frank reasoned that in the number 0.555, the valueof the 5 in the thousandths place is ten times the value of the 5 in the hundr

ollegr [7]

The reasoning of Frank is not correct. The value of 5 is the thousandths place is 1/10 times the value of 5 in the hundredths place instead of being 10 times.

In the question, we are given the number 0.555.

We can write it as:-

0.555 = 0.500 + 0.050 + 0.005

0.500 is the value of tenths place

0.050 is the value of hundredths place

0.005 is the value of thousandths place

We know that,

0.050*(1/10) = 0.050/10 = 0.005

Hence, the value of 5 is the thousandths place is 1/10 times the value of 5 in the hundredths place.

Answer: second option

Step-by-step explanation:

The standard form of a quadratic equation is:

$ax^2+bx+c=0$

Then, to write the quadratic equation given in the problem in standard form, you must substract 1 from both sides of the equation. Then you have:

$2x^2+5x-1=0$

Given the quadratic equation above, to find the value of $b^2-4ac$ you must substitute:

a=2; b=5 and c=-1 into $b^2-4ac$

Thenrefore, you obtain the following result:

$5^2-4(2)(-1)=33$

The equation y = 50(1.05)x models the growth of a mule deer population introduced into Guadalupe National Park in December 2015.

Answer:

J. 2085

Step-by-step explanation:

Fill in the desired value for y and solve for x.

1500 = 50(1.05^x)

30 = 1.05^x . . . . . . . divide by 50

log(30) = x·log(1.05) . . . . . take logarithms

x = log(30)/log(1.05) ≈ 69.71

Since x represents years after December 2015, x = 69.7 will be some time in mid 2085.
