Mathematics
1 answer:
AfilCa [17]3 years ago
5 0

Answer:

Left side

Ca(OH)2 --> Ca + 2 O + 2 H

2 HBr --> 2 H + 2 Br

Together: Ca + 2 O + 4 H + 2 Br

You have only 1 Br and only 3 H. So you must correct this.

Which inequality represents all values of x for which the product below is defined
zavuch27 [327]

Answer:

(-∞, -2) ∪ (0, ∞)

Step-by-step explanation:

Multiply together the (7x) and the (x+2), obtaining 7x^2 + 14x.  This is the correct argument (input) to Answer A.

Since the domain of the square root function includes "all real numbers equal to or greater than 0," we set 7x^2 + 14x = to 0.  This factors to the original 7x*(x+2), set equal to 0.  The roots are 0 and -2.  

These two values create three intervals:  (-∞, -2), (-2, 0) and (0, ∞).

Choosing test numbers, one from each interval:  {-5, -1, 1}.

7x^2 + 14x is + at x = -5, - at x = -1, and + at x = 1.

Thus, the domain of this function is  (-∞, -2) ∪ (0, ∞).  In other words, the product shown is defined on  (-∞, -2) ∪ (0, ∞).

Find the missing angle.
cestrela7 [59]

Answer:

85 degrees

Step-by-step explanation:

The angles in a quadrilateral add to 360 degrees, so x+109+96+70=360.

This means that x=360-109-96-70=85 degrees

Evaluate the expression. [(3–5)(34)]3 1 Innermost group, apply the product of powers: [3–1]3 2 Apply the power of a power: 3–3 3
Otrada [13]

Answer:

x=27

Step-by-step explanation:

To evaluate the expression: [(3^{-5})(3^4)]^3

Step 1:  Innermost group, apply the product of powers (a^x \times a^y =a^{x+y}

Therefore:

(3^{-5})(3^4)=3^{-5+4}=3^{-1}

We then have:

=[3^{-1}]^3

Step 2: Apply the power of a power

[3^{-1}]^3=3^{-1 \times 3} =3 ^{-3}

Step 3: Apply the negative exponent

3 ^{-3} =\dfrac{1}{3^3}

Step 4: Simplify

\dfrac{1}{3^3}=\dfrac{1}{27}

Therefore, the value of x in the simplified expression is 27.
