There are 35 bees in the hive when it is first observed on Saturday. After 3 days, there are 42 bees. It is determined that the population of bees increases exponentially. How many bees are will there be after 30 days? Express your answer as an exact value and rounded to the nearest whole number

105

Step-by-step explanation:

every 3 days, 7 bees are added.

10x3=30 (days)

10x7=70 (bees)

70+35=105

answer: the answer is d

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
