Answer:
325
Step-by-step explanation:
You must have heard about Arithmetic Progressions (AP)
Arithmetic progressions are a series of numbers such that every successive number is the sum of a constant number and the previous number.
Our very own counting numbers form AP
For example :-
2 = 1 + <u>1</u>
3 = 2 + <u>1</u>
4 = 3 + <u>1</u>
The number in bold (1) is that constant number which is added to a number to form its successive number.
To find the sum of series forming AP, we use the formula :-
here,
- n is the number of terms
- a is the first number of the series
- an is the last number of the series
So we'll use all this information to find the sum of continuous numbers from 1 to 25 where 1 is the first term(a) and 25 is the last(an).
and n is 25
So, the value of S comes out to be 325.
Answer:
The answer is Parson's Market.
Step-by-step explanation:
First you want to find out how much one pound costs.
For Parson's you take 11.34 and divide it by 6.
11.34 / 6 = 1.89
Then you take how many pounds you are trying to get (7) and multiply it by the price per pound (1.89)
7 * 1.89 = 13.23
Ok, let’s take it step by step.
In order to write an equation in slope intercept form, solve for y.
3x+4y=12
First, subtract 3x from both sides.
4y=-3x+12
Now, divide both sides by 4.
y=-3/4x+3.
So, 3x+4y=12 written in slope intercept form is y=-3/4x+3.
To subtract vectors, subtract the x coordinates together. Do the same for the y coordinates as well.
In terms of a formula if we had the vectors u and v such that
u = <a,b>
v = <c,d>
then
u - v = <a-c, b-d>
Let's use that to get...
u - v = <6,-9> - <1,-4>
u - v = <6-1,-9-(-4)>
u - v = <6-1,-9+4>
u - v =
<5,-5>----------------------
Answer: A) <5,-5>
