y=8√3

Step-by-step explanation:

y = cos 60° ×16 = ½× 16 = 8

x = sin 60° ×16 = ½√3 × 16 = 8√3

What would be the vertex of X+6=0??

natita [175]

Answer:

Any point on the line.

Step-by-step explanation:

x+6=0 is a straight line, and this line is infinite. You can pick three points on the line and the middle point is the vertex. This vertex can be any point on the line because there are an infinite amount of points to choose.

URGENT!

stepladder [879]

Answer:

Rate = 13.173% per year

Step-by-step explanation:

**Not 100% sure about this answer, but I think it's right.**

Calculation Steps:

Solving for rate r as a decimal

r = n[(A/P)^1/^nt - 1]

r = 1 × [(668.00/359.80)^1/^(1)^(5) - 1]

r = 0.131731

Then convert r to R as a percentage

R = r * 100

R = 0.131731 * 100

R = 13.173%/year

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,∞)
