Step-by-step explanation:
huesenlig h 40°. ΜΑ. Which equation could be used to find the measure of ... base of a 350-foot-tall building. In right triangle ABC shown below, AC 729 inches, AB The angle of elevation from a person to.
After trial and error, you discover that - 2 works.
-2 || 3 16 18 -4
-6 -20 4
====================================
3 10 - 2 0
What you have left is a quadratic
3x^2 + 10x - 2 You can just use the quadratic formula to solve for the other 2 roots.
x1 = [ - 10 +/- sqrt(10^2 - 4*3*(-2) ) ] / 6
x1 = [ -10 +/- sqrt (100 + 24) ) /6
x1 = [ - 10 +/- sqrt(124) ) / 6
x1 = [ - 10 +/- 11.14 ] / 6 = 0.1893
x2 = [ - 21.14 ] / 6 = - 3.522
Answer
x1 = - 2
x2 = 0.1893
x3 = - 3.522
Answer:
20% of 25 is greater
Step-by-step explanation:
25% of 16 = 4
20% of 25 = 5
=(D-64)2
We move all terms to the left:
-((D-64)2)=0
We calculate terms in parentheses: -((D-64)2), so:
(D-64)2
We multiply parentheses
2D-128
Back to the equation:
-(2D-128)
We get rid of parentheses
-2D+128=0
We move all terms containing D to the left, all other terms to the right
-2D=-128
D=-128/-2
D=+64
