Answer:
The index of a number says how many times to use the number in a multiplication. It is written as a small number to the right and above the base number. In this example: 82 = 8 × 8 = 64. The plural of index is indices. (Other names for index are exponent or power.)
Step-by-step explanation:
Answer:
x = 34
Step-by-step explanation:
ΔABD and ΔBCD are both isosceles triangles
In ΔABD
AB =AD, hence ∠ABD = ∠ADB ( base angles are equal )
∠ABD = 
= 
= 68°
∠DBC = 180° - 68° = 112° ( straight angle )
∠BCD = x = 
= 
= 34
Answer:
B
Step-by-step explanation:
The data of the poulation increased.
Y-y1 / x-x1 to get slope
5 - 1 / 9 - 4
m (slope) = 4/5
plug in one point to get b
1 = 4/5(4) + b
1 = 16/5 + b
b = -15/5
y = 4/5x - 15/5
