An=a1(r)^(n-1)
an=5(-3)^(n-1)
so then each term is multiplied by -3
so
f(n)=-3(f(n-1))
and
f(n)=5
Answer:
350
Step-by-step explanation:
40% of 250 is 100 (10% of 250 is 25 and 25 times 4 is 100)
250+100 is 350
Answer : 44y. Put why because it’s repeated
<span>To write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. This is the value of m in the equation. Next, find the coordinates of the y -intercept--this should be of the form (0, b) . ... Therefore, the equation for this line is y = - x + 2 .</span>
Answer:
3.9 mi/h
Step-by-step explanation:
If the boy is rowing perpendicular to the current, the two vectors form a right triangle.
AB represents the downstream current, BC is the speed across the river, and AC is the ground speed of the boat
AC^2 = 2.4^2 + 3.1^2 =5.76 + 9.61 = 15.37
AC = sqrt(15.37) = 3.9 mi/h
The boat's speed over the ground is 3.9 mi/h.
