The sum in sigma notation for the sequence will be as follows:
From
<span>5 + 10 + 15 + 20 + 25 + 30 + 35 + 40 + 45 + 50
first term=5
common difference=5
number of terms=10
n=nth term
thus the sum will be:
(i=2 to 10)</span>∑(5(n-1)+5)
Answer:
67.5cm^2
Step-by-step explanation:
area of a triangle is 0.5xaxb
Find all solutions for w by breaking the absolute value into the positive and negative components.
w = 7, -1
Hope this helps! :)
We shall have to use distribution here.
The number outside the parenthesis gets distribute with the numbers inside.
This is called distributive property.
We know the distributive property is
a(b+c) = a × b + a ×c
Using this property for
5(4 x+2)
= 5× 4x + 5 × 2
Now 5 times 4x = 20x
5 times 2 = 10
So we get
5(4 x+2) = 20 x + 10
Option A) is the right answer.
<span>Resistance is a force that B. Slows objects down. It is a force that opposes the motion of an object. This is why objects exerting an effort force must overcome the resistance force in order to do work. There are various types of resistance forces such as friction (ex. air resistance) and drag force.</span>
