Answer:

The parent function of the given graph is:

                    Option: C

                   [tex]F(x)=x^4[/tex]

Step-by-step explanation:

Since, the graph of the function has four real zeros this means that the parent function must be a function of degree four.

Also, we know that if the degree of the parent function would be odd then the end behavior of the graph ( i.e. the behavior of the graph when x tends to infinity and when x tends to minus infinity ) must be in opposite direction.

But here the graph is in the same direction.

Hence, the degree of the function is four i.e. even.

From the given choice the choice that best matches the condition is:

a line parallel to a triangle’s side splits line AB into lengths of x-6 and x. the other side, line AC, is split into lengths of x+6 and x+20. what is the length of AC ?

Answers

Answer:

56

Step-by-step explanation:

Let's say that D is the point where AB is split, so AD = x-6 and DB = x.

And let's say that E is the point where AC is split, so AE = x+6 and EC = x+20.

Triangle ADE is similar to triangle ABC.  Therefore:

(x-6) / (x-6 + x) = (x+6) / (x+6 + x+20)

Solving:

(x-6) / (2x-6) = (x+6) / (2x+26)

(x-6) (2x+26) = (x+6) (2x-6)

2x² + 26x - 12x - 156 = 2x² - 6x + 12x - 36

2x² + 14x - 156 = 2x² + 6x - 36

14x - 156 = 6x - 36

8x = 120

x = 15

So the length of AC is:

AC = x+6 + x+20

AC = 2x + 26

AC = 2(15) + 26

AC = 56

A marketing firm tracks data on grocery store visits. In one study, it finds that the probability that a shopper buys bread during a visit to the grocery store is 0.60, and the probability that a shopper buys cheese is 0.25. Event A A shopper buys bread. Event B- A shopper buys cheese. A and B are independent events if____.

Answers

Answer: A and B are independent events if P(A∩B)=P(A).P(B)=0.15.

Step-by-step explanation:

Let A be the event that a shopper buys bread.

Let B be the event that a shopper buys cheese.

So, P(A∪B)=100

Probability that a shopper buys bread during a visit to the grocery store =n 0.60

P(A) = 0.60

Similarly, Probability that a shopper buys bread = 0.25

P(B) = 0.25

Since A and B are independent then,

[tex]P(A\cap B)=P(A).P(B)=0.60\times 0.25=0.15[/tex]

So, A and B are independent events if P(A∩B)=P(A).P(B)=0.15.

A textbook has a length of 6 inches, a height of y inches, and a width of x inches. If the length of the diagonal of the front cover is 8 inches and the length of the diagonal of the width is 7 inches, find the values of x and y.

Answers

Answer:

x = 2√7, y = √21

Step-by-step explanation:

The textbook has right angles, so we can use Pythagorean theorem to find the missing lengths.

For the triangle on top of the textbook:

c² = a² + b²

8² = 6² + x²

64 = 36 + x²

28 = x²

x = √28

x = 2√7

For the triangle on the side of the textbook:

c² = a² + b²

7² = x² + y²

49 = 28 + y²

21 = y²

y = √21

What are the coordinates of the circumcenter of this triangle?

Answers

ANSWER

The circumcenter is (2,1)

EXPLANATION

The midpoint of BC is (-3,2)

The equation of the perpendicular bisector of BC is x=2

The midpoint of AB is (-1,1)

The midpoint of AB is (-1,1)

The perpendicular bisector of AB is y=1.

These two lines intersect at (2,1).

The point of intersection of the perpendicular bisectors of a triangle is called the circumcenter of the triangle.

Based on the graph, the coordinates of the circumcenter of this triangle are (2, 1).

What is a circumcenter?

In Mathematics and Euclidean Geometry, a circumcenter is the point where perpendicular bisectors (right-angled lines to the midpoint) of the sides of a triangle meet together or intersect.

This ultimately implies that, the circumcenter of any triangle is always equidistant from all the rays (vertices) of that triangle.

By critically observing the graph of triangle ABC, we can logically deduce the following parameters;

Midpoint of BC = (-3, 2)Equation of the perpendicular bisector of BC: x = 2 ⇒(2, 0).Midpoint of AB = (-1, 1)Equation of the perpendicular bisector of AB: y = 1 ⇒(0, 1).

Based on the equation of the perpendicular bisector of BC and AB, the coordinates of the circumcenter are (2, 1).

Choose the graph that best represents the solution to the system of equations.
y=-x
y=x-1

Answers

First, rearrange the equations:

[tex]x + y = 0[/tex]

[tex] - x + y = - 1[/tex]

Then, do equation 1 minus equation 2 to cancel y:

[tex]x - - x = 2x[/tex]

[tex]0 - - 1 = 1[/tex]

[tex]2x = 1[/tex]

[tex]x = \frac{1}{2} [/tex]

Substitute x to find y:

[tex]y = - x = - \frac{1}{2} [/tex]

So the point of intersection is (1/2, -1/2), which is represented by graph 1.

Answer:

Given system of equations,

y = - x   ------(1)

y = x - 1 ------(2),

From equation (1) and (2),

-x = x - 1

-x - x = -1

-2x = -1

[tex]\implies x = \frac{1}{2}[/tex]

Again from equation (1),

[tex]y = -\frac{1}{2}[/tex]

Thus, the intersection point of the lines (1) and (2), is [tex](\frac{1}{2}, -\frac{1}{2})[/tex]

Hence, the below graph represents the solution to the system of equations.

