What is the arc measure of minor arc AB in degrees?

Answers

Answer:

The measure of a minor arc is the measure of its central angle. The expression m AB is read as “the measure of arc AB.” The measure of the entire circle is 360°. The measure of a major arc is the difference of 360° and the measure of the related minor arc.

The library made a table to track the number of fiction and nonfiction books checked out for 6 days.
On the first day, 18 fiction books are checked out, and 12 nonfiction books are checked out.
Each day after 18 fiction books are checked out, and 12 nonfiction books are checked out.
Drag the numbers from the box to complete the table.
Numbers may be used once, more than once, or not at all.

Which function is the inverse of function f?
f(x)=9x^2–12

Answers

Answer: D

Step-by-step explanation:

If the equation is f(x) = 9x^2 -12, you can solve for the inverse by switching the x and y like this.

x = 9y^2-12.

Then you solve for y.

x = 9y^2-12.

x+12=9y^2

y^2=(x+12)/9

y=sqrt((x+12)/9)

y=sqrt((x+12))/3 which is D

What is the equation of the line that passes through (0, 3) and (7,0)?
y-ix-3
3
y=x+3
3
y y=-7x+3
y=-x-3

Answers

Answer:

The equation of the line in slope-intercept form is:

[tex]y=-\frac{3}{7} x+3\\[/tex]

In one of the many possible standard forms:

[tex]3\,x+7\,y=21[/tex]

Step-by-step explanation:

First calculate the slope of the segment that joins these two points: (0, 3) and (7,0):

[tex]slope=\frac{y_2-y_1}{x_2-x_1}= \frac{0-3}{7-0}=-\frac{3}{7}[/tex]

Now, knowing that the y-intercept is (0, 3) [point on the y-axis (for x=0) where the line crosses], Then the equation of the line in slope-intercept form is:

[tex]y=m\,x+b\\y=-\frac{3}{7} x+3[/tex]

And now, if you want to write the equation eliminating fractions, we can multiply both sides by "7":

[tex]y=-\frac{3}{7} x+3\\7\,y=-3\,x+21\\3\,x+7\,y=21[/tex]

Answer:

Quadratic Equations! Yes!

Step-by-step explanation:

Now, there are three methods to solving this:

1.Quadratic Formula

2.Factoring

3. Completing the square

Now, Based on the answers, I think it would be better if we used Quadratic Formula, as you cannot get the answer easily with factoring, and I'm a bit rusty on completing the square.

So, Quadratic Formula! To solve it using this method, we have to find x using this: [tex]x=\frac{-b+-\sqrt{b^{2} -4ac} }{2a}[/tex](the +- before the square root means it could be both positive or negative)

Where a, b are coefficients and c is a term(in a quadratic equation form: [tex]ax^{2} +bx+c=0[/tex])

So, we just have to input the stuff from our equation into the formula!

[tex]x=\frac{-4+-\sqrt{32} }{2}[/tex]

Now, we can simplify the square root of 32 into 4 times the square root of 2

[tex]x=\frac{-4+-4\sqrt{2} }{2}[/tex]

And, we can divide 2 from it all!

[tex]x=-2+-2\sqrt{2}[/tex]

So, there you have it! The Answer is C, or 3.

Hope this helps!

Find the diagonale of the base.

Answers

Answer: 8.94

Step-by-step explanation:

By common logic, you can say that l=8, w=4 and h=2.

The diagonal of the base can be found by using Pythagorean Theorem.

Pythagorean Theorem: a²+b²=c²

Since we know the a and b of the base, we can find c, the diagonal.

a and b is the l and w. We can use the equation to find c.

8²+4²=c²

64+16=c²

80=c²

c=√80

c≈8.94

The diagonal is approximately 8.94

Answer:

Step-by-step explanation:

A) Cost of canvas = $ x

Cost of  4 canvases = 4 *x = 4x

Money left over after buying 4 canvases = $2.20

Equation:  25 - 4x = 2.2

Solution:     Subtract 25 from both sides

                -4x = 2.2 - 25

               -4x = - 22.8

Divide both sides by (-4)

    -4x/-4 = -22.8/-4

              x =  5.7

B) Money in Molly's account= x

4 times of Molly's account  = 4x

Equation: 4x - 2.2 = 25

Solution:   4x = 25 +2.2

                  4x = 27.2

                    x = 27.2/4

                   x = 6.8

Can someone help me find the slope , y-intercept ,and equation pls help it’s my finals

Answers

Answer:

slope: -3

y-intercept: -5

equation: y = -3x - 5

Step-by-step explanation:

The formula for slope is:

(y2 - y1)/(x2 - x1)

Let's use these coordinates:

(-1, -2)

(0, -5)

x1 = -1

x2 = 0

y1 = -2

y2 = -5

Substitute into the formula:

(y2 - y1)/(x2 - x1)

(-5 + 2)/(0 + 1)

Solve:

(-5 + 2)/(0 + 1)

-3/1

= -3

slope = -3

The y-intercept is when the x coordinate is 0.

Looking at the table, we see the coordinate (0, -5).

The y-coordinate is -5.

This means that the y-intercept is -5

y-intercept = -5

Slope-intercept form:

y = mx + b

where m is the slope and b is the y-intercept

m = -3

b = -5

Substitute:

y = mx + b

y = -3x - 5
