Answer:

Simplest form = 4z + 21

Case 1: True, Case II: false and Case III: true

Step-by-step explanation:

18z - 7( -3 + 2z)

= 18z + 21 - 14z

= 18z -14z + 21

= 4z + 21

So, in the above expression we have two terms. First term is 4z and second term is 21.

So the first case is true. As the expression has two terms.

The coefficient of z is a number which is multiplied by z. Therefore, Second case is false as the coefficient of z is 4.

The constant is a number which is not multiplied by any variable. Therefore, third case is true as the constant number in above expression is 21.

Graph the inverse circular function by hand, given f(x) = 3sin(2x) ;-pi/4 ≤ ≤pi/4

nasty-shy [4]

Part a)

a) The given function is

$f(x) = 3 \sin(2x)$

We let

$y = 3 \sin(2x)$

Interchange x and y.

$x= 3 \sin(2y)$

Solve for y;

$\frac{x}{3} = \sin(2y)$

$y = \frac{1}{2} { \sin}^{ - 1}( \frac{x}{3} )$

${f}^{ - 1}(x) = \frac{1}{2} { \sin}^{ - 1}( \frac{x}{3} )$

Part b) The range of f(x) refers to y-values for which f(x) exists.

The range of f(x) is

$- 3 \leqslant y \leqslant 3$

This is because the function is within y=-3 and y=3.

c) The range of

${f}^{ - 1} (x)$

$- \frac{ \pi}{4} \leqslant y \leqslant \frac{\pi}{4}$

The domain is -3≤x≤3

This is because the domain and range of a function and its inverse swaps.

Part d) The graph is shown in the attachment.

Between 10 a.M. And 11 a.M., 48 people came into Brad's store. 40 of them made a purchase. What is the experimental probability

irina [24]

Answer: The required probability is $\dfrac{5}{6}$

Step-by-step explanation:

Since we have given that

Number of people came into Brad's store = 48

Number of them made a purchase = 40

So, the experimental probability that the next person to come into the store will make a purchase would be

$\dfrac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}\\\\=\dfrac{40}{48}\\\\=\dfrac{5}{6}$

Hence, the required probability is $\dfrac{5}{6}$
