<u>Answer:</u>
Point Q lies on the circumference of the circle.
<u>Step-by-step explanation:</u>
We are given a circle with the point C (4,3) as its center with a radius of 3.16 units and we need to figure which of the given point lies on the circumference of the circle.
We can find this by using the distance formula:
Distance between C and P = 
Distance between C and Q = 
Distance between C and R = 
Since the distance between the points C and Q equals to the radius of the circle, therefore point Q lies on the circumference of the circle.
Answer: When you plug in an x-value into a function's derivative, the y-values you get back FROM THE DERIVATIVE tell you the slope of a tangent line to the original function at that value of x.
Step-by-step explanation:
Answer:
so required angles are 50.7°and 129.3°
Step-by-step explanation:
Let the angle be x
another angle = x + 78.6°
so,
x + x + 78.6° = 180° {being sum of supplementary angle}
so, 2x + 78.6° = 180°
or, 2x = 180° - 78.6°
or, x = 101.4/2
so, x = 50.7°
so another angle = x + 78.6°
= 50.7° + 78.6°
= 129.3°
Answer:
x=32
Step-by-step explanation:
Plug 10 into the second equation
10=1/2x-6
16=1/2x
16*2=x
x=32
1/15=8/x
x=8*15
x=120
The actual length of the dinosaur's tail is 120 in.
1/380=x/3420
3420/380=x
x=9
The height of this mountain on map would be 9 inches.
