The number of the trees that will be left after 10 years will be 2.3 billions.
What is the percent decrease?A rate of change is negative when the output decreases as the input increases or when the output increases as the input decreases.
Given that, the number of trees in a rainforest decreases each month by 0.5%. The forest currently has 2.5 billion trees.
The expression will be:
A = P(1-r)ⁿ
A = final amount
P = initial amount
r = rate
n = time
Therefore,
A = 2500000000(1-00.5)¹⁰
A = 2500000000(0.995)¹⁰
A = 2300000000
Hence, the number of the trees that will be left after 10 years will be 2.3 billions.

Determine the unknown values, R and W, in the figure below.
Answer:
W = 28.63
R = 15.59
Step-by-step explanation:
From the right triangle given in the picture,
By applying sine rule in the triangle,
sin(57°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{24}{W}[/tex]
W = [tex]\frac{24}{\text{sin}(57)}[/tex]
W = 28.63
Similarly, by tangent rule,
tan(57)° = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
1.54 = [tex]\frac{24}{R}[/tex]
R = [tex]\frac{24}{1.54}[/tex]
R = 15.59
Look at this triangle.

In the equation of a straight line, y = mx + c. what does the 'c' represents
Answer:
Equations of straight lines are in the form y = mx + c (m and c are numbers). m is the gradient of the line and c is the y-intercept (where the graph crosses the y-axis).

Answer:
Ivan has 42 blue beads.
Step-by-step explanation:
We need to find how many blue beads Ivan has.
Blue beads = 6 times as many as red beans
b = 6r
r + b = 49
r + (6r) = 49
7r = 49

Find an equation for the perpendicular bisector of the line segment whose end points are (-9,-8) and (3,-2)
Answer:
[tex]y=-2x-11[/tex]
Step-by-step explanation:
Slope of the line segment = [(-8)-(-2)]/[(-9)-3]=-6/-12=1/2
Slope of the perpendicular bisector x slope of line segment = -1
Slope of perpendicular bisector = -2
Mid-point of line segment = ((-9+3)/2, (-8+(-2))/2) = (-3, -5)
The perpendicular bisector passes through the mid-point.
By point-slope form,
[tex]\frac{y-(-5)}{x-(-3)} = -2\\y+5=-2x-6\\y=-2x-11[/tex]
