Answer:
Step-by-step explanation:
let present age of
Dylan=x
Renee=y
x+y=57
9 years ago
x-9=2(y-9)=2y-18
x=2y-18+9=2y-9
so 2y-9+y=57
3y=57+9=66
y=66/3=22
x+22=57
x=57-22=35
Dylan's present age=35 years
Answer:
c.) aₙ = 5 × 4ⁿ⁻¹
Explanation:
Geometric sequence: aₙ = a(r)ⁿ⁻¹
where 'a' resembles first term of a sequence, 'r' is the common difference.
Here sequence: 5, 20, 80, 320,...
First term (a) = 5
Common difference (d) = second term ÷ first term = 20 ÷ 5 = 4
Hence putting into equation: aₙ = 5(4)ⁿ⁻¹
Answer:
A. T, U
Step-by-step explanation:
T and U are stretched across the paper. the others seem a bit close or smaller to the size of X and Y, but when you look at T and U they seem longer than X an Y
Hope this helps!!! :)
<span>Line ET is tangent to circle A at T
</span>
∴ ET ⊥ TN
∴ ∠ ETN = 90
<span>the measure of Arc TG = 70
</span>
∠ TNG = half <span>the measure of Arc TG = 0.5 *70 = 35
</span>
<span>Δ ETN ⇒ The sum of all angles = 180
</span>
<span>∴∠ GET = ∠ NET = 180 - (90 + 35 ) = 55
</span>
∴ The correct answer is option <span>A. 55°</span>
