The equation would be 0.05x + 3.15 = 5.10
0.05x = 1.95 (subtraction)
x = 39 (division)
39 minutes
we know that
In the right triangle RSQ
------> equation
In the right triangle RST
------> equation
equate equation and equation
therefore
the answer is
the length of SR is
Coordinates of Midpoint, knowing A(x₁, y₁) and B(x₂, y₂) is
x(of midpoint) = (x₁+x₂)÷2
y(of midpoint) = (y₁+y₂)÷2
Let A(4, -2) be one end point and B(x₂, y₂) , the other end point. Moreover the coordinate of the midpoint are given= M(1/2, 0)
1) x(of midpoint) = (x₁+x₂)÷2 = (4+x₂)÷2 , but x(of midpoint) = 1/2
Then 1/2 = (4+x₂)÷2 and x₂ = -3
2) y(of midpoint) = (y₁+y₂)÷2 = (-2+y₂)÷2 , but y(of midpoint) = 0
Then 0 = (-2+y₂)÷2 and y₂ = 2
Hence the pair of the other end is B(-3,2)
Answer:
Area = length × width
72 = 9 × width
8 = width (9 × 8 = 72)
pertinter = length + width + length + width
= 9 + 8 + 9 + 8
perimeter = 34
Answer:
The population size is 55.9597 (≅ 56)
Step-by-step explanation:
Since the population of protozoa develops at a constant growth rate of 0.4416 per member per day.
Then;
Day 0 = 3
Day 1 = 3 + (3 x 0.4416) = 4.3248
Day 2 = 4.3248 + (4.3248 x 0.4416) = 6.2346
Day 3 = 6.2346 + (6.2346 x 0.4416) = 8.9878
Day 4 = 8.9878 + (8.9878 x 0.4416) = 12.9568
Day 5 = 12.9568 + (12.9568 x 0.4416) = 18.6785
Day 6 = 18.6785 + (18.6785 x 0.4416) = 26.9269
Day 7 = 26.9269 + (26.9269 x 0.4416) = 38.8178
Day 8 = 38.8178 + (38.8178 x 0.4416) = 55.9597
After eight days, the population size would be 55.9597 (≅ 56).
