Answer:
What do you need help with?
Step-by-step explanation:
Answer:
1) Arithmetic since it decreases by 3 so, -3n + 38.
2) Arithmetic since it decreases by 20 each time, so -20n+17
Step-by-step explanation:
Answer:
Y=3x+5
Step-by-step explanation:
If we take x = 1, according to the first function (the answer) y would be 8.
Other options:
—————
Formula 3:
Y= 2^x+5 == 7
Formula 4:
Y = x+8 == 9
True answer = 10.
——————
Ok, so the last one seems more accurate lets test the first and last one on two more numbers:
——————
X = 15
Formula 1:
50
Formula 4:
23
True answer = 60.
The first formula wins.
————————-
X= 10
Formula 1:
35
Formula 4:
18
True answer = 41
The first formula wins.
——————
So, we can see that the first formula is most accurate.
Answer:
Given the information above, the area of the square is 361 cm²
Step-by-step explanation:
A square is a shape with four equal sides. So, in order to find the area of the square, we must find the length of each individual side. We can do this by dividing the perimeter by 4 because a square has 4 equal sides meaning they have the same lengths.
The perimeter of the square is 76. So, let's divide 76 by 4.
76 ÷ 4 = 19
So, the lengths of each sides in the square is 19cm.
In order to find the area, we must multiply the length and the width together. Since a square has equal sides, then we will multiply 19 by 19 to get the area.
19 × 19 = 361
So, the area of the square is 361 cm²
Choice D will create an irrational number when added. This is because a rational number plus a rational number will always be irrational (you can experiment this by trying to add rational numbers to pi). For example, 3 + pi = 6.1415926..... or
