Solnce55 [7]3 years ago

6 0

Answer:

Step-by-step explanation:

multiply 12 times 6 which would give you 72, then the square root of 2 would be 4. So, multiply 1/4 times 4 which would give you 1. Add 72 + 1, and your answer is 73

Write a piecewise function for the graph.

Mariulka [41]

Similar to Modulus, but It's separated.

Since both are separated, that means - they are both linear function.

The range is greater than all negative numbers. That means y ≥ 0

( 1 ) For the blue graph,

y = -x-3 {y ≥ 0} ---------- Blue Graph Answer

-x-3=0

-x=3

x=-3

We can clearly see that the slope is -1.

And intercept x-axis at (-3,0)

( 2 ) For the red graph.

y = 2x+6 { y ≥ 0} ---------- Red Graph Answer

Notice that the slope is 2.

And intercept x-axis at (-3,0)

Also intercept y-axis at (0,6)

2x+6=0

2x=-6

x=-3

---------- Only linear function with given y ≥ 0 can draw that. (Only separated graph.) --------------

Convert the angle \theta=\dfrac{8\pi}{9}θ=

Nikolay [14]

Answer:

$160^\circ$ is the degrees value of $\theta = \dfrac{8 \pi}{9}$ .

Step-by-step explanation:

We are given the following details about the angle $\theta$ :

$\theta =\dfrac{8\pi}{9}\text{ radians}$

It is know that the relation between radians and degree units is as follows:

$\pi \text{ radians} = 180 ^\circ$

We can use simply use unitary method to convert radian value of $\theta$ to degrees.

$\pi \text{ radians} = 180 ^\circ$

$\Rightarrow 1 \text { radian}= \dfrac{\pi}{180} ^\circ$

$\Rightarrow \dfrac{8\pi}{9} \text{ radians} = \dfrac{180}{\pi} \times \dfrac{8\pi}{9} ^\circ\\\Rightarrow \dfrac{180 \times 8}{9}^\circ\\\Rightarrow 20 \times 8^\circ\\\Rightarrow 160 ^\circ$

Hence, $\theta = 160^\circ$

find the missing variable. if necessary, give the answer in simplest radical form. show your work. solve for question 3).a)

andrew11 [14]

Notice the picture below, the perpendicular line from the right-angle,
makes up 3 similar triangles, including the big one containing the small ones

so, you have three similar triangles, one large, a medium and a small one

now, using proportions for those folks, we end up with

$\bf \cfrac{\textit{large side}}{\textit{small side}}\qquad \cfrac{25}{x}=\cfrac{x}{9}
\\\\

\\\\
\cfrac{\textit{small side}}{\textit{medium side}}\qquad \cfrac{y}{16}=\cfrac{9}{y}
\\\\

\\\\
\cfrac{\textit{medium side}}{\textit{large side}}\qquad \cfrac{z}{25}=\cfrac{16}{z}$

solve for "x,y and z"
