EXPLANATION
The line passes through these two points, 
and
.
We can use these two points to determine the slope of the line.
The formula for finding the slope of a line when at least two points are known is 
.
We can choose 
and 
or 
and 
.
We shall get the same result.
.
We now determine the equation of the line using the poit-slope formula,
.
When we choose , then we will obtain,
as the point-slope form.
When we choose , then we will obtain,
as the point-slope form.
There are a few ways to find out the correct answer. One of them is to divide 2.40 by 6 to get a price of one cake and then multiply it by 10:
2.40 ÷ 6 = 0.40
0.40 * 10 = 4.00
Answer: Ten cakes would cost 4 pounds.
D because I simplified it and got a quadratic formula which also simplified as the answer D
If all the dogs weighed the same, 44 would be the mean. The weight would be 44*5=220.
Hope this helped☺☺
Answer:
a) Explicit Formula : aₙ = 3. (-3)ⁿ⁻¹
b) Fifth term : a₅ = 243
Step-by-step explanation:
This sequence above is the Geometric sequence. The Geometric sequence is calculated using the formula
aₙ= a1.rⁿ⁻¹
where a1 = first term
r = common ratio
n = number of terms
From the above question, we are given
a1= 3, r=-3 and asked to find the explicit formula.
The explicit formula using the geometric sequence formula =
aₙ = 3. (-3)ⁿ⁻¹
b) The fifth term in the sequence is calculated as
aₙ = 3. (-3)ⁿ⁻¹
Where n = 5
a₅ = 3.(-3)⁵⁻¹
a₅ = 3.(-3)⁴
a₅= 243
