Trig Function

100

What side of the right triangle is the opposite side to x^o?

3

200

What does TOA stand for?

Tan, opposite and adjacent

300

Set up the equation that you would use to solve for x.

cos(67)=95/x

400

Solve the angle. Round to the nearest tenths place.

x^o = 47.8

500

Write the three trig functions using 

 theta , opposite, adjacent and Hypotenuse 

sin(theta) = (opposite)/(hypotenuse)

cos(theta)=(adjacent)/(hypotenuse)

tan(theta)=(opposite)/(adjacent)

Function Transformation

100

What does the (h,k) represent?

Vertex

200

Identify the vertex: 

f(x)=(x-3)^2+5

Vertex: (3,5)

300

Identify the vertex: 

f(x)=-2(x+5)^2-8

Vertex: (-5,-8)

400

Identify the x-intercepts

 f(x)=(x-4)(x+7) 

(4,0) and (-7,0)

500

Identify the three forms of a function:

S

F

V

Standard form

Factored form 

Vertex form

Polynomials

100

Add the like terms together (2x^4+5x^3-4x) + (3x^4-4x^3+5) 

5x^4+x^3-4x+5

200

Can you add these two terms together? why or why not.

5x^2 and 3x?

You can NOT because the exponent are not the same.

300

Is (x-4) a factor of the following function.

f(x)= x^3-6x^2+5x+12

Yes it is a factor because the remainder is equal to zero.

400

DOUBLE POINTS

Use synthetic division to find the result when 

3x^3+16x^2+14x-8 

 is divided by (x+4) 

3x^2+4x-2

500

Identify all the possible roots of the following expression: 

3x^4-2x^3-6x^2+2x-8

(1,2,4,8)/(1,3) = 1,2,4,8, 1/3,2/3,4/3,8/3

100

Using the two way table find the following: 

What is the probability that a randomly selected person sleeps 6 hours or less?

P(6 hours or less) = 

7/21

200

Using the two way table find the following: 

What is the probability that a randomly selected person sleeps more than 6 hours and does not have an A?

P(more than 6 hours and does not have an A) = 

2/28

300

Using the two way table find the following: 

What is the probability that a randomly selected person sleeps more than 6 hours given they have an A.

P(6 or more|have an A) = 

5/20

400

Using the two way table find the following: 

What is the probability that a randomly selected person who failed the test, completed the homework?

P(complete hw|failed test) = 

6/9

500

What is the probability that a randomly selected person failed the test or completed the homework?

P(fail test or complete the hw) = 

16/18
