We know that

<span>The measure of the external angle is the semi difference of the arcs that it covers.
so
see the picture attached to better understand the problem

m AB=128</span>°--------> by central angle
<span>m ACB=360</span>°-128°-----> m ACB=232°<span>
</span>∠x=(1/2)*[m ACB-m AB]<span>
</span>∠x=(1/2)*[232-128]-----> ∠x=(1/2)*104°-----> ∠x=52°
<span>
the answer is
</span>∠ x is 52°<span>
</span>

The relationship between numbers in list X and list Y follows the rule Y = X +2.05 what diagram shows this relationship
dexar [7]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

y=x+2.05

This is a linear equation ( equation of a line)

To graph the line find the intercepts

<u>The y-intercept</u> is the value of y when the value of x is equal to zero

For x=0

y=0+2.05=2.5

The y-intercept is the point (0,2.05)

<u>The x-intercept</u> is the value of x when the value of y is equal to zero

For y=0

0=x+2.05

x=-2.05

The x-intercept is the point (-2.05,0)

To graph the line plot the intercepts and then join the points

using  graphing tool

see the attached figure

Danielle earns a 8.25% commission on everything she sells at the electronics store where she works. She also earns a base salary
Otrada [13]

Lets begin with our y=mx+b, our constant(b) is 800 that she earns as a salary, our x represents the amount she sells, m then represents the commission which is 8.25% so converting that to a decimal and replacing it as m gets us y = 0.0825x+800. Replace $4500 for x and we have y=0.0825(4500)+800 solve and we get $1171.25

Which continent is estimated to have more than 5.31 billion people by 2050? To solve find what percent 5.31 is of billion is of
emmasim [6.3K]

The continent which has 59% of the total population will have more than 5.31 billion people by 2050.

<u>Step-by-step explanation:</u>

It is given that,

  • The total number of people is 9 billion.
  • The estimated number of people in 2050 year is 5.31 billion.

Therefore, you need to find out which continent has the estimated number by finding the percentage value.

<u>To find what percent 5.31 is of billion is of 9 billion :</u>

Let x be the percentage to be calculated.

⇒ x percent of 9 billion is 5.31 billion.

⇒ (x/100) × 9 = 5.31

⇒ x = (5.31 × 100) / 9

⇒ x = 531 / 9

⇒ x = 59 %

∴ The continent which has 59% of the total population will have more than 5.31 billion people by 2050.

What function is represented below?
Paladinen [302]
By graphing the given options as shown in attached figure
<span>f(x) = (1/4)^x+2   ⇒⇒⇒⇒ The black graph
f(x) = (1/4)^x +2  </span><span>⇒⇒⇒⇒ The red graph
</span> f(x) = (1/4)^x-2    <span><span>⇒⇒⇒⇒ The blue graph
</span></span><span><span /> f(x) = (1/4)^x -2   ⇒⇒⇒⇒ The green graph
</span>

The correct answer will be the blue graph

f(x) =   (\frac{1}{4})^{(x-2)}
