The variable z is directly proportional to x, and inversely proportional to y. when x is 16 and y is 17, z has the value 11.2941

Tresset [83]

Lets suppose k is the constant of proportionality.

z = k * x / y

when x is 16 and y is 17, z has the value 11.294117647059

11.294117647059 = k * 16/17

Multiplying 17 on both sides

11.294117647059 * 17 = k * 16

192 = k * 16

Dividing 16 on both sides

192/16 = k

k = 12

Now when x= 22, and y= 26

z = k * x/y

z = 12 * 22 / 26

z = 10.1538461538 : Answer

Hope it will help :)

Answer:

f(x) = $2^{(3x)}$

Step-by-step explanation:

The given options are,

a) f(x) = $2^{(3x)}$

b) f(x) = $({\frac {1}{2}})^{3x}$

c) f(x) = $2 \times ({\frac {1}{3}})^{x}$

d) f(x) = $\frac {1}{2} \times ({\frac {1}{3}})^{x}$

Now, among the given options only option (a) satisfies the criteria stated in the question i. e.,

1. f(x) → 0 as x → - ∞ and

2 f(0) = 1

so, the correct answer is,

f(x) = $2^{(3x)}$

What are the restrictions for (x^2+10x+25)/(x^2-3x-28) 0,14 -4,7 0,7 4,7

nirvana33 [79]

The answer is -4,7

The denominator can't equal zero. Factor the denominator:
x^2 - 3x - 28=
(X - 7)(x + 4); next set each set of parentheses equal to 0;
x - 7 = 0; so x=7 is one value
x + 4 = 0; so x=-4 is the other
Remember, x = 7 and x= -4 make the denominator zero, which is a "restriction" because you can't divide by zero.
