Answer:

f(0) = 5

Step-by-step explanation:

Note that a^{0} = 4

To calculate f(0), substitute x = 0 into f(x), that is

f(0) = 4^{0} + 4 = 1 + 4 = 5

Misha Larkins [42]

Answer:

Not teenagers = 1120

Step-by-step explanation:

Total number of audience members = 1600

30% of the audience were teenagers.

It means 70% of the audience were not teenagers. It can be given by :

x = 70% of 1600

x=\dfrac{70}{100}\times 1600\\\\x=1120

Hence, 1120 audiences were not teenagers.

The boeing 747 airplane is 250 feet in length. If a model of this plane is 8 inches long , what scale was used to create this mo
cluponka [151]

Answer: The wingspan is 36 m.

Using a proportion to solve this, we write the scale factor as a ratio first:  19/38, since 19 is the size of the model's length and 38 is the real length.  For the second ratio, we have 18 for the size of the model wingspan and x for the real wingspan:

19/38 = 18/x

Cross multiply:

19*x = 38*18

19x = 684

How do i solve for this?
Firdavs [7]

9514 1404 393

Answer:

  97.42 square units

Step-by-step explanation:

The area of a sector is given by ...

  A = (1/2)r²θ

where r is the radius (12.2) and θ is the central angle in radians. Here, you're given the central angle as 75°, so you need to convert that to radians.

  75° = (75°)×(π/180°) radians = (5/12)π radians

Then the area is ...

  A = (1/2)(12.2²)(5π/12) = 744.2π/24 ≈ 97.42 . . . square units

__

Equivalently, you can find the area of the circle in the usual way:

  A = πr² = π(12.2²) ≈ 467.59465

Then, multiply by the fraction of the circle that is shaded (75°/360°)

  sector area = (467.59465)(75/360) = 94.42 . . . square units
