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:

<h2><u>y = 1.16</u></h2>

Step-by-step explanation:

Take the natural logarithm of both sides of the equation to remove the variable from the exponent.

anygoal [31]

Answer:

1.  (x+8)(x-4)

2.  3x-20

Step-by-step explanation:

1.  x² + 4x – 32

x² + 8x - 4x - 32

x (x+8) - 4 (x+8)

one of the x+8's is cancelled out then you have (x+8)(x-4)

2.  x2 + x - 20​

2x+x-20

Use the discriminant of the following quadratic equation to state the number and type of solutions. 3x^(2)+4x-5=3x+2
krek1111 [17]
3x^(2)+4x-3x-5-2=0
3x^(2)+x-7=0
Discriminat= b^(2)-4ac= 1^(2)-4(3)(-7)= 1-12(-7)=1+84=85
The discrimination is bigger than 0 (delta>0) therefore there are 2 real solutions
