write an equation through the points (-3,7) and (1,-1)​

Answers

Answer 1

The slope is -2.

The slope is the rise over the run. Because the line goes down from left to right, it makes the value negative. For every one the it moves to the right, the line goes down two units.

Which graph represents the function?

f(x)={3ifx<1xifx≥1

Answers

Answer: The graph in the bottom right corner.

Step-by-step explanation:

We have the function:

f(x) = 3   if  x <  1.

f(x) = x   if   x ≥ 1

First, let's analyze each part of the function:

f(x) = 3   if  x <  1.

We have a constant line y = 3, such that it ends at the point x = 1 with an open dot (or white dot) (because here we have the symbol <)

f(x) = x   if   x ≥ 1

From x = 1 and on, we have the line y = x, such that in the point x = 1 we will have a closed dot (or black dot) that means that the point does belong to the graph.

when x = 1, we have:

f(1) = 1

Then we will have the closed dot at the point (1, 1)

Then the correct option is the one in the bottom right.

Answer:

The answer is The graph on the bottom right

What is series ?

a series is a crude description of the operation of adding infinitely many quantities to a given initial amount one after the other.

A series is systematic way in which  numbers are arranged which are defined  by a particular function.

How to solve?

Given  views  pr day =5

everyday number of views double

hence series becomes=

[tex]=2^{0}*5+2^{1} *5+2^{2} * 5+2^3*5.....[/tex]

[tex]=5+2*5+4*5+8*5+16*5+32*5+64*5+128*5....[/tex]

now 640 people watch video

hence 640=128*5= day 8

Hence on day 8, 640 views are obtained.

Part 2 - To calculate for more than 20000 views one can apply GP FORMULA as the above series is geometric progression.

What function is the inverse of the exponential function y = 3^x?

Answers

Answer:

Step-by-step explanation:

First switch the y and x values:

[tex]x=3^y[/tex]

Take the natural log of both sides to get:

[tex]\ln(x)=y*\ln(3)[/tex]

Separate the y value:

[tex]y=\frac{\ln(x)}{\ln(3)}[/tex]

The inverse of the exponential function will be:

"y = [tex]\frac{ln(x)}{ln(3)}[/tex]".

Exponential function

According to the question,

The function, y = [tex]3^x[/tex]

By switching "x" and "y" of both sides of the function,

→     x = [tex]3^y[/tex]

Now,

By taking "log" both sides,

 ln(x) = y × ln(3)

By separating the terms, we get

      y = [tex]\frac{ln(x)}{ln(3)}[/tex]

Thus the above response is correct.

In ΔXYZ, ∠Y=90° and ∠X=16°. ∠ZWY=42° and XW=260. Find the length of ZY to the nearest integer. (9th grade honors geometry)

Answers

Step-by-step explanation:

[tex] \tan(16) = \frac{y}{260 + x} \\ (260 + x) \times \tan(16) = y \\ 74.55 + 0.286x = y \\ y = 0.286x + 74.55[/tex]

[tex] \tan(42) = \frac{y}{x} \\0.9 x = y[/tex]

[tex]0.9x = 0.286x + 74.55 \\ 0.614x = 74.55 \\ x = 121.42[/tex]

[tex]y = 0.9x \\ y = 109.27 = 109[/tex]

The length of ZY is [tex]109.27[/tex]

What is Trigonometry?

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies.

What is length?

Length is a measure of distance. In the International System of Quantities, length is a quantity with dimension distance. In most systems of measurement a base unit for length is chosen, from which all other units are derived. In the International System of Units system the base unit for length is the meter.

According to question, In ΔXYZ, ∠Y=90° and ∠X=16°. ∠ZWY=42° and XW=260.

We have to find the  the length of ZY.

Let the length of ZY be [tex]x[/tex] and WY be [tex]y[/tex]

From the given question and figure

[tex]tan16[/tex]°[tex]=\frac{y}{260+x}[/tex]

⇒[tex]tan16[/tex]°×[tex](260+x)=y[/tex]

⇒[tex]y=0.286x+74.55[/tex]

Now,[tex]tan42[/tex]°[tex]=\frac{y}{x}[/tex]

⇒[tex]y=0.9x[/tex]

From both the above equation,

[tex]0.9x=0.286x+74.55[/tex]

⇒[tex]x=121.42[/tex]

[tex]y=0.9x=109.27[/tex]

Hence, we can conclude that the length of ZY is [tex]109.27[/tex]
