Answer: [tex]5027.2\ ft^2[/tex]
Step-by-step explanation:
Given
The radius of the circle is [tex]r=40\ ft[/tex]
The area of the circle is given by [tex]\pi r^2[/tex]
Insert the value of radius and get the area to play
[tex]\Rightarrow \text{Area A=}\pi \times 40^2\\\\\Rightarrow A=3.142\times 1600\Rightarrow A=5027.2\ ft^2[/tex]
Thus, the area to play is [tex]5027.2\ ft^2[/tex]

Here is the next one jaded :))
Answer:
x = 5.56
Step-by-step explanation:
Sin(17) = [tex]\frac{x}{19}[/tex]
=> Isolate the "x"
Sin(17) * 19 = x
5.56 = x

Find the Area of the figure below, composed of a rectangle with a semicircle
removed from it. Round to the nearest tenths place.
Answer:
Area of the figure = 25.7 units²
Step-by-step explanation:
Area of the given figure = Area of rectangle ABCD - Area of the semicircle with diameter CD
Area of the rectangle ABCD = Length × Width
= BC × AB
= 8 × 4
= 32 units²
Area of the semicircle = [tex]\frac{1}{2}\pi r^{2}[/tex]
Here, r = radius of the semicircle
r = [tex]\frac{\text{Diameter}}{2}[/tex]
r = [tex]\frac{1}{2}(CD)[/tex]
r = [tex]\frac{4}{2}[/tex]
r = 2 units
Therefore, area of the semicircle = [tex]\frac{1}{2}\pi (2)^2[/tex]
= 2π
= 6.28 units²
Area of the given figure = 32 - 6.28
= 25.72 units²
≈ 25.7 units²

At the end of each day of a bowling competition, half of the bowlers are eliminated until a winner is determined. There are 320 bowlers on day 1 of the competition. Which equation represents the number of bowlers, y, on the day x of the competition
Answer:
Step-by-step explanation:
Y= 320(1.5)^x-1
In this exercise we have to use the data informed in the text and perform the assembly of an equation in this way we find that:
[tex]Y=320(0.5)^X-1[/tex]
Some data were informed in the text for this equation to be written, so:
Y: the number of bowlersX: on the day320 bowlersNow writing the equation representing the given information is:
[tex]Y=320(0.5)^X-1[/tex]

Which is the solution for the system of equations? Y = 2x-3
Y = -x
A. (1, -1)
B. No solution
C. (-1, 1)
D. (-1, -1)
Answer:
(1,-1)
Step-by-step explanation:
[tex] \large{ \begin{cases} y = 2x - 3 \\ y = - x \end{cases}}[/tex]
Since both are y-isolated equation. We can combine both.
[tex] \large{2x - 3 = - x}[/tex]
Since we want to solve for x-term, we need to isolate x-term.
So we move from -x which is the right side to x.
[tex] \large{2x - 3 + x = 0} \\ \large{3x - 3 = 0} \\ \large{3x = 3} \\ \large{x = 1}[/tex]
But we are not done yet. Solving system of equations, you must solve for y-term as well. (Because we have to answer in ordered pairs which are (x, y))
Substitute x = 1 in any given equations but I will substitute x = 1 in y = -x
[tex] \large{y = - x} \\ \large{y = - 1}[/tex]
Since we have got y-value. Therefore the answer is (1,-1)

Expand and simplify (2x + 1)(x + 3)
expand and simplify (2x + 1)(x + 3)
answer : [tex]2x^2+7x+3[/tex]
-
explanation : expand the polynomial using the FOIL method.
-
FOIL : a technique for distributing two binomials. the letters FOIL stand for first, outer, inner, last. first means multiply the terms which occur first in each binomial, outer means multiply the outermost terms in the product, inner means multiply the innermost terms, and last means multiply the terms which occur last in each binomial.
-
step 1 : multiply each term in the first parentheses by each term in the second parentheses (FOIL)
ex : [tex]2x * x+2x * 3+x+3[/tex]
step 2 : calculate the product
ex: [tex]2x^2+2x * 3+x+3[/tex]
step 3 : calculate the product
ex: [tex]2x^2+6x+x+3[/tex]
step 4 : collect like terms
ex: [tex]2x^2+7x+3[/tex]
-
solution : [tex]2x^2+7x+3[/tex]

