Two years ago, there were 30 foxes in a forest. this year, there are 40 foxes in the forest. what is the annual percent growth for the foxes?
9514 1404 393
Answer:
about 15.5%
Step-by-step explanation:
The number of foxes in the forest can be modeled by the exponential equation ...
f = a·b^t
where a is the initial number, and b is the growth factor per year for t years. The growth factor is 1 more than the growth rate (r), so we can put numbers in this formula to get ...
40 = 30·(1 +r)^2
4/3 = (1 +r)^2 . . . . . . divide by 30
1 +r = √(4/3) . . . . . . take the square root
r = √(4/3) -1 ≈ 0.1547 ≈ 15.5%
The annual percentage growth in the fox population is about 15.5%.
For a science project, Levan launches a rocket from ground level directly upward at 29.4 meters per second. As the rocket flies, its height in meters above the ground can be modeled as a function of time
by the equation s(t) = -4.96 +29.4t, where t represents the number of seconds after launch.
Use the point tool to plot the points on the grid that best represent
• when Levan launches the rocket
• the rocket at its highest point and
. when the rocket lands on the ground

Convert. 2/3and 4/6 into like fraction
Answer:
Answer given below
Step-by-step explanation:
When we calculate the LCM, you get it as 6.
So both the fractions should have a denominator 6.
For that, in 2/3 we should multiply both numerator and denominator with 2 so that denominator becomes 6.
When we convert to like fraction, 2/3 becomes 4/6.
Now both the fractions have common denominator

Lorenzo has 4 packages of granola bars.
Each package has 10 bars.
He eats one bar from each package.
Which equation shows how Lorenzo can correctly find the total number of granola bars remaining?
4 × 10 – 4 = 36 granola bars
4 × 10 × 1 = 40 granola bars
4 × 10 + 4 = 44 granola bars
4 + 10 – 4 = 10 granola bars
Answer:
A. 4 x 10 - 4 = 36
Step-by-step explanation:
Ten bars are in a package and there are 4 packages
1 bar is eaten from the 4 packages
40 - (1 x 4) =
40 - 4 =

Find the value of X.
9514 1404 393
Answer:
x = 6
Step-by-step explanation:
Angles AFB and CFE are vertical angles, so have the same measure. That means arc AB has the same measure of arc CE. The latter arc is 27° more than arc DE, which is 90°. So, we have ...
arc AB = arc CE
21x -9 = 90 +27
21x = 126 . . . . . . add 9, collect terms
x = 6 . . . . . . . divide by 21

Answer:
maybe B . . . it is the closest
Step-by-step explanation:
There are 180/π degrees in a radian.

11π/8 radians = (11π/8)(180°/π) = (11/8)(180°) = 247.5°
In the diagram below, O is circumscribed about quadrilateral ABCD. What is the value of x?
Answer:
50°
Step-by-step explanation:
In an inscribed quadrilateral, the opposite angles are supplementary (angle sum = 180).
2x + 80 = 180
2x = 100
x = 50
The value of x of O is circumscribed about quadrilateral ABCD is 50degrees
Circle geometryAccording to the circle geometry given, the sum of the opposite sides of the quadrilateral is 180 degrees.
Setting up the required equation;
2x + 80 = 180
2x = 180 - 80
2x = 100
Divide btoh sides by 2
2x/2 = 100/2
x =50
Hence the value of x of O is circumscribed about quadrilateral ABCD is 50degrees

9514 1404 393
Answer:
A. 15.250
Step-by-step explanation:
The applicable trig function is the cosine function:
Cos = Adjacent/Hypotenuse
cos(57°) = y/28
y = 28×cos(57°) ≈ 15.24989
y ≈ 15.250 . . . . matches choice A
_____
Additional comment
From your knowledge of "special" triangles, you know that y would be 14 if the angle were 60°. Of course, the length must be shorter than 28, so answer choices B and C are immediately eliminated. The fact that the length is closer to half of 28 than it is to 28 makes choice A look like a pretty good guess.
