Answer:

Step-by-step explanation:
According to a Manila police, two people were killed when the 1,000 kg car illegally drag racing at a speed of 30 m/s had a head on collision with a 2,000 kg truck whose driver fell asleep as it traveled 20 m/s. Which vehicle has received the greater force?
Answers
Answer: To determine which vehicle received the greater force, we need to calculate the momentum change for each vehicle during the collision. The force experienced by a vehicle during a collision is equal to the rate of change of its momentum.
First, let's calculate the initial momentum for each vehicle:
The car has a mass of 1,000 kg and a velocity of 30 m/s, so its initial momentum is 1,000 kg * 30 m/s = 30,000 kg m/s.
The truck has a mass of 2,000 kg and a velocity of 20 m/s, so its initial momentum is 2,000 kg * 20 m/s = 40,000 kg m/s.
Next, let's calculate the final momentum for both vehicles after the collision:
The car and truck collide head-on, so their velocities will become zero after the collision. So the final momentum for both vehicles will be zero.
Finally, we can calculate the rate of change of momentum for each vehicle:
The rate of change of momentum for the car is equal to its final momentum minus its initial momentum, or 30,000 kg m/s - 0 kg m/s = 30,000 kg m/s.
The rate of change of momentum for the truck is equal to its final momentum minus its initial momentum, or 0 kg m/s - 40,000 kg m/s = -40,000 kg m/s.
Since the magnitude of the rate of change of momentum for the truck is greater than the magnitude of the rate of change of momentum for the car, the truck has received the greater force.
Step-by-step explanation:
a line y = 3x - 5 is reflected in x = a so that the image is given by y = 1 - 3x. what is the value of A?
Answers
Answer: The line y = 3x - 5 can be expressed in the form y = mx + b, where m is the slope and b is the y-intercept. In this case, m = 3 and b = -5.
When a line is reflected across the x-axis, the slope of the line changes sign, but the y-intercept remains the same. This means that if the original line has slope m and y-intercept b, the reflected line will have slope -m and y-intercept b.
For the image, y = 1 - 3x, the slope is -3 and the y-intercept is 1.
To find the value of a, we can set the two lines equal to each other and solve for x:
3x - 5 = 1 - 3x
Solving for x, we get:
4x = 6
x = 3/2
So the line of reflection, x = a, passes through

The "magic number" in baseball is used to estimate how likely a club is to advance to the postseason or win the division. Every year, in September, when teams get closer to clinching, it gains attention. The total number of victories and losses that must occur by a team's closest rival in order for that team to achieve a certain goal is known as its magic number. A team's magic number drops by one with each victory. The magic number additionally drops by one each time the team's closest rival for the division (or Wild Card) loses.
This is the precise formula: Games left in season: +1 (Losses by second place team - losses by first place team)
The magic number changes to reflect any further changes in the second-place team.

Is finding 9/8, subtracted by 1/2 the same as finding 9/10 subtracted by 1/4 subtracted by 1/4 ? explain .
Answers
9/8 - 1/2
To subtract two fractions, we need to have a common denominator. The common denominator of 8 and 2 is 8. We can rewrite 1/2 as 4/8:
9/8 - 4/8 = 5/8
Now let's evaluate the second expression:
9/10 - 1/4 - 1/4
To subtract 1/4 from 9/10, we need a common denominator of 4 x 10 = 40:
9/10 - 10/40 - 10/40 = 18/20 - 10/40 - 10/40 = 18/20 - 1/4 - 1/4 = 9/10 - 1/2

Do leading zeros count as significant figures?
Answers
Absolutely, because they show how big a number is, average leading zeros are regarded as significant digits. Leading zeros are counted as important figures since they help determine the decimal point's location and the size of the number.
Leading zeros in a number are important figures. This implies that when counting the total number of significant figures in a number, they are taken into account. The reason for this is that preceding zeros reveal the location of the decimal point and, hence, the size of the number. Because the leading zero signifies that the number is in hundredths, the number 0.002, for instance, has three significant figures. The number would be read as two rather than two hundredths without the leading zero. Due to their significance in assessing a number's precision, leading zeros should always be counted among the significant figures.

The false statement is (a) P( A^c n B^c)=P(A^c) P(B^c). The probability of the intersection of complements is generally not equal to the product of individual complements.
The misleading assertion including p, and the erratic occasions An and B is (a) P( A^c n B^c)=P(A^c) P(B^c).
This assertion is bogus in light of the fact that by and large, the likelihood of the convergence of the supplements of two occasions, A^c and B^c, isn't equivalent to the result of their singular supplements.
For instance, assume we flip a fair coin. Let A be the occasion of getting heads and B be the occasion of getting tails. Then, P(A) = P(B) = 1/2, so P(A^c) = P(B^c) = 1/2. In any case, A^c and B^c are a similar occasion (getting heads or tails, separately), so P(A^c n B^c) = P(A^c) = 1/2. Then again, P(A^c) P(B^c) = (1/2)(1/2) = 1/4, which isn't equivalent to P(A^c n B^c).

Suppose v varies directly as g, meaning that there is a constant k such that v = kg. If v = 70 when g = 30, then we can use this information to find the value of k:70 = k * 30k = 70 / 30k = 7 / 3Now that we have the value of k, we can use it to find v when g = 9:v = kgv = (7 / 3) * 9v = 21So when g = 9, v = 21.In conclusion, by finding the value of the constant of proportionality k and using the formula v = kg, we determined that when g = 9, v = 21.

Answers
{2x + y = 2
{5x + 3y - 9
Solution: We can solve this system of equations either by substitution or elimination method. Here, let's use substitution method.
From equation 1, we have: y = -2x + 2
Substituting this in equation 2, we get: 5x + 3(-2x + 2) - 9 = 0
Expanding the right-hand side, we get: 5x - 6x + 6 - 9 = 0
Simplifying further, we get: -x + (-3) = 0
Adding x to both sides, we get: -3 = x
Substituting this value of x in y = -2x + 2, we get: y = -2(-3) + 2 = 6
So, the solution to the system of equations is (x, y) = (-3, 6)
{5x - 2y = -2
{3x + 4y - 30
Solution: We can solve this system of equations by either substitution or elimination method. Here, let's use elimination method.
We can multiply equation 1 by 3 and equation 2 by 2, to make the coefficients of y same in both equations. Doing this, we get:
15x - 6y = -6
6x + 8y - 60 = 0
Adding these two equations, we get: 21x + 2y - 60 = 0
Simplifying further, we get: 21x = 60 + 2y
Dividing both sides by 21, we get: x = (60 + 2y)/21
Substituting this in equation 1, we get: 5((60 + 2y)/21) - 2y = -2
Expanding the right-hand side, we get: 60/21 + 10/21 y - 2y = -2
Simplifying further, we get: 60/21 + (-12/21) y = -2
Adding 12/21 y to both sides, we get: 60/21 = (-2) + (12/21) y
Subtracting -2 from both sides, we get: 62/21 = (12/21) y
Dividing both sides by 12/21, we get: y = 62/12 = 5 1/6
Substituting this value of y in x = (60 + 2y)/21, we get: x = (60 + 2(5 1/6))/21 = (60 + 11 1/3)/21 = (71 1/3)/21 = 71/21 + 1/63
So, the solution to the system of equations is (x, y) = (71/21 + 1/63, 5 1/6)
