Easton practices the piano the same number of minutes each day. The relationship between the number of days, x, and the total number of minutes he practices, y, is represented by the graph below. A point (8, 200) is labeled below. Which statement about the graph is true?​

Answer:

The value of (gof)(9)=54

Step-by-step explanation:

We are given:

[tex]f(x) = -2x + 14\\g(x) = 2x^2 - 6x - 2[/tex]

We need to find (gof)(9).

To find (gof)(9) first we will find g(f(x)) and then put x=9

Finding g(f(x))

By putting value of f(x) into g(x) i.e

[tex]g(f(x))=2(-2x+14)^2-6(-2x+14)-2[/tex]

Now putting x=9

[tex]g(f(9))=2(-2(9)+14)^2-6(-2(9)+14)-2\\g(f(9))=2(-18+14)^2-6(-18+14)-2\\g(f(9))=2(-4)^2-6(-4)-2\\g(f(9))=2(16)+24-2\\g(f(9))=32+24-2\\g(f(9))=54[/tex]

so, the value of (gof)(9)=54

Answer 10.75

......................................

Answer:

10 and 3/4

Step-by-step explanation:

For the fractions, get a common denominator (bottom number): 1/2=2/4

So 2/4 plus 1/4 equals 3/4 and 5+5 equals ten.

10+3/4=10 3/4

Decimal form: 10.75

Answer:

155

Step-by-step explanation:

- because of the angle rules, (6x+1) = (2x+17)

- with this, you can now solve to get x = 4

- also because of the angle rules, y = 180 - (2x+17)

- replace the x with 4 and calculate and you'll get y = 155

Answer:

Step-by-step explanation:

Checkpoint A-> time being 1:00pm total miles driven being 120 and

checkpoint B-> time being 3:00pm and the total miles being 208

The distance between two checkpoint A  and B is 208 - 120 = 88 miles

Now the time between the two checkpoints = 3.00 - 1.00 = 2 hours

We need to find car speed between the checkpoints

We know Distance = speed * time

Speed = 44 miles per hour

Answer:

The answer is 1 miles

Answer:

that no. is 20

Step-by-step explanation:

let us take that certain no. as x

so

2/5. x +2=10

2x/5 = 10-2

2x = 8×5

x= 40/2

x= 20

Answer:

The correct option is  c

Step-by-step explanation:

From the question we are told that

   The mean is  [tex]\mu = 185.6 \ mm[/tex]

   The standard deviation is  [tex]\sigma = 12.7 \ mm[/tex]

   The sample size is  n = 10  

    Generally the standard error of the mean is mathematically represented as

      [tex]\sigma_{x} = \frac{\sigma}{\sqrt{n} }[/tex]

=>    [tex]\sigma_{x} = \frac{ 12.7}{\sqrt{ 10 } }[/tex]

=>    [tex]\sigma_{x} = 4.016[/tex]

Generally the probability that a random sample of size 10 from this population will have a mean less than than 180 is mathematically represented as

     [tex]P(X < 180 ) = P(\frac{ X - \mu }{\sigma_{x} } < \frac{180 - 185.6}{4.016} )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

    [tex]P(X < 180 ) = P(Z < - 1.394 )[/tex]

From the z table  the area under the normal curve to the left corresponding to    -1.394  is  

          [tex]P(X < 180 ) = P(Z < - 1.394 ) = 0.081659[/tex]

=>      [tex]P(X < 180 ) = 0.0823[/tex]

Answer:

the polynomial is: [tex]\mathbf{x^3-9x^2-4x+36=0}[/tex]

Step-by-step explanation:

We need to form a polynomial whose zeros are:

-2,2,9

We can write them as: x=-2, x=2 and x=9

x+2=0, x-2=0 , x-9=0

(x+2)(x-2)(x-9)=0

Now multiplying all terms:

[tex](x(x-2)+2(x-2))(x-9)=0\\(x^2-2x+2x-4)(x-9)=0\\(x^2-4)(x-9)=0\\x^2(x-9)-4(x-9)=0\\x^3-9x^2-4x+36=0[/tex]

So, the polynomial is: [tex]\mathbf{x^3-9x^2-4x+36=0}[/tex]

Answer:

d=2√10

Step-by-step explanation:

The distance between the two points will be given by:

d=√[(x-x1)^2+(y-y1)^2]

point z1=(3-2i) has the coordinates of (3,-2)

point z2=(5-8i) has the coordinates of (5,-8)

thus the distance between them will be:

d=√[(-8-(-2)²+(5-3)²)]

d=√[(-6)²+2²]

d=√(36+4)

d=√40

d=2√10

Answer:

3√2

Step-by-step explanation:

distance formula: d = √(a₁ - a₂)² + (b₁ - b₂)²

a = x, b = y

d = √(x₁ - x₂)² + (y₁ - y₂)²

Approximately 1.9 grams per cubic centimeter.

First you calculate the size of the cylinder in centimeters by taking the area of the base and multiplying it by the height, and then you divide the mass of the cylinder by the volume.
