Answer:

f(x)=1/16(x-2)^2+2

Step-by-step explanation:

The Equation can be written like this:

f(x) = 1/(4p)(x -h)^2 +(k-p)

where (h, k) is the focus, and p is half the distance between focus and directrix. Here, (h, k) = (2, 6) and p=(6-(-2))/2 = 4. So the equation is ...

 f(x) = 1/16(x -2)^2 +2

120

Step-by-step explanation:

because it is a obtuse and it cant be 100 because its too far so i guess it can be 120

Step-by-step explanation:

To divide by a fraction, we can invert the fraction and multiply.

So, 12 divided by 3/4 can be written as:

12 * 4/3

Simplifying this expression, we get:

= 48/3

= 16

Therefore, 12 divided by 3/4 is equal to 16.

12 divided by 1/3 is 1

9 divided by 1/4 is 2.25

1/8 divided by 4 is 0.5

12 divided by 1/3 is 4

To define Payroll tax.

Now, Payroll tax refers to the taxes that are deducted from an employee's wages or salary by their employer.

These taxes are withheld to fund various government programs and services.

Payroll taxes typically include federal, state, and local income taxes, as well as Social Security and Medicare taxes.

The amount of payroll taxes deducted from an employee's paycheck depends on factors such as income level, tax brackets, and the tax rates set by the applicable government authorities.

These taxes are then remitted by the employer to the appropriate tax agencies on behalf of their employees.

They are specifically related to employment income and play a crucial role in funding important government initiatives and social programs.

Step-by-step explanation:

Ok this is pretty simple. Slope intercept is by far the most simple way to write an equation given that it only has 2 pieces: the slope of the line and the value at which it crosses the y axis (so when x=0). Slope is usually represented by the varriable "m" and the y intercept is usually represented by the letter "b". (Don't ask me why they chose these 2 random letters. It's... it's just whatever... Go with it.) Thus, we have the equation y=mx+b. So anyways.. Slope is just the change in y divided by the change in x. To find this, we just take 2 random points on the graph, subtract the first y from the second y and divide that by the first x subtracted from the second x. Let's use (2,-9) and (4,-10) from this fun little graph you ever so generously provided for us.

I'm bad at transitions so here's the math:

(y2-y1)/(x2-x1)

((-10)-(-9))/(4-2)

-1/2 ------> Thats "m".

SOOO... the slope is -1/2. Cool. BUT WE ARENT DONE

The other thing we need is the y-intercept. You may find yourself asking "what is this... this THING... he speaks of?" Its where the line hits the y axis. Thats is. It's not that hard. In this case it's -8 so b=-8.

Now for the best part... LETS PLUG ALL THOSE DOOHICKEYS IN.

y=mx+b

m=-1/2

b=-8

y=-1/2x+-8-----> y=-1/2x-8

Answer:

(1/30π) x 6 cm = 0.06283185 x 6 cm = 0.376 cm.

Step-by-step explanation:

The distance travelled by the tip of the second hand of a clock in 1 minute, if the hand is 6 cm long, is approximately 3.6 degrees or approximately 0.06283185 radians. This is because the circumference of a complete circle is equal to 2π radians, and a clock face is divided into 60 equal parts, so each part is equal to 1/60 of 2π or 1/30π radians. To convert this to cm, you can multiply by the length of the second hand, which is 6 cm. Therefore, the distance travelled is (1/30π) x 6 cm = 0.06283185 x 6 cm = 0.376 cm.

Answer:

\(A=\frac{ab}{2}\) or \(A = a *\sqrt{c^2-a^2} /2\)

Step-by-step explanation:

Depending on the values you take depends on the equation you would use to solve for the area of a right triangle(the first answer accounts for measuring both arms(the sides connected to the 90 degree angle(a and b)), where as the second answer accounts for using the hypotenuse and one of the arms). That means that a 90 degree angle is involved, or as illustrated here, the square in the bottom right corner. If this were a non-right angle triangle, a different formula utilizing the height of the triangle would be used instead.

\(A = \frac{h_{b}+b}{2}\)

Since the right angle exists, a height is already given using one of the arms of the triangle in its place. We can also confirm it is a triangle by adding up all degrees of the triangle, in which it would equal 180 degrees confirming it is indeed a triangle as well.

By using trigonometric relations we will see that the area is:

How to find the area of one triangular section?

Remember that the area of a right triangle is equal to the product between the cathetus divided by 2.

Sadly, here we don't have the measures of any sides of the triangle, so getting the actual area is impossible, but if we assume that some dimension is given (like the height, let's say that is h).

h is the cathetus adjacent to the 60° angle, then the other cathetus (the bottom one) is given by:

tan(60°) = x/h

x = tan(60°)*h

Then our two catheti are h and tan(60°)*h.

This means that the area will be:

Here we only used trigonometric properties, so this area will work for any height given (always that the value of h is the cathetus adjacent to the 60° angle).

n(P∩Q) = 10.

A set is a grouping of well-defined, separate things. The term "well-defined" refers to a certain characteristic that makes it clear whether or not the provided object belongs to the set. The word "distinct" denotes that each item in a collection must be unique. The general formula for sets is n(A∪B) = n(A) + n(B) - n(A⋂B).

Given the value of n(p)=20, n(Q)=30, and n (PUQ)=40, to find n(P∩Q). Let's put these values in the general formula of the set.

n(P∪Q) = n(P) + n(Q) - n(P⋂Q)

40 = 20 + 30 - n(P⋂Q)

n(P⋂Q) = 10

therefore the value of n(P⋂Q) is 10.

Answer:

The range is 37, and the IQR is 23.

Step-by-step explanation:

A box plot (also known as a "box and whisker plot"), is a graph displaying the distribution of a set of data based on a five-number summary.

From the given information, the five-number summary of the Jumping Jacks box plot is:

The range is the difference between the maximum and minimum values. Therefore, the range for the data is:

\(\sf Range = 52 - 15 = \boxed{\sf 37}\)

The IQR is the difference between the upper quartile and the lower quartile. Therefore, the IQR for the data is:

\(\sf IQR = Q_3 - Q_1 = 49 - 26 = \boxed{\sf 23}\)

The range is 37, and the IQR is 23.

Part A: $2,400

Part B: $9,900

First, you need to find how much interest she is paying annually by taking the 8% and finding out what is 8% of $7,500. To do this, we can set two fractions up side by side, x/7,500 and 8/100. The denominators mean 100% of 7,500 is 7,500. The numerators mean that x is 8% of 7,500.

So to find x, we can cross multiply 7,500 and 8, giving us 60,000. Then we can divide 60,000 by 100, to give us 600. So x=600. 600 is how much interest costs for 1 year.

Now, to find how much interest is for 4 years, all we have to do is multiply 600 by 4. This gives us 2400. So, 4 years of interest costs her $2,400.

Her total balance after the 4 years is just the 4 year interest plus the amount borrowed. So 2,400 + 7,500. Giving us $9,900.
