Arjun should have divided both sides of the equation by 7 instead of multiplying.

1. The most massive planet in the solar system, Jupiter, has a mass of about 1,898,000,000,000,000,000,000,000,000 kg. Estimate

UNO [17]

Answer:

D. $2*10^{27} kg$

Step-by-step explanation:

Mass of Jupiter is given as 1,898,000,000,000,000,000,000,000,000 kg

Estimating this to the nearest whole number would be = 2,000,000,000,000,000,000,000,000,000 kg (rounding up the the "1,898")

To express this in scientific notation form, simply count how many zeros we have to the nearest whole number, 2.

We have 27 zeros there.

Therefore, we would multiply the whole number, 2, by 10 raise to the power of 27.

An estimate of the mass of Jupiter = $2*10^{27} kg$

Select all the expressions that are equivalent to the polynomial below.

katrin2010 [14]

The answers are: D and C and A and E
because:

B 3(x - 5) - 2(6x2 + 9x + 5)=−12x^2−15x−25

F (4x2 - 13x - 7) - (16x2 + 9x - 5)=−12x2−22x−2

E (-15x2 + 9x - 10) + (3x2 - 10x - 5)=−12x^2−x−15

Answer:

2. quadrant 4

3. quadrant 2

4. quadrant 3

Step-by-step explanation:

You can refer to the picture.

2. Since $tan\theta$ less than 0 which means $tan\theta$ is negative, $sin\theta$ less than 0 which means $sin\theta$ is negative.

So, the angle lies in quadrant 4 (Cos quadrant)

3. Since $tan\theta$ less than 0 which means $tan\theta$ is negative, $cos\theta$ less than 0 which means $cos\theta$ is negative.

So, the angle lies in quadrant 2 (Sin quadrant)

4. Since $tan\theta$ more than 0 which means $tan\theta$ is positive, $sin\theta$ less than 0 which means $sin\theta$ is negative.

So, the angle lies in quadrant 3 (tan quadrant)
