3 km / h every second for 10 seconds = 30 km / hr
90 + 30 = 120 km / hr
Answer:
A
Step-by-step explanation:
We can write this as Sinx by "flipping" the
.
So we will have: 
From basic trigonometry, we know the value of
of sine is of the angle 
<em>But when is sine negative? </em>Either in 3rd or 4th quadrant. But the answer has to be between 0 and
, <em>so we disregard 4th quadrant.</em>
<em />
<em>To get the angle in 3rd quadrant, we add π to the acute angle of the first quadrant (which is π/4 in our case).</em><u><em> Thus we have:</em></u>

A is the right answer.
Answer:
Options (1) and (5)
Step-by-step explanation:
Expression that defines the function is,

Option 1





So,
is false.
Option 2
f(0) = 
= 
True.
Option 3
f(1) = 
= 
= 2
Therefore, f(1) = -1 is false.
Option 4



Therefore, f(2) = 1 is false.
Option 5
f(4)



True.
Options (1) and (5) are the correct options.

<em>Rounded to the nearest hundredth the volume of the composite figure is:</em>
<em>1308 33 cubic millimeters</em>
<h2>
Explanation:</h2>
Hello! I wrote the complete question in a comment above. The volume of a cylinder is defined as:

While the volume of half a sphere is:

Since we have 2 half spheres, then the volume of these is the same as the volume of a sphere:

Then, the composite figure is:

The radius of the cylinder is the same of the radius of each half sphere. So:
