The correct question is
Using the graph of f(x) = log2x below, approximate the value of y in the equation 2^(2y) = 5
we have
2^(2y) = 5--------------> applying base 2 logarithm both members
2y*log2(2)=log2(5)
log2(2)=1
then
2y=log2(5)
y=[log2(5)]/2
using the graph
for x=5 the approximate value of log2(5) is 2.3
see the attached figure
so
y=[log2(5)]/2--------> y=[2.3]/2----------> y=1.15
the answer is
the approximate value of y is 1.15

Answer:
They must sell 106 more pizzas to earn $750.
Step-by-step explanation:
We are given that Mrs. Canale class is selling frozen pizzas to earn morning for a field trip. For every pizza sold, the class makes $5.35.
They have already earned $182.90, but they need $750. We have to find that how many more pizzas must they sell to be able to earn $750.
So, Firstly we will find that how much money did they have to earn more to be able to reach at $750.
Since, it is given that they have already earned $182.90.
So, Amount of more money they have to earn to reach at $750 = Final amount - Amount they already have
= $750 - $182.90 = $567.1
<em>That means they have to earn $567.1 more to be able to reach at $750 mark. </em>
Also, it is known that the price of every pizza sold = $5.35
So, Number of pizza that should be sold to earn an amount of $567.1 is given by;
<u>Number of pizzas</u> = =
= 106
Therefore, Mrs. Canale class must sell 106 more pizzas to be able to earn a total amount of $750.
