c) $26 \leq w \leq 42$

d) Weight above 42 pounds, so she cannot.

Step-by-step explanation:

a. What is the margin of error?

Within 8 pounds, so margin of error of 8 pounds.

b. Express the acceptable weights as an interval.

34 - 8 = 26

34 + 8 = 42

[26,42]

c. Write an expression in the format to represent the interval.

$26 \leq w \leq 42$

B) y = log2 (4" - 4) find the inverse of this equation

GuDViN [60]

Answer:

$y = \frac{1}{4} \times {2}^{x} - 1$

Step-by-step explanation:

Assuming the given logarithmic equation is

$y = \log_{2}( {4}{x } - 4)$

We interchange x and y to get:

$x= \log_{2}( {4}{y} - 4)$

We solve for y now:

${2}^{x} = {4}{y} - 4$

We add 4 to both sides to get;

${2}^{x} + 4 = 4y$

Divide through by 4:

$y = \frac{1}{4} \times {2}^{x} - 1$
