Answer:
step 1 was wrong she should have added 25 to both sides
Step-by-step explanation:
step 3 was correct she divided both sides by -5
Percy earns a greater hourly wage of $7.50 at the library.
The correct question is;
A particle is moving along the curve
y=√x. As the particle passes through the point (4, 2), its x-coordinate increases at a rate of 4 cm/s. How fast is the distance from the particle to the origin changing at this instant? (Round your answer to three decimal places.)
Answer:
dS/dt ≈ 4.025 cm/s
Step-by-step explanation:
Let the distance from the origin be S and thus, the formula for that is
S = √x² + y²
The given function is y =√x
Let's plug in the S function for y to get;
S = √x² + (√x)²
S = √(x² + x)
Now, let's find the derivative with respect to time;
So;
dS/dt= [(1/2)/√(x² + x)] (2x+1)dx/dt
Let's plug in the value of x = 4 and dX/dt as 4;
dS/dt= [[(1/2)/√(4² + 4)] x [((2(4)+1)]] x 4
dS/dt= [(36/4)/√5]
dS/dt = 9/√5
dS/dt = 4.025 cm/s
Answer:
<C = 62 degrees, <B= 118 degrees
Step-by-step explanation:
Opposite angles of parallelograms are always congruent.
Consecutive ( angles that are next to each other ) always add up to 180.
180-62=118
