Answer:

[tex]K=6[/tex]

Step-by-step explanation:

In f(x) graph the vertex is at x=4

In g(x) the vertex at x=-2

so, the graph is shifted 6 units left. when the graph is shifted k units left then f(x) becomes f(x+k)

here the  graph is 6 units left so.. K= 6

Answer:

D

Step-by-step explanation:

The required focus of the parabola (x - 1)^2 = 12(y + 2) is (1, 1). Option D is correct.

Given that, equation of the parabola,

A parabola is cross-section cut out of the cone and represented by an equation [tex]y = 4ax^2[/tex]. Where a is focus.

Here,
[tex](x - 1)^2 = 12(y + 2)[/tex]
Simplify the above parabola equation to stand equation
[tex]y = \frac{1}{4(f-k)} (x-h)^2 + k[/tex]
[tex]y =\frac{1}{4(1-(-2))} (x - 1)^2 - 2[/tex]
Now comparing above the equation,
vertex of a parabola,
h = 1 and k = -2

And focus
So the coordinate of the focus of the parabola = (h, f)
= (1, 1)      

Thus, the required focus of the parabola (x - 1)^2 = 12(y + 2) is (1, 1). Option D is correct.

Step-by-step explanation:

The computation of the area of the horizontal cross section of the cyclinder is given below:

In the case when it is a circle

The area of the circle is

= πr^2

= 3.14 × (2.75 ÷ 2)^2

= 11.873 inches^2

In the case when it is a rectangle

The area of the rectangle is

= 6 × 2.75

= 16.5 inches^2

Hence, the above show the calculations

The area of the horizontal cross section.

When circular is [tex]11.873 inches^2[/tex]

When it is rectangular [tex]16.5inches^2[/tex]

The computation of the area of the horizontal cross section of the cylinder

The area of the circle is[tex]=\pi r^{2}[/tex]

use the given value in above formula we get,

[tex]= 3.14 \times (\frac{2.75}{2} )^2[/tex]

[tex]= 11.873 inches^2[/tex]

when it is a rectangle then the area of the rectangle is

[tex]= 6 \times 2.75[/tex]

[tex]= 16.5 inches^2[/tex]

Therefore,the area of the horizontal cross section.

when circular is [tex]11.873 inches^2[/tex]

When it is rectangular [tex]16.5inches^2[/tex]

Answer:

11/4

Step-by-step explanation:

Multiply the denominator by the whole number and add it to the numerator and keep the denominator the same therefore it would be 11/4.

Your answer is B. 205.

Because when you subtract 270 - 100 it equals 170 then you add 170 + 125 which equals 295 then you subtract 500 - 295 it equals 205 which is your answer!

Hi there!

[tex]\large\boxed{x = 16}[/tex]

.5x + 3 = 11

To begin, we can subtract 3 from both sides:

.5x + 3 - 3 = 11 - 3

.5x = 8

To cancel out the .5, we must multiply both sides by 2: (.5 × 2  = 1)

2(.5x) = 2(8)

x = 16.

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the types of injuries and the frequency of each injury are not given.

A general way to solve a question like this, is as follows;

First: Calculate the total frequency.

Assume the given dataset is:

[tex]\begin{array}{cc}{Injury} & {Frequency} & {Dislocation} & {20} & {Strain} & {5} & {Broken\ Bone} & {10} & {Bruise} & {15} \ \end{array}[/tex]

The total frequency is:

[tex]Total =20 + 5 + 10 + 15[/tex]

[tex]Total =50[/tex]

Next, write out the frequency of broken bone injuries

[tex]Broken\ Bone = 10[/tex]

Calculate the probability by dividing the number of broken bone by the total frequency

[tex]Pr= \frac{10}{50}[/tex]

[tex]Pr = 0.20[/tex]

Answer:

Yes, there is enough paint to cover the table top.

Step-by-step explanation:

We are told in the above question that the table top is round = circular

The area of a circle = πr²

Diameter = 6 feet

Radius = Diameter/2 = 6 feet/2 = 3 feet

Area of the table top= π × 3²

= 28.27 square feet

We are told that the a sample jar will cover 30 square feet.

Therefore, yes, there is enough paint to cover the table top.

Answer:

2.25$

Step-by-step explanation:

The cost of each cupcake the food court mall sells is $2.28.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, Desiree works at a dessert counter in the food court of a mall. The dessert counter sells cupcakes and cookies.

Each cookie costs $1.25 and assuming the cost of the cupcake is x.

∴ (1.25×12) + (8x) = 33.30.

15 + 8x = 33.30.

8x = 18.3
