Seth's first mistake was made in (blank)

Step 1, Step 2, Step 3, Step 4, or Step 5

where he (blank)

Factored 16 out of the second term instead of 4
Did not apply the properties of exponents correctly
Factored 2 out of the first term instead of 4
Did not write the expression as division correctly

Answer:

76 feet.

Step-by-step explanation:

The side of the pool = square root of 121 = 11 feet.

With the deck the length of 1 side  will be 11 + 2 *4 = 19 feet.

There are 4 sides in the outside perimeter so the answer:

= 4 * 19 = 76 feet.

Answer:

4.093%

Step-by-step explanation:

Here, we want to calculate the proportion of Newyork commutes that are less than 26 minutes

We start by calculating the z-score

z = (x - mean)/SD

here;

x = 26

mean = 38.5 minutes

SD = 7.2 minutes

Thus, we have;

z = (26-38.5)/7.2

z = -1.74

We proceed to use the standard normal distribution table to get the probability of P(x < -1.74)

That will be 0.04093

So the proportion will be this in %

That will be 4.093%

Answer:

1/2

Step-by-step explanation:

Pick to easy to read points on the line: (-4, 0) and (0, 2)

Start at (-4, 0). To go to (0, 2), you go 2 units up. That is a rise of 2.

Then you go 4 units right. that is a run of 4.

slope = rise/run = 2/4 = 1/2

Answer: 1/2

Answer:

The value is [tex]P(X < 13000) =0.054799[/tex]

Step-by-step explanation:

From the question we are told that

  The number of hours considered  is  [tex]x= 13000 \ hours[/tex]

   The population mean is [tex]\mu = 15000\ hours[/tex]

   The standard deviation is  [tex]\sigma = 1250\ hours[/tex]

Generally the the probability that a motor will have to be replaced free of charge is mathematically represented as

   [tex]P(X < 13000) = P(\frac{ X - \mu }{\sigma } < \frac{13000 - 15000}{1250} )[/tex]

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

     [tex]P(X < 13000) = P(Z<-1.6 )[/tex]

From the z table the probability of  (Z<-1.6 ) is

     [tex]P(Z<-1.6 ) = 0.054799[/tex]

So

    [tex]P(X < 13000) =0.054799[/tex]

g(x)={47,38,14,2,-16,-49}

Step-by-step explanation:

f(-17)=-3*-17-4=51-4=47

f(-14)=-3*-14-4=42-4=38

f(-6)=-3*-6-4=18-4=14

f(-2)=-3*-2-4=6-4=2

f(4)=-3*4-4=-12-4=-16

f(15)=-3*15-4=-45-4=-49

Answer:

Step-by-step explanation:

Let's call A the longest side. The others triangle sides are B and C.

We know that B = (1/4)*A  and C = A - 8

The triangle's perimeter is: A + B + C = 118

Substituting the values of sides B and C, we have:

A + (1/4)A + (A-8) = 118

Adding common terms:   (2 + 1/4)A = 118 + 8

                                     (9/4)A = 126    then,  A = 56 feet

                                     B = (1/4)A = 14 ft

                                     C = A - 8 = 48 feet

I hope it works for you

Answer:

3.20

Step-by-step explanation:

Answer:

(a) 9800π cm²/s

(b) 39200π cm²/s

(c) 58800π cm²/s

Step-by-step explanation:

As we know,

The area of circle is:

[tex]A= \pi r^2[/tex]

[tex]\frac{dA}{dt}=2 \pi r\frac{dr}{dt}[/tex]

The given value is:

[tex]\frac{dr}{dt} =70 \ cm/s[/tex]

Now,

(a)

After 1 second,

r = 70×1

 = 70 cm

⇒  [tex]\frac{dA}{dt}=2\pi(70)\times (70)[/tex]

          [tex]=9800 \pi \ cm^2/s[/tex]

(b)

After 2 second,

r = 70×4

 = 280 cm

⇒  [tex]\frac{dA}{dt}=2\pi \ (280)\times (70)[/tex]

          [tex]39200\pi \ cm^2/s[/tex]

(c)

After 6 seconds,

r = 70×6

 = 420 cm

⇒  [tex]\frac{dA}{dt}=2\pi \ (420)\times (70)[/tex]

          [tex]58800\pi \ cm^2/s[/tex]

The rate will be:

(a) 9800 π cm²/s

(b) 39200 π cm²/s

(c) 58800 π cm²/s

A circle seems to be a closed object or structure generated by tracing a point that travels together in plane at quite a constant distances from either a specific location.

According to the question,

Speed, [tex]\frac{dr}{dt}[/tex] = 70 cm/s

We know,

The area of circle:

→ A = πr²

  [tex]\frac{dA}{dt}[/tex] = 2πr[tex]\frac{dr}{dt}[/tex]

(a) After 1 s, the rate be:

r = 70 × 1

  = 70 cm

[tex]\frac{dA}{dt}[/tex] = 2π(70) × 70

    = 9800 π cm²/s

(b) After 2 s, the rate be:

r = 70 × 4

 = 280 cm

[tex]\frac{dA}{dt}[/tex] = 2π(280) × 70

    = 39200 π cm²/s

(c) After 6 s, the rate be:

r = 70 × 6

  = 420 cm

[tex]\frac{dA}{dt}[/tex] = 2π(420) × 70

    = 58800 π cm²/s

Thus the response above is correct.
