Answer:
2x - 48
Step-by-step explanation:
If it is 48 less, then it is -48. Next is 2x because it is twice a number.
If P(x)=x²+x+7 and Q(x)= 3x² -1, find Q( – 10).
Answer:
Q(- 10) = 299
Step-by-step explanation:
Q(- 10) = 3.(- 10)² - 1
= 3 . 100 - 1
= 300 - 1
= 299
=> Q(- 10) = 299
Write $\frac 15+\left(\frac 15\right)^2+\left(\frac 15\right)^3+\left(\frac 15\right)^4$ as a decimal
Answer:
0.2496
Step-by-step explanation:
what you could do is make the all the 1/5 into 2/10's.
then you could multiply all of them (2/10) squared (2/10) cubed and (2/10)^4
now you would have 2/10 4/100 8/1000 16/10000
now you can change it into decimals and add
0.2 +0.04+0.008+0.0016
now all you have to do is add when you do you get 0.2496
there are many ways you could do this problem but this is the most efficient becuause I used another way but it was not helpfull.
Answer: .2496
Aops Question
Step-by-step explanation:
This problem becomes easier if we write $\dfrac{1}{5}$ as $\dfrac{2}{10}$, so that all the denominators in our sum are powers of 10. Then
\begin{align*}
\frac15 + \left(\frac15\right)^2 + \left(\frac15\right)^3 + \left(\frac15\right)^4
&= \frac2{10} + \left(\frac2{10}\right)^2 + \left(\frac2{10}\right)^3 + \left(\frac2{10}\right)^4 \\
&= \frac2{10} + \frac4{100} + \frac8{1000} + \frac{16}{10{,}000} \\
&= 0.2 + 0.04 + 0.008 + 0.0016 \\
&= \boxed{0.2496}.
\end{align*}

[tex]\frac{5x+20}{8x^{5} }[/tex]·[tex]\frac{x}{x^{2} -16}[/tex]
Answer:
First, you have to factorize the expressions :
[tex] \frac{5x + 20}{8 {x}^{5} } \times \frac{x}{ {x}^{2} - 16} [/tex]
[tex] = \frac{5(x + 4)}{8 {x}^{5} } \times \frac{x}{(x + 4)(x - 4)} [/tex]
Second, you have to cross out the similar expressions :
[tex] = \frac{5}{8 {x}^{5} } \times \frac{x}{(x - 4)} [/tex]
Third, you have to multiply both fractions :
[tex] = \frac{5x}{8 {x}^{5}(x - 4) } [/tex]
Lastly, you have to simplify :
[tex] = \frac{5}{8 {x}^{4}(x - 4) } [/tex]

Put these numbers from least to greatest 0.51, 3/4, 0.59, 3/8, 0.24, 0.517
Answer: 0.24, 3/8, 0.51, 0.517, 0.59, 3/4
Step-by-step explanation:
First you will have to convert the 3/4 and 3/8 to a decimal number. By doing this 3/4 turns into 0.75 and the 3/8 becomes 0.375. After this step you then arrange the numbers for the lowest of 0.24 then the 3/8 (0.375) next 0.51 after that is 0.517 then 0.59 and final after that 3/4
Breanna thought of a number, added 6 to it, multiplied it by 6, subtracted 6 from her answer, and then divided it by 6. She got a final number of 10. What was her starting number?
Answer:5
Step-by-step explanation:
If you look at the question in reverse you can backtrack your way through. Take 10 and instead of dividing, multiply it by 10, which is 60, add 6 instead of subtracting, which is 66, divide by 6 instead of multiplying, which is 11 and finally subtract 6 instead of adding, which is 5. Use five and try the question over to make sure you calculated correct.
Triangle ABC is shown the measure of the interior angle at point A is 40 and the exterior angle point C is 102
Answer:
∠C (Interior) =78°
∠B (Interior) = 62°
Step-by-step explanation:
Given:
∠A (Interior) = 40°
∠C (exterior) = 102°
Computation:
∠C (Interior) = 180° - 102°
∠C (Interior) =78°
∠B (Interior) = 180° - ∠A (Interior) - ∠C (Interior)
∠B (Interior) = 180° - 78° - 40°
∠B (Interior) = 180° - 118°
∠B (Interior) = 62°
Write a linear equation for the graph in point-slope form. Show your work. (2 points)
Use your equation to determine how long Grace was at birth. Show your work and explain how you can check your result using your knowledge of rate of change. (3 points)
Based on the data, how long do you predict baby Grace will be at 36 months of age? Use the rate of change to justify your answer. Does your answer make sense? Explain. (2 points)
The point-slope intercept equation is y - 20 = 3/4(x - 4).
The rate of change is 3/4.
At 0 months (at birth), Grace was 17 inches long.
At 36 months, Grace would be 44 inches long.
How to Create a Linear Equation?A linear equation of a graph can be represented in point-slope form as y - b = m(x - a), where (a, b) is a point on the graph and m is the slope.
Find the Slope (m) using two points (4, 20) and (8, 23):
Slope (m) = change in y/change in x = (23 - 20)/(8 - 4)
Slope (m) = 3/4
Substitute (a, b) = (4, 20) and m = 3/4 into y - b = m(x - a):
y - 20 = 3/4(x - 4) [point-slope intercept equation]
At birth, months would be x = 0. To find how long Grace was at birth, substitute x = 0 into y - 20 = 3/4(x - 4) to find the value of y:
y - 20 = 3/4(0 - 4)
y - 20 = 3/4(-4)
y - 20 = -3
y - 20 + 20 = -3 + 20
y = 17
This means that, at 0 months (at birth), Grace was 17 inches long.
At 36 months, substitute x = 36 into y - 20 = 3/4(x - 4) to find the how long Grace was (y):
y - 20 = 3/4(36 - 4)
y - 20 = 3/4(32)
y - 20 = 24
y - 20 + 20 = 24 + 20
y = 44
At 36 months, Grace would be 44 inches long.

