We have to use rounding or compatible numbers to estimate the difference of 823 and 242.
Since, a quick way to estimate the difference between two numbers is to round each number and then subtract the rounded numbers.
Therefore, rounding the number 823 to the nearest tens = 820
Rounding the number 242 to the nearest tens = 240
The difference between the estimated numbers
= 820 - 240
= 580
Therefore, the estimated difference is 580.
Answer:
7 cm
Step-by-step explanation:
base area = (base length x base height)/2 = (2x6)/2 = 6 cm^2
height = V / base area = 42 / 6 = 7 cm
I would say 2/5 chance since 1 is neither prime or composite
Given the functions
(a) f(x) = x³ + 5x² + x
(b) f(x) = x² + x
(c) f(x) = -x
Function (a)
f(-x) = (-x)³ + 5(-x)² + (-x)
= -x³ + 5x² - x
= -(x³ - 5x² + x)
The function is neither even nor odd.
Function (b)
f(-x) = (-x)² + (-x)
= -(-x² + x)
The function is neither even nor odd.
Function (c)
f(-x) = -(-x)
= x
= -f(x)
Because f(-x) = -f(x) the function is odd.
Answer: f(x) = -x is an odd function.
Answer:
C
Step-by-step explanation:
Use the pythagorean theorom
a^2 + b^2 = C^2
convert so it goes to the problem
c^2 - a^2 =b^2
10^2 - 5^ = 100 - 25 = 75
srt. 75 = 5 sqrt.3
