Answer:
25
Step-by-step explanation:
Using the rules of BIDMAS, you first work out the calculation inside the bracket. y-z equals 25-20 which equals 5. then, you work out out the fraction. x=10 so 10/2 equals 5. Then, multiply the value inside the bracket (5) by the outside value(5). This equals 25
Answer:
46 years
Step-by-step explanation:
We have the logistic growth function 
and we want to find the time when the population will reach 20,000, to do it we just need to replace 
with 20,000 and solve for 
:
Divide both sides by 25,000
Multiply both sides by 
and divide them by 0.8
Subtract 1 from both sides
Divide both sides by 8.25
Take natural logarithm to both sides
Divide both sides by -0.076
≈ 46
We can conclude that the population will reach 20,000 after 46 years.
Answer:
Step-by-step explanation:
The equation of a circle is (x-h)^2+(y-k)^2=r^2 where r is the radius of the circle and (h,k) is the coordinates of the center of the circle. We can see that the radius is 3 units and we are given the location of the center as (-3,1) so
(x+3)^2+(y-1)^2=9
Answer:
<h2>m = 2G² + 5</h2>
Step-by-step explanation:
To make m the subject square both sides of the equation
That's
Cross multiply
m - 5 = 2G²
Move 5 to the right side of the equation to make m stand alone
We have the final answer as
<h3>m = 2G² + 5</h3>
Hope this helps you
Answer:
39.91 degrees.
Step-by-step explanation:
Formula
Sin(A)/a = Sin(B) / b
Givens
Solution
Sin(84)/31 = Sin(B)/20
20*Sin(84) / 31 = Sin(B)
Sin(B) = 0.6416
B = 39.91 degrees.
====================
This looks like it is right, but you should check. Let h be the height opposite angle A.
h/20 = sin(39.91)
h = 20*sin(39.91)
h = 12.83
31 has to be longer than that amount (which it is.) So there is one solution.
