A diameter of a circle has enpoints (-2, 10) and (6, -4) in the standard (x, y) coordinate plane. What is the center of the circle?
Answer:
The center of the circle is [tex]C(x,y) = (2, 3)[/tex].
Step-by-step explanation:
The center of the circle is the midpoint of the segment between the endpoints. We can determine the location of the center by this vectorial expression:
[tex]C(x,y) = \frac{1}{2}\cdot R_{1}(x,y)+ \frac{1}{2}\cdot R_{2}(x,y)[/tex] (1)
Where:
[tex]C(x,y)[/tex] - Center.
[tex]R_{1} (x,y)[/tex], [tex]R_{2} (x,y)[/tex] - Location of the endpoints.
If we know that [tex]R_{1} (x,y) = (-2,10)[/tex] and [tex]R_{2} (x,y) = (6,-4)[/tex], then the location of the center of the circle is:
[tex]C(x,y) = \frac{1}{2}\cdot (-2,10)+\frac{1}{2}\cdot (6,-4)[/tex]
[tex]C(x,y) = (-1, 5) + (3, -2)[/tex]
[tex]C(x,y) = (2, 3)[/tex]
The center of the circle is [tex]C(x,y) = (2, 3)[/tex].

10. Solve for all values of x algebraically (find the zeroes):
3x^2 +12x – 7 = x^2+ 3x – 2
Answer:
x = -5 or 1/2
Step-by-step explanation:
From the question,
3x²+12x-7 = x²+3x-2
Collect like terms
3x²-x²+12x-3x-7+2 = 0
2x²+9x-5 = 0
Using factorization method to solve the quadratic equation
2x²+10x-x-5 = 0
(2x²+10x)-(x+5) = 0
2x(x+5)-1(x+5) = 0
(x+5)(2x-1) = 0
Either,
x+5 = 0
x = -5
or,
2x-1 = 0
2x = 1
x = 1/2.
Therefore,
x = -5 or 1/2
Nike and Adidas are having a huge sale for the next 5 days. Create a graph to determine if the shirts and cost are proportional.
A) Is the number oft-shirts proportional to the cost?
B) Write an equation to illustrate the relationship between the number of t-shirts and cost?
C) Using the equations predict the cost of 20 shirts sold.
D) 1%at docs the point (5, 35) represent in the context ofthc situation pertaining to Nike?
E) Which company has the better cost per shirt?
Answer:
See the graph with both lines attached
A) From the tables we see the constant change of values in the second column and the initial value is zero.
This represents a proportional relationship.B) Rate of change is 7 per shirt, the equation is:
y = 7x, where y is cost, x - is the number of shirtsC) When x = 20,
y = 7*20 = 140Cost of 20 shirts is $140D) The point (5, 35) represents that:
The cost of 5 shirts is $35E) The second table has confusing titles (not about the number or cost of shirts) but if we assume its same as the first table, then Adidas has greater price of $8 per shirt.
Comparing the prices, Nike has better cost
price of $8 per shirt.
Comparing the prices, Nike has better cost

A car requires 45 liters of petrol to travel a distance of 330 km.
1) the distance that the car can travel on 85 liters of petrol
2) the amount of petrol that the car owner has to pay to travel a distance of 990km if a liter of petrol costs $ 2.25.
Answer:
1) The car travels 623.333 kilometers with 85 liters of petrol.
2) The owner of the car must buy 135 liters of petrol at a total cost of $ 303.75 to travel 990 kilometers.
Step-by-step explanation:
1) The distance traveled by the car is directly proportional to the quantity of petrol. Then, we determine the distance needed by this simple rule of three:
[tex]x = \frac{85\,L}{45\,L}\times 330\,km[/tex]
[tex]x = 623.333\,km[/tex]
The car travels 623.333 kilometers with 85 liters of petrol.
2) The quantity of petrol is directly proportional to the traveled distance, which is directly proportional to cost. First, we calculate the quantity of petrol spent by the car:
[tex]x = \frac{990\,km}{330\,km}\times 45\,L[/tex]
[tex]x = 135\,L[/tex]
And the cost of 135 liters of petrol is:
[tex]y = 135\,L\times 2.25\,\frac{\$}{L}[/tex]
[tex]y = \$\,303.75[/tex]
The owner of the car must buy 135 liters of petrol at a total cost of $ 303.75 to travel 990 kilometers.
What is the surface area of the box if it is scaled up by a factor of 10?
the surface area is 206 in, width 9 in, length 13 in, height 4 in
(first to answer gets brainly please need answer quick!)
Answer:
6l², where l is the length of one side.
If the side is increased 10 times,
6(10l)²
=100 x6l²
The surface area increases 100 times. Thus, the new surface area is
272 * 100
= 27,200 sq in

Ramon earns $1670 each month and pays $53.00 on electricity. To the nearest tenth of a percent, what percent of Ramon's earnings are spent on electricity each month?
Answer:
the percentage of the ramon earnings spent on electricity is 3.17%
Step-by-step explanation:
The computation of the percentage of the ramon earnings spent on electricity is shown below:
= Pays for electricity ÷ earnings per month
= $53 ÷ $1,670
= 3.17%
Hence, the percentage of the ramon earnings spent on electricity is 3.17%

The scatter graph for level of water in a dam on each day and date for one month type of data is most likely to suggest a linear association.
What is scatter plot?A scatter plot, like a scatter chart or graph, employs dots to represent the values of two numerical variables. The horizontal value represents the data from individual points. Hence, it is used to observe the relationships between variables.
The scatter plot can provide the values for the data set. The points can be of various sizes, colours, and forms. The information is presented in the form of points.
The values are represented on the vertical axis. The data association can be positive, negative, or neutral. A mosaic and a fluctuational diagram can be displayed on the scatter plot.
Thus, the plot which can be linear association form level of water in a dam on each day and date for one month

Nella travelled 1/3 of a journey by bus, 2/3 of the remainder by bicycle and the remaining 9 km on foot. a)How far did Nella cycle? b)What was the total distance that Nella travelled?
Answer:
18km
40.5km
Step-by-step explanation:
Let b = journey by bus
c = journey by bicycle
d = total journey
c = (2/3 x d) x 2/3
divide both sides by 2/s
c(3/2) = (2/3)d
c + 9km = 2/3d
c + 9km = 3/2 c
collect like terms and solve for c
3/2c - c = 9km
1/2c = 9km
c = 18km
2. IF cycling (18km) and walking (9km) make up 2/3 of the journey, 2/3 of the journey is 27km
2/3d = 27km
divide both sides by 3/2 to find d
d = 40.50 km

Answer:
x ≤ 2
(when graphed, closed circle on two, shaded to the left)
Step-by-step explanation:
3/4 x - 2/3 ≤ 5/6
Add 2/3 to both sides:
3/4x ≤ 5/6 + 2/3
3/4x ≤ 3/2
Divide by 3/4 on both sides:
x ≤ 3/2 ÷ 3/4
