Area of triangles and quadrilaterals

Mathematics
1 answer:
pishuonlain [190]3 years ago
5 0
Formulas needed:

Square area = b^2
Rectangle area = bh
Triangle area = bh/2
Parallelogram = bh
Trapezoid area = a+b/2(h)
Rhombus area = pq/2

Even better; use online calculators.
To use these formulas, you need to substitute the values given for b,h,a,b,p or/and q and then solve to get area.

So for this example, since it's a rectangle, you use formula A = bh. Base is 5.1, and height is 6.

Substitute now.

A = bh
   = (5.1)(6)  (substitute)
   = 30.6       (multiply)

Therefore the area is 30.6 m^2. Don't forget the unit measurements, which is *measurement*^2.

Explain the process for determining sales tax and total purchase price.
rewona [7]

Answer:

Multiply the decimal for the percent of tax by the purchase price, then add the amount of tax to the price to find the total price.

Step-by-step explanation:

Sales tax is an amount added to a price to get the total.

We multiply by the decimal for the percent; this means we divide the percent by 100 before we multiply.

Once we multiply, this gives us the amount of sales tax.  We add this to the price of the item to get the total purchase price.

What is the geometric mean of 4 and 10
GalinKa [24]

Answer: 6.3

Step-by-step explanation:

The formula for geometric mean is given as :

G.m = \sqrt{pq}

Therefore , the geometric mean between 4 and 10 will be :

G.m = \sqrt{4(10)}

      = \sqrt{40}

      = 2\sqrt{10}

     = 6.3

Given an acceleration vector, initial velocity u0,v0,w0 , and initial position x0,y0,z0 , find the velocity and position vectors
dsp73

Answer:

Thus we find that velocity vector at time t is

(5t+15, 5t^2/2, 4t^2)

Step-by-step explanation:

given that acceleration vector is a funciton of time and at time t

a(t) = (5,5t, 8t)

v(t) can be obtained by integrating a(t)

v(t) = (5t, 5t^2/2, 4t^2)+(u_0,v_0,w_0)\\=(5t+15, 5t^2/2, 4t^2)

Thus we use the fact that acceleration is derivative of velocity and velocity is antiderivative of acceleration.

The arbitary constant normally used for integration C is here C vector = initial velocity (u0,v0,w0)

Position vector can be obtained by integrating v(t)

Thus we find that velocity vector at time t is

(5t+15, 5t^2/2, 4t^2)
