Lynna [10]

Answer:

½ ln 3

Step-by-step explanation:

∫ sec²x / tan x dx

If u = tan x, then du = sec²x dx.

∫ du / u

ln|u| + C

ln|tan x| + C

Evaluate between π/4 and π/3.

ln|tan(π/3)| + C − (ln|tan(π/4)| + C)

ln|√3| + C − ln|1| − C

ln(√3)

NutritionCalc Plus uses the equations from the National Academy of Medicine to calculate the Estimated Energy Requirement (EER)
olga nikolaevna [1]

Answer:

The correct option is (A).

Step-by-step explanation:

The equation for the Estimated Energy Requirement (EER) of 19 or more years older men is:

EER = 662 - (9.53 \times AGE) + PA \times (15.91 \times WT + 539 \times HT)

Here,

AGE = age counted in years

PA = appropriate physical activity factor

WT = weight in kilograms

HT = height in meters

The physical activity factor for men and women is:

Activity Level       PA (men)      PA (Women)

Sedentary              1.00                1.00

    Low                    1.11                1.12

  Active                   1.25                1.27

Very Active              1.48                1.45

Given:

AGE = 22 year-old male college student

PA = low = 1.11

WT = 180 pounds = 81.6466 kg

HT = 5'10" = 1.778 m

Compute the value of EER as follows:

EER = 662 - (9.53 \times AGE) + PA \times (15.91 \times WT + 539 \times HT)

        = 662 - (9.53 \times 22) + 1.11 \times (15.91 \times 81.6466 + 539 \times 1.778)\\\\=662-209.66+1.11\times (1298.997406+958.342)\\\\=452.34+2505.64674066\\\\=2957.98674066\\\\\approx 2962

Thus, the EER for a 22-year-old male college student is approximately 2962 kcal.

The correct option is (A).

Write a parallel and perpendicular equation that passes through the point (6,-2)?
Reptile [31]

Answer:

y=x-8 and y=-x+4

Step-by-step explanation:

The slopes of the lines can be anything, as long as they are the opposite reciprocals of each other. Then you can plug in the point for x and y to solve for b in both lines (for y=mx+b where m is the slope)

An individual purchased 300 program licenses; 50 licenses will go to the satellite office out of state, and the remaining licens
laila [671]

Answer:We DO NOT HAVE ALL THE INFORMATION needed to solve for how many licenses each central office department will get.

Step-by-step explanation:

Now, if this very individual acquired about 300 program licenses and 50 licenses are taken or conveyed to the departments in the satellite office of the same organization, then the number of licenses that will be moved to the central office is:

300 - 50

= 250 licenses.

This implies that 250 licenses will be moved to the central office while 50 licenses will be kept/used at the satellite office.

Then, if there are eight (8) departments in the central office of this organization and 250 licenses will be evenly or equally distributed among the departments, each department will get:

250/8

= 31.25 licenses.

Since dividing 250 by 8 does not give a perfect integer, then there's an information we are yet to be furnished with. If 31 is multiplied by 8, it will give 248 which means that 2 licenses will be the remainder. If these 2 remaining licenses are shared equally between the 8 departments, one department will further get quarter of a license and we know licenses can't be shared or used in this manner.

Alternatively, of the 2 licenses remaining, two departments will have an extra license or one of the departments will have the 2 licenses which will now make the license distribution in the central office uneven.

So, we don't have all the information we need to solve for how many licenses each central office department will get.
