BartSMP [9]
24.75= 2.25y - 22.95
+22.95 +22.95
47.7 = 2.25y (division here)
2.25 2.25

HELP i know this is simple but i cant seem to find the correct equation

<h3>Answer:  g(x) = (-2/3)*x^2</h3>

============================================

Work Shown:

f(x) = x^2

g(x) = a*f(x) for some constant 'a' since g(x) is a scaled version of f(x).

The value of 'a' vertically stretches f(x) upward if a > 0

If 'a' is negative, then we have a reflection going on as shown in the diagram.

We want (x,y) = (3,-6) to be on the graph of g(x). This means g(3) = -6

If we plugged x = 3 into f(x), we get

f(x) = x^2

f(3) = 3^2

f(3) = 9

So,

g(x) = a*f(x)

g(3) = a*f(3) ... replace x with 3

g(3) = a*9 ... replace f(3) with 9 since f(3) = 9

-6 = a*9 ... replace g(3) with -6 since g(-3) = -6

9a = -6

a = -6/9

a = -2/3

Therefore, this means

g(x) = a*f(x)

g(x) = (-2/3)*f(x)

g(x) = (-2/3)*x^2

DedPeter [7]

Answer:

the probability that a box weighs exactly 31 ounces is 0

Step-by-step explanation:

since the box has a continuous distribution (therefore there are infinite real numbers between 31.8 and 32.6 ounces) , the probability of a exact value out of a infinite quantity is 0  . Mathematically , since the probability for a random variable X to be between values of 'a' and 'b' for a continuous probability density function f(x) is

P(a≤X≤b)=∫ₐᵇ f(x) dx  

for b=a, then

P(X=a)= ∫ₐᵃ f(x) dx = 0

Nevertheless , since the value of 31 is outside the range of 31.8 and 32.6 ounces, the probability of a value outside the continuous distribution is also 0
