Two quantities a and b have a proportional relationship where a is -4 and b -3 create an equation to represent this relationship

sladkih [1.3K]

Answer:

a = (4/3)b

Step-by-step explanation:

The governing equation here has the form y = kx, where k is the constant of proportionality.

Let's rewrite that as a = kb, and then substitute -4 for a and -3 for b:

-4 = k(-3), or k = 4/3

Then a = (4/3)b

John stands 150 meters from a water tower and sights the top at an angle of elevation of 36º. If John's eyes are 2 meters above

horsena [70]

Answer:

The height of tower $DB=111\ meters$ .

Step-by-step explanation:

Diagram of the given scenario is shown below.

Given that,

Distance between John and tower is $CE=150 \ meters$ .

Angle of elevation to the top of the tower is $\angle DEC=36$ °.

Height of John is $CB=2\ meters$ .

To Find: Height of the tower $DB$ .

So,

In triangle ΔDCE,

$Tan$ (∠ $DEC)= \frac{DC}{CE}$

$Tan (36)= \frac{DC}{150}$

$DC= tan(36)\times 150$

$DC=108.98\ meters$

Now,

To calculate the height of tower we have

$DB=DC+CB$

$DB=108.98+2$

$DB=110.98\ meters$ ≈ $111 \ meters$

Therefore,

The height of tower $DB=111\ meters$ .
