Answer:
1. 16:32=1:2
2. 56:200=7:25
Step-by-step explanation:
1. 16:32=1:2 -> both divisible by 8
2. 56:200=7:25 -> both divisible by 8
Answer:
D) √15
Step-by-step explanation:
An irrational number is a number that can be expressed as an infinite decimal with no set of consecutive digits repeating itself indefinitely and that cannot be expressed as the quotient of two integers.
Therefore the answer would be D) √15 because the decimals keep going
A) 1.52 just ends like so
B) -13³ equals -2197
C) 9/4 equals 2.25
To find the case cube of a box in cubic feet, first measure its length, width, and height in inches. Next, multiply all 3 figures together, then divide the result by 1728 to get your case cube measurement in cubic feet.
Answer:
30
Step-by-step explanation:
Answer:
72.578 to the nearest thousandth.
Step-by-step explanation:
g(x)=3x^3 + 3x^2 - 30x + 24
Find the derivative:
g'(x) = 9x^2 + 6x - 30.
This equals zero for values of turning points:
9x^2 + 6x -30 = 0
3(3x^2 + 2x - 10) = 0
x = [-(2) +/- √(2^2 - 4*3*-10)] / 2*3
x = (-2 +/- √124) / 6
x = (-2 + 11.136)/6, (-2 - 11.136)/6
x = 1.523, -2.189.
To check which value of x gives a maximum value for f(x) use the second derivative test:
g"(x) = 18x + 6
when x = -2.189 g"(x) = 18(-2.189) + 2 which is negative so this value gives a local maximum.
Local maximum value for f(x)
= 3(-2.189)^3 + 3(-2.189)^2 - 30(-2.189) + 24
= 72.578 answer.
