Question:

The velocity function, in feet per second, is given for a particle moving along a straight line. [tex]v(t) = t^2 - t - 42[/tex]    [tex]1 \le t \le 12[/tex]

Find the displacement

Answer:

The displacement is 42.17ft

Step-by-step explanation:

Given

[tex]v(t) = t^2 - t - 42[/tex]    [tex]1 \le t \le 12[/tex]

The displacement x, is calculated using:

[tex]x = \int\limits^a_b {v(t)} \, dt[/tex]

[tex]x = \int\limits^{12}_{1} {t^2 - t - 42} \, dt[/tex]

Integrate

[tex]x = \frac{1}{3}t^3 - \frac{1}{2}t^2 - 42t|\limits^{12}_{1}[/tex]

Substitute 12 and 1 for t respectively

[tex]x = (\frac{1}{3}*12^3 - \frac{1}{2}*12^2 - 42*12) - (\frac{1}{3}*1^3 - \frac{1}{2}*1^2 - 42*1)[/tex]

[tex]x = (576 - 72 - 504) - (\frac{1}{3} - \frac{1}{2} - 42)[/tex]

[tex]x = (0) - (-42.17)[/tex]

[tex]x = 42.17[/tex]

Answer:

Simple solution for that!

4 : 5

Step-by-step explanation:

both 8 and 10 are divided by 2

8 ÷ 2 : 10 ÷2

4 : 5

further can't simplify so 4 : 5 is the answer

Answer:

50272

Step-by-step explanation:

Okay how I solve these equations is I take the problem apart like this:

3142 = 3000 + 100 + 40 + 2

Now we multiply each number by 16:

3000 * 16 = 48000

100 * 16 = 1600

40 * 16 = 640

2 * 16 = 32

Then we add all the totals together:

48000 + 1600 + 640 + 32 = 50272

Hope this Helps ;)

Answer:

25

Step-by-step explanation:

a^2 + b^2 = c^2

Here, c is the hypotenuse. We'll plug the given numbers into the equation, so we get:

15^2 + 20^2 = c^2

225 + 400 = c^2

625 = c^2

To undo a squared number, you find the square root of it:

[tex]\sqrt625[/tex] = 25

Your answer is 25! If you need more help, just ask :D

Answer:

[tex]\sqrt{10} \approx 3.2[/tex]

See attachment for number line where the dot represents 3.2

Step-by-step explanation:

Given

[tex]\sqrt{10}[/tex]

Required

Solve and plot on a number line

[tex]\sqrt{10}[/tex]

Using a calculator:

[tex]\sqrt{10} \approx 3.2[/tex]

So, 3.2 will be plotted on the number line, and it will be situated between 3 and 4 i.e: [tex]3 < 3.2 < 4[/tex]

Answer: 7.2 got the question right

Answer:

∠1 = 48°

∠2 = 132°

∠3 = 48°

Step-by-step explanation:

∠1 = (360-132-132)/2 = 48°

∠2 = 132° because it is the alternate angle to 132°

∠3 = 48° because it is the alternate angle to ∠1

Step-by-step explanation:

here's your solution

=> sum of ages of both A and B = 55

=> let the ratio be in x

=> now, ratio is 5x and 6x

=> a/q , 6x + 5x = 55

=> 11x = 55

=> x = 55/11

=> x = 5

age of A = 6*5 = 30 years

age of B = 5*5 = 25 years

Answer:

x  ≥  21

The second choice, 6(7x + 10)

Step-by-step explanation:

6(7x + 10)

6(7x) + 6(10) Distribute

42x + 60 Simplify

Answer:

6(7x+10)

Step-by-step explanation:

Hello There!

We can find an equivalent expression by factoring

First we need to find the greatest common factor (GCF)

GFC - largest number that both numbers can be divided by

Lets write down all of the multiples of each number

42 - 42 and 1, 21 and 2, 13 and 3, 6 and 7,

60 - 60 and 1, 30 and 2, 20 and 3, 4 and 15, 6 and 10

Then we find the greatest common factor which would be 6

42x/6=7x

60/6=10

so we can conclude that an equivalent expression would be

6(7x+10)

Answer:

Step-by-step explanation:

10% of 50 = 5

5% of 50 = 2.5

to get to 65 u do 5+5 = 10 so so far that is 20% but 20% only gets u to 60 so u add another 10% to reach 65

u have used 30% so the answer to yr question is 30%

Additional comment

The exact conversion between kg and pounds is 1 lb = 0.45359237 kg. The number 2.2 is approximate, low by approximately 0.21%.

Answer:

294

Step-by-step explanation:

14 x 9 = 126

so the area of your rectangle is 126.

15 - 9 = 6

so 6 is the width, 14 is the height.

14 x 6 = 84

now you have to multiply is by 2, because there is still another Triangle on the other side.

84 x 2 = 168

Now you take 168 and 126 and add your areas, and you have found the complete area!

168 + 126 = 294

I hope this helps! :)

Answer:wait it must be 30 for the product which means the answer is 26

Step-by-step explanation:

Answer:

-6 and 7

Step-by-step explanation:

x is one number and y is the other

(1)-----------------    8x+5y=-13

(2)------------------  x+y= 1

first, let multiply both sides of (x+y=-1) by 8

(3)-----------------    8x+8y=8

lets subtract (1) from (3)

(8x+8y)-(8x+5y)=8-(-13)=3y

8-(-13)=3y ->  21=3y

y=7

lets plug in 7 into (2) for x

x+7=1

x=-6

the numbers are -6 and 7
