rectangle will have length 3n+ 6 and height 2n−1 inches, while the square will have side length n+ 2inches. Find the perimeter and area of your creation. Give your answers in fully factored form and includeunits. As part of your solution, redraw the below picture labelling all the sides.

Answer:

[g+2/3g-1] ÷ [g^2+2g/6g+2]

g+2/3g-1 × 6g+2/g^2+2g

g+2/3g-1 × 2(3g +1)/g(g+2)

1/ 3g-1 × 2(3g+1)/g

2(3g +1)÷ g(3g-1)

6g+2 ÷[3g^2-g]

the answer is 1 and 4

Answer:

The probability of completing the exam in one hour or less is 0.0228.

Step-by-step explanation:

Given: Mean = 80

Standard deviation = 10

To find: The probability of completing the exam in one hour or less.

We have, [tex]\mu=80[/tex] and [tex]\sigma=10[/tex].

Now, the z-value is the sample mean decreased by the population mean divided by the standard deviation.

[tex]z=\frac{\bar{x}-\mu}{\sigma}[/tex]

⇒[tex]z=\frac{60-80}{10}[/tex]

⇒[tex]z=-2[/tex]

Now, [tex]z=\frac{\bar{x}-\mu}{\sigma}[/tex]

⇒[tex]z=\frac{75-80}{10}[/tex]

⇒[tex]z=-0.5[/tex]

Again, [tex]z=\frac{\bar{x}-\mu}{\sigma}[/tex]

⇒[tex]z=\frac{90-80}{10}[/tex]

⇒[tex]z=1[/tex]

Using appropriate appendix table, we get [tex]P(z<-2)=0.0228[/tex].

This question is incomplete, the complete question is;

Katie Ledecky swims the length of a 50m Olympic size pool in 25 seconds and swims the return trip to the starting position in 26 seconds. What are her average velocities during:

a) The first half of the swim?

b) The second half of the swim?

Answer:

a) her average velocities during the first half = 2 m/s

b) her average velocities during the second half = 1.923 m/s

Step-by-step explanation:

Given that;

displacement = 50 m

time taken t = 25 secs

a)

average velocity = displacement / time taken = 50 / 25 = 2 m/s

Therefore her average velocities during the first half = 2 m/s

b)

In the second half;

displacement = 50 m

time taken t = 26 secs

average velocity = displacement / time taken = 50 / 26 = 1.923 m/s

Therefore her average velocities during the second half = 1.923 m/s

The balance would be $124 annually, $62 every 6 months, $31 every 3 months, $10.33 every month, and $0.34 every day.

Given that a person charges $100 to a credit card with a 24% nominal annual interest rate, assuming no other charges or payments are made, to find the balance on the card, in dollars, after 1 year for interest calculated at each time interval, the following calculation must be performed:

Therefore, the balance would be $124 annually, $62 every 6 months, $31 every 3 months, $10.33 every month, and $0.34 every day.

Answer:

y=0.02(5)^x

Step-by-step explanation:

Here,

a+b=20

ab=50

we know that,

[tex]\tt{ (a+b)^2=a^2+b^2+2ab }[/tex] ⠀

According to the question,

[tex]\tt{(20)^2=a^2+b^2+2×50 }[/tex] ⠀

[tex]\tt{ 400=a^2+b^2+100 }[/tex] ⠀

[tex]\tt{ a^2+b^2=400-100 }[/tex] ⠀

[tex]\tt{a^2+b^2=300 }[/tex] ⠀

Answer:

      a² + b² = 300

Step-by-step explanation:

a + b = 20  ; ab = 50

(a +b)² = a²+ b² + 2ab

a² + b² + 2ab = (a + b)²

a² + b² + 2*50 = (20)²

a² + b² + 100 = 400

         a² + b² = 400 - 100

        a² + b² = 300

Answer:

12.76

Step-by-step explanation:

This is much easier to solve if you draw it out on a graph. The perimeter is the sum of all the sides. I used the Pythagorean theorem to find the hypotenuse.

[tex] {a}^{2} + {b}^{2} = {c}^{2} \\ c = \sqrt{ {a}^{2} + {b}^{2} } [/tex]

[tex]dc = \sqrt{ {3}^{2} + {1}^{2} } = \sqrt{10} \\ cf = 1 \\ fe = \sqrt{ {4}^{2} + {2}^{2} } = \sqrt{20} \\ de = \sqrt{ {1}^{2} + {4}^{2} } = \sqrt{17} \\ \sqrt{10} + 1 + \sqrt{20} + \sqrt{17} = 12.76[/tex]

Answer:

0.51cm/s

Step-by-step explanation:

Area of a circle A = πr²

r is the radius

Rate of change of area is expressed as;

dA/dt = dA/dr • dr/dt

dA/dr = 2πr

radius r = 77cm

dA/dt = 79cm²

Get dr/dt

Substitute the given values into the formula

79 = 2π(77)•dr/dt

79 = 154dr/dt

dr/dt = 79/154

dr/dt = 0.51cm/s

Hence the rate of change of the radius is 0.51cm/s

Answer: Subtract 3 from each side

Step-by-step explanation:

The goal of the problem is to isolate 3 on one side by itself. The only thing standing in our way is that pesky three. In order to get rid of it, and make y have the whole left side to themselves, we have to see what is three doing in the equation. Well, it is a positive three and it is being added to y. So, we want to do the opposite of what it is. Since it is a positive three, we are going to subtract three on both sides. It will zero itself out on the left side and move on over to the right side, giving y the entire left side of the equation.
