Answer:

The second object (4000 grams) had more kinetic energy

Step-by-step explanation:

Use the equation KE = 0.5mv², where m is the mass and v is the velocity.

Find the kinetic energy of the first object:

KE = 0.5(2000)(2 m/s)²

KE = 4000 J

Find the kinetic energy of the second object:

KE = 0.5(4000)(3 m/s)²

KE = 18000 J

So, the second object (4000 grams) had more kinetic energy.

The second object of mass 4000 grams will have more kinetic energy than the first mass.

The energy that an object has as a result of motion is known as kinetic energy. It is described as the effort required to move a mass-determined body from rest to the indicated velocity.

Use the equation KE = 0.5mv², where m is the mass and v is the velocity.

The kinetic energy of the first object:

KE = 0.5(2000)(2 m/s)²

KE = 4000 J

The kinetic energy of the second object:

KE = 0.5(4000)(3 m/s)²

KE = 18000 J

Therefore, the second object (4000 grams) had more kinetic energy.

Answer:

D. 63°

Step-by-step explanation:

a = 27°

b = 180° - (a + 27°)

b = 180° - (27° + 27°)

b = 180° - 54°

b = 126°

By inscribed angle theorem:

c = 1/2 b = 1/2 * 126°

c = 63°

The measure of angles a, b, and c in the given figure are 27°, 126°, and 63°, respectively.

An isosceles triangle is one with two equal-length sides. It is sometimes stated as having exactly two equal-length sides, and sometimes as having at least two equal-length sides, with the latter form containing the equilateral triangle as a particular case.

In the triangle ORQ, the two sides of the triangle OR and OQ are the radius of the triangle, therefore, the length of the two sides will be.

Since the two sides of the triangle are equal, therefore, the triangle will be an isosceles triangle, with the angle opposite to the same length measuring the same. Therefore,

∠OQR = ∠ORQ

a = 27°

Now, in a triangle, the sum of the measure of all the angles is equal to 180°. Therefore, we can write,

∠OQR + ∠ORQ + ∠QOR = 180°

a + 27° + b = 180°

27° + 27° + b = 180°

b = 180° - 27° - 27°

b = 126°

Further, In a circle, the measure of the angle formed by the chord in the centre of the circle is twice the measure of the angle formed by the same chord on any point in the circle. Therefore,

∠QOR = 2∠QPR

b = 2 × ∠QPR

126° = 2 × ∠QPR

∠QPR = 126° / 2

∠QPR = 63°

Hence, the measure of angles a, b, and c in the triangle are 27°, 126°, and 63°, respectively.

Step-by-step explanation:

Let money with gopal be x

let money with laxmi be y

Given

Gopal gives Rs 10 from his money to Laxmi her money becomes double thanthat of the remaining money of Gopal

Money left with gopal after giving Rs 10 = x-10

money with Laxmi after getting rs 10 = y+10

according to given condition

money with laxmi = 2*money left with Gopal

y+10 = 2(x-10)

___________________________________________________

Laxmi gives Rs 10 to Gopal his moneyis still Rs 10 less than the remaining money of Laxmi.

Money left with Laxmi after giving Rs 10 = y-10

money with Gopal after getting rs 10 = x+10

according to given condition

money with laxmi -10 =money  with Gopal

y-10-10 =x+10

y-20 = x+10

=> y = x+10+20

y = x+30

substituting y = x+30 in    y+10 = 2(x-10)

x+30 +10 = 2(x-10)

x+40 = 2x-20

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

========================================================

Explanation:

The domain is the set of allowed x values. In terms of a graph, we look at the left most point to see that x = -5 is the smallest x value possible. However, there's an open hole at this endpoint, so -5 itself is actually not part of the domain. So x must be larger than -5. At the same time, x can be as large as x = 3. Look at the very right tip of the graph to find this x value.

So x spans from -5 to 3, excluding -5 but including 3. We would write [tex]-5 < x \le 3[/tex] which converts to the interval notation (-5, 3]. Note the mix of curved parenthesis and square bracket. The curved parenthesis means to exclude the endpoint, while the square bracket means include the endpoint.

-----------

The range is the set of possible y outputs. Find out the lowest point of the graph. That is when y = -4 and this value is included due to the filled in circle at the endpoint. But we do not include the largest y value y = 5 as there's an open hole at this endpoint.

So the range is the set of y values such that [tex]-4 \le y < 5[/tex] which in interval notation would be written as [-4, 5)

-----------

So in short, you're looking for the min and max of x and y to get the domain and range respectively. Be sure to exclude any values where there are open holes as those do not count as part of the graph.

For a given function f(x), we define the domain as the set of the possible inputs for that function.

