Complete question

The line segment is reflected about the y-axis to form C'D'. Which statement describes C'D'?

C'D' is perpendicular to CD.

C'D' is half the length of CD.

C'D' is greater than twice the length of CD.

C'D' and CD are equal in length.

the formula for the polynomial is:

p(x) = (-3/10)*(x - 2)^2*(x + 5)

Here we have a polynomial with the following roots:

So, if we define A as the leading coefficient, we can write the polynomial as:

p(x) = A*(x - 2)^2*(x + 5)

We know that the y-intercept is -6, so evaluating in x = 0 we should get:

p(0) = -6 = A*(0 - 2)^2*(0 + 5) = A*4*5 = A*20

         -6/20 = A = -3/10

Then the formula for the polynomial is:

p(x) = (-3/10)*(x - 2)^2*(x + 5).

The margin of error for a 95% confidence interval assuming the previous study enrolled 600 individuals is C . E = ± 4.00

Based on the information, the following can be deduced:

n = 600

mean = 490.

standard deviation = 50.

At 95% confidence interval, z will be:

= 1 - 95%

= 0.05

Using the distribution table, the value will be Z(0.05/2) = Z value of 0.025 = 1.96

Therefore, the margin of error for a 95% confidence interval assuming the previous study enrolled 600 individuals will be:

The transformation that occurs from f(x) to g(x) is the graph of f(x) is shifted to the left to create g(x).

The equations of the functions are given as

f(x) = |x|

g(x) = |x + 3|

The above implies that

g(x) = f(x + 3)

When a function is shifted to the left by h units, it is represented as

g(x) = f(x + h)

This means that

h = 3

So, the transformation that occurs from f(x) to g(x) is the graph of f(x) is shifted to the left to create g(x).

Hence, the required transformation that occurs from f(x) to g(x) is the graph of f(x) is shifted to the left to create g(x).

[tex]\sqrt{20} \text{ or } 2\sqrt{5}[/tex]

Step-by-step explanation:

So in this question we want to use the Pythagorean Theorem which essentially gives us a relationship between the sides of a triangle and is as follows: [tex]a^2+b^2=c^2[/tex]

In this formula the "a" and "b" represent the base and the height and "c" represents the hypotenuse of the triangle

The order in which you assign "a" and "b" do not matter, so let's just say that: [tex]a=4\ \text{and}\ c=6[/tex]

Although it is important that you assign the hypotenuse to "c".

So plugging in known values we have the equation:

[tex]4^2 +b^2=6^2[/tex]

Square the values

[tex]16+b^2=36[/tex]

Subtract1 16 from both sides

[tex]b^2=20[/tex]

take the square root of both sides

[tex]b=\sqrt{20}[/tex]

This "b" represents our other side, which we did not initially know, so this is our answer :)

You can simplify this further by separating the radical into: [tex]\sqrt{20} = \sqrt{4} * \sqrt{5} = 2\sqrt{5}[/tex]

so, first $300 must be paid without any ifs and whens.

for the rest of the amount the insurance will cover 70%.

the bills total to

700 + 930 = $1630

he must pay $300 of that directly.

that leaves 1630 - 300 = $1330 for the 70/30 split between insurance and patient.

the patient must pay 30% of these $1330.

100% = 1330

1% = 100%/100 = 1330/100 = $13.30

30% = 1% × 30 = 13.30 × 30 = $399

so, the patient pays

300 + 399 = $699

of the $1630 bill.

The maximum possible perimeter of the triangle 25cm.

What is perimeter of a triangle?

The length of all a triangle's sides added together yields the perimeter of a triangle.

How to calculate the perimeter of a triangle?

Add the lengths of the triangle's sides to determine its perimeter. For instance, the perimeter of a triangle with sides a, b, and c is P = a + b + c.

Given the lengths of sides of triangle are 7cm, 8cm, and 10cm.

The perimeter of the triangle is 7 + 8 + 10 = 25cm

Therefore, the maximum possible perimeter of the triangle 25cm.

The value of x in the logarithm equation log₄(9x²) = log₂(5x - 8) is x = 4

The equation is given as

log₄(9x²) = log₂(5x - 8)

Apply the change of base law of logarithm

So, we have

log(9x²)/log(4) = log₂(5x - 8)

Express 4 s 2^2 and 9 as 3^2

So, we have

log(3x)²/log(2²) = log₂(5x - 8)

Apply the power law of logarithm

So, we have

2log(3x)/2log(2) = log₂(5x - 8)

Evaluate the quotient

So, we have

log(3x)/log(2) = log₂(5x - 8)

Apply the change of base law of logarithm

So, we have

log₂(3x) = log₂(5x - 8)

Cancel out the common base

So, we have

3x = 5x - 8

Collect the like terms

So, we have

3x - 5x = - 8

Evaluate the like terms

So, we have

-2x = - 8

Divide both sides by -2

So, we have

x = 4

Hence, the value of x in the logarithm equation log₄(9x²) = log₂(5x - 8) is x = 4

16 3/4 days in total.

that are (16×4 + 3)/4 = 67/4 days.

he has taken

1 3/4 = (1×4 + 3)/4 = 7/4 days

4 2/3 = (4×3 + 2)/3 = 14/3 days

2 1/6 = (2×6 + 1) = 13/6 days

to be able to add abd subtract them directly, we need to bring all fractions to the same denominator.

we have 3, 4, 6 : the smallest common multiple is 12 (can be divided without remainder by 3, 4 and 6).

we need to multiply each fraction by a fitting n/n factor to bring the denominators to 12 and keep the overall value of the fraction unchanged.

67/4 = 67/4 × 3/3 = 201/12

7/4 = 7/4 × 3/3 = 21/12

14/3 = 14/3 × 4/4 = 56/12

13/6 = 13/6 × 2/2 = 26/12

the remaining vacation time is

201/12 - 21/12 - 56/12 - 26/12 = 98/12 = 49/6

The correct answer is D. the x- intercept of the given graph is (-1.75,0) and y - intercept is (0,3)

The x-intercept is the location where a line's graph crosses the x-axis.

The y-intercept is the location where a line's graph crosses the y-axis.

The shapes of these points are (x,0) and (0,y), respectively.

Utilize the fact that all x-intercepts have a y-value of zero and all y-intercepts have an x-value of zero to get the x- and y-intercepts algebraically.

The number of toppings where the cost of each pizza would be equal is 5.

The first step is to formulate an equation that represents the cost of each type of pizza.

Cost of pizza A = $10 + $1.50t

Cost of pizza B = $12.50 + t

When the cost of both pizzas are equal, the above equations would be equal to each other.

$10 + $1.50t = $12.50 + t

To determine the value of t, take the following steps:

Combine similar terms: 1.50t - t = $12.50 - $10

Add similar terms = 0.50t = 2,50
