Nataly [62]3 years ago

g(p) \cdot h(p) = p^{4}+2 p^{3}-8 p^{2}-2p+4

Solution:

Given data:

g(p)=(p-2) and h(p)=\left(p^{3}+4 p^{2}-2\right)

To find g(p) \cdot h(p):

g(p) \cdot h(p)= (p-2)\cdot \left(p^{3}+4 p^{2}-2\right)

Distributive property: a(b+c)=ab + ac

               = p\left(p^{3}+4 p^{2}-2\right) -2\left(p^{3}+4 p^{2}-2\right)

               = \left(p^{4}+4 p^{3}-2p\right) +\left(-2p^{3}-8 p^{2}+4\right)

               = p^{4}+4 p^{3}-2p-2p^{3}-8 p^{2}+4

Arrange and add/subtract same powers.

              = p^{4}+(4 p^{3}-2p^{3})-8 p^{2}-2p+4

               = p^{4}+2 p^{3}-8 p^{2}-2p+4

Hence g(p) \cdot h(p) = p^{4}+2 p^{3}-8 p^{2}-2p+4

The cone in the diagram has the same height and base area as the prism. What is the ratio of the volume of the come to the volum
Nimfa-mama [501]

Answer:

\large\boxed{\dfrac{V_{cone}}{V_{prism}}=\dfrac{1}{3}}

Step-by-step explanation:

\text{The formula of a volume of a cone:}\ V_{cone}=\dfrac{1}{3}B_cH_c\\\\B_c-base\ area\ of\ a\ cone\\H_c-height\ of\ a\ cone\\\\\text{The formula of a volume of a prism:}\ V_{prism}=B_pH_p\\\\B_p-base\ area\ of\ a\ prism\\H_p-height\ of\ a\ prism\\\\\text{The cone and the prism have the same base area and height.}\\\text{Therefore}\\\\V_{cone}=\dfrac{1}{3}BH\ \text{and}\ V_{prism}=BH\\\\\text{The ratio of the volume of the cone to the volume of the prism:}

\dfrac{V_{cone}}{V_{prism}}=\dfrac{\frac{1}{3}BH}{BH}=\dfrac{1}{3}

Write the slope intercept form of the equation of each line
lozanna [386]

Answer:

The slope is 1/4 so the slope intercept form is y=1/4+3

Step-by-step explanation:

To find the slope the easiest way from looking at a graph is just to find the rise over run. From looking at the graph we can see that the next point from 0,3 is 4,4. The y here is increased by 1, which means the rise is 1. The x is increased by 4 so the run is 4. From putting rise (1) over run (4) the slope is 1/4. The formula for slope intercept is y=mx+b. m is slope so we substitue that for 1/4 so now we have y=1/4x+b. Then the b is the y intercept, or, at what point the line crosses the y line. Which in this case is 0,3 so the y intercept would be 3 because that is what height it crosses the y line.

What is the difference of the rational expressions below? 2/x-2 - 3/x
VashaNatasha [74]

Answer: \frac{6-x}{x^{2}-2x}

Step-by-step explanation:

Find the least common multiple (LCM) of the denominators. This is:

LCM=x(x-2)

Divide the LCM by each denominator and multiply the result by each numerator, then you obtain:

\frac{2x-3(x-2)}{x(x-2)}

Apply the distributive property, then you obtain:

\frac{2x-3x+6}{x^{2}-2x}

Add like terms, then you obtain:

\frac{6-x}{x^{2}-2x}

Five ninths times the difference of f and 32
Viktor [21]
If we put that into an equation, we get
(5/9)(f/32)
because "five ninths" is a fraction, "times" is multiplication (which can be represented by parenthesis), "the difference" is division, and "the difference of f and 32" is a fraction.

Simplify the following rational expression.
Jet001 [13]

9514 1404 393

Answer:

  (x-8)/(4x-4)  x ≠ 1 or 8

Step-by-step explanation:

Common factors can be cancelled, but cannot be ignored when it comes to determining where the function is undefined.

  \dfrac{x^2-16x+64}{4x^2-36x+32}=\dfrac{(x-8)^2}{4(x-8)(x-1)}=\boxed{\dfrac{x-8}{4x-4}}

The function is undefined for x=1 and x=8, the values of x that make the original denominator zero.
