Answer:

105°

Step-by-step explanation:

From the picture, C is the center of the circle.

The chord that passes the center is called a diameter.

Angle x is a central angle which corresponds to the arc of it. So therefore the measure of the arc would be the same as the measure of that corresponding <em>central angle </em>and vice versa.

So if m arc BF = 105°, then x° = 105°

Construct a linear equation for the linear data presented in the table

yaroslaw [1]

Answer:

y = -7x

Explanation:

Take two points from table: (-4, 28), (-3, 21)

Find slope:

$\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} \ \ where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points$

$\rightarrow \sf slope\ (m): \dfrac{21-28}{-3-(-4)} = -7$

Now find equation:

$\sf y - y_1 = m (x - x_1)$

$\rightarrow \sf y - 21 = -7(x - (-3))$

$\rightarrow \sf y = -7(x +3) + 21$

$\rightarrow \sf y = -7x -21 + 21$

$\rightarrow \sf y = -7x$

Identify the domain and range of the function f(x) = 2x2 − 6x − 9.

mash [69]

Range is the y values or ouputs
domain is inputs or x vvalues

we can use any x value
but at a certain y value, w can't go below that
find thatminimum
find the vertex
for
ax^2+bx+c
the x value of the vertex is
-b/2a
plug that in to the equaiton to get the y value

-b/2a=-(-6)/(2*2)=6/4=3/2

plug that in
2(3/2)^2-6(3/2)-9
2(9/4)-9-9
9/2-18
4.5-18
-13.5

domain=all real numbers
range=from -13.5 to positive infinity

In 2005, the Summerville Journal had 110,000 subscriptions. The number of subscriptions subsequently decreased by 8% each year.

barxatty [35]

Answer:

The number of subscription will be 26,655 in 2022.

Step-by-step explanation:

In 2005, the number subscription is 110,000 and it is decreased at a rate 8% per year.

After 1 year number of subscription is 110,000- 8% of 110,00

=110,000(1-8%)

After 2 years number of subscription is 110,000(1-8%) -8% of 110,000(1-8%)

=110,000(1-8%)(1-8%)

=110,000(1-8%)²

After 2 years number of subscription is 110,000(1-8%)² -8% of 110,000(1-8%)²

=110,000(1-8%)²(1-8%)

=110,000(1-8%)³

....

and so on.

After t year the number of subscription is

$S(t)=110,000(1-8\%)^t$

t= 2022-2005=17 years

$\therefore S(t)=110,000(1+0.08)^{17}$

≈26,655

The number of subscription will be 26,655 in 2022.
