Which graph represents the function f (x) = StartFraction 1 Over x EndFraction minus 1?

Answer:

both require powers

Step-by-step explanation:

Exponents refer to the power of numbers eg 3^5. Roots refer to two numbers which are the same which when multiplied result in a number. eg 3^2=9. or the square root of 9 is 3. Exponents and roots are related because they both require powers (ie..The same number multiplying itself for a number of times.

Step-by-step explanation:

The first term of the arithmetic sequence is  4x+3.

An ordered group of numbers with a shared difference between each successive term is known as an arithmetic sequence.

The formula to find the nth term of an arithmetic sequence is,

aₙ= a+(n-1)d

Where a is the 1st term and d is the common difference.

Let the first term of sequence is a and the common difference is d.

Given that,

The 5th term of the arithmetic sequence = 16x+11,

⇒ a+4d= 16x+11      (1)

And the 9th term of the arithmetic sequence = 28x+19,

⇒ a+8d= 28x+19    (2)

To find the first term of the sequence, multiply equation (1) with 2 and subtract equation (2) from it.

(2a+8d)-(a+8d) = (32x+22) - (28x+19)

a = 4x+3

The first term of the arithmetic sequence is  4x+3.

Answer:

6p - 2

Step-by-step explanation:

9p - (3p + 2) = 9p - 3p - 2 = 6p - 2

The expression that  is equivalent to 9 p minus 3 p + 2 is 6p - 2

From the question, one have 9p - 3p + 2.

So, one has to combine the like terms, which means adding or subtracting the coefficients of the same variable. For the terms with 'p', one  have 9p - 3p.

Combining the coefficients, one get 9 - 3 = 6.

So, 9p - 3p is simplifies to 6p.

So, one have 6p + 2.

The expression is said to be now simplified to 6p + 2.

This equation comes from how mush Heather sold.

Equation 2

8x+10y=200

This equation comes from how mush Kim sold.

We can use elimination method to find the value of y.

Answer:

- The actual product is less than the estimate

- The numbers differ by less than one

Step-by-step explanation:

Given

Product of 3 and two-fifths & [tex]-3\frac{7}{8}[/tex]

Required

Compare actual result with approximated result

Calculating the actual result;

3 and two-fifths means [tex]3\frac{2}{5}[/tex]

So, the Product of 3 and two-fifths & [tex]-3\frac{7}{8}[/tex] becomes

[tex]Product = 3\frac{2}{5} * -3\frac{7}{8}[/tex]

Convert fractions to improper

[tex]Product = \frac{17}{5} * -\frac{31}{8}[/tex]

Combine fractions to form one

[tex]Product = \frac{-17 * 31}{5 * 8}[/tex]

Multiply numerators and denominator

[tex]Product = \frac{-527}{40}[/tex]

Convert fraction to decimal

[tex]Product = -13.175[/tex]

The nearest half of -13.175 is -13

Hence;

[tex]Estimate = -13[/tex]

By comparison:-

- The actual product (-13.175) is less than the estimate (-13)

- The difference between both results is less than 1;

The difference is calculated as follows

Difference = |Actual Product - Estimate|

Difference = |-13.175 - (-13)|

Difference = |-13.175 +13|

Difference = |-0.175|

Difference = 0.175

the probability that exactly 1 out of 10 randomly chosen people favor the new building project is approximately 0.2791, or 27.91%.

To calculate the probability that exactly 1 out of 10 randomly chosen people favor the new building project, we can use the binomial probability formula.

The formula for calculating the probability of getting exactly k successes in n trials, each with a probability of success p, is:

P(X = k) = C(n, k) * [tex]p^k * (1 - p)^{(n - k)[/tex]

In this case, n = 10 (number of trials), k = 1 (number of successes), and p = 0.55 (probability of success).

Using the binomial coefficient formula C(n, k) = n! / (k!(n - k)!), we can calculate the probability:

P(X = 1) = C(10, 1) * (0.55)¹ * (1 - 0.55)⁽¹⁰⁻¹⁾

P(X = 1) = 10 * (0.55)¹ * (0.45)⁹

P(X = 1) ≈ 0.2791

Therefore, the probability that exactly 1 out of 10 randomly chosen people favor the new building project is approximately 0.2791, or 27.91%.

