Find the zeros of the function. Write the smaller solution first, and the larger solution second. f(x)=(x+8)^2−1

BartSMP [9]

Answer:

zeroes: x = -9 and x = -7

Step-by-step explanation:

f(x)=(x+8)^2−1

A "zero" refers to when the y-value on the graph is zero.

0 = (x+8)^2 - 1

1 = (x+8)^2

+ or - 1 = x+8

so break them apart into two equations

x+8 = 1 OR x+8 = -1

x = -7 OR x = -9

You can plug both back in to check that the equation works!

What point approxmiates the square root of 10

Juli2301 [7.4K]

Answer:

Calculate the square root of 10 ( ) to 2 decimal places.

Find the two perfect square numbers it lies between. Solution: 32 = 9 and 42 = 16, so lies between 3 and 4.

Divide 10 by 3. 10/3 = 3.33 (you can round off your answer)

Average 3.33 and 3. ( 3.33 + 3)/2 = 3.1667.

A conservative estimate of the number of stars in the universe is 6 x 10^22. The average human can see about 3,000 stars at nigh

Ilia_Sergeevich [38]

$2 \times 10^{19}$ times more stars are there in universe compared to human eye can see

<h3><u>Solution:</u></h3>

Given that, conservative estimate of the number of stars in the universe is $6 \times 10^{22}$

The average human can see about 3,000 stars at night with only their eyes

To find: Number of times more stars are there in the universe, compared to the stars a human can see

Let "x" be the number of times more stars are there in the universe, compared to the stars a human can see

Then from given statement,

$\text{Stars in universe} = x \times \text{ number of stars human can see}$

<em><u>Substituting given values we get,</u></em>

$6 \times 10^{22} = x \times 3000\\\\x = \frac{6 \times 10^{22}}{3000}\\\\x = \frac{6 \times 10^{22}}{3 \times 10^3}\\\\x = 2 \times 10^{22-3}\\\\x = 2 \times 10^{19}$

Thus $2 \times 10^{19}$ times more stars are there in universe compared to human eye can see
