WHAT IS THE SLOPE IF I HAVE (-3,5) AND (4,-5)

irina [24]

Answer:

-10/7

Step-by-step explanation:

Use slope formula

$\frac{y2-y1} {x2-x1}$

x1= -3

y1 = 5

x2 = 4

y2 = -5

$\frac{-5-5}{4--3}$

<h2> $\frac{-5 + -5}{4 +3}$ </h2>

$\frac{-10}{7}$

Guyss please help me with this question. I tried a thousand times but it's still incorrect.

Answer: $17.68cm$

Step-by-step explanation:

Using the area formula of a cone, find the height first.

$A=\pi r(r+\sqrt{h^2+r^2})$

Solve for h,

Begin by dividing by $\pi r$

$\frac{A}{\pi r}=r+\sqrt{h^2+r^2}$

Subtract r.

$\frac{A}{\pi r}-r=\sqrt{h^2+r^2}$

Square both sides.

$(\frac{A}{\pi r}-r)^2=(\sqrt{h^2+r^2})^2$

$(\frac{A}{\pi r}-r)^2=h^2+r^2$

Subtract $r^2$

$(\frac{A}{\pi r}-r)^2-r^2=h^2$

Extract the square root.

$\sqrt{(\frac{A}{\pi r}-r)^2-r^2 } =\sqrt{h^2}$

$\sqrt{(\frac{A}{\pi r}-r)^2-r^2 } =h$

Plug in your values.

$\sqrt{[\frac{670cm^2}{(3.14)(8cm)}-(8cm)]^2-(8cm)^2 } =h$

Solve;

$\sqrt{[\frac{670cm^2}{25.12cm}-(8cm)]^2-(8cm)^2 } =h$

$\sqrt{[26.67cm-(8cm)]^2-(8cm)^2 } =h$

$\sqrt{(18.67cm)^2-(8cm)^2 } =h$

$\sqrt{348.57cm^2-64cm^2}=h$

$\sqrt{284.57cm^2}=h$

$15.77cm=h$

------------------------------------------------------------------

Now, to find the slant height use this formula: $l=\sqrt{h^2+r^2}$

$l=\sqrt{(15.77cm)^2+(8cm)^2}\\l=\sqrt{248.69cm^2+64cm^2}\\ l=\sqrt{312.69cm^2}\\ l=17.68cm$

In the expression 15- the sum of 6 and. 7 do you add or subtract first

denpristay [2]

Answer:

Add

Step-by-step explanation:

By the way this question was worded, I'm going to say add. If I were to write the expression out, I personally would write it like this:

$15-(6+7)$

And parentheses always occur first.

Hope this helps!
