given the vector with a manitude of 9m at an angle a of -80 degrees, decompose this vector into two vector components oarallel t
lana [24]

Answer:

We have the magnitude, M, and the angle A.

(The angle is always measured from the +x-axis)

Then we have that:

x = M*cos(A)

y = M*sin(A)

in this case:

M = 9m

A = -80°

x = 9m*cos(-80°) = 1.562

y = 9m*sin(-80) = -8.86m

Now, the component parallel to the x axis is:

x = 9m*cos(-80°) = 1.562 m

And the slope of something parallel to the x-axis is always zero, as this is a constant line.

Factor 75t2 + 12.<br> 3(5t + 2)2<br> 3(25+2 +4)<br> 3(251-4)
frosja888 [35]

Answer:

75t^2+12=3(25t^2+4)

Option C)

Step-by-step explanation:

Here we are given with the expression 75t^2+12

The GCF of 75t^2 and 12 is 3

Hence we take 3 as GCF and bring it in front of the bracket.

3(25t^2+4)

It can not be factorise furthure  as there is no GCF of 25 and  also there is no rule for sum of squares so that we may apply it on this. Hence the answer would be

3(25t^2+4)

Option C)
