c² - 6c - 40
Sum = -6
Product = -40
Factors= -10 , 4
c² - 6c -40 = c² - 10c - 4c - 10*4
= c(c - 10) - 4(c - 10)
= (c -10) (c -4)
e² + 10e +16
Sum = 10
Product = 16
Factors= 2 , 8
e² + 10e + 16 = e² + 2e + 8e + 2*8
= e(e + 2) + 8(e + 2)
= (e + 2)(e +8)
h² - 5h - 24
Sum = -5
Product = -24
Factors = 3 , -8
h² - 5h - 24 = h² + 3h - 8h - 3*8
= h(h + 3) - 8(h + 3)
= (h +3)(h - 8)
3x² - 5 x - 12
Sum = -5
Product = -12 * 3 = - 36
Factors = -9 , 4
3x² - 5x - 12 = 3x² - 9x + 4x - 4*3
= 3x(x - 3) + 4(x - 3)
=(x - 3) (3x + 4)
4x² + 4 x - 15
Sum = 4
Product = 4 * -15 = - 60
Factors = 10 , -6
4x² + 4x - 15 = 4x² + 10x - 6x - 3*5
=2x (2x + 5) - 3(2x +5)
= (2x + 5)(2x - 3)

Find the measures of the complementary angles that satisfy each case.
The measure of the first angle is 40° less than the measure of the second.
Answer:
25° and 65°
Step-by-step explanation:
1. 65°-25°= 40°
2. 90°-65°=25°
3. 90°-25°=65°
Therefore 25° and 65° fit the criteria, make sure to add the degrees symbol :)
Complementary angles have a sum of 90° thus measure of the first and the second angle is 25° and 65° respectively.
What is an angle?Angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.
Let's suppose the first angle is x while the second is y.
If two angles have a sum of 90° then they will be called as complementary angles since x and y are complementary.
x + y = 90
Now given that,
The measure of the first angle is 40° less than the measure of the second.
x = y - 40
x - y = -40
By adding both equations,
(x + y) + (x - y) = 90 + (-40)
2x = 50
x = 25
y = 90 - 25 = 65
Hence "The first and the second angle is 25° and 65° respectively".

Maggie plans to sell the bracelets she makes for a price of $5.50 each. For every bracelet she makes, she has costs of $0.05 for each of the 21 beads used, $0.74 for each of the two charms used, and $1.09 for the chain with clasp used. Which of these would result in Maggie NOT earning a profit on the sale of a bracelet?
Price of each bracelets , P = $5.50 .
Cost price = $0.05 for each of the 21 beads used + $0.74 for each of the two charms used + $1.09 for the chain with clasp used.
Cost price = $( 0.05×21 + 0.74×2 + 1.09 )
Cost price = $3.62 .
Now, profit is given by :
Profit = Selling price - Cost price
Profit = $(5.50 - 3.62)
Profit = $1.88
Therefore, she will not bear any loss.

Step-by-step explanation:
Advertisers contract with Internet service providers and search engines to place ads on websites. They pay a fee based on the number of potential customers who click on their ad. Unfortunately click fraud, the practice of someone clicking on an ad solely for the purpose of driving up advertising revenue, has become a problem. Forty percent of advertisers claim they have been a victim of click fraud. Suppose a random sample of 380 advertisers will be taken to learn more about how they are affected. What is the probability that the sample proportion will be with 0.04 of the population proportion?
Answer:
The probability that the sample proportion will be with 0.04 of the population proportion is 0.8904.
Step-by-step explanation:
Let p = proportion of advertisers who claim they have been a victim of click fraud.
The population proportion is, p = 0.40.
A random sample of 380 advertisers is selected.
According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:
[tex]\mu_{\hat p}=p[/tex]
The standard deviation of this sampling distribution of sample proportion is:
[tex]\sigma_{\hat p}=\sqrt{\frac{p(1-p)}{n}}[/tex]
The sample selected is too large, i.e. n = 380 > 30.
Then the proportion of advertisers who claim they have been a victim of click fraud can be approximated by the normal distribution.
The mean and standard deviation of this sampling distribution of sample proportion is:
[tex]\mu_{\hat p}=p=0.40\\\\\sigma_{\hat p}=\sqrt{\frac{p(1-p)}{n}}=\sqrt{\frac{0.40(1-0.40)}{380}}=0.025[/tex]
Compute the probability that the sample proportion will be with 0.04 of the population proportion as follows:
[tex]P(p-0.04<\hat p<p+0.04)=P(\frac{-0.04}{0.025}<\frac{\hat p-\mu_{\hat p}}{\sigma_{\hat p}}<\frac{0.04}{0.025})[/tex]
[tex]=P(-1.60<Z<1.60)\\=P(Z<1.60)-P(Z<-1.60)\\=0.94520-0.05480\\=0.8904[/tex]
Thus, the probability that the sample proportion will be with 0.04 of the population proportion is 0.8904.

