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 $DB=111\ meters$ .

Find the average rate of change for f(x) = x2 + 9x + 18 from x = -10 to x = 10.

Ratling [72]

With the way the equation is written, we can assume that the “x2” is x multiplied by 2.

The x2 and 9x are like terms, and can be simplified to 11x.

Our new equation is
f(x) = 11x + 18

With no exponential functions in the equation, the difference of each value’s output would be 11.

Please help with this math question

Sergio039 [100]

Answer:

t = 16/3

Step-by-step explanation:

4/3 : 7= 3t/4 :21

4/3 x 21 = 7 x 3t/4

28 = 21t/4

112 = 21t

t = 112/21 → t = 16/3

Johnny spends half of his weekly paycheck on

Morgarella [4.7K]

Answer:

$ 322

Step-by-step explanation:

x = his paycheck

x - 1/2x + 55 = 216

1/2x + 55 = 216

1/2x = 216 - 55

1/2x = 161

x = 161 * 2

x = $ 322 <===

Find the value of m.

notka56 [123]

Since the 100 degree angle is the same as the m + 20 degree angle, you only have to do: 100-20=80
So the answer is 80
