Answer:
√53
Step-by-step explanation:
hypotenuse (h) = √89
base (b) = 6
perpendicular (p) = ?
we know by using Pythagoras theorem
p = √(h² - b²)
= √(√89)² - 6²
= √ 89 - 36
= √ 53
The quadratic equation f(x) = - x² + 3 · x + 13 evaluated at x = 10 is equal to - 57.
<h3>How to find the value associated with a quadratic equation</h3>
In this case we have a quadratic equation (f(x) = - x² + 3 · x + 13) that has to be evaluated at a value of x, that is, x = 10. Now we proceed to show the solution of the exercise step by step:
- x² + 3 · x + 13, x = 10 Given
- 10² + 3 · 10 + 13 Previous step
- 100 + 30 + 13 Definition of power / Definition of multiplication
- 57 Definition of addition and subtraction
The quadratic equation f(x) = - x² + 3 · x + 13 evaluated at x = 10 is equal to - 57.

Answer:
Question 1: B = 0
Question 2: 23/2 or 11-1/2
Question 3: 663/6 or 110-3/6
Step-by-step explanation:
Question 1:
(-5²)+(9+4²)=5B
-25+9+16=5B
5B=-0
B=0/5=0
Question 2:
2-7/8×2-6/9×1-1/2
=23/8×24/9×3/2
=23/2
=11-1/2
Question3:
3-1/4×6-2/3×5-1/10
=13/4×20/3×51/10
=663/6
=110-3/6
