Answer:
AT = 8
Step-by-step explanation:
Using the sine ratio in the right triangle
and sin45° = 
sin45° = 
= 
= 
Multiply both sides by AT
AT × sin45° = 8, that is
AT × = 8
Multiply both sides by
AT = 8

Answer:
a) 4⁻³ = 1/64 = 0.015625
b)13⁻² = 1/169 = 0.0059171598
c)(-3)⁻² = 1/-3² = 0.1111111111
Step-by-step explanation:
To solve the question above, when we have an integer ( positive or negative) that is raised to a negative power, this means the reciprocal of that integer raised to the positive power
Example:
a⁻ⁿ = 1/aⁿ
a) 4⁻³ = 1/4³
= 1/(4 × 4 × 4)
= 1/64
= 0.015625
b) 13⁻² = 1/13²
= 1/(13 × 13)
= 1/169
= 0.0059171598
c)(-3)⁻² = 1/-3²
= 1/(-3 × -3)
= 1/9
= 0.1111111111
Answer:
no solution
Step-by-step explanation:
6+r=5r-4(r+10)
6+r=5r-4r-40
6+r=r-40
46+r=r
46=0r
