Answer:

9 is correct answer

Step-by-step explanation:

[tex] {x}^{2} - 6x - 27 \\ = {x}^{2} - 9x + 3x - 27 \\ = x(x - 9) + 3(x - 9) \\ = (x + 3)(x - 9)[/tex]

x=9

Answer:

(x - 9)(x + 3)

Step-by-step explanation:

Given

x² - 6x - 27

Consider the factors of the constant term (- 27) which sum to give the coefficient of the x- term (- 6)

The factors are - 9 and + 3, since

- 9 × 3 = - 27 and - 9 + 3 = - 6, thus

x² - 6x - 27 = (x - 9)(x + 3)

Answer:

2/7 or 2 over 7

Step-by-step explanation:

4/14 can be simplified. We know this because both 4 and 14 can be divided by 2. 4 divided by 2 = 2 and 1 divided by 2 = 7, thus the answer is 2 over 7.

Answer:

4483.1

Step-by-step explanation:

Helix shape of the metal fitting parameterized :

C(t) = (cos(t), sin(t), t )

This shows that:  x = cos(t), y = sin(t), z = t

density of the metal can be represented as

f (x(t), y(t), z(t) = 2z = 2t

To calculate the mass of the fitting an integral is generated below ( attached below is remaining part of the solution )

Steps to solve:

Answer:

[tex]Second = \$213876[/tex]

Step-by-step explanation:

Given

Highest Winning = $262,743

Second Highest Winning = 81.4012% of the first

Required

Determine the value of the second highest winning

Recall that

[tex]Second\ Highest\ Winning = 81.4012\%\ of\ the\ first[/tex]

Substitute $262,743 for the first highest winning

[tex]Second = 81.4012\%\ of\ \$262,743[/tex]

[tex]Second = 81.4012\%\ * \$262,743[/tex]

[tex]Second = \$213875.954916[/tex]

Approximate

[tex]Second = \$213876[/tex]

Hence, the second highest winning is approximately $213876

Answer:

[tex]S(r)=4\pi r^2[/tex].

Step-by-step explanation:

It is given that, the surface area S of a single-celled organism may be found by multiplying 4π times the square of the radius r of the cell.  

We need to express S as a function of r.

Let r be the radius of the cell and S(r) be the surface area of single-celled organism when radius is r.

According to the question,

[tex]S(r)=4\pi \times r^2[/tex]

[tex]S(r)=4\pi r^2[/tex]

Therefore, the required function is [tex]S(r)=4\pi r^2[/tex].

Answer:

-4

Step-by-step explanation:

So we have the function:

[tex]h(x)=-3x-4[/tex]

To find h(0), substitute 0 for x. Thus:

[tex]h(0)=-3(0)-4[/tex]

Multiply:

[tex]h(0)=0-4[/tex]

Subtract:

[tex]h(0)=-4[/tex]

And we're done!

Answer:

A sinusoidal model would be used

The kind of function that have consistency in the periodic rate of change is the Average rate of changes

Step-by-step explanation:

The type of model that would be used is sinusoidal model and this is because there is periodic change in the values given ( i.e the rate of changes given )

For percentage rate of changes :

starting from 0.9% there is an increase to 1.3% then a decrease to 1.1% and a further decrease to 1% before an increase to 1.3% and another decrease to 1%

For Average rate of changes:

starting from 2.9 there is a decrease to 2.4, then an increase to 3.7 and another decrease to 3.1 followed by an increase to 3.6 and a decrease back to 3.2

This relation ( sinusoidal model ) is best suited for a linear model because there is a periodic rate of change in the functions

The kind of function that have consistency in the period rate of change is the Average rate of changes

Answer:

[tex]Y = 441[/tex]

Step-by-step explanation:

Given

M = 27 when Y = 16 and X = 9

Required

Find Y when M = 7 and X = 2

We start by getting the algebraic representation of the given statement

[tex]X^2 \alpha \frac{1}{\sqrt Y} \alpha M[/tex]

Convert the variation to an equation; we have

[tex]X^2 = \frac{KM}{\sqrt Y}[/tex]

Where K is the constant of variation;

When M = 27; Y = 16; X = 9, the expression becomes

[tex]9^2 = \frac{K * 27}{\sqrt{16}}[/tex]

This gives

[tex]81 = \frac{k * 27}{4}[/tex]

Make K the subject of formula

[tex]K = \frac{81* 4}{27}[/tex]

[tex]K = \frac{324}{27}[/tex]

[tex]K = 12[/tex]

Solving for Y when M = 7 and X = 2

Recall that [tex]X^2 = \frac{KM}{\sqrt Y}[/tex]

Substitute values for K, M and X

[tex]2^2 = \frac{12 * 7}{\sqrt{Y}}[/tex]

[tex]4 = \frac{84}{\sqrt{Y}}[/tex]

Take square of both sides

[tex]4^2 = (\frac{84}{\sqrt{Y}})^2[/tex]

[tex]16 = \frac{7056}{Y}[/tex]

Make  Y the subject of formula

[tex]Y = \frac{7056}{16}[/tex]

[tex]Y = 441[/tex]

Answer:

B. about 5 days.

Step-by-step explanation:

If you average;

400 miles per day

1990 miles trip would take?

Cross multiplying gives;

[tex]\frac{1990 * 1}{400}[/tex] = 4.975 days

Rounding off the answer to nearest day gives 5 days.

Hence the 1990 miles journey should take about 5 days.

A trip of 1990 miles would take around 5 days if you averaged 400 miles each day. Option B is correct.

It is described as the single number that embodies the mean value for the specified collection of data or the closed value for each item in the specified set of data.

It is given that, you averaged 400 miles per day,

We have to find the days would a trip of 1990 miles takes.

The number of days is obtained by taking the ratio of the total distance we have to travel to the distance traveled by the person in one day.

Suppose the number of days needed to complete the trip will be x,

x=Total distance/distance in one day

x=1990 / 400

x= 4.975 days

x≈5 days

If you averaged 400 miles each day, a trip of 1990 miles would take around 5 days.

Thus, option B is correct.

Answer: 0.03538944

Step-by-step explanation:

Given, The accuracy of missile = 96%

i.e. The probability that it will hit the shot = 0.96

Probability of missing the shot = 1-0.96= 0.04

Now, each missile is independent of other.

Therefore, the probability only the second one misses = (probability that first will hit the shot) x (probability that second one misses ) x (probability that third will hit the shot)x (probability that fourth will hit the shot)

Thus, the probability only the second one misses is [tex](0.96)(0.04)(0.96)(0.96)=0.03538944[/tex]

Hence, the required probability = 0.03538944

Answer: There are 100 boys at the concert

Step-by-step explanation:

If the the ratio of  boys to girls is 2:5 and and there are 250 girls  then a number was multiplied by 5 to get 250  and that number needs to be multiply by 2  to find the number of boys.

So to find that number we will divide 250 by 5.

250/ 5 = 50  

50 * 2 = 100

Answer: -4/10

Step-by-step explanation:

Since we are finding the slope, we have to do the rise over run strategy. In this case, rise (y) are the numbers  -3 and 1 and the run (x) is the numbers -6 and 4. After that, we subtract them. So, -3 - 1 and -6 - 4. We get -4 over -10 (or - 4/10) which is your slope.

Answer: 4 2/3

Step-by-step explanation:
