Answer:

30

Step-by-step explanation:

f(2) = f(2-1)*2

f(2) = 15 × 2 = 30

Answer:

f(2) =30

Step-by-step explanation:

f(1)=15

f(n)=f(n-1)*n

Put in n=2

f(2)=f(2-1)*2

     = f(1) *2

      = 15*2

       =30

The sum of 3 numbers is 131. the second of three numbers is seven more than twice the first. the third number is 12 less than th
arsen [322]
A+b+c = 131

b = 7 + 2a and c = a - 12
 so a + 7+2a + a-12 = 131
then 4a -5 = 131
then 4a = 136
and a = 34....so b= 75 and c = 22....check 34+75+22=131√

In the rho.bus, m angle 1 =4y-2. Find the value of y.
IRINA_888 [86]

Answer:

y = 23

Step-by-step explanation:

The diagonals of a rhombus are perpendicular bisectors of each other, thus

∠1 = 90° and ∠1 = 4y - 2, so equating gives

4y - 2 = 90 ( add 2 to both sides )

4y = 92 ( divide both sides by 4 )

y = 23

Question 4 options:
Arada [10]

Answer:

{ b, d, f }

Step-by-step explanation:

In the roster form we write the elements of a set by separating commas and enclose them within {} bracket.

We have give,

U = \{a, b, c, d, e, f, g\},

A = \{a, c, e, g\},

B = \{a, b, c, d\},

\because A' = U - A

\implies A' = \{a, b, c, d, e, f, g\} - \{a, c, e, g\}

= { b, d, f }
