write an equation parallel to the function y=-4x+1 and goes through the point (1,1)
Y=???
Answer:
-4x + 5
Step-by-step explanation:
to be parallel, you need the same slope,
so it has to be -4x
and to go through the point (1,1) the y intercept has to be 5
because if you are using that slope, going down four and over one starting at (0,5) will connect the line to (1,1)
If it helps to draw it out or somehow visually see it, that would be a great idea
but in sum, the only answer is y = -4x + 5
(i didn't see someone had already answered)
(but the answer above uses the slope of 2x and I am unsure why because it says -4x on your question)
(so I guess you could just look at both and see what you need :))

find each angle measure in the regular polygon
a. 144°
b. 135°
c. 180°
d. 140°
=====================================================
Work Shown:
E = exterior angle
n = number of sides
For any regular polygon, E = 360/n.
In this case, n = 10 as there are 10 sides, so E = 360/n = 360/10 = 36 degrees is the measure of each exterior angle.
Each interior angle is 180-E = 180-36 = 144 degrees
--------------
An alternative is to plug n = 10 into the formula below to get the measure of each interior angle i
i = 180(n-2)/n
i = 180(10-2)/10
i = 180(8)/10
i = 1440/10
i = 144
note: S = 180(n-2) is the sum of all the interior angles of any convex polygon. Dividing this sum over n will evenly divide the angle total to each interior angle.

Step-by-step explanation:
Step 5 is to ( C ) take the Square root of both sides
The radius of the cone is ( A ) 2 inches
The radius of the cone is 2 inches.
The volume of cone:The volume of a cone is determined by the amount of space occupied by the cone. A three-dimensional figure having a single circular base is known as a cone. The base and the vertex are connected by a curved surface. A cone with a radius of r has a volume V that is one-third the area of the base B times the height h.
[tex]V=\frac{1}{3} \pi r^{2} h[/tex] or [tex]V=\frac{1}{3} Bh[/tex],
Since, [tex]B=\pi r^{2}[/tex]
How to determine the volume of cone?Given that the volume of cone V is 48π cubic inches and Height of the cone h=36 inches.Volume of cone [tex]V=\frac{1}{3} \pi r^{2} h[/tex] -------1
Here, the base of the cone is circular in shape and the area of circle is [tex]\pi r^{2}[/tex]. Consider [tex]B=\pi r^{2}[/tex]
Substituting the area of base in the equation (1).
[tex]V=\frac{1}{3} \pi r^{2}[/tex]
[tex]= \frac{1}{3} Bh[/tex]
Substitute the given values in the equation (1).
⇒ [tex]48\pi =\frac{1}{3} \pi r^{2} 36[/tex]
⇒ [tex]\frac{48\pi }{36\pi } =\frac{r^{2} }{3}[/tex]
⇒ [tex]\frac{12(3)}{9}=r^{2}[/tex]
⇒[tex]4=r^{2}[/tex]

Your family plays a money game where the first person chosen wins $1, the second person chosen wins $5, the third person chosen wins $10, and the fourth person chosen wins $50. Since you won the $50 prize during the last game, you are in charge of the choosing this time (so you cannot win). How many different winning scenarios are possible in this play of the money game?
Final answer:
There are 24 different winning scenarios possible in the family money game, calculated using permutations since the person in charge of choosing cannot win and there are three distinct prizes to be distributed among four participants.
Explanation:
The family money game presents a probability problem where one must calculate the number of different winning scenarios. Since there are five people including you, and you cannot win because you are the one choosing, you only need to consider the remaining four participants. Each person can win one of the three prizes - $1, $5 or $10 - since you won the $50 prize last time and you are exempt from winning again.
We need to look at the number of ways to arrange three distinct prizes among four people. This can be calculated using permutations where the order of assignment is important.
The formula for permutations is given as P(n, k) = n! / (n-k)!, where n is the total number, and k is the number to choose. In this case, n=4 (people) and k=3 (prizes). Hence, the calculation for permutations would be P(4, 3) = 4! / (4-3)! = (4 x 3 x 2 x 1) / 1 = 24.
Therefore, there are 24 different winning scenarios possible in this play of the money game.

