Answer: 2b + 56.8 = 180.4

How I Got The Answer: To represent the number of the mass of a beaker, use the number <em>b</em>. Since the problem says, <em>"Two beakers </em><u><em>plus</em></u><em> their contents have a mass of 180.4 (the contents being 56.8)," </em>create the equation 2b + 56.8 = 180.4.

If you need to solve it, subtract 56.8 from both sides, canceling out 56.8 on the left side and turning 180.4 to 123.6. All you need to do now is divide 2 from each side, and you now have b = 61.8.

Solve for the problem 13^3x-1=91
gogolik [260]

Answer:

{13}^{3} x - 1 = 91 \\  {13}^{3}x = 91 - 1 \\  {13}^{3}x   = 90 \\  2,197x = 90 \\  \frac{2197x}{2197}  =  \frac{90}{2197}  \\ x = 0.04

A • (-3,-4)<br> B • (5,2)<br> C • (11,-6)<br> What is BC?<br> A.) 10 <br> B.) 8<br> C.) 3<br> D.) 5
guapka [62]

Answer:

A.) 10

Step-by-step explanation:

So draw the points on a graph is the best way to solve the problem, but if you can't then you have to mentally imagine it.

on the X axis B is 5 and C is 11 so the distance or length of the line between the points is 11-5=6

on the Y axis B is 2 and C is -6 so the distance or length of the line between the points is 2-(-6)=8

now you have two lines that can make a right triangle and use the Pythagorean theorem to solve for the long line connecting directly from point B to point C x^{2}+y^{2}=z^{2} so 6^{2}+8^{2}=100=z^{2}, z=\sqrt{100}=10

Use fundamental theorem of calculus to find derivative of the function LOOK AT PHOTO
kykrilka [37]

Let c > 0. Then split the integral at t = c to write

f(x) = \displaystyle \int_{\ln(x)}^{\frac1x} (t + \sin(t)) \, dt = \int_c^{\frac1x} (t + \sin(t)) \, dt - \int_c^{\ln(x)} (t + \sin(t)) \, dt

By the FTC, the derivative is

\displaystyle \frac{df}{dx} = \left(\frac1x + \sin\left(\frac1x\right)\right) \frac{d}{dx}\left[\frac1x\right] - (\ln(x) + \sin(\ln(x))) \frac{d}{dx}\left[\ln(x)\right] \\\\ = -\frac1{x^2} \left(\frac1x + \sin\left(\frac1x\right)\right) - \frac1x (\ln(x) + \sin(\ln(x))) \\\\ = -\frac1{x^3} - \frac{\sin\left(\frac1x\right)}{x^2} - \frac{\ln(x)}x - \frac{\sin(\ln(x))}x \\\\ = -\frac{1 + x\sin\left(\frac1x\right) + x^2\ln(x) + x^2 \sin(\ln(x))}{x^3}
