Find the value of W if A=LW, A=8m^2, and L=4m

PLEASE HELP

Answers

Answer 1
Answer: A=LW\ \ \ \ |divide\ both\ sides\ by\ L\n\nW=(A)/(L)\n===============\n\nA=8m^2;\ L=4m\n\nW=(8m^2)/(4m)=2m^(2-1)=2m


A=lW    divide both sides by L

W=A / L
----------------------------------------------------------------------
A=8m^2; L=4m

W=(8m^2) / (4m) = 8 / 4 * m^2 / m =2m
Answer 2
Answer: A=8 \ m^2, \ \ L=4 \ m \n\n A=LW\n\n8 \ [m^2]= 4 \ [m ]\cdot W \ \ / :(4 \ [m]) \n \nW=(8 )/(4) \cdot ([m^(2)])/([m])= 2 \ m \n \n\nAnswer : \ W =2 \ m

For a wall of a given material and of a fixed surface area, the rate of heat loss by conduction through the wall is inversely proportional to the thickness (T) of the wall, and directly proportional to the temperature difference (d) across the wall. The rate of heat loss could be given by which of the following expressions?A. 2d/T
B. 2 T/d
C. 2d + ½ T
D. 2(d + ½ T)
E. T/d

Answers

the answer is        A .2d/T
Since d is directly proportional to the heat lost it should be the numerator
since T is inversely proportional to the heat lost it shoudl be the denormirator
 that is      1/T ;         2 is the constant
the actual formula is        R = kd/T

The zeros of the function f(x)=(x+2)^2 - 25 are?

Answers

Zeros of the function
f(x) = (x + 2)² - 25
f(x) = (x + 2)(x + 2) - 25
f(x) = x(x + 2) + 2(x + 2) - 25
f(x) = x(x) + x(2) + 2(x) + 2(2) - 25
f(x) = x² + 2x + 2x + 4 - 25
f(x) = x² + 4x + 4 - 25
f(x) = x² + 4x - 21
x² + 4x - 21 = 0
x = -(4) +/- √((4)² - 4(1)(-21))
                      2(1)
x = -4 +/- √(16 + 84)
                   2
x = -4 +/- √(100)
               2
x = -4 +/- 10
            2
x = -2 + 5
x = -2 + 5    x = -2 - 5
x = 3           x = -7
f(x) = x² + 4x - 21
f(3) = (3)² + 4(3) - 21
f(3) = 9 + 12 - 21
f(3) = 21 - 21
f(3) = 0
(x, f(x)) = (3, 0)
or
f(x) = x² + 4x - 21
f(-7) = (-7)² + 4(-7) - 21
f(-7) = 49 - 28 - 21
f(-7) = 21 - 21
f(-7) = 0
(x, f(x)) = (-7, 0)

Vertex
X - Intercept
-b/2a = -(4)/2(1) = -4/2 = -2

Y - Intercept
y = x² + 4x - 21
y = (-2)² + 4(-2) - 21
y = 4 - 8 - 21
y = -4 - 21
y = -25
(x, y) = (-2, -25)
y=x^2+4x+4-25
y=x^2+4x-21
y=(x+7)(x-3)
zeros are -7 and 3

90. The pharmaceutical abbreviation "bid" means _____________________. a. once a day b. twice a day c. once a week d. twice a week

Answers

Answer:

The pharmaceutical abbreviation "bid" means "twice a day." In medical terminology, "bid" stands for "bis in die," which is Latin for "twice a day." It indicates that a medication should be taken two times within a 24-hour period, typically with an interval of approximately 12 hours between doses.

Step-by-step explanation:

Understanding pharmaceutical abbreviations is crucial for proper medication administration and adherence to prescribed dosing schedules. In this case, knowing that "bid" means "twice a day" helps ensure that patients take their medication as directed by their healthcare provider.

Select the correct answer from the choices given(13 + 4i) + n = 0
What is n?

a. 0

b. 1

c. –13 + 4i

d. –13 - 4i

Answers

In equating a complex number to 0, we must add an opposite form of the equation, where the values of the real and imaginary parts are the same as the original, but have opposing signs. In the case of (13 + 4i), we have to add (-13 - 4i) to equate it to 0. Among the choices, the correct answer is D.

Answer:

d -13-4i
