Answer:
Steps are detailed below.
Step-by-step explanation:
The steps to determine the absolute maximum and minimum values of a continuous function on a closed interval are;
For example, if we have a function f(x) = x³ - 3x + 2 on the interval (-3, 4)
The steps are;
Step 1:
We will find the first derivative of f(x) which is; f'(x) = 3x² - 3.
Then we will find the critical values of this derivative. The critical values are the values of x that makes f'(x) = 0. But these critical values must fall in between the given interval (-3, 4)
Step 2:
Plug in the critical values gotten in step 1 above into the original f(x) function and note down the answers.
Step 3;
Plug in the endpoint values on the interval (-3, 4) given in the question into the original f(x) function and note down the answers.
Step 4;
The highest and lowest values of f(x) gotten in steps 2 & 3 are the absolute maximum and absolute minimum values respectively of the continuous function f(x).

How many different rays can be formed from five collinear points?
Answer:
eight
Step-by-step explanation:
There are eight different rays that can be formed from five collinear points.
What are the collinear points?Collinear points are defined as points that are along a straight line represented by a collinear. Because a straight line may be drawn continuously between any two points, they are always collinear.
If five points are collinear, it means they lie on a single straight line.
The number of rays is determined by n collinear points
In general, for n collinear points, there are 2(n−1) different rays.
As per the question, substitute the value of n = 5 for the above formula,
⇒ 2(5−1)
⇒ 2 x 4
⇒ 8
Thus, there are eight different rays can be formed from five collinear points.

A polling company reported that % of surveyed adults said that Complete parts (a) through (d) below.
a. What is the exact value that is 37% of 1018?
b. Could the result from part (a) be the actual number of adults who said that Why or why not?
1. No, the result from part (a) could not be the actual number of adults who said that because that is a very rare opinion.
2. No, the result from part (a) could not be the actual number of adults who said that because a count of people must result in a whole number.
3. Yes, the result from part (a) could be the actual number of adults who said that because the polling numbers are accurate.
4. Yes, the result from part (a) could be the actual number of adults who said that because the results are statistically significant.
c. What could be the actual number of adults who said that The actual number of adults with this opinion could be 296. (Type an integer or a decimal.)
d. Among the 1018 respondents, 415 said that cellular phones are not at all harmful. What percentage of respondents said that cellular phones are not at all harmful?
Answer:
a) 376.66
b) Option 2: No, the result from part (a) could not be the actual number of adults who said that rising gas prices are "quite annoying" because a count of people must result in a whole.
c) 377
d) 40.77%
Step-by-step explanation:
a) 37% of 1018 is;
37/100 × 1018 = 376.66
b) Thus, the result in a above is not a whole number. Thus;
No, the result from part (a) could not be the actual number of adults who said that rising gas prices are "quite annoying" because a count of people must result in a whole.
c) from a above a, we got a value of 376.66.
Now the actual number would be preferably an integer. Thus, actual number is approximately 377.
d) percentage of respondents said that cellular phones are not at all harmful = 415/1018 × 100% = 40.77%
Phil Dunphy, a real estate agent, is considering whether he should list an unusual $262,023 house for sale. If he lists it, he will need to spend $3,111 in advertising, staging, and fresh cookies. The current owner has given Phil 6 months to sell the house. If he sells it, he will receive a commission of $19,752. If he is unable to sell the house, he will lose the listing and his expenses. Phil estimates the probability of selling this house in 6 months to be 40%. What is the expected profit on this listing?
Answer: $4,789.80
Step-by-step explanation:
If Phil is able to sell the house, the profit he makes will be;
= Commission - expenses
= 19,752 - 3,111
= $16,641
If he is unable to sell in 6 months he will lose $3,111.
His expected profit will be a weighted average of the two possibilities;
= (40% * 16,641) + ( 60% * -3,111)
= 6,656.40 + (-1,866.6)
= $4,789.80

Salena needs to purchase 9 skirts for a new job. her friend, Jamie goes with her each of the skirts costs $41. Salena says that she can find the total cost by multiplying 9 and 4 and adding that to product of 9 and 1. Jamie disagrees and says that she needs to find the product of 9 and 40 and add that to the product of 9 and 1. Who is correct and why?
Answer:
Jamie is correct. This is because 41 is a combination of 40 and 1. Salena thinks that the 4 is just a 4, however, the 4 is in the tens place, so the 41 without the 1 is 40. The answer to this 41 times 9 is 369. Not 45.
Step-by-step explanation:
Each skirt is $41
Salena needs 9
(9*40) + (9*1)
360 + 9
$369
What is the value of x?
sin(x+22)°=cos(2x−7)°
Answer:
x is 25
Step-by-step explanation:
sin(x+22)° = cos(2x-7)°
since,
sin theta = cos(90 - theta)
we can substitute that in (let theta = x + 22)
sin(x + 22) = cos(90 - (x+22))
we also know
sin(x+22) = cos(2x-7)
thus cos(90 - (x+22)) = cos(2x-7)
cos(90 - (x +22)) = cos(2x-7)
cos(90 - x -22) = cos(2x - 7)
cos(68 - x) = cos(2x - 7)
68 - x = 2x - 7
68 + 7 = 2x + x
75 = 3x
x = 75/3
x = 25

The base of a triangle is 12 inches greater than the height. If the area is 80 square inches, find the length of the base
PLEASE HELP
Answer:
Step-by-step explanation:
Because the area of a triangle you have to divide by 2 and then you get the area right so we multiply 80 x 2 = 160 is the area of the square which you divide by 2 but we are not going to do that. now we have to get 2 lengths with 12 difference so we have to just do trial and error method.
Simplify the following expression, 3/8 divided by 1/4
The required simplified product is 3/2.
Given that fractions 3/8 ÷ 1/4.
To divide two fractions by multiplying the first fraction with the reciprocal of the second fraction.
Let a, b, c and d be any real numbers. Consider a/b ÷ c/d that gives
[tex]\frac{a}{b}[/tex] ÷ [tex]\frac{c}{d}[/tex] = [tex]\frac{a}{b}[/tex] × [tex]\frac{c}{d}[/tex].
That implies, [tex]\frac{3}{4}[/tex] ÷ [tex]\frac{1}{4}[/tex] = [tex]\frac{3}{8}[/tex] × [tex]\frac{4}{1}[/tex] = [tex]\frac{3}{2}[/tex].
Hence, the required simplified product is 3/2.
