So pemdas
square root of 9 means 9^(1/2) so it counts as an exponent so
9=3 times 3 so square root of 9=3
square root of 25
do pemdas so exponents before division
25=5 times 5 so
square root of 25==5 so

3/5=0.6

Answer:

$N(t) = 37.1(1.38)^t$

Step-by-step explanation:

Exponential function:

An exponential function has the following format:

$N(t) = N(0)(1+r)^t$

In which N(0) is the initial value and r is the rate of change, as a decimal.

37.1 million in July 1998

This means that $N(0) = 37.1$

$N(t) = 37.1(1+r)^t$

In July 2005, the internet was linked by a global network of about 353 million host computers.

This is 2005 - 1998 = 7 years, so $N(7) = 353$ . We use this to find r.

$N(t) = 37.1(1+r)^t$

$353 = 37.1(1+r)^7$

$(1+r)^7 = \frac{353}{37.1}$

$\sqrt[7]{(1+r)^7} = \sqrt[7]{\frac{353}{37.1}}$

$1 + r = (\frac{353}{37.1})^{\frac{1}{7}}$

$1 + r = 1.38$

The formula is:

$N(t) = 37.1(1.38)^t$

mestny [16]

Answer:

system of equations are

$x+y=376$

$4x+7y=2119$

Step-by-step explanation:

Let x = number of children's books sold,

and let y = the number of adult books sold

The library sells 376 books at its annual used-book sale

so, we get equation as

$x+y=376$

Children's books cost $4

So, total cost of children book is 4x

adult books cost $7

So, total cost of adult book is 7y

so, we get total cost is 4x+7y

he sale takes in a total of $2119

so, we get equation as

$4x+7y=2119$

so,

system of equations are

$x+y=376$

$4x+7y=2119$

Jay paid $126 to rent a car for 4 days. Stephanie paid $184.50 to rent a car for 6 days.

vazorg [7]

You need to divide the amount by the number of days to find the price per day so
Jay paid $126 for 4 days
$126/4=$31.50 per day
and
Stephanie paid $184.50 for 6 days
$184.50/6=$30.75
So
The answer is
C. Stephanie paid the lower daily rate of $30.75.

.Write the quadrants/axes in which the following points lie a) (2,-3) b)(0,8) c)(-1,-2) d)(4,7)

natka813 [3]

Answer:

[see below]

Step-by-step explanation:

Quadrant One has a positive value for both x and y. (+ , +)

Quadrant Two has a negative x value. (- , +)

Quadrant Three has a negative value for both x and y. (- , -)

Quadrant Four has a negative y value. (+, -)

Therefore:

(2, -3) would be plotted in Q4. It does not lie on any axis.

(0, 8) would be on the positive y-axis. (0 is neither negative nor positive.)

(-1, -2) would be plotted in Q3. It does not lie on any axis.

(4, 7) would be plotted in Q1. It does not lie on any axis.
