Step-by-step explanation:
if y varies inversely as x^2 then 1/y=x^2
note: there needs to be a constant
so let's just say that the constant is k
so we multiply k by x^2 to equal 1/y
1/y=(x^2)k
put in the values for x and y
x=4 and y=1/4
1/(1/4)=(4^2)k
4/16=k
1/4=k
now we insert k back into the first equation that we made
1/y=(x^2)(1/4)
put in the value for y
y=1
x=?
1/1=(x^2)(1/4)
4=x^2
±[tex]\sqrt{4}[/tex]=x
2=x and -2=x
Hope that helps :)
Answer:
x = 2
Step-by-step explanation:
y ∝ [tex]\frac{1}{x^{2} }[/tex] ⇒ y = [tex]\frac{k}{x^{2} }[/tex] (where k is the constant of proportionality)
k = x²y
When x = 4 and y = [tex]\frac{1}{4}[/tex],
k = (4)² × [tex]\frac{1}{4}[/tex]
= [tex]16 * \frac{1}{4}[/tex]
= 4
So, y = [tex]\frac{4}{x^{2} }[/tex]
When y = 1,
[tex]1 = \frac{4}{x^{2} }[/tex]
x² = 4
√x² = ±√4
∴ x = 2 or -2

You are using the equation 4(p – 7) = 44 to determine how many pictures can be saved at one time to the photo stream on your cell phone. Describe the operations in the order that you will perform them to solve the equation. (3 points)
Step-by-step explanation:
I know that 44÷4=11. So that means P must be 11. But since it's subtracted by 7 we must solve 11+7. Which is 18. So P=18.

Liam is setting up folding chairs for a meeting. If he arranges the chairs in 4 rows of the same length, he
has 7 chairs left over. If he arranges the chairs in 2 rows of that same length, he has 23 left over. How many
chairs does Liam have?
Liam has
chairs.
Answer:
Liam has 39 chairs.
Step-by-step explanation:
First you have to set up the equation -
4x + 7 = 2x + 23
then isolate the variables
4x - 2x + 7 - 7 = 2x - 2x + 23 - 7
2x = 16
x = 8
then substitute the variable with 8
4(8) + 7 = 39
2(8) + 23 = 39
Liam has 39 chairs.
Find the least whole number N greater than 40 for which:
( I ) N divided by 4 leaves a remainder of I. and
(2) N divided by 5 leaves a remainder of 3.
PLS HELP
Answer:
*Below*
Step-by-step explanation:
Let the number be N.
N divided by 4 leaves 1 as the remainder. This means N - 1 is divisible by 4.
So, we can write N - 1 = 4k1, where k1 is an integer 10 or greater
N divided by 5 leaves 3 as the remainder. This means N - 3 is divisible by 5.
So, we can write N - 3 = 5k2, where k2 is an integer 8 or greater
From above, we get 4k1 - 2 = 5k2
4k1 - 5k2 = 2
k1 = 13, k2 = 10 and the number is XXXXX = 4k1 + 1 = 4(13) + 1 = 53

A shirt normally sells for $65. It was on sale for 45% off the regular price for 3 days. On the forth day it increased by 10% more than the sales price. What is the new price? *
Answer:
$39.33 (rounded to nearest cent)
Step-by-step explanation:
Cost of shirt normally = $65
Cost of shirt for 3 days = [tex]\frac{100-45}{100}[/tex] × $65
= [tex]\frac{55}{100}[/tex] × $65
= $35.75
Cost of shirt on 4th day = [tex]\frac{100+10}{100}[/tex] × $35.75
= [tex]\frac{110}{100}[/tex] × $35.75
= $39.33 (rounded to nearest cent)

The sum of seven interior angle measurements in an octagon equal 835º. What is the angle measurement of the 8th angle? (Hint: An octagon has 8 sides.)
Answer:
The measurement of the eighth angle in the octagon is 245 degrees.
Step-by-step explanation:
The following formula calculates the total internal angles in an octagon:
Sum of the interior angle = (n - 2) * 180 degrees,
where n represents the polygon's number of sides. n = 8 for an octagon, so we have:
Interior angle sum = (8 - 2) * 180 = 1080 degrees.
Given that the sum of the seven inner angles is 835 degrees, we can construct the following equation:
835 + x = 1080
where x represents the eighth angle's degree measurement. After finding x, we obtain:
x= 1080 - 835
x = 245 degrees
The eighth angle of the octagon is therefore 245 degrees.

Find the range number of minutes.
Answer:
Range: 55
Step-by-step explanation:
Range = subtraction of the smallest number in the data set to the greatest number in the data set.
Greatest number: 1 hr (60 minutes)
Smallest number: 5 minutes
Range = 60 - 5
= 55

Given the set of data below, which measure(s) will change if the outlier is removed? (Check all that
apply.)
4, 7, 9, 9, 10
O mode
O median
O mean
Orange
Answer:
The mean will change. The range will change.
Step-by-step explanation:
The outlier is 4, it's the one number in the data that isn't close to the other numbers.
The data without the outlier will be 7, 9, 9, 10.
Mode: The mode will still be 9. It is still the number that appears the most in the data.
Median: The median WON'T change. The data is now one value shorter, but the median will still be 9. Before it was 9, and now it's still 9 ((9+9)/2).
Mean: The mean will change because we're excluding one value. Before, the mean was 7.8 (4+7+9+9+10=39, 39/5 = 7.8). NOW it is 8.75 (7+9+9+10=35, 35 / 4 = 8.75).
Range: The range will change. Before it was 10-4, now it is 10-7. The range was originally 6 and now it's 3.

Answer:
Exponential, quadratic, Linear
Step-by-step explanation:
So ok, let me give you a reminder on what these functions are.
So, a linear function is quite literally a strait line. Basically, the values of x and y are being added and subtracted by a ever-constant value.
Next is a quadratic function, which basically a u or upside-down u. The numbers increase, and then decrease, or vise versa. You can think of it like a bird flying up to the clouds, and then gliding back down.
Finally we have exponential functions. Which is a function that gets very, very high. This is because the number is squared over and over again. The bigger the x or y value gets, the bigger it will be next time its squared.
Just for a visual, I took some photos of the different types of functions.
Now, lets get into the problem.
For the first problem:
X is increasing by 1.
Y is increasing by....Lets see.
So it seems y is getting diving by 2 each time the x increases by 1.
It seems sort of like a linear function, right?
Well yes, but if you recall what I said above, the values are being added to or subtracted to. This is division, and is never a exact number. So it cant be that. The values dont go up and then back down, or vise versa like in a quadratic function. Well, could the value of y in this graph be squared by 1/2 to get our answer? Yes! So the answer must be exponential!
Now, lets try to speed through to the next ones.
We can see that the x is changing by 1, while the y changes by a odd and not always the same amount. This istantly means that it cannot be linear. It could be exponential, but if you look closly, you can see that at the end, the values start to decrease. Remember what I said about quadratic function? Then this must be a quadratic function!
That sums up our second function, lets look at our third.
The x is increasing by 1, and the y values are increasing by 6.
Hmm, it seems like each time x increases by 1, y increases by 6. This means it must be a linear function! After all, linear functions increase by a constant amount.
I hope this helps you with your problem and any you have in the future!
Good luck! ; )
