What is the value of x

Colt1911 [192]

Answer:

The value of x are all real number on x-axis the number that falls under x

example of the value of x are in this equation

y=2+5x

2x+6y=60

to find x

let make the first one equation 1 and the second equation 2

now, put equation 1 in equation 2

2x+6(2+5x)=92

open the by multiplying every thing in the bracket by 6

2x+12+30x=92

combine the like terms

2x+30x=69212

32x=80

now divide via by 32

32x/32=80/32

x=5/2

Find the absolute minimum and absolute maximum values of f on the given interval. f(t) = 3 (*sqaure root sign*) t (20 − t), [0,

mafiozo [28]

9514 1404 393

Answer:

maximum: 15∛5 ≈ 25.6496392002
minimum: 0

Step-by-step explanation:

The minimum will be found at the ends of the interval, where f(t) = 0.

The maximum is found in the middle of the interval, where f'(t) = 0.

$f(t)=\sqrt[3]{t}(20-t)\\\\f'(t)=\dfrac{20-t}{3\sqrt[3]{t^2}}-\sqrt[3]{t}=\sqrt[3]{t}\left(\dfrac{4(5-t)}{3t}\right)$

This derivative is zero when the numerator is zero, at t=5. The function is a maximum at that point. The value there is ...

f(5) = (∛5)(20-5) = 15∛5

The absolute maximum on the interval is 15∛5 at t=5.

The answer is D. A translation does not change a figure's size or shape because each of its points are moved the same amount and in the same direction(s).