A box of candy is shaped like a triangular pyramid the volume of the candy box measures 120 in squared 3 the area of the base of the candy box is 18 in squared 2 what is the height of the candy box

Answers

Final answer:

When using the formula for the volume of a pyramid, substituting the given values of base area and volume results in a candy box height calculation of 20 inches.

Explanation:

The question asks about the height of a box of candy shaped like a triangular pyramid, given the volume and the area of the base. The volume of a pyramid is given by the formula V = 1/3 * Base Area * height. In this case, the box volume equals 120 in³, and the base area equals 18 in². We can use these values to solve for the height.

By rearrangement of the formula, height = V / (1/3 * Base Area). If we plug in the values, height = 120 in³ / (1/3 * 18 in²) = 20in. Therefore, the height of the candy box is 20 inches.

Final answer:

The height of the candy box is 20 inches.

Explanation:

To find the height of the candy box, we need to use the formula for the volume of a triangular pyramid, which is V = (1/3) * A * h, where V is the volume, A is the area of the base, and h is the height.

We are given that the volume is 120 in³ and the area of the base is 18 in², so we can plug these values into the formula and solve for h.

120 = (1/3) * 18 * h

Simplifying the equation, we get:

360 = 18h

Dividing both sides by 18, we find that h = 20.

you invested your allowance of $270 which gets 15% compounded annually for 3 years. How much will you have in 3 years​

Answers

____________________________________________________

Answer:

Your answer would be $410.64

____________________________________________________

Step-by-step explanation:

In order to find the amount of money you would have in 3 years, you would have to multiply the principal each time by 15% 3 times.

We would start with our starting allowance, and multiply that by 1.15, and so on:

270 × 1.15 = 310.50

310 × 1.15 = 357.075

357.073 × 1.15 = 410.636

Since we have three numbers after the decimal, we would want to round up to the nearest hundredth because that's how the value of money works. Cents only go up to the hundredths place.

We would round the 6 to the three, in which would make the three turn into 4. When you round, the numbers 1-4 would keep the number before it the same, 5-9 would make the number before it go up by 1.

410.636 would turn into 410.64.

You would have $410.64 dollars in three years.

____________________________________________________

With a principal of $270 and an annual compound interest rate of 15%, your investment will grow to approximately $410.64 in 3 years.

To determine how much your investment of $270 will grow in 3 years with an annual compound interest rate of 15%, you can use the compound interest formula:

A = P(1 + r/n)ⁿᵗ

Where:

A = the future value of the investment/loan, including interestP = the principal investment amount ($270)r = the annual interest rate (decimal) (0.15)n = the number of times that interest is compounded per year (1, since interest is compounded annually)t = the number of years the money is invested or borrowed for (3)

Now plug in the values:

A = 270(1 + 0.15/1)¹*³

Simplify inside the parenthesis:

A = 270(1 + 0.15)³

Then:

A = 270(1.15)³

Calculate the exponent:

A = 270 * 1.520875

Finally, multiply:

A ≈ 410.64

After 3 years, your investment will grow to approximately $410.64.

This demonstrates the power of compound interest, which is an important concept to understand when investing.

the function f(x)=x-9 is shifted 2 units up and 3 units to the left. what is the new function

Answers

Answer:

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

Step-by-step explanation:

the original function f(x) = x - 9 is the parent function f(x) = x shifted down 9 units

from f(x) = x - 9, we are told that the function is shifted 2 units up, this is a vertical shift. so we add 2 to -9

-9 + 2 = -7

we now have f(x) = x - 7

next we are told that the function is shifted 3 units to the left. this is a horizontal shift. a horizontal shift looks similar to this:

f(x) = (x ± b)

if a function is shifted to the left, we would use an addition sign. if it was going to the right, we would use a subtraction sign

the function looks like the following when we apply the above knowledge

f(x) = (x + 3) - 7 this would be our new function

Final answer:

The new function will be f(x) = (x + 3) - 9 + 2.

Explanation:

The function given is f(x) = x - 9. When this function is shifted 2 units up and 3 units to the left, the new function is obtained by transforming the original function accordingly.

Shifting up by 2 units means adding 2 to the function, and shifting 3 units to the left means substituting x+3  for x.

Thus, the new function, after applying the transformations, is:

f(x) = (x + 3) - 9 + 2

Simplifying the above transformation, we get:

f(x) = x - 4

14.99 x 0.0625 = 0.936875.

This can be rounded to the nearest cent, or the hundredths place, and since the thousandths place is above five, round up to six. You now have a total of about $0.94.

I hope this helps & have a great day!

your answer is 0.936875

if p= (-2,7) find: Rx-axis(P)​

Answers

Answer:

P(-2,7)

P'(-2,-7), ANSWER

reflection across the x-axis rule:

(×,y) ===> (x,-y)

Easy way to do this is draw the point on graph paper and count the same units above/below the x-axis. This example you are 7 units above the x-axis so you would count 7 units below the x-axis giving you the point.

Final answer:

Reflection of a point across an axis involves flipping the sign of the coordinate for that axis. So the reflection of point P(-2,7) on the x-axis is P'(-2,-7).

Explanation:

The concept described in your question refers to the reflection of a point across the x-axis. Given a point P(-2,7), the reflection of this point across the x-axis, denoted as Rx-axis(P), reverses the sign of the y-coordinate. This happens because a reflection is a transformation that flips a figure across an axis of reflection.

So, if we consider P(-2,7) to reflect about the x-axis, we just switch the sign of y-coordinate. Therefore reflection of point P(-2,7) about x-axis will be P'(-2,-7).
