(1/8)^(x+2)=16^(2-x)

mixas84 [53]

1/8*2x=16*2x
devide 2x from both sides 1/8=16(x)
1/8=16x divide 16 from both sides
which is x=0.008

System of conics help

ZanzabumX [31]

Answer:

Solutions are (6,3) and (-2,3).

Step-by-step explanation:

From the first equation given we can write:

$(x-2)^{2} = 16-(y-3)^{2}\\$

substituting for $(x-2)^{2}$ in the second equation given we get

$\frac{16-(y-3)^{2}}{16} + \frac{(y-3)^{2}}{64} = 1$

$\frac{-(y-3)^{2}}{16} + \frac{(y-3)^{2}}{64} =0$

∴ y=3

Putting y=3 in the first equation we get

$(x-2)^{2} = 16$

x-2 = ±4

Hence x=6 or x=-2.

How do I solve and whats the answer?

8090 [49]

Answer:

x = -6

Step-by-step explanation:

Here we have an equilateral triangle. All three sides have the same length, 2. Therefore, the interior angles are all equal to 60 degrees.

Therefore, 6 - 9x = 60, and -9x = 54. Dividing both sides by -9 results in

x = -54/9, or x = -6.

Identify the probability to the nearest hundredth that a point chosen randomly inside the rectangle is in the triangle. HELP PLE

sashaice [31]

Answer:

$0.02$

Step-by-step explanation:

we know that

The probability that a point chosen randomly inside the rectangle is in the triangle is equal to divide the area of the triangle by the area of rectangle

Let

x-----> the area of triangle

y----> the area of rectangle

P -----> the probability

$P=x/y$

Find the area of triangle (x)

$A=(1/2)(5)(2)=5\ in^{2}$

Find the area of rectangle (y)

$A=18*12=216\ in^{2}$

Find the probability P

$P=5/216=0.02$
