two fixed points X and Y is
A. the perpendicular bisector of the line segment X Y
B. a line parallel to the line segment XY C. a circle with XY as diameter
D. the line perpendicular to the lin
Answer:
A. the perpendicular bisector of the line segment XY
Step-by-step explanation:
You know that one point equidistant from X and Y is the midpoint of segment XY. The third vertex of an isosceles triangle with XY as its base will also be equidistant from X and Y. That vertex will be located on the perpendicular bisector of XY.
The locus of points of interest is the perpendicular bisector of XY.

What are the coordinates of the point on the directed line segment from (3, 3) to (7,−5) that partitions the segment into a ratio of 5 to 3
Answer:
The coordinates of the point is (5.5, -2)
Step-by-step explanation:
Okay, what we want to do here is to get the point that divides the line that joins the points (3,3) to (7,-5) in the ratio 5 to 3
Generally, given the ratio a:b and we want to divide the line joining the points (x1,y1) and (x2,y2) in that ratio, we use the condensed formula below;
Let’s call the point dividing the line in the given ratio z.
The coordinates of Z is;
{(bx1 + ax2)/(a+b), (by1 + ay2)/(a+b)}
In this question (x1,y1) = (3,3)
While (x2,y2) = (7,-5)
while a:b = 5:3
Substituting these values into the coordinate equation for point z, we have ;
{((3(3) + 5(7))/(5+3), ((3)(3) + 5(-5))/(5+3)}
= {44/8 , -16/8} = {5.5, -2}
Rubi tosses a quarter off the Main Street bridge into the St. John’s River. The distance, in feet, the quarter is above the water is modeled by the equation d(t) = −16t2+96t + 112, where t represents time in seconds.
Answer: a. 112 feet, b= 3 seconds, c= 256 feet, d = 6 seconds
Step-by-step explanation:
Here is the complete question:
Rubi tosses a quarter off the Main Street bridge into the St. John’s River. The distance, in feet, the quarter is above the water is modeled by the equation d(t) = −16t2+96t + 112, where t represents time in seconds.
Find the actual value(s) now to each question. Use the solution from the previous question to assist you with what you are actual solving for.
(a) From what height was the quarter tossed?
The quarter was tossed at 112 feet.
(b) How long does it take the quarter to reach its maximum height?
It will take ________ seconds for the quarter to reach its maximum height.
(c) What is the maximum height of the quarter?
The maximum height of the quarter is ________ feet.
(d) How much time does it take for the quarter to hit the water?
It will take ______ seconds for the quarter to hit the water.
a. Since the function is
d(t) = −16t² + 96t + 112,
The coin is tossed at 112 feet. This is because it is the the initial value of the function. It is the constant term and does not depend on any other variable.
b. To calculate the maximum height, we have to find vertex of the function, that has coordinates of h,k and,
h = -b/2a and k = f(h).
From the question, we are aware that,
a = -16, b = 96, c = 112
Using the values, the vertex will be:
h = -b/2a
= -96/(2 × -16)
= -96/-32
= 3
k = f(3)
= 16t² + 96t + 112
= -16(3)² + 96(3) + 112
= -144 + 288 + 112
= 256
The maximum height is therefore 256 feet, and time needed to reach the height will be 3 seconds.
c. The maximum height has been calculated and it is 256 feet.
d. The time it take for the quarter to hit the water will be:
= 3 seconds × 2 = 6 seconds
Since the maximum height took 3 seconds, it would take another 3 seconds to hit the water. This makes it 6 seconds
A large box P containing 15 cans of biscuits weighs 23 kg and weighs 500g when empty. A box containing 8 cans of the same biscuits Q weighs 12.3kg. Box Q What is the mass when the box is empty?
Answer:
300 g
Step-by-step explanation:
weight of a can of biscuits= (23- 0.5)/15= 1.5 kg
weight of 8 cans= 1.5 * 8= 12 kg
mass of the empty box Q= 12.3- 12= 0.3 kg= 300 g
Answer:
300 g or 0.3 kg
Step-by-step explanation:
23 kg - 500g = 22.5 kg
each can of biscuits weighs 22.5 ÷ 15 = 1.5 kg
if the box Q weighs 12.3kg when there's 8 box of biscuits then
8 × 1.5 = 12 kg is the weight of biscuits and the remaining 300 g is box Q's weight

If the function m(x) has the point (1, 9) on its graph name a point that would be on the function 17n(x) + 2.
Answer: if we want to find a point of 17*m(x) + 2, one is (1, 155)
Step-by-step explanation:
I guess you want to know a point in the function
h(x) = 17*m(x) + 2
we know that m(1) = 9 (because m(x) has the point (1, 9) in it's graph)
then h(1) = 17*m(1) + 2 = 17*9 + 2 = 155
so this function has the point (1, 155)
The hypotenuse of right triangle ABC, line segment AC, measures 13 cm. The length of line segment BC is 5 cm. What is the approximate difference between m
Answer:
B) 44.8
Step-by-step explanation:
cos ( ∠C ) = 5/13 = 0.38462
m ∠C = cos^(-1) 0.38642 = 67.4°
m ∠A = 90° - 67.4° = 22.6°
m ∠C - m ∠A = 67.4° - 22.6° = 44.8°
Help me find these angles ASAP
Answer:
49°
Step-by-step explanation:
The sum of the exterior angles of a polygon = 360°
let x be the other exterior angle then sum and equate to 360
37 + 84 + 49 + 38 + 35 + 68 + x = 360
311 + x = 360 ( subtract 311 from both sides )
x = 49
The other exterior angle = 49°

Make b the subject of the formula a = square root b+6
Answer:
b = (a - 6)^2
Step-by-step explanation:
Solve for b:
a = sqrt(b) + 6
a = sqrt(b) + 6 is equivalent to sqrt(b) + 6 = a:
sqrt(b) + 6 = a
Subtract 6 from both sides:
sqrt(b) = a - 6
Raise both sides to the power of two:
Answer: b = (a - 6)^2
The formula is simplified as the equation b = a² - 6
Given data:
To make "b" the subject of the formula "a = √(b + 6)", we need to isolate "b" on one side of the equation.
Here are the steps to rearrange the equation and solve for "b":
Start with the equation: a = √(b + 6).
Square both sides of the equation to eliminate the square root:
(a)² = (√(b + 6))².
Simplify the right side of the equation:
a² = b + 6.
Subtract 6 from both sides of the equation to isolate "b":
a² - 6 = b.
So, the equation "a = √(b + 6)" can be rearranged as "b = a² - 6". This new equation allows us to calculate the value of "b" based on a given value of "a".
Hence, the equation is b = a^2 - 6.

Solve the equation -10x + 1 + 7 = 37
Answer:
-2.9
Step-by-step explanation:
-10x + 1 + 7 = 37
Combine like factors.
-10x + 8 = 37
Subtract 8 from both sides.
-10x = 29
Divide both sides by -10.
x = -2.9
Answer:
x = -29/10 = -2 9/10
Step-by-step explanation:
-10x + 1 + 7 = 37
Combine like terms
-10x +8 = 37
Subtract 8 from each side
-10x + 8-8 = 37-8
-10x = 29
Divide each side by -10
-10x/-10 = 29/-10
x = -29/10
x = -2 9/10

Radius r = 12/2 = 6 cm
Circumference = 2πr
= 2 * 3.14 * 6
= 37.68 cm
8) Distance around the track = 2 *circumference of semi circle + 80 + 80
= circumference of circle + 80 + 80
= 2 * 3.14 * 10 + 80 +80
= 62.8 +80 +80
