Grandma baked 96 cookies and gave them to her grandchildren. One of the grandchildren, cindy, received c fewer cookies than she

VMariaS [17]

Answer:

$12-c$

Step-by-step explanation:

We have been given that grandma baked 96 cookies and gave them to her grandchildren. One of the grandchildren, Cindy, received c fewer cookies than she would have received had all of the cookies been evenly divided among the 8 grandchildren.

Let us find the number of cookies that each grandchildren will receive, if all of the cookies been evenly divided among the 8 grandchildren by dividing 96 by 8.

$\text{When cookies are evenly divided each grandchildren will receive}=\frac{96}{8}$

$\text{When cookies are evenly divided each grandchildren will receive}=12$

Each grandchildren would have received 12 cookies, if the cookies had been evenly divided. Since Cindy got c fewer cookies, so we will subtract c cookies from 12.

Therefore, Cindy will receive $12-c$ cookies.

Find an equation of the tangent to the curve at the point corresponding to the given value of the parameter. x = cos(θ) + sin(4θ

dybincka [34]

The line tangent to the curve at $(x(0),y(0))$ has slope

$\dfrac{\mathrm dy}{\mathrm dx}\bigg|_{\theta=0}=\dfrac{\mathrm dy}{\mathrm d\theta}\dfrac{\mathrm d\theta}{\mathrm dx}\bigg|_{\theta=0}=\dfrac{\cos\theta-4\sin4\theta}{-\sin\theta+4\cos4\theta}\bigg|_{\theta=0}=\dfrac14$

Then the tangent line has equation

$y-y(0)=\dfrac14(x-x(0))$

$y-1=\dfrac14(x-1)$

$\boxed{y=\dfrac{x+3}4}$
