Answer:
no you cant use these three ratios for any right triangle
Step-by-step explanation:
Ratios: 0.38, 0.93, 0.36
I\
0.38 I \ 0.93 right triangle
I \
I_____\
0.36
so this means a^2 + b^2 = c^2 would be true if these ratio worked
(0.36)^2 + (0.38)^2 = (0.93)^2
0.1296 + 0.1444 = 0.8649 NOT TRUE
The 2 angles are vertical angles, which mean they are equal.
Set the two equations to equal and solve for x:
4x + 7 = 5(x-4)
Use distributive property on the right side:
4x + 7 = 5x -20
Add 20 to each side:
4x +27 = 5x
Subtract 4x from each side:
27 = x
X = 27
I would say to look for any like terms to combine, looking at the range of different variables and terms on both sides of the equation.
Answer:
y = tan(x -π) -1
Step-by-step explanation:
It looks like a straight tangent function shifted down one unit. Since the tangent function has a period of π, ...
tan(x -π) = tan(x)
so you're only looking for the function that has a translation downward of 1 unit. Of course that translation is accomplished by adding -1 to the original function.
The appearance of the graph is of ...
y = tan(x) -1
The choice that is equivalent to this is ...
y = tan(x -π) -1
Answer:
Step-by-step explanation:
x = -4 and x=1
The solutions to the equation x^2 +3x -4 = 0 will be given by the points at which the graph intercepts the x-axis.
By looking at the graph, we can clearly see that the graph intercepts the x-axis at x=-4 and x=1.
One of the roots is located between -4 and -3, and the other one between 0 and 1.
