F(6)= 2*(6^2) +5 *sqrt(6-2) = 2*36+ 5*sqrt(4) = 72 +5*2 =72+10 =82
In the US, a pint is 16 fluid ounces and a quart is 2 pints. So, every quart will fill 2 coffee mugs.
Annie needs to fill 26 mugs, and she needs 1 quart for every 2 mugs. So Annie needs 13 quarts of coffee total.
Answer: f(x)=200•(0.85)^x
Step-by-step explanation:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the decaying rate, expressed in decimal
Depreciation is often modeled as an exponential decay function. Since Jim bought a skateboard for Co=$200, its value will depreciate by r=15% = 0.15 each year since buying it.
CommentThe measurement of an arc in degrees is the same as the central angle. We must assume that the central angle is the measurement given.
= 49
To find the next one you need to find the measurement from B to C, the arc that is over 180 degrees. Maybe you could put another letter between B and C so that we could refer to that top arc greater than 180 degrees. Call the point you inserted D.
= 360 - 49 - 107 = 204
=
+
Arc(
ABC) = 204 + 49 = 253
Arc(
BAC) = Arc(BC) + Arc(AB)
Arc(
BAC) = 107 + 49
Arc(
BAC) = 156
Arc(
ACB) = 107 + 204 = 311
