Find the first 5 terms of the arithmetic sequence : a(1)=-3 , a(17)=-20

madreJ [45]

The explicit formula for arithmetic sequence is:
an=a+(n-1)d
where:
a=first term
d=common difference
given:
a3=22
a(17)=-20
substituting this in our equation we get:
22=a+(3-1)d
22=a+2d
a=22-2d........i

also:
-20=a+(17-1)d
-20=a+16d.....ii
but substituting i in ii we get:
-20=22-2d+16d
-20-22=14d
-42=14d
d=-3
but:
a=22-2d
a=22-2(-3)
a=28
thus the formula will be:
an=28-3(n-1)
thus the first term will be 28
the 2nd term will be:
a2=28-3(2-1)
a2=25

the 3rd term will be:
a3=28-3(3-1)
a3=28-6
a3=22

a4=28-3(4-1)
a4=28-9
a4=15

a5=28-3(5-1)
a5=28-3(4)
a5=28-12
a5=15

nikklg [1K]

The answer would be the distances that are not too large and not too small

A.legnth and width of a ball room
this would work because the next measurement is 1 mils and ball rooms are not that big

B. width of an eyelash. that is rediculously small so this is wrong

C. distanc from chicaco to san fransisco
way too far, use miles

D. height of a door
corect, door is apout 8 feet aprox

answer is A and D

Angelique draws triangle GHK. If A.1.2 or 5.7 B.2.2 or 4.7 C.4.7 D.5.7

The correct question in the attached figure

we know that

applying the law of sines
g/sinG=k/sinK

g=3 units
G=30°
k=4 units
K=?
so
g/sinG=k/sinK------> g*sinK=k*sinG-----> sinK=k*sinG/g
sinK=4*sin 30°/3-----> 2/3
K=arc sin(2/3)-------> K=41.81°

case 1)
for angle K=41.81°
the sum of the angles (H +G+K)=180°
H=180-(G+K)------> 180-(30+41.81)--------> H=108.19°

h/sinH=g/sinG-------> h=g*sinH/sinG------> h=3*sin 108.19°/sin 30°
h=5.70 units

case 2)
for angle K=180°-41.81°---------> K=138.19°
the sum of the angles (H +G+K)=180°
H=180-(G+K)------> 180-(30+138.19)--------> H=11.81°

h/sinH=g/sinG-------> h=g*sinH/sinG------> h=3*sin 11.81°/sin 30°
h=1.2 units

therefore

the answer is the option
A. 1.2 or 5.7
