Answer: 591
Step-by-step explanation:
12 x 13= 156
12 x 5= 60 x 2= 120
12 x 5= 60/2= 30 x2= 60
5 x 12= 60
13 x 15= 195
195 + 60 + 60 + 120 + 156= 591
Answer:
<em><u>Since we know the dot product of unit vectors, we can simplify the dot product formula to a⋅b=a1b1+a2b2+a3b3. we can use the same formula, but with a3=b3=0, a⋅b=a1b1+a2b2.</u></em>

Answer:
A. The center of dilation is point C.
B. It is a reduction.
E. The scale factor is 2/5.
Step-by-step explanation:
The center is shown as C. You can see this from the line segments they drew through C, the image, and the pre-image.
The pre-image is the image before the dialation. The pre-image here is XYZ.
The image is the image after dialation. The image is X'Y'Z'.
If you look at the pre-image XYZ and then it's image X'Y'Z', ask yourself the image get smaller or larger. To me I see a larger triangle being reduce to a smaller triangle so this is a reduction.
The scale factor cannot be bigger than 1 because the image shrunk so D is definitely not a possibility.
E. is a possibility but let's actually find the scale factor to see.
We can calculate or or to find out what the scale factor is.
.
The scale factor is 2/5.
Answer: 18
Step-by-step explanation: The formula for calculating a triangle’s area is 1/2(base•height). This means that 12•3 is 36, which multiplied by 1/2 is 18.
(Hope this helps)
Using the chain rule.
<span><span>sin^3</span>(x) = [sin(x)<span>]^3
</span></span><span><span>d/<span>dx</span></span>[sin(x)<span>]^3</span>∗<span>d/<span>dx</span></span>[sin(x)]
</span>d/dx sinx = cosx
d/dx<span> cosx = -sinx </span>
d/dx<span> (-sinx) = -cosx </span>
d/dx <span>(-cosx) = sinx
back to where we started from!!! </span>
So,
repeat repeat repeat !!
