If the area of a circle is 144pi square meters, what is the area of the sector for 80 degrees of the circle, rounded to the nearest hundredth?

Answer:

A B D

Step-by-step explanation:

those are the answers

But a closer look shows that B will be the best answer.

Answer:

Since all the rhombus is parallelogram

some are trapezoid and quadrilateral.

So

B.parallelogram is a answer:

it opposite side are equal.

diagonal bisect angle equally.

x=10.4

Step-by-step explanation:

Answer:

1. 24p + 18

Step-by-step explanation:

One of the formulas used to find the perimeter of a rectangle is:

P = 2(l + w)

Where P is the perimeter, l is the length, and w is the width. We can substitute in the given values:

P = 2[(4p + 4) + (8p + 5)]

Now we can combine the like terms:

P = 2[12p + 9]

And simplify:

P = 24p + 18

This is the same as option 1.

Answer:

$550.80

Step-by-step explanation:

Value of concrete used = volume of the prism x cost per cubic foot

volume of the prism = base area x height

the base is in the shape of a triangle

Area of a triangle = (1/2) x base x height = 1/2 x 6 x 6 = 18

Volume of the prism = 18 x 10.2 = 183.6 ft^3

183.6 x 3 = $550.80

Step-by-step explanation:

Answer:

10.3699136~10

Step-by-step explanation:

First i found the area of the triangle, .5(10*7)=35

And the area of a circle formula is pi*r^2 so...

35-(pi*2.8^2)=35-24.6300864=10.3699136

Answer:

Only f(x) has an x-intercept.

All three functions have the same domain values.

Step-by-step explanation:

Given

See attachment for table

Required

Select two correct options

Checking the domain:

The x values represent the domain.

From the attached table, we have:

[tex]x = \{-4.-3,-2,-1,1\}[/tex]

These values of x apply to the three functions; f(x), g(x) and h(x).

This means that the functions have the same domain

Checking the greatest maximum

The maximum of each function is:

[tex]f(x) = 1[/tex]

[tex]g(x) = -4[/tex]

[tex]h(x) = 2[/tex]

Compare these three values, we have:

[tex]h(x) > f(x) > g(x)[/tex]

This means that h(x) has the greatest maximum

Checking the x intercept

When a function equals 0, then it has an x intercept

Of the three functions, we have:

[tex]f(-3) = 0[/tex] --- This represents the x intercept.

Other functions do not have this value.

This means that only f(x) has an x intercept

Answer:

Only f(x) has an x-intercept.

All three functions have the same domain values.

Answer:

16 units²

Step-by-step explanation:

Volume:

v = s³

64 = s³

Take the cube root of both sides

4 = s

Area:

a = s²

a = 4²

a = 16 units²

Answer:

subtracting 1 from 3

use BEDMAS for order of operation

brackets, exponents division, multiplication, addition, subtraction

all of em from left to right order

Here we have 2 brackets, so you choose the bracket inside bracket, cause that's how it is.

Answer:

The last graph is the answer

Step-by-step explanation:

I got this correct on the quiz

Answer:

Horizontal Asymptote: None (degree of numerator is larger than denominator)

Vertical Asymptote: None (domain of function is [tex]\mathbb{R}[/tex])

x-intercept: (0, 0)

y-intercept: (0, 0)

Hole: (-2, 1)

Step-by-step explanation:

HA: Since the degree of the numerator (2) is larger than the degree of the denominator (1), no HA exists.

VA: Since the domain of the function of is [tex]\mathbb{R}[/tex] (all real numbers), no VA exists. *no real value of x will make the denominator equal to 0 and numerator [tex]\neq[/tex] 0

x-intercept:

The x-intercept occurs at [tex]y=0[/tex].

Solving for x:

[tex]0=\frac{-2x^2-4x}{4x+8}[/tex]:

[tex]0=-2x^2-4x,\\x=0[/tex]. Therefore, the x-intercept is (0, 0).

y-intercept:

The y-intercept occurs when [tex]x=0[/tex].

Solving for y:

[tex]\frac{-2x^2-4x}{4x+8}, x=0,\\\frac{-2(0)^2-4(0)}{4(0)+8}=0[/tex]. Therefore, the y-intercept is (0, 0).

Hole:

When looking for a hole, we are looking for a factor that occurs in both the numerator and denominator:

[tex]\frac{-2x^2-4x}{4x+8}=\frac{-2x(x+2)}{4(x+2)}[/tex]

Rewriting our function here, we see that the term [tex](x+2)[/tex] occurs in both the numerator and denominator. Thus, when this term is set to 0, it will make both the numerator and denominator 0, thus rendering an undefined value (since we cannot divide by 0). We call this a hole. *Note: Usually when an x-value makes the denominator zero, this will create a vertical asymptote. However, if the x-value also makes the numerator zero, it's considered a hole, not an asymptote. The x-value of this hole will be the value of when the common term is equal to 0:

[tex]x+2=0,\\x=-2[/tex]

To find the y-value of the hole, remove the common term and plug in your x-value:

[tex]\frac{-2x^2-4x}{4x+8}=\frac{-2x(x+2)}{4(x+2)}=\frac{-2x}{4},\\\frac{-2(-2)}{4}=\frac{4}{4}=1[/tex]

Therefore, the hole of this function is at (-2, 1).

Answer:

(x + 4)^2 + 3 = 0

Step-by-step explanation:

When you multiply out (a + b)^2, you get a^2 + 2ab + b^2. We already know the a^2 term, which is x^2. We can deduct the first term of the square is x because x * x is x^2, and x would correspond with a. Next, we can connect the 2ab term with 8x, as it includes the variable x.

2ab = 8x

We have established a = x, so:

2xb = 8x

b = 4

We can put this together to get the square:

(x^2 + 8x + 16) + 3 = 0

(the three is added to get a last term of 19 in the given equation)

When we factor the square, it turns out as:

(x + 4)^2 + 3 = 0

Note: Sorry if the answer was a bit confusing, this is kinda hard to explain.
