Answer:
-4m/s²
Step-by-step explanation:
<u>Given</u><u> </u><u>Equation</u><u> of</u><u> </u><u>velocity</u><u> </u><u>:</u><u>-</u><u> </u>
<u>Differenciation</u><u> </u><u>of </u><u>first </u><u>order</u><u> </u><u>will </u><u>give </u><u>acclⁿ</u><u> </u><u>:</u><u>-</u><u> </u>
- v = 6t² - 4t -2
- dv/dt = d(6t² - 4t -2)/dt
- dv/dt = 2*6 t¹ - 4*1 t⁰ - 0
- dv/dt = 12t - 4
- a = 12t - 4
<u>At </u><u>t </u><u>=</u><u> </u><u>0</u><u> </u><u>,</u>
- a = 12*0 - 4 m/s²
- a = -4m/s²

Answer:
Step-by-step explanation:
Congruent sides are the same length.
AB = DF
3(2x +10) = 12x +12
6x +30 = 12x +12 . . . . eliminate parentheses
18 = 6x . . . . . . . . . . . . subtract 6x+12
3 = x . . . . . . . . . . . . . divide by 6

BC = FG
2y +12 = 2(2y -3)
y +6 = 2y -3 . . . . . . . divide by 2
9 = y . . . . . . . . . . . . subtract y-3
Answer:
There are 604,800 possible permutations.
Step-by-step explanation:
The order in which the digits are chosen is important, which means that the permutations formula is used to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
In this question:
7 digits from a set of 10(10 digits to 0-9). So
There are 604,800 possible permutations.

Answer: Same <u>value</u> but look <u>different</u>
Step-by-step explanation:
3/4 x 2/2 = 6/8
2/3 x 4/4 = 8/12
both of 6/8 is equivalent to 3/4
8/12 is equivalent to 2/3
