Answer:
- Discontinuity at (-1,6)
- The zero is at (-7,0)
Step-by-step explanation:
Given the function , you need to factor the numerator. Find two number whose sum be 8 and whose product be 7. These are 1 and 7, then:
Then, the denominator is zero when
Therefore, does not belong to the Domain of the function. Then, (-1,6) is a discontinuity point.
Simplifying, you get:
You can observe that a linear function is obtained.
This function is equal to zero when , therefore the zero of the function is at (-7,0).
Answer:
None
Step-by-step explanation:
Parallel lines never intercept, giving no solution points
The altitude is the mean proportional between the left and right parts of the hyptenuse
20/m = m/8
m² = 20 · 8
m² = 160
m = √160
m = 4√10
The area of any triangle is
(1/2) · (base · height) .
As soon as you know the base and the height, simply
write them into that formula to calculate the area.
A square can be classified as a rhombus, Square, Rectangle, quadrilateral, and parallelogram.
quadrilateral - 4 sides - 4 angles.
parallelogram - 2 pairs of parallel sides.
It is a rhombus - 4 congruent length sides and 2 pairs of parallel sides.
square- 4 sides- 4 congruent sides- 2 sets of parallel sides- 4 right angles
rectangle - 2 sets of parallel sides- 4 sides- 4 right angles- 2 different sets of congruent sides
*note* although a square can be a rectangle a rectangle can't be a square
