No hablo expanol

7(z+2)-3z=44
7z+14-3z=44
7z-3z+14=44
4z+14=44
-14        -14
4z+14-14=44-14
4z+0=30
4z=30
1/4  1/4
(4z)/4=30/4
(4/4)z=15/2
1z=15/2
z=15/2



z=15/2

<em>Answer:</em>

<em>63°</em>

<em>Step-by-step explanation:</em>

<em>Hi there ! </em>

<em>ABCD parallelogram => ∡A = ∡C</em>

<em>13x - 41 = 6x + 15</em>

<em>13x - 6x = 15 + 41</em>

<em>7x = 56</em>

<em>x = 56 : 7</em>

<em>x = 8</em>

<em>∡C = 6×8 + 15 = 48 + 15 = 63°</em>

<em>Good luck !</em>

Prove Euler's identity using Euler's formula.<br> e^ix = cos x + i sin x
Korolek [52]

First list all the terms out.

e^ix = 1 + ix/1! + (ix)^2/2! + (ix)^3/3! ...

Then, we can expand them.

e^ix = 1 + ix/1! + i^2x^2/2! + i^3x^3/3!...

Then, we can use the rules of raising i to a power.

e^ix = 1 + ix - x^2/2! - ix^3/3!...

Then, we can sort all the real and imaginary terms.

e^ix = (1 - x^2/2!...) + i(x - x^3/3!...)

We can simplify this.

e^ix = cos x + i sin x

This is Euler's Formula.

What happens if we put in pi?

x = pi

e^i*pi = cos(pi) + i sin(pi)

cos(pi) = -1

i sin(pi) = 0

e^i*pi = -1 OR e^i*pi + 1 = 0

That is Euler's identity.

Un capital de 4000 lei este plasat în regim de dobândă simplă pe o perioadă de 3 ani cu rata dobânzii
9966 [12]

Answer:

960

Step-by-step explanation:

The simple interest formula is the following:

I = P*r*t

Where I is the interest generated after t years, P is the inicial value and r is the rate of interest.

In this case, we have that the inicial value is P = 4000, the rate of interest is r = 8% = 0.08 and the amount of time invested is t = 3 years.

So, the interest will be:

I = 4000*0.08*3 = 960

If you need to construct a dog run for your dog and the total perimeter needs to be 40 feet, and you only have enough room to ma
Natali [406]

Answer:

15 feet

Step-by-step explanation:

if the dog run is a rectangles then the formula for the perimeter is 2h+2l

if we plug in the numbers we know we get this:

2h+2(5)=40

2h+10=40

2h=30

h=15
