Answer:

[tex]f(x)=4^{2x}[/tex]

Step-by-step explanation:

So we are given:

[tex]f(x)=(8^{\frac{2}{3}x})(16^{\frac{1}{2}x})[/tex]

and we have to find a function that will produce a similar graph. To do this, lets first simplify the given function.

Here are some properties of exponents that I will be using:

[tex]c^{\frac{n}{x}}=\sqrt[x]{c^{n}}=(\sqrt[x]{c})^{n}[/tex]

[tex](c^{x})^{n}=(c^{n})^{x}=c^{xn}[/tex]

[tex]c^{x}*c^{n}=c^{x+n}[/tex]

Now lets begin simplifying the function.

[tex]f(x)=(8^{\frac{2}{3}x})(16^{\frac{1}{2}x})[/tex]

[tex]=((\sqrt[3]{8^{2}})^{x})((\sqrt{16})^{x})[/tex]

[tex]=(4^{x})(4^{x})[/tex]

[tex]=4^{2x}[/tex]

So the correct answer would be [tex]f(x)=4^{2x}[/tex].

I hope you find my answer and explanation to be helpful. Happy studying.

Answer:

w = 4 or w=-3.5

Step-by-step explanation:

This likely factors into

(2w  + 7)(w - 4) = 0

in which case there are 2 factors.

2w + 7 = 0

w = - 3.5      or

w - 4 = 0

w = 4

  [tex]\textbf{D. }\sim p\rightarrow \,\sim q[/tex]

Step-by-step explanation:

Assuming your conditional is ...

  [tex]p\rightarrow q[/tex]

The inverse negates both clauses without changing their order.

The inverse is ...

  [tex]\boxed{\neg p\rightarrow \neg q}[/tex]

Answer:

  a14 = -40,960

Step-by-step explanation:

The sequence has a first term of 5 and a common ratio of -10/5 = -2, so the n-th term is given by ...

  an = a1·r^(n-1)

  an = 5·(-2)^(n-1)

The 14th term is then ...

  a14 = 5·(-2)^(14-1) = -5·2^13 = -5·8192

  a14 = -40,960

Answer:

y-6=1/2(x-2) or y=1/2x+5

Step-by-step explanation:

First, let's find the slope of the line.

Slope is y2-y1/x2-x1 or rise/run

Let's label (2,6) and (-2,4)

x1=2

y1=6

x2=-2

y2=4

now plug in the numbers

4-6/-2-2 = -2/-4=1/2

now, let's make it a line

Point slope form is y-y1=m(x-x1) (m is slope)

Plug the points in

y-6=1/2(x-2)

of course, you could always simplify it to y=1/2x+5 (y=mx+b) format if you want.

Hope this helps!

Answer:

x=2.6

Step-by-step explanation:

Answer :

9x² - 16 y²

★ Firstly, we'll break down 9 and 16 -

Here,

→ (3x)² - (4y)²

→ (3x - 4y) (3x + 4y)

Therefore, the factor of 9x² - 16y² is (3x - 4y) (3x + 4y).

Answer:

The area is the product of length and width, which is to say that the length and width are factors of the area.

Assuming the dimensions are integers, you want factors of 84 that differ by 5.

Step-by-step explanation:

... 84 = 1×84 = 2×42 = 3×28 = 4×21 = 6×14 = 7×12

The last of these pairs differ by 5, so ...

the length is 12 inches

the width is 7 inches.

The answer is l=12, w=7

Answer:

Step-by-step explanation:

Givens

Let the width be w

Let the length be w + 5

Let the area = 84

Equation

A = L*w

Solution

x(x + 5) = 84              Remove the brackets

x^2 + 5x = 84            Subtract 84 from both sides

x^2 + 5x - 84 = 0      This will factor

(x - 7)(x + 12) =0

x + 12 has no meaning. Geometry does not use negative numbers.

x - 7 = 0                      Add 7 to both sides

x = 7

The width = 7

The length = 7 + 5 = 12

Answer:

3

Step-by-step explanation:

Step 1:

12p - 13 + 3p = 32       Equation

Step 2:

15p - 13 = 32     Add

Step 3:

15p = 45       Add 13 on both sides

Step 4:

45 ÷ 15     Divide

Answer:

p = 3

Answer:

2.5 hours

Step-by-step explanation:

Given that :

Temperature in Neil's city :

72.6° and rising by 1.3° per hour

Temperature in Sheppard's city :

80.4° and dropping by 1.82° per hour

In how many hours will the temperature in Neil's city be no less than the temperature in Sheppard's city

Let number of hours = h

Hence, Neil city :

72.6 + 1.3h

Sheppard city:

80.4 - 1.82h

72.6 + 1.3h ≥ 80.4 - 1.82h

1.3h + 1.82h ≥ 80.4 - 72.6

3.12h ≥ 7.8

h ≥ 2.5

Two and half hours (2 hours 30 minutes)

Answer:

Urban area

Step-by-step explanation:

F(x) = 3x^2 + 1, G(x) = 2x - 3, H(x) = x

F(3) = 3(3)^2 + 1 = 27 + 1 = 28

G(4) = 2(4) - 3 = 8 - 3 = 5

2H(5) = 2(5) = 10

F(3) + G(4) - 2H(5) = 28 + 5 - 10

F(3) + G(4) - 2H(5) = 23

question 2

Given: F(x) = 5x - 6 and G(x) = x - 4

(FoG) (x) = F(G(x)) = 5(x-4) - 6

= 5x - 20 - 6

= 5x - 26

Inverse

x = 5y - 26

5y = x + 26

y = x/5 + 26/5

So

(FoG) -1 (x) = x/5 + 26/5

Answer:

Slope intercept: y = 0x + 2

Point slope: y - 2 = 0(x + 5)

Standard: 0x - y = 2
