The average rate of change of the function between the points is -4/7

The constant average rates of change of a function is also regarded as the slope or the gradient of the function

Here, we have the points to be

(-3, 16) and (4, 12)

The average rates of change between these points is calculated as

Average rate of change = [f(b) - f(a)]/[b - a]

So, we have

Average rate of change = [12 - 16]/[4 + 3]

Evaluate the sum and the difference

So, we have

Average rate of change = -4/7

Hence, the average rate of change between the points is -4/7

The phrase simplifies the way to make something less challenging to do or understand. So, by lowering or simplifying the fractions approach we make the fraction as easy as possible. We do this by dividing the numerator and the denominator by using the most important number which could divide into both numbers precisely.

Cross-cancellation is a simplification that may be executed earlier than. that is wonderful because simplifying earlier than the method while you do multiply, you'll have smaller numbers, and smaller numbers are easier to paint with.

Simplifying a rectangular root just means factoring out any best squares from the radicand, shifting them to the left of the unconventional image, and leaving the opposite factor within the radical image. If the variety is an ideal square, then the novel signal will disappear when you write down its root.

The inequality comparing the elevations is -220 > -282  and -220 feet is closer to sea level.

The elevation of Bad Water Basin = -282 feet

The elevation of the Salt Creek = -220 feet

We are asked to compare the elevations and find which is greater than the other.

So we know that on a number line -220 is greater than -282.

This can be understood in the same sense that -1 > -2 on the number line.

So the inequality comparing the elevations is -220 > -282.

Now consider the sea level as 0 on the number line.

Then clearly -220 is closer to 0 on number line.

Hence the elevation closer to the sea level = -220 feet.

Answer:

3 is the greatest common factor that can go into 9 and 48

The greatest common factor of 9 and 48 is 3.

The greatest common factor (GCF) is the largest positive integer that divides two or more numbers without leaving a remainder. In other words, it is the largest number that is a factor of both (or all) of the given numbers.

For example, the GCF of 12 and 18 is 6, beca

To find the greatest common factor (GCF) of 9 and 48, we need to determine the largest number that both 9 and 48 can be divided by evenly.

We can start by listing the factors of each number:

9: 1, 3, 9

48: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48

Then we can look for the greatest factor that appears in both lists. In this case, the greatest common factor of 9 and 48 is 3, since it is the largest number that appears in both lists of factors.

Therefore, the GCF of 9 and 48 is 3.

When zulaki recorded -3/10 degrees celcius as the starting temperature of a salt water solution and recorded 1/5 degrees as the. ending temperature, the change in temperature is 1/2 degree.

It should be noted that from the information, science class, zulaki recorded -3/10 degrees celcius as the starting temperature of a salt water solution and recorded 9/10 degrees as the. ending temperature.

Therefore,the change in temperature will be the subtraction of the temperature given. This will be illustrated as:

= 1/5 - (-3/10)

= 1/5 + 3/10

= 2/10 + 3/10

= 5/10

= 1/2

The solved logarithmic function is log (2x + y) = 4 log (2) and log (4x - y) = 0 for 2x + y = 2⁴ and 4x - y = 1 respectively.

What is a logarithmic and exponential function?

Logarithmic functions and exponential functions are inverses of each other. The logarithmic function is denoted by using the word log while exponential by using the alphabet,  e. For example log 10 = 1 and e^2.

Solving the given expressions: 2x + y = 16 and 4x - y = 1

Applying given properties of logarithmic and exponential function;

log a + log b = log (ab)

4 log x = log x⁴

e^(log x) = 1

e^(x + y) = (e^x) × (e^y)

Take the expression, 2x + y = 16

Applying log on both sides, we get,

log (2x + y) = log (16)

log (2x + y) = log (2⁴)

log (2x + y) = 4 log (2)

To Check Results,

Taking exponential on both sides,

e^[log (2x + y)] = e^(4 log 2)

2x + y = e^(log 2⁴)

2x + y = 2⁴

2x + y = 16

Thus, the answer is verified.

Take expression, 4x - y = 1

Applying log on both sides, we get,

log (4x - y) = log 1

log (4x - y) = 0

To Check Results,

Taking exponential on both sides,

e^[log (4x - y)] = e^0

4x - y = 1

Thus, the answer is verified.

Hence, the solved expression is log (2x + y) = 4 log (2) and log (4x - y) = 0 for 2x + y = 2⁴ and 4x - y = 1 respectively.

The cost of one packet of biscuit is £1.60.

The total amount that Aisha paid for the items she purchased is a function of the total cost of bread rolls, ketchup and biscuits.

Total cost of the items purchased = total cost of bread rolls + total cost of biscuits + total cost of ketchup

Total cost of bread rolls = cost per packet x number of packets bought

2 x £1.20 = £2.40

Total cost of ketchup = cost of one bottle x number of bottles bought

1 x £2.10 = £2.10

Total cost of biscuits = cost of one packet  x number of packets bought

3 x b = 3b

Total cost = £2.40 + £2.10 + 3b = £4.50 + 3b

Total amount paid by Aisha = note given - change received

£10 - 70p

£10 - £0.70 = £9.30

Total amount paid by Aisha =  total cost

£9.30 = £4.50 + 3b

The range of the function f(x) = 2.250x is 22.5 <= f(x) <= 36

The range of a function is the set of output values of the graph.

This in other words mean the range of a function is the set of y values of the graph.

The function is given as

f(x) = 2.250x

Where there are at least 10 but no more than 16 players on the baseball team

This means that the domain of the function is

10 <= x <= 16

Substitute the domain values in the given function

So, we have

f(x) = 2.250x

f(10) = 2.250 * 10

Evaluate

f(10) = 22.5

f(x) = 2.250x

f(16) = 2.250 * 16

Evaluate

f(16) = 36

The range of the function is then represented as

f(10) <= f(x) <= f(16)

So, we have

22.5 <= f(x) <= 36

Hence, the range of the function f(x) = 2.250x is 22.5 <= f(x) <= 36
