It’s a red blood cell it carries blood around the body and does not have a nucleus because it won’t have enough room for the blood .it also carries oxygen

Z - 1,092.8 = 1,200 A. z = 2,292.8 B. z= 2,193.8 C. z= 2,291.2

OleMash [197]

Answer:

A. z = 2292.8 is your answer

Step-by-step explanation:

Isolate the variable (z). Note the equal sign, what you do to one side, you do to the other. Add 1092.8 to both sides

z - 1092.8 (+1092.8) = 1200 (+1092.8)

z = 1200 + 1092.8

z = 2292.8

A. z = 2292.8 is your answer

Please show me how to solve the initial value problem y'=tanx y(pi/4)=3

AlexFokin [52]

The ODE is separable, i.e. you can write

$\dfrac{\mathrm dy}{\mathrm dx}=\tan x\iff\mathrm dy=\tan x\,\mathrm dx$

Integrating both sides gives the general solution.

$\displaystyle\int\mathrm dy=\int\tan x\,\mathrm dx$
$y=-\ln|\cos x|+C$

Given that $y\left(\dfrac\pi4\right)=3$ , we have

$3=-\ln\left|\cos\dfrac\pi4\right|+C$
$3=-\ln\dfrac1{\sqrt2}+C$
$3-\ln\sqrt2=C$

and so the particular solution to the IVP is

$y=-\ln|\cos x|+3-\ln\sqrt2$
$y=3-\ln|\sqrt2\cos x|$
