Assuming the triangle adds up to 180°, x = 55 because 55 + 5 = 60. 60 x 3 = 180

In order for the table below to show exponential decay, what must the value of d be in the table below?

Eduardwww [97]

Let x represent the domain
Let y represent the range.

Assume that y =a*b⁻ˣ

Set x=0:
a*b⁰ = 32
a = 32

Set x=1:
32*b⁻¹ = 24
32 = 24b
b = 32/24

Set x=2:
d = 32*(32/24)⁻²
= 32*(24/32)²
= (32*24*24)/(32*32) = 24²/32 = 576/32
= 18

Answer: 18

The number of species of coastal dune plants in australia decreases as the latitude, in °s, increases. There are 34 species at 1

Bas_tet [7]

We have been given that the number of species of coastal dune plants in Australia decreases as the latitude, in °s, increases.

Further we know that there are 34 species at 11°s and 26 species at 44°s.

We can express the given information at two ordered pairs as shown below:

$(n,l)=(11,34)\text{ and }(n,l)=(44,26)$

Let us find slope of the line through these points:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{26-34}{44-11}=\frac{-8}{33}=-0.2424$

Therefore, we can write the equation of line in slope intercept form as:

$n=-0.2424l+b$

Where b is the y intercept, and we can find its value using one of the two points.

$34=-0.2424(11)+b\\34=-2.67+b\\b=34+2.67=36.67$

Therefore, the required equation of the linear function is:

$n=-0.2424l+36.67$

Suppose the first term of a geometric sequence is multiplied by a nonzero constant, c. What happens to the following terms in th

ratelena [41]

The next terms in the sequence will be multiplied by c, but the common ratio is still the same

example :

S = [1(3)^4 - 1]/ [3-1] = 80/2 - 40

Hope this helps
