The formula is C=2(3.14)r
So we plug in the radius and multiply.
C=2(3.14)(5)
C=6.28x5
C=31.4

Factor the following quadratic expression.
2p2−19p+35
I don't get this
Answer:
(p - 7)(2p - 5)
Step-by-step explanation:
[tex]2 {p}^{2} - 19p + 35 \\ \\ = 2 {p}^{2} - 14p - 5p + 35 \\ \\ = 2p(p - 7) - 5(p - 7) \\ \\ = (p - 7)(2p - 5)[/tex]
A teacher gave a 3-question multiple choice quiz. Each question had 4 choices to select from. If the a student completely guessed on every problem, what is the probability that they will have 2 or less correct answers?
Answer:
0.9844
Step-by-step explanation:
This is a binomial probability problem.
Probability of getting a correct answer: p = 1/4
Probability of getting an incorrect answer: q = 3/4
Number of questions; n = 3
Thus;
probability of 2 or less correct answers is; P(x ≤ 2) = P(X = 2) + P(X = 1) + P(X = 0)
From binomial probability the formula is;
P(X = x) = C(n, x) × p^(x) × q^(n - x)
P(X = 2) = C(3, 2) × (¼)² × (¾)¹
P(X = 2) = 3 × 0.0625 × 0.75
P(X = 2) = 0.1406
P(X = 1) = C(3, 1) × (¼)¹ × (¾)²
P(X = 1) = 3 × 0.25 × 0.5625
P(X = 1) = 0.4219
P(X = 0) = C(3, 0) × (¼)^(0) × (¾)³
P(X = 0) = 0.4219
P(x ≤ 2) = 0.1406 + 0.4219 + 0.4219
P(x ≤ 2) = 0.9844

x
Answer:
[tex] {2}^{2} + {x}^{2} = {7}^{2} \\ {x}^{2} = 49 - 4 \\ x = \sqrt{45} \\ x = 6.708[/tex]
Answer:
By using Pythagoras theorem we get
H²=p²+b²
7²=2²+x²
X²=7²-2²
X=√(49-4)=√45=3√5

The author also uses _________ to describe the building and to give the reader a sense of "forbidding" or imposing fear.
repetition
imagery
irony
personification
Answer:
Imagery
How:

DEFINITIONS:Forbidding: Unfriendly or threatening in appearance.
Imposing fear: Someone noticeably feared by something/someone.
Find the value of each variable using sine and cosine. Round your answers to the nearest tenth.
Answer:
x ≈ 9.5 , y ≈ 15.3
Step-by-step explanation:
sin32° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{18}[/tex] ( multiply both sides by 18 )
18 × sin32° = x , then
x ≈ 9.5 ( to the nearest tenth )
cos32° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{y}{18}[/tex] ( multiply both sides by 18 )
18 × cos32° = y , then
y ≈ 15.3 ( to the nearest tenth )
The letters N, T, and O are arranged in a random order. What is the probability that the arrangement spells a three-letter word.
Express your answer as a simplified fraction.
Answer:
1/3Step-by-step explanation:
Three letters can be arranged in:
3! = 6 waysWe can spell two words from using the letters N, T, O:
"Not" and "Ton"So there are 2 favorable outcomes out of 6 total outcomes:
P(3-letter word) = 2/6 = 1/3Answer:
probability of getting I letter word =1/3
Three stores are selling the same brand of soda for different prices. Which stores has the better price? Store x / 4 for $2.48 Store Y / 5 for $3.00 Store Z:\$0.62 for 1 can
Answer:
store y has the best price
Step-by-step explanation:
store x you would pay .62 for each soda
store z you would pay .62 for one soda
and store y you would pay .60 for each soda so you would want to pick the one with the lowest price on each and you would get more for a lower amount of money.

does anyone know the answer??
Answer:
rational
Step-by-step explanation:
Any rational number can be expressed in the form
[tex]\frac{a}{b}[/tex] ← where a and b are integers
Given
[tex]\sqrt{4}[/tex] = - 2 or + 2
Since - 2 = [tex]\frac{-2}{1}[/tex] and 2 = [tex]\frac{2}{1}[/tex] ← both in rational form, then
[tex]\sqrt{4}[/tex] is rational

Davindra made a paper box that is 8 in. Long, 5 in. Wide, and 1 in. High. It is shaped like a rectangular prism. What is the surface area of the box? *
Answer:
106 in²
Step-by-step explanation:
Given that :
Davindra made a paper box that is 8 in. Long, 5 in. Wide, and 1 in. High.
Using the relation :
SA=2lw+2lh+2hw
Surface area :
2(lw + lh + hw)
l = 8 ; w = 5 ; h = 1
Surface area :
2(8*5 + 8*1 + 1*5)
Surface area :
2(40 + 8 + 5)
= 2(53)
= 106 in²
