 99/99 = 321/99 = 3 8/33

The "321" will be manifested on a calculator as 320.99999.... If you multiply by (100 -1) with pencil and paper, you can see that you get ...

  324.2424... - 3.2424... = 321 . . . . . . repeating digits cancel

If the repeat starts somewhere else, you can still use the "fraction with equal number of 9s" technique, but with a multiplier:

  3.6242424... = 3.6 + 0.0242424 ... = 3.6 + (1/10)(24/99)

  = 36/10 + 8/330 = 3 103/165

<95141404393>

3.242424... as a mixed number is [tex]\(3 \frac{8}{33}\)[/tex].

To express the repeating decimal 3.242424... as a mixed number, we can first write it as an infinite geometric series.

Let x = 3.242424.... Then, multiplying x by 100 gives 100x = 324.242424...

Now, subtract x from 100x:

100x - x = 324.242424... - 3.242424...

99x = 321

Now, solve for x:

[tex]\[ x = \frac{321}{99} \][/tex]

Now, express the fraction [tex]\(\frac{321}{99}\)[/tex]as a mixed number.

[tex]\[ \frac{321}{99} = 3 \frac{24}{99} \]\\Now, simplify the fraction:\[ \frac{24}{99} = \frac{8}{33} \][/tex]

So, 3.242424... as a mixed number is [tex]\(3 \frac{8}{33}\)[/tex].

4 years=48 months

A new car costs 25,000, but she will get 13,000 for her used car as long as she takes good car of it. If she takes good care of her used car and gets 13,000 for it, she will only need to save 12,000 total. We can divide 12,000 by 48 to find out how much Courtney should save minimum each month to afford her new car. 12,000/48=250

You can check to see if this is correct by multiplying 48*250=12,000. Paying 250 for each month of the 48 months will equal the $12,000 that Courtney needs.

Courtney needs to save at least $250 per month to afford her new car in 4 years.

I hope this helps :)

Courtney should save at least $250 per month for the next 4 years to be able to pay cash for the new car after considering the amount she'll receive from selling her used car.

Courtney needs to save money to buy a new car in 4 years. The estimated cost of the new car is $25,000, and she expects to get $13,000 for her used car. To find out the least amount she should save each month, we will subtract the expected amount from the sale of her used car from the cost of the new car, and then divide by the number of months in 4 years (48 months).

The calculation is as follows:

Total amount needed = Cost of New Car - Sale of Used Car
= $25,000 - $13,000
= $12,000

Monthly savings required = Total amount needed \/ Number of months
= $12,000 \/ 48
= $250

Therefore, Courtney should save at least $250 per month to pay cash for her new car in 4 years.

Answer:

  about 35

Step-by-step explanation:

This question is asking for an estimate, which means you round the number(s) to something convenient to perform the calculation.

Here, 47% is conveniently rounded to 50% = 50/100 = 1/2. Then 1/2 of 70 is ...

  1/2·70 = 70/2 = 35

A reasonable estimate of 47% of 70 is 35.

___

As you get more sophisticated in your estimating, you can also estimate the error. This estimate is about 3% (of 70) high, so is high by 3/100·70 = 2.1. That means the real answer is 35 - 2.1 = 32.9.

You could also estimate the error as 3% of 100 = 3/100·100 = 3, so you could say the actual value is between 35-3 = 32 and 35. Since 100 is larger than 70, you know that 3% of 100 is larger than 3% of 70, so this is an over-estimate of the error.

800 - 900 = -100. = 100/800=.125 x 100 = 12.5% increase.

The range is the output value

f(-2) = 2(-2)+7 =3

f(3)= 2(3)+7 = 13

f(8) = 2(8)+7 = 23

The range is 3,13,23

There are the following numbers for which that holds:

{-4, -2, -1, 0, 1, 2, 4}

See table below. For larger than 5 it can be proved that the number of digits will never be the same.

(sorry i dont have an explenation i litterally guessed it when I entered it in the RSM portal.)

Step-by-step explanation:

To complete the square, you can add (and subtract) the square of half the x coefficient.

... y = x² -10x + 30

... y = (x² -10x +25) + (30 -25)

... y = (x -5)² +5

C

given x² + 16x = 41

to complete the square on this equation

since the coefficient of the x² term is 1

add (half the coefficient of the x-term )² to both sides

x² + 2(8)x + 64 = 41+ 64

(x + 8 )² = 105 → C

Answer:

Option C is correct

Step-by-step explanation:

Given the equation

[tex]x^2+16x=41[/tex]

we have to find the equation results from completing the square.

For completing the square method, since the coefficient of [tex]x^2[/tex] is 1 therefore we have to divide the coefficient of x by 2 and then squaring of that value adding on both sides of equation, we get

Here coefficient of x is 16 therefore square of half the number adding both sides

[tex]x^2+16x+64=41+64[/tex]

[tex]x^2+8x+8x+64=105[/tex]

[tex]x(x+8)+8(x+8)=105[/tex]

[tex](x+8)(x+8)=105[/tex]

[tex](x+8)^2=105[/tex]

Option C is correct

A function assigns the value of each element of one set to the other specific element of another set. The value of f(3) is 100.

A function assigns the value of each element of one set to the other specific element of another set.

As the recursive function is given to us, f(n + 1) = –10f(n), also the value of f(1)=1 , therefore, the value of f(2) can be written as,

[tex]f(n + 1) = -10f(n)\\\\f(1 + 1) = -10f(1)\\\\f(2)= -10 \times 1\\\\f(2)=-10[/tex]

Now, the value of f(3) can be written as,

[tex]f(n + 1) = -10f(n)\\\\f(2 + 1) = -10f(2)\\\\f(3)= -10 \times -10\\\\f(3)= 100[/tex]

Hence, the value of f(3) is 100.
