Answer:
The horizontal component of force is 1.99 pounds.
Step-by-step explanation:
We are given the following in the question:
Force = 2.8 Newtons.
The attached image shows the arrangement.
Angle made by the water stream with the ground
The horizontal component is given by:
Thus, the horizontal component of force is 1.99 pounds.
Let denote the amounts (in liters) of the 20%, 30%, and 60% solutions used in the mixture, respectively.
The chemist wants to end up with 72 L of solution, so
while using twice as much of the 60% solution as the 30% solution, so
The mixture needs to have a concentration of 35%, so that it contains 0.35•75 = 26.25 L of pure acid. For each liter of acid solution with concentration , there is a contribution of liters of pure acid. This means
Substitute into the total volume and acid volume equations.
Solve for and . Multiply both sides of the second equation by 5 to get
By elimination,
so that
and
Answer:
f^-1(4) = 2
f^-1(-5) = -4
f^-1(0) = 0
Step-by-step explanation:
To find the inverse of the function, we simply switch the places of x and y
You simply find the value given on the y-axis and trace to the x-axis
Thus, we have the following ;
f^-1(4) = 2
f^-1(-5) = -4
f^-1(0) = 0
Answer:
d - 9 < -7
Step-by-step explanation:
Plug in -15 for d. So -15 - 9 which give you -24. -24 is less than -7
