Which recursive formula can be used to generate the sequence shown, where f(1) = 5 and n > 1?

saveliy_v [14]

You can try them out and see which one works.

a: f(2) = f(1) +6 = 5+6 = 11 . . . . . . not this one

b: f(1) = f(2) -6 = -1-6 = -7 . . . . . . not this one (5 ≠ -7)

c: f(2) = f(1) - 6 = 5 - 6 = -1 . . . . . this gives the right f(2)

d: f(2 = -6(f(1) = -6(5) = -30 . . . . not this one

_____

The appropriate choice is ...

... f(n +1) = f(n) - 6

— — — — —

You can also recognize that the next term is 6 less than the current one, so f(n+1) = f(n) - 6, which corresponds to the 3rd selection.

Answer:

x=50

Step-by-step explanation:

Because these angles are vertical, they are equal. Let’s find x.

$3x+12=162$

$3x=150$

$x=50$

So, x=50.

A silversmith combined pure silver that cost $33.48 per ounce with 51 oz of a silver alloy that cost $24.35 per ounce. How many

Pavlova-9 [17]

Answer:

$38.31

Step-by-step explanation:

Given:

Pure silver that cost $33.48 per ounce used to form $24.35 alloy/ounce.

Question asked:

How many ounces of pure silver were used to make an alloy of silver costing $27.87 per ounce?

Solution:

At cost $24.35/ounce, pure silver is mixed = $33.48

At cost $1/ounce, pure silver is mixed = $\frac{33.48}{24.35}$

At cost $27.87/ounce, pure silver is mixed = $\frac{33.48}{24.35}$ $\times 27.87 = \frac{933.08}{24.35} = 38.31$

Thus, $38.31 ounces of pure silver were used to make an alloy of silver costing $27.87 per ounce.

Using v= u + at, find v, when u = 12, a = 5 and t = 7

aev [14]

Answer:

v = 47

Step-by-step explanation:

v = u + at

Plug in the values.

v = (12) + (5)(7)

Multiply 5 and 7.

v = 12 + 35

Add

v = 47

Hope this helps!
