3 is an element in the domain of the function g(x)= -2x - 4 . What is the corresponding element in the range?

Bess [88]

Hello! :)

$\large\boxed{g(3) = -10}$

If 3 is apart of the domain, then x = 3.

The range is equivalent to g(x), or the y-value. To solve for this when x = 3, we must plug 3 into the equation:

g(x) = -2x - 4

g(3) = -2(3) - 4

Simplify:

g(3) = -6 - 4

g(3) = -10

Find the area of a regular hexagon with a base of 15 and an apothem of 20.

seraphim [82]

Area of hexagon = base * (apothem/2) * 6 = 3(base*apothem)
=3*15*20
=900 square units.

However, a hexagon consists of 6 equilateral triangles in which the apothem is 0.866 times the base, meaning that the apothem is shorter than the base.
Perhaps the base is 20 and apothem 15. The answer will come to be the same though.

. Find sets of parametric equations and symmetric equations of the line through the point parallel to the given vector or line (

omeli [17]

Answer:

a) L(x,y,z) = (-4,0,2)+(2,8,-7)*t

b) (2-z)/7= y/8=(x+4)/2 (option B)

Step-by-step explanation:

the parametric equation of the line passing through the point P₀= (-4,0,2) and parallel to the vector v=2i + 8j - 7k is

L(x,y,z)=P₀+v*t

therefore

L(x,y,z) = (-4,0,2)+(2,8,-7)*t

x=x₀+vx*t = -4 + 2*t

y=y₀+vy*t = 8*t

z=z₀+vz*t = 2 -7*t

solving for t in the 3 equations we get the symmetric equation of the line:

(2-z)/7= y/8=(x+4)/2

thus the option B is correct

My sister needs some help with her homework. Can someone lend her a hand?

Neporo4naja [7]

Answer:

600 = 10 x 60

Step-by-step explanation:

If you do 10 x 60 or 60 x 10 it'll equal 600, that's what the questons is looking for so the way it'd be written is:

6 hundreds is 10 times as much as 600.

600 = 10 x 60

Hopefully this helps! I hope you and your sister have a blessed day!
