Kendra sold 200 shares through her broker on June 8. The price per share was $22.10. The broker charged her a 0.5% commission on

KiRa [710]

Answer:

A. $4397.9

Explanation:

We are given that Kendra sold 200 shares and that the price per share was $22.1

This means that:

Total value = 200 * 22.1 = $4420

Now, we know that the broker charged 0.5% commission on the total value

This means that:

Broker's charge = 0.5% * 4420 = 0.005 * 4420 = $22.1

Therefore,

Kendra's return = Total value - broker's charge

Kendra's return = 4420 - 22.1 = $4397.9

Hope this helps :)

Please help I’m stuck!!!

Answer:

The value of angle B is 33.69°

Step-by-step explanation:

You can find out using Tangent Rule, tanθ = oppo./adj. where opposite and adjacent are the length of triangle :

oppo. = AC = 6 units

adj. = BC = 9 units

θ = ∠B

tan ∠B = AC/BC

tan ∠B = 6/9

∠B = tan^(-1) (6/9)

= 33.69° (near. hundredth)

Help please 25 pts. I will mark. One month Justin rented 2 movies and 5 video games for a total of $32. The next month he rented

umka21 [38]

Answer:

The movie costs $3.50 and the video games cost $5.

Step-by-step explanation:

a = 1 movie

b = 1 video game

2a + 5b = $32

8a + 3b = $43

2a x -4 = -8a

5b x -4 = -20b

32 x -4 = -128

8a + 3b = $43

- 8a + 20b = $128

--------------------------------

-17b = -85

17b = 85

/17 /17

b = 5

2a + 5(5) = 32

2a + 25 = 32

- 25 = -25

----------------------

2a = 7

/2 = /2

a = 3.5

a = $3.50

b = $5

The maximum value of the function: f(x)= -5 x ^2 +30x-200 is?

VARVARA [1.3K]

Answer:

$\displaystyle - 155$

Step-by-step explanation:

we are given a quadratic function

$\displaystyle f(x) = - 5 {x}^{2} + 30x - 200$

we want to figure out the minimum value of the function

to do so we need to figure out the minimum value of x in the case we can consider the following formula:

$\displaystyle x _{ \rm min} = \frac{ - b}{2a}$

the given function is in the standard form i.e

$\displaystyle f(x) = a {x}^{2} + bx + c$

so we acquire:

b=30
a=-5

thus substitute:

$\displaystyle x _{ \rm min} = \frac{ - 30}{2. - 5}$

simplify multiplication:

$\displaystyle x _{ \rm min} = \frac{ - 30}{ - 10}$

simply division:

$\displaystyle x _{ \rm min} = 3$

plug in the value of minimum x to the given function:

$\displaystyle f (3)= - 5 {(3)}^{2} + 30.3 - 200$

simplify square:

$\displaystyle f (3)= - 5 {(9)}^{} + 30.3 - 200$

simplify multiplication:

$\displaystyle f (3)= - 45 + 90- 200$

simplify:

$\displaystyle f (3)= - 155$

hence,

the minimum value of the function is -155
