D:x-4>0 \wedge x+3>0 \wedge x>0\\
D:x>4 \wedge x>-3 \wedge x>0\\
D:x>4\\\\
\log(x-4)+\log(x+3)=2\log x\\
\log(x-4)(x+3)=\log x^2\\
(x-4)(x+3)=x^2\\
x^2+3x-4x-12=x^2\\
-x=12\\
x=-12\\
-12\not\in D\\
\Downarrow\\
\boxed{x\in\emptyset}

Y = 3^x 

To the x power.

y = 3^(1) = 3
y = 3^(2) = 9
y= 3^(3) = 27 and so on...

Helppppppp pleaseeee
Nat2105 [25]

Answer:

2

Step-by-step explanation:

The Y intercept is where x is = to zero.

If x is zero that is one section of the chart back.

so 1 would be subtracted from Y.

You have 200 meters of fencing. What triangle will result in the maximum fence-able area? What is that area?
ikadub [295]

Answer:

It will be an equilateral triangle and the area is 1924.5 sq. meters.

Step-by-step explanation:

If the total length of the fencing of 200 meters is utilized then the perimeter of the triangle will be 200 meters.

Now, we know that the type of triangle that gives the maximum area for a given perimeter is an equilateral triangle.

So, the equilateral triangle with a perimeter of 200 meters will have side lengths of \frac{200}{3} meters.

Now, the area of an equilateral triangle with sides a units is given by \frac{\sqrt{3}}{4} a^{2} sq. units.

So, the area of the above equilateral triangle will be = \frac{\sqrt{3}}{4}\times (\frac{200}{3})^{2} = 1924.5 sq. meters. (Answer)

The two tables give the number of pints of blue and yellow that are used to make different amounts of two shades of green dye.
abruzzese [7]

In the two highlighted rows show that for the same amount of yellow, Green #1 uses more blue than Green #2 and green #1 is bluer shade of green than Green # 2.

<h3>What is ratio of two numbers?</h3>

The ratio of two number is the fraction part, which represent that how a number is more or less compare to the other.

There are two tables which give the number of pints of blue and yellow that are used to make different amounts of two shades of green dye. The table is given below;

  • Green #1 is made by mixing blue and yellow in a ratio of 2 : 3.
  • Green #2 is made by mixing blue and yellow in a ratio of 1 : 2.

The first one has 2 parts of blue at 3 parts of yellow. In the two highlighted rows show that for the same amount of yellow, Green #1 uses more blue than Green #2.

In grade two the blue part is half of the yellow part. This means that green #1 is bluer shade of green than Green # 2.

Hence, in the two highlighted rows show that for the same amount of yellow, Green #1 uses more blue than Green #2 and green #1 is bluer shade of green than Green # 2.

17. Which of the following is the correct formula for finding power in a DC circuit? A. P = I2R B. P = VR C. P = IR D. P = V2I
netineya [11]

Answer:

Choice A. P = I² · R where

  • P is the power in the DC circuit,
  • I is the current through the circuit, and
  • R is the total resistance of the circuit.

Step-by-step explanation:

Electrical power is the rate at which the electrical force does work. So what is electrical work? That's the work W that the electrical force do when it moves charges Q across a potential difference V:

W = V\cdot Q.

The power is the rate at which the electrical force do the work:

\displaystyle P = \frac{W}{t} = V \cdot \frac{Q}{t}.

On the other hand, current I is the charge through a cross-section of the circuit in unit time. By the definition of current:

\displaystyle\frac{Q}{t} = I.

\displaystyle P =V \cdot \frac{Q}{t} = V\cdot I.

Consider Ohm's Law:

V = I \cdot R.

Therefore

\displaystyle P = V\cdot I = (I \cdot R) \cdot I = I^{2}\cdot R.
