The answer is y=-2/3+2 because the line crosses at 2, which is the y-intercept. It goes down two times and runs three times making the slope -2/3.

Threatened monarch butterflies are monitored by measuring the area occupied by overwintering butterflies in Mexico. According to

Pani-rosa [81]

Answer:

14.2 hectares

Step-by-step explanation:

Fund Mexico, monarch butterflies occupied 1.13 hectares one recent winter, and 4.01 hectares the following winter (one year later)

The formula of Geometric growth

(Pt/ Po)^1/t

Where Pt = Size after t years = 4.01 hectares

Po = Initial size = 1.13

t = times = 1

=( 4.01/1.13 )^1/1

= 3.5486725664

Hence, Geometric growth rate = 3.5486725664.

It's size in hectares after another 1 year = Current size in hectares × Geometric growth rate

= 4.01 ×3.5486725664

= 14.230176991 hectares

≈ 14.2

alvin and simon raced a distance of 2.9 x 10^2 kilometers. they need to race 7 times that distance in kilometer. how far must th

dimaraw [331]

The distance in kilometers in scientific notation $2.03 \times 10^3 km$

<h3>Scale factors</h3>

Scale factors are values or constants multiplied with a variable

If Alvin and Simon raced a distance of $2.9 \times 10^2$ kilometers and they need to race 7 times that distance in a kilometer, the distance traveled will be:

Distance travelled = $7(2.9 \times 10^2)$
Distance travelled = $2.03 \times 10^3 km$

Hence the distance in kilometers in scientific notation $2.03 \times 10^3 km$

Answer:

a. L.B. = 20.5

b. U.B. = 21.5

Step-by-step explanation:

Length is measured 21 cm correct to 2 significant figures

a. Lower bound of 21

= 20.5 < 21

= 20.5

b. Upper bound of 21

= 21 < 21.5

= 21.5

The table shows the distance y (in miles) that you travel on a road in x minutes. What type of function best models the data?

evablogger [386]

Answer:

Linear Function

Step-by-step explanation:

Given

The table showing values of x and y

Required

Determine the type of function

To determine the type of function, the table represents;

One will need to determine the table equation.

Start by solving for the slope;

$m = \frac{y_1 - y_2}{x_1 - x_2}$

When x - 0; y = 0 and When x = 80; y = 60.

This gives

$m = \frac{0 - 60}{0 - 80}$

$m = \frac{- 60}{- 80}$

$m = \frac{3}{4}$

The formula is determine as follows;

$y - y_1 = m(x - x_1)$

When x - 0; y = 0; m = 3/4; This gives

$y - 0 = \frac{3}{4}(x - 0)$

$y = \frac{3}{4}(x - 0)$

Open Bracket

$y = \frac{3}{4}x - 0$

$y = \frac{3}{4}x$

The above is an example of a linear equation.

<em>Hence; option B answers the question</em>
