Answer:

Step-by-step explanation:

As the options are not given in the question, lets find the amount spend in next 6 years and make a graph of it. I hope it helps

For year = 0:

Total spending = $12 billion

For year = 1:

Total spending is decreased by 30% as compared to year = 0

Find 30%:

\frac{30}{100}\cdot12=3.6

Total spending = 12 - 3.6 = $8.4 billion

For year = 2:

Total spending is decreased by 30% as compared to year = 1

Find 30%:

\frac{30}{100}\cdot8.4=2.5

Total spending = 8.4 - 2.5 = $5.9 billion

For year = 3:

Total spending is decreased by 30% as compared to year = 2

Find 30%:

\frac{30}{100}\cdot5.9=1.77

Total spending = 5.9 - 1.77 = $4.13 billion

For year = 4:

Total spending is decreased by 30% as compared to year = 3

Find 30%:

\frac{30}{100}\cdot4.13=1.24

Total spending = 4.13 - 1.24 = $2.89 billion

For year = 5:

Total spending is decreased by 30% as compared to year = 4

Find 30%:

\frac{30}{100}\cdot2.89=0.87

Total spending = 2.89 - 0.87 = $2.02 billion

For year = 6:

Total spending is decreased by 30% as compared to year = 5

Find 30%:

\frac{30}{100}\cdot2.02= 0.6

Total spending = 2.02 - 0.60 = $1.42 billion

<h3>Graph:</h3>

x-axis = no. of year

y-axis = Total spending

Join the point to get the desired graph (see the picture)

A running circuit is in the shape of a triangle with lengths of 6km, 6.5km and 7km. What are the sizes of the angles (in minutes
Rudik [331]

A <u>triangle</u> is an example of a class of <em>figures</em> referred to as <em>plane shapes</em>. It has <u>three</u> straight <u>sides</u> and <u>three</u> internal <u>angles</u> which sum up to 180^{o}. The <em>measures</em> of the internal <u>angles</u> of the <u>triangle</u> given in the question are A = 52.6^{o}, B = 59.4^{o}, and C = 68^{o}.

A <u>triangle</u> is an example of a class of <em>figures</em> referred to as <em>plane shapes</em>. It has <u>three</u> straight <u>sides</u> and <u>three</u> internal <u>angles</u> which sum up to 180^{o}.

Considering the given question, let the <u>sides</u> of the triangle be: a = 6 km, b = 6.5 km, and c = 7 km.

Apply the <em>Cosine rule</em> to have:

c^{2} = a^{2} + b^{2} - 2ab Cos C

So that;

7^{2} = 6^{2} + (6.5)^{2} - 2(6 * 6.5) Cos C

49 = 36 + 42.25 - 78Cos C

78 Cos C = 78.25 - 49

               = 29.25

Cos C = \frac{29.25}{78}

         = 0.375

C = Cos^{-1} 0.375

   = 67.9757

C = 68^{o}

Apply the <em>Sine rule</em> to determine the <u>value</u> of B,

\frac{b}{Sin B} = \frac{c}{Sin C}

\frac{6.5}{Sin B} = \frac{7}{Sin 68}

SIn B = \frac{6.5 *Sin 68}{7}

         = 0.861

B = Sin^{-1} 0.861

   = 59.43

B = 59.4^{o}

Thus to determine the value of A, we have;

A + B + C = 180^{o}

A + 59.4^{o} + 68^{o} = 180^{o}

A = 180^{o} - 127.4

  = 52.6

A = 52.6^{o}

Therefore the <u>sizes</u> of the <em>internal angles</em> of the triangle are: A = 52.6^{o}, B = 59.4^{o}, and C = 68^{o}.
