Which type of function will most closely match the data?
A) decreasing linear function
B) increasing linear function
C) exponential decay function
D) exponential growth function
Answers
Answer:
D) Exponential Growth Function
Step-by-step explanation:
This is because in a linear equation, there is a constant 'slope' of how something increases like a specific amount but in this equation, the growth is by a specific percentage which allows for a difference in the amount each year. For example, a linear function would be if it increased by four dollars every year, so 2, 4, 6, 8,etc. But a exponential function would be like if it increased by for percent each year, so 2, 2.16, 2.25, 2.34, etc.

D) exponential growth function

Answer:
2520 stones which will cost £6300
Step-by-step explanation:
First find area of path:
630 x 120 = 75600 cm²
then find how many stones will be needed:
75600/30 = 2520
then find out the total cost:
2520 x 2.5 = £6300
Hope this helps!
Answer:
£125
Step-by-step explanation:
First, find perimeter.
630 + 630 + 120 + 120 = 1500
Divide by stone width.
1500 / 30 = 50
Multiply by the cost.
50 x 2.5 = 125

Sajia can sell 21 books she can sell if she comes back on sunday and the required inequality is
Solution:
Given that Sajia has 30 Books in her library
She sold 9 books at the thrift store on Saturday
To find: We have to write and solve an inequality to determine number of more books she can sell if she comes back on sunday
Let "x" be the number of more books she can sell if she comes back on sunday
We can write a inequality as:
Now moving 9 from L.H.S to R.H.S we get,
On solving 30 - 9 = 21,
So Sajia can sell 21 books she can sell if she comes back on sunday

What is substitution method?
To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.
Given that;
The function is,
⇒ f (x) = 2/3x + 3
Now,
Since, The function is,
⇒ f (x) = 2/3x + 3
Substitute x = 12 in above equation, we get;
⇒ f (x) = 2/3x + 3
⇒ f (12) = 2/3 × 12 + 3
⇒ f (12) = 2 × 4 + 3
⇒ f (12) = 11
Thus, The value of f (12) will be;
⇒ f (12) = 11
