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]

Step-by-step explanation:

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].

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]

Step-by-step explanation:

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

♪＼(*＾▽＾*)／＼(*＾▽＾*)／

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:

y=30

Step-by-step explanation:

Answer:

y=30

Step-by-step explanation:

y=4x-6

y=4(9)-6

y=36-6

y=30

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
