Answer:

x= 1.71

Step-by-step explanation:

We need to isolate x in the equation, first subtract 70 from the left side, so the equation is, - $2^{3x\\}$ =-35. There is a negative sign in both equations so we cancel them out so our equation is $2^{3x\\}$ =35. Now we use log, so our equation now looks like {log(35)/log(2)}/3=x. When we do it out we get that x=1.70976, and when rounded we get, x-1.71.

(01.04 MC)The elevation of city A is 80 feet below sea level; the elevation of city C is 16 feet below sea level. The elevation

fomenos

A) The expression to represent the elevation in feet of city D is; ¹/₂ × (-16) ft

B) The solution to the expression of the elevation of City D is; -8 fr which is negative because it falls below sea level.

First of all, sea level is at 0 ft.

Thus;

If city A has an elevation of 80 ft below sea level, then;

Elevation of city A = -80 ft

The elevation of city C is 16 feet below sea level. Thus;

Elevation of city C = -16 ft

A) The elevation of city D is ¹/₂ of the elevation of city C. Thus;

Expression for Elevation of city D = ¹/₂ × (-16)

B) Solving the expression for elevation of city D gives;

Elevation of City D = -8 ft

The reason why the answer is negative is because any distance below sea level is considered to be negative and city C which is twice the elevation of city D is negative, and so city D must also have a negative elevation.

Which of the following is the simplified expression of 2 square root of -16 + the square root of 225 in standard form, a plus b

LuckyWell [14K]

Answer:

<em>The standard form like $(a+bi)$ will be: $15+8i$ </em>

Step-by-step explanation:

Given expression is: $2\sqrt{-16}+\sqrt{225}$

First factoring out -16 as (-1×16) , we will get....

$2\sqrt{-1}*\sqrt{16}+\sqrt{225}$

Now, replacing $\sqrt{-1}$ as $i$ .......

$2i\sqrt{16}+\sqrt{225}$

Finally, simplifying the radicals in the above expression, we will get......

$2i*4+15\\ \\ =15+8i$

Thus, the standard form like $(a+bi)$ will be: $15+8i$
