Answer:

a. greater than 75 J

Step-by-step explanation:

Potential Energy at the top = mgh

Mass m = 2kg

g = 9.8m/s^2

height h  = 10m

Potential Energy at the top = 2 * 10 * 9.8

Potential Energy at the top = 196Joules

The object is not moving at the bottom, hence the KE of the body at the bottom is 0Joules

difference between the PE at the top and the KE at the bottom = 196 - 0 = 196Joules

Hence the difference between the PE at the top and the KE at the bottom is greater than 75Joules

[tex]40 \times 0.80 = 32[/tex]

He gains £384

[tex]40 - 32 = 8[/tex]

[tex]8 \div 2 = 4[/tex]

[tex]2(12) + 2(6) = 36[/tex]

He gains £36

[tex] - 130 + 384 + 36 = 290[/tex]

Ryan made £290

I'm not too sure about this...

Anyway if he sold 80% of the jumpers at a normal price, he would earn £384.

There are 8 left and he managed to sell half of those but there is a promo where you can buy one at full price and get one for half the price so only two of the four can be bought at full price while the other two gets bought at half price. He earns £36 from this.

If you take in account the starting cost and add the profits, he made a total of £290 selling jumpers.

But again, I'm not too sure.

Answer:

In the form of (x,y) there are 2 solutions:

(-3,4)

(-24/5, -7/5)

Step-by-step explanation:

First isolate one of the letters (for me I'm using the y of equation 2 because it's easier to solve)

[tex]y-3x=13\\y=13+3x[/tex]

Now that we have y isolated, substitute y in equation 1 with the equation we got previously (y=13+3x)

[tex]x^2+(13+3x)^2=25[/tex]

Now simplify:

[tex]x^2+(13+3x)^2=25\\x^2+9x^2+78x+169=25\\10x^2+78x+169=25[/tex]

Now turn the equation into ax^2+bx+c=0 form by transferring 25 to the other side of the equation:

[tex]10x^2+78x+169=25\\10x^2+78x+169-25=0\\10x^2+78x+144=0[/tex]

Using the quadratic formula we will have the 2 following values:

[tex]x=-3[/tex]

[tex]x=-\frac{24}{5}[/tex]

Substitute the following values into any equation you want (this time I'll pick equation 2 again since its the easiest to solve)

[tex]y-3x=13\\y-3(-3)=13\\y-(-9)=13\\y+9=13\\y=13-9\\y=4[/tex]

[tex]y-3x=13\\y-3(-\frac{24}{5})=13\\y-(-\frac{72}{5})=13\\y+\frac{72}{5}=13\\y=13-\frac{72}{5}\\y=-\frac{7}{5}[/tex]

Answer:

the tree is 8.8 m tall

I can't draw it but it will be two similar acute triangles. The one that represents the man will have a 2m height and a 5m base. The one that represents the tree will have an 8.8m height and a 22 m base.

Step-by-step explanation:

it's a proportional relationship

5/22=2/height

5(height)=2(22)

5(height)=44

divide both sides by 5

5(height)/5=44/5

height=8.8 m

Answer:

X=-4

Step-by-step explanation:

-2x + 4 = 12

so what you would do is subtract 4 from itself and 12

4 - 4 = 0

12 - 4 = 8

then we have-

-2x = 8

we then divide 2 from 2 and 8

2 divided by 2 = 0

2 divided by 8 = 4

so x = -4

Answer:

3579.6 [tex]ft^{3}[/tex]

Step-by-step explanation:

First, write out the equation used to find the volume of a cylinder and place the values in place of the variables. The equation is [tex]\pi[/tex][tex]r^{2}[/tex]*h where r is the radius and h is the height. When we place the values of the variables into the equation we get: [tex]\pi[/tex][tex]10^{2}[/tex]*11.4. Next, square 10 to get 100. This would give you 3.14*100*11.4. When you multiply this together you get 314 times 11.4 which gives you 3579.6 ft cubed.

I believe it's 3581.42 (if the answer needs be rounded to 2 decimal places.

Step-by-step explanation:

area of circle = r×r×π

area of circle × height = volume

10 × 10 × π = 314.16

314.16 × 11.4 = 3581.42

Answer:

D. y = 6x – 5​

Step-by-step explanation:

Red: 6x – 2y = 10

Blue y = 6x – 5​

The line {y} = 6x - 5 will intersect the line 6x – 2y = 10 exactly at one point.

The general equation of a straight line is -

y = mx + c

where -

{m} is the slope of the line.

{c} is the {y} - intercept.

Given is to find the equations that will intersect the graph of (6x - 2y = 10) exactly once.

The equation of a straight line given is -

6x - 2y = 10

2y = 6x - 10

y = 3x - 5

The lines -

{y} = 3x- 10

{y} =3x - 5

{y} = 3x – 1

are parallel to the line {y} = 3x - 5 as their slopes are equal. So, these 3 equations will not intersect.

Therefore, the line {y} = 6x - 5 will intersect the line 6x – 2y = 10 exactly at one point.

Answer:

B. d(t) = 9t; 23.22 ft

Step-by-step explanation:

m= minutes  

2.58*m  

2.58*9=23.22

The snail will travel 23.32 feet in 9 minutes.

Answer

As given

A snail travels at a rate of 2.58 feet per minute.

First write a rule to describe the function.

Let a is denoted the distance.

t is the time

Thus the function becomes

a =  2.58 × t

a = 2.58t

This denoted the distance travelled in t time.

Second how far will the snail travel in 9 minutes .

Put t = 9 mintues in the above equation.

a =  2.58 × 9

a = 23.22 feet

Therefore the distance travelled in 9 mintues are  23.22 feet .

2.58m

So, in m you write the minutes.

2.58*9=23.22 feet per minute
