Answer:
9
Step-by-step explanation:
let's assume ;
12=a
15=c
?=b
so;
a2+b2=c2
(12)2+b2=(15)2
144+b2=225
b2=225-144
b2=81 (square root both sides)
You'll get
b=9
NB; 2 is used as squared
Answer:
The correct answer is:
x ≤ 14 (b)
Step-by-step explanation:
first of all, let us find the other side of the rectangle using the limit of 46 as the highest perimeter:
Perimeter of a rectangle = 2(Length) + 2(width)
Let the length = x inches
let the width = 9 inches
Perimeter = 2x + 2(9)
46 = 2x + 18
2x = 46 - 18
2x = 28
x = 28 ÷ 2
x = 14
Therefore, for the perimeter to be equal to 46 inches, the other side of the rectangle must be equal to 14 inches. Hence, for the perimeter to be at most 46 inches ( 46 inches or less):
x is less than or equal to 14 (x ≤ 14)
Answer:
11/25
Step-by-step explanation:
15 red, 13 blue, and 50 total. Therefore, yellow = 50-15-13=22.
Probability (yellow) = 22/50 = 11/25
Answer:
The product rule is if the two "parts" of the function are being multiplied together, and the chain rule is if they are being composed. For instance, to find the derivative of f(x) = x² sin(x), you use the product rule, and to find the derivative of g(x) = sin(x²) you use the chain rule.
(sorry i didn't use the example but i hope this sort of helps!)
