Answer:
see below PLEASE GIVE BRAINLIEST
Step-by-step explanation:
HOUSE - LIBRARY = 1 3/5 MILES
LIBRARY - MALL - KYLE'S HOUSE = 1 1/3 + 4/5 = 4/3 + 4/5 =
20/15 + 12/15 = 32/15 = 2 2/15 miles
2.1 x 82 =
172.2
I hope this answer was helpful! :)
The answer will be arithmetic sequence!
D.
first, eliminate B and C, because the highest degree in these two equation is 3, a 3-degree equation has 3 roots, not 4.
between A and D, A has the roots 0, 0, 7, and -7, all real roots.
D can be factored into (x²-49)(x²+1)=0
x²=49 or x²=-1
x=7 or -7, x=i or -i two real roots, two unreal roots
for the second equation:
first, find the first term by using the formula:
the nth term=the first term + (n-1)*difference
you are given the 13th term and d=3.7
a13=a1+(13-1)d
1.9=a1+12*3.7
a1=-42.5
the sum of the first 13 terms is S=(a1+a13)*(13/2)=(-42.5+1.9)*6.5=-263.9
