H=-t^2+95
The y intercept here is 95, and it represented from where the boy threw the ball.

If he threw it from 95 ft above the ground, the best answer for where he is is on a bridge.
His backyard is at 0 ft (sea level). An underground cave is below sea level. A ladder is probably not 95 ft.

Final answer: D

Helia invested 4000 AED for 3 years with a compound interest rate of 1.5%, Calculate the worth of her investment at the end of t

sineoko [7]

Answer:

4180 AED

Step-by-step explanation:

Given data

Principal= 4000

Time= 3 years

Rate= 1.5%

The compound interest expression is given as

A= P(1+r)^t

substitute

A=4000(1+0.015)^3

A= 4000(1.015)^3

A= 4000*1.045

A= 4180

Hence the worth will be 4180 AED

Answer:

a=sqrt(d)-b, a=-sqrt(d)-b

Step-by-step explanation:

(a+b)^2=d

(a+b)=sqrt(d)

a+b=sqrt(d), a+b=-sqrt(d)

a=sqrt(d)-b, a=-sqrt(d)-b

Use log 2=a, log 3=b to evaluate log 216

Anuta_ua [19.1K]

Answer:

answer = 3(a +b)

Step-by-step explanation:

$log(2) = a \: log(3) = b \: \: \\ log(216) = log(2 \times 2 \times 2 \times 3 \times 3 \times 3) \\ = log( {2}^{3} \times {3}^{3} ) \\ = log(2^{3} ) + log( {3}^{3} ) \\ = 3 log(2) + 3 log(3) \\ = 3(a) + 3(b) \\ = 3(a + b) \\ \\ log(216) = 3(a + b)$
