Answer:
Correct arrangement of equation of displacement to find a is as follows;
1- Vt - d = 1/2 a t^2 (^ represents exponent i.e. t square as given in equation)
2- 2(Vt - d ) = a t^2
3- a = 2(Vt - d )/ t^2 (keep in mind, 2(Vt - d) whole divided by t^2)
Step-by-step explanation:
1- In the first equation, Vt is taken to the left side of the equation (keep in mind, original equation of displacement used for reference as given in question) and multiplied by -1 on the both sides of the equation.
2- In the second equation, 2 is multiplied on the both sides.
3- Multiply t^2 on both sides of the equation, We will get a in correct arrangement, which is required to find.
The given statement 5x=4y=12 and x+6y=5 is true.
<u>Step-by-step explanation:</u>
The question comes from linear equations in two variables.
Here, two unknown variables represent a certain situation and their value can be obtained by solving both the given equations.
The cost of cookie is represented by the variable x and cost of doughnuts can be represented by the variable y.
The coefficient of each variable in the equation represent the quantity or the number of units of each baked good.
On comparing the given equations from the data provided in the question, the statement can be stated as true.
Supplementary and adjacent are the two correct choices.
23 is your answer. IT's 22.8 but rounded up its 23
Answer:
- 3108
Step-by-step explanation:
The sum to n terms of an arithmetic series is
= [ 2 + (n - 1)d ]
Substitute the given values into the formula
= [ (2 × - 26) + (23 × - 9) ]
= 12 ( - 52 - 207 )
= 12 × - 259 = - 3108
