Answer:

to find the intersection we substitute the formulas for x, y and z into the equation for P and solve for t. The line is contained in the plane, i.e., all points of the line are in its intersection with the plane. Here are cartoon sketches of each part of this problem.

Answer:

Domain [-5,∞)

Range [0,∞)

Step-by-step explanation:

Part 1) Find the domain

we have

$f(x)=\frac{1}{2}\sqrt{x+5}$

we know that

The radicand must be greater than or equal to zero

$x+5\geq 0$

solve for x

subtract 5 both sides

$x\geq -5$

The solution for x is the interval [-5,∞)

All real numbers greater than or equal to -5

Remember that

The domain of a function is the set of all possible values of x

therefore

The domain of the function f(x) is the interval [-5,∞)

Part 2) Find the range

we have

$f(x)=\frac{1}{2}\sqrt{x+5}$

Find the value of f(x) for the minimum value of x

For x=-5

$f(x)=\frac{1}{2}\sqrt{-5+5}$

$f(x)=0$

The minimum value of f(x) is equal to zero

The solution for f(x) is the interval [0,∞)

All real numbers greater than or equal to 0

Remember that

The range of a function is the complete set of all possible resulting values of y, after we have substituted the domain.

therefore

The range of the function is the interval [0,∞)

Answer:

They made 4 forks and 6 spoons last April.

Step-by-step explanation:

Let forks they made in april be x and spoons be y.

To make 1 fork we need $2

To make 1 spoon we need $1

They sell 1 fork for $6 and 1 spoon for the same amount So,

now,

Turning it into two equations :-

(x = number of forks and y = number of spoons)

2x + 1y = 14

6x + 6y = 60

Now,

2x + y = 14

y = 14 - 2x

Now,

6x + 6y = 60

or, 6x + 6(14-2x) = 60

or, 6x + 84 - 12x = 60

or, -6x = -24

so, x = 4

Now,

y = 14 - 2x

or, y = 14 - 2×4

or, y = 14-8

so, y = 6