What would it cost to get x bananas and y bottles of soda?
Answer:
$7.5
Step-by-step explanation:
4 bottles cost = $5
Then 1 bottle costs:
$5/4 = $1.25

What is the sum of the first ten terms in a geometric series
with a1=
6 and r = 2?
Answer:
[tex]S_{10} = 682[/tex]
Step-by-step explanation:
Given
[tex]a_1 = 6; r = 2[/tex]
Required
[tex]S_{10[/tex]
This is calculated as:
[tex]S_n = \frac{a(r^n - 1)}{r - 1}[/tex]
So, we have:
[tex]S_{10} = \frac{6 * (2^{10} - 1)}{10 - 1}[/tex]
[tex]S_{10} = \frac{6 * (1024- 1)}{9}[/tex]
[tex]S_{10} = \frac{6 * 1023}{9}[/tex]
[tex]S_{10} = 682[/tex]

Find the argument of the complex number z=1+iv3
Given:
The complex number is:
[tex]z=1+i\sqrt{3}[/tex]
To find:
The argument of the given complex number.
Solution:
If a complex number is [tex]z=x+iy[/tex], then the argument of the complex number is:
[tex]\theta=\tan^{-1}\dfrac{y}{x}[/tex]
We have,
[tex]z=1+i\sqrt{3}[/tex]
Here, [tex]x=1[/tex] and [tex]y=\sqrt{3}[/tex]. So, the argument of the given complex number is:
[tex]\theta =\tan^{-1}\dfrac{\sqrt{3}}{1}[/tex]
[tex]\theta =\tan^{-1}\sqrt{3}[/tex]
[tex]\theta =\tan^{-1}\left(\tan \dfrac{\pi}{3}\right)[/tex]
[tex]\theta =\dfrac{\pi}{3}[/tex]
Therefore, the argument of the given complex number is [tex]\theta =\dfrac{\pi}{3}[/tex].

Complete the function table for each equation
Answer:
y=-32, 0, -16, -4, 16
Step-by-step explanation:
y=4(-6)-8= -32
y=4(2)-8 = 0
y=4(-2)-8 = -16
y=4(1) -8 = -4
y=4(6) -8= 16
For the given equation of the line, the complete table is attached below.
Use the concept of the equation of line defined as:
A line has length but no width, making it a one-dimensional figure. A line is made up of a collection of points that can be stretched indefinitely in opposing directions. Two points in a two-dimensional plane determine it.
The given equation of a line is,
y = 4x - x
To complete the table:
Put x = -6 in this equation,
y = (-4)(-6) - 8
y = 16
Put x = 2 in the equation,
y = (-4)(2) - 8
y = -16
Put x = -2 in the equation,
y = (-4)(-2) - 8
y = 0
Put x = 1 in the equation,
y = (-4)(1) - 8
y = -12
Put x = 6 in the equation,
y = (-4)(6) - 8
y = -32
The complete table is attached below.

5. What is the value of 8 in the unit circle below?
30°
600
b.
45°
d.
90°
9514 1404 393
Answer:
θ = 60°
Step-by-step explanation:
The angle is more than 45° and less than 90°. The only viable choice is ...
θ = 60°
__
We can only read the x-coordinate of the point on the terminal ray. It is 1/2, which is the cosine of 60°. The angle must be 60°.
A researcher wishes to test whether the mean of a normally distributed population is greater than 1.06 at the 5% significance level. Based upon 22 independent observations, she observes a sample mean of 1.77 and a sample standard deviation of 0.84. Determine the critical value of the test rounded to the nearest hundredth. (Rounding counts!).
Answer:
t- critical value =1.721
Step-by-step explanation:
Given
Sample size =n=22
Degree of freedom = sample size -1 = 22-1 =21
The significance level is 5%. This indicates that the test is right tailed.
The alpha value = 0.05
For given right tailed test, with value of alpha = 0.05 and degree of freedom = 21, the t- critical value =1.721
