Lera25 [3.4K]3 years ago
6 0

Answer:

The exponential function y = 2 ^ x has these properties:

A.  The domain is the set of all real numbers.

B.  The range is zero to infinity, (0, ∞).  

C.  The graph appears in Quadrants I and II and never touches the x-axis.

D.  The function is always positive.

E.  The inverse function of y = 2 ^ x is found b)y interchanging x and y here and solving x = 2^y for y: taking the natural log (ln) of both sides, ln x = y ln 2, so that y = (ln x) / (ln 2)

The above (E) can only be done if x is positive.

A company is giving gifts to its employees. Employees can choose a gift card, hat, or candy. The table shows the gift chosen by
Paraphin [41]

Answer:

360 Employees

Step-by-step explanation:

Number of employees who chose gift card / Number of total employees

= 90 / 150

Now, we have to figure out in x / 600 when the x represents the number of employees choosing gift card when there are 600 employees in total.

90 / 150, x / 600

-> cross multiply

54,000 = 150x

Therefore 360 = x.

another way:

(multiply the total number of employees in both ratios) 600 / 150 = 4

Now we multiply 4 by 90 (number of employees choosing gift card)

4*90 = 360

(x-5)(x^2+4x-2)<br><br> PLEASE HELP
ANEK [815]

Answer:

Simplifed (X-5)(x^2+4x-2) = x^3 − x^2 − 22x + 10

Step-by-step explanation:

Expand ( x − 5 ) ( x^2 + 4x − 2 ) by multiplying each term in the first expression by each term in the second expression.

x ⋅ x^2 + x (4x) + x ⋅ −2 −5x^2 − 5 (4x) −5 ⋅ −2

Simplify terms.

x^3 − x^2 − 22x + 10

I hope this helps.
