Simplify and write the trigonometric expression in terms of sine and cosine:
tan u + cot u = 1/f(u)

Answers

Answer:

we have the expression as;

1/sin u cos u

Step-by-step explanation:

tan u = sin u/cos u

cot u = cos u/sin u

Thus;

sin u/cos u + cos u/sin u

The lcm is sin u cos u

Thus, we have that;

(sin^2 u + cos^2 u)/sin u cos u

But ; sin^2 u + cos^2 u = 1

so we have ;

1/sin u cos u

The requested trigonometric expression in terms of sine and cosine is;

[tex]f(u) = \frac{1}{ \frac{sinu}{cosu} + \frac{cosu}{sinu} } [/tex]

Trigonometric expressions:

We must remember,

tan u = sin(u)/cos(u)

and cot u = cos(u)/sin(u).

Therefore we have;

sin(u)/cos(u) + cos(u)/sin(u) = 1/f(u)

By Cross-product; we have;

[tex]f(u) = \frac{1}{ \frac{sinu}{cosu} + \frac{cosu}{sinu} } [/tex]

Therefore, the required function, f(u) in terms of sin u and cos u is as represented above.

Answer:

The measure of angle 6 is 72.

The measure of angle 7 is 108.

Step-by-step explanation:

Corresponding angles are equal. So angle 1, 3, 5 and 7 are all equal.

If you look at angle 1 and 2, they are adjacent angles, so together they add up to 180. So if you subtract 108 from 180 you get 72... and we already established that all corresponding angles are equal, so if angle 2 is 72 degrees, we can conclude that angle 6 is as well.

Parallelogram R S T U is shown. Diagonals are drawn from point R to point T and from point U to point S and intersect at point V. The length of line segment U V is (x + 3) meters and the length of line segment V S is (2 x minus 7) meters. In parallelogram RSTU, what is SU? 10 m 13 m 23 m 26 m

Answers

Answer:

26m

Step-by-step explanation:

The diagonals of a parallelogram bisects each other. Hence the length of UV is equal to the length of VS

UV = VS

x+3 = 2x-7

x-2x = -7-3

-x = -10

x = 10

Get SU

SU = UV+VS

SU = x+3+2x-7

SU = 3x-4

Substitute x=10 into the expression

SU = 3(10)-4

SU = 30-4

SU = 26m

Length of SU is 26m

False

Step-by-step explanation:

It's actually C=πd d is diameter or C=πr^2

Answer:

True

Step-by-step explanation: Calculate circumference from area

We are given the area, and by substitution we know that 13π = πr2. We divide out the π and are left with 13 = r2. We take the square root of r to find that r = √13. We find the circumference of the circle with the formula C = 2πr.

100 POINTS PLEASE HELP I BEG YOU ONLY ANSWER IF YOU ANSWER ALL THE QUESTIONS

Answers

a) Maximum: 10

b) Minimum: - 2

To determine the amplitude we first recognize the midline, so I will answer part d first,

d) We have our maximum as 10, and our minimum as - 2. The midline, by it's name, is a line that divides the graph in half. What we do is determine the average of 10 and - 2 => 10 - 2/2 = 8/2 = 4

Midline: y = 4

Now I will go back to part c,

c) The amplitude would be 6. We take the difference between the maximum and the midline, or the minimum and the midline.

e) Period => The difference between two respective points on the graph

=> 3π/2 - π/2 = π, Period = π

f) We know that the period = π...

33 = x is a positive integer.
Work out the four possible values of x, writing your values in ascending order.

Answers

Answer:

Four possible values of x: 10, 3, 20, 31

Writing it in ascending order : 3, 10, 20, 31, 33

Step-by-step explanation:

Because x is a positive integers it means that x could be any number that goes from zero to infinity.

The possible values of x such that 33/x remains a positive integer in ascending order are 1,3,11 and 33.

What is an integer?

An integer is a whole number irrespective of the sign that the integer is all whole numbers that are going from 0 to infinite or 0 to minus infinite.

Integer ; ....-2 , -1 , 0 , 1 , 2 , .....

Given the expression, 33/x

Now positive integers are whole numbers ( 1,2,3,...)

To 33/x be the whole number and x is also a positive integer.

33/1 = 33 (1,3 Positive integer)

33/3 = 11 (3,11 Positive integer)

33/11 = 3 (11,3 Positive integer)

33/33 = 1 (33,1 Positive integer)

Hence "The possible values of x such that 33/x remains a positive integer in ascending order are 1,3,11 and 33".
