24 questions correct

Step-by-step explanation:

.4×60 =24

24 questions.

Step-by-step explanation:

Total questions on the quiz = 60

% answered correctly = 40%

To know the amount answered correctly = 40% of 60

= 40/100 x 60

= 24.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
