5/3 is the simplified slope.
Answer:
B and D
Step-by-step explanation:
A
× 13 = = = 10 < 13
B
4 × 13 = 52 > 13
C
× 13 = = = 4 < 13
D
× 13 = 1 × 13 = 13
Band D are equal to or greater than 13
The Pythagorean theorem applies to the sides of this right triangle.
... x² + (4/7)² = (5/7)²
... x² = 25/49 -16/49
... x = √(9/49)
... x = 3/7
The unknown side has length 3/7.
_____
You might recognize that this is a 3-4-5 right triangle with a scale factor of 1/7.
Easy peasy
A=20,000(1+0.13)^2
A=20,000(1.13)^2
A=20,000(1.2769)
A=25538
A is $25,538
7.75 and 45 are the variables in this equation
