Answer:

  • B. sine

Step-by-step explanation:

In the given case you would use sine

  • sin  = opposite / hypotenuse
  • sin 47 = y/11
  • y = 11 sin 47
  • y = 8.0 (rounded)

Using cosine or tangent you wouldn't be able to find the value of y as the value of x is unknown

GIVEN:

p = y, b = x, h = 11, angle = 47°.

ANSWER:

We will use sin function to find the value of y,

so, sin47° = p/h

sin47° = y/11

y = sin47° × 11

y = 0.73135370 × 11

y = 8.03 or 8.0 rounded.

So, <u>Correct choice</u> - [B] Sine.

Angles 1 and 2 are complementary, and angle 1=3x+3 and angle 2=10x-4, find the degree measure of each angle
tensa zangetsu [6.8K]

Answer:

The measure of the angles:

24°  and   66°

Step-by-step explanation:

Complementary angles sum 90°

then:

(3x + 3) + (10x-4) = 90

3x + 10x + 3 - 4 = 90

13x - 1 = 90

13x = 90+1

13x = 91

x = 91/13

x = 7°

then:

  • angle 1:

3x+3 = 3*7 + 3 = 21+3 = 24°

  • angle 2

10x - 4 = 10*7  - 4 = 70 - 4 = 66°

Check:

66° + 24° = 90°

Professor Vinculum investigated the migration season of the Bulbul bird from their natural wetlands to a warmer climate. He foun
coldgirl [10]

The population of the Bulbul birds at the start of the migration season is 1800.

<h3>Exponential function</h3>

An exponential function is given by:

y = abˣ

Let y, x are variables, a is the initial value and b is the multiplication factor.

Let P be the population of the bird t days since the start of the migration season.

P=1350+400(1.25)^{-t}\\\\At\ the\ start\ of\ the\ season(t=0):\\\\P=1350+400(1.25)^{-0}\\\\P=1350+450=1800

The population of the Bulbul birds at the start of the migration season is 1800.
