This one just scares me how do i even figure this out?

Answers

Answer 1

Answer: Because the middle point is in the center of the square, the triangle containing angle 2 is isosceles and right (since two sides are equal to half the square's side length), so angle 2 measures (180-90)/2=45 degrees.

A pizza place offers 3 different cheeses and 8 different toppings. In how many ways can a pizza be made
with 1 cheese and 3 toppings?

Answers

The cheese can be any one out of 3 = 3 choices. For each of those . . .
The first topping can be any one of 8. For each of those . . .
The second topping can be any one of the remaining 7 . For each of those . . .
The third topping can be any one of the remaining 6 .

Total number of ways to assemble a pizza = (3 x 8 x 7 x 6) = 1,008 ways.

BUT . . .

You could choose the SAME 3 toppings in (3 x 2) = 6 different ways, and
nobody could tell the difference once they were selected. All 6 different
ways would result in the same pizza.

So, out of the 1,008 total different ways there are of choosing ingredients,
there are only ( 1,008 / 6 ) = 168 different and distinct pizzas.

$1\ cheese\ is\ choose\ from\ 3:\ \ \ {3 \choose 1} =3\nand\ 3\ toppings\ are\ choose\ from\ 8:\ \ \ {8 \choose 3} = (8!)/(3!\cdot(8-3)!)= (5!\cdot6\cdot7\cdot8)/(2\cdot3\cdot5!)=56 \n\na\ pizza\ can\ be\ made\ on\ \ 3 \cdot 56=168\ \ ways$

identify an equation in point-intercept form for the line parallel to y = -3x + 7 that passes through (2, -4)

Answers

Let's organize.
The question says to identify an equation in point-intercept form for the line that's parallel to y = -3x + 7 that passes through (2, -4).

If you need to find an equation in point-intercept form that passes through a point, you will substitute the coordinate in this formula:

-> y - yo = m (x - xo)

Where:

(2, -4) -> xo = 2 ; yo = -4
m = Slope

You don't have the slope, but you have the information that the line is parallel to y = -3x + 7. Then you need to know that to a line be parallel to another the Slopes of each other must be equal, mr = ms.

Let's find the slope of the equation given, it is in a slope-intercept form, so:

y = mx + b

R: y = -3x + 7 // I will call this one R line, and the other S.

mr = -3

If the mr = ms, and mr = -3, then the ms = -3 too.

S: y - yo = ms (x - xo) // (2, -4) & ms = -3

-> y - (-4) = -3 (x - 2)
-> S: y + 4 = -3 (x - 2) -> This is the point-slope form.

-> y = -3x + 6 - 4
-> S: y = -3x - 2 -> This is the slope-intercept form.

I didn't understand what is the point-intercept form that the question requests, but by logic, i think that's the point-slope form.

Answer: The equation in point-intercept form is: y + 4 = -3 (x - 2).

An air conditioning repair services charges $85.00 per hour, plus a diagnosis fee of $75.00. If the repair costs a total of $385.00, which of the following equations best represents the situation?

Answers

Answer:

you have to put in the answers.

Answer:

$385.00 = $85.00 * 3.647 + $75.00

Step-by-step explanation:

The equation that best represents the situation is:

Total Cost = Hourly Rate x Repair Time + Diagnosis Fee

In this case, the hourly rate is $85.00 and the diagnosis fee is $75.00. We are given that the total cost is $385.00. Let's represent the repair time as "t" in hours.

So, we can write the equation as:

$385.00 = $85.00 * t + $75.00

To solve for the repair time "t", we need to isolate the variable.

First, we subtract $75.00 from both sides of the equation:

$385.00 - $75.00 = $85.00 * t

Simplifying, we get:

$310.00 = $85.00 * t

Next, we divide both sides of the equation by $85.00 to solve for "t":

$310.00 / $85.00 = t

Using a calculator, we find that t is approximately 3.647, which means the repair time is approximately 3.647 hours.

Therefore, the equation that best represents the situation is:

$385.00 = $85.00 * 3.647 + $75.00

As x → −[infinity], y → ? As x → [infinity], y → ? Determine the end behavior for y = 8x^4 Determine the end behavior for y = -49 + 5x^4 + 3x Determine the end behavior for y = -x^5 + 5x^4 + 5

Answers

Problem 1

The end behavior of y = 8x^4 is:

$\text{As x} \to -\infty, \text{ y } \to \infty\n\text{As x} \to \infty, \text{ y } \to \infty$

In either case, y approaches positive infinity. This end behavior is the same as a parabola that opens upward. This applies to any even degree polynomial.

Informally we can describe the end behavior as: "Both endpoints rise up forever".

======================================

Problem 2

The end behavior of y = -49 + 5x^4 + 3x is the exact same as problem 1. Why? Because the degree here is 4. The degree is the largest exponent.

======================================

Problem 3

For this problem we have the polynomial y = -x^5 + 5x^4 + 5

This time the degree is 5, which is an odd number.

The end behavior would be

$\text{As x} \to -\infty, \text{ y } \to \infty\n\text{As x} \to \infty, \text{ y } \to -\infty$

Informally, we can state the end behavior as "Rises to the left, falls to the right".

The endpoints go in opposite directions whenever the degree of the polynomial is odd. Think of a cubic graph. The "falls to the right" is due to the negative leading coefficient.

I strongly recommend using a TI83, TI84, Desmos, or GeoGebra to graph out each polynomial so you can see what the end behavior is doing.
