Let units cancel out just like numbers...

25365.4cm^3(2.7g/cm^3)=68486.58g  which is 68486.6g (to nearest tenth)

(2.7g/cm^3)(25365.4cm)=mass
=68486.58g
or, rounded, 68486.6grams

Algebra 2 help please
Andre45 [30]
(gof)(x) = g(f(x))

so

g(f(x)) = 3(6x - 4)^2 -2(6x - 4) - 10
g(f(x)) = 3(36x^2 - 48x + 16) - 12x + 8 - 10
g(f(x)) = 72x^2 - 144x + 48 - 12x - 2
g(f(x)) = 72x^2 - 156x + 46

answer
(gof)(x) = 72x^2 - 156x + 46

Which is the equation of a line with a slope of -1/3 and a y-intercept at (0,1)?
Nutka1998 [239]

Answer:

The answer is

\huge \boxed{y =  -  \frac{1}{3}x + 1 }

Step-by-step explanation:

To find an equation of a line given the slope and a point we use the formula

y -  y_1 = m(x -  x_1)

where

m is the slope

( x1 , y1) is the point

From the question the point is (0,1) and slope - 1/3

The equation is

y - 1 =  -  \frac{1}{3}(x - 0) \\ y - 1 =  -  \frac{1}{3} x

We have the final answer as

y =  -  \frac{1}{3} x + 1 \\

Hope this helps you

What is the Radius of a circle if a 16 unit chord is 6 units from the center of the circle
velikii [3]

Answer:

radius = 10 units

Step-by-step explanation:

using the Pythagorean theorem:

height of triangle = 6 units

base of triangle = 16/2 = 8 units

radius² = 6² + 8² = 36 + 64 = 100

radius = √100 = 10 units

Please help me anyone I need help with this question ​
Leto [7]

Answer:

  (d)  2x +y = 8

Step-by-step explanation:

The answer choices are shown in "standard form," so the comparison to the given equation is easier if it is written in standard form. Add 2x to both sides:

  2x +y = 5 . . . . . . given equation in standard form

The other equation in a system with no solution will look like this, but will have a different constant:

  2x +y = 8 . . . . . . does not intersect the given equation

_____

<em>Additional comment</em>

All of the other equations shown will intersect the given equation. One way to show this is to use the given equation to substitute for y in the answer choices:

  a: 2x -(-2x+5) = 8   ⇒   6x -5 = 8 . . . one solution: x=13/6

  b: x +2(-2x+5) = 8   ⇒   -3x +10 = 8 . . . one solution: x=2/3

  c: x -2(-2x+5) = 8   ⇒   5x -10 = 8 . . . one solution: x=18/5

  d: 2x +(-2x+5) = 8   ⇒   5 = 8 . . . no solution
