This is a geometric sequence, so use the formula for the sum of a geometric sequence:
Sum = (a(r^n - 1))/(r - 1)
where a is the first term, -5
r is the common ratio, 5
and n is the number of terms

Thus,
Sum = ((-5)(5^6 - 1))/(5-1) = -19530

In the diagram, AB = 10 and AC = 2/10. What is the
Mekhanik [1.2K]
Answer:
D.20 + 2/10 units

Step-by-step Explanation:
Perimeter is the distance all round a figure.
AB = 10. This is given in the question
AC = √((3-5)²+(4--2)²
= √(4+36)
=√40 = 6.32 units
BC = 5 - -5 = 10 units

Perimeter = AB+AC+BC
= 10+6.32+10
= 26.32 units
From the choices, we do not have an exact answer. The one that mosts suits the perimeter is 20 + units.

PLEASE HELP ME
Mila [183]

Answer:

(i)

time to bounce in one direction is 0.75 sec

(ii)

time to bounce in other direction is 1.5 sec

(iii)

total time is 2.25 sec

Step-by-step explanation:

Time to bounce in one direction:

we can see that height is increasing till t=0.75sec

so, time to bounce in one direction is 0.75 sec

Time to bound in other direction:

we can see that height is decreasing from t=0.75 to 2=2.25 sec

so, time to bounce in other direction is 2.25-0.75

=1.5 sec

Total time :

We know that

total time = (time to bounce in one direction)+(time to bounce in other direction)

now, we can plug values

total time =0.75+1.5=2.25 sec
