It is C. The first part is raised to the 2nd power. so it goes first since that is the highest. then the -20x because variables are understood to the power of 1, while normal numbers are understood to the power of 0. so the order is highest to lowest (2,1,0)

5x^2 - 20x = 15

Divide both sides by 5, it would give :

x^2-4x=3

After it gives : 

x^2-4x-3=0

So the answer would be : B.

Hope this helps !

Which equation could be used to find the perimeter of a rectangle that has a width of 12 cm and a length of 16 cm?
Vsevolod [243]
It would be a. because a rectangle has 2 pairs of congruent sides so since the width is 12 and there are 2 sides with that measurement it would be 2(12) and the same goes for the length, and then you add them together.

X^6 + y^6 = 1<br><br> What does:<br> y'' =
madreJ [45]
Before taking the derivatives of the function, simplify the equation first for smooth operation.

x^6 + y^6 = 1

Multiply the whole equation with an exponent of 1/6 for uniformity. This would get rid of the exponents of x and y. The product would be

x + y = 1^1/6
x + y = 1

Expressing in terms of x:

y = 1 - x

Now, we derive the equation:

y' = 0 -1 = -1
y" = 0

By rounding to 1 significant figure , estimate <br><br> 40.73 x 1.06<br><br> Anyone know?
suter [353]

ANSWER: 40

EXPLANATION:

1) 40.73 to 1 significant figure = 40.

2) 1.06 to 1 significant figure = 1.

3) Therefore, we just multiply 40 by 1, which equals 40.

FURTHER EXPLANATION (IF NEEDED):

With significant figures, whole numbers such as 10, 20, 50 etc. have 1 significant figure. This is because the 0 does not count as a significant figure.

With decimals, all numbers after the decimal point are also included as significant figures (even 0). E.g. 40.73 has 4 significant figures and 1.06 has 3 significant figures.

EXAMPLES (IF NEEDED):

Rounding to 2 significant figures:

  • 40.73 = 42
  • 1.06 = 1.1

Rounding to 3 significant figures:

  • 40.73 = 40.7
  • 1.06 = 1.06 (because it's already in 3 significant figures)

Rounding to 4 significant figures:

  • 40.73 = 40.73 (already in 4 significant figures)
  • 1.06 = 1.060 (0 is counted as a significant figure if there is a decimal or another number comes after that 0)

E.g. 1006 has 4 sig figs, while 1060 would have 3 sig figs because the last 0 is not counted as a significant figure. 10.60 would have 4 sig figs because of the decimal.

A cruise ship is traveling at a speed of 20 knots. A knot is aproxamatley equal to 1.151 miles per hour what is the approximate
algol13

20 knots * 1.151 = 23.02 miles per hour  There are 1,760 yards in a mile and 3,600 seconds in an hour.  So, we multiply 23.02 * (1,760 / 3,600) which equals

11.2542222222 yards / second
