Answer:

Step-by-step explanation:

Both of the y= make upward parabolas

It is also going into the positive direction so it is $x = \frac{1}{4}y^2$

Answer:

1/4 y^2 =x

Step-by-step explanation:

The equation for a horizontal parabola is

(y - k)^2 = 4p(x - h)

The vertex is (0,0).

Substituting that in

(y - 0)^2 = 4p(x -0)

(y )^2 = 4p(x)

Since this opens to the right, p is positive

y^2 = 4px

Divide each side by 4

1/4 y^2 = px

Letting p =1

1/4 y^2 =x

Answer:

B. y = 10(2)^x

Step-by-step explanation:

y = ab^x

to find "b" divide the function at x = 3 by the function at x = 2

80 = ab^3

——————

40 = ab^2

This results in

2 = b

to find "a" plug pickany value of x

using x = 2

40 = a(2²)

40 = a(4)

a = 10

With a = 10 and b = 2 the exponential function y = ab^x is

y = 10(2)^x

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

kvasek [131]

From 170 to 97, there's a difference of 73.

so hmm if we take 170 to be the 100%, what is 73 in percentage off of it?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
170&100\\
73&p
\end{array}\cfrac{170}{73}=\cfrac{100}{p}\implies p=\cfrac{73\cdot 100}{170}$
