Answer:
D
Step-by-step explanation:
means the inverse. The inverse is the function reflected over the y=x line. This means the values have been reversed. (x,y)-->(y,x). We are looking for a point that has reversed values from the table.
The table has (1.-5) so the inverse is (-5,1) or D.
Answer: 10 inches.
Step-by-step explanation:
We have to solve a system of equations.
The formula to calculate a triangle area is A = (b.h)/2
where b is the base and h is the height. This will be our first equation.
Since the height is 4 inches greater than the base, the second equation will be: h = b+4
We replace h and the value of the area (70 square inches) in the first equation, and we solve it by using the cuadratic equation formula:
70 = (b . (b+4)) / 2
70 . 2 = b² + 4b
140 = b² +4b
0 = b² + 4b - 140
The roots of this polynomial are -14 and 10. Since a distance can't be negative, the length of the base is 10 inches.
The general form for Pythagoras' theorem is: a² + b² = c² (where c is the longest side).
You already have sides a and b, and to figure out c, you just have to substitute the numbers into the original equation and work it out step by step. Let's substitute a for 17 and b for 24:
a² + b² = c²
(17)² + (24)² = c²
289 + 576 = c²
865 = c²
Square root both sides to work out c:
√865 = √(c²)
c = √865 ≈ 29.41
