Answer:
a = 11,390,625.
Step-by-step explanation:
a^x/6 = (a^1/6)^x
(a^1/6)^x = 15^x so:
a^1/6 = 15
1/6 ln a = ln 15
ln a = 6 ln 15
ln a = 16.2483
a = 11390625.
Im going to keep it simple, the answer is 9
If the legs of a right triangle are a and b and the hypotnuse is c then
a²+b²=c²
so we are given
the legs are x and √7
and the hypotnuse is √19
so
x²+(√7)²=(√19)²
x²+7=19
minus 7 both sides
x²=12
sqrt both sides
x=√12
x=√(4*3)
x=(√4)(√3)
x=2√3
Answer:
1. 8.4 2. 15
Step-by-step explanation:
1. 4x+8y= 40
wen y= 0.8
4x+8×0.8=40
4x=40-8×0.8
4x= 40- 6.4= 33.6
....x= 33.6/4 = 8.4
2. 3a+b= 54
wen b= 9
3a+ 9= 54
3a= 54- 9
3a=45
.....a = 45/3 = 15
