Explain to me in words how you would find the slope of this line and explain answer
Answers
7/3
Explanation:
The slope of the line is equal to the rise/run, or in other words, the number of units the line travels upwards over the number of units the line travels to the right.
We can identify the slope using any two points on the line. Here, we can use the two points that are marked on the picture. The second point is 7 units above the first and 3 units to the right of the first, so the slope of the line is equal to 7/3.
Another way to calculate the slope of the line is the use this formula:
(y2-y1)/(x2-x1)
The first point is at the coordinate (1,-4) and second point is at the coordinate (4,3). When we plug these two coordinates into the equation, we get this:
(y2-y1)/(x2-x1)
->(3-(-4))/(4-1)
When we simply the fraction, we would get 7/3 and that would give us the slope.

there are 538 jelly beans in a bowl hector and Michael decided to share the jelly beans how many jelly beans do Michael and hector get? Their mom tells them they can not eat all the jelly beans at once. They can each eat an equal amount of jelly beans for four days. How many jelly beans do hector and Michael eat each day for four days
Answers
Answer:
67.25
Step-by-step explanation:
Since they can each get 1/2 the jelly beans but need to eat it over 4 days they will be eating 1/2*1/4 jelly beans per day. This is equal to 1/8x where x is the total jelly beans. We know the total so we can plug 538 in for x and divide 538 by 8 to get 67.25

The drawing is very poor because it shows that it’s an equilateral triangle but in the same time they made it confusing with using the degree sign on the variables..
Very confusing but the best way to do it is
Y+2x+1=180
Y=179-2x
Z+2x-1=180
Z= 181-2x
We found the previous but knowing that a straight line gives us 180
After that we equate all angles in the triangle to 180 (crazy eh?! Also definition of a triangle all angles make up 180)
X+179-2X+181-2X=180
-3x=180-181-179
X=60
Which gives us Y=59 and Z=61 from the equation we created in the beginning.

Given that the point X lies on AB produced so that AB : BX = 2 : 1, find x, the position vector of X, in terms of a and b. ii. If Y lies on BC, between B and C so that BY : Y C = 1 : 3, find y, the position vector of Y, in terms of a and b iii. Given that Z is the midpoint of AC, Calculate the ratio XY : Y Z.
Answers
i. The position vector of X is 2b - a.
ii. The position vector of Y is (3b + c)/4.
iii. The ratio XY : Y Z is \(|(2b - a) - ((3b + c)/4)|/|((3b + c)/4) - (a + c)/2|\). Simplifying this expression will give us the final ratio.
i. To find the position vector x of point X, we can use the concept of vector addition. Since AB : BX = 2 : 1, we can express AB as a vector from A to B, which is given by (b - a). To find BX, we can use the fact that BX is twice as long as AB, so BX = 2 * (b - a). Adding this to the vector AB will give us the position vector of X: x = a + 2 * (b - a) = 2b - a.
ii. Similar to the previous part, we can express BC as a vector from B to C, which is given by (c - b). Since BY : YC = 1 : 3, we can find BY by dividing the vector BC into four equal parts and taking one part, so BY = (1/4) * (c - b). Adding this to the vector BY will give us the position vector of Y: y = b + (1/4) * (c - b) = (3b + c)/4.
iii. Z is the midpoint of AC, so we can find Z by taking the average of the vectors a and c: z = (a + c)/2. The ratio XY : YZ can be calculated by finding the lengths of the vectors XY and YZ and taking their ratio. Since XY = |x - y| and YZ = |y - z|, we have XY : YZ = |x - y|/|y - z|. Plugging in the values of x, y, and z we found earlier, we get XY : YZ =\(|(2b - a) - ((3b + c)/4)|/|((3b + c)/4) - (a + c)/2|\).

A car going south 35 mi/hr speeds up when the speed limit changes. It takes 0.05 hours to accelerate at a rate of 200 mi/hr2. What is the car’s final velocity?
Answers
a)The value of acceleration will be 4.8 m/s²
b)The total distance travelled is 505 m.
a) As all the movement happens along a straight line, we need to define an axis only, which we call x-axis, being the positive direction the one followed by the car.
We can choose to place our origin at the location where the motorcycle was stopped at the side of the road (assuming that it is the same point for the car when it passes him), so our initial position is 0.
We can also choose our time origin to be the same as the instant that the motorcycle starts from rest, so t₀ = 0.
With these assumptions, and assuming also that the acceleration is constant, we can write two equations, one for the car (at constant speed) and the another one for the motorcycle, as follows:
xc = vx*t
xm= 1/2*a*t²
When the motorcycle passes the car, both distances traveled from the origin will be equal each other, i.e., xc = xm :
⇒ vx*t = 1/2*a*t²
We have as givens vx=35 m/s and t = 14.5 sec when both equations are equal each other.
⇒ 35 m/s* 14.5 s = 1/2*a*(14.5)²(s)²
Solving for a:
a = (2* 35 m/s) / 14.5 s = 4.8 m/s²
b) Replacing the value of a in the equation for xm, we have:
xm = 1/2*4.8 m/s²* (14.5)²s² = 505 m.

