The graph of y = -5x + 1

Mathematics
1 answer:
Colt1911 [192]3 years ago
6 0

y = -5x + 1

[y = mx + b     "m" is the slope, "b" is the y-intercept (the y value when x = 0)]

So your slope is -5, and your y-intercept is 1 or (0,1)


Slope = \frac{rise}{run}

Rise is the number of units you go up(+) or down(-).

Run is the number of units you go to the right.


Since your slope is -5 or \frac{-5}{1}, you go down 5 units, and to the right 1 unit.

If all the dimensions of the rectangular pyramid are multiplied by 1/5, what is the effect on the volume
Pachacha [2.7K]

Answer:

If all the dimensions of the rectangular pyramid are multiplied by 1/5, the volume will be 125 times smaller.

Step-by-step explanation:

A rectangular pyramid has the following dimensions:

length(l), height(h) and width(w)

The volume is:

V = \frac{l*h*w}{3}

If all the dimensions of the rectangular pyramid are multiplied by 1/5

Then we have that:

l = \frac{l}{5}, w = \frac{w}{5}, h = \frac{h}{5}

The modified volume will be:

V_{M} = \frac{\frac{l}{5}*\frac{w}{5}*\frac{h}{5}}{3} = \frac{\frac{l*w*h}{125}}{3} = \frac{l*h*w}{125*3} = \frac{1}{125}(\frac{l*h*w}{3}) = \frac{V}{125}

So

If all the dimensions of the rectangular pyramid are multiplied by 1/5, the volume will be 1/125 of the original, that is, 125 times smaller.

Evaluate each function for the given value
Mariulka [41]

Answer:

3)  5

5)  1

Step-by-step explanation:

substitute the value of 9 for each 'x' in the expression

3) h(9) = 2/3(9) - 1

            = 18/3 - 1

            = 6-1 or 5

substitute the value of 5 for each 'x' in the expression

5) f(5) = -5² + 6(5) - 4

         = -25 + 30 - 4

         = 5-4 or 1

Identify the surface whose equation is given. rho2(sin2(φ) sin2(θ) + cos2(φ)) = 49
Paha777 [63]

Answer:

The surface is a cylindrical surface with radius 7 units

Step-by-step explanation:

The equation is properly written as:

\rho^{2} (sin^{2} \phi sin^{2} \theta + cos^{2} \phi) = 49

The above equation takes the form y^{2} + z^{2} = r^{2}

Where y^{2} = \rho^{2} sin^{2} \phi sin^{2} \theta

y = \rho sin \phi sin \theta

and z^{2} = \rho^{2}cos^{2}  \phi

z = \rho cos \phi

r^{2} = 49

r = 7 units

The surface is a cylindrical surface with radius 7 units
