Answer:

v is negative for every x, meaning the domain is all values in R, whatever goes under the squared sign will come out as positive and the left out -ve sign will make V negative for all x in R

range of f(x) is -inf to +inf

Jules reads that 1 pint is equivalent to 0.473 liters. He asks his teacher how many liters there are in a pint. His teacher resp
andrey2020 [161]

One pint is equivalent to 0.473 liters which is approximately 0.47 liters if rounding off nearest to hundredth decimal places and 0.5 liters if rounding off nearest to tenth places.

Further explanation:

Jules reads that one pint is equivalent to 0.473 liters.

1\,\,{\text{Pint}}=0.473\,\,{\text{liters}}

But according to his teacher, one pint is about 0.47 liters.

1\,\,{\text{Pint}}\approx0.47\,\,{\text{liters}}

His teacher round off a value of one pint in liters nearest to hundredth places.

Also according to his parents, one pint is about 0.5 liters.

1\,\,{\text{Pint}}\approx0.5\,\,{\text{liters}}

His parents round off the value of one pint in liters nearest to tenth place.

Therefore, his parents and teachers are both right approximately.

Thus, one pint is equivalent to 0.473 liters which is approximately 0.47 liters if rounding off nearest to hundredth decimal places and 0.5 liters if rounding off nearest to tenth places.

Write the expression in algebraic form. [hint: sketch a right triangle.] tan(arcsec(x/3))
WARRIOR [948]

Sketch  a right triangle having adjacent side(A) is given as “3”, hypotenuse side (H) is “x” and assigning angle “a” as the angle between A and H. Using Pythagorean theorem, you will get “square root of x-squared minus 9” as the opposite side (O). Using SOH CAH TOA function, and since secant is the reciprocal of cosine, sec(a) = x/3. Thus, a = arcsec(x/3). The remaining expression tan(a) is Opposite side over Adjacent side which is equal to “square root of x^2 - 9” over "3". Therefore, the algebraic expression would be: tan(arcsec(x/3)) = “sqrt (x^2 -9)” /3. Different answers can be made depending on which side you consider the “3” and “x”.

Jim and his dad are building a rectangular flower bed. They have a total of 35 feet of landscaping timber to use, and they want
Mama L [17]
The perimeter is 35.  If we were to change the width, which is one of the dimensions of the flower bed, The perimeter will change.  This means that perimeter will no longer be 35.  So in order to keep the perimeter as it is, if we change one dimension, we must also change the other. Let's solve for the length, using the formula to see how much the length changes from. p = 2l + 2w 35 = 2l + 2(15) 35 = 2l + 30 5 = 2l 2.5 = l  We must increase the length from 2.5 feet.  This is because decreasing one dimension will decrease the perimeter.  But if we increase the other dimension as well, it will restore the perimeter to where is was initially.

Sophia used the Order of Operations to simplify 4(5 - 2) to 4x3.
Alchen [17]

Answer:

  • Yes

Step-by-step explanation:

<u>Order of operations, use the operation within the parenthesis:</u>

  • 1) 5 - 2 = 3
  • 2) 4*3 = 12

<u>Distributive property, a(b + c) = ab + ac:</u>

  • 1) 4*5 - 4*2 = 20 - 8
  • 2) 20 - 8 = 12

Both ways are correct and lead to same result
