Given: "<span>B(t)=4*e^0.8t, How many hours will it take for the population to grow to 400?" Set B(t) = 400. Then:
400=4*e^(0.8t), or
100 = e^(0.8t)
Take the natural log of both sides, obtaining
ln 100
ln 100 = 0.8t. Then t = ----------- = 5.76 hours.
0.8</span>
Well we don't know the total of students so we divide 283 by 7.Which equals approximately to 41.
The
purple line is tangent. Tangent line intersects a circle in only 1 point
The
yellow dot is the point of tangency. It is the point where tangent line touches the circle
The
light blue line is secant. Secant line intersects a circle in 2 points
The
red line is the radius. Radius is the distance from center to the outer rim of the circle.
The
green line is the diameter. It is the line passing through the center of a circle. It measures twice the radius
The
gray line is the chord. Chord is the line whose endpoints lie on the circle.
Arc AB is a minor arc
Arc ABCD is a major arc
7x-5<13x-3
Minus 7x
-5<6x-3
then add 3
-2<6x
Then divide -2 by 6 and 6x by 6
-1/3>x
I think thats right
Answer:true
Explanation:
24+24=48
48-8=40
40x2=80
80=80!
So it is true.
