Answer:
3.45
Step-by-step explanation:
24.84/7.2 = 3.45
As it is given here
initial speed is
v_i = 6 m/s
After 4 seconds the final speed is
v_f = 14 m/s
so here we can use the formula of acceleration using kinematics
a = \frac{v_f - v_i}{t}
a = \frac{14 - 6}{4}
a = 2 m/s^2
so here it will accelerate at 2 m/s^2 rate.
Answer:
Step-by-step explanation:
We are given two fractions and are asked to simplify it.
So
We can follow the exponent rule of subtracting them since both fractions are the same value.
Now do the negative exponent rule :
Move the negative in between the fraction :
And apply the fraction switcharoo :
Answer:
Step-by-step explanation:
tan Ф = opposite side divided by the adjacent side
tan Ф = opp/adj in your problem Ф is x
tan x = 4/9
x = arctan (4/9) on your calculator arctan is might look like inverse tan
or you might have to use the 2nd (second) button and then tan
x = inverse tan (0.44444 repeating) try it on your own calculator
= 23.962488974578183 rounds up to 24.0
= 24.0
