4 Find a formula for the exponential function passing through the points (-2, 4/9) and (3, 108)​

Answers

Answer 1

Answer:

  f(x) = 4·3^x

Step-by-step explanation:

We assume the function will be of the form ...

  f(x) = a·b^x

Substituting the given values, we can find 'a' and 'b'.

  4/9 = a·b^(-2)

  108 = a·b^3

Dividing the second equation by the first gives ...

  108/(4/9) = b^(3 -(-2))

  243 = b^5

  b = 3 . . . . . . 5th root

Using the second equation, we can find 'a':

  108 = a·3^3 = 27a

  a = 108/27 = 4

The formula for the exponential function is ...

  f(x) = 4·3^x

If the function f (x) is defined by f(x) =x over 2 minus 6

Answers

Depending on how it is written, it could be either of these following solutions:

f(x) = x/2 - 6     or     f(x) = x/(2-6)

For the first, we solve for x by replacing f(x) with 0

x/2 - 6 = 0

x/2 = 6

x = 3

For the second, do the same

x/(2-6) = 0

x/-4 = 0

x = 0

Dante runs 7 miles in 60 minutes. At the same rate, how many miles would he run in 24 minutes?

Answers

Answer: 2.8 miles

Step-by-step:

We can write it in the proportion [tex]\frac{7}{60} = \frac{x}{24}[/tex]

where x is our number of miles trying to find

We now cross multiply or use the butterfly method which I will demonstrate both

Cross Multiply

We multiply the numerator with the dominator

so [tex]7 multiplied by 24[/tex]

and [tex]60 multiplied by x[/tex]

[tex]7*24=60x[/tex]

[tex]168=60x[/tex]

[tex]\frac{168}{60} =\frac{60x}{60}[/tex]

[tex]2.8=x[/tex] or [tex]x=2.8[/tex]

Now for the

Butterfly Method

You would do 7 times 24 divided by 60 or [tex]\frac{7*24}{60}[/tex]

Then[tex]\frac{168}{60}[/tex] simplify

[tex]2.8[/tex] so 2.8 miles in either method

The mean of 4 numbers is 40, what is the sum of the 4 numbers

Answers

Answer:

the sum of 4 numbers is 160

Step-by-step explanation:

Let 4 numbers be a, b, c, d

Mean of those 4 numbers is: (a+b+c+d) : 4 = 40

So the sum of 4 numbers is: (a+b+c+d) = 40 x 4 = 160

=> 160 is the sum of 4 numbers

Answers

1.

x^2 + 3x = 28

x^2 + 3x - 28 = 0

(x + 7)(x - 4) = 0

Therefore,

x = -7 or 4

2.

3s^2 -6s = 12s

3s^2 - 18s = 0

s(s - 6) = 0

Therefore,

s = 0 or 6

3.

t^2 + 2t + 1 + t^2 -16t + 64 = 45

2t^2-14t + 20 = 0

t^2 -7t + 10 = 0

(t - 5)(t - 2) = 0

Therefore, t = 5 or 2

4 .

3(x^2 + 4x + 4) + 5(x^2 - 4x + 4) = 80

8x^2-8x + 32 = 80

x^ 2 - x + 4 = 10

x^2 - x - 6 = 0

(x - 3)(x + 2) = 0

Therefore,

x = 3 or -2

5.

since r and t are close on the keyboard, I can assume one was a typo, but it wouldn’t matter which.

8 + t(t-3) = -4(t-3)

8 + t^2 - 3t + 4t - 12 = 0

t^2 + t - 4 = 0

Using the quadratic formula,

t = (-1+-sqrt(1^2 -4(1)(-4)))/2(1)

t = (-1+-sqrt(17))/2

La función de costos para una compañía es C=125q + 13500 y su punto de equilibrio es q=270. Plantear la función de Utilidad

Answers

Based on the information given, the total cost incurred based on the equation given as C= 125q + 13500 will be 47250.

From the information given, the cost function is given as C=125q + 13500 while the value of q is given as 270. Therefore, on order to find the cost, we'll slot in the value of q into the equation given. This will be:

C=125q + 13500

C = 125(270) + 13500

C = 33750 + 13500

C = 47250

In conclusion, the cost is 47250.

Answers

Answer: y = (-2/3)x - 3

Step-by-step explanation:

We'll be using y = mx + b

m = slope

b = y-intercept

Because we know this line will pass through -3, -1, we can input that.

y = mx + b

-1 = (-2/3)(-3) + b

-1 = 2 + b

b = -3

We can input that now to get the equation
