Answer:
v(t) = 6t^2 +5
Step-by-step explanation:
Velocity is the derivative of position. The derivative of a sum is the sum of the derivatives of its terms. The power rule for derivatives is ...
(d/dx)(x^n) = n·x^(n-1)
So, the derivative of d(t) is ...
v(t) = 2(3t^2) +5(1t^0)
v(t) = 6t^2 +5 . . . . matches choice C
2.04*10^6
When in scientific notation, there can only be one whole integer. For example, we could not have done 20.4*10^5.
Since there were 6 zeroes after the decimal point, the exponent of 10 is 6.
Hope this helps!

3 exponent 3 = 27.
27 + 12 = 39
<u>☁️</u><u>My Answer☁️:</u>
y = 90°
<u>✧My Step-by-step explanation✧:</u>
The angle x forms a straight line with the both the 50° angle and the 40° angle:
x + 50° + 40° = 180°
x = 90°
Which means…
y = x = 90°
You would do 3x+90=180 because a straight line equals 180°. then you find x=30. then x and z add to get 180 because x fits in the slot above z so 180-30 equals 150°. if z equals 150° then 180-150 equals 30. so x=30,y=15, and z=150
