Answer:

total \: angle \: for \: a \: triangle = 180 \\ then \:  \\ 3x + 11 + 9x - 16 + 7x - 5 = 180 \\ 19x - 10 = 180 \\ 19x = 180 + 10 \\ 19x = 190 \\ x =  \frac{190}{19}  = 10 \\ thank \: yo

Answer:

x=10

Step-by-step explanation:

We know that the sum of all these angles is 180°, so, we solve for x using this information:

(9x-16)+(3x+11)+(7x-5)=180\\19x-10=180\\19x=190\\x=10

We can now use x to find the value of each angle:

9(10)-16=\\90-16\\=74\\\\

3(10)+11\\30+11\\41

7(10)-5\\=70-5\\=65

<em>Hope this helped! Have a good day.</em>

Suppose you are doing a binary search of the list [15, 18, 2, 19, 18, 0, 8, 14, 19, 14]. How many comparisons would you need to
Illusion [34]

Answer:

Three Times.

Step-by-step explanation:

First and foremost a binary search requires that the array be sorted in ascending or descending order.

After the initial step the search goes to the middle most value

i.e. [0, 2,8,14,14,15,18,18,19,19]  

will be the second 14, which is the first iteration.

Since 14 is less than 19 the search will eliminate  the lower half of the including 14, and will iterate again through the array:

[15,18,18,19,19]

The array will go to the middle most value which is 18, second iteration. Since 18 is less than 19, the program will eliminate the lower half and be left with two values i.e. [19,19].

The search will run once i.e. third iteration, and will return key value found.

ASAP HELP! BRAINLIEST! can someone help me with this? i need work shown. will mark brainliest!
ki77a [65]

Answer:

  4x^2 +12x +44 remainder 161x +84

Step-by-step explanation:

At each step, the quotient term is the ratio of the leading dividend term to the leading divisor term. The first quotient term, for example, is ...

  (4x^4)/(x^2) = 4x^2

The quotient term found this way is multiplied by the divisor and subtracted from the dividend. The difference is the new dividend and the process repeats.

You're done when the degree of the dividend is less than the degree of the divisor. This remainder can be expressed as a fraction with the divisor as the denominator.

  \dfrac{4x^4+5x-4}{x^2-3x-2}=4x^2+12x+44+\dfrac{161x+84}{x^2-3x-2}

If (x) = x+8 and g(x) = -4x-3, find (f+ g)(x).
Ede4ka [16]

Answer:

Answer=B

(f+g)(x)=-3x-5

Step-by-step explanation:

f(x)=x+8.

g(x)=-4x-3.

(f+g)(x) means f(x)+g(x),So

(x+8)+(-4x-3)

(add all same terms together)

=(x+(-4x))+(8+(-3))

=-3x+5

so,

(f+g)(x)=-3x+5
