Answer:

E(c) = 15c

Step-by-step explanation:

If I earn $15 for each car i wash and my total earnings are E then we have to form a function which describes this relationship.

My earning for one car wash = $15

Similarly my earnings for c car washes = $15×c

This total earning is equal to E so function representing the equation will be E(c) = 15c

Answer is E(c) = 15c which describes the relashionship of my earnings to the number of cars i wash.

What is cos theta when sin theta = sqrt 2/3

Fittoniya [83]

Answer:

Value of cosθ is ±√7/3 .

Step-by-step explanation:

According to the Question , value of :

$\red{\implies sin\theta = \dfrac{\sqrt2}{3}}$

And , we know the identity of sine and cosine as ,

$\boxed{\pink{\sf\implies sin^2\theta + cos^2\theta = 1} }$

Using , this identity we have ;

$\implies sin^2\theta + cos^2\theta = 1 \\\\\implies \bigg( \dfrac{\sqrt2}{3}\bigg)^2 + cos^2\theta = 1 \\\\\implies \dfrac{2}{9} + cos^2\theta = 1 \\\\\implies cos^2\theta = 1 - \dfrac{2}{9} \\\\\implies cos^2\theta = \dfrac{9-2}{9} \\\\\implies cos\theta = \sqrt{\dfrac{7}{9}} \\\\\underline{\boxed{\blue{\bf \implies cos\theta = \pm \dfrac{\sqrt 7 }{3}}}}$

Now , here since θ is in 2nd quadrant and in 2nd quadrant cos is negative . Hence ,the value of cos will be :

$\boxed{\orange{\bf \implies cos\theta =-\dfrac{\sqrt7}{3}}}$

PLEASE HELP ME

natulia [17]

Answer:

Broker1 with $66.

Broker2 with $54.25

Broker4 with $50

Broker3 with $47.5

Broker5 with $33.5

Explanation :

Total number of shares Cindy have : 300

Market Price per share : $25

Total price for the shares : 300 $\times$ $25

= $7500

Now ,

Case 1:

Commission provided by broker1 = 0.75%

Online fees provided by broker1 = $ 10

Total price provided by broker1= $\frac{75}{10000}\times7500 +$10$

=$66.25

Case 2:

Commission provided by broker2= 0.5%

Online fees provided by broker2=$17

Total price provided by broker2= $\frac{5}{1000}\times 7500 + $17$

=$54.5

Case 3:

Commission provided by broker 3= 0.6% for 100 0r few

Not applicable because the total shares are 300

For over 100 shares

Commission provided= 0.5%

Online fees = $10

Total price = $\frac{5}{1000}\times 7500 + $10$

=$47.5

Case 4:

For more than 100 shares

Online fees for buying and sharing= $50

Total price = $50

Case5 :

Commision for a share bought or sold = 0.05%

Online fees =$30

Total Price= $\frac{5}{10000}\times 7500 + $30$

=$33.75
