<u>Answer:</u>
square units
<u>Step-by-step explanation:</u>
Knowing the function and that the triangle is formed by both the x and y-axis, you already have the triangle's height, which is 10 (the y-intercept of the functon) To find the base length, all you have to do is find the x-intercept. To do that, simply:
Set function equal to 0 and solve for x:
f(x) = 10 - 
x
0 = 10 - x
x = 10
x = 
This means that the base length of the triangle is also . Now that you have the height and base length, you can
Plug values into the formula for the area of a triangle:
The area of a triangle is 
× height × base
Height = 10, base =
Area = × 10 ×
Area = 5 ×
Area =

Answer:
<u>There are 17 terms in the sequence</u>
Step-by-step explanation:
<u>Arithmetic Sequence
</u>
An arithmetic sequence is a list of numbers with a definite pattern by which each term is calculated by adding or subtracting a constant number called common difference to the previous term. If n is the number of the term, then:
Where an is the nth term, a1 is the first term, and r is the common difference.
In the problem at hand, we are given the first term a1=13, the last term an=-23, and the common difference r=-2 1/4. Let's solve the equation for n:
We need to express r as an improper or proper fraction:
Substituting:
n=17
There are 17 terms in the sequence
Answer:
Step-by-step explanation:
Putting value of n = 3 in equation
(3)2 + 3 + 5
9 + 8
= 17
