A dog is chained to a pole. If the dog can run within an area of 380 ft.², how long is the chain?
ty if you could help :)
Answer:
The chain is around 11 feet in length.
Step-by-step explanation:
Area of a circle = π × r²
380 ft² = π × r²
121 ft² = r²
11 ft = r
Solve for x: 2/7 (x-2) =4c
Answer:
x=14c+2
Step-by-step explanation:
[tex]\frac{2}{7} (x-2)=4c \\\frac{2}{7}x-\frac{4}{7} =4c\\\frac{2}{7}x=4c+\frac{4}{7}\\\frac{2}{7}x= \frac{28c+4}{7} \\2x=28c+4\\x=14c+2[/tex]

A store has clearance items that have been marked down by 45%. They are having a sale, advertising an additional 40% off clearance items. What percent of the original price do you end up paying?
Answer:
33%
Step-by-step explanation:
x = original price now take 45% off <=====means you pay 55% of original
.55 x is the new price now take 40% MORE off (leaving 60%)
.55x * .6 = .33 x

Drake and Evan are teammates on a high school swim team drake swim 312. 63 m during practice evan swim exactly 1/3 times farther than drake exactly how far did Evan swim?
Answer:
416.84 m
Step-by-step explanation:
First Step:
Multiple 312.63 by 1/3
312.63*1/3=104.21
Second Step:
Add 312.63 to 104.21
312.63+104.21=416.84
[tex]✤ \: \underline{ \underline{ \frak{Understanding~the~question : - }}} \\ \\ [/tex]
In this question, we have been provided that Evan swims 1/3 times farther than Drake, thus, the total distance covered by Evan will be equal to the sum of 312.63 m and the 1/3rd of 312.63 m. Thus, at first we will calculate the one third of the distance and then add them up to get our final answer.

What slope would make the lines
perpendicular?
y = 1/2x-1
y = [?]x - 1
Answer:
y = [-2]x - 1
Step-by-step explanation:
y = [-2]x - 1 will make the lines perpendicular.
Because the product of slopes of perpendicular lines is -1
-> 1/2*(-2) = -1

Can someone help with trigonometry? 12 points
Answer:
A° = 44.42°
Step-by-step explanation:
Soh Coh Toa
Soh: sin(theta) = Opp/Hyp
Coh: cos(theta) = Adj/Hyp
Toa: tan(theta) = Opp/Adj
We are using Coh: cos(theta) = Adj/Hyp because we need to find Angle A and that 5 is Adjacent and 7 is the Hypotenuse.
cos(A°) = 5/7
A° = cos^-1 (5/7)
A° ≈ 44.4153086
A° = 44.42°
what is (3x + 4)(5x − 2)
Answer:
15x² + 14x - 8
Step-by-step explanation:
Apply the distributive property by multiplying each term in (5x - 2) by each term in (3x + 4).
5x(3x) + (-2)(3x) + 5x(4) + (-2)(4)
= 15x² - 6x + 20x - 8
Combine like terms:
15x² + 14x - 8
(3x + 4)(5x − 2) is the factored form of 15x² + 14x - 8.

What is the difference between the 8th square number and the 4th square number?
Answer:
240
Step-by-step explanation:
The 8th square number is 2^8 = 256.
The 4th square number is 2^4 = 16.
Their difference is 256 - 16 = 240.
7) Mofor invests $3,101 in a savings account
with a fixed annual interest rate
compounded 2 times per year. After 6
years, the balance reaches $3. 932. 82.
What is the interest rate of the account?
Answer:
4%
Step-by-step explanation:
[tex]A = P(1+r/n)^{nt}[/tex]
A = final amount
P = initial amount
r = interest rate per time period
n = number of times compounded per time period
t = number of time period
A = 3932.82
r = what we want to find
n = 2
t = 6
[tex]A = P(1+r/n)^{nt}\\3932.82 = 3101(1+r/2)^{12}[/tex]
divide both sides by 3101 to isolate the exponent and its parts
[tex]3932.82/3101 = (1+r/2)^{12}[/tex]
put both sides to the power of (1/12) to help isolate the variable
[tex](3932.82/3101)^{1/12}= (1+r/2)[/tex]
subtract 1 from both sides to isolate the variable and its coefficient
[tex](3932.82/3101)^{1/12}-1= (r/2)[/tex]
multiply both sides by 2 to get r
[tex]((3932.82/3101)^{1/12}-1) * 2= r[/tex]
r ≈ 0.04 = 4%

Complete the point-slope equation of the line through (3,6) and (5,-8)
Answer:
y = - 7x + 17
Step-by-step explanation:
Given, (3,6) and (5,-8)
Equation of a straight line is y = mx + c
Here, y = -8, x = 5 and m = ?
m = [tex]\frac{Change in Y}{Change in X}[/tex]
m = [tex]\frac{-8 - 6}{5 - 3}[/tex]
m = - 7
Substituting x, y and m in y = mx + c we get,
- 8 = - 7(5) + c
c = 35 - 8
c = 17
The equation is y = - 7x + 17 (Answer).

Answer:
When parallel light rays exit a concave lens, they
✔ diverge
.
When parallel light rays exit a convex lens, they
✔ converge
.
Step-by-step explanation:
The requried, parallel light rays diverge when passing through a concave lens, and converge when passing through a convex lens.
What is reformation?Refraction is the bending of light as it passes from one medium to another medium of different optical densities, such as from air to water or from air to a glass lens.
When parallel light rays exit a concave lens, they diverge as the concave lens is thinner at the center and thicker at the edges. This shape causes the light rays to bend away from the optical axis and spread apart from each other, resulting in a virtual image that is smaller than the object.
On the other hand, when parallel light rays exit a convex lens, they converge towards a focal point as the lens is thicker at the center and thinner at the edges. This shape causes the light rays to bend towards the optical axis and meet at a focal point, resulting in a real image that is inverted and can be larger or smaller than the object depending on the distance of the object from the lens.
Therefore, the behavior of parallel light rays upon exiting concave and convex lenses is quite different due to their distinct shapes and curvatures, resulting in opposite effects on the direction of light rays and the formation of images.
