Zofia's dermatologist has recommended a drug called Accutane for her acne. Accutane has potentially serious detrimental effects on a fetus, so Zofia is required to have a pregnancy test both before she begins treatment and every month that she takes the medication. In this situation, Accutane would act as a/an _____ on an unborn child.A) proximodistal
B) teratogen
C) cephalocaudal
D) androgen

Answers

Answer 1

Answer: Accutane would act as a B. TERATOGEN on an unborn child.

Because Accutane has a potentially serious detrimental effect on a fetus, it acts as a teratogen on an unborn child. This means that if the drug is taken while pregnant, it will serve as an agent that causes the malformation of an embryo.

Determine which functions have two real number zeros by calculating the discriminant, b2 – 4ac. Check all that apply. Please answerf(x) = x2 + 6x + 8
g(x) = x2 + 4x + 8
h(x) = x2 – 12x + 32
k(x) = x2 + 4x – 1
p(x) = 5x2 + 5x + 4
t(x) = x2 – 2x – 15

Answers

By definition, we have that the discribinamte is given by:
$b ^ 2 - 4ac$
If the discriminant is greater than zero, then the function has two real roots.
We then have to calculate the discriminant for each function:

For $f (x) = x ^ 2 + 6x + 8:$
$b ^ 2 - 4ac = 6 ^ 2 - 4 (1) (8) b ^ 2 - 4ac = 36 - 32 b ^ 2 - 4ac = 4$
The function has two real roots.

For $g (x) = x ^ 2 + 4x + 8$
$b ^ 2 - 4ac = 4 ^ 2 - 4 (1) (8) b ^ 2 - 4ac = 16 - 32 b ^ 2 - 4ac = -16$
The function does not have two real roots.

For $h (x) = x ^ 2 - 12x + 32$
$b ^ 2 - 4ac = (-12) ^ 2 - 4 (1) (32) b ^ 2 - 4ac = 144 - 128 b ^ 2 - 4ac = 16$
The function has two real roots.

For $k (x) = x ^ 2 + 4x - 1$ :
$b ^ 2 - 4ac = (4) ^ 2 - 4 (1) (- 1) b ^ 2 - 4ac = 16 + 4 b ^ 2 - 4ac = 20$
The function has two real roots.

For $p (x) = 5x2 + 5x + 4$ :
$b ^ 2 - 4ac = (5) ^ 2 - 4 (5) (4) b ^ 2 - 4ac = 25 - 80 b ^ 2 - 4ac = -55$
The function does not have two real roots.

For $t (x) = x ^ 2 - 2x - 15$ :
$b ^ 2 - 4ac = (-2) ^ 2 - 4 (1) (- 15) b ^ 2 - 4ac = 4 + 60 b ^ 2 - 4ac = 64$
The function has two real roots.

Answer:
functions have two real number zeros
$f (x) = x ^ 2 + 6x + 8 h (x) = x ^ 2 - 12x + 32 k (x) = x ^ 2 + 4x - 1 t (x) = x ^ 2 - 2x - 15$

f(x) = x^2 + 6x + 8
= b^2 - 4ac
= (6)^2 - 4(1)(8)
= 36 - 4(8)
= 36 - 32
= 4

g(x) = x2 + 4x + 8
= b^2 - 4ac
= (4)^2 - 4(1)(8)
= 16 - 4(8)
= 16 - 32
= -16

h(x) = x2 – 12x + 32
= b^2 - 4ac
= (-12)^2 - 4(1)(32)
= 144 - 4(32)
= 144 - 128
= 16

k(x) = x2 + 4x – 1

= (4)^2 - 4(1)(-1)
= 16 - 4(-1)
= 16 + 4
= 20

p(x) = 5x2 + 5x + 4
= b^2 - 4ac
= (5)^2 - 4(5)(4)
= 25 - 4(20)
= 25 - 80
= -55

t(x) = x2 – 2x – 15
= b^2 - 4ac
= (-2)^2 - 4(1)(-15)
= 4 - 4(-15)
= 4 + 60
= 64

Which method is contrary to the principles of Martin Luther King, Jr.?a. sit-ins at a segregated restaurant

c. demonstrations by minorities in front of a government building
d. marches on Washington to draw attention to the needs of minorities

Answers

b, use of violence to express frustration in achieving racial equality

Use of violence to express frustration in achieving racial equality is a contrary to the principles of Martin Luther King, Jr.

So, that would make (B. use of violence to express frustration in achieving racial equality.) your answer.

A thunderstorm loses energy in the _______ stage.A. mature
B. dissipation
C. cumulus
D. frontal

Answers

The word that completes the statement "A thunderstorm loses energy in the _______ stage." is dissipation. After around 30 minutes, the thunderstorm starts to disperse. This happens when the downdrafts in the cloud start to command over the updraft. Since warm wet air can not rise anymore, cloud beads can not frame anymore.

B.dissipation . hope i helped.
