Which best describes the graph of the function f(x) = -5x ?
il63 [147K]

Answer:

This is a simple slope intercept form equation: y=ax+b

Where a is the slope and b is the y-intercept, but in this problem the y-intercept is 0 so it is no shown.

The line on the graph would be negative (downward) because of the negative and would be going down by a slope of -5.

  -down 5 over 1 ( rise over run )

A cylinder and a cone have the same volume. The cylinder has radius x and height y. The cone has radius 1/3x. Find the height of
slavikrds [6]

Answer:

The height of the cone h = 27(x^4)y

Step-by-step explanation:

Firstly, we calculate the volume of the cylinder.

Mathematically, the volume of the cylinder is pi * r^2 * h

using the radius x and height y

The volume V of the cylinder is ;

V = pi * x^2 * y

Now we know they have the same volume V, the formula for the volume of a cone is ;

1/3 * pi * r^2 * h

Substituting the values of r to be 1/3x and the height which is not given here left as h, we have the volume of the cone to be;

V = 1/3 * pi * (1/3x)^2 * h = pi * x^2 * y

The pi gives way as it cancels out on both sides and we have the following;

h/27x^2 = x^2y

Mathematically h = x^2 * y * 27x^2

h = 27(x^4)y

p.s: I personally feel the radius of the cone was to be given as x/3 and not 1/3x . It is in that way we can have the height of the cone purely in y terms and no x

1. ∠1 ≅ ∠3                                              1. given

  ∠1 and ∠6 are supplementary angles

  ∠3, ∠4, and ∠5 are supplementary angles

2. m∠1 = m∠3                                        2. definition of congruency

3. m∠1 + m∠6 = 180°                             3. definition of supplementary angles

   m∠3 + m∠4 + m∠5 = 180°

4.  m∠3 + m∠4 + m∠5 = m∠1 + m∠6     4. transitive property

5.  m∠3 + m∠4 + m∠5 = m∠3 + m∠6     5. substitution property

6.  m∠4 + m∠5 = m∠6                             6. subtraction property of equality

∠xangle, x and \angle y∠yangle, y are supplementary angles. \angle y∠yangle, y measures 88^\circ88
Yuliya22 [10]

Answer:

92∘

Step-by-step explanation:

Supplementary angles combine to create a straight angle. So, they have a sum of 180.

∠x + ∠y

∠x + 88 -------------->  180

=92∘

Lina is making trail mix for hiking trip she has2 1/2 cups of peanuts, 3 1/4 of raisins and 2 2/3 cups of banana chips how many
Zanzabum

8 5/12 because you have to get the 3 fractions denomenators to be the same. so 3, 4 and 2 all go into 12 then you need go multiply the top by the same number as the bottom
