Step-by-step explanation:
v=L×W×H
7×10×9=630cm3
We have that
3^y = 7
applying log both members
log(3^y)=log 7
y*log 3=log 7
y=log 7/log 3
using the <span>logarithmic graph of y=log x
</span><span>I graphically determine the values for x = 3 and x = 7
</span><span>
see the attached figure
for x=3
log 3=0.48
for x=7
log 7=0.85
therefore
</span>y=log 7/log 3-----> y=0.85/0.48-----> y=1.77
<span>
the answer isthe </span><span>
approximate value of y is 1.77</span>
For this case we have the following function:
The first thing you should do is graph the function to see the behavior.
When observing the graph (in the attached image) we observe that the following point belongs to the graph:
To prove it, let's evaluate the point in the function:
The equation is fulfilled and therefore the point belongs to the graph.
Answer:
(6.2, 7.4)

Answer:
Called a cylinder prism. It's volume = area of a cross section x length of prism
Step-by-step explanation:
Think of S as section and m as metric. and L as length
--------- --------- ---------
Sm^2 x L
Cross Section is 130m^2 and Length is 300m
Volume = 130 x 300 = 39000m^3
