HELP!!!!!!!

Functions f(x) and g(x) are shown:

f(x) = x2 g(x) = x2 + 8x + 16

In which direction and by how many units should f(x) be shifted to match g(x)?

A. Left by 4 units

B. Right by 4 units

C. Left by 8 units

D. Right by 8 units

**Answer:**

Option A, Left by 4 units

**Step-by-step explanation:**

Step 1: Convert g(x) to a function square

We currently have g(x) in this order: [tex]ax^2 + bx + c[/tex]

However, we want g(x) to be in this order: [tex](ax + c)^{2}[/tex]

The first thing we have to do is to** factor it out:**

[tex]g(x)=x^{2}+8x+16[/tex]

[tex]g(x) = (x + 4)(x + 4)[/tex]

[tex]g(x) = (x+4)^{2}[/tex]

Step 2: Now we can see which way we need to move it

The original form is: [tex]f(x) = (ax - b)^{2}[/tex]

Since the - has changed to a +, that means that we moved -4 spaces down the x-axis. This means that we move left by 4 units.

**Answer: **Option A, Left by 4 units

*Look at the graphs below to make sure:*

**Answer:**

*A.) Left By 4 Units*

**Step-by-step explanation:**

Functions f(x) and g(x) are shown below: f(x) = x2 g(x) = x2 + 8x + 16

The direction in which and by how many units the f(x) should be shifted to obtain the g(x) is given by as follows.

Given,

f(x) = x²

g(x) = x² + 8x + 16

we have to consider, the dependent term while selecting the direction.

Therefore, except x², only x term is dependent term.

In g(x), the x term is given by 8.

Therefore, we need to shift the f(x) left by 4 units.

*
*

*Therefore, option A is correct.*

csc Θ of cos Θ = -3/5 180° ≤ Θ ≤ 270°

csc =

9514 1404 393

**Answer:**

**Step-by-step explanation:**

The relevant relations are ...

sec = ±√(tan² +1)

cos = 1/sec

csc = 1/sin = ±1/√(1 -cos²)

Sine and Cosecant are positive in quadrants I and II. Cosine and Secant are positive in quadrants I and IV.

__

1. sec(θ) = -√((-2)² +1) = -√5

2. cos(θ) = 1/sec(θ) = 1/(5/3) = 3/5

3. csc(θ) = -1/√(1 -(-3/5)²) = -√(16/25) = -4/5

PLEASE HELP! The AHS football team did a weigh-in at the start of training camp. The weights of the players were distributed normally with a mean of 98kg and a standard deviation of 6kg. What percentage of players are under 86kg?

**Answer:**

2.28% of players are under 86kg

**Step-by-step explanation:**

**Normal Probability Distribution:**

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

**The weights of the players were distributed normally with a mean of 98kg and a standard deviation of 6kg.**

This means that [tex]\mu = 98, \sigma = 6[/tex]

**What percentage of players are under 86kg?**

The proportion is the pvalue of Z when X = 86. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{86 - 98}{6}[/tex]

[tex]Z = -2[/tex]

[tex]Z = -2[/tex] has a pvalue of 0.0228

0.0228*100% = 2.28%

2.28% of players are under 86kg

You have a bag of 10 marbles. Three of them are red, five are blue, and two are green. What is the probability of NOT picking a green marble out of the bag randomly?

**Answer:**

hey there

The answer is 7/10

this is true because we have two green marbles and five blue

2+5=7

**Step-by-step explanation:**

**Answer:**

20% or 2/10

**Step-by-step explanation:**

10 marbles in total. We want to find the probability of not picking a green marble. 10marbles-3red-5blue=2marbles left.

So the probability of picking a green marble is 2/10 or 20%

A particle moves along a horizontal line so that its position at time t, t ≥ 0, is given by

s(t) = 40 + te^−t/20.

Find the minimum velocity of the particle for 0 ≤ t ≤ 100.

**Answer:**

The minimum velocity of the particle = [tex]-e^{-2 }[/tex] units

**Step-by-step explanation:**

**Given -** A particle moves along a horizontal line so that its position at time t,

t ≥ 0, is given by s(t) = 40 + te^−t/20.

**To find -** Find the minimum velocity of the particle for 0 ≤ t ≤ 100.

**Proof -**

Velocity, v(t) = [tex]\frac{d}{dt}(40 + te^{-\frac{t}{20} } )[/tex]

Now,

[tex]\frac{d}{dt}(40 + te^{-\frac{t}{20} } )[/tex] = [tex]\frac{d}{dt}(40 ) + \frac{d}{dt}(te^{-\frac{t}{20} } )[/tex]

= 0 + [tex]t\frac{d}{dt}(e^{-\frac{t}{20} } ) + e^{-\frac{t}{20} }\frac{d}{dt}(t )[/tex]

= [tex]t(-\frac{1}{20} )e^{-\frac{t}{20} } + e^{-\frac{t}{20} }[/tex]

⇒v(t) = [tex]-\frac{t}{20}e^{-\frac{t}{20} } + e^{-\frac{t}{20} }[/tex]

