Consider the problem of finding the line of symmetry and vertex of the quadratic equation f(x) =x^2-8x+15 What is the error in t

Elenna [48]

$\bf \textit{ vertex of a vertical parabola, using coefficients}\\\\
\begin{array}{llccll} f(x) = &{{ 1}}x^2&{{ -8}}x&{{ +15}}\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}\qquad 
\left(-\cfrac{{{ b}}}{2{{ a}}}\quad ,\quad {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}\right)
\\\\\\
\textit{so the line of symmetry will be at }x=-\cfrac{{{ b}}}{2{{ a}}}$

Answer:

44.1

Step-by-step explanation:

Cosine = Adjacent over Hypotenuse

Adjacent of ∠T = 28 and hypotenuse = 39

Which means that $cos(x)=\frac{28}{39}$

Now we solve for x

To get rid of the "cos" we take the inverse of cos ( which is $cos^-^1$ ) and apply it to each side

$cos^-^1((cos)x) = x\\cos^-^1(\frac{28}{39} )=44.11461855$

We're left with x = 44.11461855

Our last step is to round to the nearest tenth and we get that the answer is 44.1

9. A company’s marginal cost function is where x is the number of units. Find the total cost of producing units 144 to 625.

Anettt [7]

Answer:

total cost is $2444

Step-by-step explanation:

A company’s marginal cost function $MC= \frac{94}{\sqrt{x} }$ is where x is the number of units

Marginal cost function is the derivative of cost function

to find the total cost of producing units , take integral of marginal cost function

$\int\limits ^{625}_{144}{\frac{94}{\sqrt{x} } } \, dx$

$94(2\sqrt{x} )$ with intervals 144 to 625

now plug in the values

$94(2\sqrt{625})-94(2\sqrt{144})=2444$

total cost is $2444
