Answer: 299 m/s
Step-by-step explanation:
The first step is to take the first derivative of the equation given. This will give us the equation for velocity which we will then substitute the 7 in for t.
To derive the equation you multiply the coefficient by the power of the variable, then subtract one from the variable.
v(t) = 6t^2 + 5
Now input 7 in for t to find the velocity.
v(7) = 6(7)^2 + 5
v(7) = 299 m/s
Answer:
Solution given:
9x-2y=7
making it in a form of y=mx+c
9x-7=2y
y=9/2x -7/2
Comparing above equation with y=mx+c
we get
m=9/2
Since it is passes parallel to (5,-3)
slope will be same
now
Equation of line
y-y1=m(x-x1)
y+3=9/2(x-5)
y=9/2x-5/2-3
<u>y=9/2 x-11/2 is a required equation.</u>
Answer:
The graph is shown below.
D. Infinite solutions; these are equivalent equations.
Step-by-step explanation:
Given:
The pair of linear equations are:
Multiply equation (1) by -2. This gives,
Now, equations (2) and (3) are same and hence the equations (1) and (2) are the equations of the same line.
In other words, the two lines overlap each other completely. Hence, all the points on the line are the solutions of the given pair of lines. We know that, there are infinitely many points on a line. So, there are infinitely many solutions
The graph is plotted below to support the same.
Therefore, the correct option is option D: Infinite solutions; these are equivalent equations.
