The answer is D (- 4x^2 - 3x - 5)

Explanation:

- 4f(x) - 3g(x)
= - 4(x^2 + 5) - 3(x - 5)
= - 4x^2 - 20 - 3x + 15
= - 4x^2 - 3x - 5

Rampur Sarpanch requested one of his villager to donate a 6m wide land adjusted to his 132.8m long side of his right triangular
Furkat [3]

Answer:

The answer is 3030.72 m³

Step-by-step explanation:

Please refer to attached file for graphical representation.

Formulas used:

Area = (a*b)/2

Trigonometry: Tan (t) = opposite/adjacent

Assume:

Villager plot has 3 sides: hypotenuse=C, adjacent=A, opposite=B

Plot given has 3 sides: hypotenuse=z, adjacent=y, opposite=x

Angle common between them is t.

<u>Step 1</u>:

For t:

Tan (t) = a/b

Tan (t) = 123/50

Tan (t) = 2.46

<u>Step 2:</u>

For y:

Tan (t) = y/x

2.46 = y/6

y = 2.46*6

y = 14.76

<u>Step 3:</u>

Villagers old plot area: B = (a*b)/2 = (123*50)/2

B = 3075 m³

<u>Step 4:</u>

Plot donated area: C = (x*y)/2 = (6*14.76)/2

C = 44.28 m³

<u>Step 5:</u>

Villager remaining plot:

A = B-C

A= 3075-44.28

A = 3030.72 m³

16n2 – 10n – 5 = 6n<br> Solve the equation for all real solutions
sergiy2304 [10]

Answer:

n=5/4 or n=-1/4

Step-by-step explanation:

16n^2 - 10n-5=6n

16n^2-16n-5=0

(4n)^2-2.4n.2+2^2 = 2^2 + 5

(4n- 2)^2=9

4n-2 = 3 or 4n-2=-3

4n=5 or 4n=-1

n=5/4 or n = - 1/4
