A geometric sequence can always be expressed as:
a(n)=ar^(n-1), a=initial value, r=common ratio, n=term number
We are told that a(5)=25 and r=5 so we can say:
25=a5^(5-1)
25=a5^4
25=625a
a=1/25 so now we know our explicit formula for this geometric sequence:
a(n)=(1/25)(5^(n-1)) and the first three terms will be a(1), a(2), and a(3)
1/25, 1/5, 1
<span>k/-4 = - 0.8,
make k the subject of the equation by multiplying through by -4,
this means, </span><span>(k/-4) x -4 = - 0.8</span> x -4
this should give you k = -0.8 x -4, the negatives will cancel out to give you positive values,
so k= 3.2
your answer is D
Answer:
B. Leg-Acute (LA)
E. Angle-Angle-Side (AAS)
Step-by-step explanation:
Congruence is the relationship between two or more shapes with respect to their common properties.
Comparing the properties of triangles LMN and OPQ, it would be observed that two angles are similar and one side.
So that the congruence theorems or postulates required are:
B. Leg-Acute (LA)
E. Angle-Angle-Side (AAS)
Answer:
The correct option is e) $4.90
Step-by-step explanation:
Consider the provided information.
It is given that the Sales is $20.50 million
Operating costs excluding depreciation $12.60 million
Depreciation $3.00 million
Operating income (EBIT) = Net Earnings - Operating costs - Depreciation
Operating income (EBIT) = $20.50 - $12.60- $3.00
Operating income (EBIT) = $ 4.90
Hence, the correct option is e) $4.90
