F(x)=-x^2-5 find the range

lina2011 [118]

$x = \frac{ - b}{2a} \\ = \frac{0}{2(1)} = 0 \\ f(0) = (0)^{2} - 5 \\ = 0 - 5 = - 5$
The vertex is at (0,-5), therefore the range goes from (-infinity, - 5]

Max's car holds 18 gallons of gasoline. Driving on the highway, the car uses approximately 2 gallons per hour. Let h represent t

Mice21 [21]

Y= 18 gallons-2(h)
y is what you're trying to find out and since there are 18 gallons in the tank after every hour you would have 2 less gallons. So, you can multiply how many hours he's been driving by the 2 gallons and subtract it from 18

20 POINTS, please help!!Factor the algebraic expression below in terms of a single trigonometric function.

Lubov Fominskaja [6]

Csc²x - 1

1/sin²x - 1

1/sin²x - sin²x / sin²x

(1 - sin²x) / sin²x

Recall that sin²x + cos²x = 1

So cos²x = 1 - sin²x

So we can replace numerator to cos²x

cos²x / sin²x

= cot²x

Final answer: cot²x

3 more than a number then divided the result by 8

ziro4ka [17]

We are given statement : 3 more than a number then divided the result by 8.

We need to write an algebraic expression for it.

Let us assume unknown number be n.

3 more than n = (n+3).

Now, we need to divide that result (n+3) by 8.

So, we would get (n+3) divided by 8 = $\frac{n+3}{8}$ .
