Answer:
Step-by-step explanation:
This can be represented as exponential decreasing function.
y = a(1 - r)t
a = starting amount
r = rate
t = years
y = 1600(1 - .0725)15
= 1600(.9275)15
= 1600(.32337673)
= 517.40
In 15 years, the forest will shrink in size to 517.40 km2
Answer:
idk but try again. i need help with that one too.
Step-by-step explanation:
Answer:
Y=×^2-9
Step-by-step explanation:
(X+0)^2-9
Use the vertex form, y=a(x-h)^2+k
a=1
h=0
k=-9
And because the parabola opens up the vertex is (0,-9)
The distance from the vertex to a focus of the parabola by using the __ 1/4a__ formula:
1/4(1)
1/4
(h,k+p)
(0,-35/4)
Answer:
Step-by-step explanation:
<u>When the line is given in standard form:</u>
- ax + by = c, it has slope of -a/b
<u>Given line:</u>
<u>It has a slope:</u>
A line perpendicular to the given should have a slope m = 1 as negative reciprocal to the given
<u>Let's see which line has the slope of 1:</u>
- 1. m = -(-1)/6 = 1/6 - NO
- 2. m = -4/4 = -1 - NO
- 3. m = -2/4 = -1/2 - NO
- 4. m = -(-2)/2 = 1 - YES
Correct option is D
