Answer:
18
Step-by-step explanation:
30-60-90 triangles have a set of x values that you can plug your numbers into.
we know that the side length opposite to 30 is x
the side length opposite to 60 is xsqrt3
the side length opposite to 90 is 2x
from this we can gather that y=2x where x=9 therefore y=18
Answer:
x is all real numbers.
Step-by-step explanation:
Since there is only 1 value of y, it is a straight line. Since domain measures the range of x values, it can be any real number as the line goes from negative infinity to infinity.
Answer:
The standard form of a quadratic equation is ax2+bx+c=0, where a,b and c are real numbers and a≠0.
Answer:
the graph is attached
Step-by-step explanation:
This sort of equation makes it easy to find the x- and y-intercepts. Setting x to zero gives ...
y = -11 . . . . . the y-intercept
Setting y to zero gives ...
x = -11 . . . . . the x-intercept
You can plot these two points, then draw a line through them to complete the graph.
Every point on this line is a solution to the equation.
The experimental probability is how many times it landed on heads over the amount of times it was flipped.
The coin landed on heads 32 times out of 50 flips which is 32/50 which equals 0.64, which is 64%
The answer is D.
