astra-53 [7]3 years ago
6 0
You know that two variables of an equation are related through direct proportionality when there is a constant value for their ratios. In equation form, a direct proportionality relationship is written as:

y = kx
where k can be any number

<em>Therefore, the answer is B</em>. In this case, k = 15.

Answer:

\LARGE{ \underline{\underline{ \sf{\pink{ Required\: answer:}}}}}

<h2><u>GIVEN</u><u> </u>- </h2>

  • Water tank which is in a shape of right rectangular prism

Dimensions = 6 feet × 4 feet × 7 feet

<h3><u>TO</u><u> </u><u>FIND</u><u> </u><u>-</u><u> </u> </h3>

  • Surface area of tank

<h2><u>SOLUTION</u> - </h2>

<em><u>Using</u></em><em><u> </u></em><em><u>formula</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>surface</u></em><em><u> </u></em><em><u>area</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>right</u></em><em><u> </u></em><em><u>rectangular</u></em><em><u> </u></em><em><u>prism</u></em><em><u> </u></em><em><u>-</u></em><em><u> </u></em>

Surface area =

2(wl  + hl + hw)

L = length

w = width

h = height

( assumimg 6 feet = L , 4 feet = W , 7 feet = h)

Putting value of L, W and H in the equation. we get,

=2(4 × 6 + 7 × 6 + 7× 4)

= 2(24 + 42 + 28)

= 2( 94)

= 2 × 94

= 188

The 3rd term of (a-b)4 is
fgiga [73]

The third term of the expansion is 6a^2b^2

<h3>How to determine the third term of the expansion?</h3>

The binomial term is given as

(a - b)^4

The r-th term of the expansion is calculated using

r-th term = C(n, r - 1) * x^(n - r + 1) * y^(r - 1)

So, we have

3rd term = C(4, 3 - 1) * (a)^(4 - 3 + 1) * (-b)^(3-1)

Evaluate the sum and the difference

3rd term = C(4, 2) * (a)^2 * (-b)^2

Evaluate the exponents

3rd term = C(4, 2) * a^2b^2

Evaluate the combination expression

3rd term = 6 * a^2b^2

Evaluate the product

3rd term = 6a^2b^2

Hence, the third term of the expansion is 6a^2b^2
