Answer:
95°
Step-by-step explanation:
since sum of interior angles add upto 180°
2x+3x+5+25°=180°
substituting you get
5x+30°=180°
5x=180-30
5x=150°
therefore divide
you will get x=30°
angle at v =30×3+5
=95°
What survival rate in the 10th year would make the average of loss over the 10 year period equal to 38.0%
Answer: 63%
Step-by-step explanation:
First step
Find the 10th year rate of loss that will make the average of loss over the 10 years to equal 38.0%.
Assume this rate is x;
[tex]\frac{(36.2 + 29.0 + 46.2 + 37.5 + 40.9 + 40.0 + 32.6 + 40.5 + 40.1 + x)}{10} = 38.0\\\\\frac{343 + x}{10} = 38\\\\x = 380 - 343\\\\x = 37[/tex]
x = 37%
Second step - Survival rate
The survival rate is calculated by;
= 1 - rate of loss
= 1 - 37%
= 63%

14. Veronica is choosing between two health clubs.
After how many months will the total cost for
each health club be the same?
Yoga Studio
Yoga Studio A
Membership 522.00
Monthly Fee $24.50
Membership 547.00
Monthly Fee $18.25
Answer:
The total cost for each health club would be the same after 4 months.
Step-by-step explanation:
Answer:
The total cost for each health club will be the same after 4 months.
Step-by-step explanation:
For studio A:
Membership fee = $22.00
Monthly Fee = $24.50
The equation for studio A:
A = 22 + 24.5xFor studio B:
Membership fee = $47.00
Monthly Fee = $18.25
The equation for studio B:
B = 47 + 18.25xLet 'x' be the month of membership
We must have to find the value of month or 'x' for which the total cost at each health studio is the same.
i.e. when A = B
Hence, the expression will be
A = B
22 + 24.5x = 47 + 18.25x
Please note that if we put x=4, the L.H.S and R.H.S of the equations become the same
i.e.
22 + 24.5(4) = 47 + 18.25(4)
22 + 98 = 47 + 73
120 = 120
so, at x=4 the equations become the same.
Therefore, the total cost for each health club would be the same after 4 months.

Use binomial expansion to solve each exercise. (a) Find the coefficient of xy19 in (3x − 2y) 20.(b) Give a formula for the coefficient of x k in (x+1/ x) n .
9514 1404 393
Answer:
(a) -29,884,416
(b) C(n,(n -k)/2) . . . where C(n,k) = n!/(k!(n-k)!) and k ∈ ℕ
Step-by-step explanation:
(a) The coefficient of the k-th term of the expansion is ...
C(20,k)(3x)^(20-k)(-2y)^k
For k=19, this is ...
19(3x)(-2y)^19 = -29,884,416xy^19
The coefficient of the term is -29,884,416.
__
(b) The p-th term of the expansion of (x +1/x)^n is ...
C(n,p)(x^(n-p)(1/x)^p = C(n,p)(x^(n-2p))
For some exponent k of x, the value of p will be ...
k = n -2p
p = (n -k)/2
Then the coefficient of x^k will be C(n, (n-k)/2), where C(n, x) = n!/(x!(n-x)!).
You will notice that there will only be a term x^k for k having the same parity as n.
A company makes a very durable product. The company sells 20,000 products in the first year but will be diminishing sales due to the product's durability, so each year it can expect to sell only 75% of the quantity it will have sold the year before. How many products can the company expect to eventually sell?
a. 26,667 products
b. 40,000 products
c. 80,000 products
d. 35,000 products
Answer:
c. 80,000 products
Step-by-step explanation:
Year 1 = 20000
20000 * 0.75 = 15000
Year 2 = 15000
15000 * 0.75 = 11250
Year 3 = 11250
11250 * 0.75 = 8437.5
Etc.
20000 + 15000+ 11250 + 8437.5 = 54687.5
If you continue this, you'll eventually reach 80000
80000 products can the company expect to eventually sell.
What is Sequence?Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.
A geometric sequence is a sequence in which each term is found by multiplying the preceding term by the same value.
Given,
The company sells 20,000 products in the first year
a=20000
each year it can expect to sell only 75% of the quantity it will have sold the year before
r=75/100=0.75
Sum of Geometric sequence S=a/1-r
S=20000/1-0.75
S=20000/0.25
S=80000
Hence, 80000 products can the company expect to eventually sell.

On a blueprint, the diagram of a building has a height of 23 cm.
The height of the building is x times the height of the diagram.
Which equation represents the height, h, of the building?
A h = 23+x
B X = 23=h
C h = 23x
D
X = 23h
Answer:
C h = 23x
Step-by-step explanation:
The height is h, so we want h = something.
The blueprint height is 23 cm.
The real height is x times 23 cm, so it is 23x.
h = 23x
