Answer: p(x) = $1*(2)^x
Step-by-step explanation:
First, the father pays him $1 for only starting the work, and for each hour, the payment is doubled.
So after the first hour, the payment wil be 2*$1 = $2.
After the second hour, the payment will be 2*(2*$1) = $1*(2)^2
After another hour, the payment will be 2*($1*(2)^2) = $1*(2)^3
We already can see the pattern here, after x hours, the payment will be:
p(x) = $1*(2)^x
This is the function that models this situation.

Step-by-step explanation:
Given that ∆BCD ~ ∆BFG, therefore the ratio of their corresponding side lengths will be equal.
Thus:
[tex] \frac{BC}{BF} = \frac{BD}{BG} [/tex]
Substitute
[tex] \frac{17x + 13}{36} = \frac{154}{42} [/tex]
Cross multiply
[tex] 42(17x + 13) = 154(36) [/tex]
[tex] 714x + 546 = 5,544 [/tex]
[tex] 714x = 5,544 - 546 [/tex] (subtraction property of equality)
[tex] 714x = 4,998 [/tex]
Divide both sides by 714
x = 7

Find the input (x)of the function y =25/6x-34 if the output (y) is 16. x=__
Answer:
The input is x = 12.
Step-by-step explanation:
We are given the following function:
[tex]y(x) = \frac{25x}{6} - 34[/tex]
We have to find the input(x) if the output y is 16. So
[tex]16 = \frac{25x}{6} - 34[/tex]
[tex]\frac{25x}{6} = 16 + 34[/tex]
[tex]\frac{25x}{6} = 50[/tex]
[tex]25x = 6*50[/tex]
Simplifying both sides by 25
[tex]x = 6*2 = 12[/tex]
The input is x = 12.

Alex scored 98,72, and 87 on his first three math test. What must he score on the next test to have an average of at least 86 (P.S I need quickly no need to rush yourself just quickly)
Answer:
[tex]\huge\boxed{\text{At least an } 87\%}[/tex]
Step-by-step explanation:
In order to find what score Alex must earn to have an average of 86 on all his tests, we need to first note what the formula to find the average of a data set is.
[tex]\displaystyle \frac{x_1+x_2+...x_n}{n}[/tex]
What the formula means is that we have to add up all the values then divide by the total number of values.
Let's represent our unknown number as [tex]x[/tex].
[tex]\displaystyle \frac{98+72+87+x}{4} \geq 86[/tex] (since we want AT LEAST an 86).
Let's solve this inequality for x.
[tex]\frac{98+72+87+x}{4} \cdot 4 \geq 86 \cdot 4[/tex] [tex]98+72+87+x \geq 344[/tex] [tex]257 + x \geq 344[/tex] [tex]257 + x - 257 \geq 344 - 257[/tex] [tex]x \geq 87[/tex]So, Alex must score at least an 87% on his next quiz to have an average of 86%.
Hope this helped!

Answer: it’s 20
Step-by-step explanation: QR= 6, RS= 6, ST= 8 because 14-6=8
Answer:
The answer is 20
Step-by-step explanation:
If R is in the middle of s and q and it equals 6, then you just have to multiply it by 2. You will get 12 for QS. Now to find the whole thing, subtract 6 from 14 to get 8 and add 8 to 12 to get 20.
20 is your answer.

g+5>12 solution please i don’t know how to do this
Answer: g > 7
Graph has an open circle at 7 on the number line, shading to the right
================================================
Explanation:
Think of it like saying "I have a number, and I add on 5. The result is something larger than 12". You can guess and check your way to the answer, but the quickest way is to subtract 5 from both sides.
We subtract to undo the addition happening to the 'g'.
g+5 > 12
g+5-5 > 12-5
g > 7
So the number is larger than 7. For instance, if g = 8, then,
g+5 > 12
8+5 > 12
13 > 12
This is a true statement.
-------------------------
If you need to graph the solution, then you'll have an open circle at 7 on the number line. The open circle says to the reader "don't include this value as part of the solution set". Shade to the right of the open circle to describe all values larger than 7.
In summary, the graph has an open circle at 7 and shading to the right.
