99/10 as a mixed fraction would be 9 9/10
Answer:
Step-by-step explanation:
Statements Reasons
1). AD ≅ BC 1). Given
2). ∠D ≅ ∠C 2). Given
3). ∠DEA ≅ ∠CEB 3). Vertically opposite angles
4). ΔADE ≅ Δ BCE 4). AAS postulate of congruence
5). AE ≅ BE 5). CPCTC
Hence, proved.
The value at point ( 1, 1 ) is 8.
<u>Explanation:</u>
Given
3y³ = 2x⁹ + 1
y³ = 2/3x⁹ + 1/3
y = ∛2/3 x⁹ + 1/3
We need to first find dy/dx which is the first derivative and then d²y/dx² which is the second derivative


Put the value of (1,1) : x = 1 and y = 1 in d²y/dx² equation


Therefore, the value is 8.
