What is the common difference d of the sequence nine -8 -25 -42 -59
Answer:
The common difference d in the given sequence is -17
Step-by-step explanation:
We need to find the common difference d of the following sequence 9 -8 -25 -42 -59
We have a₁ = 9
and a₂ = -8
The formula used is: [tex]a_n=a_1+(n-1)d[/tex]
By putting values we can find the value of d
We have n=2, a₂ = -8, a₁ = 9 and we need to find d
[tex]a_n=a_1+(n-1)d\\a_2=a_1+(2-1)d\\-8=9+d\\d=-8-9\\d=-17[/tex]
So, the common difference d in the given sequence is -17

I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!
Answer:
345
Step-by-step explanation:
10 percent means to divide by 10. 10 percent of 460 is 46. 5 percent is therefore half of that. you know 10 percent of 460 is 46, so 70 percent would be multiplying that by 7. 46 times 7 is 322. add 5 percent to find 75percent. 5 percent of 460 is 23. 322+23 is 345:)
State what additional information is required in order to know that the triangles are congruent for the for the reason given
Answer/Step-by-step explanation:
1. Only one side and an included angle is known. To prove that both triangles are congruent by the SAS Congruence Theorem, an additional information such as a corresponding second side (KJ, and HJ) must be given to be equal to each other.
KJ = HJ
2. Additional information such as a second corresponding angle (angles C and W must be known to prove both triangles are congruent by SAS.
<C = <W
3. Additional information needed is a second corresponding angles must be known to prove the AAS.
4. Additional information needed is the corresponding angles, R and L, which should be equal to prove the ASA.
<R = L
5. Additional information needed: <C = <H
6. Additional information needed: equal hypotenuse lengths of both traingles.
What is the slope of the line that passes through the points (3, 4)(3,4) and (0, -2) ?(0,−2)? Write your answer in simplest form.
9514 1404 393
Answer:
2
Step-by-step explanation:
The slope formula is useful for the purpose.
m = (y2 -y1)/(x2 -x1)
m = (-2 -4)/(0 -3) = -6/-3
m = 2
The slope of the line is 2.
4 cups water for every 1/2 cup soap. How much water would be needed if I have 2/3 cup soap
Answer:

a fisherman floats 58ft. out from the shore. he notices a bird in the sky directly above the shoreline. if the angle of elevation from the fisherman to the bird is 23 degrees, how far is the fisherman from the bird.
Answer:
63 ft
Step-by-step explanation:
We solve this question using Trigonometric function of Cosine
cos θ = Adjacent/Hypotenuse
From the question:
θ = 23°
Adjacent = The distance of the fisherman from shore = 58 ft
Hypotenuse = The distance of the fisherman from the bird = x ft
Hence:
Cos 23 = 58/x
Cross Multiply
Cos 23 × x = 58
x = 58/Cos 23
x = 63.00890189 ft
Approximately = 63 ft
The distance of the fisherman from the bird is 63 ft
1) Ms. Kitts works at a music store. Last week she sold 6 more than 3 times the number of CDs that she sold this week. Ms. Kitts sold a total of 108 CDs over the 2 weeks. Which system of equations can be used to find L, the number of CDs she sold last week, and t, the number of CDs she sold this week?
Answer:
L = 3t + 6
108 = L + t
Step-by-step explanation:
first, define the variables:
L = # of CDs sold last week
t = # of CDs sold this week
then, let's write what the words of problem tells us in numbers:
"Last week (L), she sold 6 more (+ 6) than 3 times the number of CDs she sold this week (3t)
L = 3t + 6
"She sold a total of 108 CDs over 2 weeks (L + t)
108 = L + t

why do planets orbit
Answer:
Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.
