Using the law of sins:
side a / sin (angle A) = side b / sin(Angle B)
Side a is opposite angle A, so from the picture we know side a = 50, angle A is 58 degrees and angle B is 48 degrees.
replace those values in the formula we get:
50 / sin(58) = b/ sin(48)
so now we can cross multiply the 2 fractions to get:
50 * sin(48) = b*sin(58)
to get b by itself, divide both sides by sin(58) to get:
b = (50*sin(48)) / sin(58)
b = 43.82
You may need to round the answer as needed.
Answer:
y=3/4x+2
Step-by-step explanation:
The slope intercept formula is y=mx+b
b=2 because it is the y intercept
m is the slope
from (0,2) I counted how many points over and up the next point directly on the two lines was , which was point (4,5)
it was 4 to the right and 3 up
slope is rise over run so the slope is 3/4
The parabola has 2 x intercepts, so quadratic equations has 2 real roots (-6), and 3
we can write (x+6)(x-3)=0 , x²+6x-3x-18=0, y=x²+3x-18
check y int =-18 on the graph
y=1x²+3x-18
Answer:
D. x + 6
Step-by-step explanation:
In the given graph, we have 3 x-intercepts values, which are points at which the line intercepts the x-axis. They are, -6, -3 and 0.
Each of these x-intercepts can be written as a factor of a polynomial function as follows:
x = -6
x = -6 + 6
x + 6 = 0
x = -3
x = -3 + 3
x + 3 = 0
x = 0
Therefore, the factor of the polynomial function must be: x + 6
I believe 1 & 2 are both C
