Answer:

NOT a function
domain: [-2, 2]
range: [-4, 4]

Step-by-step explanation:

A vertical line intersects the graph twice, so the relation is not a function. It is only allowed to intersect once if the relation is a function.

The domain is the horizontal extent, which is from -2 to +2.

The range is the vertical extent, which is -4 to +4.

Answer:

$c = 16.392\,\frac{USD}{ft^{2}}$

Step-by-step explanation:

The surface area of the cone shaped roof is:

$A_{s} = \pi\cdot (10\,ft)\cdot (6\,ft)$

$A_{s} \approx 188.496\,ft^{2}$

The cost of roofing per square feet is: (USD stands for US dollar)

$c = \frac{3089.76\,USD}{188.496\,ft^{2}}$

$c = 16.392\,\frac{USD}{ft^{2}}$

Solve for me pls :)

I am Lyosha [343]

Answer:

Step-by-step explanation:

$f(x) = \frac{3}{x + 2} - \sqrt{x - 3} \\$

To find f(19) , substitute the value of x that's 19 into f(x). That is for every x in f (x) replace it with 19

We have

$f(19) = \frac{3}{19 + 2} - \sqrt{19 - 3} \\ = \frac{3}{21} - \sqrt{16} \\ = \frac{1}{7} - 4 = \frac{1 - 28}{7}$

We have the final answer as

$f(19) = - \frac{27}{7} \\$

Answer:

Option 4

Step-by-step explanation:

Term = n/(4^n)

(n+1)th term = (n+1)/[4^(n+1)]

Ratio: (n+1)/[4^(n+1)] ÷ n/(4^n)

= (n+1)/[4^(n+1)] × (4^n)/n

= [(n+1)/n] × (1/4)

For large n, (n+1)/n approaches 1

[(n+1)/n] × (1/4) approaches 1/4 which is less than 1

Since the ratio is less than 1, series converges
