What is the area of triangle with base 5m and height 12m

1 answer:

5 0

The area of a triangle can be found using the formula 1/2bh, where the variable b represents the value of the base and the variable h represents the value of the height.

If we plug in the given values into this formula, we get:

(1/2)(5m)(12m)

When we simplify this expression, we get:

30 m^2

Therefore, your answer is 30 m^2.

Hope this helps!

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 $(2-4\mathbf{i})\ V$

Hi there can anyone up here that's is really good in math please help me with this question please

polet [3.4K]

I honestly think its around 250000 because 11,000 that he got for submitting and then the other cost takes the 11,000out so that leaves the 250,000 but I'm about 95% sure and the take 0.4 out of the total.

Expand: In 2a^3/b^4

dem82 [27]

Answer:

$(A)ln 2+3lna-4ln b$

Step-by-step explanation:

Given the expression: $ln \dfrac{2a^3}{b^4}$

We apply the following laws of logarithm to expand:

$Log (ab)=Log a+Log b\\Log(a/b)=Log a-Log b\\Log a^x=xLog a$

Therefore:

$ln \dfrac{2a^3}{b^4}=ln 2a^3-ln b^4\\=ln 2+lna^3-ln b^4\\=ln 2+3lna-4ln b$

Regular polygons have an even number of sides

harkovskaia [24]

No, all regular polygons does not have even number of sides.
Suppose, heptagon which is a regular polygon which has 7 sides.
But, all the sides of any regular polygon are equal in length.
