Answer:

\boxed{3^9}

Step-by-step explanation:

3^5 \times 3^4

Apply the law of exponents : a^b \times a^c = a^{b+c}

The exponent product rule states that, when multiplying two exponents that have the same base, you can add the exponents.

3^{5+4}

3^9

Nutka1998 [239]

Answer:

1900

Step-by-step explanation:

1 kg = 1000g

1.2kg = x

<u>1</u><u> </u><u>kgx</u> = <u>1</u><u>2</u><u>0</u><u>0</u><u> </u><u>kg.g</u>

1kg. 1kg

x = 1200 g

1 decagram = 10g

40 decagram = x

<u>1</u><u> </u><u>dg.x</u> = <u>4</u><u>0</u><u>0</u><u> </u><u>dg.g</u>

1 dg. 1 dg

x = 400g

so the total= 1200g +300 + 400g=1900g

without the unit = 1900

The derivative of f(x) = 2\cdot x^{2}-9 is f'(x) = 4\cdot x.

In this exercise we must apply the definition of derivative, which is described below:

f'(x) =  \lim_{x \to 0} a_n \frac{f(x+h)-f(x)}{h} (1)

If we know that f(x) = 2\cdot x^{2}-9, then the derivative of the expression is:

f'(x) =  \lim_{h \to 0} \frac{2\cdot (x+h)^{2}-9-2\cdot x^{2}+9}{h}

f'(x) = 2\cdot \lim_{h \to 0} \frac{x^{2}+2\cdot h\cdot x + h^{2}-2\cdot x^{2}}{h}

f'(x) = 2\cdot  \lim_{h \to 0} 2\cdot x + h

f'(x) = 4\cdot x

The derivative of f(x) = 2\cdot x^{2}-9 is f'(x) = 4\cdot x.

Answer:

Option B

Step-by-step explanation:

we know that

One ounce of cottage cheese is equivalent to 28.25 grams

1/2 cup serving of cottage cheese is equivalent to 125 grams.

so

By proportion

\frac{1}{28.25}\frac{ounce}{grams}=\frac{x}{125}\frac{ounce}{grams}\\ \\x=125/28.25\\ \\x=4.42\ ounces
