Answer:

7 seconds, 6 seconds

Step-by-step explanation:

a) For the object to reach the ground, the height from the ground has to be 0. therefore, let the function h = 0

0 = -16t^2 + 700

the amswers are + or - 6.61

we cant have negative time so it is approximately 7 seconds.

b) for the object to reach a 100 feet, h =100

100 = -16t^2 + 700

0 = -16t^2 + 600

solve: + or - 6.12

therefore it takes approximately 6 seconds to reach 100 feet.

Hari earns Rs 4300 per month. He spends 80% from his income. How much amount does he save in a year?

Lelu [443]

Answer:

Hari saves $ 10,320 in a year.

Step-by-step explanation:

Given that Hari earns $ 4300 per month, and he spends 80% from his income, to determine how much amount does he save in a year, the following calculation must be performed:

100 - 80 = 20

4300 x 0.20 x 12 = X

860 x 12 = X

10320 = X

Therefore, Hari saves $ 10,320 in a year.

What is the value of x in the equation below?

belka [17]

$remember$
$ln(a^b)=bln(a)$
$ln(e)=1$
$so$
$ln(e^x)=xln(e)=x$

$1+2e^{x+1}=9$
$minus \space\ 1 \space\ both \space\ sides$
$2e^{x+1}=8$
$divide \space\ both \space\ sides \space\ by \space\ 2$
$e^{x+1}=4$
$take \space\ ln \space\ of \space\ both \space\ sides$
$ln(e^{x+1})=ln(4)$
$(x+1)ln(e)=ln(4)$
$x+1=ln(4)$
$minus \space\ 1 \space\ from \space\ both \space\ sides$
$x=ln(4)-1$
$answer \space\ is \space\ C=ln(4)-1$