Answer:

The correct option is;

(B) 30

Step-by-step explanation:

The equations are;

x² - 2·m·x - 5·n = 0.............(1)

Solution = p, q

x² - 2·p·x - 5·q = 0..............(2)

Solution = m, n

For equation (1), we have;

x² - 2·m·x - 5·n = 0 = (x - p)·(x - q)

x² - 2·m·x - 5·n = x² -x·p - x·q + q·p = x² -x·(p + q) + q·p

2·m = p + q..............(3)

5·n = -q·p..............(4)

Given the similarity between equation (1) and (2), we have;

2·p = m + n..............(5)

5·q = -m·n..............(6)

Therefore;

m = (p + q)/2

n = -q·p/5

Substituting the value of m and n in equation (5) and (6), we have;

2·p = (p + q)/2  - q·p/5.............(7)

5·q = (p + q)/2·q·p/5.............(8)

Making q the subject of equation (7) gives;

[tex]q = \dfrac{-7.5 \cdot p}{p -2.5}[/tex]

Substituting the value of q above in equation (8) gives;

[tex]-\dfrac{75\cdot p}{2\cdot p-5}=-\dfrac{3\cdot p^{4}-30\cdot p^{3}}{4\cdot p^{2}-20\cdot p+25}[/tex]

By cross multiplying and collecting like terms we have;

6·p⁵ -75·p⁴-150·p³+1500·p²-1875·p = 0

Which gives

(p+0)(p-1.91)(p-2.5)(p+5)(p-13.1)

p = 1.91 or 2.5 or -5 or 13.1

q = 24.27 or undef or -5 or -9.27

m = 13.09 or undef or -5 or 1.95

n = -9.27 or undef or -5 or -24.29

Therefore, p + q + m + n = 1.91 + 24.27 + 13.09 + (-9.27) = 30

Answer:

58.43%

Step-by-step explanation:

The first thing we must do is calculate the probability of when both are equal, that is, take out two cookies of the same type, since we can calculate that they are not equal by means of their complement:

The probability that they are equal is:

P (plain, plain) = (12/20) (11/19)

= 132/380

P (chocolate, chocolate) = (5/20) (4/19)

 = 20/380

P (currant, currant) = (3/20) (2/19)

= 6/380

The final probability would be the sum of these:

P (equal) = 132/380 + 20/380 + 6/380

P (equal) = 158/380

P (equal) = 0.4157

The probability that they are different is the opposite of the probability that they are equal, that is, the complement. Therefore, the probability that they are different is:

P (different) = 1 - 0.4157

P (different) = 0.5843

In other words, the probability would be 58.43%

Answer:

B

Step-by-step explanation:

When you dilate by a factor of 0, this doesn't really make sense because the length of each side is multiplied by 0, and the shape basically doesn't exist anymore. When you multiply by a scale factor of 1, the figure does not change in size at all. When you dilate by a scale factor of 5, each side length gets 5 times larger, meaning that this is not a reduction. Hope this helps!

Answer:

y = 7x - 4

Step-by-step explanation:

To solve the equation of this line ( in point - slope form ) we would have to first identify the slope. If we are given the points ( 0, - 4 ) and ( 1, 3 ) then through the change in y / change in x, we can calculate the value of this slope. Take a look at the steps below;

[tex]( 0, - 4 ), ( 1, 3 )\\\\Slope = y2 - y1 / x2 - x1,\\\\Slope = - 4 - 3 / 0 - 1,\\Slope = - 7 / - 1\\Slope = 7 / 1\\\\Slope = 7[/tex]

Now that we have the slope of this line, we have assume part of the equation of this line ( that passes through the points ( 0, - 4 ) and ( 1, 3 ) );

[tex]y = mx + b -\\m = slope, b = y - intercept[/tex]

Plug in the value of slope for " m " in y = mx + b, and determine the y - intercept by plugging in x as 0 and y as - 4, given the point ( 0, - 4 );

[tex]- 4 = 7 * ( 0 ) + b,\\- 4 = 0 + b,\\b = - 4[/tex]

From this information, we can say that the equation of this line is y = 7x - 4;

Solution, y = 7x - 4

Answer:

Carmen needs more than 5 hours to meet her goal.

Step-by-step explanation:

65t + 25 > 350

t > 25

Carmen could reach 350 total miles at 5 hours if she drives at a constant rate of 65 miles per hour. To reach over 350 miles, Carmen will need to drive for more than 5 hours.

So, Carmen needs more than 5 hours to meet her goal.
