which if the following describes the transformation of the graph y=x^2 in graphing y=-x^2-5​

Answer:

∠ZPB and ∠APZ are two adjacent supplementary angles

Step-by-step explanation:

we know that

Two angles are Adjacent when they have a common side and a common vertex

Two angles are supplementary if their sum is equal to 180 degrees

In this problem we have that

[tex]m\angle ZPB=90^o[/tex] ----> given problem

[tex]m\angle APZ=90^o[/tex] ----> given problem

so

[tex]m\angle ZPB+m\angle APZ=180^o[/tex]

∠ZPB and ∠APZ are supplementary angles

and

∠ZPB and ∠APZ have a common side (ZP) and a common vertex (P)

therefore

∠ZPB and ∠APZ are two adjacent supplementary angles

Answer: ∠ZPB and ∠APZ are two adjacent supplementary angles

Final answer:

To maintain the same weekly revenue after reducing her pot price from $24 to $16, a potter working 4 days a week must increase her daily production from 14 pots to 21 pots, which is an increase of 7 pots per day.

Explanation:

The question involves a potter who initially makes 14 pots per day and works 4 days a week, charging $24 per pot. To find out by how many pots per day she must increase her production after lowering her price to $16 per pot, to make the same amount of money, we first calculate her current weekly revenue:

After reducing the price to $16 per pot, we need to determine how many pots per day she needs to sell to maintain the same weekly revenue of $1,344:

Therefore, she needs to sell 7 more pots per day (21 pots - 14 pots) to maintain her weekly revenue.

Answer:

The coordinates of point Q will be given by (11,-2)

Step-by-step explanation:

See the attached diagram.

Given that R is the midpoint of PS and Q is the midpoint of RS.

Therefore, the point Q divides the line PS in the ratio 3 : 1.

Now, coordinates of P are (8,10) and that of point S is (12,-6).

Therefore, the coordinates of point Q will be given by  

[tex](\frac{3\times 12 + 1 \times 8}{3 + 1}, \frac{3 \times (- 6) + 1 \times 10}{3 + 1})[/tex]  

= (11,-2) (Answer)

First, do distributive property:

2(5+3x)+(x+10)  Distribute the 2 to the 5 and the 3x; multiply them

10+6x+x+10      Since (x+10) would be 1 times x and 10, it's just x+10

Then, do communitive property:

10+6x+x+10     What we found in the last step, now combine the like terms

20+7x              This is what you get since 10+10=20 and 6x+x=7x

The answer:

20+7x or 7x+20

Answer:

Andrew did not reason that he could save the $10 per hour he would make cutting lawns by preparing his own meal

Step-by-step explanation:

If Andrew cuts lawns for $10 per hour, he would have $4 more to save by preparing his own meal rather than spending the $4 at Taco Bell

Answer:

Instead of spending time making food, he drives and buys food by a total of $4.

Now, he is not considerating the amount of gas that he is spending by going to buy food and returning.

Also, he was not working, so he is not producing money at the beginning, so making his own lunch actually does not implies that he stops working and loses money.

Answer:

The solution of the inequality is:

[tex]x>2[/tex]

Step-by-step explanation:

Given inequality:

[tex]-1 >-2(x - 4)-5(4x-7)[/tex]

Solving the inequality.

Using distribution.

⇒ [tex]-1 >(-2x) +((- 4)(-2))+(-5\times4x)+((-5)(-7))[/tex]

⇒ [tex]-1 >-2x +8-20x+35[/tex]

Combining like terms

⇒ [tex]-1 >-2x-20x+35+8[/tex]

⇒ [tex]-1 >-22x +43[/tex]

Adding [tex]22x[/tex] both sides.

⇒ [tex]-1+22x >-22x +43+22x[/tex]

⇒ [tex]-1 +22x> 43[/tex]

Adding 1 both sides.

⇒ [tex]-1+1 +22x> 43+1[/tex]

⇒ [tex]22x>44[/tex]

Dividing both sides by 22.

⇒ [tex]\frac{22x}{22}>\frac{44}{22}[/tex]

⇒ [tex]x>2[/tex]

Thus, the solution of the inequality is:

[tex]x>2[/tex]

Polar form: (r,θ)

Using these formulas:

x²+y²=r²

tan(θ)=y/x

We have the point (1,1) in cartesian coordinates. We need to find r and θ to get it in polar form.

r²=1²+1²

r²=2

r=±√2

tan(θ)=1/1

tan(θ)=1

θ=π/4 radians or 45 degrees

Polar coordinates: (√2,π/4)

Step-by-step explanation:

8 litres (amount of 20% solution needed) and 7 litres for (amount of 50% solution needed)

Step-by-step explanation:

Let consider ‘x’ for 20% acid solution and (15 – x) for 50% acid solution. And so, the equation would be as below,

                         20% in x + 50% in (15 – x) = 15 litres of 34%

Convert percentage values, we get

                              0.20(x) + 0.50 (15 – x) = 15 (0.34)

                              0.20 x + 7.5 – 0.50 x = 5.1

                              -0.3 x + 7.5 = 5.1

                              0.3 x = 7.5 – 5.1

                              0.3 x = 2.4

[tex]x = \frac{2.4}{0.3} = 8 litres (amount of 20 \% solution needed)[/tex]

Apply ‘x = 8’ value in (15 – x) we get,

                         15 – 8 = 7 litres

The value of 7 litres for (amount of 50% solution needed)

Answer: [tex]S_{29}[/tex] = 2001

Step-by-step explanation:

Since the sequence is an arithmetic sequence , it means that a common difference must exist.

