Answer:

B

Step-by-step explanation:

Substitute the given values for x and y into the expression

\frac{20}{5} - \frac{8}{2} + \frac{3(2)(5)}{2+5}

= 4 - 4 + \frac{30}{7}

= 0 + \frac{30}{7}

= \frac{30}{7} = 4 \frac{2}{7}

What conclusions can be drawn about finding the quotient in scientific notation? Check all that apply. Start Fraction (9.6 times
bija089 [108]

Answer:

B.The exponent of the solution is –12, the difference of the original exponents.

C.The coefficient of the solution must be greater than or equal to one but less than 10.

D.The quotient is 3.0 × 10^{-12}

Step-by-step explanation:

We are finding the quotient of the expression below in scientific notation

\dfrac{9.6X10^{-8}}{3.2X10^4} \\=\dfrac{9.6}{3.2}X10^{-8-4}\\ =3 X 10^{-12}

The following conclusions can be drawn

B.The power of 10 in the solution is –12, the difference of the original exponents.

C.The coefficient is 3, which is greater than or equal to one but less than 10.

D.The quotient is 3.0 × 10^{-12}

PLEASE help me with this question! This is really urgent! No nonsense answers please.
ipn [44]

Answer:

The second table of values.

Step-by-step explanation:

Let's put the x-values in the second table of values in correct number order:

x: -3, -2, -1, 0, 1

Now, let's write out the y-values in correct number order:

y: 1/4, 1, 4, 16, 64

Finally, let's rewrite the second table of values with the x-values in order and the corresponding y-values underneathe:

x: -3,  -2,  -1  0  1

y: 64,  16,  4, 1,  1/4

As it can be seen, as the x-values get bigger in value, the y-values get smaller exponentially, which is the definition of exponential decay.

SIZIF [17.4K]

Answer:

5040

Step-by-step explanation:

You get this number by using the mathematical process of factorials.

Since <em>history </em>has seven words, we will solve seven factorial.

7! = 5040
