Find the area of a regular pentagon with a radius of 9 yds. show all six steps.
Answer:
192.6 square yards
Step-by-step explanation:
The area of a regular pentagon can be found using the formula for any regular polygon.
A = (n/2)r²·sin(360°/n) . . . . radius r, n sides
For a pentagon, the number of sides is 5, so this becomes ...
A = 2.5r²·sin(72°)
__
Using the given value of radius, the area is ...
A = 2.5(9 yd)²·sin(72°) = 2.5 · 81 · 0.951057 yd²
A ≈ 202.5 · 0.951057 yd²
A ≈ 192.589 yd²
The area of the pentagon is about 192.6 square yards.

the diameter of fishing line varies. Fishing lines can have a diameter as small as 2 x 102 and as large
Answer:
We know that:
small diameter = 2 * 10^-2 in
large diameter = 6 * 10^-2 in
We want to know how many times larger is the thin diameter compared to the large one.
We will do this as follows:
large diameter = k * small diameter
where k is the number of times that we want to find
6 * 10^-2 = k * 2 * 10^-2
k = (6 * 10^-2) / (2 * 10^-2)
k = 3
This means that the large diameter is 3 times the small one.

coordinates of A after the translation.
1. Give the rule for translating a point 4 units left and 8 units up. (2 points)
Answer:
(3, 13)
Step-by-step explanation:
Original coordinates of A
A = (7, 5)After translating left 4 units
A' = (7 - 4, 5)A' = (3, 5)After translating up 8 units
A'' = (3, 5 + 8)A'' = (3, 13)

The scatter plot below shows the cost (y) of long distance phone call based on the number of minutes (x) the calls take. Part A. Draw a line of best fit on the scatter plot
Part B write the approximate equation of the line of best fit
It should be in slope intercept form.
Part C. Use your equation from part B to predict the cost of a long distance call that lasts 120 minutes. Be sure to show your work
Part D. Explain how you found your answer to Part C.
The scatter plot that shows the cost of long distance phone call is an illustration of a linear regression
Part A: Draw a line of best fitSee attachment for the line of best fit
Part B: The equation in slope intercept formFrom the attached graph, the line passes through the points:
(x,y) = (0,0) and (40,4)
The equation is then calculated using:
y = y2/y1 * x
This gives
y = 4/40 * x
Evaluate
y = 0.1x
Part C: Predict the cost of long distance call of 120 minutesThis means that x = 120
So, we have:
y = 0.1 * 120
y = 12
Hence, the predicted cost of long distance call of 120 minutes is $12
Part D: Explanation of CThe answer in part C is calculated by substituting 120 for x in the equation of the line of best fit

The diagram shown is two intersecting lines. The measure of 5 is 47°.
Please solve this on paper! I'll give brainliest to the best explanation. Thank you so much <3
Answer:
The measure of angle 7 is 47°
The value of x = 69
Step-by-step explanation:
(a) The measure of angle 7 is also 47° { therefore angle 5 angle 7 are vertically opposite angles so they are equal }
(b) if the angle 6 is represented by (2x-5) so the equation will be (2x-5) + angle 5 = 180° { linear pair}
(c)
=> 2x-5+47 = 180
=> 2x + 42 = 180
=> 2x = 180 -42
=> 2x = 138
=> x = 138/2
=> x = 69
Answer:
See below ↓↓↓
Step-by-step explanation:
(a) ∠7 = ∠5 (vertically opposite angles)
∠7 = 47°It is equal to 47 degrees, because the when a transversal cuts through a straight line, the angles which lay opposite to each other are equal(b) ∠5 and ∠6 form a line, so their sum is equal to 180°, which is the angle of a straight line. Therefore, our equation :
47 + 2x - 5 = 180(c) Solving for x :

