at is another way to write the expression ​ p⋅(10−2) ​ ? (10⋅2)−p 10⋅2−p (10⋅2)⋅p (p⋅10)−(p⋅2)
Ostrovityanka [42]

Answer:

(p ⋅ 10) − (p ⋅ 2)

Step-by-step explanation:

Try to substitute "p" with any number.

Let's say p = 2

So

p ⋅ (10 − 2)

2 ⋅ (10 − 2)

2 ⋅ (8)

= 16

Now for the other equations

(p ⋅ 10) − (p ⋅ 2)

(2 ⋅ 10) − (2 ⋅ 2)

(20) - (4)

= 16

(10 ⋅ 2) − p

(10 ⋅ 2) − 2

(20 ) − 2

= 18

10 ⋅ 2 − p

10 ⋅ 2 − 2

20 - 2

= 18

(10 ⋅ 2) ⋅ p

(10 ⋅ 2) ⋅ 2

(20) ⋅ 2

= 40

Only (p ⋅ 10) − (p ⋅ 2) has the same result as p ⋅ (10 − 2).

Cheers

What is the equation of the directrix of the parabola given by the equation y2 = -24x?
tino4ka555 [31]
Since y is the suqraed term, it opens left or right
in this form it is
(y-k)²=4p(x-h)

(h,k) is the vertex
if p is negative then it opens to the left and directix is to the right of the vertex
if p is positve then it opens to the right and directix is to the left of the vertex
p is the distance from vertex to directix


so
(y-0)²=4(-6)(x-0)
the vertex is (0,0)
-6 is negative
so
vertex is (0,0)
directix is 6 unts to the right of (0,0) or at x=6

the directix is x=6

Wouldnt it be 15??? I would guess so. Katie keeps deleting this but Im not sure why. Sorry katie but I really need help
Anna007 [38]

Answer:

25 in; C

Step-by-step explanation:

Hey!

There probably is a reason she is deleting. You could contact her or ask some help elsewhere.

Anyway! I'm trying to get this in fast. (Remember the Pythagorean Theorem?) That will be very useful here since it is a right triangle.

<u>L² + L² = H² (or H² - L² = L²):</u>

In that case, we'll use the second one because our Hypotenuse is given.

We can substitute each value of the numbers:

65² - 60² = L²

Evaluating:

4225 - 3600 = 625

√625 = 25 inches

Thusly, the third side would be \boxed{25{\text{\:inches\:or\:C.}}}

<em>Also note we could have simplified into a Pythagorean Triple. This method is a simpler more basic method for learning the concept.</em>

Hope this helps!

Jordan prepares 200 name tags to use at a meeting. The number for each color of the name tag is described below.
nadya68 [22]

Answer:

The answer would be A. 55.

Step-by-step explanation:

For the 35% you would take your 200 and divide it by 2 and have two 100's. Since 35% is out of 100% you could take 35 from each 100 and add them together to get 70.

For the 3/8 you would divide and get .375 then you would multiply that by 200 which would give you 75 yellow tags. Then you would add 75 and 70 and get 145. Then subtract 145 from 200 to get 55. Therefore there would be 55 red tags.
