The acceleration of the car is 6m/s²

Acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities. Acceleration is measured in meter per second squared

It can also be defined as the ratio of the change in velocity to the time

Therefore acceleration is given as (v-u)/t

where v is the final velocity and u is the initial velocity, t is the time

therefore a= 30-0/5

a= 30/5

a= 6m/s²

therefore the acceleration of the car is 6m/s²

Using an exponential function, the rate of growth is 20.482%, the number of bacteria after two hours is 12048.21 and the doubling time of the bacteria is 3.7 hours

Exponential function, as its name suggests, involves exponents. But note that, an exponential function has a constant as its base and a variable as its exponent but not the other way round (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function.

A) The rate of growth can be calculated as

Data;

Writing this in an exponential function;

A = P(1 + r)ˣ

10000 = 8300(1 + r)¹

r = 0.2048

r = 20.482%

B)

Substituting the values into the function above

x = 2

A = 8300(1 + 0.2048)²

A = 12048.21

C)

For the bacterial to double, the time will be

Step-by-step explanation:

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

The percentage error of the measurement is 47.8%.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

The actual length of the line = 2.3 inches

The measured length of the line = 2.2 inches

The error length of the line.

= 2.3 - 2.2

= 1.1 inches

The percentage error of the measurement.

= 1.1/2.3 x 100

= 47.8%

Thus,

The percentage error of the measurement is 47.8%.

Answer: 1560

Step-by-step explanation: The average rate of change of a function over an interval is the total change in the value of the function divided by the length of the interval. In this case, the function is f(x) = 10(2)^x and the interval is [3, 5].

To find the average rate of change of the function over the interval, we can first evaluate the function at the two endpoints of the interval, which are x = 3 and x = 5. At x = 3, the function has a value of f(3) = 10(2)^3 = 80. At x = 5, the function has a value of f(5) = 10(2)^5 = 3200.

The total change in the value of the function over the interval is then the difference between the values at the two endpoints, which is f(5) - f(3) = 3200 - 80 = 3120.

The length of the interval is 5 - 3 = 2, since it goes from x = 3 to x = 5. Therefore, the average rate of change of the function over the interval is the total change in the value of the function divided by the length of the interval, which is (3120) / 2 = 1560.

Therefore, the average rate of change of the function f(x) = 10(2)^x on the interval [3, 5] is 1560.

The required sum of the series sum from n equals 1 to infinity is -9/5

geometric series, in science, a  infinite series of the structure a + ar + ar^2 + ar^3+⋯, where r is known as the common ratio. A basic model is the mathematical series for a = 1 and r = 1/2, or 1 + 1/2 + 1/4 + 1/8 +⋯, which joins to an amount of 2 (or 1 on the off chance that the initial term is barred).

We have,

GP; -3(3/8), -3(3/8)^2,................ -3(3/8)^∞

Common ratio(r) = 3/8, a = -9/8

S(1 to ∞) = a/(1 - r)

S(1 to ∞) = -9/8(1 - 3/8)

S(1 to ∞) = -9/8/5/8

S(1 to ∞) = -9/5

Thus, sum of geometric series is -9/5.

a) The net for the sale is: $4,500

b) The capital gain is $2,200

We know that you had 100 shares, now the value of each of these is $45.00, then the amount that you make if you sell the 100 shares is:

S = 100*$45.00 = $4,500

The capital gain is the difference between the amount we found above and the amount you paid for the shares.

The price of the shares was $23.00, then the amount you paid is:

191 of adult plates and 81 child plates were sold.

Two or more expressions with an Equal sign is called as Equation.

Given,

Adult plate costs A= $8

Child plate costs C=$5

Total plates sold is 272

A+C=272..(1)

8A+5C=1,933..(2)

C=272-A

Substitute in equation 2

8A+5(272-A)=1933

8A+1360-5A=1933

1360+3A=1933

Subtract 1360 on both sides

3A=1933-1360

3A=573

Divide both sides by 3

A=191

Now substitute A value in 1

191+C=272

Subtract 191 on both sides

C=272-191

C=81

Hence, 191 of adult plates and 81 child plates were sold.

Answer:

None of the values.

Step-by-step explanation:

Simplify the given equation.

First, simplify by combining like terms. Like terms are terms that share the same amount of the same variables:

4 = m + 5 - 2m

4 = (m - 2m) + 5

4 = -m + 5

Next, isolate the variable, m. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

-

First, subtract 5 from both sides of the equation:

4 = -m + 5

4 (-5) = -m + 5 (-5)

4 - 5 = -m

-1 = -m

Next, isolate the variable m. Remove the negative sign by dividing -1 from both sides of the equation:

(-1)/-1 = (-m)/-1

m = -1/-1 = 1

None of the values will make the equation true, as 1 is not a given value.
