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

1 kgx = 1200 kg.g

1kg. 1kg

x = 1200 g

1 decagram = 10g

40 decagram = x

1 dg.x = 400 dg.g

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 $f'(x) = 4\cdot x$ .

HALP MEH PLZZZZ!

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.

By proportion

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