Answer:

Rounded to the nearest hundredths: 11.69.
Step-by-step explanation:
I would use the Pythagorean theorem for this problem.
The difference between the highest point and the lowest point of AD is 9.8-7.2 = 2.6, so that would be the height of the triangle. The length/base of the triangle would be 11.4.
Now, just solve using Pythagorean's theorem:

Rounded to the nearest hundredths: 11.69.

Answer:

2) 
Step-by-step explanation:
1) To write an Arithmetic Sequence, as an Explicit Term, is to write a general formula to find any term for this sequence following this pattern:

<em>"Write an explicit formula for each explicit formula A(n)=-1+(n-1)(-2)"</em>
This isn't quite clear. So, assuming you meant
Write an explicit formula for each term of this sequence A(n)=-1+(n-1)(-2)
As this A(n)=-1+(n-1)(-2) is already an Explicit Formula, since it is given the first term
the common difference
let's find some terms of this Sequence through this Explicit Formula:

2)
In this Arithmetic Sequence the common difference is 8, the first term value is 4.
Then, just plug in the first term and the common difference into the explicit formula:

Kappa

Answer:

Step-by-step explanation:
step 1
Alex’s printer
we know that
print 8 photos in 12 minutes
so
by proportion
Find how long will it take the printer to print 120 photos

step 2
Khalil’s printer
we know that
print 24 photos in 1 hour (60 minutes)
so
by proportion
Find how long will it take the printer to print 120 photos

step 3
Find the difference
