Answer:
17
Step-by-step explanation:
3(-2)^2 - 2(-2) + 1
12 - 2(-2) + 1
12 + 5
17
Answer:
f(-2) = 3(-2)² - 2(-2) + 1 = 17
Step-by-step explanation:
f(x) = 3x² - 2x + 1
f(-2) = 3(-2)² - 2(-2) + 1
= 3 × 4 + 4 + 1
= 12 + 5
f(-2) = 17
Thus, f(-2) = 3(-2)² - 2(-2) + 1 = 17

Find the area of the composite figure.
Round to the nearest hundredth.
(10 Points)
20.9m
14.3m
22.7 m
Answer:
474.43 m²
Step-by-step explanation:
The shape is composed of a rectangle and a parallelogram
Area of the composite shape = area of the rectangle + area of the parallelogram
= Length*Width + base*height
Where,
Length = 20.9 m
Width = 14.3 m
base = 20.9 m
height = 22.7 - 14.3 = 8.4 m
Area = 20.9*14.3 + 20.9*8.4
Area = 298.87 + 175.56
= 474.43 m²
write an ordered pair corresponding to the point

Rearrange the parts of the parallelogram to form a rectangle. Find the area of the parallelogram and the area of the rectangle. How are the areas related?
Make a copy of the trapezoid to form a parallelogram. Find the area of the trapezoid and the area of the parallelogram. How are the two areas related?
When we do this, the base of the parallelogram has length b 1 + b 2, and the height is the same as the trapezoids, so the area of the parallelogram is (b 1 + b 2)*h. Since the two trapezoids of the same size created this parallelogram, the area of one of those trapezoids is one half the area of the parallelogram
Estimate 85.77-62.396 by first rounding each number to the nearest whole number
Answer:
24
Step-by-step explanation:
85.77-62.396 estimated by rounding each number to the nearest whole number is 24. I got this by first rounding 85.77 to 86. I then rounded 62.396 to 62. Next, I did 86-62= 24.
So, the answer is 24.

Ringo deposited some money into a savings account. He earned 4% interest. After 6 months he earned $21 in interest. How much money did he start with?
I NEED HELP PLEASE!!
Answer:
$1050
Step-by-step explanation:
I = PRT / 100
I = 21
P = ?
R = 4%
T = 6 months = 0.5 yr
P = 100I / RT
P = (100 * 21) / (4 * 0.5)
P = $1050

Three people take 2 1⁄2( two and a half ) hours to deliver leaflets to 270 houses
Assuming all people deliver leaflets at the same rate, how long will it take five people to deliver leaflets to 450 houses?
Give your answer in hours and minutes
9514 1404 393
Answer:
2 hours 30 minutes
Step-by-step explanation:
Effort is measured in people-hours per house. Here, the effort to deliver one leaflet is ...
(3 people)(2.5 hours)/(270 houses) = 1/36 people-hours/house
Then the number of hours (h) for 5 people and 450 houses is ...
(5 people)(h hours)/(450 houses) = 1/36 people-hours/house
h = (1/36)(450/5) = 2.5
It will take 2 hours 30 minutes to deliver to 450 houses.
_____
Alternate solution
The time is (assumed) inversely proportional to the number of people, so increasing the number of people from 3 to 5 multiplies the time by 3/5. The time is proportional to the number of houses, so increasing the number of houses from 270 to 450 multiplies the time by 450/270 = 5/3. The time for the second task is (3/5)(5/3) = 1 times the time for the first task.
2 1/2 hours is 2 hours 30 minutes.

Read the description of a proportional relationship.
Ezra is finding the perimeter of different-sized regular pentagons. There is a proportional relationship between the side length of the regular pentagon in inches, x, and the perimeter of the regular pentagon in inches, y.
A regular pentagon with 1-inch side lengths has a perimeter of 5 inches. Write the equation for the relationship between x and y.
y=
Answer:
Step-by-step explanation:
The answer is 15
the equation for the relationship between x and y is,
y = 5x
What is perimeter?A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference. Calculating the perimeter has several practical applications.
Perimeter refers to the total outside length of an object,
The equation given in the problem is
y = 5x
where
the side length of the regular pentagon in inches, x,
the perimeter of the regular pentagon in inches, y
Hence, the equation for the relationship between x and y is,
y = 5x

Answer:C
Step-by-step explanation:
The expression that most adequately expresses the model would be:
C). 3 × 2/5
What is a fraction?A fraction is described as an expression employed to denote a segment or section belonging to a larger whole.
In the given question, it can be observed that the model contains 10 parts in total with a division of 5 each into 2 parts.
Since the division of 2 is made thrice, it gives 3 × 2/5 which makes the third option the correct one.
Thus, option C is the correct answer.

Vending machines can be adjusted to reject coins above and below certain weights. The weights of legal U.S. quarters have a normal distribution with a mean of 5.67 grams and a standard deviation of 0.07 gram. If a vending machine is adjusted to reject quarters that weigh more than 5.81 grams and less than 5.53 grams, what percentage of legal quarters will be rejected by the vending machine
Answer: The percentage of legal quarters will be rejected by the vending machine = 2.275%
Step-by-step explanation:
Given: The weights of legal U.S. quarters have a normal distribution with a mean of 5.67 grams and a standard deviation of 0.07 gram.
Let x be the weights of legal U.S. quarters .
Required probability: [tex]P(x<5.53)+P(x>5.81)[/tex]
[tex]=P(\dfrac{x-\mu}{\sigma}<\dfrac{5.33-5.67}{0.07})+P(\dfrac{x-\mu}{\sigma}>\dfrac{5.81-5.67}{0.07})\\\\=P(z<-4.857)+P(z>2)\approx0.02275 \ \ \ [By\ P-value\ calculator][/tex]
The percentage of legal quarters will be rejected by the vending machine = 2.275%
