What is the solution of the equation 70 = 1.4y ?

1 answer:

7 0

So you basically have to divide 1.4 on both sides so you can get y by its self. Once you divide 60 by 1.4 you’ll get 50.

y=50

The complex numbers corresponding to the endpoints of one diagonal of a square drawn on a complex plane are 1 + 2i and -2 – i.Wh

Musya8 [376]

On the complex plane, the number $a+bi$ is mapped onto the point with coordinates $(a,b)$ .

In other words, the x coordinate is the real part of the number, while the y coordinate is the complex part of the number.

Viceversa, if you start from a point $(x,y)$ , you can identify the number $x + iy$ .

So, the endpoints of the diagonal are the points $(1,2)$ and $(-2,-1)$ . These are points A and C in the attached figure.

This means that points B and D have coordinates

$B = (-2,2),\quad D = (1,-1)$

So, the correspondant complex numbers are

$B = (-2,2)\mapsto -2+2i,\quad D = (1,-1)\mapsto 1-i$

Help please math answer ASAP NO LINKS

5/11 is a fraction, so it is for sure a rational number and a real number.

Since it is a fraction, it is NOT irrational (which means "not rational" or "not a fraction).

It is NOT an integer, whole number, or natural number, becuase it is only a piece of a whole. 5/11 ≈ 0.454545..., and intergers, whole numbers, and natural numbers don't involve decimals.

suppose a triangle has two sides of length 42 and 35 and that the angle.between these two sides is 120° what is the length of th

pickupchik [31]

Answer:

The length of the third side of the triangle is $7\sqrt{91}\ units$

Step-by-step explanation:

Let

c ----> the length of the third side of the triangle

we know that

Applying the law of cosines

$c^2=a^2+b^2-2(a)(b)cos(C)$

we have

$a=42\ units\\b=35\ units\\C=120^o$

substitute the given values

$c^2=42^2+35^2-2(42)(35)cos(120^o)$

$c^2=2,989-2,940cos(120^o)$

$c^2=4,459\\c=\sqrt{4,459}\ units\\c=7\sqrt{91}\ units$
