Answer:

answer is C f(n) = 4(3)n; f(5) = 972

Step-by-step explanation:

i took the test, also

The graph is an illustration of an exponential function

The true statement is (d) [tex]\mathbf{f(n) = 4(3)^{n-1}}[/tex], [tex]\mathbf{f(5) = 324}[/tex]

An exponential function is represented as:

[tex]y = ab^{x-1}[/tex]

From the graph, we have the following points

[tex](x_1,y_1) = (1,4)[/tex]

[tex](x_2,y_2) = (2,12)[/tex]

So, we have:

[tex]y = ab^{x-1}[/tex] --------- [tex](x_1,y_1) = (1,4)[/tex]

[tex]4 = ab^{1-1}[/tex]

[tex]4 =ab^0[/tex]

[tex]4 =a \times 1[/tex]

[tex]4 =a[/tex]

[tex]a = 4[/tex]

[tex]y = ab^{x-1}[/tex] --------- [tex](x_2,y_2) = (2,12)[/tex]

[tex]12 = ab^{2-1[/tex]

[tex]12 = ab[/tex]

Substitute [tex]a = 4[/tex]

[tex]12 = 4b[/tex]

Divide both sides by 4

[tex]3 = b[/tex]

[tex]b =3[/tex]

Recall that:

[tex]y = ab^{x-1}[/tex]

So, we have::

[tex]y = 4(3)^{x-1}[/tex]

Express as a function of n

[tex]\mathbf{f(n) = 4(3)^{n-1}}[/tex]

Substitute 5 for n, to calculate the 5th term

[tex]\mathbf{f(5) = 4(3)^{5-1}}[/tex]

[tex]\mathbf{f(5) = 4(3)^4}[/tex]

[tex]\mathbf{f(5) = 324}[/tex]

Hence, option (d) is correct

Step-by-step explanation:

When a triangle is dilated, the size of the triangle changes.

The coordinate of G' after dilation is: (a) [tex]\mathbf{(-\frac 23,\frac 43)}[/tex]

The vertices are given as:

[tex]\mathbf{G = (-2,4)}[/tex]

[tex]\mathbf{H = (3,6)}[/tex]

[tex]\mathbf{J = (3,-2)}[/tex]

The scale factor (k) is given as:

[tex]\mathbf{k =\frac 13}[/tex]

So, the image of G is calculated as:

[tex]\mathbf{G' = k \times G}[/tex]

This gives:

[tex]\mathbf{G' = \frac 13 \times (-2,4)}[/tex]

[tex]\mathbf{G' = (-\frac 23,\frac 43)}[/tex]

Hence, the coordinate of G' after dilation is: (a) [tex]\mathbf{(-\frac 23,\frac 43)}[/tex]

Answer:

x=60

Step-by-step explanation:

Answer:   The equation  60 + x= 3x -70   could be set up to solve for x.  

Step-by-step explanation:

The two remote  interior angles sums will equal to the exterior angle .

Meaning that angle 60 plus angle x has to equal to angle 3x -70.

60 + x= 3x -70       Now solve for x by adding 70 to both sides

+70             +70

  130 + x = 3x      Now subtract x from both sides

         -x      -x

  130 = 2x        Divide both sides by

Step-by-step explanation:

The relative frequency of the coin landing heads up is 0.4 or 40%.

Step-by-step explanation:

We are given that,

Total number of times coin is tossed = 600

Number of times heads comes = 240

Since, 'relative frequency' is the fraction of number of times an event occurs and the total number of events.

Thus, the relative frequency that heads comes = \frac{240}{600}

600

240

i.e. Relative frequency that heads comes = 0.4 or 40%

Thus, the relative frequency of the coin landing heads up is 0.4 or 40%.

Answer: 40%

Answer:

(A) 8.8 years

Step-by-step explanation:

Given that the principal amount = $ 3100

Rate of compound interest = 8% compounded semiannually.

The given formula is

[tex]A=P\left(1+\frac{r}{n}\right)^{nt}[/tex]

Where A is the final amount, P is the principal amount, r is the rate of compound interest, t is the time and n is the number of times per year the interest is compounded.

From the given condition,

P=$3100

r= 8%=0.08 compounded semiannually

n=2

A=2 x 3100=$ 6200.

Put all these in the given formula to get the required time, we have

[tex]6200=3100\left(1+\frac{0.08}{2}\right)^{2t}[/tex]

[tex]\Rightarrow \left(1+0.04\right)^{2t}=6200/3100[/tex]

[tex]\Rightarrow 1.04^{2t}=2\\\\\Rightarrow 2t\log_{10}(1.04)=\log_{10}(2)\\ \\\Rightarrow 2t =\frac{\log_{10}(2)}{\log_{10}(1.04)}\\\\\Rightarrow 2t =17.673\\\\\Rightarrow t = 17.673/2=8.8365\\[/tex]

On rounding to the nearest tenth of a year, t=8.8 years.

So, the invested amount will be double in  8.8 years.

Hence, option (A) is correct.

I think you mean to say "hypotenuse". If so, then use the pythagorean theorem to get the following

a^2 + b^2 = c^2

16^2 + 20^2 = c^2

256 + 400 = c^2

656 = c^2

c^2 = 656

c = sqrt(656)

c = sqrt(16*41)

c = sqrt(16)*sqrt(41)

c = 4*sqrt(41)

The hypotenuse is exactly 4*sqrt(41) units long

This is approximately 25.612 when you use your calculator.
