Answer:
7
Step-by-step explanation:
Using the definition
n
= 
where n! = n(n - 1)(n - 2)..... 3 × 2 × 1
Then
7
= 
= 
← cancel out the multiples 6 ×5 × 4 × 3 × 2 × 1 , then
7 = 7
Answer: The square root of nine is three. Divisions means the operation which is the opposite of multiplication.
Step-by-step explanation:
The population of the island with growth rate of 4.5% per year and the current population is 1500 is 1953 after 6 years.
<h3>How to solve an
exponential function</h3>
Let y represent the population after x years.
Given that the growth rate is 4.5% per year and the current population is 1500.
Hence a = 1500, b = 100% + 4.5% = 104.5% = 1.045
y = 1500(1.045)ˣ
After 6 years:
y = 1500(1.045)⁶ = 1953
The population of the island with growth rate of 4.5% per year and the current population is 1500 is 1953 after 6 years.

Answer:
y=6x-4
Step-by-step explanation:
First find the slope using the coordinates of (-1,-10) which will be your first pair x1 and y1. And (3,14) will be x2 and y2. To find the slope use this formula: m= y2-y1/x2-x1
Put the numbers of the coordinates in the formula and you get a fraction of
24/4 = 6 this is the slope
m=6
Then to find the y-int
Pick a coordinate they both will give the same answer. Put it into the point slope formula: y-y1=m(x-x1)
Only use y1, x1, and m which is 6 And solve
y-14=6(x-3) distribute the 6 this gives you
y-14=6x-18 to get y by itself, ADD 14 to both sides of the equal sign
Leaving you with y=6x-4
Answer:
844 m
Step-by-step explanation:
It is given that,
Grade 3 students used three rolls of ribbons measuring 300 metres, 286 metres and 258 metres for dance in primary Concert.
We need to find the total length of the ribbons. It means we can add all the lengths to find the total length of the ribbon. So,
Total length = 300 + 286 + 258
= 844 m
So, the total length of ribbons is 844 m.
