Answer:
Step-by-step explanation:
1). a(x) = -4x + 7 If x > 1
a(8) = -4(8) + 7
= -32 + 7
= -25
2). a(x) = 2x - x² If -6 < x ≤ 1
a(1) = 2(1) - 1²
= 2 - 1
= 1
3). a(x) = |x - 8| If x ≤ -6
a(-7) = |- 7 - 8|
= |-15|
= 15
4). a(x) = 2x - x² If -6 < x ≤ 1
a(-3) = 2(-3) - (-3)²
= -6 - 9
= -15
5). a(x) = 2x - x² If -6 < x ≤ 1
[tex]a(-\frac{1}{2})=2(-\frac{1}{2})-(-\frac{1}{2})^{2}[/tex]
= - 1 - [tex]\frac{1}{4}[/tex]
= [tex]-\frac{5}{4}[/tex]
6). a(x) = -4x + 7 If x > 1
[tex]a(\frac{9}{4})=-4(\frac{9}{4})+7[/tex]
= -9 + 7

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
Answers
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.

After how many months will the total cost for

Yoga Studio
Yoga Studio A
Membership 522.00
Monthly Fee $24.50
Membership 547.00
Monthly Fee $18.25
Answers
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.

Answers

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.

The lowest priced stereo system in the store sells for $800, The lowest priced stereo system in the store sells for 800 dollars, and the highest priced stereo system sells for $3000. and the highest priced stereo system sells for 3000 dollars. Which of the following is the maximum amount of $3000 systems on hand Which of the following is the maximum amount of 3000 dollar systems on hand if the current inventory totals $111,000?
The answer is 32, I need an explanation how to find the answer.
Answers
Explanation:
let H = number of expensive high price stereo
systems
let L = number of less expensive low price
stereo systems
H +L = 50 =
3,000H + 80OL = 110,000
H = 50 - L (now replace)
3,000 (50 - L) + 800 L = 110,00
150,000 - 3,000L + 800L = 110,000
150,000 - 110,000 = 3,000L - 800L =
40,000 = 2,2OOL
L = 40,000 / 2,200 = 18.18 = 18 lower priced = =
stereo systems H = 50 - 18 = 32 higher priced stereo systems
=
=
(3,000 x 32) + (800 x 18) = 96,000 + 14,400 = 110,400
Even though the answer is not exact, if you had 33 high cost stereo systems, your inventory's cost = $112,600 which is $1,600 off

Angle W measures 68 degrees more than angle F. Angles Wand
Fare supplementary. What is the measure of angle W?
Answers
Answer: The measure of angle W is 124°.
Step-by-step explanation:
Given: Angles W and F are supplementary.
We know that the sum of two supplementary angles is 180 degrees.
So, ∠W + ∠F = 180° (i)
As per given,
∠W = ∠F + 68° (ii)
Put value of ∠W from (ii) in (i)
∠F + 68°+∠F = 180°
⇒ 2 ∠F = 180°- 68°
⇒ 2 ∠F = 112°
⇒ ∠F = 56°
From (ii),
∠W = 56° + 68°
⇒ 124°
Hence, the measure of angle W is 124°.

Any hypothesis that an analyst has accepted to be true and which forms the basis of an assessment is a: ______
Answers
Answer:
The correct answer is the alternate hypothesis.
Step-by-step explanation:
A null hypothesis is a sort of hypothesis used in statistics that intends that no statistical significance exists in a set of given observations.
It is a hypothesis of no difference.
It is typically the hypothesis a scientist or experimenter will attempt to refute or discard. It is denoted by H₀.
For instance, H₀: µ = µ₀, where µ₀ is some null value or some claimed value.
Whereas, the alternate hypothesis is the contradicting statement to the null hypothesis.
The alternate hypothesis describes direction of the hypothesis test, i.e. if the test is left tailed, right tailed or two tailed.
It is also known as the research hypothesis and is denoted by Hₐ.
Thus, the correct answer is the alternate hypothesis.
