Which polynomial function has a leading coefficient of 1 and roots 2i and 3i with multiplicity 1? f(x) = (x – 2i)(x – 3i) f(x) =
kykrilka [37]

Answer:

P(x)=(x-2i)(x-3i)

Step-by-step explanation:

Build a Polynomial Knowing its Roots

If we know a polynomial has roots x1, x2, ..., xn, then it can be expressed as:

P(x)=a(x-x1)(x-x2)...(x-xn)

Where a is the leading coefficient.

Note the roots appear with their signs changed in the polynomial.

If the polynomial has a leading coefficient of 1 and roots 2i and 3i with multiplicity 1, then:

P(x)=1(x-2i)(x-3i)

\mathbf{P(x)=(x-2i)(x-3i)}

A water tank is built in the form of a right rectangular prism, with dimensions that measure 13.4 ft by 8.7 ft by 7.5 ft. How ma
Alex17521 [72]

The volume of water that the rectangular prism will hold when it is full is: 874.35 ft³.

<h3>What is the Volume of Rectangular Prism?</h3>

Volume = length × width × height

Given:

  • Length = 13.4 ft
  • Width = 8.7 ft
  • Height = 7.5 ft

Thus:

Volume of water = 13.4 × 8.7 × 7.5

Volume of water = 874.35 ft³

Thus, the volume of water that the rectangular prism will hold when it is full is: 874.35 ft³.

Tell whether the lines for each pair of equations are parallel, perpendicular, or neither
stiks02 [169]

Answer:

C)  Neither

Step-by-step explanation:

y = -1/4x + 8

-2x + 8y = 4

To compare the slopes  we need to convert the second equation to the same form as the first ( that is slope/intercept form).

-2x + 8y = 4

8y = 2x + 4

Divide through by 8:-

y = 1/4 x + 1/2

The slope of the first line is -1/4 and its  1/4 for the second line.

If the slopes were the same the lines would be parallel and if they were perpendicular  their product would be = -1.

The product is 1/4 * -1/4 = -1/16

So they are neither parallel nor perpendicular.

If the line through (-2,4) and (5,d) is parallel to the graph of y=3x+4, what is the value of d?
zhannawk [14.2K]
Y = 3x + 4....slope here is 3. A parallel line will have the same slope.

slope = (d - 4) / (5 - (-2) = (d - 4) / (5 + 2) = (d - 4) / 7....so d is going to have to be 25.

lets check....the slope has to equal 3 to be a parallel line
(-2,4)(5,25)
slope = (25 - 4) / (5 - (-2) = 21/(5 + 2) = 21/7 = 3 (correct)

so d = 25