Step-by-step explanation:
Step one:
given
a man buys eggs at RS 9.60 per dozen
what is the unit cost of the dozen of eggs?
unit cost = 9.60/12
= $0.8 per egg
He sold 20 eggs for RS 18
the unit selling price = 18/20
=$0.9 per egg
the percent gain is
=0.8/0.9*100
=0.888*100

Suppose f(x)=x^2+9x+8
1. Suppose F(x) is obtained by reflecting the graph over the y-axis. Find a formula for F(x).
Suppose g(x)=x^19-8x^6-x^5+7x^2+x+9.
1. Reflected over x-axis vertically
2. Reflected over y-axis horizontally
Using translation concepts, the functions are given as follows:
1. F(x) = x² - 9x + 8.
2. [tex]G(x) = x^{19} + 8x^6 - x^5 - 7x^2 + x - 9[/tex]
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
In item 1, the function is:
f(x) = x² + 9x + 8.
When the function is reflected over the y-axis, we have that:
F(x) = f(-x),
Hence:
F(x) = (-x)² + 9(-x) + 8.
F(x) = x² - 9x + 8.
For item 2, the function is:
[tex]g(x) = x^{19} - 8x^6 - x^5 + 7x^2 + x + 9[/tex]
When the function is reflected over the x-axis, we have that:
G(x) = -g(x).
Hence:
[tex]G(x) = -x^{19} + 8x^6 + x^5 - 7x^2 - x - 9[/tex]
When the function is reflected over the y-axis, we have that:
Hence:
G(x) = G(-x).
[tex]G(x) = -(-x)^{19} + 8(-x)^6 + (-x)^5 - 7(-x)^2 - (-x) - 9[/tex]
[tex]G(x) = x^{19} + 8x^6 - x^5 - 7x^2 + x - 9[/tex]

Antonio harvested 100 1/2 kg of fruits from his farm and he sold 30 2/3 kg of durian and 34 5/6 kg of mangosteen. How many kilograms of fruits were not sold?
Answer:
the number of kilograms of fruits that are not sold is 35
Step-by-step explanation:
The computation of the number of kilograms of fruits that are not sold is as follows:
The equation would be
100 1 ÷ 2 - 30 2 ÷ 3 - 34 5 ÷ 6
100 3 ÷ 6 - 30 4 ÷ 6 - 34 5 ÷ 6
99 9 ÷ 6 - 30 4 ÷ 6 - 34 5 ÷ 6
69 5 ÷ 6 - 34 5 ÷ 6
35
Hence, the number of kilograms of fruits that are not sold is 35
Explain why the formula for sample variance is different from the formula for population variance. Why is it inappropriate to use the formula for population variance in calculating the variance of a sample
Step-by-step explanation:
The difference in the formula of population and sample variance can be explained as:
Population variance is said to be the value of variance that is calculated from population data, whereas sample variance refers to the variance calculated from sample data. This is the reason why value of denominator in the formula for variance in case of sample data is ‘n-1’, while it is ‘n’ for population data. Hence, the result of both variance and standard deviation derived from sample data is larger than those found out from population data.

The bakers at Healthy Bakery can make 170 bagels in 2 hours. How many
bagels can they bake in 14 hours? What was that rate per hour?
Given:
The bakers at Healthy Bakery can make 170 bagels in 2 hours.
To find:
How many bagels can they bake in 14 hours and the rate per hour.
Solution:
We have,
Number of bagels the bakers can bake in 2 hours = 170 bagels
Number of bagels the bakers can bake in 1 hours = [tex]\dfrac{170}{2}[/tex] bagels
= 85 bagels
Therefore, the average rate is 85 bagels per hour.
Number of bagels the bakers can bake in 14 hours = [tex]14\times 85[/tex] bagels
= 1190 bagels
Therefore, the bakers can bake 1190 bagels in 14 hours.
