The answer could be c or a
Use the slope formula which is y2-y1/x2-x1. -1-4/5-(-2)= -5/7
Answer:
a) h'(t)= (6cos3t,-9sin3t,3
cos3t)
b) t=0.93994736+πn/3
c) Magnitude of h(t) is 3 which is a constant, so h(t) lies on a sphere
Step-by-step explanation:
In Canada in 1998 the estimated number of households written in standard decimal notation is 3939000
<u>Solution:</u>
Given that in 1998 estimated number of households that owned 2 or more vehicles was 
Need to represent the number
in standard decimal notation.
In this case we need to move the decimal point based on the power of 10.
In our case power of 10 = 6.
Let’s first take a number without
and add six zeros on right.
So we get 3.939000000
Now multiplying above number by
means moving the decimal after 6 numbers from the current position, that means

That is 3939000 is required standard decimal notation of scientific notation number
