Answer: Finding the area for a right triangle is really simple so I will just show you how too.
Step-by-step explanation:
I was taught that it was H × B ÷2 (make sure to use this formula on right triangles)
B=base
H=height
Its really similar to finding area of a rectangle but you just divide your answer by 2 at the end!
I hope that helps a bit.
(if you worried that you didn't do it correct I got 336 for number 1)
Answer:
<em>A.</em><em> There were 400 larvae at 0 degree Celsius.</em>
Step-by-step explanation:
Here,
x = the temperature of water in °C
y = the number of insect larvae in the water
The graph is a graph of quadratic function as it is a parabola and it opens downward, so it has a negative leading coefficient i.e coefficient of x² is negative.
At y intercept, the line or curve passes through y axis. At y intercept the value of x is zero, because on y axis the value of x is 0.
As the y intercept in this case is (0, 400), so at y intercept value of x is 0 and y is 400.
Therefore, at y intercept or at 0°C there were 400 larvae.