Which is a factor of x2 - 9x + 14?
X-9
x-2
x + 5
X +7
ANSWER
x-2
b
Answer:
(x - 2)
Step-by-step explanation:
Given
x² - 9x + 14
Consider the factors of the constant term (+ 14) which sum to give the coefficient of the x- term (- 9)
The factors are - 2 and - 7, since
- 2 × - 7 = + 14 and - 2 - 7 = - 9, thus
x² - 9x + 14 = (x - 2)(x - 7) ← in factored form
Thus (x - 2) is a factor of the expression
The walls and ceiling of a hotel room are to be painted. The floor is a 14-foot square and the ceiling is 8 feet high. Ignoring any doors or windows, what is the surface area of the walls and the ceiling to be painted
The total surface area to be painted in the hotel room is 644 square feet.
To calculate the surface area of the walls and the ceiling to be painted in a room, we separate the two calculations since the walls and the ceiling have separate dimensions. The floor of the room is a 14-foot square, which means that each side of the wall is 14 feet long. The ceiling also has the same dimensions as the floor. The room has a height of 8 feet.
The area of the ceiling is equal to the area of the floor since they are both squares with the same side length, which is calculated as follows:
Area of ceiling = Side length × Side length
Area of ceiling = 14 feet × 14 feet = 196 square feet
Next, we calculate the surface area of the walls. There are four walls in the room, and each wall has the same height of 8 feet. The wall area is calculated as follows:
Area of one wall = Side length × Height
Area of one wall = 14 feet × 8 feet = 112 square feet
Since there are four walls, total wall area = 4 × 112 square feet = 448 square feet
Finally, we add the area of the ceiling to the total wall area to get the total surface area to be painted:
Total surface area = Ceiling area + Wall area
Total surface area = 196 square feet + 448 square feet = 644 square feet
Therefore, the total surface area of the walls and ceiling of the room that will be painted is 644 square feet, ignoring any doors or windows.

complete question:
The green area in the figure above represents a section of grass for a putting green. Find the area of the sector of grass.
A. A= 32π ft²
B. A= 6π ft²
C. A= 36π ft²
D. A= 72π ft²
Answer:
C. A= 36π ft²
Step-by-step explanation:
The image below is where your question emanated. The area of the sector of grass can be calculated below.
Area of a sector = ∅/360 × πr²
where
∅ = angle from the center of the circle
r = radius
Area of a sector = ∅/360 × πr²
r = 12 ft
∅ = 90°
Area of a sector = 90/360 × π × 12²
Area of a sector = 90/360 × π × 144
Area of a sector = 1/4 × 144π
Area of a sector = 144π/4
Area of a sector = 36π ft²

Dan bought a new computer for $900. Each year, the value of
the computer decreased by 25% of the previous year's value. At
this rate, what can Dan expect the approximate value of the
computer to be after 8 years?
A
$84
B
$90
C
$100
D
$113
Answer:
B) $90
Step-by-step explanation:
To work out the value of the computer after 8 years you would first have to convert the percentage into a decimal. To achieve this you would divide the percentage of 25 by 100, which gives you 0.25. This is because percentages are out of 100. The next step is to minus 0.25 from 1, which gives you 0.75. This is because the value of the computer is diminishing. Then you would multiply 900 by 0.75 to the power of 8, which gives you 90. You would multiply to the power of 8 as the percentage decrease will need to take place 8 times due to it being annual.
1) Divide 25 by 100.
[tex]25/100=0.25[/tex]
2) Minus 0.25 from 1.
[tex]1-0.25=0.75[/tex]
3) Multiply 900 by 0.75 by the power of 8.
[tex]900*0.75^{8} =90.1[/tex]
4) Round to the nearest whole number.
90
Final answer:
Using the exponential decay formula, the value of Dan's computer after 8 years, with a 25% annual decline, is approximately $90, corresponding to option B.
Explanation:
The question asks about the depreciation of the value of a computer over time. To calculate the approximate value of Dan's computer after 8 years, with a 25% annual decrease in value, we can use the formula for exponential decay - V = P(1 - r)^t, where V is the final value, P is the initial value, r is the rate of decay, and t is the time in years.
The annual rate of decay, r, is 25% or 0.25.
The time in years, t, is 8 years.
Substituting these values into the formula gives us:
V = 900 (1 - 0.25)^8 = 900 (0.75)^8 = 900 * 0.10011291504 ≈ $90.10
After rounding, Dan can expect the approximate value of the computer to be about $90 after 8 years, which corresponds to option B.
