OQ = 8 + 9 = 17
x^2 = 17^2 - 8^2
x^2 = 289 - 64
x^2 = 225
x = 15

Answer:

x  = 15 cm.

Step-by-step explanation:

Given :Point O is the center of the circle.

To find : What is the value of x?

Solution : We have given that a circle of radius 8 cm .

The tangent to a circle is perpendicular to the radius at the point of tangency.

By applying the Pythagorean theorem

OQ² = OP² + PQ²

Plugging the values  OQ = 9 +8 , OP = 8 , PQ = x

(17)² = (8)² + (x)².

289 =  64 + (x)².

On subtracting 64 from both sides

289 -64 =  (x)²

225 = (x)²

On taking square root both side  

x = 15

Therefore, x = 15 cm.

What second degree polynomial function has a leading coefficient of -2 and root 4 with a multiplicity of 2
OverLord2011 [107]

The second degree polynomial with leading coefficient of -2 and root 4 with multiplicity of 2 is:

p(x) = -2*(x - 4)*(x - 4) = -2*(x - 4)^2

<h3>How to write the polynomial?</h3>

A polynomial of degree N, with the N roots {x₁, ..., xₙ} and a leading coefficient a is written as:

p(x) = a*(x - x_1)*(x - x_2)*...*(x - x_n)

Here we know that the degree is 2, the only root is 4 (with a multiplicity of 2, this is equivalent to say that we have two roots at x = 4) and a leading coefficient equal to -2.

Then this polynomial is equal to:

p(x) = -2*(x - 4)*(x - 4) = -2*(x - 4)^2

Choose all options that apply. In the US Customary System, which of the following terms is used to measure volume? a) Cup b) Tab
Naddik [55]

Answer:

D) Fluid ounce

Step-by-step explanation:

Fluid ounces are a <em><u>unit used to measure volume</u></em>, or <em>how much space something takes up.</em> This measurement is used for liquid ingredients, like water or milk. When a recipe calls for fluid ounces, go ahead and pull out your measuring cup; it's the most accurate way to measure this.

Answer:

a   10 yd   2ft  7 in

b 10 yd  1 ft  2 in

c  99 yd

d.  4840 sq  yd  7 sq ft  119 sq in  

Step-by-step explanation:

a.      2 ft. 5 in. +

9 yd. 3 ft. 2 in.

---------------------

9 yd   5ft   7 in

but 3 ft = 1yd

9 yd   5ft   7 in

+1yd   - 3ft

---------------------------

10 yd   2ft  7 in



b. 4 yd. 8 in

+ 6 yd. 6 in.

----------------------

10 yd   14 in

but 12 in = 1ft


10 yd       14 in

     + 1ft   - 12 in

---------------------

10 yd  1 ft  2 in



c. 29 yd. 2 ft. 11 in.

  55 yd. 1 ft. 10 in.

+ 13 yd. 1 ft. 3 in.  

--------------------------

97 yd   4 ft   24 in

12 in = 1ft

24 in = 2ft


97 yd   4 ft   24 in

           +2ft    - 24 in

--------------------------------

97 yd   6ft

3 ft = 1yd

6f = 2yd


97 yd   6ft

+2yd   - 6ft

---------------------

99 yd


d. 4,839 sq. yd. 8 sq. ft. 139 sq. in.

                      + 7 sq. ft. 124 sq. in.

--------------------------------------------------

  4839  sq yd  15 sq ft   263 sq in

12*12 = 144 sq in = 1 sq ft

 4839  sq yd  15 sq ft   263 sq in

                       + 1 sq ft  - 144 sq in

--------------------------------------------------

4839  sq yd  16 sq ft  119 sq in

3ft * 3 ft = 9 sq ft = 1 sq yd

4839  sq yd  16 sq ft  119 sq in

      +1 sq yd  - 9 sq ft

----------------------------------------------

4840 sq  yd  7 sq ft  119 sq in
