Answer: The slope of the other line is 7/5


Step-by-step explanation:

When looking for the slope of two perpendicular lines, the slope of the unknown is going to be the opposite reciprocal of the known line.


So here's another example. There's two perpendicular lines. The known is 2x. That means the unknown is going to be -1/2.

The known is -4/7. The unknown is 7/4.

Hope I could help! :)

HELP ME PLEASE!!<br> is y=2x^2 - 4 linear or non linear
OleMash [197]

Answer:

non-linear

Step-by-step explanation:

Linear functions can only have powers of 1 for the x and y terms and the terms must not be multiplied.

The function y =2x^2-4  has a power of 2 on the x so it is not linear.  It is parabolic.

Dang it these are tricky for me can somebody help?
erica [24]

Answer:

It has no perfect square factors, unless you count 1 = 1^2. That's sort of a degenerate case we don't usually count, since every integer has that factor. We would usually say that 1290 is a square-free integer. Hope this helps!!

What is the vertical height, h?
bixtya [17]

Answer:

<h2>             6.2</h2>

Step-by-step explanation:

s = 10 so ¹/₂s = 5

Pythagorean theorem:

h^2+(\frac12s)^2=8^2\\\\h^2+5^2=8^2\\\\h^2=64-25\\\\h^2=39\\\\h=\sqrt{39}=6.2449979....\approx6.2

Which set of ordered pairs does not represent a function
Alex Ar [27]
<h3>Answer:</h3>

The Second one {(-8,-7), (4,-2), (2,9), (-8,8)}

<h3 /><h3>Step-by-step explanation:</h3>

A function only gives ONE out put for a given value. But the second set has two outputs if we input -8, it gives you -7 and 8 so this must not be a function.

Un jardín rectangular de 50 cm de largo por 34 m de ancho está rodeado por un camino de arena uniforme.Halla la anchura de dicho
Anastasy [175]

Answer:

5.85 m

Step-by-step explanation:

The width of the sand road can be calculated knowing its area and the dimensions of the rectangular garden as follows:

A_{g} = a.b

<u>Where:</u>

Ag: is the area of the rectangular garden

a: is the length of the rectangular garden = 50 cm = 0.5 m

b: is the width of the rectangular garden = 34 m

A_{s} = 540 m^{2}

<u>Where</u>:

As: is the area of the sand road

The relation between the area of the sand road and the area of the rectangular garden is the following:

A_{s} + A_{g} = (a+2x)*(b+2x)

540 m^{2} + 0.5m*34m = ab + 2ax + 2bx + 4x^{2}

557 m^{2} = ab + 2x(a + b) + 4x^{2}

557 m^{2} - 17m^{2} - 2x(34.5 m) - 4x^{2} = 0

540 - 69x - 4x^{2} = 0                              

By solving the above equation for x we have two solutions:

x₁ = -23.10 m

x₂ = 5.85 m

Taking the positive value, we have that the width of the sand road is 5.85 m.

I hope it helps you!
