Cosines someone please help me. Include an explanation and a clear answer
Readme [11.4K]

The formula for the law of cosines is:

a^2 = b^2 + c^2 - 2*b*c*cos(angle)

In this triangle b = 7, c = 8 and angle = 32.

a^2 = 7^2 + 8^2 - 2*7*8*cos(32)

a^2 = 18.018

a = SQRT(18.018)

a = 4.24

C = 4.2 feet.

melamori03 [73]

a) If this trend continues, how many birds will be left by 2010 will be 525

b) The  birds would there have been in 1990 will be 2475

<h3>What is rate of increase?</h3>

Rate of increase or decrease is defined as the increment or decrement in any quantity over a period of time constantly.

Here we have the data that:

There were 1500 birds in 2000 and they are decreasing at an annual rate of 6.5%.

a) If this trend continues, how many birds will be left by 2010

{1500x6.25}/{100}=97.5

So the bird decrement in the one year will be =97.5 so it will be in the 10 years or upto 2010 will be

97.5x10=975

So the birds left till 2010 will be:

Q=1500-975=525

b)The birds would there have been in 1990 will be:-

=1500+975=2475

Hence If this trend continues, how many birds will be left by 2010 will be 525.The  birds would there have been in 1990 will be 2475

Answer:

d = \frac{1}{4}

Step-by-step explanation:

Given

= 16(d + 1) = - 20 ← distribute parenthesis on left side

- 16d - 16 = - 20 ( add 16 to both sides )

- 16d = - 4 ( divide both sides by - 16 )

d = \frac{-4}{-16} = \frac{1}{4}