Here we will see that the domain is (-5, 3]

So, to find the domain by looking at a graph, we need to see the smallest x-value and the largest x-value.

In the graph, at the left, we can see that we have a white dot at x = -5

This means that the point itself does not belong to the domain, so here we need to use an open interval symbol, which is (

Then at the moment, we have:

domain = (-5

Now if we look at the right side, we can see that we have a black dot at x = 3.

This means that the value x = 3 belongs to the domain, so here we need to use the close symbol ].

Then the domain will be:

(-5, 3]

6:4:3.....................

The ratio between A, B, and C is 6:4:3.

To determine the ratio between A, B, and C based on the given information, we can set up the following equations:

2% of A = 3% of B

4% of C = 3% of B

Let's solve for the variables and find the ratio:

First equation: 2% of A = 3% of B

0.02A = 0.03B

A/B = 0.03/0.02

A/B = 1.5

Second equation: 4% of C = 3% of B

0.04C = 0.03B

C/B = 0.03/0.04

C/B = 0.75

Now, let's express the ratio A:B:C based on the ratios we found:

A:B = 1.5:1

B:C = 1:0.75

To obtain a common ratio, we can multiply both ratios by 4:

A:B = 6:4

B:C = 4:3

Combining these ratios, we have:

A:B:C = 6:4:3

Therefore, the ratio between A, B, and C is 6:4:3.

Answer:

speed of Jim's train = 35 mi/h

speed of Sarah's train = 35 +20 mi/h = 55 mi/hour

Step-by-step explanation:

Let the speed of Jim's train be x mi/h

Given, Sarah and Jim leave a train station at the same time traveling 20mi/h faster that Jim’s train.

speed of Sarah's train = x + 20 mi/h

we know distance = speed * time

time = 3 hours

distance traveled by Sarah's train = 3*(x+20) = 3x+60 miles

distance traveled by Jim's train = 3*x =  3x miles

It is not given that if trains are moving in same or opposite direction.

__________________________________

if they are travelling in same direction

Then, then distance between them = total distance traveled by

faster train -  total distance traveled by

slower train = 3x +60 -3x = 60 miles

which is wrong as the two trains are 270 miles apart

hence, they are travelling in opposite direction

In this case

distance between them = total distance traveled by

faster train +  total distance traveled by

slower train = 3x +60 + 3x = 6x + 60 miles

given that the trains are 270 miles apart

6x + 60 miles = 270 miles

6x = 270 - 60 = 210

x = 210/6 = 35

Thus, speed of Jim's train = 35 mi/h

speed of Sarah's train = 35 +20 mi/h = 55 mi/hour

Step-by-step explanation:

We can apply the Intersecting Secant-Tangent Theorem.

TV is the secant.

VW is the tangent.

VW² = VT × VU

(x+6)² = (5+x+4) × (x+4)

Combine the terms in bracket.

(x+6)² = (x+9)(x+4)

Expand brackets on both sides of the equation.

x²+12x+36=x²+13x+36

Subtract x² from both sides.

12x+36=13x+36

Subtract 12x from both sides.

36=x+36

Subtract 36 from both sides.

0=x

WV = x+6

x=0

WV = 0+6 = 6

The measure of the tangent WV is 6.

Answer: Y=60x

Step-by-step explanation:

find the slope (Y2-Y1)/(X2-X1)

                       (240-150)/4-2.5)

                        90/1.5 =60

It's multiple choice so it can only be a or b. If you do 60 x 2.5 you get 150 so there's no way you will add 480 so you are done it's A. If it's not a multiple choice question then you would do the who y=mx+b and plug in x, y and m and then find the b which in this case would be 0.

Answer:

(2.5,150)(4,240)

slope = (240 - 150) / (4 - 2.5) = 90 / 1.5 = 60

y = mx + b

slope(m) = 60

(4,240)...x = 4 and y = 240

now we sub and find b, the y int

240 = 60(4) + b

240 = 240 + b

240 - 240 = b

0 = b

so ur equation is : y = 60x + 0 which is written as : y = 60x <==

Perimeter of a rectangle = 2l + 2w

where

l is the length

w is the width

From the question

Perimeter = 24m

The statement

The length is 30 m less than five times the width is written as

l = 5w - 30

Substitute the expression into the above formula and solve for the width

That's

24 = 2( 5w - 30) + 2w

24 = 10w - 60 + 2w

84 = 12w

Divide both sides by 12

w = 7

Substitute this value into l = 5w - 30

That's

l = 5(7) - 30

l = 35 - 30

l = 5

Therefore the dimensions are

width = 7 m

length = 5 m