Now,

For minimum velocity, Put [tex]\frac{d}{dt}(v(t)) = 0[/tex]

Now,

[tex]\frac{d}{dt}[v(t)] = \frac{d}{dt} [ -\frac{t}{20}e^{-\frac{t}{20} } + e^{-\frac{t}{20} } ][/tex]

= [tex]-\frac{2}{20} e^{-\frac{t}{20} } + \frac{t}{400} e^{-\frac{t}{20} }[/tex]

Now,

Put [tex]\frac{d}{dt}(v(t)) = 0[/tex], we get

[tex]-\frac{2}{20} = - \frac{t}{400}[/tex]

⇒t = 40

Now,

Check that the point is minimum or maximum

Calculate [tex]\frac{d^{2} }{dt^{2} } [v(t)][/tex]

Now,

[tex]\frac{d^{2} }{dt^{2} } [v(t)][/tex] = [tex]\frac{d}{dt} [ -\frac{2}{20} e^{-\frac{t}{20} } + \frac{t}{400} e^{-\frac{t}{20} }][/tex]

= [tex]\frac{1}{400}e^{- \frac{t}{20} } [ 3 - \frac{t}{20}][/tex]

⇒[tex]\frac{d^{2} }{dt^{2} } [v(t)][/tex] = [tex]\frac{1}{400}e^{- \frac{t}{20} } [ 3 - \frac{t}{20}][/tex] > 0

∴ we get

t = 40 is point of minimum

So,

The minimum velocity be

v(40) = [tex]-\frac{40}{20}e^{-\frac{40}{20} } + e^{-\frac{40}{20} }[/tex]

= [tex]-2e^{-2 } + e^{-2 }[/tex]

= [tex]-e^{-2 }[/tex]

⇒v(40) = [tex]-e^{-2 }[/tex] units

∴ we get

The minimum velocity of the particle = [tex]-e^{-2 }[/tex] units

C.

**Step-by-step explanation:**

**Given**

[tex]A =(x_1,y_1)[/tex]

[tex]B =(x_2,y_2)[/tex]

[tex]C =(x_3,y_3)[/tex]

[tex]D =(x_4,y_4)[/tex]

**Required:**

Which condition proves that AB is perpendicular to CD

First, calculate the slopes of both.

**For AB**

[tex]m_1 = \frac{y_2 -y_1}{x_2 - x_1}[/tex]

**For CD**

[tex]m_2 = \frac{y_4 -y_3}{x_4 - x_2}[/tex]

**The condition of perpendicularity is:**

[tex]m_1 * m_2 = -1[/tex]

**Substitute values for m1 and m2**

[tex]\frac{y_2 -y_1}{x_2 - x_1} * \frac{y_4 -y_3}{x_4 - x_2} = -1[/tex]

**Option (c) is correct**

Through part of the 2017-18 National Basketball Association (NBA) season,

two players had these statistics for the number of points they scored.

Anthony Davis Kevin Durant

Points per game (mean): 25.9 26.0

Mean average deviation: 6.6

Based on these data, which statement is true?

4.3

A. On average, Kevin Durant scored many more points. The number

of points Durant scored also varied more.

B. On average, Anthony Davis scored many more points. The number

of points Davis scored also varied more.

C. On average, the two players scored about the same number of

points. The number of points Davis scored varied more.

D. On average, the two players scored about the same number of

points. The variation in the number of points scored was also

about the same

C is your answer.

25.9 is about the same as 26.

Mean average deviation is an average of how far away from the mean number of points scored. So a smaller MAD means the player was more consistent

/had less variation.

What is the value of y in the following equation? -10y + 4(3y – 8) = -64

**Answer:**

y=-16

**Step-by-step explanation:**

**Answer:**

y = -16

**Step-by-step explanation:**

−10y+4(3y−8)=−64

Step 1: Simplify both sides of the equation.

−10y+4(3y−8)=−64

−10y+(4)(3y)+(4)(−8)=−64(Distribute)

−10y+12y+−32=−64

(−10y+12y)+(−32)=−64(Combine Like Terms)

2y+−32=−64

2y−32=−64

Step 2: Add 32 to both sides.

2y−32+32=−64+32

2y=−32

A university class has 29 students: 14 are accounting majors, 9 are business majors, and 6 are history majors. The professor is planning to select two of the students for a demonstration. The first student will be selected at random, and then the second student will be selected at random from the remaining students. What is the probability that the first student selected is an accounting major and the second student is a history major

**Answer:**

0.1034 = 10.34% probability that the first student selected is an accounting major and the second student is a history major

**Step-by-step explanation:**

A **probability **is the number of desired outcomes divided by the number of total outcomes.

**In this question:**

14 account majors from a set of 29 students.

Then, 6 history majors from a set of 29 - 1 = 28 students.

So

[tex]p = \frac{14}{29}*\frac{6}{28} = \frac{14*6}{29*28} = 0.1034[/tex]

0.1034 = 10.34% probability that the first student selected is an accounting major and the second student is a history major
