First we can label the x in 3x as x sub 1 and the angle we need to find as x sub 2

Then, set the bugle equal to each other: 3x=51

X=51/3=17

Then find x sub 2

17+x=180

X=180-17

X=163 degrees

I think it’s 17 cause 51/3 is 17.

What is the remainder when f(x) = x^2 + 14x − 8 is divided by (x − 5)? 103 88 87 72
il63 [147K]

Answer:

<h2>The answer is 87</h2>

Step-by-step explanation:

f(x) = x² + 14x - 5

To find the reminder when f(x) is divided by x - 5 , substitute the value of x into the above formula

That's

x - 5 = 0

x = 5

So we have

f(5) = 5² + 14(5) - 8

f(5) = 25 + 70 - 8

f(5) = 95 - 8

We have the final answer as

<h3>87</h3>

Hope this helps you

The 9th and the 12th term of an arithmetic progression are 50 and 65 respectively. find the common difference
Rzqust [24]

The first term of the arithmetic progression exists at 10 and the common difference is 2.

<h3>How to estimate the common difference of an arithmetic progression?</h3>

let the nth term be named x, and the value of the term y, then there exists a function y = ax + b this formula exists also utilized for straight lines.

We just require a and b. we already got two data points. we can just plug the known x/y pairs into the formula

The 9th and the 12th term of an arithmetic progression exist at 50 and 65 respectively.

9th term = 50

a + 8d = 50 ...............(1)

12th term = 65

a + 11d = 65 ...............(2)

subtract them, (2) - (1), we get

3d = 15

d = 5

If a + 8d = 50 then substitute the value of d = 5, we get

a + 8 * 5 = 50

a + 40 = 50

a = 50 - 40

a = 10.

Therefore, the first term is 10 and the common difference is 2.

The cost in dollars for removing p percent of pollutants from a river in Smith County is?
ZanzabumX [31]
Ok lets go ahead and see if the following answers can help:
<span>A) if p = 0.2 then C(p) = 157.52
B) if p = 0.95 then C(p) = 753.86
C) smallest p value that gives C(p) > or = 0. This is p = 0
D) largest INTEGER value for C(p) to exist or be >=0. This is p = 99. p = 100 gives 786000/0; does not exist. p > 101 starts giving negative numbers.
</span>I hope this has been of help
