the y intercept is -3 because its touching (0,-3).

The graph goes right one and down five so the slope is -5

y=mx + b

y= -5x -3

an architect is presenting a scale model of a building she's designed to the planning committee of college the scale of the mode

Naddik [55]

The tall of the actual building will be 216 feet

Step-by-step explanation:

An architect is presenting a scale model of a building she's designed

to the planning committee of college

1. The scale of the model is 1 inch = 18 feet

2. The tallest wall in the model is 12 inches

3. We need to know how tall the actual building will be

Let us used the ratio method

∵ The scale of the model is 1 inch represents 18 feet

∵ The tallest wall in the model is 12 inch

→ Model(in) : Actual(ft)

→ 1 : 18

→ 12 : h

- By using cross multiplication

∴ 1 × h = 12 × 18

∴ h = 216 feet

∴ The actual height is 216 feet

The tall of the actual building will be 216 feet

At the beginning of an environmental study, a forest covered an area of 1500 km2 . Since then, this area has decreased by 9.8% e

fredd [130]

Answer:

$A(t)=(0.902)^t \cdot 1500$ $[km^2]$

Step-by-step explanation:

In this problem, the initial area of the forest at time t = 0 is

$A_0 = 1500 km^2$

After every year, the area of the forest decreases by 9.8%: this means that the area of the forest every year is (100%-9.8%=90.2%) of the area of the previous year.

So for instance, after 1 year, the area is

$A_1 = A_0 \cdot \frac{90.2}{100}=0.902 A_0$

After 2 years,

$A_2=0.902 A_1 = 0.902(0.902A_0)=(0.902)^2 A_0$

And so on. So, after t years, the area of the forest will be

$A(t)=(0.902)^t A_0$

And by substituting the value of A0, we can find an explicit expression:

$A(t)=(0.902)^t \cdot 1500$ $[km^2]$
