Find the value of p for which 81p ÷ 9p = 94 ?

Radda [10]

Answer:

p = 10.44

Step-by-step explanation:

There is no solution. If the question was 81p / 9 = 94, it could be done.

The way it is written the ps cancel out and you get 9 = 94 which is impossible.

But let's assume you meant

81p / 9 = 94

Then you get 9p = 94 Divide both sides by 9

81p/9 = 94

9p = 94 Divide both sides by 9

9p/9 = 94/9

p = 10.44

PLEASE HELP AND ANSWER!!!!! Which of the following reveals the minimum value for the equation 2x2 + 12x − 14 = 0?

NARA [144]

Answer:

The correct option is 3.

Step-by-step explanation:

The given equation is

$2x^2+12x-14=0$

It can be written as

$(2x^2+12x)-14=0$

Taking out the common factor form the parenthesis.

$2(x^2+6x)-14=0$

If an expression is defined as $x^2+bx$ then we add $(\frac{b}{2})^2$ to make it perfect square.

In the above equation b=6.

Add and subtract 3^2 in the parenthesis.

$2(x^2+6x+3^2-3^2)-14=0$

$2(x^2+6x+3^2)-2(3^2)-14=0$

$2(x+3)^2-18-14=0$

$2(x+3)^2-32=0$ .... (1)

Add 32 on both sides.

$2(x+3)^2=32$

The vertex from of a parabola is

$p(x)=a(x-h)^2+k$ .... (2)

If a>0, then k is minimum value at x=h.

From (1) and (2) in is clear that a=2, h=-3 and k=-32. It means the minimum value is -32 at x=-3.

The equation $2(x+3)^2=32$ reveals the minimum value for the given equation.

Therefore the correct option is 3.

The coordinates of point S are (8.4). What are the

Lerok [7]

Answer:

Co-ordinates of point R is (26,2)

Step-by-step explanation:

Given point:

Endpoint S(8,4)

Mid-point M of segment RS (17,3)

Let endpoint $R$ have co-ordinates $(x_2,y_2)$

Using midpoint formula:

$M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

Where $(x_1,y_1)$ and $(x_2,y_2)$ are co-ordinates of the endpoint of the segment.

Plugging in values to find the midpoint of segment KN.

$M=(\frac{8+x_2}{2},\frac{4+y_2}{2})$

We know $M(17,3)$

So, we have

$(17,3)=(\frac{8+x_2}{2},\frac{4+y_2}{2})$

Solving for $x_2$

$\frac{8+x_2}{2}=17$

Multiplying both sides by 2.

$\frac{8+x_2}{2}\times 2=17\times 2$

$8+x_2=34$

Subtracting both sides by 8.

$8+x_2-8=34-8$

∴ $x_2=26$

Solving for $y_2$

$\frac{4+y_2}{2}=3$

Multiplying both sides by 2.

$\frac{4+y_2}{2}\times 2=3\times 2$

$4+y_2=6$

Subtracting both sides by 4.

$4+y_2-4=6-4$

∴ $y_2=2$

Thus co-ordinates of point R is (26,2) (Answer)
