What is the area of the triangle? 5 4 3 units?
1 answer:
Answer:
6 units squared
Step-by-step explanation:
Formula:
area = 0.25 * √( (a + b + c) * (-a + b + c) * (a - b + c) * (a + b - c) )
Assign variables:
A = 5, B = 4, C = 3.
Distribute:
area = 0.25 * √( (5 + 4 + 3) * (-5 + 4 + 3) * (5 - 4 + 3) * (5 + 4 - 3) )
Combine like terms
area = 0.25 * √( (12) * (2) * (4) * (6) )
Multiply:
area = 0.25 * √(576)
Square root:
area = 0.25 * 24
Multiply:
area = 6 units squared

Answer: The required exponential model is 
Step-by-step explanation:
Since we have given that
Initial cases = 1804
Rate of growth = 4%
Since it is increasing exponentially,
So, it becomes,
Here, a = 1804
b = 
So, it becomes,
Hence, the required exponential model is

Answer:
x = 2
y = -1
Step-by-step explanation:
y = 2x - 5
y = -2x + 3
2x - 5 = -2x + 3
4x = 8
x = 2
y = 2(2) - 5
y = -1
