4) Solve ∆ABC, a = 2.5 cm, c = 3.6 cm, and ∠A = 43°. Begin by sketching and labelling
mezya [45]

The length of b and angle B and C are 3cm, 45  degrees and 79 degrees respectively.

<h3>How to determine the parameters</h3>

To determine the angles and length of sides, we use the sine rule

The sine rule is thus:

\frac{sin A}{a} = \frac{sin B}{b} = \frac{sin C}{c}

Given;

  • a = 2. 5cm
  • c = 3. 6cm
  • ∠A = 43°

Let's find angle C

\frac{sin 43}{2. 5} = \frac{sin C}{3. 6}

cross multiply

0. 682 × 3. 6 = sin C × 2. 5

sin C = 2. 4552/ 2. 5

C = sin^-^1(0. 982)

C = 79°

To find length of b

b= \sqrt{c^2 - a^2}

substitute the values

b = \sqrt{3.6^2 - 2. 5^2}

b = \sqrt{6. 71}

b = 2. 59 cm

b = 3cm

To find angle B, we have

\frac{sin 43}{2. 5} = \frac{sin B}{2. 59}

cross multiply

0. 682 × 2. 59= sin B × 2. 5

sin B = 0. 7065

B = sin^-^1(0. 7065)

B = 45°

Hence, the length of b and angle B and C are 3cm, 45  degrees and 79 degrees respectively.

A firm’s production function is
Nastasia [14]

The value of MPL for the various cases are;

<em><u>A) MPL = 49.98</u></em>

<em><u>B) MPL = 49.8</u></em>

<em><u>C) MPL = 48</u></em>

<em><u>D) MPL = 30</u></em>

We are given;

Q = 50L - 0.01L²

Now MPL means marginal product of labor and it is defined as the derivative of Q with respect to L. Thus;

MPL = dQ/dL = 50 - 2(0.01L)

A) When L = 1;

MPL = 50 - 2(0.01 × 1)

MPL = 49.98

B) When L = 10;

MPL = 50 - 2(0.01 × 10)

MPL = 49.8

C) When L = 100

MPL = 50 - 2(0.01 × 100)

MPL = 48

D) When L = 1000

MPL = 50 - 2(0.01 × 1000)

MPL = 30

Answer:

"Element of a Set"

Step-by-step explanation:

For example, the statement x∈A means that x is an element of the set A. In other words, x is one of the objects in the collection of (possibly many) objects in the set A.

Robby has 6 orange juice containers. Each on gallon container is 2/3 full. Sophie says he only needs 4 containers to carry all o
Stolb23 [73]
To determine of 4 containers are all that are needed, you will find the total number of gallons that are in the 6 containers by multiplying the 2/3 gallon in each container by 6.

2/3 x 6 gallons = 4 gallons.

You would be able to put all the orange juice in 4 containers.
