FATHER's age = 50

Step-by-step explanation:

Let age of ELDER son = x

And age of father = 2X

Age of younger son, Y =(x-15)

After 10 years

2x+10=3(x-15+10)

2x+10=3x(x-5)

3x-2x=25

x=25; Y=10; 2x=50

Therfore Father's Age = 50

Answer» ANSWER: k = 7 Step-by-step explanation: F (X) = 3x² - 4X + k f (2)= 3 (2)² - 4(2) + k 11 = 12 - 8 + k therefore k = 7 f (x) = 3x² - 4x + 7

If f'(x)= 3x2-4x+K, f(0)=1 and f(2)=11, them find f(x)

Answer»

ANSWER:

k = 7

Step-by-step explanation:

F (X) = 3x² - 4X + k

f (2)= 3 (2)² - 4(2) + k

11 = 12 - 8 + k

therefore k = 7

f (x) = 3x² - 4x + 7

A steamer goes downstream from one point to another in 7 hours. It covers the same distance upstream in 8 hours. If the speed of stream be 2 km/h, find the speed of the steamer in still water and the distance between the ports.

Answer»

Given:-

A STEAMER goes downstream from one POINT to another in 7 hours. It covers the same DISTANCE upstream in 8 hours. If the speed of stream be 2 km/h.

To Find:-

The speed of the steamer in still water and the distance between the ports.

Solution:-

$\bf \: Let$

The speed of steamer in still water be X km/hr

Speed in downstream = (x+2) km/hr

As we know that

$\begin{gathered} \mapsto \bf \purple{ \boxed{ \bigstar \bf \: Distance = Speed \times Time }} \\ \end{gathered}$

$\begin{gathered} \sf \clubs \: Distance \: covered \: while \: downstream \\ \red{ : \longmapsto \: \bf 7(x + 2) \: km }\\ \\ \clubs \: \sf Distance \: covered \: while \: upstream \\ \red{ : \longmapsto \bf \: 8(x - 2)}\end{gathered}$

ACQ

$\begin{gathered} \therefore \tt 8(x - 2) = 7(x + 2) \\ \tt \twoheadrightarrow8x - 16 = 7x + 14 \\ \tt \twoheadrightarrow8x - 7x = 14 + 16 \\ \tt \twoheadrightarrow \: x = 30\end{gathered}$
