Answer:
C. mass
Explanation:
Properties such as conductivity and density are usually normalized, so usually do not depend on sample size. While the amount of heat required to melt a sample will depend on its size, the actual melting point temperature does not.
Of the items on your list, "mass" is the one that depends on sample size. In fact, we usually describe the size of a sample in terms of its mass.
Answer:
sec(4x) + C
Explanation:
original problem: ∫sec(4x)tan(x)dx
use integration by substitution (u-sub) by setting u = 4x
if u = 4x, then du/dx = 4 and du = 4dx (dx = du/4)
after substitution the integral is ∫sec(u)tan(u)(du/4)
move the 1/4 out of the integral by using the integral Constant rule to form 1/4∫sec(u)tan(u)du
the anti-derivative of sec(u)tan(u) is sec(u), memorize your trigonometric derivatives!!!!
after integration, we get sec(u)/4 + C , now plug u back into the equation
sec(4x) + C is the general solution
It will cause a change in the quantity demanded. There will be the same demand, but if the price goes up less people will buy the papayas.
Answer:
Explanation:
14) Horrible English.
You can't have more than 2600 lbs on the elevator
or
You can have no more than 2600 lbs on the elevator.
"Can't have no more" is a double negative and quite confusing. It actually mean you Must have more than 2600 lbs on the elevator.
500 + 140x ≤ 2600
500 - 500 + 140x ≤ 2600 - 500
140x ≤ 2100
140x/140 ≤ 2100/140
x ≤ 15 people
15) $2.49(1.80) = $4.48
