Answer:
8/ln(9)
Step-by-step explanation:
Let u=cos(x). Then du=-sin(x) dx.
If x=0, then u=cos(0)=1.
If x=pi/2, then ucos(pi/2)=0.
The intgral is rewriten as
Integrate((9^u (-du) , from u=1 to u=0)
-9^u/ln(9) |u=1..0)
Upperlimit goes in first no matter if it is tinier in value:
(-9^0/ln(9)--9^1/ln(9))
-1/ln(9)+9/ln(9)
8/ln(9)

Answer and Step-by-step explanation:
For the first one, x is equal to 61 (180 - 63 - 56 = 61)
and y = 4
51 = 12y + 3
48 = 12y
y = 4
For the second one,
x = 11
11x - 4 = 117
11x = 121
x = 11
y = 5
17y - 8 = 12 + 13y
4y = 20
y = 5

(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

Step-by-step explanation:
t1 = 10
t(n) = 3t_(n - 1) - 1
t(2) = 3*t(2 -1) - 1
t(2) = 3*t1 - 1
t(2) = 3*10 - 1
t_2= 30 - 1
t_2 = 29
t3 = 3*t2 - 1
t3 = 3*29 - 1
t3 = 87 - 1
t3 = 86
t4 = 3*t3 - 1
t4 = 3*86 - 1
t4 = 258 -1
t4 = 257

Consider the line y=7x-6.
Find the equation of the line that is perpendicular to this line and passes through the point (6, 2).
Find the equation of the line that is parallel to this line and passes through the point (6, 2).
Answers
Answer:
Case 1: 7y + x - 20 = 0 (Perpendicular)
Case 2: y - 7x + 40 = 0 (Parallel)
Step-by-step explanation:
Case 1: Perpendicular
Equation of the given line y = 7x - 6
Comparing with the general equation y = mx + c; m = 7
For two lines to be perpendicular, the product of their gradients is (-1) or we can also say; gradient of one line must be the negative inverse of the other gradient.
So the gradient of a line perpendicular to y = 7x - 6 should be (-1/7)
Now solving for the equation of the line using the formula
y - y = m(x - x ) where (x , y ) are the coordinates of the point.
substituting..
y - 2 = (-1/7)(x - 6)
7(y - 2) = -1(x - 6)
7y - 14 = -x + 6
7y + x -14 - 6 = 0
7y + x - 20 = 0 is the equation of the line perpendicular to y = 7x - 6 and passes through the point (6,2)
Case 2: Parallel
Equation of the given line y = 7x - 6
Comparing with the general equation y = mx + c; m = 7
For two lines to be parallel, they must have equal gradients.
So the gradient of a line parallel to y = 7x - 6 should be 7
Now solving for the equation of the line using the formula
y - y = m(x - x ) where (x , y ) are the coordinates of the point.
substituting..
y - 2 = 7(x - 6)
y - 2 = 7x - 42
y - 7x -2 + 42 = 0
y - 7x + 40 = 0 is the equation of the line parallel to y = 7x - 6 and passes through the point (6,2)

The solutions to a quadratic equation are 4 and -8. What is the quadratic equation?
Answers
Answer:
The quadratic equation is x^2 + 4x - 32 = 0
Step-by-step explanation:
(x - 4)(x+8) = 0
x^2 + 4x - 32= 0
Answer:
If the solutions (or roots, or zeros) are -4 and -8 then the factors are (x+4) and (x-8), so the equation would by:
Y=(x+4)(x-8) foil it out.
Y=x(2)+4x-(8)x-6)

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

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.
