Find g(4x) g(x)=x²-4

7nadin3 [17]

Answer:

g(x) = x² - 4 is already in form of a variable, I.e., x

g(4x) takes another variable, I.e., 4x

Same as before, 4x takes over x:

=> g(4x) = (4x)² - 4

(ax)² = a²x², where a is some arbitrary constant.

<h3>Answer: </h3>

=> g(4x) = 16x² - 4

=> g(4x) = 4{4x² - 1}

Answer:

d/c = 8

Step-by-step explanation:

f(x) = 5.4321×2^×

f(4) = 5.4321×2^4 = d

f(1) = 5.4321×2^1 = c

d/c = (5.4321×2^4)/(5.4321×2^1) = 2^3 = 8

If f(x) = 2x + 1 and g(x) = x2 + 5, what is g(f(2))?

Amiraneli [1.4K]

Answer:

30 if that is an $x^{2}$ in g(x)

Step-by-step explanation:

f(2) = 2x + 1

= 2(2) + 1

= 4 + 1

f(2) = 5

g(5) = $x^{2}$ + 5

= $5^{2}$ + 5

= 25 + 5

g(5) = 30

Mabel, Adeline and Charlie share 34500ft2 of land Mabel ownes 26%of the land area and Adeline Owens 47% of the land area . What

NikAS [45]

Answer:

Charlie owns 9,315 ft2 of the land area

Step-by-step explanation:

There are 34,500 ft2 of land shared between Mabel, Adeline, and Charlie.

Mabel owns 26% of the land area, that is:

26*34,500 ft2 / 100 = 8,970 ft2

Adeline owns 47% of the land area, or:

47*34,500 ft2 / 100 = 16,215 ft2

The land owned by Mabel and Adeline is: 8,970 ft2 + 16,215 ft2 = 25,185 ft2

Since the total area land is 34,500 ft2, Charlie owns:

34,500 ft2 - 25,185 ft2 = 9,315 ft2

Charlie owns 9,315 ft2 of the land area
