Answer: 8
Step-by-step explanation:
Consider the given quadratic equation 
Comparing the given quadratic equation to the general equation 
, we get a= 1, b=0 and c= -50
So, the solution to the quadratic equation is given by:
So, the solutions to the given quadratic equation are .
Answer:
A(0,7)
Step-by-step explanation:
The y-intercept is (0,7). The y-intercept is the point in which the line or the function crosses the y-axis.
5. 6/10-2/10=4/10 or 2/5 or 1/2.5
6. 4/5-1/5=3/5 or 1.5/2.5
7. 3/4-2/4=1/4 or .5/2
8. 4/6-2/6=2/6 or 1/3 or .5/1.5
Answer:
A geodesic dome is composed of two different types of triangular panels. One of these is an isosceles triangle. In one geodesic dome, the measure of hte third angle is 58.5 degrees more than the measure of either of the two angles. Find the measure of the three angles.
Step-by-step explanation:
d = 36 mi the distance traveled in one direction
t1 = 1.5 hr the time of the trip upstream
t2 = 1 hr the time of the trip downstream
s = the speed of the stream
v = the speed of the boat in still water
the speed of the boat upstream is: v - s
the speed of the boat downstream is: v + s
traveling upstream
(v - s)*t1 = d
(v - s)*1.5 = 36
traveling downstream
(v + s)*t2 = d
(v + s)*1 = 36
by solving the system of equations
(v - s)*1.5 = 36
v + s = 36
we find
s = 6 mph
v = 30 mph
