Answer:
Concept: Physics Qualitative Analysis.
- Scalar values are constant and compared to vector values they do not have a direction or magnitude or a gradient representation.
- Lets get started by setting up the equation
- They want us to find 3U-2V
- Given U= <6,6> V=<6,-6>
- Now we plug in and solve!
- 3<6,6>- 2<6,-6>
- <18,18>-<12,-12>
- Subtract
- <18-12,18-(-12)>
- Hence that gives us a result of <6,30>
- Now with the skills you gained solve the rest!!!
Answer:
<h2>
</h2>
Step-by-step explanation:
Expand the terms in the bracket and simplify
That's
Using the subtraction property subtract 10x from both sides of the equation
<u>Add 6 to both sides of the equation</u>
<u>Divide both sides by 8</u>
<u>Reduce the fraction with 2</u>
We have the final answer as
Hope this helps you
I'm assuming you meant to say f(x) = 3x^2. If that assumption is correct, then the degree is found by multiplying the leading terms from both f(x) and g(x). The leading terms are 3x^2 and 4x^3
3x^2*4x^3 = (3*4)*(x^2*x^3) = 12x^(2+3) = 12x^5
The exponent of that result is 5, so the degree of (f*g)(x) is 5
Answer: 5
Area of a triangle = base x height / 2
64 = base x height / 2
(multiply 2 on both sides)
128 = base x height
then if base= 16 and height = 8 then 16 x 8 = 128
thus the base is 16 which is twice the height:8
You add two equations together to eliminate a variable. This particular problem is nice, because it's already setup to eliminate X.
3x - 4y = 9
<span>-3x + 2y = 9
</span>
When we add these two together, 3x - 3x cancels each other out, leaving us with 0x, or nothing.
We continue with -4y + 2y (leaves us with -2y) and 9+9 (18).
-2y = 18
18/-2 = -9.
Now we have y = -9, and we can go back into the problems to solve for x.
<span>3x - 4(-9) = 9
</span>
3x + 36 = 9.
3x = -27
x = -9.
Confirm with the final equation:
-3(-9) + 2(-9) = 9
27 - 18 = 9
9 = 9 --- Confirmed.
