Multiply 3 x 7 = 51
Add 3 + 11 = 14
Then subtract 51 - 14 = 37

What is B^y=x in logarithmic form?

Gala2k [10]

Answer:

The logarithmic function for x = 2y is written as y = log2 x or f(x) = log2 x. The number 2 is still called the base. In general, y = logb x is read, “y equals log to the base b of x,” or more simply, “y equals log base b of x.” As with exponential functions, b > 0 and b ≠ 1

in 1990 there were about 5.4 billion people in the world. if the population has been growing at 1.95% per year, estimate the yea

kompoz [17]

Answer:

2011

Step-by-step explanation:

Here is the formula.

$A=P(1+r)^{n}$

A = Final Value

P = Starting Value

R = Rate

N = Time in Years

A = 8,000,000,000

P = 5,400,000,000

R = 0.0195

N = Time in Years

Solve for n.

20.35 Years from 1990; so sometime in 2011 the population would be 8 billion.

Answer:

(x,y,z) = (2,-2,1)

Step-by-step explanation:

Three equations with three variables are given. Take two equations at a time to eliminate one variable.

x + y - z = -1 .....(1)

4x -3y + 2z = 16 .....(2)

2x - 2y - 3z = 5 ......(3)

Solve (1) and (3) to eliminate z.

To do that multiply (1) by 2 and add (1) and (2). We get:

4x - 5z = 3 ......(4)

Now, solve (2) and (3) and subtract them. We get:

2x + 13z = 17 ......(5)

Solve (4) and (5). Multiply (5) by 2 and subtract. We get:

z = 1

Substituting z = 1, in (4) we get: x = 2.

Now to find y, substitute values of x and y in (1).

⇒ x + y - z = -1 ⇒ 2 + y - 1 = -1

⇒ y = -2

∴ Values of (x, y, z) = (2, -2, 1).