Arnav knows that (3,4,5) and (5,12,13) are pythagorean triples. He wants to show that (15,20,25) is also a pythagorean triple. Besides using the converse of the pythagorean theorem, is there another way Arnav can show that (15,20,25) is a pythagorean triple?
Answers
Answer:
easy do you want to get (15,20,25) from (3,4,5)and from(5,12,13)
Step-by-step explanation:
Arnav can use the fact that scaling doesn't affect the angles of a triangle, and that (3,4,5) is already stated being a Pythagorean triple.
What are similar figures?Similar figure are zoomed in or zoomed out (or just no zoom) version of each other. They are scaled version of each other, and by scale, we mean that each of their dimension(like height, width etc linear quantities) are constant multiple of their similar figure.
So, if a side of a figure is of length L units, and that of its similar figure is of M units, then:
M = k × L unitswhere 'k' will be called as scale factor.
The linear things grow linearly like length, height etc.
We're given that:
(3,4,5) is a pythagorean triple.
Let ABC be a right angled triangle possessing those sides (as the side lengths of a right angled triangle form pythagorean triple).
Scale each side of ABC by scale factor of 5, then we get:
(15, 20, 25) as a triple.
When scaling a figure, angles in it doesn't change because of angle being a relative quantity, not depending on the length of sides, but on the degree of rotation between two sides, which is unaffected because of scaling.
That means, that right angled triangle ABC, when scaled is still right angled triangle (because of its one of the angle 90 degrees still being 90 degrees in the new scaled triangle), but its sides are (15,20,25).
Now, since the triple (15,20,25) is side lengths of a right angled triangle, therefore, it is a pythagorean triple.
Thus, arnav can use the fact that scaling doesn't affect the angles of a triangle, and that (3,4,5) is already stated being a Pythagorean triple.

infinite number of solutions
Step-by-step explanation:
\(\frac{4}{5}\) (x + 9) - \(\frac{1}{5}\) x = \(\frac{3}{5}\) (x + 12)
multiply through by 5 to clear the fractions
4(x + 9) - x = 3(x + 12) ← distribute parenthesis on both sides

Answers
During halftime of a basketball game, a slingshot launches T-shirts at the crowd.
it takes the T-shirt 9/4 secondsThe maximum height of the T-shirt is 77 feet.What is the maximum height?
Generally, To find the time it takes the T-shirt to reach its maximum height, we need to find the time when the height of the T-shirt stops increasing and starts decreasing. At this point, the velocity of the T-shirt will be 0, since it is not moving up or down.
The velocity of the T-shirt at any time t can be found by taking the derivative of the equation for height:
v(t) = dh/dt = -32t + 72
Setting the velocity to 0 and solving for t, we get:
0 = -32t + 72 32t = 72 t = 72/32 t = 9/4
So it takes the T-shirt 9/4 seconds, or approximately 2.25 seconds, to reach its maximum height.
To find the maximum height, we plug this value back into the equation for height:
h(t) = -16(9/4)^2 + 72(9/4) + 4 h(t) = -81 + 162 + 4 h(t) = 77
The maximum height of the T-shirt is 77 feet.

part b - find the internal axial force in each bar segment using the answer for the support reaction at a determ
Answers
As per the axial force, the support reaction at A is equal in magnitude to the axial force that is applied at the other end of the bar.
To determine the support reaction at A, we will draw a free-body diagram of the bar.
Since the bar is fixed at A, the support reaction at that end will be a vertical force, and we will label it as RA.
Using Newton's second law of motion, we can write the equation of equilibrium for the bar in the vertical direction:
ΣFy = 0
where ΣFy is the sum of all the forces in the vertical direction. Since there are only two forces acting on the bar, the axial force and the support reaction, we can write:
-FA + RA = 0
where FA is the axial force that is applied at one end, and RA is the support reaction at the other end.
From this equation, we can solve for RA:
RA = FA

the following pair of triangles are similar. find the value of x 10 x x+2 x+14
Answers
The numerical value of x in the similar pair of triangle is 10.
What is the numerical value of x?A ratio is simply the relation between two amounts showing how many times a value is contained within another value.
From the diagram,
Side A of the small triangle = 10
Side B of the small triangle = x + 2
Side A of the Big triangle = 10 + x
Side B of the big triangle = x + 14
Hence;
Ratio of Side A to Side B of the small triangle = 10 / x + 2
Ratio of Side A to Side B of the Big triangle = 10 + x / x + 14
Since the triangle area similar, equate the two ratio and solve for x.
10 / ( x + 2 ) = ( 10 + x ) / ( x + 14 )
Cross multiply
10( x + 14 ) = ( 10 + x )( x + 2 )
Expand using FOIL method
10x + 140 = 10x + 20 + x² + 2x
10x + 140 = x² + 12x + 20
x² + 12x + 20 = 10x + 140
x² + 12x + 20 - 10x - 140 = 0
x² + 2x - 120 = 0
Factor the left side of the equation
( x - 10 )( x + 12 ) = 0
Hence;
x - 10 = 0 and x + 12 = 0
x = 10 and x = -12
Since the dimension of the triangle cannot be negative,
x = 10
Therefore, the value of x is 10.

Step-by-step explanation:
From the question we are told that
The number of trial is n = 7
The probability of success is p = 0.20
Generally the probability of failure is
\(q = 1- 0.20\)
\(q = 0.80\)
Given that this choices follow a binomial distribution as there is only two probabilities i.e success or failure
Then the probability is mathematically represented as
\(P(X = 0 ) = \left n} \atop {}} \right. C_0 * p^{0} * q^{n- 0}\)
\(P(X = 0 ) = \left 7} \atop {}} \right. C_0 * (0.2)^{0} * (0.8)^{7- 0}\)
Here \(\left 7} \atop {}} \right. C_0 = 1\)
=> \(P(X = 0 ) = 1 * 1* (0.8)^{7- 0}\)
=> \(P(X = 0 ) = 0.210\)
