Mathematics

Contact [7]3 years ago
5 0

Answer:

Option 2). -4/3 is the correct answer

Step-by-step explanation:

It is given that,

sin Ø = - 4/5 and cos Ø>0.

sin Ø = opposite side/hypotenuse = - 4/5

Adjacent side = square root (hypotenuse² - opposite side²)

= square root (5² - 4²) = √9 = +3 or -3

cos Ø =Adjacent side/hypotenuse

It is given that, cos Ø>0

cos Ø = 3/5

Therefore  tan Ø = Opposite side/Adjacent side = 4/3 or -4/3

The second option is the correct answer -4/3

In a college of exactly 2920 students, exactly 55 % are male. What is the number of female students?
Annette [7]

Answer:

1305 female students

Step-by-step explanation:

Total no. of students = 2900

Percentage of students male = 55%

No. of students male = 55% of 2900

                                 = 55/100*2900

                                 = 1595

No. of female students = 2900 - 1595 = 1305

Find the partial derivatives indicated Assume the variables are restricted to a domain on which the function is defined. z=x8+3y
ahrayia [7]

Answer:

Step-by-step explanation:

The question is incomplete. Here is the complete question.

Find the partial derivatives indicated Assume the variables are restricted to a domain on which the function is defined. z=x^{8}+3^{y}+x^{y}

a) Zx b) Zy

In differentiation, if y = axⁿ, y' = nax^{n-1} \ where \ n\ is\ a\  constant. Applying this in question;

Given the function z = x⁸+3^{y}+x^{y}

Z_x = \frac{\delta z}{\delta x} = 8x^{7} + 0 + yx^{y-1} \\\frac{\delta z}{\delta x} = 8x^{7} + yx^{y-1} \\

Note that y is treated as a constant since we are to differentiate only with respect to x.

For Zy;

Z_y = \frac{\delta z}{\delta y} =0+ 3^{y} ln3 + x^{y}lnx \\\frac{\delta z}{\delta y} = 3^{y} ln3 + x^{y}lnx } \\

Here x is treated as a constant and differential of a constant is zero.
