An exponential decay function that represents the population after t years is [tex]\rm f (x) = 250000 (0.965)^t[/tex].

An exponential function can be represented in the form f(x) = aˣ.

The population of a city was 250,000

Rate of decay is 3.5%

100 -3.5 = 96.5%

The population after t years is represented by the function

[tex]\rm f (x) = 250000 (0.965)^t[/tex]

Step-by-step explanation:

x + 4 is multiplied by each term inside the second parenthesis

D. (x+4) (6x^2) + (x + 4)(2x)

Answer:

a) 39^2 = x^2 + 15^2

39^2 - 15^2 = x^2

Answer:

r = -13

Step-by-step explanation:

Step 1: distribute the signs & terms outside the parenthesis. on the left side, distribute a - sign (same thing as -1) and on the right side distibute -7

12 - (3r) - (+2) = (-7)r + (-7)6

Step 2: algebraically simplify

10 - 3r = -7r - 42

52 = -4r

r = -13

Answer: 9(x+8)=7

Step-by-step explanation:

m∠3 = 7x - 10

m∠6 = 5x + 10

m∠3 = m∠6

7x - 10 = 5x + 10

7x - 5x = 10 + 10

2x = 20

Step-by-step explanation:

Answer:

75

Step-by-step explanation:

5^-2 = 5*5 = 25/1

because it's (-) you need to flip it so 1/25

3/1 ÷ 1/25 = 3/1 × 25/1

because when you divide fraction you need to keep the first fraction as it is and change the symbol from (÷) to (×) and flip the second fraction. (KCF simple way to memorise it)

So  3/1 × 25/1 = 75/1

75/1 is same as 75

I'm not sure if this is correct but I got the answer, 316.

Step-by-step explanation:

I used the process PEMDAS

320-{24÷3×[8÷2−(8−6)]}

320-{24÷3×[8÷2−2]}

320-{24÷3×[4−2]}

320-{24÷3×2}

320-{24÷6}

320-4

= 316

Answer: A

Step-by-step explanation:

If you plug in the numbers from the x column into the equation in the place of x, you can figure out the answer.

Example:    -10x - 15

                   -10(1) - 15 = -25

                   -10(2) - 15 = -35 and so on...

Hooke's law relates the force applied on an elastic material to its extension. Therefore, the answers to the questions are:

a. F = ks

b. The spring stretched 0.035 m (3.5 cm) when a weight of 14 N is included.

Hooke's law states that provided the extension limit of an elastic material is not exceeded, the force applied is directly proportional to its extension.

i.e F = ke

where F is the force applied to the material, k is the spring constant of the material, and e is the extension.

Considering the conditions in the given question then, we have:

a. The equation that relates F and S for the spring on the jumper is:

F = ks

b. Given that: F = 8 N, while s = 2 cm (0.02 m).

Then;

F = ks

8 = k(0.02)

k = [tex]\frac{8.0}{0.02}[/tex]

  = 400

k = 400 N/m

So that, the stretch in the spring when 14 N weight is included is:

F = ks

14 = 400 x s

s = [tex]\frac{14}{400}[/tex]

  = 0.035

s = 0.035 m

Thus the spring was stretched by 0.035 m (3.5 cm) when a weight of 14 N was included.

Answer:

A

Step-by-step explanation:

is the answer

The value of P(B|A) is 0.25.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

We have P(A) = 0.40 and P(B) = 0.5

and, P(A and B) = 0.10

Using Conditional Probability

P(B|A) = P(A ∩ B)/P(A)            

Substitute the values of P(A), P(B) and P(A ∩ B),

P(B|A) = 0.10/ 0.40

P(B|A) = 0.25

Answer:

15 in

Step-by-step explanation:

You have to use pythagoras' theorem, which is a^2=b^2+c^2 (a being the hypotenuse), because it is a right-angled triangle.

so you do 9^2+12^2, which equals 225. Then you square root that to get 15.
