Answer:

809.0

Step-by-step explanation:

Given the exponential function h (t) = 1250(0.865)^t

When t = 3

h(3) = 1250(0.865)^3

h(3) = 1250 (0.6472)

h(3) = 809.0

Hence the value to the nearest tenth is 809.0

A population p of migrating butterflies changes over time it is represented by the equation p=100,000*4/5 where w is the number
Trava [24]

Given that,

A population p of migrating butterflies changes over time it is represented by the equation

p=100,000\times (\dfrac{4}{5})^w Where w is number of weeks.

To find,

The population after 2 weeks.

Solution,

We have,

p=100,000\times (\dfrac{4}{5})^w

Put w = 2 in the above equation.

p=100,000\times (\dfrac{4}{5})^2\\\\=100,000\times \dfrac{16}{25}\\\\=64000

So, the population after 2 weeks is 64000 .

Find the area of the shaded region round to the nearest tenth
Alenkinab [10]

Answer: 818.4

Step-by-step explanation:

Using the area of a sector formula, we get the area of the entire sector is (\pi)(27.8^{2})\left(\frac{150}{360} \right).

Using the formula A=\frac{1}{2} ab \sin C, we get the area of the triangle is \frac{1}{2}(27.8)(27.8)(\sin 150^{\circ}).

So, the area of the shaded sector is (\pi)(27.8^{2})\left(\frac{150}{360} \right)-\frac{1}{2}(27.8)(27.8)(\sin 150^{\circ}) \approx \boxed{818.4}

Camille is working in craft class to create new pillows for her room. Each pillow will be made from exactly 36 in2 of material.
Ann [662]

The best design for Camille is the one in which the area matches the total of material she wants to use for each pillow.

<h3>What should Camille consider for her design?</h3>

Camille's main restriction is the material per pillow since she needs every pillow to use only 36 inches of material. Due to this, she needs to make sure the design meets this requirement.

<h3>How to determine how much material each design requires?</h3>

The best method for this is to calculate the area of the design by using the sides. Here are the most common formulas:

  • Triangular design: Base x height/ 2
  • Squared or rectangular design: side x side
  • Circular design: A = π r²

Based on this, the best design is the one that adjusts to the material available.

Note: This question is incomplete because there is no information about the designs; due to this, I answered it based on general knowledge.
