Answer:

c) x=1.23

Step-by-step explanation:

a =3

b=2

c=-7

use quadratic equation where

{  ax}^{2}  + bx + c = 0 =  \frac{ - b \:  + or \:  -  \sqrt{ {b} ^{2}  - 4ac} }{2a}

-2+/- square root of (2^2- (4×3×-7) ) all that over 2x3

square root of (2^2-(4×3×-7) )

= 9.38083152

2×3=6

-2+or - 9.38 all that divided by 6

-2+9.38= 7.38÷6

x=1.23

or

-2-9.38 all divided by 6

-2-9.38= -11.38 ÷6

x= -1.9

all in all x can't be negative meaning <em>x</em><em>=</em><em>1</em><em>.</em><em>2</em><em>3</em>

Katena32 [7]

Answer:

C. 72 million

Step-by-step explanation:

Put the appropriate value of x into the correct formula and do the arithmetic.

... For the year 2002, x = 2002 -1980 = 22.

Then the population estimate is ...

... h(22) = 51.42 +15.473·log(22)

... = 51.42 +15.473·1.3424

... = 51.42 +20.77

... = 72.19 ≈ 72 . . . . million . . . . . matches choice C.

Daniel and William have some marbles. Daniel finds that 2/5 of the marbles he has is 4/5 the number marbles William has. William
fgiga [73]
If William has 195 marbles, let's find 4/5 of that.

195 * 4/5 = 156

156 is 2/5 of the marbles Daniel has.

Now we must multiply by the reciprocal

156 * 5/2 ( to find all of Daniel's marbles, not just 2/5) = 390 marbles

Daniel has 390 marbles.
