1=12.6cm; w=14.8cm; p=
1 answer:
We are given the length and width of a rectangle and we need to find perimeter- the distance around the shape
= 12.6 cm
w = 14.8 cm
The formula for the perimeter of a rectangle is
Perimeter = 2 + 2w
This makes sense because around the shape there are 2 equal lengths and 2 equal widths- one of the definitions of a rectangle
To find perimeter plug in the know vales of and w
Perimeter = 2(12.6 cm) + 2(14.8 cm)
Now use PEMDAS to solve
= 25.2 cm + 29.6 cm
= 54.8 cm
The perimeter of the rectangle is 54.8 cm

Answer:
The vertex of a quadratic equation corresponds to the point where the maximum or minimum value is located.
If the function has a positive leading coefficient, the vertex corresponds to the minimum value.
If it has a negative leading coefficient, the vertex corresponds to the maximum valuevalue
If the vertex is located at
(–2, 0)
The possibilities are
y = (x-2)^2
or,
y = - (x-2)^2
Since the problem tells us the answer, we adopt the positive values
Answer:
y = (x-2)^2

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.
