Answer:
h= -28
Step-by-step explanation:
h+14=-14 isolate h by subtracting 14 on both sides
h= -28

Answer:
A
Step-by-step explanation:
a geometric sequence is where we multiply a factor from element to element.
a1 = $900
a2 = 981 = a1 × f = 900 ×
a3 = 1069.29 = a2 × f = a1 × f × f = s1 × f²
so, now let's try and get f.
remember, 981 = 900 × f
f = 981/900 = 109/100 = 1.09
just to control, we check for s3 :
900 × (1.09)² = 900 × 1.1881 = 1069.29
correct.
so,
a13 = 900 × (1.09)¹² = 2,531.398304
s13 is then the sum of all a1, ..., a13
there is a nice formula for sums of finite sequences
s13 = 900 × (1-f¹³) / (1-f) = 900×(1-(1.09)¹³) / (1-1.09) =
= 900×(1-3.065804612) / (-0.09) =
= 900×(-2.065804612) / (-0.09) = 20,658.04612
.
Answer:
A transitive property
Step-by-step explanation:
There isn't much to this.
This is the the transitive property.
I guess I can go through each choice and tell you what the property looks like or postulate.
A) If x=y and y=z, then x=z.
This is the exact form of your conditional.
x is AB here
y is BC here
z is DE here
B) Segment Addition Postulate
If A,B, and C are collinear with A and B as endpoints, then AB=AC+CB.
Your conditional said nothing about segment addition (no plus sign).
C) Distributive property is a(b+c)=ab+ac.
This can't be applied to any part of this. There is not even any parenthesis.
D) The symmetric property says if a=b then b=a.
There is two parts to our hypothesis where this is only part to the symmetric property for the hypothesis .
