Answer:
The cross section of a pyramid that is perpendicular to the base will be a triangle.
Step-by-step explanation:
Answer:
1/4.
Step-by-step explanation:
I am assuming that there are 3 even and 3 odd tiles in each bag.
Probability( drawing an even tile form one bag) = 3/6 = 1/2.
The probability of drawing an even from the first and an even from the second = 1/2 * 1/2 = 1/4 (answer).
The individual probabilities are multiplied because the 2 events are independent.
1. (x - h)² + (y - k)² = r²
(x - (-10)) + (y - 6)² = 4²
(x + 10)² + (y - 6)² = 16
The equation of the circle is (x + 10)² + (y - 6)² = 16.
2. The answer is A.
3. The equation of the parabola is y = ⁻⁵/₃₆x² - 1²/₃x - 2.
4. I don't know the answer to the problem.
Answer:
B. (2, 4)
Explanation:
<u>Given equations</u>:
a) y = x + 2
b) y = 3x – 2
Solve them simultaneously:
x + 2 = 3x – 2
x - 3x = -2 - 2
-2x = -4
x = 2
Then find y = x + 2 = 2 + 2 = 4
Solution: (x, y) = (2, 4)
