Answer : The correct option is, (b) point.

Step-by-step explanation :

Line : In a geometry a line is straight (no bends). It extends in both the directions without end that means a line has no ends.

Line segment : It is a line that connects two points. It has definite end points.

Plane : It is a flat surface with no thickness. It extends forever.

Ray : It is a part of line that starts with point but no end point.

Point : It is an exact location that has no size, only position.

Hence, the in the symbol line AB the letter A represent a point.

Question 13

kicyunya [14]

Answer:

The c intercept is 42

The t intercepts are: 6, -1 and 7

Step-by-step explanation:

Given

$c(t) = (t - 6)(t +1)(t-7)$

Solving (a): The c intercept

Simply set t to 0

$c(t) = (t - 6)(t +1)(t-7)$

$c(0) = (0 - 6)(0 +1)(0-7)$

$c(0) = (- 6)(1)(-7)$

$c(0) = 42$

Solving (b): The t intercept

Simply set c(t) to 0

$c(t) = (t - 6)(t +1)(t-7)$

$(t - 6)(t +1)(t-7) = 0$

Split

$t - 6= 0,\ \ t +1= 0,\ \ t-7 = 0$

Solve for t

$t = 6,\ \ t =-1,\ \ t=7$

When factored completely, the expression p^4-81 is equivalent to what?

Mice21 [21]

Differnce of 2 pefect squares
a^2-b^2=(a-b)(a+b)
(p^2)^2-9^2=(p^2-9)(p^2+9)

p^2-9=(p-3)(p+3)

factored is
(p-3)(p+3)(p^2+9)

The interior angles formed by the sides of a quadrilateral have measures that sum to 360°.

stira [4]

The answer is 90 because 360/4 (since it is a quadrilateral) is 90 degrees
