Write the function notation for the transformation that would change f(x) to have a vertical
koban [17]

Function is 4 - \frac{f(x)}{8}.

<u>Step-by-step explanation:</u>

We have a function notation for the transformation that would change f(x) to have a vertical  compression by a factor of \frac{1}{8}, reflection over the x axis, up 6 and right 2.

<u>Step 1:</u>

Vertical compression by a factor \frac{1}{8} , this means decreasing value of function by a factor of  \frac{1}{8}. Function becomes \frac{f(x)}{8}.

<u>Step 2:</u>

Reflection over x-axis means rotating f(x) by 180° over origin . Function now is -\frac{f(x)}{8}.

<u>Step 3:</u>

Up 6 , means value of function is increased by 6 , Function now is \frac{-f(x)}{8}  + 6.

<u>Step 4:</u>

Right 2, means shifting function to 2 units on right side i,e, on x-axis.

∴Function finally becomes, \frac{-f(x)}{8} +6 - 2 which is 4 - \frac{f(x)}{8}.

John has a die and a coin. The die is labeled 1 through 6 and the two sides of the coin are heads and tails. The tables below sh
Alenkasestr [34]

Answer:

n = 60

Step-by-step explanation:

Total outcomes, while tossing a coin are 2, given as:

{Heads, Tails}

The probability of getting a heads up, while tossing the coin is:

P(Heads) = Favorable Outcome/Total Outcomes

P(Heads) = 1/2 = 0.5

Now, the total outcomes, while rolling a die are 6, given as:

{1, 2, 3, 4, 5, 6}

5 of these numbers are factors of 12, which are:

{1, 2, 3, 4, 6}

Thus, the probability of getting a factor of 12, while rolling a die is:

P(Factor of 12) = Favorable Outcome/Total Outcomes

P(Factor of 12) = 5/6 = 0.83

So, the probability of getting both heads and factor of 12 will be:

P(Heads and Factor of 12) = P(Heads ∪ Factor of 12)

P(Heads and Factor of 12) = P(Heads) * P(Factor of 12) = 0.5 * 0.83

P(Heads and Factor of 12) = 0.417 = 41.7%

So, for 144 trials, the number of trials in which we get heads and factor of 12, are given by:

n = P(Heads and Factor of 12) * 144

where,

n = no. of trials John would expect to roll a number on the die that is a factor of 12 and toss a coin that lands heads-up out of next 144 trials

n = 0.417 * 144

<u>n = 60</u>

a windowpane is 5.7 Inches by 7.1 inches. what is the distance between opposite corners of the windowpane? if necessary, round t
nikitadnepr [17]

Answer:

the distance is 9.1 inches (please give brainliest)

Step-by-step explanation:

we must use the pythagorean theorem:

5.7^2 + 7.1^2 = c^2

(c being the distance being the two corners)

c^2 = 82.9

c = sqrt(82.9) ≈ 9.1

Find a solution to the system. Make sure to write as a coordinate.
RUDIKE [14]

Answer:

x=2, y=3

Step-by-step explanation:

This is a <u>system of equations</u>.

To solve a system of equations, we use the substitution method.

We can plug in the first equation, x=2y-4, into the value for <em>x</em> in the second equation. Now, the second equation looks like this:

2*(2y-4)+y=7

We simplify and solve for <em>y</em>:

→ 4y-8+y=7

→ 5y=15

→ y=3

Now, we plug in the value for <em>y</em>, which is 3, into either equation. I will just use the first equation:

→ x=2*3-4

→ x = 2

Let me know if my explanation is unclear.
