A city planner wants to build a road perpendicular to D Street. What is the slope of the new road?

Romashka-Z-Leto [24]

Answer:

The slope of the new road is 0.

Step-by-step explanation:

the slope of d street line is tan(90)

[if the angle made by a line with x axis is $\alpha$ then, the slope of that line will be tan( $\alpha$ ) ]

here, the angle made by the d street line with x axis is 90 degrees.

if a road is to be built which is perpendicular to d street , it should make 0 degrees i.e, it should be parallel to x axis .

so, the slope of new road will be tan(0) = 0

Let g(x) = 2x2 - 11x. Find g(-1). A) -13 Eliminate B) -9 C) 0 D) 13

worty [1.4K]

Solution

g(x) = 2 $x^{2}$ - 11x

Plugging in x = -1 in g(x), we get

g(-1) = 2 $(-1)^{2}$ - 11(-1)

Now we have to simplify it.

g(-1) = 2*1 + 11

g(-1) = 2 + 11

g(-1) = 13

So the answer is D) 13.

Thank you. :)
