10.An object of mass 300 kg is observed to accelerate at the rate of 4 m/s2. Calculate the force required to produce this
acceleration
PLLLLSSSSS HHHHHEEEELLLLPPPP
Answer:
F=Ma
Step-by-step explanation:
force= 300x4
force= 1200N
The Force required to move a mass of 300 kg is 1200 N
What is force?In Physics, force is defined as The push or pull on an object with mass that causes it to change its velocity. Force is an external agent capable of changing a body's state of rest or motion. It has a magnitude and a direction.
Given here, the mass (M) = 300 kg and acceleration = 4 m/s²
Therefore force required to move a body of mass 300 kg is
F=300×4
= 1200N
Hence, the for required to produce this acceleration is 1200N

Suppose a test of significance desires to see if there is a difference in mean SSHA scores between men and women. Which is the appropriate alternative hypothesis?
a. The population mean for women equals the population mean for men.
b. The population mean for women does not equal the population mean for men.
c. The population mean for women is greater than the population mean for men.
d. The population mean for women is less than the population mean for men.
Answer:
The correct option is b.
Step-by-step explanation:
A null hypothesis is a sort of hypothesis used in statistics that intends that no statistical significance exists in a set of given observations.
It is a hypothesis of no difference.
It is typically the hypothesis a scientist or experimenter will attempt to refute or discard. It is denoted by H₀.
For instance, H₀: µ = µ₀, where µ₀ is some null value or some claimed value.
Whereas, the alternate hypothesis is the contradicting statement to the null hypothesis.
The alternate hypothesis describes direction of the hypothesis test, i.e. if the test is left tailed, right tailed or two tailed.
It is also known as the research hypothesis and is denoted by Hₐ.
The research statement is:
"If there is a difference in mean SSHA scores between men and women."
Then the appropriate alternative hypothesis will be:
Hₐ: The population mean for women does not equal the population mean for men, i.e. μ₁ ≠ μ₂
The correct option is b.

Answer:
Step-by-step explanation:
angle A + angle B + angle C = 180° [Sum of all angles of a triangle is 180°]
=> 2x+1 + x+15 + x = 180°
=> 4x + 16 = 180°
=> 4x = 180° - 16°
=> 4x = 164°
=> x = ([tex]\frac{164}{4}[/tex])°
=> x = 41°
[tex]\\[/tex]
angle A = 2x+1 = 2×41 +1 = 82 + 1

Fomular for finding perimeter area and circumference of a circle
Answer:
perimeter of a circle=2πR
The perimeter of a circle is the circumference of the circle.
CIRCUMFERENCE
There are two formulas:
1. C = πd (use if the problem gives you the diameter only)
2. C = 2πr (use if the problem gives you the radius only)
AREA
There are several area formulas for a circle but I think for you at your level of math, A = πr^2 is all you need to know.
Given the figure below, find the values of x and z.
x =
(13x + 30)
z =
(12x + 50)
Answer:
x = 4
z = 92°
Step-by-step explanation:
From the picture attached,
Two straight lines are intersecting each other at a point so that,
(12x + 50)° + (13x + 30)° = 180° [Linear pair of angles]
25x + 80 = 180
25x = 100
x = 4
Therefore, measure of (13x + 40)° = 13×4 + 40
= 52 + 40
= 92°
Since, z° = (13x + 40)° [Vertically opposite angles]
Therefore, z° = 92°

point P lies on the origin of a coordinate system. if you translate the point 5 units up, then 4 units left, then 4 units down, the result is point P. what are the coordinates of point P
Answer:
The coordinates of point P after all the translations become: (-4, 1)
Step-by-step explanation:
The point P lies on the origin of a coordinate system.
i.e. P(0, 0)
Translating point 5 units up will translate the coordinates from (0, 0) to :
(x, y) → (x, y+5)
(0, 0) → (0, 0+5) = (0, 5)
THEN
Translating point 4 units left will translate the coordinates from (0, 5) to :
(x, y) → (x-4, y)
(0, 5) → (0-4, 5) = (-4, 5)
THEN FINALLY
Translating point 4 units down will translate the coordinates from (-4, 5) to :
(x, y) → (x, y-4)
(-4, 5) → (-4, 5-4) = (-4, 1)
Therefore, the coordinates of point P(0, 0) after translating point 5 units up, then 4 units left, then 4 units down will be:
(x, y) → (x, y+5) → (x-4, y+5) → (x-4, y+5-4)
(0, 0) → (0, 0+5) → (0-4, 0+5) → (0-4, 0+5-4) = (-4, 1)
Hence, the coordinates of point P after all the translations become: (-4, 1)

