Answer:

Your correct answer is -24

Step-by-step explanation:

(3)(−4)(2)

= (−12)(2)

= −24

Answer:

False

Step-by-step explanation:

1/3^4=3^4

0.012346≠81

False

Answer:

True

Step-by-step explanation:

The negative power property of exponents says that:

[tex]x^{-n}=\frac{1}{x^n}[/tex]

And vice versa:

[tex]\frac{1}{x^{-n}}=x^n[/tex]

Therefore, since our exponent is negative, we can change it to positive if we put it in the numerator. In other words:

[tex]\frac{1}{3^{-4}}=3^4[/tex]

The statement is true.

Answer:

-24 a^2 b^7

Step-by-step explanation:

Simplify the following:

-8×3 a^2 b^4 b^3

Hint: | Combine products of like terms.

3 a^2 b^4 (-8) b^3 = 3 a^2 b^(4 + 3) (-8):

-8×3 a^2 b^(4 + 3)

Hint: | Evaluate 4 + 3.

4 + 3 = 7:

-8×3 a^2 b^7

Hint: | Multiply 3 and -8 together.

3 (-8) = -24:

Answer: -24 a^2 b^7

Answer:

The correct answer is:

Answer:

400 feet.

Explanation:

We need to find the difference between the lowest point of Galilee and the lowest point of Death Valley. We can find this by subtracting the lowest point of Galilee by the lowest point of Death Valley. It says the lowest point of Galilee is 682 feet below sea level and the lowest point of Death Valley is 282 feet below sea level. Therefore, we subtract 682 - 282, which equals 400.

Answer:

find b: since the triangle is right angle triangle apply the Pythagorean theorem

c²+b²=d²

b²=d²-c²

b²=16²-12²

b²=256-144

b²=112

the sum of the angle of the triangle=180

( in top Δ abd ) sin Ф=opp/hyp

sinФ=b/d=4√7/16= √7/4  radian

convert to degrees : √7/4 *180/π= 37.91 almost 38 degrees

find a=?? apply law of cosine

a²= d^2 + c^2 − 2dc cosA

a²=16² + 12²-2(16)(12)cos38

a =√(16² + 12²-2(16)(12)cos38)

Answer:

[tex]x=\frac{s}{q+r}[/tex]

Step-by-step explanation:

1 Factor out the common term x

[tex]x(q+r)=s[/tex]

2 Divide both sides by q+r

[tex]x=\frac{s}{q+r}[/tex]

Answer:

S = 1

Step-by-step explanation:

If you add a positive 1 to -20, you would get -19

Answer:

S=1

Step-by-step explanation:

Add 20 to both sides:

S+(-20)=-19

+20 +20

S=1

  5.806 × 10³

Step-by-step explanation:

Put a decimal point to the right of the left-most digit: 5.806. Now multiply by the place value of that digit.

  5.806 × 10³

Answer:

Protons and neutrons each count for one AMU, and the electron counts for zero AMU. So, if the atomic mass of oxygen is 16, that means we have a total of 16 protons and neutrons. 16 total protons and neutrons minus 8 protons leaves us with 8 neutrons.

Answer:

x = 2 and x = -1

Step-by-step explanation:

The zeroes of the function are found by setting g(x) equal to 0:

g(x) = (x - 2)(3x + 3) = 0

By the Zero Product Property, in order for this equation to be equal to 0, each of (x - 2) or (3x + 3) or both has to equal 0. So, set each equal:

x - 2 = 0

x = 2

3x + 3 = 0

3x = -3

x = -3/3 = -1

The zeroes are thus x = 2 and x = -1.

Answer:

m = 1/2

Step-by-step explanation:

Use two points on the line given.

(0 , 2) & (-4 , 0)

You are solving for the slope. The slope formula:

m (slope) = (y₂ - y₁)/(x₂ - x₁)

Let:

(x₁ , y₁) = (-4 , 0)

(x₂ , y₂) = (0 , 2)

Plug in the corresponding numbers to the corresponding variables:

m = (2 - 0)/(0 - (-4))

Simplify:

m = (2)/( 0 - (-4))

m = (2)/(0 + 4)

m = 2/4

Simplify the slope. Divide the common factor 2 from both the numerator and denominator:

m = (2/4)/(2/2) = 1/2

1/2 is your slope.
