As seen, the graph is pointing/increasing upwards. This means that the graph is exponentially increasing.
You notice there are significantly more spores at 4th hour than the first, therefore, this is an increasing trend.
Hope I helped :)
Answer:
Step-by-step explanation:
Given
Required
Determine the difference
Represent this with d.
d is calculated using
The equation becomes
Answer:
0,75kg : 18,38
4kg : 98
Step-by-step explanation:
1) 0,75 x 24,50 = 18,38
2) 4 x 24,50 = 98
Just fix the unit at the end. :)
XYA = (104 -52)/2
52 /2 = 26
the answer is 26 degrees
To get the points at which the two boats meet we need to find the equations that model their movement:
Boat A:
vertex form of the equation is given by:
f(x)=a(x-h)^2+k
where:
(h,k) is the vertex, thus plugging our values we shall have:
f(x)=a(x-0)^2+5
f(x)=ax^2+5
when x=-10, y=0 thus
0=100a+5
a=-1/20
thus the equation is:
f(x)=-1/20x^2+5
Boat B
slope=(4-0)/(10+10)=4/20=1/5
thus the equation is:
1/5(x-10)=y-4
y=1/5x+2
thus the points where they met will be at:
1/5x+2=-1/20x^2+5
solving for x we get:
x=-10 or x=6
when x=-10, y=0
when x=6, y=3.2
Answer is (6,3.2)
