Answer:
- 4x² - 8x - 3
Step-by-step explanation:
We want to calculate
1 - (2x + 2)² ← expand using FOIL
= 1 - (4x² + 8x + 4) ← distribute parenthesis by - 1
= 1 - 4x² - 8x - 4 ← collect like terms
= - 4x² - 8x - 3

Find the area of a regular pentagon with apothem length 5 in. Round to the nearest tenth.
A, B, C, D, E and F are points on a circle. put crosses on the ends of the line that is a diameter of the circle
9514 1404 393
Answer:
AD is the diameter
Step-by-step explanation:
Angles in a triangle have a sum of 180°, so inscribed angle B is 80° and inscribed angle E is 90°.
An inscribed angle subtends an arc that is twice its measure, so arcs ABD and AED are both 180°. That makes chord AD a diameter.
Points A and D need your cross markings. AD is a diameter of the circle.

What is the radius of a circle with circumference 17 mm? Round to the nearest tenth. Use 3.14 for TT.
Answer: 2.7mm
Step-by-step explanation:
The formula for the circumference of a circle is given as 2πr. In thkw case, thw circumference is 17mm.
Therefore, 2πr = 17
2 × 3.14 × r = 17
6.28r = 17
r = 17/6.28
r = 2.7mm
Therefore the radius of the circle is 2.7mm
this probability distribution shows the typical distribution of pitches thrown to a batter in a given at-bat in a baseball game. Find the probability that the pitcher will throw 4 or fewer pitchers to a batter.
Answer = 9/10
Explanation:
Add up all the frequencies along the bottom row: 15+20+40+15+10 = 100
There are 100 pitches total. Ten of which occurs when the pitcher throws 5 times at the batter, as shown in the far right-most column. This means 100-10 = 90 occurrences happen when the pitcher throws 4 or fewer pitches to the batter.
The probability your teacher wants is therefore 90/100 = 9/10. This answer is in fraction form. It is equivalent to the decimal form 0.9
Answer:
The answer is 0.9
Step-by-step explanation:
The answer is 0.9

Answer:
Austin will have to buy 180 squares of carpeting.
Step-by-step explanation:
First find the dimension of the room. We do that by multiplying the width times the length and then subtracting the cut out region in the top right. And, in order to know how big that region we cut out is, we have to do a little subtraction.
We know the room is 18' long on the left side and 12' long on the right side. We subtract 12 from 18 to get 6, and we know that the cut out region is 6' long. We do the same thing with the width, 25' wide at the bottom minus 10' wide at the top and we see that the cut out is 15' wide.
18 x 25 = 450
6 x 15 = 90
450 - 90 = 360. The area of the room is 360 [tex]ft^{2}[/tex]
Each piece of carpet is 2' by 1'. So for every 2' long, the piece of carpet is 1' wide. Each carpet piece will cover 2 [tex]ft^{2}[/tex]. Divide 360 by 2 and you get 180.
On a coordinate plane, 2 parallelograms are shown. The first parallelogram has points A (negative 4, 4), B (negative 2, 4), C (negative 5, 1), D (negative 2, 1). The second parallelogram has points A prime (negative 2, 5), B prime (1, 5), C prime (negative 3, 2), D prime (0, 2).
Which rule represents the translation from the pre-image, ParallelogramABCD, to the image, ParallelogramA'B'C'D'?
T1, –2(x, y)
T1, 2(x, y)
T–2, 1(x, y)
T2, 1(x, y)
Answer:
D
Step-by-step explanation:
Trust the process
The translation from the pre-image, Parallelogram ABCD, to the image, Parallelogram A'B'C'D' will be; (d) T2, 1(x, y)
How to determine the transformation rule?Given that the parallelogram ABCD is shifted to the right by 2 units and shifted up by 1 unit to get parallelogram A'B'C'D'
This transformation rule is represented as given;
(x,y) -> (x + 2,y + 1)
This transformation rule can be rewritten
T2, 1(x, y)
Hence, the translation from the pre-image, Parallelogram ABCD, to the image, Parallelogram A'B'C'D' would be;
(d) T2, 1(x, y)

Please help ASAP!!!! You have a bag of change. Your bag consist of 5 Quarters, 20 Pennies, 10 Dimes and 5 Nickels. If you take one out to give to a friend, what are than chances that you would pull a Nickle then a Penny without replacing them. Placing your answer in
simplest fraction form.
Answer:
5/78 chance to get a Nickel and then a penny without replacing
Step-by-step explanation:
The bag contains a total of 40 coins which show that the probability of getting a Nickel is 5/40 and the probability of getting a penny after taking out a nickel is 20/39. In order to find the Probability of two events together you must multiply the probabilities so
(5/40) * (20/39) = 100/1560 = 5/78
Madison earned $80 last month pet sitting in her
neighborhood. She spent $54 and put the remainder of the
money in her piggy bank. What percent of her allowance did
Madison put in her piggy bank?
Answer:
32.5%
Step-by-step explanation:
80 - 54 = $26 in the piggy bank
80/100% = 26/x%
x = 32.5%
The money put in the piggy bank in percent is 32.25%.
What is percentage?A percentage is a value that indicates 100th part of any quantity.
A percentage can be converted into a fraction or a decimal by dividing it by 100.
The given problem can be solved as follows,
The remaining money put in piggy bank is $80 -$54 = $26
In order to calculate the percentage, take the ratio of the remaining money to the total earning as follows,
Percent of money in piggy bank = 26/80 × 100
= 26 × 5/4
= 32.25%
Hence, the percentage of money put in piggy bank by Madison is 32.25%.