Which graph represents points on the polar curve r = 2 + 5sin(θ)?
Answer:
Graph 2
Step-by-step explanation:
See image attached. Hope this helps.
The second graph shown the polar curve at r = 7.
Given ,
Equation of polar curve = r = 2 + 5sin(θ)
We have to find ,
Which of following graph show polar curve ,
At r = 2 + 5sin(θ)
The area between two curves in the polar coordinate system, first find the points of intersection, then subtract the corresponding areas.
First graph ; r = 2 + 5sin(θ)
Where ,
[tex]\theta = 0[/tex]
r = 2 + 5sin0
r = 2 + 5 (0)
r = 2
Second graph : r = 2 + 5sin(θ)
Where
[tex]\theta = \frac{\pi }{2}[/tex]
Then,
r = 2 + sin[tex]\frac{\pi }{2}[/tex]
r = 2 +5 ( 1 )
r = 2+5
r = 7
Third graph ; r = 2 + 5sin(θ)
where
[tex]\theta = \pi[/tex]
Then,
r = 2 + 5sin[tex]\pi[/tex]
r = 2 + 5(0)
r = 2
Fourth graph ; r = 2 + 5sin(θ)
Where
r = 2 + 5sin[tex]\frac{3\pi }{2}[/tex]
r = 2 + 5 (-1)
r = -3
Fifth graph ; r = 2 + 5sin(θ)
Where
[tex]\theta = 2\pi[/tex]
r = 2 + 5sin(2π)
r = 2+ 5 (0)
r = 2
Comparing all the value of the graph ,the second graph shown the polar curve at r = 7.
Hence, The second graph shown the polar curve at r = 7.

Answer:
a) x=0, x=1
b)x=0, x=4/3
Step-by-step explanation:
I didnt use the graph, just used algebra. For part a, you can find the answers using the graph by looking at the value of x when y = whatever value they give.
A)
3x²-3x+2=2
3x²-3x+0
x(3x-3)=0
For the product of two things to equal zero, one of them has to be zero. For example, if ab=0, then either a or b (or both) are zero.
Therefore..
x=0
or 3x-3=0, ∴x=1
b)
3x²-3x-1 = x-1
3x²-4x=0
x(3x-4)=0
∴x=0, x=4/3

Suppose the line of best fit is drawn for some data points. If the mean of the
x-coordinates of the points is 5, and the mean of the y-coordinates of the
points is - 7 the line must pass through which of these points?
A. (-7,5)
B. (7-5)
C. (5, -7)
D. (-5,7)
the correct answer must be option C, which has the coordinates (5, -7), matching the centroid of the data points. Thus, the line of best fit passes through the point (5, -7).
How to find the coordinates?
To determine which point the line of best fit passes through, we need to use the fact that the line passes through the centroid of the data points. The centroid is the point (mean of x-coordinates, mean of y-coordinates).
Given that the mean of the x-coordinates is 5 and the mean of the y-coordinates is -7, the centroid is (5, -7). Therefore, we need to look for the point among the given options that has coordinates (5, -7).
The point (5, -7) is not listed as an option, but we can find the point that is closest to it.
Option A (-7,5) has the coordinates switched, so it cannot be the correct answer. Option B (7-5) is not a valid point since it is missing a comma between the x and y coordinates. Option D (-5,7) has the correct x-coordinate but the wrong y-coordinate.
Therefore, the correct answer must be option C, which has the coordinates (5, -7), matching the centroid of the data points. Thus, the line of best fit passes through the point (5, -7).
