We know

$\boxed{\sf tan\Theta=\dfrac{Perpendicular}{Base}}$

Now

$\\ \sf\longmapsto tanW=\dfrac{XY}{XZ}$

$\\ \sf\longmapsto tanW=\dfrac{12}{5}$

$\\ \sf\longmapsto tanW=2.4$

A parabola has zeros at (5,0) and (-3,0) and passes through point (6,18) determine the axis of symmetry

worty [1.4K]

Answer:

The axis of symmetry is $x=1$

Step-by-step explanation:

we know that

In a vertical parabola, the axis of symmetry is equal to the x-coordinate of the vertex

In this problem we have a vertical parabola open upward

The x-coordinate of the vertex is equal to the midpoint between the zeros of the parabola

$x=\frac{5-3}{2}=1$

therefore

The axis of symmetry is $x=1$

PLEASE HELP ITS DUE TODAY!!! Write an equation in which the quadratic expression 2x^2-2x 12 equals 0. Show the expression in fac

stepladder [879]

This is the function

${2x}^{2} - 2 {x}^{1} + 12$

Then factor 2 out

$2(x^2- x + 6) = 0$

Divide both side by two and use the quadratic formula to get the following

$(x - 3)(x + 2) = 0$

X=3 And x=-2 and don't forget to Chek them

Can y'all please help.

Answer:

See explanation

Step-by-step explanation:

<u>Step 1.</u> Substitute for d to solve for n:

From the first equation:

$d=70-n$

Then substitute it into the second equation:

$0.1(70-n)+0.05n=5.5\\ \\7-0.1n+0.05n=5.5\\ \\7+(-0.05n)=5.5\\ \\-0.05n=5.5-7=-1.5\\ \\n=\dfrac{-1.5}{-0.05}=30$

<u>Step 2:</u> Substitute for n to solve for d:

$d+n=70\\ \\d+30=70\\ \\d=70-30=40$
