Answer:
a = 5
Step-by-step explanation:
According to the factor theorem, if x + 2 is a factor, then by dividing the polynomial by the binomial, we are meant not to have a remainder
In this case, the remainder would be zero
So, if we set the binomial equals zero and substitute the x-value into the polynomial, we are supposed to have 0
So we have this as;
x + 2 = 0
x = -2
-2^3 -2(-2)^2 -2(a) + 6 = 0
-8-8-2a + 6 = 0
-16 + 2a + 6 = 0
2a -10 = 0
2a = 10
a = 10/2
a = 5

if y^17-17 is divided by y+1 , the remainder is
Answers
Answer:
Step-by-step explanation:
a) We have 15! as the product of 1 to 15 natural numbers. Since 17 is prime there will be no factor common to these
By actual division we find
15! (mod 17) =16
From this we deduce
even 16! mod 17 = 16 = -1
According to Wilson theorem
(17-1)! = -1 mod 17
Thus verified 17 is prime
Hence 15! (mod 17) =-1=16
-----------------------
b) 2(26!) is divided by 29
Since 29 is prime
(29-1)! = -1 mod 29
28! = -1 mod 29 = 28
When divided this gives 25 as remainder

What is the first term for an arithmetic sequence with a12 = 56 and a21=101?
Answers
Explanation:
an = a + (n - 1)d
a12 = a + 11d = 56, first equation
a21 = a + 20d = 101, second equation
Subtract the second equation from the first equation, cancelling +a and -a
11d - 20d = 56 - 101
-9d = -45
d = 5
Subtitute d into the first equation
a + 99 = 56
a = -43
a refers to the first term, hence the first term is -43.

Answer:
[tex]x = \frac{15}{7} , \ y = - \frac{1}{7}[/tex]
Step-by-step explanation:
2x - 5y = 5 ---------- ( 1 )
x + y = 2 ------------ ( 2 )
x = 2 - y ---------( 3 )
Substitute x in ( 1 ) :
2( 2 - y) - 5y = 5
4 - 2y - 5y = 5
- 7y = 5 - 4
-7 y = 1
[tex]y =- \frac{1}{7}[/tex]
Substitute y in ( 2 ) :
[tex]x + y = 2\\\\x -\frac{1}{7} = 2\\\\x = 2 + \frac{1}{7}\\\\x = \frac{14 + 1}{7}\\\\x = \frac{15}{7}[/tex]

Complete these ordered pairs for this equation.
(0, ), (-1,), (1, ) y=2x+1
Help
Answers
Answer:
The completed ordered pair are;
(0, 1), (-1, -1), and (1, 3)
Step-by-step explanation:
The ordered pair, (x, y), presents the corresponding values of 'x' and 'y' based on a given relationship, or equation
The given relationship between 'x', and 'y' is, y = 2·x + 1
Therefore, given that the x-values (first of two values, separated by the coma) are given, we have;
In the given incomplete pair (0, ), when x = 0, therefore, y = 2 × 0 + 1 = 1
The complete ordered pair is (0, 1)
Similarly, for (-1, ), we have;
When x = -1, y = 2 × (-1) + 1 = -1
The complete ordered pair is (-1, -1)
We also have for the incomplete pair, (1, )
When x = 1, y = 2 × 1 + 1 = 3
The complete ordered pair is (1, 3)
The completed ordered pair for the equation, y = 2·x + 1, are therefore;
(0, 1), (-1, -1), and (1, 3).

Answers
Answer:
6/7 or -6/7
Step-by-step explanation:
Pythagoras.
c² = a² + b²
the trigonometric functions in a norm circle (radius = 1) express the side lengths of inscribed right-angled triangles.
sin(x) is one side (e.g. "a") "touching" the 90 degree angle.
cos(x) is the other side ("b") of the 90 degree angle.
and the radius (1) is the Hypotenuse (the side opposite of the 90 degree angle), which is called "c" in the formula of Pythagoras.
so, we have
1² = (sqrt(13)/7)² + b²
b² = 1² - (sqrt(13/7)² = 1 - 13/49 = 49/49 - 13/49 = 36/49
b = cos(x) = sqrt(36/49) = 6/7
as we don't know anything about the angle x except that it has a positive sin(x) value, the cos(x) value can be positive or negative depending on if x is an angle of the first or of the second quadrant in the norm circle.
in the first quadrant cos(x) is also positive, in the second quadrant cos(x) is negative.
the third and fourth quadrants do not apply, as sin(x) would be negative for both.

Explanation:
(First, we need to find the side opposite to 40 degrees)
Let the side be ‘s’
tan(40) = s/6 (Opposite/Adjacent)
tan(40) x 6 = s
s ≈ 5.03 units
Area of triangle base = 1/2 x Base x Height = 1/2 x 6 x 5.03 = 15.09 square units
Area of prism = Base Area x Height = 15.09 x 10 = 150.9 cubic units
An animal shelter provides shelter for dogs and cats. The animal shelter currently has a total of 117 animals. If the number of cats is 3 more than 5 times the number of dogs, how many dogs and cats are currently at the animal shelter?
Answers
Answer:
98 cats and 19 dogs
Step-by-step explanation:
cat = c
dog = d
The animal shelter currently has a total of 117 animals
c + d = 117
c = 117 - d
the number of cats is 3 more than 5 times the number of dogs
c = 3 + 5d
subtitute c
117 - d = 3 + 5d
117 - 3 = 5d + d
114 = 6d
6d = 114
d = 114/6 = 19
so, the cat is 117-19 = 98