Let the terms in the sequence be [tex]T_{1}[/tex] , [tex]T_{2}[/tex] , [tex]T_{3}[/tex] , [tex]T_{4}[/tex] , ...

Then common difference = [tex]T_{2}[/tex] - [tex]T_{1}[/tex] = [tex]T_{3}[/tex] - [tex]T_{2}[/tex] = 8

That is , the common difference (d) = 8

The formula for calculating sum of  n terms is given by :

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a + (n-1)d ]

Where ;

n = number of terms

a = first term

d = common difference

From the question :

n = 29

a = -43

d = 8

Substituting into the formula , we have

[tex]S_{29}[/tex] = [tex]\frac{29}{2}[/tex] [ 2{-43} + (29-1)(8) ]

[tex]S_{29}[/tex] = [tex]\frac{29}{2}[/tex] (-86 +224)

[tex]S_{29}[/tex] = [tex]\frac{29}{2}[/tex] ( 138)

[tex]S_{29}[/tex] = [tex]\frac{4002}{2}[/tex]

[tex]S_{29}[/tex] = 2001

25 cakes can be completely decorated using 4 gallons of icing.

Step-by-step explanation:

Given:

4 gallons of icing

16 cups =1 gallon

No. of icing cups = [tex]4\times16[/tex] cups

       =64 cups

No. of cups required to decorate and frost a cake= 4% of total no. of icing cups

          = [tex]\frac{(4\times64)}{100}[/tex]

          = 2.56

2.56 cups of icing is required to decorate each cake.

Maximum no. of cakes decorated = [tex]\frac{ (64\times1)}{2.56}[/tex]

                    = 25

25 cakes can be completely decorated using 4 gallons of icing.

Explanation:

When the inequality symbol is replaced by an equal sign, the resulting linear equation is the boundary of the solution space of the inequality. Whether that boundary is included in the solution region or not depends on the inequality symbol.

The boundary line is included if the symbol includes the "or equal to" condition (≤ or ≥). An included boundary line is graphed as a solid line.

When the inequality symbol does not include the "or equal to" condition (< or >), the boundary line is not included in the solution space, and it is graphed as a dashed line.

Once the boundary line is graphed, the half-plane that makes up the solution space is shaded. The shaded half-plane will be to the right or above the boundary line if the inequality can be structured to be of one of these forms:

Otherwise, the shaded solution space will be below or to the left of the boundary line.

_____

Just as a system of linear equations may have no solution, so that may be the case for inequalities. If the boundary lines are parallel and the solution spaces do not overlap, then there is no solution.

_____

The attached graph shows an example of graphed inequalities. The solutions for this system are in the doubly-shaded area to the left of the point where the lines intersect. We have purposely shown both kinds of inequalities (one "or equal to" and one not) with shading both above and below the boundary lines.

Answer:

x^3 - 3x^2 - 3x + 9 + (-36/(x+3))

OR

x^3 - 3x^2 - 3x + 9 - (36/(x+3))

Step-by-step explanation:

First set the divisor equal to 0:

x + 3 = 0

Subtract 3 from both sides

x = -3

This is what you'll divide the dividend by in synthetic division.

Take the coefficents of each term in the dividend. Do not forget the 0 placeholders:

x^4 + 0x^3 - 12x^2 + 0x -9

Coefficents: 1. 0.  -12. 0 -9.

Please see the image for the next steps.

The remainder is -36. Put the remainder over the divisor and add it to the polynomial (shown in image)

-36/(x+3)

Divide using synthetic division the remainder is -36. Put the remainder over the divisor and add it to the polynomial -36/(x+3).

First set the divisor equal to 0:

x + 3 = 0

Subtract 3 from both sides

x = -3

This is what you'll divide the dividend by in synthetic division.

Take the coefficents of each term in the dividend. Do not forget the 0 placeholders:

[tex]x^4 + 0x^3 - 12x^2 + 0x -9[/tex]

Step-by-step explanation:

The diagram shows Pascal's triangle. Pascal's triangle is a triangular array of the binomial coefficients.

The entry in the [tex]n^{th}[/tex] row (start counting rows from 0) and [tex]k^{th}[/tex] column (start counting columns from 0) of Pascal's triangle is denoted by

[tex]C^n_k=\left(\begin{array}{c}n\\ k\end{array}\right)[/tex]

Coefficient 20 stands in 6th row, then n = 6 and in 3rd column, so k = 3.

Hence,

[tex]20=C^6_3=\left(\begin{array}{c}6\\ 3\end{array}\right)=\dfrac{6!}{3!(6-3)!}[/tex]

Answer: [tex]4\ feet[/tex]

Step-by-step explanation:

The exercise provides you the following Quadratic function:

[tex]h(t)=4+60t-16t^2[/tex]

You know that it represents the height (in feet) of the ball as a function of the time (in seconds) since the ball hit the bat.

Based on this, you can conclude that when the ball strikes the bat the time in seconds is:

[tex]t=0[/tex]

Therefore, in order to calculate the height in feet of the ball when it strikes the bat, you need to subsititute [tex]t=0[/tex] into the function and    then evaluate.

So, you get:

 [tex]h(0)=4+60(0)-16(0)^2\\\\h(0)=4[/tex]
