Answer:

10/3 or 3 1/3

Step-by-step explanation:

To solve this problem, we first combine our numbers which in this case are 5/2 which add to function f (x)

Now we have f(x) = -2/3(5/2) + 5.

= -10/6 +5

= -10+30/6

=20/6 = 10/3

= 3  1/3

To solve from here, we need to subtract 10 from the 30 of the equation. Whatever we do to one side,  we get 8.

Now we have f(5/2) = 10/3  or 3 1/3

This means that f(5/2) = 10/3  or 3 1/3

Answer:

3 1/3.

Step-by-step explanation:

f(5/2) = -2/3 * 5/2 + 5

= -10/6 + 5

= 5 - 5/3

= 10/3

= 3 1/3.

Use the polar representation to write the following in the form a + bi (a) (-1+ i)^7 (b) (1+v3i)^10
ira [324]

Answer with Step-by-step explanation:

For any complex number x+iy the polar form is represented as

z=re^{i\theta }

where

r^{2}=x^2+y^2\\\\tan(\theta )=\frac{y}{x}

Part a) x+iy = -1+i

Thus r=\sqrt{-1^2+1^2}=\sqrt{2}\\\\  \theta _{1}=tan^{-1}(\frac{-1}{1})=\frac{-\pi }{4}

Thus using De-Morvier's theorem

(-1+i)^7=(\sqrt{2}e^{i\frac{-\pi }{4}})^7\\\\\therefore (-1+i)^7=2^{7/2}\cdot e^{\frac{i-\pi }{28}}

Part 2) x+iy = 1+3i

Thus r=\sqrt{1^2+3^2}=\sqrt{10}\\\\  \theta _{1}=tan^{-1}(\frac{3}{1})=1.25

Thus using De-Morvier's theorem

(1+3i)^{10}=(\sqrt{10}e^{1.25i})^{10}\\\\\therefore (1+3i)^{10}=10^{5}\cdot e^{12.5i}

Using the graph of f(x) = log10x below, approximate the value of y in the equation 10^y = 3.
Tamiku [17]
Assuming log10x means log(base 10)x 

Let's rewrite 10^y = 3 by taking the log(base 10) of both sides
log (10^y) = log (3)                 Remember that log(10^y) = y
y = log (3) 
This is the same as our function f(x) = log(x), or f(3) = log(3)
Consult our graph of f(x) to find the y value at x=3
Checking the graph, we can find the value of y at point x=3
The value is .477. Therefore, y =.477, or about 1/2
