49a. r=9 & r=3
49b. r=59048 & r=19683
49c. The first equation subtracts 1 from 3^n while the second equation subtracts 1 from the value of n.
49d. ***I forgot what an exponential function is, sorry...***
CANT FIGURE OUT 50. Hope I helped...
Answer:JKL and ∠RST are complementary.
m∠JKL = 36° and m∠RST = ( x + 15)°.
Find the value of x and the measure of ∠RST .
complementary angles are two angles whose sum is 90°
36%2Bx+%2B+15=90°
51%2Bx+=90°
x+=90-51°
x+=39°
->the measure of ∠RST== ( 39 + 15)=54°
both answer and explanation
The answer is true. Exterior Angle Theorem: The measurement of an exterior angle of a triangle is equal to the sum of the two remote interior angles. <span />
Answer:
Step-by-step explanation:
a1 = - 2
an = a1 * r^(n - 1)
a6 = -486
-486 = - 2 * r^(6-1) Divide by 2
243 = r^5
The largest value that r could be is 3.
4^5 = 1024
(243)^(1/5) = 3
So the general formula
an = -2*(3)^(n - 1)
Depends is the positive integer is larger than the negative interger for example -10+5=-5.
10+-4=6
