For the function f(x) = -3sin(x) + 2, the distance between the maximum and minimum values is 6. Which statement must be true about this function? HINT: It's not B.
A. The amplitude is 3.
B. The midline is y = 3.
C. The period of the function is 3pi.
D. The range is [-3, 3].
Answer: A. The amplitude is 3.
Step-by-step explanation:
Given function : [tex]f(x) = -3sin(x) + 2[/tex]
Period of a sine function is [tex]2\pi.[/tex]
Since [tex]-1\leq \sin x \leq 1[/tex]
[tex]\Rightarrow\ -3\leq -3\sin x\leq 3\\\\\Rightarrow\ -3+2\leq -3\sin x+2\leq 3+2\\\\\Rightarrow\ -1\leq -3\sin x+2\leq 5[/tex]
i.e. Range is [-1,5]
Amplitude = 3 [coefficient of sin x]
Only option A. is correct.
f(2)=−14 and g(2)=13 Find (f+g)(2).
Answer: The value of (f+g)(2) = -1
Step-by-step explanation:
Given: f(2)=-14 and g(2)=13
To find: (f+g)(2)
Addition of two functions:
(f+g)(x) = f(x)+g(x)
Then, (f+g)(2) = f(2)+g(2)
(f+g)(2) = -14+13 [given]
(f+g)(2) = -1
Therefore , the value of (f+g)(2) = -1
When a certain basketball player takes his first shot in a game he succeeds with prob. 1/3. If he misses his first shot, he loses confidence and his second shot will go with prob. 1/4. If he misses his first 2 shots, his third shot will go with pro. 1/5. If he misses his first 3 shots, his fourth shot will go with prob. 1/6. If he misses his first 4 shots, the coach will remove hom from the game. Assume that the player keeps shooting until he succeeds or he is removed from the game. Let X denote the number of shots he misses until his first success or until he is removed from the game.
Required:
a. Compute the p.m.f. of X
b. Compute E[X]
Answer:
X : ____ 0 ____1 ____ 2 ____ 3 ____ 4
P(x) : _ 0.333_0.167 _0.100_0.067__0.333
E(X) = 1.9
Step-by-step explanation:
From the question above:
X ; number of misses
For :
X = 0 ; P(X = 0) = 1/3 = 0.333
X = 1 ; misses first ; succeeds on second
P(X = 1) = 2/3 * 1/4 = 2/12 = 1/6 = 0.167
X = 2 ; misses first, misses second, succeeds on third
P(X = 2) = 2/3 * (1 - 1/4) * 1/5 = 2/3*3/4*1/5 = 6/60 = 1/10 = 0.10
X = 3 :misses first, misses second, misses third succeeds on fourth
P(X = 3) = 2/3 * 3/4 * (1 - 1/5) * 1/6 = 2/3*3/4*4/5*1/6 = 24/360 = 0.067
X= 4
P(X =4) = 2/3 * 3/4 * 4/5 * 5/6 = 120/ 360 = 1/3 = 0.333
X : ____ 0 ____1 ____ 2 ____ 3 ____ 4
P(x) : _ 0.333_0.167 _0.100_0.067__0.333
E(X) :
Σx*p(x) = (0*0.333) + (1*0.167) + (2*0.100) + (3*0.067) + (4*0.333)
0 + 0.167 + 0.2 + 0.201 + 1.332
= 1.9

Mr.Millar's garden is in the shape of a trapezoid shown below. what is the area of his garden
Answer:
[tex]Area = 12.5m^2[/tex]
Step-by-step explanation:
Given
See attachment
Required
Determine the area
The area is calculated using:
[tex]Area = \frac{1}{2} * (Sum\ of\ parallel\ sides) * Height[/tex]
From the attached image:
The parallel sides are 4m and 6m respectively while the height is 2,5m
So, the area is:
[tex]Area = \frac{1}{2} * (4m + 6m) * 2.5m[/tex]
[tex]Area = \frac{1}{2} * 10m * 2.5m[/tex]
[tex]Area = 5m * 2.5m[/tex]
[tex]Area = 12.5m^2[/tex]

Paul built a triangular garden in his backyard, which is enclosed by a rectangular fence.
How much of the backyard is not covered by the garden?
452 m2
476 m2
524 m2
548 m2
whats the answer plz
Answer:
[tex]Area = 476m^2[/tex]
Step-by-step explanation:
Given
See attachment
Required
The uncovered area
First, calculate the area of the rectangle
[tex]Area = Length * Width[/tex]
From the attachment
[tex]Length = 25m[/tex] and [tex]Width = 20m[/tex]
So:
[tex]Area = 25m * 20m[/tex]
[tex]Area = 500m^2[/tex]
The area of the triangle is:
[tex]Area = \frac{1}{2} * Base * Height[/tex]
From the attachment
[tex]Base = 8m[/tex]
[tex]Height = 6m[/tex]
So:
[tex]Area = \frac{1}{2} * 8m * 6m[/tex]
[tex]Area = \frac{1}{2} * 48m^2[/tex]
[tex]Area = 24m^2[/tex]
The uncovered area is:
[tex]Area = 500m^2 - 24m^2[/tex]
[tex]Area = 476m^2[/tex]

Which value is nearest to 8? Show thinking in the space provided.
7.511 155/20 8.3%
Answer:
155/20
Step-by-step explanation:
155/20 in decimal form is 7.75, which is only 0.25 off of 8
7.511 is 0.489 off of 8
8.3% is technically not anywhere near 8 because a percentage needs to be a percentage of something in order to make sense.
