If the cos A= 9/41 , what does the tan A equal?
Answer:
tanA = 40/9
Step-by-step explanation:
Try to construct a right-angled triangle with it's adjacent side=9 and hypotenuse = 41,
By pyth. theorem, we can get the remaining side (opposite side)
= √(41^2 - 9^2)
= 40
tanA = oppside side/ adjacent side
tanA = 40/9
Y=2x-10
3x-7y=37 I need to solve by substitution
Answer:
x=3, y=-4
Step-by-step explanation:
3x-7(2x-10)=37
3x-14x+70=37
-11x=37-70
-11x=-33
x=3
y=2(3)-10
y=6-10
y=-4

Domain and range for exponential function y=3x
The domain of the exponential function 3ˣ is the set of all real numbers (or) (-∞, ∞).
Range is [tex]\begin{bmatrix}\mathrm{Solution:}\:&\:f\left(x\right) > 0\:\\ \:\mathrm{Interval\:Notation:}&\:\left(0,\:\infty \:\right)\end{bmatrix}[/tex]
What is an exponential function?An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.
We know that the domain of a function y = f(x) is the set of all x-values (inputs) where it can be computed and the range is the set of all y-values (outputs) of the function.
From the graphs of f(x) = 3ˣ, we can see that an exponential function can be computed at all values of x. Thus, the domain of an exponential function is the set of all real numbers (or) (-∞, ∞).
Thus, the domain is the set of all real numbers (or) (-∞, ∞).
Range is [tex]\begin{bmatrix}\mathrm{Solution:}\:&\:f\left(x\right) > 0\:\\ \:\mathrm{Interval\:Notation:}&\:\left(0,\:\infty \:\right)\end{bmatrix}[/tex]

need some help with this
Answer:
c. infinitely many solution
Answer: C
Step-by-step explanation:
5 + -2x = 4 + -2x + 4 + x
Reorder the terms:
5 + -2x = 4 + 4 + -2x + x
Combine like terms: 4 + 4 = 8
5 + -2x = 8 + -2x + x
Combine like terms: -2x + x = -1x
5 + -2x = 8 + -1x
Solving
5 + -2x = 8 + -1x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'x' to each side of the equation.
5 + -2x + x = 8 + -1x + x
Combine like terms: -2x + x = -1x
5 + -1x = 8 + -1x + x
Combine like terms: -1x + x = 0
5 + -1x = 8 + 0
5 + -1x = 8
Add '-5' to each side of the equation.
5 + -5 + -1x = 8 + -5
Combine like terms: 5 + -5 = 0
0 + -1x = 8 + -5
-1x = 8 + -5
Combine like terms: 8 + -5 = 3
-1x = 3
Divide each side by '-1'.
x = -3
Simplifying
x = -3
Can anyone explain to me what to do here? I've been looking at this for like..days and...I still don't get it...
Answer:
I think u have to find the distance.
Each point is given a distinct letter and like wise you have to count the distance between the two points given.
Step-by-step explanation:
Like, 1)distance between A and R when A = -11 and R = -9
their distance is 2 units.
Likewise, 2) RY = 6 units
3) EU = 7 units
4) WD = 5 units
5) EL = 12 units

choose the best selection for the quadrilateral with vertices at following points
0,0 -2,3 7,0 5,3
Answer:
The quadrilateral has two pairs of opposite parallel sides and (from the graphing of the points) it is slanted from the vertical, therefore, it is a;
B. Parallelogram
Step-by-step explanation:
The coordinates of the vertices of the given quadrilateral are;
(0, 0), (-2, 3), (7, 0), (5, 3)
Arranging the coordinates according to their y-values and labelled gives;
A(-2, 3), B(5, 3), C(0, 0), D(7, 0)
The graph of the points created with Microsoft Word and Microsoft Excel is attached
From the graph, we have;
Segment AB is parallel to segment CD
The length of segment AB = √((5 - (-2))² + (3 - 3)²) = 7
The length of segment CD = √((7 - 0)² + (0 - 0)²) = 7
∴ The length of segment AB = The length of segment CD
The distance between segment AC and segment BD = Length of segment AB at point A = Length of segment CD at point C
∴ Segment AC is parallel to segment BD (The distance between two parallel lines is the same all through)
The quadrilateral is also observed to be slant from the vertical
Therefore the quadrilateral is a parallelogram

twice the difference of c and 19
Answer:
2(c - 19)
Step-by-step explanation:
Twice the difference of c and 19
2 (c - 9)
When it says "twice the difference.." it means you will times the difference of c - 19 by 2
Answer:
Difference of c and 19=c-19
Twice of (c-19)=2(C-19).
So, the final answer is 2(c-19).
