3x^5 + 12x^4 − 36x^3
Answers
Answer: 3x^3(x - 2)(x + 6)
Step-by-step explanation:
For this problem, you find a GCF first
The GCF in this case is 3x^3 since each term can be divided by both 3 and x^3
3x^3(x^2 + 4x - 12)
x * x = x^2
(-2 + 6) * x = 4x
-2 * 6 = -12
Since -2 and +6 work for the factors, the answer is 3x^3(x - 2)(x + 6)

find the slope, vertical intercept and horizontal intercept of (2,9) and (4,3)
Answers
Answer:
M = - 3
Step-by-step explanation:
Find the Slope:
Slope is equal to the change in y over the change in x
, or rise over run.
m = [tex]\frac{change in Y}{change in X}[/tex]
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
Substitute in the values of x and y into the equation to find the slope.
m = [tex]\frac{3-(9)}{4-(2)}[/tex]
Simplify.
m = [tex]\frac{-6}{2}[/tex]
m = -3
A tank has 55 gallons of water in it. The water drains from the tank at the rate of 3 gallons per minute. The function f(x) models the number of gallons of water in the tank after x minutes. Find f^-1(15) and explain what it represents.
Please help!!!!
Answers
Step-by-step explanation:
The initial amount is 55 gallons, and the rate is -3 gal/min. So using slope-intercept form, the equation is:
f(x) = -3x + 55
To find the inverse function, switch x and y, then solve for y.
x = -3y + 55
3y = -x + 55
y = (-x + 55) / 3
f⁻¹(x) = (-x + 55) / 3
Evaluated at x = 15:
f⁻¹(15) = (-15 + 55) / 3
f⁻¹(15) = 40 / 3
The original function told us number of gallons f(x) at time x.
The inverse function tells us time f⁻¹(x) at number of gallons x.
So there are 15 gallons in the tank after 40/3 minutes, or 800 seconds.

A fruit bowl contains 2 bananas, 5 oranges, and 4 apples. In simplest form, what is the ratio of apples to bananas in the fruit bowl? Explain what your ratio means in the context.
Answers
Answer:
2:1
Step-by-step explanation:
Since there are 4 apples and 2 bananas, the ratio of apples to bananas will be 4:2
This needs to be simplified, since both numbers are divisible by 2:
4:2 will simplify to 2:1
So, in simplest form, the ratio of apples to bananas is 2:1
In this context, this means there are 2 apples for every 1 banana in the fruit bowl.
The ratio of the apples to bananas in the fruit bowl is 2:1.
What is a ratio?A ratio in mathematics shows how many times one number is contained in another. For instance, if a dish of the fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six.
Given that there are 4 apples, 5 oranges, and 2 bananas in a fruit dish. The ratio of apples to bananas will be 4:2 because there are 2 bananas and 4 apples.
This needs to be simplified since both numbers are divisible by 2:
4:2 will simplify to 2:1
Therefore, the ratio of apples to bananas in the fruit bowl is 2:1.

Later, the teaching assistant in Nick’s physics course gives him some advice. "Based on past experience," the teaching assistant says, "working on 15 problems raises a student’s exam score by about the same amount as reading the textbook for 1 hour." For simplicity, assume students always cover the same number of pages during each hour they spend reading. Given this information, in order to use his 4 hours of study time to get the best exam score possible, how many hours should he have spent working on problems, and how many should he have spent reading?
Answers
Answer:
3 hours working on problems, 1 hour reading
Step-by-step explanation:
From the given information:
We learned that If Nick can attempt more than 15 problems in an hour, working on problems will helo and aid further his grade for that particular hour than reading would.
We know that the marginal gain for three hours is greater than 15. This implies that Nick would get better by spending 3 hours on problem-solving and the rest 1 hour on reading since the marginal gain for that an hour is one problem solved. Hence, it will be advisable to spend it on reading.

A certain form of cancer is known to be found in women over 60 with probability of 0.07. A blood test exists for the detection of the disease, but the test is not infallible. In fact, it is known that 10% of the time the test gives a false negative (i.e. the test incorrectly gives negative result when the woman actually has the cancer) and 5% of the time the test gives false positive (i.e. incorrectly gives a positive result when the woman actually does not have the cancer). What is the probability that a randomly selected woman over 60 will test positive?
Answers
Answer:
Throughout the segment below, the definition including its particular question is mentioned.
Step-by-step explanation:
The probability of developing cancer
= 0.07
The probability of someone not getting cancer
= 1 - 0.07
= 0.93
Provided that if women have cancer, the risk of someone not testing positive is:
= 0.10
Therefore, if a female requires cancer, the risk of testing positive
= 1 - 0.10
= 0.90
The Probability of positive test
= 0.055 (whenever a woman does not have cancer)
Therefore, whenever a woman does not have cancer, the risk of not testing positive will be:
= 1 - 0.05
= 0.955
Now,
By using the law of conditional probability, we get
⇒ [tex]P(\frac{B}{A} ) = \frac{P(A \ and \ B)}{P(A)}[/tex]
⇒ [tex]P (A \ and \ B) = P(A)\times P(B)[/tex]
⇒ P (having cancer as well as positive tests) = P(having cancer) × P(Effective results, because she has cancer)
⇒ [tex]0.07\times 0.90[/tex]
⇒ [tex]0.063[/tex]
Correspondingly,
P (not getting cancer and testing effective or positive)
= [tex]0.93\times 0.05[/tex]
= [tex]0.04655[/tex]
P (with a good test result)
= [tex]0.063 + 0.0465[/tex]
= [tex]0.1095[/tex]

Let a, b, and c be integers. Consider the following conditional statement:
If a divides bc, then a divides b or a divides c
Which of the following statements have the same meaning as this conditional statement, which ones are the negations, and which ones are not neither? Justify your answers using logical equivalences or truth tables.
A) If a does not divide b or a does not divide c, then a does not divide bc.
B) If a does not divide b and a does not divide c, then a does not divide bc.
C) If a divides bc and a does not divide c, then a divides b.
D) If a divides bc or a does not divide b, then a divides c. (e) a divides bc, a does not divide b, and a does not divide c.
Answers
Step-by-step explanation:
Given that the logical statement is
"If a divides bc, then a divides b or a divides c"
we can see that a must divide one either b or c from the statement above
A) If a does not divide b or a does not divide c, then a does not divide bc.
This is False because a can divide b or c
B) If a does not divide b and a does not divide c, then a does not divide bc.
this is True for a to divide bc it must divide b or c (either b or c)
C) If a divides bc and a does not divide c, then a divides b.
This is True since a can divide bc and it cannot divide c, it must definitely divide b
D) If a divides bc or a does not divide b, then a divides c.
This is True since a can divide bc and it cannot divide b, it must definitely divide c
E) a divides bc, a does not divide b, and a does not divide c.
This is False for a to divide bc it must divide one of b or c
