Answer:
2.995 ou 35.940 (?)
Step-by-step explanation:
Não me lembro exatamente como fazer isso, vou mostrar duas maneiras diferentes de resolver isso.
Use a fórmula l = P * r * t
| = Juros
P = Principal
r = taxa
t = tempo
Para resolver isso, você terá que ... O principal é 29.950, a taxa é 5%, mas se tornará um decimal que é 0,05, e o tempo é 2 Coloque-o na forma de fórmula 29.950 * 0,05 * 2 = 2.995 em interesse
Ou .. Você usará a mesma fórmula, mas desta vez multiplique 0,05 por 12, pois há 12 meses em um ano que é 0,6, então ... 29.950 * 0,6 * 2 = 35.940 de juros
Espero que funcione!
Let's solve this problem step-by-step.
STEP-BY-STEP EXPLANATION:
First, we will establish that the shape of the window is a semi-circle. This means we must use the formula for the perimeter of a semi-circle to obtain the perimeter of the window.
The formula for the perimeter of a semi-circle is as follows:
Let perimeter of window or semi-circle = P
P = [ 2( Pi )r / 2 ] + 2r
Where r = radius of circle or semi-circle
From this, we will simply use the value of the radius given from the diagram in the problem and substitute it into the formula to obtain the perimeter of the window.
P = [ 2( Pi )r / 2 ] + 2r
r = 20
THEREFORE:
P = [ 2( Pi )( 20 ) / 2 ] + 2( 20 )
P = 20( Pi ) + 40
P = 102.83...cm^2
P = 102.8cm^2 ( to the nearest tenth )
FINAL ANSWER:
Therefore, the perimeter of the window is 102.8cm^2 ( to the nearest tenth ).
Hope this helps! :)
Have a lovely day! <3
•sum of the angles in a triangle = 180°
•sum of the angle in a quadrilateral = 360°
•opposite angles are equal
•for two parallel lines and a transversal, corresponding angles are equal, and alternate angles are equal.
•If it already has an angle for a triangle subtract that by 180 and divide it by two you have the other two angle, if you already have two angles on a triangle add those together and subtract from 180 thats the last angle, same for a quadrilateral but you subtract by 360 instead.
The first one? i dont know what else itd be
Answer:
Step-by-step explanation:
this idea is probably a good thing to have a solid understand of. That Cartesian (rect) is the x and y components, of the legs of a triangle and is a way to measure that part of the two leg of the triangle that is made up by those pieces.. while the polar system would measure the hypotenuse of that same triangle with the degrees as a way to place where that hypotenuses goes
the abs value of an imaginary number will give you that distance from the origin to the point.. if you are using that sqrt (
+
) to get the abs. this is the same as the magnitude and can represent a total force. The distance between the origin and the point is that idea of two points.. conveniently we used (0,0) the origin as one of the points.. the other is at the top of the line or the point given by the complex number
Hopefully that helps... :/
