Answer 1

Answer:

Answer:

Step-by-step explanation:

Given 2 secants from a point outside the circle.

Then the product of the external part and the entire secant of one secant is equal to the product of the external part and the entire secant of the other secant, that is

(x + 1)(x + 1 + 11) = (x + 4)(x + 4 + 1)

(x + 1)(x + 12) = (x + 4)(x + 5) ← expand both sides

x² + 13x + 12 = x² + 9x + 20 ← subtract x² + 9x from both sides

4x + 12 = 20 ( subtract 12 from both sides )

4x = 8 ( divide both sides by 4 )

x = 2 → A

How can u figure out this problem?

Answers

First do the one in parenthesis, find out the exponent, and get a calculator or use your head to solve the rest of the problem.

according to bidmas we do the brackets first 7-5=2
then we use the index to make it 8
now we do multiplication so 4x8=32
and lastly 69-32=37

Explain how you can tell that 31/33 is in the simplest form

Answers

In order to simplify a fraction, you need to divide the top and bottom
by the same number. That means that the top and bottom must have
a common factor ... you have to find that first, before you can start
simplifying. Maybe that's why they teach common factors before they
teach simplifying fractions.

Anyway, I can take one look at this fraction and see that the top and
bottom have no common factor. In fact, the top number ... 31 ... is a
prime number, so it doesn't have any factors at all, except ' 1 ' and itself.

And that's how I can tell that the fraction is in the simplest form.

Simplest form is a form in which we cann't divide the fractions digits like 31/33

there are 23 boxes of pencil in mr. Shaw's Supply Cabinet Each Box contains 100 pencils how many pencils are in the supply cabinet

Answers

I believe there are 2300 pencils because 23 x 100 = 2300

Hoped this helped!

2300 because since there are 23 boxes and 100 pencils in each box, you'd do 23*100 to get 2300pencils in the supply cabinet

Answer:

C. The graph would shift five units to the left.

Step-by-step explanation:

y = x² + 5x - 2

We can write this equation in the form

y = a(x - h)² + k

If you change the value of h, you are translating the parabola horizontally.

If you increase h by five units, the graph shifts five units to the left.

In the figure below, the red parabola represents the original equation.

The blue parabola shows the graph shifting five units to the left

(from x = -2.5 to x = -7.5) when you replace x by x + 5.

Answer:

C. The graph would shift 5 units to the left

Step-by-step explanation:

If (x+5) was substituted in the place of x then it would shift 5 units to the left

Answer is C.

A 30-30-120 isosceles triangle has two legs of length 4 units. If it is rotated around an axis that contains one leg, what is the volume of the solid of revolution?

Answers

Volume of the solid of revolution is 127.47 cubic units

What is Isosceles triangle?

An isosceles triangle is a triangle that has two sides of equal length.

What is Volume?

Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface.

What is Solid of revolution?

A solid of revolution is a solid figure obtained by rotating a plane curve around some straight line that lies on the same plane

Angles of the given isosceles triangle = 30-30-120 triangle

Length of the leg = 4 units

Length of the Third side c = $\sqrt{a^(2)+b^(2)-2ab cos C }$

Where a and b are the length of the leg and C is the vertex angle

Then,

Length of the third side c= $\sqrt{4^(2)+4^(2)-2(4)(4)cos120 } =4√(3)$

It is rotated around an axis that contains one leg

Draw the figure,

From the figure we can say that we have to subtract the volume of the big cone from the volume of the small cone to find the required volume of the cone

Volume of big cone = $(1)/(3)\pi r^(2)\sqrt{l^(2).r^(2) }$
