Answer:
a.<55, -27>
Step-by-step explanation:
The given vectors are u = <7, -3>, v = <-9, 5>.
We want to find 4u - 3v.
We substitute the vectors and multiply by the scalars.
4u - 3v=4<7, -3>-3 <-9, 5>.
4u - 3v=<28, -12>- <-27, 15>.
4u - 3v=<28--27, -12-15>
4u - 3v=<55, -27>
Answer: There can be 2 gold 1 silver, 2 silver one gold, 3 silver, or 3 gold.
I'm not really sure if this is correct but I hope this helps:)
743.476 < 743.746
743.746 > 743.476
What are the directions for this?
Answer:
r ≈ 2.39 inches.
Step-by-step explanation:
I think your question is missed of key information of the height, allow me to add in and hope it will fit the original one.
<em>The cylinder shown has a lateral surface area of about 750 square inches. Which answer is closest to the measure of the cylinder's radius? Use 3.14 to approximate pi. the height being 50 inches.</em>
My answer:
Given that the lateral surface area of about 750 square inches and its height is 50 inches.
We have the formula ti find the surface area of the cylinder is:
S = h(2πr)
<=> 750 = 50*2*3.14*r
<=> r ≈ 2.39 inches.
Hope it will find you well.
