2. What are the coordinates of point C?

Answer:

A single pencil costs $0.85 and a single eraser costs $0.60

Answer: The cost of one eraser is $0.6

Step-by-step explanation:

When solving this problem, it's best to set up a system of equations. Let pencil = p and eraser = e.

p = $0.25 + e

8p = $6.80

Now, we can use the second equation to solve for p by dividing both sides by 8. 6.8/8 = 0.85. Therefore, p = $0.85.

Then, use the value of p to find e by plugging the value of p we just found back into the first equation we wrote. Doing so, we get $0.85 = $0.25 + e.   To solve for e, we must subtract 0.25 from both sides, giving use 0.85-0.25 = 0.6

Therefore e = $0.6, so the cost of one eraser is $0.6 or 60 cents.

Answer:  [tex]f^{-1}(x) = -\sqrt{36-x^2}[/tex]

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

Here are the steps to find the inverse

[tex]f(x) = \sqrt{36-x^2}\\\\y = \sqrt{36-x^2}\\\\x = \sqrt{36-y^2} \ \text{ swap x and y; solve for y}\\\\x^2 = 36-y^2\\\\x^2+y^2 = 36\\\\y^2 = 36-x^2\\\\y = \sqrt{36-x^2}\\\\f^{-1}(x) = \sqrt{36-x^2}\\\\[/tex]

Now this would be the answer if our original domain was [tex]0 \le x \le 6[/tex]

However, that's not the case and instead our domain is [tex]-6 \le x \le 0[/tex]

Reflecting any (x,y) point in this domain restriction, over the the line y = x, will have us land on a point with a negative y value. This is because the inverse will swap the x and y values.

Therefore, the inverse function must ultimately be negative.

Currently [tex]f^{-1}(x) = \sqrt{36-x^2}[/tex] is positive since the result of any square root is never negative.

To fix this, we stick a negative out front to get the final answer being [tex]f^{-1}(x) = -\sqrt{36-x^2}[/tex]

The graph represents a function because it passes the vertical line test thus the best option B.

The graph is "pictorial representation or diagram that represents data or value in an organized manner".

If "all vertical line intersect the curve at most once, then the curve represents function" is called vertical line test for function.

According to the question,

In this graph, for one value of x, the graph has one value for y.

Hence, the graph represents a function because it passes the vertical line test thus the best option B.

Answer:

C

Step-by-step explanation:

There’s nothing hard with this

You need to know special right triangles

This is a 30,60, 90 triangle

We automatically know becuase theres. Right angle (90) and a 60 degree angle

now the formula is the smallest side is (n) {I’m using N becuase theres already an X) or in this case, 6

The hypotenuse, the one directly above the 2nd biggest side, or the diagnoal side is 2n or (12). Now we know what X is in this situation which is 12. So that narrows it to 2 answers

Now the side on the bottom of the hypotenuse, the second biggest side is used in the formula N[tex]\sqrt{3}[/tex]. So we know what N is in the beginning, 6 so we just plug that in and well get C. Attached is a photo on q 30, 60, 90 special right triangle

Answer:

16xb

Step-by-step explanation:

In algebra the numbers are multiplied with the numbers and the variables are multiplied with the variables.

In this question we would multiply x with b and 4 with 4 .

Multiplying x with b would give xb and 4 with 4 gives 16

So the answer will be 16xb

For example if you have 3x and 10 z the answer would be 30xz

Answer:

The next number is -12 ⇒ B

Step-by-step explanation:

Let us solve the question

∵ The pattern is 2,916, -972, 324, -108, 36, ....

→ All the given numbers are divisible by 3 because the sum of

  the digits of each number can divide by 3

∵ The pattern has positive and negative numbers

∴ Each next term = the previous term ÷ -3

→ Let us do that to find the missing number

∵ 2916 ÷ -3 = -972

∵ -972 ÷ -3 = 324

∵ 324 ÷ -3 = -108

∵ -108 ÷ -3 = 36

→ Find the next number by divide 36 by -3

∵ 36 ÷ -3 = -12

∴ The next number is -12

Answer:

The answer is 5.48

Step-by-step explanation:

When rounding the hundredths (second number after the dot), you want to look at the number on the right. In this case, that number is 6.

Anytime the number to the right is more than 5, you make the number before it one number higher. Here, the 7 in 5.476 turns into 5.48.

After you've rounded, drop the number you looked at. So, no need for the 6 anymore!

Answer:

He needs 4 more pieces

Step-by-step explanation:

Here, we want to know the number of more string pieces that are needed

Firstly, we need to the number of string pieces obtained from the 8 2/5 inch piece

we divide 8 2/5 by 3/5

That will be;

42/5 * 5/3 = 14

So what he will get is 14 pieces from the 8 2/5 inch

The number of pieces needed is thus;

18-14 = 4

Answer:

The length of the wire is 3.24451394 × 10⁻⁹ cm

Step-by-step explanation:

The volume of the wire = 66 cm³

The diameter of the wire = 1 mile

We convert the volume from cm³ into mile³  to get;

66 cm³ = 1.5834 × 10⁻¹⁴ mile³

The volume = π × D²/4 × l

Where;

D = The diameter = 1 mile

l = The length of the wire

1.5834 × 10⁻¹⁴ = π × 1²/4 × l

The length of the wire = l = 1.5834 × 10⁻¹⁴/(π × 1²/4) = 2.0160475 × 10⁻¹⁴ mile

1 mile = 160,934.4 cm

2.0160475 × 10⁻¹⁴ mile = 2.0160475 × 10⁻¹⁴ × 160,934.4 cm = 3.24451394 × 10⁻⁹ cm  

The length of the wire = 3.24451394 × 10⁻⁹ cm
