Answer:

C - 21:28

Step-by-step explanation:

this is solved by a little bit of trial and error. divide the possible answer numerators by 15, and check if it's the same for the denominator.

For C I did this:

Divided the denominators: 28 ÷ 20 = 1.4....so that's 1.4.

Let's test it out for the numerator now. 21 ÷ 15 = 1.4.

So there's your answer.

Answer:

C=S/1+R ( The + is a ___  so 1+R is under S)

Step-by-step explanation:

Answer:

0.75 mg

Step-by-step explanation:

From the question given above the following data were obtained:

Original amount (N₀) = 1.5 mg

Half-life (t₁/₂) = 6 years

Time (t) = 6 years

Amount remaining (N) =.?

Next, we shall determine the number of half-lives that has elapse. This can be obtained as follow:

Half-life (t₁/₂) = 6 years

Time (t) = 6 years

Number of half-lives (n) =?

n = t / t₁/₂

n = 6/6

n = 1

Finally, we shall determine the amount of the sample remaining after 6 years (i.e 1 half-life) as follow:

Original amount (N₀) = 1.5 mg

Half-life (t₁/₂) = 6 years

Number of half-lives (n) = 1

Amount remaining (N) =.?

N = 1/2ⁿ × N₀

N = 1/2¹ × 1.5

N = 1/2 × 1.5

N = 0.5 × 1.5

N = 0.75 mg

Thus, 0.75 mg of the sample is remaining.

The duration of decay is the same as the half-life of radium, therefore,

half the mass  of radium will remain after 6 years.

Response:

The given mass of the sample of radium, N₀ = 1.5 mg

The half-life of radium = 6 years

Required:

The amount of the sample that will remain after 6 years

Solution:

Let N(t) represent the mass of the sample that remains after 6 years, we have;

[tex]N(t) = \mathbf{N_0 \cdot \left(\dfrac{1}{2} \right)^{\dfrac{t}{t_{1/2}} }}[/tex]

Which gives;

[tex]N(6) = \mathbf{1.5 \times \left(\dfrac{1}{2} \right)^{\dfrac{6}{6} }} = 0.75[/tex]

Answer: y = 7- 5x

Step-by Step Explanation: The variable x is multiplied by a larger value here; it's multiplied by 5. So I should expect that my y-values will grow fairly quickly. This means that I should expect a fairly "tall" graph.

First I'll do the T-chart.

T-chart

This equation is an example of a situation in which you will probably want to be particular about the x-values you pick. Because the x is multiplied by a relatively large value, the y-values grow quickly. For instance, you probably wouldn't want to use x = 10 or x = –7 as inputs. You could pick larger x-values if you wished, but your graph would very quickly get awfully tall.

I can see, from my T-chart, that my y-values are getting pretty big on either end (that is, in the positive numbers above the horizontal axis, and in the negative numbers below). I don't want to waste time computing points that will only serve to make my graph ridiculously large, so I'll quit with what I've got so far. But I'm glad I plotted more than just two points, because lines that start edging close to vertical can easily go wrong, if I'm not neat in my work.

Here's my graph:

Answer:

It's A and the answer is 4^x

Step-by-step explanation:

The exponential function that models the data is f(x) = [tex]4^x[/tex].

A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable).

The characteristic that every input is associated to exactly one output defines a function as a relationship between a set of inputs and a set of allowable outputs.

We have a table.

The given function is not a linear because the difference of two consecutive term is not constant.

Now, the ratio

1/(1/12)= 12

12/1= 12

144/12= 12

1728/ 144= 12

If the ratio is same then the function is Exponential.

So, the exponential function is

f(x) = [tex]4^x[/tex]

The enlargement transformation applied to the rectangular figure gives

a rectangle that is enlarged and similar to the figure.

Correct response:

The given dimensions of the picture are;

Height, [tex]\overline{MN}[/tex] = 6 in.

Width, [tex]\overline{LP}[/tex] = 4 in.

The length of QL' = 12  + 42 = 54

By similar triangles, we have;

[tex]\dfrac{\overline{L'P'}}{\overline{LP}} = \mathbf{ \dfrac{\overline{QL'}}{\overline{QL}}}[/tex]

Which gives;

[tex]\dfrac{\overline{L'P'}}{6} = \mathbf{ \dfrac{54}{12}}[/tex]

[tex]\overline{L'P'} = \dfrac{54 }{12} \times 6 = \mathbf{27}[/tex]

Given that an enlargement gives similar figures, we have;

[tex]\dfrac{\overline{L'P'}}{\overline{LP}} = \mathbf{\dfrac{\overline{L'M'}}{\overline{LM}}} = Scale \, factor \ of \ the \ enlargement[/tex]

Therefore;

[tex]\dfrac{27}{6} = \dfrac{\overline{L'M'}}{4}[/tex]

Which gives;

[tex]\overline{L'M'} = \dfrac{27}{6} \times 4 = \mathbf{ 18}[/tex]

The area of the enlarged picture is, A = [tex]\overline{L'M'}[/tex] × [tex]\overline{L'P'}[/tex]

Which gives;

A = 27 × 18 = 486

Step-by-step explanation:

Answer:

0.0833333 (3 is repeating)

Step-by-step explanation:

The apprοximate prοbability that Ankit will make all three shοts is 0.405 οr 40.5%. Thus, option a is correct.

A prοbability distributiοn knοwn as the binοmial distributiοn is used tο characterize the number οf successes in a certain number οf independent trials, where each trial has οnly οne οf twο pοtential οutcοmes (success οr failure) and the chance οf success is cοnstant acrοss all trials. Fοr determining the likelihοοd οf achieving a certain number οf successes in a set number οf trials, it is utilised.

Given, Ankit makes 74% οf the free thrοws.

Using binοmial distributiοn we have:

[tex]$\rm P(X=k)= (^nC_k) \times p^{k} \times (1-p)^{(n-k)}$[/tex]

Fοr k = 3 we have:

[tex]$ \rm P(X=3)=(^3C_3) \times 0.74^{3} \times (1-0.74)^{(3-3)}$[/tex]

[tex]$ \rm P(X=3)=0.74^{3}$[/tex]

P(X=3) ≈ 0.405

Hence, the apprοximate prοbability that Ankit will make all three shοts is 0.405 οr 40.5%.
