Answer:

It is an imaginary number.

Step-by-step explanation:

The square root of negative one is "i," the imaginary number. This concept is immensely useful in mathematics, as it allows for there to be square roots of negative numbers, which is otherwise not possible using only real numbers.

Any number that includes a negative square root is called an imaginary number. For example, the square root of -9 equals 3i, an imaginary number. When an imaginary number and a real number are combined, for example 2 + 3i, this is called a complex number. Complex numbers have many real world applications, including manipulating sound waves and calculating electrical currents.

A triangle T is bounded (on three sides) by the lines x = 6, y = 0, and y = 3 2 x. A rectangle of width w is inscribed inside T.
Viktor [21]

Answer:

33.85 units^2

Step-by-step explanation:

you must first draw the triangle on the plane using the equations (see

attached file), you will have a right angle triangle with a height of 192 and a base of 6.

then you calculate the angle with the tangent function = 88.21

Then you use the small triangle to find the value of a (see attached file).

Finally, you propose an equation for X to find one of the sides of the triangle, once you have x squared it, and you already have the area,

i attached procedure

Solve each problem using a formula for perimeter or area<br> ill give brainliest!!!!!
Karolina [17]

Answer:

12) s=\frac{p}{5}

13) A=wh

14) p=a+b+c

15) A=\frac{bh}{2}

16) p-b-c=a

Step-by-step explanation:

12) \frac{p}{5} =\frac{5s}{5}

13) \frac{A}{h}=W (multiply both sides by h)

14) take c to the other side of the equation( other side of the equal sign) it becomes a positive value

15) Divide both sides by 2

16) take b + c to the other side of the equation where it becomes -b-c
