-7c+9=c+1 <br> If you could also show how you did it i would appreciate it

Step2247 [10]

-7c+9=c+1 (subtract c on both sides)
-8c+9=1 (subtract 9 on both sides)
-8c=-8 (divide by -8 on both sides to get c by its self)
c=1
your answer is 1.

Priya measured the length of lizard to be 11 cm. The actual length is 12 cm. Find the % error.

Aleksandr [31]

Answer:

8.33%

Step-by-step explanation:

Formula for percent error:

$|\frac{observed value - expected value}{expected value} | * 100%$

Using this formula, we get:

$|\frac{11-12}{12} |* 100 = \frac{100}{12} = 8.33$

The slope f′(x) at each point (x,y) on a curve y=f(x) is given, along with a point (a,b) on the curve. Use this information to f

Montano1993 [528]

$f'(x)=\dfrac{4x}{1+7x^2}$

Integrating gives

$f(x)=\displaystyle\int\frac{4x}{1+7x^2}\,\mathrm dx$

To compute the integral, substitute $u=1+7x^2$ , so that $\frac27\,\mathrm du=4x\,\mathrm dx$ . Then

$f(x)=\displaystyle\frac27\int\frac{\mathrm du}u=\frac27\ln|u|+C$

Since $u=1+7x^2>0$ for all $x$ , we can drop the absolute value, so we end up with

$f(x)=\dfrac27\ln(1+7x^2)+C$

Given that $f(0)=10$ , we have

$10=\dfrac27\ln1+C\implies C=10$

so that

$\boxed{f(x)=\dfrac27\ln(1+7x^2)+10}$
