6 0

D. Tanisha is 6, and Bess is 12.

Evidence :
Tanisha has to be HALF of Bess’s age (Support the answer choice D)
Bess is 6 years older than Tanisha.
(Also supports answer choice D)

The rest of the answer choices wouldn’t make sense, as they might only apply to one part of the evidence I put.

find the flux of the constant vector field v→=3i→ 2j→−5k→ through a square plate of area 25 in the xz-plane oriented in the posi

Readme [11.4K]

The flux across a surface is an indicator of the rate at which fluid is flowing through it when there is a fluid flowing in three dimensions and a surface positioned inside that space.

<h3>What is Electric Flux?</h3>

A feature of an electric field is electric flux. One way to conceptualize it is as the quantity of forces interacting in a specific space.
According to conventional wisdom, electric field lines begin with positive electric charges and conclude with negative charges.
A closed surface's field lines are seen as negative when they are directed into it, and as positive when they are directed out of it.
Every field line that is directed into a closed surface continues through the interior and is often directed outward somewhere else on the surface if there is no net charge present within the surface.
The net, or total, electric flux is zero because the size of the negative and positive fluxes are just about equal.
A closed surface that contains a net charge will have a total flux that is proportional to the enclosed charge, positive if it is positive and negative if it is negative.

Dan earns £9.80 per hour how much will I earn for eight hours work

Andrews [41]

Answer:

£78.4

Step-by-step explanation:

Since he earns £9.80 per hour, we multiply this by how many hours there are. So £9.80 times 8 is £78.4. I hope this helps!

The polynomial function y = x3 -3x2 + 16x - 48 has only one non-repeated x-intercept. What do you know about the complex zeros o

earnstyle [38]

• First way to solve:
We'll manipulate the expression of the equation:

$y=x^3-3x^2+16x-48\\\\ y=x^2(x-3)+16(x-3)\\\\ y=(x-3)(x^2+16)$

If we have y=0:

$x-3=0~~~or~~~x^2+16=0\\\\ x=3~~~or~~~x^2=-16\\\\ x=3~~~or~~~x=\pm\sqrt{-16}\\\\ x=3~~~or~~~x=\pm4i$

Then, the function has one real zero (x=3) and two imaginary zeros (4i and -4i).

Answer: B

• Second way to solve:

The degree of the function is 3. So, the function has 3 complex zeros.

Since the coefficients of the function are reals, the imaginary roots are in a even number (a imaginary number and its conjugated)

The function "has only one non-repeated x-intercept", then there is only one real zero.

The number of zeros is 3 and there is 1 real zero. So, there are 2 imaginary zeros.

Answer: B.
