I don’t understand what to do

Answer 1

Answer:

To use a unit circle, you must know where the coordinates are.

For this problem it is asking you where the sin(11pi/6) is.

You look at the unit circle for 11pi/6.

From here you look at the coordinates.

The x value is the cosine and the y value is the sine.

This means that the sin of 11pi/6 is -1/2.

To find the csc or the cosecant you just find 1/sin.

To find the the sec or secant you find 1/cos.

To find the tangent or tan you find the sin/cos.

And to find the cot or cotangent you find 1/tan.

Simplify -78 ÷ (-9)(Write answer as a mixed number: whole and fraction remaining.)

Answer:

8 2/3

Y-E-E-T

Step-by-step explanation:

-78 divded by (-9)

-78

-----

-9

there are negatives on both sides. I don't know how to explain that but you can change it to a PLUS.

78/9

divide 3 on both sides

78/3 =26

9/3=3

26/3 now.

so the mixed number would be 8 2/3

8 and 2/3

What is a fraction in math?

A fraction is a part of a whole. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator. In a simple fraction, both are integers. A complex fraction has a fraction in the numerator or denominator. In a proper fraction, the numerator is less than the denominator.

Given here: The proper fraction 5/6=0.83

Now 4/5=0.8

6/7=0.85

11/6=1.83

4/7=0.57

Thus 4/5 must lie between 5/6 & 1

Hence, The correct option is B) 1/5 as no other option lies in the required interval.

in order to solve it, we need find the zero of the polynomial.

we find the zero of the polynomial by splitting the middle term method

2x2 -+ 4x - 16

= 2x2 + 8x - 4x -16

= 2x( x + 4)- 4(x + 4)
= (2x-)(x+4)

we find the zeroes of the factors

experimentally we find two values, 2 and -4.

Thus, values of x are 2 and -4
