Answer:
A
Step-by-step explanation:
d(t)=3t+1 but d(t)=7
distance*time=3*time+1
so d(t)=7 is the same as
d(t)=3(2)+1
meaning that you hiked for 2 hours.
The probability of randomly picking one of those dishes is <span><span>8</span></span><span> out of </span><span><span>20</span></span><span>, or 8/20. We can simplify that down to 2/5. </span>
Step-by-step explanation:
using the formula :
2.d.s = V²-Vo²
2(-0.15) (60) = V² - (8.55)²
-18 = V² - 73.1
V² = 73.1 - 18
V² = 55.1
=> V = √55.1 = 7.4
so, the velocity when she ends the race =
7.4 m/s
Equation of a circle with center at (h,k) and radius of r is
(x-h)²+(y-k)²=r²
so
center (-7,10) and diameter 6
remember, diameter/2=radius=6/2=3
so
equation is (x-(-7))²+(y-10)²=3²
(x+7)²+(y-10)²=9
