Please solve last question on test 1/2 - 1/8q=q-1/4
omeli [17]

Answer:

 q = 2/3

Step-by-step explanation:

From the question the equation is given by,

                      1/2 - 1/8q=q-1/4

Rearranging the terms in the given equation and bringing the similar terms to the same side of the equation,

                    - 1/8q -q = -1/4 - 1/2

Adding the terms in the equation of both left and right hand side of equation:

                    -((1+8)/8) × q    = -(1+2)/4

                    -(9/8) × q         = -3/4

Dividing the both sides of the equation by  3/4

                    -3/2q               = -1

Multiplying the both sides of the equation by -2/3

Therefore,              q=2/3

The function f(t) = 1100(0.9945)^t represents the change in a quantity over t weeks. What does the constant 0.9945 reveal about
TEA [102]

Answer:

As t increases, the quantity reduces

Step-by-step explanation:

Given

f(t) = 1100(0.9945)^t

Required

What does the rate (0.9945) reveal about the function

From the given function, the rate b is:

b = 0.9945

When b has the following range:

0

Then, it means there is a reduction

<em>In other words, as the number of weeks (t) increases, the quantity (f(t)) reduces</em>

Find the indicated limit, if it exists. (1 point) limit of f of x as x approaches 9 where f of x equals x plus 9 when x is less
Sunny_sXe [5.5K]

Answer:

Step-by-step explanation:

For the limit of a function to exist, then the right hand limit of the function must be equal to its left hand limit as shown;

If the function is f(x), for f(x) to exist then;

\lim_{n \to a^{+} } f(x) =  \lim_{n \to a^{-} } f(x) =  \lim_{n \to a } f(x)

Given the function;

f(x) = \left \{ {{x+9\ x

Lets check if the above statement is true.

The right hand limit of the function occurs at x> 9

f(x) = 9-x

\lim_{x \to 9+} (9-x)\\= 9-9\\= 0

The left hand limit occurs at x<9

f(x) = x+9

\lim_{x \to 9^{-} } (x+9)\\= 9+9\\= 18

From the above calculation, it can be seen that \lim_{x \to 9^{+} } f(x) \neq   \lim_{x \to 9^{-} } f(x), this shows that the function given does not exist at the given point.
