Someone plz help answering this (mastery test)15points if u don’t know don’t answer real talk

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]

I think that you want to know how many total pounds of beans do you have.

Well, to find this, simply find the LCM of 6 and 4. That is 12.

So convert the fractions to have a denominator of 12.

10/12, 9/12

Now add:

(10+9)/12 = 19/12 = 1 7/12

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]".

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.

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

128 days and 4000 days

Step-by-step explanation:

Hence on day 8, 640 views are obtained.

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.

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.

Answer:

x = -3; substitute it to the other equation.

2(-3) - 7y = 30

-6 - 7y = 30

-7y = 30 + 6

-7y = 36

y = -36/7

we will not round the number because the question is asking for an improper fraction at its simplest form.

Answer:

5.1

Step-by-step explanation:

2*-3 - 7y =30

-6 + 7y = 30

7y = 30 + 6

y = 36 / 7
