The growth factor for the annual rate of change +0.1 % is 1.001.
A quantity must vary by a specific percentage each time period in order for growth or decay to be exponential.
With the function displayed to the right, you may represent exponential growth or decay.
A(x) = a( 1 + r)ˣ
Where A is the amount after x time periods, a is the initial amount, x is the number of time periods, and r is the rate of change.
Now, we have the annual rate of change as:
r = + 0.1% = + 0.1 / 100 = + 0.001
From the function A(x) = a( 1 + r)ˣ , the corresponding factor is 1 + r.
So, let B = 1 + r
B = 1 + r
B = 1 + (+0.001)
B = 1.001
Now, the value of B is greater than 1 therefore, the corresponding growth factor is 1.001.

Write each expression as a single logarithm.
log₆24-log₆4
The logarithm expression can written as log₆ 24 - log₆ 4 = 1
There are 7 properties of logarithms: Product Rule, Quotient Rule, Power Rule, Zero Rule, Identity Rule, Inverse Property of Logarithm, Inverse Property of Exponent, Change of base formula.
In this question, we use the Quotient Rule of logarithms.
Quotient rule of logarithms states that the logarithm of a quotient is equal to a difference of logarithms.
Example: logₐ (x/y) = logₐ x - logₐ y
So, we get that:
log₆ 24 - log₆ 4
= log₆ (24 / 4)
= log₆ 6
which will also be equal to
= 1
Therefore, in the equation log₆ 24 - log₆ 4 = 1 and the property of the quotient rule of logarithms is used.

Two angles form a linear pair. The measure of one angle is 3.5 times the measure of the other angle. Find the measure of each angle.
The angles which form a linear pair are 40° and 140°.
Linear pair is defined as the pair of angles which add up to 180 degrees.
When two straight lines intersect with one another then 4 angles are formed. Any two adjacent angles thus formed are a linear pair.
Let us consider one angle be x . Now another angle is 3.5 times this angle.
Therefore measure of second angle = 3.5x
Now if these two angles are a linear pair then their sum will be equal to 180°.
Therefore we can form a linear equation in x and solve to get the values of the angles.
∴3.5x + x = 180°
or, 4.5x = 180°
or, x = 180 ÷ 4.5
or, x = 40°
Measure of the second angle = 3.5 × 40° = 140°
Hence the two angles which form a linear pair are 40° and 140° .

b) The distance between the two cities = 125 km.
c) The average speed during 20 the journey = 62.5 km/hr.
What is defined as the acceleration?Acceleration is the rate during which velocity changes over time, both in terms of speed and direction. A point or takes place in a straight line is sped up if it quickens or decelerates. Even if the speed is constant, motion on such a circle is accelerated because the direction is constantly changing.For the given question;
Every horizontal block is 1/8 hour = 7.5 minutes long.
Each vertical block has a speed of 10 km/hr:
The table drawn as per the data given in the table:
Time Velocity km/hr
0 Min ( 0 hr) ---> 0
15 Min (1/4 hr) --> 50
45 Min (3/4 hr) --> 50
60 MIn ( 1 hr) --> 100
90 Min ( 3/2 hr) ---> 100
120 Min ( 2hr) ---> 0
The formula for acceleration:
Part a: Acceleration = final velocity - initial velocity / final time - initial time
Acceleration in the first 15 minutes: (1/4 hr) = (50 - 0)/(1/4 - 0)
= 50/(1/4)
=200
Thus, acceleration in the first 15 minutes is 200 kmph.
Part b: Distance among two cities:
= (1/2)(0 + 50)(1/4 - 0) + 50 * (3/4 - 1/4) + (1/2)(50 + 100)(1 - 3/4) + 100 * (3/2 - 1) + (1/2)(100 + 0)(2 - 3/2)
= 25/4 + 25 + 75/4 + 50 + 25
= 125
The difference distance for two cities is 125 kilometers.
Part c: Average speed = distance/2
Average Travel Speed = 125/2 = 62.5 km/hr
Therefore,
a: Acceleration in the first 15 minutes = 200 km/h²
b: The distance between two cities is 125 kilometers.
c: The average speed of the journey is 62 miles per hour.

a speed of 60 mph, he will have a fuel efficiency of 34
miles per gallon. what is the average rate of change of
the fuel efficiency as the speed drops from 75 mph to
60 mph?
The average rate of change of fuel efficiency = -3 gallon per hour
Fuel efficiency of the cooper when driving at a speed of 75 mph = 29 miles per gallon
Fuel efficiency of the cooper when driving at a speed of 60 mph = 34 miles per gallon
Let y₁ = 75 mph, y₂ = 60 mph
and x₁ = 29 miles/gallon , x₂ = 34 miles /gallon
Then the average rate of change of fuel efficiency = (y₂-y₁)/(x₂-x₁)
= (60 - 75)/(34-29)

Unit rate is defined as per unit time. Unit rate can be anything from speed, acceleration or any other measurement.
The quantity that is achieved in a single unit of time is called the unit rate.
The unit rate is calculated by dividing the total amount by total time that is taken to complete the total amount.
Here Darrell walks 90 meters in 60 seconds.
The unit time to be considered here is 1 second.
so Darrell walks a certain amount of distance in 60 seconds.

Greg is purchasing ink cartridges for his computer. Each ink cartridge costs $35.99 and comes with a $10 rebate. How much will Greg pay for one ink cartridge after the rebate?
*Rebate is a refund of part of the amount paid for an item
Greg will pay $25.99 for one ink cartridge after the rebate.
As stated in the question, rebate is the refund that customer receives. It is part of the amount paid. So, it can be easily deducted from the total amount. To find the payment amount, we will simply subtract rebate amount from ink cartridge cost.
Keep the values in mentioned relation to find the payment amount to be given by Greg for one ink cartridge.
Payment = 35.99 - 10
Performing subtraction to find the payment amount to be given by Greg
Payment = 25.99
Hence, the payment of $25.99 will be done by Greg for one ink cartridge after the rebate.
