find the exact value of sin a = 4/5, a lies in quadrant 2, and cos B = 2/5, B lies in quadrant 1 find cos(a-b)
Answer:
Cos(a - b) = 0.959
Step-by-step explanation:
We know that:
Sin(a) = 4/5
Such that a is on the first quadrant (between 0° and 90°)
then:
Sin(a) = 4/5
Asin(sin(a)) = Asin(4/5)
a = Asin(4/5) = 53.13°
And:
Cos(b) = 2/5
Then:
Acos(Cos(b)) = Acos(2/5)
b = Acos(2/5) = 36.67°
Then:
Cos(a - b)
where:
a = 53.13° and b = 36.67°
Then:
Cos(a - b) = Cos(53.13° - 36.67°) = 0.959
Jackie correctly solved this equation:
4/x-2+1/x^2-4=1/x+2
Which statement describes the solutions she found?
Answer:
answer is A
Step-by-step explanation:
took the test :)
The option (A) she found one valid solution and no extraneous solution is correct, and x = -11/3 or -3.66.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
We have the equation:
[tex]\rm \dfrac{4}{x-2}+\dfrac{1}{x^2-4}=\dfrac{1}{x+2}[/tex]
After taking LCM
4x + 9 = x - 2
x = -11/3
or
x = -3.66
Thus, option (A) she found one valid solution and no extraneous solution is correct, and x = -11/3 or -3.66.

help please
Step-by-step explanation:
In order to find the slope, we must know the formula needed.
[tex]\frac{y2}{x2} -\frac{y1}{x1} =m[/tex]
Using 2 given points, we can subtract both and receive our final answer.
Points that are provided:
(4, 3)(1, -1)Substitute the given points into the formula format.
Then, solve.
[tex]\frac{3}{4} -\frac{-1}{1} =\frac{4}{3}[/tex]

Answer:
61 inches squared
Step-by-step explanation:
find the area of the rectangle then the area of the triangle and add.
Answer:
61 in²
Step-by-step explanation:
first u work out the rectangle. so u do 4 times 10 which is 40 . then u do 1.5 plus 1.5 plus 4 which equals 7 . then u do 7 times 6 which is 42 . 42 two divide by 2 = 21 . 21 plus 40 equals 61. answer 61.
area of triangle: base times height divide by 2 .
to work out area of rectangle : 4×10=40 in²
1.5+1.5+4= 7 in
area of triangle: 7×6=42 then divide by 2 = 21 in²
plus them to get the area of arrow : 21+40=61 in²

Enter the value of w so the expression -5 +0.6W is equivalent to w (2.5 – 0.3w)
9514 1404 393
Answer:
w = -2 or 8 1/3
Step-by-step explanation:
Setting the two expressions equal makes a quadratic equation:
-5 +0.6w = w(2.5 -0.3w)
0.3w^2 -1.9w -5 = 0 . . . . . . subtract the right-side expression
3w^2 -19s -50 = 0 . . . . . . . multiply by 10 to give integer coefficients
(3w -25)(w +2) = 0 . . . . . . . factor
We can use the zero product rule to find the solutions. The product will be zero only if a factor is zero.
3w -25 = 0 ⇒ w = 25/3 = 8 1/3
w +2 = 0 ⇒ w = -2
The values of w that make the two expressions equivalent are -2 and 8 1/3.

Which statement describes the definition of a function?
Answer:
an activity or purpose natural to or intended for a person or thing.
Step-by-step explanation:
: >
The function definition is given below..
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
A function is a relation that has an input and an output.
All the possible outputs are called codomains.
The inputs are called the domains.
The outputs are called the range.
A function can be many-to-one but not one-to-many.
Example:
f(x) = x²
For x = 1 and x = -1
f(x) = (1)² = 1 and f(x) = (-1)² = 1
This is many to one.
Thus,
The function definition is given above.
