Answer:
The domain represents the possible inputs of a function.
Step-by-step explanation:
The domain of a function is all of the possible x values that it can include.
These x values can also be called inputs of the function.
The x values are the inputs, and the y values are the outputs, in a function in the form of f(x) =
So, the statement best describing the domain of a function is The domain represents the possible inputs of a function.

What is the area of the right triangle shown in the image.
Answer:
24 sq. in
Step-by-step explanation:
To find the area of a triangle, you multiply both sides by one another, then divide the product in half.
In this case it would go along the lines of:
6 x 8 = 48
48/2 = 24
And 24 is the desired answer.

d. Keisha did not make a mistake.
Answer:
d. Keisha did not make a mistake
Step-by-step explanation:
3+(-4)-7
3+(-4)+(-7) adding negatives is the same as subtracting
3+(-11) -4 and -7 do make -11
-8 3 and -11 do make -8
So she did it correctly, which means d is the right answer.

Jack is 5 years older than Mary. In four years the sum of their age is 33 years old. What are their ages?
Answer:
mary=10 jack=15
Step-by-step explanation:
After 4 years Mary (x+4), Jack's age (x+5) + 4.
sum of the ages after 4 years :(x+4) + (x+5) +4=33
Simplifying the equation:
2x+13 = 33 ----->> 2x=20----->>>>x = 10 Mary's age
10 + 5 = 15 which is Jack's age.

(whole secant) x (external part) = (tangent)^2
(4+x) * 4 = 8^2
Distribute
16+4x = 64
Subtract 16 from each side
4x = 48
Divide each side by 4
4x/4 = 48/4
x = 12
Answer: 12
Step-by-step explanation: 8*8 = 4(4+x), which is equal to 64 = 16 + 4x, subtract 16 from both sides, 48 = 4x, divide both sides by 4 to isolate x, 12 = x
Find the slope of the line that contains
the points (3, 2) and (-3, 8).
Answer:
-1
Step-by-step explanation:
To find the slope given two points

= ( 8 - 2)/( -3 -3)
= 6 / -6
= -1

Which expression will simplify (3a + 6) (7a - 2)?
Answer:
63a + 6
Step-by-step explanation:
we have to first simplify this
(3a+6)(7a-2)
21a-6+42a+12
63a+6
Answer:
Step-by-step explanation:
Use FOIL method
(3a+ 6)(7a - 2) = 3a* 7a + (3a)*(-2) + 6*7a + 6*(-2)
= 21a² - 6a + 42a - 12 {Combine like terms}
= 21a² + 36a - 12

Answer:
No, because the longest side is too short to be the hypotenuse of a right triangle.
Step-by-step explanation:
To see if the sides form a right triangle
6² + 8² = 9²
36 + 64 = 81
100 ≠ 81
The the 3rd side is too short

