What do I do on this?

stiks02 [169]

All you do is measure it with a ruler and for every 1 cm you get multiply it by 8.5ft.
so for example if you got 6cm then you would multiply it by 8.5ft and your answer would be 51ft.

Subtract: (2x^2-7x+5)-(-6x^2-4x-2)

Wittaler [7]

Answer:

$\large\boxed{D.\ 8x^2-3x+7}$

Step-by-step explanation:

$(2x^2-7x+5)-(-6x^2-4x-2)\\\\=2x^2-7x+5-(-6x^2)-(-4x)-(-2)\\\\=2x^2-7x+5+6x^2+4x+2\qquad\text{combine like terms}\\\\=(2x^2+6x^2)+(-7x+4x)+(5+2)\\\\=8x^2-3x+7$

Derek’s bike has a mass of 12 kg and he is riding at a velocity of 8 m/s. What is the kinetic energy of the bike

Marrrta [24]

Answer: The kinetic energy of Derek's bike is 384.

To find the kinetic energy of an object, we need to know the mass and the velocity of the object. Both of those are already given in the problem. So we can simply use the formula.

The formula for kinetic energy is KE =0.5(m)v^2. All we need to do is input the know variables and evaluate.

KE = 0.5 (12) (8^2)
KE = 0.5(12)(64)
KE = 384

What is the area of the composite figure whose vertices have the following coordinates? (−1, 5) , (3, 5) , (7, 3) , (3, 0) , (−1

trasher [3.6K]

We can see the figure as two triangles and a square.
We have then:
Area of the square:
A1 = (4) * (4)
A1 = 16
Area of the small triangle:
A2 = (1/2) * (4) * (1)
A2 = 2
Area of the big triangle:
A3 = (1/2) * (5) * (4)
A3 = 10
The area of the figure is:
At = A1 + A2 + A3
At = 16 + 2 + 10
At = 28units²
Answer:
The area of the figure is:
At = 28units²
