You can use this formula: <span>vf^2=0+2(9.8)(M) 
solve it out like so:
vf^2=0+2(9.8)(180)
vf^2=2(1764)
vf^2=3528
now, square both sides to cancel out the power of 2. you are left with:
about 59.4 m/s</span>

V^2 = initial velocity^2 + 2* acceleration * distance

v^2 = (0m/s) + 2* 9.8 m/sec^2 * 180 m

v^2 = 3528 m^2 / sec^2

v = 59.397 m/sec

A 15-meter by 23-meter garden is divided into two sections. Two sidewalks run along the diagonal of the square section and along
Thepotemich [5.8K]

Solution:

We have re-drawn the given diagram, as we can see the given rectangle is actually divided into two parts.

one is Large square and the other one is a smaller rectangle.

Now we will apply the Pythagoras theorem in the larger triangle which is inside the square.

So we can write

Diagonal_1=\sqrt{15^2+15^2}= 21.213

Now we will apply the Pythagoras theorem in the smaller  triangle which is inside the smaller rectangle.

So we can write

Diagonal_2=\sqrt{15^2+8^2}= 17

The approximate sum of the lengths of the two sidewalks, shown as dotted lines=21.2+17=38.2 m

Hence the correct option is D

A business owner has two loans from the local bank. One of the loans is a three-year loan with a principal of $75,000 and an ann
vagabundo [1.1K]

Answer:


Step-by-step explanation:

One loan from the local bank is a three year loan with a capital of $75000 and an annual interest of 5%.

Therefore simple interest form this loan for the year will be

⇒ Principal amount×Rate of interest×Time(in years)/100

⇒ 75000×5×1/100

Interest = $3750

Other loan is a one year loan with a principal of $21000 and annual interest of 4.5%

Therefore interest of first year from this loan will be

= Principal amount×Rate of interest×Time(in years)/100

= 21000×5×4.5/100

= $4725

Total interest of first year for both loans = 3750+4725 = $8475

What equation is graphed in this equation?
jenyasd209 [6]
Y-2=-3/2(x-2)
first of all, the slope of the line is -3/2, and there's only one equation that has that as a choice for the slope. Then you can take the x and y coordinates given in that equation you want to check and see if the line goes through that point. from the equation, (point-slope form y-y=m(x-x)) I know that the line should pass through point (2, -2), and looking at the graph, that is correct.

-5/7 - -6/7z &lt; -2/7 how do I make this into a decimal
Xelga [282]
-5/7 - (-6/7)z < -2/7
-5/7 + 6/7z < -2/7
6/7z = -2/7 + 5/7 = 3/7
z = 3/7 / 6/7 = 3/7 x 7/6 = 3/6 = 0.5
z = 0.5
