Answer: 1

Step-by-step explanation:

Do what you see in the perentheses first wich is (13-8) 13-8= 5.

so you replace (13-8) -(14-10) like this

5-(14-10)=

then you do 14-10 wiche equals 4

replace the numbers

5-4= 1

so your answer is 1

The lograthmic function, lograthmic fu

$y=\log_4x$

To find:

a) Rewrite the function in exponential form.

b) For each given value of y, find the value of x to complete the ordered pair.

c) The graph of the function.

Explanation:

It is given that,

$y=\log_4x$

a) Since,

It is known that,

$\begin{gathered} y=\log_ax \\ \Rightarrow x=a^y \end{gathered}$

Then,

$x=4^y$

Hence, the exponential form of the function is,

$x=4^y$

b) Also,

For y = -2,.

The value of x is given by,

$\begin{gathered} \\ \Rightarrow x=4^{-2} \\ \Rightarrow x=\frac{1}{4^2} \\ \Rightarrow x=\frac{1}{16} \end{gathered}$

Hence, the ordered pair is (1/16, -2).

For y = -1,

$\begin{gathered} x=4^{-1} \\ x=\frac{1}{4} \end{gathered}$

Hence, the ordered pair is (1/4, -1).

For y = 0,

$\begin{gathered} x=4^0 \\ x=1 \end{gathered}$

Hence, the ordered pair is (1, 0).

For y = 1,

$\begin{gathered} x=4^1 \\ x=4 \end{gathered}$

Hence, the ordered pair is (4, 1).

For y = 2,

$\begin{gathered} x=4^2 \\ x=16 \end{gathered}$

Hence, the ordered pair is (16, 2).

c) Also, the graph of the given function is,

Can someone please help?!

Bond [772]

Answer:

1. $R_{90} (x,y)=(-y,x)$

2. $R_{180} (x,y)=(-x,-y)$

3. $R_{270} (x,y)=(y,-x)$ .

Step-by-step explanation:

Let us assume a point (x,y) in the co-ordinate plane on which the transformations will be applied.

Now, we know that 'rotation' is a transformation that turns that image to a certain degree about a point.

So, the given transformations gives us the forms as:

1. When we rotate an ( x,y ) by 90° about origin counter-clockwise, the resultant co-ordinate is ( -y,x ).

So, the function form is $R_{90} (x,y)=(-y,x)$ .

2. When we rotate an ( x,y ) by 180° about origin counter-clockwise, the resultant co-ordinate is ( -x,-y ).

So, the function form is $R_{180} (x,y)=(-x,-y)$ .

3. When we rotate an ( x,y ) by 270° about origin counter-clockwise, the resultant co-ordinate is ( y,-x ).

So, the function form is $R_{270} (x,y)=(y,-x)$ .

What is the value of the expression 10 + (fraction 1 over 2)4 ⋅ 48?

Rashid [163]

Answer:

i think you wrote the equation wrong because the answer is 106

Step-by-step explanation:

10+(1/2)4x48 solve using system of equations

multiplying is first (1/2)x4=2

10+2x48

multiply again 2x48=96

10+96=106

LuckyWell [14K]

Answer:

-5

Step-by-step explanation:

What is the slope of the line represented by the equation y = – – 5x

The equation of the line is given in slope-intercept form. The slope is simply the coefficient of x in the equation.

The slope of the line is thus -5
