X(4x-11)=15
+11 +11
5x=26
/5 /5
x=5.2
hope this helps :)
Answer:
B. 20
Step-by-step explanation:
Cos a = b/c
Cos 53° = b/25
b = 25 × 0,6 = 15
x = √(25² - 15²)
x = √(625 - 225)
x = √400
x = 20
When it will hit the ground then height is 0
<span>h(t)=-16^2+250
-16^2+250=0
16t^2=250
t^2=250/16
t=3.95 seconds
i hope this is right</span>
Answer: It is C because if you organize the equation numerically the equation is 18x^3+30x^2+12x+10. So it is 18.
The answer would be 0.3 * 15 = 4.5
