Answer:

320 cm^3 of birdseed

Step-by-step explanation:

To figure this out, you need to find the volume of the whole figure.

To do that, we will need to first find the volume of the rectangular prism, and then the triangular prism.

The volume of the rectangular prism is length x width x height. We plug in  the values:

8 x 5 x 6 =

40 x 6 =

240 cm^3

The volume of the triangular prism is 1/2 x base x height. We plug in the values:

1/2 x (8 x 5) x 4 =

1/2 x 40 x 4 =

20 x 4 =

80 cm^3

Now, we add the volumes:

240 + 80 = 320 cm^3 of birdseed

Answer:

a) Infinite solutions

b) No solutions

Step-by-step explanation:

First, know the following:

If the graphs intersect, there's only one solution.

If the graphs are parallel, there are no solutions.

If the graphs are the exact same line, there are infinite solutions.

For a):

Change the first equation into a linear one.

  • 2x+3y=6
  • 3y=-2x+6
  • y=-\frac{2}{3} x+2

Change the second equation into a linear one.

  • 4x+6y=12
  • 6y=-4x+12
  • y=-\frac{2}{3} x+2

Boom. You have two equations which are equal. As stated above, graphs on the exact same line have infinite solutions.

For b)

They are already in linear form so hurray.

y=\frac{1}{5} x+2\\y=\frac{1}{5} x+10\\

These lines are parallel since they have the SAME slope but a different y-intercept. As stated above, parallel lines have no solutions.

For the function P(x) = x3 − 9x, at the point (2, −10), find the following. (a) the slope of the tangent to the curve (b) the in
Shalnov [3]

Answer:

3, in both a), b)

Step-by-step explanation:

a) The slope of the line tangent to the curve that passes through the point (2,-10) is equal to the derivative of p at x=2.

Using differentiation rules (power rule and sum rule), the derivative of p(x) for any x is p'(x)=3x^2-9. In particular, the value we are looking for is p'(2)=3(2^2)-9=12-9=3.

If you would like to compute the equation of the tangent line, we can use the point-slope equation to get y=3(x-2)-10=3x-16

b) The instantaneus rate of change is also equal to the derivative of P at the point x=2, that is, P'(2). This is equal to p'(2)=3.

Calculate the slope of the line that contains the points: (2,-3) and (6,-3)
pshichka [43]

Answer:

Step-by-step explanation:

Slope (m) =

ΔY

ΔX

= 0

θ =

arctan( ΔY )

ΔX

= 0°

ΔX = 6 – 2 = 4

ΔY = -3 – -3 = 0

Distance (d) = √ΔX2 + ΔY2 = √16 = 4

Equation of the line:

y = 0x – 3

When x=0, y = -3
