sorry btw, no hablo espanol
Answer:
(√9)^2x-1/2 = 1/81
3^2x-1/2 = 1/(3)⁴. (as √9 = 3)
3^2x-1/2 = 3^-⁴. (as 1/a^m = a^-m)
as base are equal exponents are equal
so 3 gets cancelled out
2x-1/2 = -4
(4x-1)/2 = -4
4x-1 = -8
x = -7/4
hope this helps
Step-by-step explanation:
Answer:
45cm^2
Step-by-step explanation:
split the shape into a triangle and rectangle between points FE. Count how many squares up on the rectangle = 2cm
squares across = 9cm
2cm x 9cm = 18cm^2
for the triangle across would be 9cm
hight would be 6cm
9cm x 6cm = 54cm/2 = 27cm^2
18cm^2 + 27cm^2 = 45cm^2
Answer:
5.82
Step-by-step explanation:
6% = 0.06
5.49 * 0.06 = 0.3294
Rounded = 0.33
5.49 + 0.33 = 5.82
----------------------------
alternate methos
5.49 * 1.06 = 5.8194
rounded = 5.82
