The sides are AB, BC, and AC. AC is about 1.48 in length. The angles are A B and C and are unknown other than angle B is 90 degrees.

A to B is 5, A to C is 9, and B to C is 3

The company matches up to 8%.

Multiply her salary by 8%:

66410 x 0.08 = $5,312.80

Her company will match 50% ( which is half the amount)

Divide the 8% total by 2:

5312.80 / 2 = 2656.40

The answer is B.

Answer:

Maximum error for viscosity is 17.14%

Step-by-step explanation:

We know that everything is changing with respect to the time, "r" is changing with respect to the time, and also "p" just "v" will not change with the time according to the information given, so we can find the implicit derivative with respect to the time, and since

$n = (\frac{\pi}{8}) (\frac{pr^4}{v})\\$

The implicit derivative with respect to the time would be

$\frac{dn}{dt} = \frac{\pi}{8} ( \frac{r^4}{v} \frac{dp}{dt} + \frac{4pr^3}{v}\frac{dr}{dt} )$

If we multiply everything by dt we get

$dn = \frac{\pi}{8} ( \frac{r^4}{v} dp + \frac{4pr^3}{v} dr})$

Remember that the error is given by $\frac{dn}{n}$ therefore doing some algebra we get that

$\frac{dn}{n} = 4 \frac{dr}{r} + \frac{dp}{p}$

Since, r = 0.006 , dr = 0.00025 , p = 4*105 , dp = 2000 we get that

$\frac{dn}{n} = 0.1714$

Which means that the maximum error for viscosity is 17.14%.

Factor 80t - 16t = 0<br><br> help?

Alinara [238K]

I don't know if that is factor-able. It looks like you could just subtract and get 64t. which would lead to the answer being zero since you divide by zero when isolating the variable t.

Solve the equation for x:

never [62]

3x - 17 = 9x + 7

Rearrange on same sides
-17 - 7 = 9x - 3x
-24 = 6x

Divide by 6 on either sides to isolate 6
$-\frac{24}{6} = \frac{6x}{6}$
6 and 6 cancels out
-4 = x

Answer is:
B. x = -4
