Answer:

-4, 14+(-5) (-0.8), 14+ (3) (-0.8), 16.4

Step-by-step explanation:

The change in temperature for -5 is -4

The expression for -5 is 14+ (-5) (-0.8)

The expression for 3 is 14+ (3) (-0.8)

The actual temperature for 3 is 16.4

I did the math.

Answer:

Slope = y^2 - y^1 / x^2 - x^1

Graph n1

Slope = -5 - 1 / -6 - 2

Graph n2

Slope = -5 - 3 / 3 - 5

Graph n3

Slope = 3 - 0 / -4 - 5

Suppose the radius of a circle is 8. What is its area?

monitta

The Formula to find the Area of a circle using the radius is:
$A = \pi r^2$

r = 8
So:
$A = \pi r^2$
$A = \pi 8^2$
$A = \pi64$

And you get about 201.06193

So, the area of a circle with a radius of 8 is about 201.06

Hope this Helps :)

Answer:

$x1=\frac{-2-2\sqrt{29401} }{245} x2=\frac{-2+2\sqrt{29401} }{245}$

Step-by-step explanation:

Step One: Convert

49/16x^2-2=-0.05x+4

Step Two: Multiply Both Sides by 80

245x^2-160=-4x+320

Step Three: Move everything to the left

245x^2+4x-480=0

Final Step: Quadratic Formula

$x1=\frac{-2-2\sqrt{29401} }{245} x2=\frac{-2+2\sqrt{29401} }{245}$

If you know the area and the base of a triangle, how can you find the height?

Y_Kistochka [10]

Answer: do your values into the equation A=1/2bh and do the math. First multiply the base (b) by 1/2, then divide the area (A) by the product. The resulting value will be the height of your triangle!
