Answer:

Step-by-step explanation:

Hello!!!

from the problem statement we can infer that Jamal had a container of water where he fetches from to fill the graduated cylinder.

More so, after some couple of trails he recorded as follows

25.85, 24.1, and 24.56.

Hence the total amount of water he measured out of the container after three trials is

25.85+24.1+24.56= 74.51 ml

(assuming the cylinder is calibrated in ml)

<em>The total volume of water he measures is 74.51 ml</em>

The total source voltage in the circuit is 6-3i V. What is the voltage at the middle source

Bezzdna [24]

Answer:

<em>The voltage at the middle source is</em> $(2-4\mathbf{i})\ V$

Step-by-step explanation:

<u>Voltage Sources in Series</u>

When two or more voltage sources are connected in series, the total voltage is the sum of the individual voltages of each source.

The figure shown has three voltage sources of values:

$2 + 6\mathbf{i}$

$a + b\mathbf{i}$

$2 - 5\mathbf{i}$

The sum of these voltages is:

$V_t=4+a+(6+b-5)\mathbf{i}$

Operating:

$V_t=4+a+(1+b)\mathbf{i}$

We know the total voltage is $6-3\mathbf{i}$ , thus:

$4+a+(1+b)\mathbf{i}=6-3\mathbf{i}$

Equating the real parts and the imaginary parts independently:

4+a=6

1+b=-3

Solving each equation:

a = 2

b = -4

The voltage at the middle source is $(2-4\mathbf{i})\ V$

If the area of a circle measures 9π cm2, what is the circumference of the circle in terms of π?

8_murik_8 [283]

Answer: option B

Step-by-step explanation:

The circumference of a circle can be calculated with this formula:

$C=2\pi r$

Where "C" is the circumference of the circle and "r" is the radius of the circle.

The area of a circle can be calculated with:

$A=\pi r^2$

Where "r" is the radius.

Knowing the area, you can solve for the radius:

$r^2=\frac{9\pi cm^2}{\pi }\\\\r=\sqrt{\frac{9\pi cm^2}{\pi } }\\\\r=3cm$

Substituting into $C=2\pi r$ , you get that the circumference of this circle is:

$C=2\pi (3cm)=6\pi\ cm$
