Answer: yes is it a function
Step-by-step explanation:
A graph is a function when there is only one y value for each x value. You can also use the vertical line test. This example is a “quadratic function”.
Answer:
n = 32 - 14 (= 18)
Step-by-step explanation:
You haven't given the answer options, however I assume it will be written in this form. I.e. the number of cupcakes still needed is just the total number of students (32) minus the number that Jenna bought (14).
so n = 32 -14 (=18)

<h3>Required Answer:</h3>
Shorter side = 9 cm
<h3>Question:</h3>
The perimeter of a rectangule is 44cm. The area of the rectangle is 117cm2. Find the length of the shorter side of the rectangle.
<h3>Let:</h3>
- Length rectangle be a.
- Width of rectangle be b.
<h3>To find?</h3>
- Length of the shorter side of the rectangle.
<h3>Given:</h3>
- Perimeter of rectangle = 44cm
- Area of rectangle = 117cm²
<h3>Answer :</h3>
A/Q
Perimeter of rectangle = 44cm
We know:
p=2(L+B)
.°. ⇒44 =2(a+b)
⇒44 /2 =a+b
⇒22=a+b
So:
a=22-b
b=22-a
Now Let's put values in formula of Area
A/Q
Area of rectangle = 117cm²
We know:
Area =L×B
.°.117=ab
<u>Put</u><u> </u><u>value</u><u> </u><u>of</u><u> </u><u>b</u><u> </u><u>in</u><u> </u><u>this</u><u> </u><u>equation</u><u> </u>
⇒117=a(22-a)
⇒117=22a-a²=0
⇒a-22a²+117=0
⇒(a- 9)(a- 13) = 0
.°. a=9
a=13cm
Let's put value of a as 13 to find b
⇒b=22-a
⇒b=22-13
⇒b=9cm
So the side having 9cm is shorter i.e. b
Answer
5,000
Explanation
1. Examine the number next to the thousands value (hundreds place)
2. Should that number be greater than 5, round the thousands value up one.
