Hi! If she reads 1/4 of a book each day, by the time three days have passed, she would have read 3/4 of the book because 1/4(3/1)=3/4. I hope this helps!

3 nights. 1/4 +1/4 +1/4 = 3/4. !/4 each night, and three 1/4ths, so three nights

-2 1/4÷(-3 1/3)=? Solve into a simplified proper or improper fraction.
schepotkina [342]

Answer:

The answer is

<h2>3/4</h2>

Step-by-step explanation:

-2 1/4÷(-3 1/3)

First convert the mixed number to an improper fraction

That's

- 2 \frac{1}{4}  =  -  \frac{9}{4}

And

- 3 \frac{1}{3}  =  -  \frac{9}{3}

So we have

-  \frac{9}{4}  \div   - \frac{9}{3}

Simplify

Change the division sign to multiplication sign and reverse the second number

That's

-  \frac{9}{4}  \times  -  \frac{3}{9}

Simplify

We have the final answer as

\frac{3}{4}

Hope this helps you

Convert the angle 5 radians to degrees, rounding to the nearest 10th.
lesya [120]

Step-by-step explanation:

\because {\pi}^{c}  = 180 \degree \\  \\  \therefore \:  {1}^{c}  =  \frac{180 \degree }{\pi}  \\  \\ \therefore \:  {5}^{c}  = 5 \times  \frac{180 \degree }{\pi} \\  \\ \therefore \:  {5}^{c}  = \frac{900 \degree }{\pi} \\  \\ \therefore \:  {5}^{c}  = \frac{900 \degree }{ \frac{22}{7} } \\  \\ \therefore \:  {5}^{c}  = \frac{900 \degree \times 7 }{22} \\  \\ \therefore \:  {5}^{c}  = \frac{6300}{22}  \\  \\ \therefore \:  {5}^{c}  = 286.363636\degree \\  \\  \\   \huge \red{ \boxed{\therefore \:  {5}^{c}  = 286.4\degree }}

Determine whether the degree of the function is even or odd and whether the function itself is even or odd.
Fynjy0 [20]

Answer:

There are Even, Odd and None of them and this does not depend on the degree but on the relation. An Even function: f(-x)=f(x) And Odd one: -f(x)=f(-x)

Step-by-step explanation:

1) Firstly let's remember the definition of Even and Odd function.

An Even function satisfies this relation:

f(-x)=f(x)

An Odd function satisfies that:

-f(x)=f(-x)

2) <u>Since no function has been given</u>. let's choose some nonlinear functions and test with respect to their degree:

f(x)=x^{2}-4, g(x)= x^{5}+x^{3}

f(x)=x^2 -4\Rightarrow f(-x)=(-x)^{2}-4\Rightarrow f(-x)=x^{2}-4\therefore f(x)=f(-x)

g(-x)=-(x^{5}+x^{3})\Rightarrow g(-x)=-x^{5}-x^{3}\Rightarrow g(-x)=-g(x)

3) Then these functions are respectively even and odd, because they passed on the test for even and odd functions namely, f(-x)=f(x) and -f(x)=f(x) for odd functions.

Since we need to have symmetry to y axis to Even functions, and Symmetry to Odd functions, and moreover, there are cases of not even or odd functions we must test each one case by case.