The length of the hypotenuse is ___ ft.
Answer:
The length of the hypotenuse is 14 ft[tex] \: [/tex]
Step-by-step explanation:
We'll solve this using the Pythagorean theorem, we know that,
[tex]\\ {\longrightarrow \pmb{\sf {\qquad (Hypotenuse {)}^{2}= (Base) {}^{2} + (Perpendicular {)}^{2} }}}[/tex]
So, As it is given in the question that, the length of one leg of a right triangle is 9 ft and the length of the hypotenuse is 3 feet longer than the other leg and we are to find the length of the hypotenuse and the other leg.
[tex] \: [/tex]
Let us assume the other leg as x ft and therefore the hypotenuse will be (x + 3) ft.
[tex] \: [/tex]
Now, substituting the values in the formula :
[tex] \\ {\longrightarrow \pmb{\sf {\qquad (x + 3 {)}^{2} = (9 {)}^{2} + (x) {}^{2} }}} \\ \\ [/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad (x {)}^{2} + 2.x.3 + {(3)}^{2} =81 + (x) {}^{2} }}} \\ \\ [/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad \cancel{ (x {)}^{2}} + 2.x.3 +9 =81 + \cancel{(x) {}^{2} }}}} \\ \\ [/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad 6x + 9 =81 }}} \\ \\ [/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad 6x =81 - 9 }}} \\ \\ [/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad 6x =72 }}} \\ \\ [/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad x = \frac{72}{6} }}} \\ \\ [/tex]
[tex]{\longrightarrow \pmb{\frak {\qquad x =12 }}} \\ \\ [/tex]
Therefore,
The length of other leg is 12 ft . And the length of hypotenuse is (12 + 2) ft = 14 ft

Answer:
y = -2x² + 12x - 14
Step-by-step explanation:
Isolate the "-2" in (x - 3)² by using brackets:
⇒ y = -2(x - 3)² + 4⇒ y = -2[(x - 3)²] + 4Using the formula (a - b)² = a² - 2ab + b²:
⇒ y = -2[(x - 3)²] + 4⇒ y = -2[x² - 2(x)(3) + 3²] + 4Open the brackets on the R.H.S
⇒ y = -2[x² - 6(x) + 9] + 4⇒ y = -2x² + 12(x) - 18 + 4Simplify the expression on the R.H.S
⇒ y = -2x² + 12(x) - 18 + 4⇒ y = -2x² + 12x - 14James spent $98 at the mall. He purchased a pair of shoes for $55 and 2 t-shirts. Write an equation to show how much each t-shirt cost.

How do I solve?
Answer:

plus 48 on both sides
8p > 4p + 32
minus 4p on both sides
4p > 32
divide 4 on both sides, 32 ÷ 4 = 8, so,

Multiply 8(p-6) and 4(p-4)
You will get 8p - 48 > 4p - 16
Then add 48 to -16
Then you will get 8p > 4p + 32
Then subtract 4p from 8p
Then you will get 4p > 32
Then divide 4 from 4p and 32

What is the range of the function f(x) = 3x2 6x – 8?
The domain of the function 3x² + 6x – 8 is a real number and the range of the function 3x² + 6x – 8 will be (-11, ∞).
What are domain and range?The domain means all the possible values of the x and the range means all the possible values of the y.
The function is given below.
f(x) = 3x² + 6x – 8
The range of the function will be
f(x) = 3x² + 6x – 8
f(x) = 3x² + 6x + 3 – 11
f(x) = 3(x² + 2x + 1) – 11
f(x) = 3(x + 1)² – 11
Then the range of the function will be from -11 to infinity.

We're looking for the magnitude of the force - angles don't matter.
We need to resolve the two forces.
As you can see in the attached drawing, this basically just becomes Pythagoras.

Alice is making a necklace. She has a chain that is 400 mm long. She puts forty 1.7 mm beads, twenty-seven 6.5 mm beads, and eight 3.4 mm beads on the chain. How much of the 400 mm chain is left without bead?
Answer:
129.3mm chain left without beads
Step-by-step explanation:
Equation:
400mm long chain - [(40 x 1.7mm) + (27 x 6.5mm) + (8 x 3.4mm)]
= chain left without beads
Calculation:
40 beads x 1.7mm = 68mm
27 beads x 6.5mm = 175.5mm
8 beads x 3.4mm = 27.2mm
(68mm + 175.5 mm + 27.2mm) = 270.7mm chain with beads
400mm chain - 270.7mm chain with beads
= 129.3mm chain left without beads
