HELP ME PLEASE ASAP!

Mathematics
1 answer:
givi [52]3 years ago
5 0

Answer:

x=28

Step-by-step explanation:

Usually triangles equal 180 so if that's the case then you just add all of the angles together and set it equal to 180. So your equation should be 50+ 2x+ 3x-10= 180 and then solve that equation and you will end up with x=28. Hope this helped!!

Explicit Formula

Just in case you don't know what this is, the explicit formula is the formula that solves for any term in the series without necessarily knowing what came before the term you are solving.

<em><u>Givens</u></em>

d = t_(n + 1) - t_n  You can take any term and the next term for this part of the formula

d = t_3 - t_2

t_3 = 1

t_2 = -7

d = 1 - - 7 = 8

a = -15

<em><u>Formula</u></em>

t_n = a + (n - 1)*d

t_n = -15 + (n - 1)*8

For example find the 5th term.

t_5 = - 15 + (5 - 1)*8

t_5 = - 15 + 4 *8

t_5 = -15 + 32

t_5 = 17  Which is what you have.

Recursive Formula

Computers really like this formula. They use it in what is called a subroutine and they pass values from one part of the program to a subroutine which evaluates the given and sends the result back. I'm telling you all this so you see why you are doing it. The disadvantage of it for humans is that you must know the preceding term to use the recursive formula.  

<em><u>Formula</u></em>

t_n = t_(n - 1) + d

<em><u>Example</u></em>

t_6 = t_(6 - 1) + d

t_6 = t_5 + 8

t_6 = 17 + 8

t_6 = 25

You can check this by using the explicit formula.

The graph of the step function g(x) = –⌊x⌋ + 3 is shown. What is the domain of g(x)? {x| x is a real number} {x| x is an integer
allsm [11]

Answer:

Option A is correct.

The domain of the g(x) is {x | x is a real number}

Step-by-step explanation:

The graph of the step function: g(x)=-\left \lfloor x \right \rfloor +3


Floor function is defined as the function that gives the highest integer less than or equal to x.

The graph of function: g(x)=-\left \lfloor x \right \rfloor +3  where x is the independent variable as shown below;

Domain of any function is the complete set of possible values of the independent variable

Therefore, the domain of the function g(x) is the set of all real numbers or we can represent this as  {x | x is a real number}.

Answer:

<h2>D</h2>

Step-by-step explanation:

If pair of ratios does form a true proportion then:

a:b=c:d\to\dfrac{a}{b}=\dfrac{c}{d}\to ad=bc

A)\\\\8:14=20:35\to\dfrac{8}{14}=\dfrac{20}{35}\\\\(8)(35)=(14)(25)\\\\280=280\qquad\bold{TRUE}\\\\b)\\\\\dfrac{6}{10}=\dfrac{15}{25}\\\\(6)(25)=(10)(15)\\\\150=150\qquad\bold{TRUE}

c)\\\\\dfrac{9}{5}=\dfrac{27}{15}\\\\(9)(15)=(5)(27)\\\\135=135\qquad\bold{TRUE}\\\\d)\\\\12:15=30:50\to\dfrac{12}{15}=\dfrac{30}{50}\\\\(12)(50)=(15)(30)\\\\600=450\qquad\bold{FALSE}