Solve the following trigonometric equation over the interval of [0,2π). Show your work, thank you!
[tex] \large{2sin \theta tan \theta = - 3}[/tex]
Answer:
[tex] \rm \displaystyle \theta = \{ {150}^{ \circ} , {240}^{ \circ} \}[/tex]
Step-by-step explanation:
we would like to solve the following equation:
[tex] \displaystyle 2 \sin( \theta) \tan( \theta) = - 3[/tex]
to do so we need to put the equation in term of a function of a angle therefore rewrite tanθ:
[tex] \displaystyle 2 \sin( \theta) \cdot \frac{ \sin( \theta) }{ \cos( \theta) } = - 3[/tex]
simplify multiplication:
[tex] \displaystyle \frac{ 2\sin^{2} ( \theta) }{ \cos( \theta) } = - 3[/tex]
cross multiplication:
[tex] \displaystyle 2\sin^{2} ( \theta) = - 3 \cos( \theta) [/tex]
isolate -3cosθ to left hand side and change its sign:
[tex] \displaystyle 2\sin^{2} ( \theta) + 3 \cos( \theta) = 0[/tex]
well we can rewrite sin²θ by applying Pythagorean theorem and that yields:
[tex] \rm \displaystyle 2(1 - \cos^{2} ( \theta)) + 3 \cos( \theta) = 0[/tex]
distribute:
[tex] \rm \displaystyle 2 - 2\cos^{2} ( \theta) + 3 \cos( \theta) = 0[/tex]
now notice that our equation ended up with a pattern and that is Quadratic thus by letting cosθ be x to transform the equation:
[tex] \rm \displaystyle 2 - 2 {x}^{2} + 3 x = 0[/tex]
rearrange it to standard form:
[tex] \rm \displaystyle - 2 {x}^{2} + 3 x + 2 = 0[/tex]
divide both sides by -1:
[tex] \rm \displaystyle 2 {x}^{2} - 3 x - 2 = 0[/tex]
well we can factor the quadratic to do so rewrite -3x as -4x+x:
[tex] \rm \displaystyle 2 {x}^{2} - 4 x + x - 2 = 0[/tex]
factor out 2x:
[tex] \rm \displaystyle 2x ({x}^{} - 2)+ x - 2 = 0[/tex]
factor out 1:
[tex] \rm \displaystyle 2x ({x}^{} - 2)+ 1(x - 2 ) = 0[/tex]
group:
[tex] \rm \displaystyle (2x + 1)(x - 2 ) = 0[/tex]
by Zero Product property we obtain:
[tex] \rm \displaystyle \begin{cases} 2x + 1 = 0\\ x - 2 = 0 \end{cases}[/tex]
cancel 1 from the first equation and add 2 to the e equation:
[tex] \rm \displaystyle \begin{cases} 2x = - 1\\ x = 2\end{cases}[/tex]
substitute back:
[tex] \rm \displaystyle \begin{cases} 2 \cos( \theta) = - 1\\ \cos( \theta) = 2\end{cases}[/tex]
since cosθ is only defined for the interval [1,-1] the second equation is false for any value of θ but we can still continue the first equation
[tex] \rm \displaystyle \begin{cases} 2 \cos( \theta) = - 1\\ \cos( \theta) \neq 2\end{cases}[/tex]
divide both sides by 2:
[tex] \rm \displaystyle \cos( \theta) = \frac{ - 1} {2}[/tex]
by unit circle we acquire:
[tex] \begin{cases} \rm \displaystyle \theta = {150}^{ \circ} \\ \theta = {240}^{ \circ} \end{cases}[/tex]
add period of 2nπ:
[tex] \begin{cases} \rm \displaystyle \theta = {150}^{ \circ} + 2n\pi\\ \theta = {240}^{ \circ} + 2n\pi \end{cases}[/tex]
for the interval [0,2π) θ is only defined when n is 0 Thus:
[tex] \begin{cases} \rm \displaystyle \theta = {150}^{ \circ} + 2(0)\pi\\ \theta = {240}^{ \circ} + 2(0)\pi \end{cases}[/tex]
simplify:
[tex] \begin{cases} \rm \displaystyle \theta = {150}^{ \circ} \\ \theta = {240}^{ \circ} \end{cases}[/tex]
hence,
θ is equal to 150° and 240°

When an object is dropped from a tall building, it falls about 16 feet in the first second, 48 feet in the second second, and 80 feet in the third second, regardless of its weight.
How many feet would an object fall in the tenth second?
Answer:
the object will fall 5060 feet in 10 second.
Step-by-step explanation:
g= 9.8m/s^2 and 9.8×3.33=32.67 feet/s^2.
initial velocity (u)= 16 feet/second
time taken(t)=10 second
final velocity(v)= ?
now,
V= u+ GT
=16+32.67×10
=342.67feet/second
again
distance covered= VT+1/2gt^2
=342.67×10+1/2×32.67×100
=3426.7+1633.33
=5060 feet

Answer:
60% decrease in area
