56* cause alternate interiors angles
Answer:
if the measure of an angle is 90°, then the angle is a right angle.
Step-by-step explanation:
p=the measure of an angle is 90°
q=the angle is a right angle
p is the hypothesis of the conditional statement
q is the conclusion of the conditional statement
Given:
The vertex of a quadratic function is (4,-7).
To find:
The equation of the quadratic function.
Solution:
The vertex form of a quadratic function is:
...(i)
Where a is a constant and (h,k) is vertex.
The vertex is at point (4,-7).
Putting h=4 and k=-7 in (i), we get
The required equation of the quadratic function is where, a is a constant.
Putting a=1, we get
Therefore, the required quadratic function is .
1) this is total area of two triangle
area of a triangle=1/2*b*h
A=1/2*9*4
A=18 inches^2
multiply by 2 because there are two triangle with same measure
2A=2*18=36 inches^2
3) this is a area of rectangle and a triangle and then subtract
A2=9.3x7.8= 72.54
area of triangle A1=1/2*7.8 *3.3=12.87
A2-A1=59.69 mm^2
5) now u ca do it
Step-by-step explanation:
9 miles per day
8 days hiking
9m x 8d = 72 miles long
