Step-by-step explanation:

6. angle 1 = angle 4 = 60deg (vertically opposite angles)

7. angle 3 = 180 - 40 - 60 = 80deg (angles on a straight line are supplementary)

8. angle 5 = angle 2 = 40deg (vertically opposite angles)

9. angle 6 = angle 3 = 80deg (vertically opposite angles)

10. angle 7 = angle 5 + angle 4 = 40 + 60 = 100deg (alternate angles, //lines)

11. angle 8 = 180 - 100 = 80deg (angles on a str line are supplementary)

12. angle 9 = 180 - 80 - 40 = 60deg (angles in a triangle)

13. angle 10 = 180 - 60 = 120deg (angles on a str line are supplementary)

14. angle 11 = angle 9 = 60deg (vertically opp angles)

15. angle 12 = angle 10 = 120deg (vertically opp angles)

Im confused..I feel as if what I’m learning in class itself is not as difficult as the problems my teacher gives us to take home

RideAnS [48]

Ok, so remember that the derivitive of the position function is the velocty function and the derivitive of the velocity function is the accceleration function

x(t) is the positon function
so just take the derivitive of 3t/π +cos(t) twice
first derivitive is 3/π-sin(t)
2nd derivitive is -cos(t)
a(t)=-cos(t)

on the interval [π/2,5π/2) where does -cos(t)=1? or where does cos(t)=-1?
at t=π
so now plug that in for t in the position function to find the position at time t=π
x(π)=3(π)/π+cos(π)
x(π)=3-1
x(π)=2
so the position is 2

ok, that graph is the first derivitive of f(x)
the function f(x) is increaseing when the slope is positive
it is concave up when the 2nd derivitive of f(x) is positive

we are given f'(x), the derivitive of f(x)
we want to find where it is increasing AND where it is concave down

it is increasing when the derivitive is positive, so just find where the graph is positive (that's about from -2 to 4)

it is concave down when the second derivitive (aka derivitive of the first derivitive aka slope of the first derivitive) is negative
where is the slope negative?
from about x=0 to x=2
and that's in our range of being increasing
so the interval is (0,2)

Evaluate the following using<br> powers of ten rules.<br> 104)1.042

Alinara [238K]

Answer:

0.0001042

Step-by-step explanation:

Power of tens rule states that if the denominator of a fraction has the positive power of 10, decimal in the numerator will be shifted to the left by the same number of places as exponent.

10⁴) 1.042 = $\frac{1.042}{10^4}$

In the denominator of the given fraction, exponent of 10 = +4

So the decimal in numerator will be shifted left by 4 places.

$\frac{1.042}{10^4}=0.0001042$

Therefore, answer is 0.0001042