What are the solutions to the equation 0 = x2 – x –6? Select two options
x = –3
x = –2
x = 0
x = 2
x = 3
Answer:
-2 or 3
Step-by-step explanation:
Step 1: Factor equation.
(x+2)(x−3)=0
Step 2: Set factors equal to 0.
x+2=0 or x−3=0
x=−2 or x=3
-2 and 3 are the solutions to the equation x² – x – 6 = 0
To determine the solutions of the equation x² – x – 6 = 0
x² - x - 6 = 0
x² - 3x + 2x - 6 = 0
x (x - 3) + 2(x + 3) = 0
(x + 2) (x + 3) = 0
(x + 2) = 0
x = - 2......(1)
(x + 3) = 0
x = - 3..........(2)
x = −2 or x = 3
Therefore, -2 and 3 are the solutions to the equation x² – x – 6 = 0.

What is the formula for distance?
Formula:
Hope this helped, if not, don’t spam.
The formula in finding the distance between two points is given below:
[tex] \boxed{\bold{\:\:d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \:\:}}[/tex]Now, you know the distance formula. So, let us try solving a sample problem using the distance formula.
Sample problem: Determine the distance between P(3, 2) and Q(10, 2).
From inspection on the given problem:
(x_1, y_1) = (3, 2)(x_2, y_2) = (10, 2)Substitute the given values into the distance formula and solve for PQ:
[tex]\sf PQ = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex][tex]\sf PQ = \sqrt{(10 - 3)^2 + (2 - 2)^2}[/tex][tex]\sf PQ = \sqrt{(7)^2 + (0)^2}[/tex][tex]\sf PQ = \sqrt{49 + 0}[/tex][tex]\sf PQ = \sqrt{49}[/tex][tex]\bold{PQ = 7 \: units}[/tex]Therefore, the distance between two points is 7 units.

Now, wasn't that easy? Try this other sample problem:
Find the distance between P(1, 3) and Q(7, 11).From the sample problem above, you may solve it on your own to enhance your skill on calculating the distance.

Jason had three more than four times the amount of money that Jeff has. Together they have $72. How much money does each person have?
Answer:
Jason has $58.20 and Jeff has $13.80.
Step-by-step explanation:
Let x represent the amount of money Jason has, and y represent the amount of money Jeff has.
We know that together they have $72. So, we can write the following equation:
[tex]x+y=72[/tex]
We know that Jason has three more than four times the amount of money Jeff has. So:
[tex]x=3+4y[/tex]
This is a system of equations. We can solve it by using substitution. Let's substitute the second equation into the first. This yields:
[tex](3+4y)+y=72[/tex]
Combine like terms:
[tex]5y+3=72[/tex]
Subtract 3 from both sides:
[tex]5y=69[/tex]
Divide both sides by 5:
[tex]y=69/5=\$13.80[/tex]
So, Jeff has $13.80
We know that Jason has three more than four times the amount of money Jeff has.
Therefore, Jason has:
[tex]x=13.8(4)+3[/tex]
Multiply and add:
[tex]x=\$58.20[/tex]
So, Jason has $58.20 and Jeff has $13.80.
And we're done!
