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

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.
