Answer 1

Answer: (cos²Ф - 1) / sin Ф * 1/sin Ф=
1(cos²Ф-1) / (sin Ф* sinФ)=
(cos²Ф-1) / sin² Ф=

--------------------------------------------------------------
Fundamental relation of trigonometry:
sin²Ф + cos²Ф=1 ⇒ sin²Ф=1-cos²Ф ⇒-sin²Ф=cos²Ф-1
--------------------------------------------------------------

-sin²Ф/sin²Ф=1

Answer: (cos²Ф - 1) / sin Ф * 1/sin Ф=-1

Which of the following statements are true regarding functions? *Check all that applyA. The horizontal line test may be used to determine whether a function is one-to-one.

B. A function is a relation in which each value of the input variable is paired with exactly one value of the output variable.

C. The vertical line test may be used to determine whether a function is one-to-one.

D. A sequence is a function whose domain is the set of real numbers.

Answers

Answer: A and B.

C. FALSE, because the vertical line test may be used to determine whether a relation is the function.

D. FALSE, because the function domain can be any set.

Enter the values for a and b that complete

the sum:

3/x + 5/x^{2} =ax+b/x^{2}

Answers

ANSWER

a=3, b=5

EXPLANATION

The given equation is

$(3)/(x) + \frac{5}{ {x}^(2) } = \frac{ax + b}{ {x}^(2) }$

We simplify the left hand side.

We collect LCD to obtain:

$\frac{3x + 5}{ {x}^(2) } = \frac{ax + b}{ {x}^(2) }$

Both sides of the equation are now the same.

By comparing the coefficients of x, we have

$a = 3$

By comparing the constant terms

$b = 5$

Answer:

For the first part

A=3

B=5

For the second part

M=3

N=14

Answers

Answer:

C.11.2

Step-by-step explanation:

The distance between 2 points is given by

d = sqrt( (x2-x1)^2 + (y2-y1)^2)

= sqrt( ( -2-0)^2 + (-7-4)^2)

= sqrt( (-2)^2 + (-11)^2)

= sqrt( 4 + 121)

= sqrt(125)

= 11.18033989

A factory manufactures plastic bottles of 4 different sizes, 3 different colors, and 2 different shapes. How many different combinations are possible?

Answers

Multiply 4 sizes times 3 colors times 2 shapes because there would be actually 6 combinations of colors and shapes per size resulting in 24 combinations possible.

4*3*2=24

24, because to find the number of combinations, you multiply all of the different choices so you do 3x2x4 and that equals 24. Hope this helps! :)
