Find the perimeter of the shaded region. Keep answer in exact form. rectangle with two semi circles within it. Semi circle have a diameter of 6 and regtangle has a lenght of 13

Answer:

y = x-4

Step-by-step explanation:

The standard form is;

y = mx + b

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

we have the two points as (0,-4) and (5,1)

so we find the slope using the slope formula;

m = (y2-y1)/(x2-x1)

m = (1 + 4)/(5-0) = 5/5 = 1

The y-intercept value is the value of y when x = 0

We already have a point (0,-4) and the equation would be:

y = 1(x) + (-4)

y = x-4

Answer:

x = 1/2,-3

Step-by-step explanation:

I think the answer is x = 1/2, -3.

One sec I'll answer this right now

-2 Is the answer!!

5 quarters is 125 cents 6 dimes is 60 cents 2 Nickels are 10 cents and 12 pennies are 12 cents all that in total is 207

Probability is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

The probability of drawing a dime and then a penny is 9/50.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

We have,

Number of coins = 6 dimes + 2 nickels + 12 pennies = 20

Number of dims = 6

Number of nickels = 2

Number of pennies = 12

The probability of drawing a dime.

= 6/20

= 3/10

The probability of drawing a penny.

= 12/20

= 6/10

= 3/5

Now,

The probability of drawing a dime and then a penny.

= 3/10 x 3/5

= 9/50

Thus,

The probability of drawing a dime and then a penny is 9/50.

Answer:

The median is 8.

How you get that is that you have to order these from smallest to biggest.

0,3,8,8,11,13,14

Next, you cut one from each side until you get one single number left. If you get two, then you add them together and divide it by 2.

46.4 inch

Step-by-step explanation:

Area=l×b

93.6 =5.2×b

93.6/5.2 =b

So b= 18

Again,

p=2(l+b)

p=2(18+5.2)

p= 2×23.2

p=46.4

Answer:

Obtuse triangle

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. There are different types of triangles such as right angled, acute, obtuse and isosceles triangle.

In right angle triangle, one angle is 90°. The square of the longest side (hypotenuse) is equal to the sum of the square of the two sides.

An acute triangle is a triangle with acute angles (less than 90°). The square of the longest side is less than the sum of the square of the two sides.

An obtuse triangle is a triangle with one obtuse angle (greater than 90°) and two acute angles (less than 90°). The square of the longest side is larger than the sum of the square of the two sides.

An isosceles triangle is a triangle with two equal sides.

Given a triangle whose side lengths are 8, 16, and 18, the longest side is 18.

Since no two sides are the same hence it is not an isosceles triangle.

Also, 18² > 16² + 8²; therefore this is an obtuse triangle

Step-by-step explanation:

21x.30=6.3

21-6.3= 14.7

If  shirt cost $21 last month and the price decreased by 30% then the new price is $14.7.

percentage, a relative value indicating hundredth parts of any quantity.

Given that a  shirt cost is $21 last month.

The  price decreased by 30% in this month.

We have to find the new price.

To find this we have to find 30 percentage of 21.

Convert 30 % to decimal value by dividing with 100 and then multiply the decimal value with $21.

30/100× 21

0.3×21

$6.3

So the amount decreased is $6.3

The new price we get by subtraction $6.3 from $21.

21-6.3

New price = $14.7

Hence, if  shirt cost $21 last month and the price decreased by 30% then the new price is $14.7.

Answer:

BC ≈ 20.9

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

BC² + AC² = AB²

BC² + 7² = 22²

BC² + 49 = 484 ( subtract 49 from both sides )

BC² = 435 ( take the square root of both sides )

BC = [tex]\sqrt{435}[/tex] ≈ 20.9 ( to the nearest tenth )

Answer:

(x + 1)(x + 2)(2x + 1)(x - 3).

Step-by-step explanation:

From the leading and last coefficients, 2 and -6  the values +/- 1, +/-2 , +/- 3 could be roots of this equation ( well, up to 4 of them).

Try x = 1:

f(1) = 2(1)^4 + 1^3 - 14(1)^2 - 19(1) - 6 = -36 so its not 1.

f(-1) = 2 - 1 - 14 + 19 - 6 = 0 do x = -1 is a root.

Therefore (x + 1) is a factor  (By the factor theorem)

Try x = 2:

f(2) =  32 + 8 -56 - 38 - 6 = -6o so x =2 not a root.

f(-2) = 32 - 8 - 56 + 38 - 6 = 0 so x = -2 is a root and (x + 2) is a factor.

(x + 1)(x + 2) = x^2 + 3x + 2.

Long division:

                        2x^2 - 5x - 3   <-----------Quotient

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

x^2 + 3x + 2 )     2x^4  +   x^3   -14x^2 -  19x  -  6

                          2x^4  + 6x^3 +  4x^2  

                                      -5x^3  - 18x^2 - 19x

                                      -5x^3  - 15x^2 - 10x

                                                      -3x^2 - 9x  - 6

                                                      -3x^2  - 9x - 6

                                                       .......................

2x^2 - 5x - 3 = (2x + 1)(x - 3)

So Finally,   the factors are (x + 1)(x + 2)(2x + 1)(x - 3).

Answer:

x = 10/7 or x = -10/7

Step-by-step explanation:

By using the completing the squares method, we have to divide the coefficient of the x term by 2, square it and add to both sides

From what we have here, the coefficient of the x term is 0

Thus, we have it that;

0 = 100 - 49x^2

We can proceed to use the difference of two squares here;

Whereby;

a^2 - b^2 = (a-b)(a + b)

0 = (10-7x)(10+7x)

10 - 7x = 0 or 10 + 7x = 0

7x = 10 or 7x = -10

x = 10/7 or x = -10/7
