kiruha [24]

Answer:

k = -7

Explanation:

Given

f(x) = 5^x through (0,1) and (1,5)

g(x) = 5^x + k through (0,-6) and (1,-2)

Required

Determine the value of k if f(x) is translated vertically down

To get the value of k, we perform the following operations.

For (0,-6) --- Substitute 0 for x and -6 for g(x) in g(x) = 5^x + k

g(x) = 5^x + k

-6 = 5^0 + k

-6 = 1 + k

k + 1 = -6

k = -6 - 1

k = -7

For (1,-2) --- Substitute 1 for x and -2 for g(x) in g(x) = 5^x + k

g(x) = 5^x + k

-2 = 5^1 + k

-2 = 5 + k

k+5 = -2

k= -2-5

k = -7

To further show that k = -7, we have the following:

f(x) = 5^x

When translated downward by 7 units, the function becomes

g(x) = f(x) - 7

Recall that: g(x) = 5^x + k and f(x) = 5^x

So, we have:

5^x + k = 5^x - 7

Subtract 5^x from both sides

5^x - 5^x + k = 5^x - 5^x + 7

k = -7

What planet can come closest to the earth in its orbit and look brightest in our skies?
Naya [18.7K]

Venus can come closest to the earth in its orbit and look brightest in our skies.

Venus is extremely bright because it is the nearest planet to Earth and because most of the sunlight that reaches it (about 70%) is reflected back into space by its thick clouds. The brightest object in the sky, Venus is frequently seen within a few hours after sunset or before sunrise.

The Earth and Venus is 38 million kilometres away at the closest point of opposition. This is the planet's closest approach to Earth. Venus has never travelled more than 261 million kilometres from Earth. the fact that the distance between Venus and Earth may change by a staggering 223 million kilometres.
