You are riding the bus to school and you realize it is taking longer because of all the stops you are making. The time it takes
Sedaia [141]

Answer:

7 minutes

Step-by-step explanation:

If x represents the number of stops, and there are 2 stops after you board, solving g(2) will give you the time it takes to get to school allowing time for x = 2 stops:

g(2)=(2)^4-3(2)^2+4(2)-5

This gives you, in minutes, that

g(2) = 7

A circle has its center at the center of a square with 26-inch sides. Using 3.14 for pi, find the area of the square not covered
AlladinOne [14]
For squrae
area=side²
perimiter=4(side)

for circle
area=pir²
circumference=2pir

side=diameter, diameter/2=radius=side/2


find area not covered
that is areasquare-areacircle
areasquare=26²=676 sqauare inches
areaciecle, diameter=side, 26/2=13, area=pi13²=169*3.14=530.66 square inches

areanotcovered=676-530.66=145.34 square inches not coverd


ratio of perimiter to circumferece
perimiter=4*26=104
circumference=2pir=2pi13=26pi=26*3.14=81.64
circumference to perimiter is 81.64/104=0.785
