5x-25=5, x=6; multiply the 5 times x and negative 5, then add 25 to both sides, and divide by 5 to get 6.
You have to solve 3 equations pretty much simultaneously here using the x and y values in the general form of the quadratic equation
Start with the first values of x=0 and y=5.1 to solve for c:
so c = 5.1
Next use the second x and y values along with the value of c in the next equation:
gives you
-2.07 = a + b. Solve this for a:
a = -2.07 - b
Finally use the third set of numbers with the c value AND the subbed value for a:
1.17 = 9(-2.07 - b)+ 3b + 5.1 which simplifies to:
1.17 = -18.63 - 9b + 3b + 5.1 which further simplifies to:
14.7 = -6b and b = -2.45
Now you have c and b, let's find a using one of the simplified equations:
-2.07 = a + b
-2.07 = a - 2.45
a = .38
So here's your equation:
Answer:
d
Step-by-step explanation:
Answer:
14 mi
Step-by-step explanation:
V = 718.38 mi³, r = 7 mi, find h
Use V = πr²h/3
718.38 = 3.14 * 7² * h/3
718.38 = 51.287 h
h = 718.38/51.287 = 14 mi
The said triangle that is asked is a right triangle which has a proportion on each angle of 3 and 6. These proportions are the angles, which is 45, 45, and 90, which also means that the two rays of the triangle are the same and proved that ab= ac that makes the angle a is a 90 degree in value.
