First, you need to remember how to obtain the answer.
1) (velocity)*(cosine of the angle)2)(velocity)*(sine of the angle)
Since the plane is traveling 45 degrees below the horizon the angle that we will be using is 180+45=225.
Therefore we will have,
150* cos(225) = -81.31
150*sin(225) = -81.31
*In the unit circle, the coordinates of 225 are -squareroot(2) divided by 2 for both sin and cos, which explains why we have the same answer for both sin and cos.
The answer being negative makes sense since the speed is decreasing due to the fact that the plane is traveling below horizontal.
Answer:
The radii of the circles are 12 cm and 7cm.
Step-by-step explanation:
Let the radii of the circles be 
Given:
Sum of circumference of two circles= 38π cm
Formula for circumference of a circle with radius r = 2πr
------------1
Sum of areas of two circles= 193π cm²
Area of circle with radius r = πr²
-------2
Substituting r2 = 19 - r1 in equation 2 we get:
Then r2 = 19 - r1
2m + n
2(10) + 8
the answer is 28
If the total number of lunch items is 117, there will be 39 hamburgers there
<h3>Ratio and proportion</h3>
Fractions are written as a ratio of two numbers
Given
Total items = 117
If the ratio of hot dogs to hamburgers is 26:13, then the total hamburgers that are there is given as:
Hamburgers = 13/39 * 117
Hamburgers = 39
This shows that if the total number of lunch items is 117, there will be 39 hamburgers there
