Help!!

Mathematics
1 answer:
nika2105 [10]3 years ago
5 0

Answer:

AB←→

is a secant line.

Step-by-step explanation:

Not a chord because a chord ends and begins on a circular arch. (on the circle edge)

Cannot be a tangent line because a tangent line never touches the inside of a line.

Cannot be the diameter because a. it is always just inside the circle and I think it is the longest line (strait in the middle)

Can only be a secant line

In geometry, a secant of a curve is a line that intersects the curve at a minimum of two distinct points. The word secant comes from the Latin word secare, meaning to cut. In the case of a circle, a secant will intersect the circle at exactly two points.

PLEASE HELP ME The cost, C, to produce b baseball bats per day is modeled by the function C
AfilCa [17]
The minimum cost is the y-coordinate of the vertex of the parabola represented by the equation. The x-coordinate is the number of bats.

C(b)=0.06b^2-7.2b+390 \\ a=0.06 \\ b=-7.2 \\ \\
\hbox{the x-coordinate of the vertex: } \frac{-b}{2a}=\frac{-(-7.2)}{2 \times 0.06}=\frac{7.2}{0.12}=60


60 bats should be produced every day to keep costs at a minimum.

The number of question on an exam varies with the number
alekssr [168]

Answer:

t=5x

Step-by-step explanation:

So the number of questions in an exam varies with the number of minutes to take the exam.

For each question there are 5 minutes allotted.

Lets say that there are 'x' number of questions in the exam and 't' is the total time taken to finish the exam, in minutes. So the time taken to complete the exam would be

5 \times x=5x

Therefore, the equation relating the time taken to complete the exam and the number of questions is given by:

t=5x

So there are two variables in the equation, 't', and 'x':

t - time taken to complete the exam

x - number of questions on the exam

9 + 12n

Factorize it

3(3 +4n)

OR

The answer is the same.

Since we can't add a number with a number and letter. So in that case the answer is ;

9 + 12n.
