Step-by-step explanation:

-2 × -2 ÷ 1/2 =8

Carbon-14 will take 19,035 years to decay to 10 per cent.

A radioactive half-life refers to the amount of time it takes for half of the original isotope to decay.

An exponential decay can be described by the following formula:

[tex]N(t)=N_oe^{-\lambda t}[/tex]

Where:

No  = The quantity of the substance that will decay.

N(t) = The quantity that still remains and has not yet decayed after a time t

[tex]\lambda[/tex]    = The decay constant.

One important parameter related to radioactive decay is the half-life:

[tex]t_{1/2}=\dfrac{Ln(2)}{\lambda}[/tex]

If we know the value of the half-life, we can calculate the decay constant:

[tex]\lambda =\dfrac{ln(2)}{t_{1/2}}[/tex]

Carbon-14 has a half-life of 5,730 years, thus:

[tex]\lambda =\dfrac{ln(2)}{5730}[/tex]

[tex]\lambda[/tex] = 0.00012097

The equation of the remaining quantity of Carbon-14 is:

[tex]N(t)=N_oe^{-0.00012097t}[/tex]

We need to calculate the time required for the original amount to reach 10%, thus N(t)=0.10No

[tex]0.10N_o=-N_oe^{-0.00012097t}[/tex]

Simplifying:

[tex]0.10=e^{0.00012097t}[/tex]

Taking logarithms:

ln(0.10) = -0.00012097t

Solving for t:

[tex]t=\dfrac{Log0.10}{-0.00012097}[/tex]

t = 19035 years

Carbon-14 will take 19,035 years to decay to 10 per cent.

Answer:

the future value is $5,750.01

Step-by-step explanation:

The computation of the future value is shown below;

As we know that

Future value = Present value × (1 + rate of interest)^number of years

= $5,000 × (1 + 0.035 ÷ 12)^4 × 12

= $5,000 × (1 + 0.2916%)^48

= $5,750.01

Hence, the future value is $5,750.01

Answer:

m<KNL = 65°

m<MNL = 65°

Step-by-step explanation:

An angle bisector divides an angle into two equal parts.

Thus:

m<KNL = m<MNL

Substitute

5x + 10 = 6x - 1

Collect like terms

5x - 6x = -10 - 1

-x = -11

Divide both sides by -1

x = 11

✔️m<KNL = 5x + 10

Plug in the value of x

m<KNL = 5(11) + 10 = 55 + 10

m<KNL = 65°

✔️m<MNL = 6x - 1

Plug in the value of x

m<MNL = 6(11) - 1 = 66 - 1

m<MNL = 65°

Answer:

Step-by-step explanation:

area = (5x-3)² = (25x² - 30x + 9) cm²

Answer:

x = 66

Step-by-step explanation:

Emily's mistake is that part of the line is only x - 6, but she put 6x - 6

The first 6 shouldn't be there.

x - 6 = 72

x = 66

The actual correct answer is:

   x = 78

Step-by-step explanation:

Although the explanation above is correct, the answer is wrong. It's not 66 because you are subtracting 6 from x. This means x needs to be 6 above 72.

Here is my step-by-step solution:

x - 6 = 72       <-- Given; Corrected Equation

x - 6 + 6 = 72 + 6       <-- Addition Property of Equality

x = 78      <-- Result from Solution

Answer:

130.25 ft.

Step-by-step explanation:

The semi circle has a length 1/2 of the circumference of the circle with a diameter of 25

C = πd = 3.14(25)

So, the semi circle has a length = 1/2(3.14)25) = 39.25

The distance for the rectangle = 33 + 25 + 33 = 91

Therefore, the total perimeter = 91 + 39.25 = 130.25

6. C

Step-by-step explanation:

5. the mode is all the variables added together which is 100 or 100% divided by the number of them which is 4. 100 divided by 4 is 25 or 25%. The one that's equal to 25% is F which is soccer.

6. The relative frequency from what I can tell is the percentages of each of them. You just have to see how much space each of them takes up. C should be the answer.

Answer:

y = 6

Step-by-step explanation:

This is a special right triangle with angle measures 90° 60° 30°

the side length that sees angle measure 30 is represented with x

the side length that sees angle measure 90 is represented with 2x

and the side length that sees angle measure 60 is represented with x√3

the side length that sees angle measure 90 is given as 4√3 which means 2x = 4√3 divide both sides by 2

x = 2√3 now to find y, we need to multiply this value by √3

2√3 × √3 = 2 × 3

Answer:

5 ± 9.74

Step-by-step explanation:

Confidence interval, two - sample, t procedure ;

μ1 - μ2 = (x1 - x2) ± Tcritical*S

S = sqrt[(s1²/n1) + (s2²/n2)]

n1 = 9 ; n2 = 9 ; s1 = 8 ; s2 = 6 ; x1 = 30 ; x2 = 25

S = sqrt[(8^2/9) + (6^2/9)]

S = sqrt[11.111111]

S = 3.333

Tcritical at 99% confidence interval

df = 18 - 2= 16

Tcritical = 2.92

(30 - 25) ± 2.92*(3.333)
