Answer:
-1/10
Step-by-step explanation:
3 x (-5)
-15
10 x (-9)
-90
-15/90 divided by 5
-3/30 divided by 3
-1/10
The common difference is 19-7 = 31-19 = 12, so this is an arithmetic sequence. The initial term (when n=1) is 7.
The explicit formula for the terms of an arithmetic sequence is
an = a1 + d(n-1)
where "a1" is the first term and "d" is the common difference. The formula that matches a1=7 and d=12 is
B. a(n) = 7+(n-1)·12
Fourths, then b. Sorry if late.
<span>Cost of maple syrup = $6.00 a Gallon
Cost of corn syrup = 0.80 cents a Gallon
Cost of the syrup mixture = $2.36 a Gallon
There is mixture of 50 Gallons
Lets maple syrup be x gallons, so corn syrup be 50-x gallons
Hence,
6*x + 0.80(50-x) = 2.36*50
6x + 40 - 0.8x = 118
5.2x = 78
=> x = 78/5.2 => x = 15
So Maple will be syrup be 15 gallons.
Corn syrup will be 35 gallons.</span>
Answer:
1) one
2) zero
Step-by-step explanation:
e/sinE = g/sinG
10/sin64 = 9/sinG
sinG = 0.8089146417
G = 53.99
j/sinJ = k/sinK
3/sin129 = 8/sinK
sinK = 2.072389241
