How do cnidaria feed,move, and reproduce​

Mathematics
1 answer:
Nady [450]3 years ago
8 0

Answer:

Cnidarians do not have true organs, however. Reproduction is by asexual budding (polyps) or sexual formation of gametes (medusae, some polyps). The result of sexual reproduction is a larva, which can swim on its own.

Solve the equation. 2/3 - 4x 7/2= -9x+ 5/6 step by step
Lostsunrise [7]

Answer:  \bold{x=\dfrac{11}{21}}

<u>Step-by-step explanation:</u>

\dfrac{2}{3}-\dfrac{4x+7}{2}=-9x+\dfrac{5}{6}\\\\(6)\dfrac{2}{3}-(6)\dfrac{4x+7}{2}=-9x(6)+(6)\dfrac{5}{6}\qquad \text{(multiplied by LCD) }\\\\4 - 12x-21=-54x+5\qquad \text{(simplified)}\\\\-12x - 17 = -54x + 5\qquad \text{(added like terms)}\\\\42x-17=5\qquad \text{(added 54x to both sides)}\\\\42x = 22\qquad \text{(added 17 to both sides)}\\\\x=\dfrac{22}{42}\qquad \text{(divided both sides by 42)}\\\\x=\dfrac{11}{21}\qquad \text{(reduced the fraction)}


NOTE: The sign between 4x and 7 is missing in the question you posted.  I assumed it was 4x + 7 in order to solve the equation.

Anyone able to help with this question?
ELEN [110]

Answer:

This is trigonomentry

Use SOHCAHTOA

where :

s is sin

c is cos

t is tan

o is opposite (side)

h is hypotenuse (opposite of 90 degree angle)

and a is adjacent (side)

Sin = o/h

cos = a/h

tan = o/a

in this case we are looking for side BC which is the hypotenuse(h)

and we have the side adjacent(a) to angle 71

since we have a and h determine what to use SIN, COS, OR TAN?

we should use Cos

they‘ve given the angle so we should do this...

Cos71 = \frac{6.3}{h}

Cos71 = \frac{6.3}{BC}

now apply algebra...

6.3/cos71= BC

BC= 19.3507869666

BC = 19.4   (3SF)
