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>
Hi there
This is a smart question, so let me show you the trick of it.
176 feet per second
but we dont know per minute
We know that 60 seconds = 1 minute
with that information we can solve it
If 176 .......... 1 second
x .............. 60 second
x = 176 * 60
x= 10560
He is falling 10560 feet per minute
Sum of given complex numbers in polar form cos(pi/2) + i.sin(pi/2)
Complex number:
"The number of the type a + ib is called as complex number, where a, b are real numbers and 
What is polar form of the complex number?
"The polar form of a complex number z = x + iy
For given question,
The sum of given complex numbers would be w+z = 4cos(pi/2 + i sin(pi/2)+ 3 cos (3pi/2) + i sin(pi/2)
We know that:
cos(pi/2)= 0
sin(pi/2)=1
cos(3pi/2)=0
So, the sum of given complex numbers would be w+z:
=> 4cos(pi/2 + i sin(pi/2)+ 3 cos (3pi/2) + i sin(pi/2)
=> 4i + 3(-i)
= i
= 0+i
Therefore, the sum of given complex numbers in polar form as:
cos(pi/2) + i.sin(pi/2)

Answer:
3/8 < 7/16 is the only true answer
Step-by-step explanation:
Answer:
C. Equation
Step-by-step explanation:
An equation generally provides the most specific information about a function. However, it cannot always be used for certain purposes—such as finding a specific inverse function value.
In the case of equations that are infinite series, even evaluating the function can become difficult when the series converges slowly.
