Find the standard form of the equation of the circle with endpoints of a diameter at the points (3,4) and (-9,6).
Answers
Answer:
(x + 3)² + (y - 5)² = 37Step-by-step explanation:
The center is the midpoint of the diameter, the coordinates are:
x(M) = (3 - 9)/2 = -3y(M) = (4 + 6)/2 = 5The length of the diameter:
[tex]d = \sqrt{(-9-3)^2+(6-4)^2} = \sqrt{12^2+2^2} = \sqrt{148} = 2\sqrt{37}[/tex]The radius is:
r = d/2 = [tex]2\sqrt{37} /2 = \sqrt{37}[/tex]The standard form is:
(x - h)² + (y - k)² = r², where (h, k) is the centerSubstitute to get:
(x - (-3))² + (y - 5)² = (√37)²(x + 3)² + (y - 5)² = 37A regular hexagon is a six sided figure with all sides equal and all six angles equal. Find the length of the sides if the perimeter of the regular hexagon is 396 yd.

Write the equation of the line that is parallel to x – 3y = 9 and passes
through the point (3, -1).
Answers
Step-by-step explanation:
the equation of the line that is parallel to
x – 3y = 9
=> the slope = -1/-3 = ⅓
passes through the point (3, -1) =>
y -(-1) = ⅓(x -3)
y+1= ⅓x - 1
y = ⅓x -1-1
y = ⅓x - 2
or

A graph titled Caffeinated Drinks has drink on the x-axis and relative frequency on the y-axis. Coffee, 0.8; tea, 0.75; Soda, 0.75; energy, 0.2. The coffee, tea, and soda pictures are large, and the energy drink picture is small.
Is this graph misleading?
No, because the pictures accurately represent the percentage of each type of drink.
No, because the height of each picture corresponds to the percentage of each type of drink.
Yes, because the height of each picture does not correspond to the percentage of each type of drink.
Yes, because the areas of the pictures do not accurately represent the proportions of each type of drink.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The correct option is B.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
From the given equation that is true are,
A. 63 x 103 = 63,000
If we multiply 63 and 103 the product will be 6,489. Since the two sides of the equation are not true, therefore, the given equation is false.
B. 63 x 10,000 = 630,000
If we multiply 63 and 10,000 the product will be 630,000. Since the two sides of the equation are true, therefore, the given equation is true.
C. 63 x 102 = 630
If we multiply 63 and 102 the product will be 6,426. Since the two sides of the equation are not true, therefore, the given equation is false.
D. 63 x 1,000 = 6,300
If we multiply 63 and 1,000 the product will be 63,000. Since the two sides of the equation are not true, therefore, the given equation is false.
E. 63 x 105 = 6,300,000
If we multiply 63 and 105 the product will be 6,615. Since the two sides of the equation are not true, therefore, the given equation is false.
Hence, the correct option is B.

Answer:
AM=1 false
BM= ½ true
AM=½ false
BM= √3/2 false
AM= ✓3/2 true
BM=1 false
Step-by-step explanation:
Since the triangle is equilateral it means that all sides are of the same length. So AB=1, BC=1, AC=1
AM=1 false because the formula to calculate the height of the equilateral triangle having the side is H=√3/2L = AM=√3/2
BM= ½ true because BC=1 so BM (half)=0,5=½
AM=1 false because the formula to calculate the height of the equilateral triangle having the side is H=√3/2L = AM=√3/2
BM= √3/2 false because it's ½
AM= ✓3/2 true because the formula to calculate the height of the equilateral triangle having the side is H=√3/2L = AM=√3/2
BM=1 false because BM= ½
