The coordinates of the point P that partitions the Line N, into the ratio 1:5 is; P(x, y) = (-14/6), (-9/6)
How to partition line segment?We are told that the point P partitions the Line N, into the ratio 1:5.
Now, the coordinates of N and M are;
N(-3, -2), M(1, 1)
The formula to find the coordinates that partition a line is;
P(x, y) = (bx1 + ax2)/(a + b), (by1 + ay2)/(a + b)
where the ratio is a:b. Thus;
Thus, the coordinates of point P here are calculated as;
P(x, y) = (5*-3 + 1*1)/(1 + 5), (5*-2 + 1*1)/(1 + 5)
P(x, y) = (-14/6), (-9/6)

(a) The area of a rectangular field is 7546 m².
If the length of the field is 98 m, what is its width?
Width of the field: m
Answer:
77m
Step-by-step explanation:
Area of rectangle = L x W
7536m² = 98 x W
(Divide both sides by 98 to get W)
W = 7536m ÷ 98m
W = 77m

The correct option is a) x = negative two fifths. The value of x is obtained by solving it with rules of linear equation in two variable as x = -2/5.
What is linear equation in one variable?A linear equation in one variable is an equation that has only one solution and is expressed in the form ax+b = 0, where a and b are two integers and x is a variable. 2x+3=8, for example, is a linear equation with a single variable.
Now, as per the given expression;
2/3(x -2) = 4x
Multiply both sides of equation by 3.
2(x - 2) = 12x
Simplifying;
2x - 4 = 12x
Subtract 2x on both sides of the equations.
-4 = 12x - 2x
Again Simplifying;
-4 = 10x
Divided by 10 on both sides
x = -4 / 10
x = -2/5
Therefore, the value of x is obtained as x = -2/5.

Consider a physical pendulum with length of 94.7 cm and mass of 166 g. if the pendulum was released from an angle less than 10o, then calculate the angular speed of the pendulum. (g = 9.80 m/s2)
Angular velocity of pendulum is 3.216 rad/s.
What is angular velocity?In physics, the rotational velocity ( or ), also referred to as the angular frequency vector, is a pseudovector representation of how quickly an object's angular position or orientation varies over time (i.e. how quickly an object rotates or revolves relative to a point or axis). The pseudovector's direction is normal to the instantaneous plane of rotation or angular displacement, and its magnitude equals the rate at which the object is rotating or revolving. Traditionally, the right-hand rule is used to specify the direction of angular motion.
Orbital and spin angular velocities are the two forms of angular velocities.
For a small angle angular velocity of the pendulum is calculated as:
ω[tex]= \sqrt{\frac{g}{l} }[/tex]
Here, g= gravity acceleration and l = pendulum's length.
Conversation of unit of length are,
l=94.7 cm = 94.7 cm * ([tex]\frac{10^{-2}m}{1cm}[/tex]) = 0.947 m
Substitute l = 0.947 m and g = 9.80 [tex]m/s^2[/tex] in the expression ω[tex]= \sqrt{\frac{g}{l} }[/tex]
ω[tex]= \sqrt{\frac{9.80m/s^2}{0.947m} } = 3.216[/tex]

Write a difference quotient that best approximates the instantaneous rate of change of g at x=2.5.
A difference quotient that best approximates the instantaneous rate of change of g at x=2.5 is; -3
What is the Difference Quotient?We can define the average rate of change of a function g(x) in an interval [a, b] as:
r = [g(b) - g(a)]/(b - a)
Particularly, if we want to find an approximation of the rate of change for a particular value x', we can choose:
a < x' < b
Such that a and b are really close to x'.
Then if we want to find the instantaneous rate of change of g at x = 2.5, we need to find values of a and b really close to 2.5.
Looking at the graph, we can choose:
a = 2
b = 3
(are the two closer ones to 2.5)
Then the rate of change can be written as:
f'(x) = g(3) - g(2)]/(3 - 2)
f'(x) = (1 - 4)/1
f'(x) = -3
Thus, we can conclude that a good approximation of the instantaneous rate of change is -3.

Based on the number of students invited to the office and the number of Volleyball students who left, the number of students who were both prefects and volleyball players are 3 students.
Those who are only prefects are 4 students.
How many students are prefects?To find the number of students who were both prefects and volleyball players, the formula is
= Number of volleyball players who left + Total number of volleyball players - Number of students called to office
= 7 + 10 - 14

ILL GIVE BRAINLIEST!!!!!
Answer: 24
Step-by-step explanation:
t=seconds. h=height
t=3
h=3+55t-16t^2
h=3+55(3)-16(3)^2
h=3+165-16*9
h=168-144
h=24 ft
The ball's height 3 seconds after it was kicked is 24 feet above the ground.
Given that a formula h = 3 + 55t-16t² describes a ball's height above the ground h, which has been kicked vertically upward from a height of 3 feet with an initial speed of 55 feet per second.
We need to find the height of the ball after 3 seconds.
To find the ball's height 3 seconds after it was kicked, we can use the formula provided:
h = 3 + 55t - 16t²
where h represents the height in feet and t represents the time in seconds.
To find the height after 3 seconds (t = 3), plug the value into the formula and calculate:
h = 3 + 55(3) - 16(3)²
Now, perform the calculations step by step:
h = 3 + 55(3) - 16(9)
h = 3 + 165 - 144
h = 24 feet
Hence the required height is 24 feet.

If a line, line segment, or ray is perpendicular to a plane, it is perpendicular to every line, line segment, or ray in the plane that intersects it.
c. If a line is perpendicular to a plane, then every plane containing the line is perpendicular to the given plane. If line a is perpendicular to plane P , what must also be true?
The statement which must also be true is that: since line a is perpendicular to line P, any plane containing line a is perpendicular to line P.
What is a line?A line can be defined as a mark with length and direction, that is created by a point that is moving across a surface. Also, a line can vary in length, width, direction, curvature, and color.
What is a line segment?A line segment can be defined as the part of a line in a geometric figure such as a triangle, circle, quadrilateral, etc., that is bounded by two (2) distinct points and it typically has a fixed length.

Write an equation in slope-intercept form for the perpendicular bisector of the segment with the given endpoints. Justify your answer. (Lesson 5-1)
D(-2,4) and E(3,5)
The equation of the perpendicular bisector of the segment with the endpoints located at D(-2 , 4) and E(3 , 5) is y = -5x + 7
A perpendicular bisector of a segment is a line that divides the segment into two equal parts forming right angles at the point of intersection.
To get the perpendicular bisector of a segment, get the point of intersection of the two lines which is the midpoint of the segment.
midpoint (x , y) = [(x1 + x2)/2 , (y1 + y2)/2]
midpoint (x , y) = [(-2 + 3)/2 , (4 + 5)/2]
midpoint (x , y) = (1/2 , 9/2)
Get the slope of the perpendicular bisector of a segment by taking the negative reciprocal of the slope of the segment.
slope of segment = (y2 - y1)/(x2 - x1)
slope of segment = (5 - 4)/(3 - -2)
slope of segment = 1/5
slope of the perpendicular bisector = -5
Solving for the y-intercept, b, plug in the point (1/2 , 9/2) and the slope -5 to the slope-intercept form of the equation, y = mx + b.
y = mx + b
9/2 = -5(1/2) + b
b = 7
