En una plantación especializada en productos orgánicos, un técnico agrícola tiene dos fertilizantes que contienen diferentes concentraciones de nitrógeno, uno tiene 3% y el otro tiene 11%. ¿Cuántas libras de cada fertilizante debe mezclar para obtener 20 libras con una concentración de 9%?.

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~

the answer is a) y= 2 csc [0.5 (x+pi/2)]-1

step-by-step explanation:

true

step-by-step explanation:

intersecting chords are just lines that intersect. so a line is equal to 180 degrees, so when it is intersected by another chord, then it create supplementary angles, and because the lines cross, vertical angels are also formed.
