Novay_Z [31]

Answer:

Step-by-step explanation:

40 + 15 + 0.25m = 45 + 0.35m

55 + 0.25m = 45 + 0.35m

10 = 0.10m

m = 100 miles

The estimated number of organisms in a population after t days is shown in the table below. t days estimated number of organisms

Lelu [443]

Answer:

The function $n=591.68(1.2056)^t$ best models the situation.

Step-by-step explanation:

The values in the table do not lie over a straight line because their slope is not a constant; for example

$m_1=\frac{1250=860}{4-2} =195$

$m_2=\frac{1850-1250}{2}=275$

we see here that $m_1\neq m_2$ therefore a linear equation cannot represent this situation.

The values in the table are increasing exponentially , therefore the equation modeling the situation will be of the form:

$n=ab^t$

we take two points from the table for evaluating $a$ and $b$ namely points $(2,860)$ and $(4,1250)$

thus we have

(1). $860=ab^2$

(2). $1250=ab^4$

From equation (1) we solve for $a:$

$a=\frac{860}{b^2}$

and put this value into equation (2)

$1250 =\frac{860}{b^2}b^4$

$b^2=\frac{1250}{860}$

$\boxed{b=1.2056}$

with this value $b$ , we solve for $a$ in equation (1):

$860=a(1.2056)^2$

$a=\frac{860}{(1.2056)^2}$

$\boxed{a=591.68}$

Thus we have the equation

$\boxed{n=591.68(1.2056)^t}$

James hiked on two trails. The first trail was l 2/5 miles long, and the second trail was 5 times as long as the first trail. Ho

Licemer1 [7]

Answer:

$6 \frac{2}{5} \: miles$

Step-by-step explanation:

$First \: trail = 1 \frac{2}{5} = \frac{7}{5} \: miles \\ \\ second \: trail = 5 \times first \: trail \\ \\ = 5 \times \frac{7}{5} \\ \\ = 7 \: miles \\ \\ total \: length = \frac{7}{5} + 5 \\ \\ = \frac{7 + 25}{5} \\ \\ = \frac{32}{5} \\ \\ = 6 \frac{2}{5} \: miles$

Mrs. Jones buys 7 t shirts and 6 hats for $86. The price of each t shirt is $3 more than the price of each hat. How much does Mr

Maslowich

The price of 1 hat is $ 5 and price of 1 t-shirt is $ 8

<em><u>Solution:</u></em>

Let "s" be the price of 1 shirt

Let "h" be the price of 1 hat

<em><u>Given that Jones buys 7 t-shirts and 6 hats for $86</u></em>

Therefore, we can frame a equation as:

price of 1 shirt x 7 + price of 1 hat x 6 = 86

$s \times 7 + h \times 6 = 86$

7s + 6h = 86 ------ eqn 1

<em><u>Also given that The price of each t shirt is $3 more than the price of each hat</u></em>

price of 1 shirt = 3 + price of 1 hat

s = 3 + h -------- eqn 2

<em><u>Let us solve eqn 1 and eqn 2</u></em>

Substitute eqn 2 in eqn 1

7( 3 + h ) + 6h = 86

21 + 7h + 6h = 86

21 + 13h = 86

13h = 86 - 21

13h = 65

From eqn 2,

s = 3 + h = 3 + 5 = 8

Thus price of 1 hat is $ 5 and price of 1 t-shirt is $ 8
