Hello,
Your question states:
Let f (x) = −x^2 − 5x + 36. What is the value of f(-3)?
Your answer would be:
42
Your explanation:

Answer:
Mean = 153
Median = 151.5
Mode = 159, 148, 138, 150, 165, 166, 145, 152, 155, 160, 147,
Step-by-step explanation:
Mean - add all numbers up (1820) then divide by 12
Median - put numbers in order, add two middle numbers and divide by 2
Mode - each number only came up once so they are all the mode
426,000 * 10^-4. You can go use a standard form calculator. and if you don't have a physical one, you can use one online.
Answer:
The three given points are the vertices of a right triangle.
Step-by-step explanation:
To determine that the three points are the vertices of a right triangle let us find the distance between each two points
The formula of the distance is
∵ = 6 and = -6
∵ = 9 and = -6
∴ =
∴ = 3
∵ = 6 and = -6
∵ = 9 and = 1
∴ =
∴ =
∵ = 9 and = 1
∵ = 9 and = -6
∴ =
∴ = 7
<em>Let us use the fact that if the square of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle at the vertex which opposite to the longest side</em>
∵ The longest side is
∵ The other two sides are 3 and 7
∵ ( )² = 58
∵ (3)² + (7)² = 9 + 49 = 58
∴ ( )² = (3)² + (7)²
- By using the fact above
∴ The triangle is a right triangle
The three given points are the vertices of a right triangle.
