Step-by-step explanation:
The function B(t) = 1872(0.83)[tex].^t[/tex] represents the annual population of bees in a county park, the decline rate is 17%.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depend on any other variable for its value while a dependent variable is a variable that depends on other variable.
The decline rate will be calculated as below:-
An exponential function is in the form:
y = abˣ
Where a is the initial value and b is the multiplication factor.
From the function :
b = 0.83
The decline rate will be calculated as,
Decline rate = 1 - 0.83 = 0.17 x 100 = 17%
The function B(t) = 1872(0.83)[tex].^t[/tex] represents the annual population of bees in a county park, the decline rate is 17%.

Step-by-step explanation:
Miss Violet is buying granola bars for her students. She already has 16 granola bars in her desk and needs a total of 100 bars. They are sold in packs of 12. Write an equation to show how many more boxes of granola bars she needs.
16 – 12x = 100
16 – 12x = 100
16x + 12 = 100
16x + 12 = 100
16 + 12x = 100
16 + 12x = 100
12x – 16 = 100
12x – 16 = 100
Answer:
100 - 16 = 84, and 84 divided by 12 is 7. She needs to buy 7 more boxes of granola bars for her students.
Step-by-step explanation:
Answer:
She need 7
Step-by-step explanation:
12x7=84
Then add 16 to 84 to get 100
Which solution to the equation startfraction 3 over a 2 endfraction startfraction 2 over a endfraction = startfraction 4 a minus 4 over a squared minus 4 endfraction is extraneous?
The solution of the rational equation [tex]\frac{3}{a + 2} * \frac{2}{a} = \frac{4 a - 4 }{a^2 - 4}[/tex] is a = 3
How to determine the solution?The equation is given as:
[tex]\frac{3}{a + 2} * \frac{2}{a} = \frac{4 a - 4 }{a^2 - 4}[/tex]
Express a^2 - 4 as a difference of two squares
[tex]\frac{3}{a + 2} * \frac{2}{a} = \frac{4 a - 4 }{(a + 2)(a - 2)}[/tex]
Cancel out the common terms
[tex]\frac{3}{} * \frac{2}{a} = \frac{4 a - 4 }{a - 2}[/tex]
Factor out 2 from 4a - 4
[tex]\frac{3}{} * \frac{2}{a} = \frac{2(a - 2) }{a - 2}[/tex]
Evaluate the quotient
[tex]\frac{3}{} * \frac{2}{a} = 2[/tex]
Divide both sides by 2
[tex]\frac{3}{1} * \frac{1}{a} = 1[/tex]
Cross multiply
a = 3
Hence, the solution of the equation [tex]\frac{3}{a + 2} * \frac{2}{a} = \frac{4 a - 4 }{a^2 - 4}[/tex] is 3

PLEASE ASAP we need to turn in in 20 mins
Answer:
14 units^2
Step-by-step explanation:
Hey there!
In order to find the area of this triangle, we need to find the base and height of the triangle
the base of the triangle is 7 units long and the height of the triangle is 4 units high
Formula for area of triangle: Base x Height x 1/2
7 x 4 x 1/2 --> 28 x 1/2 --> 14
So, the area of this triangle is 14
Now the question is asking to find the area by forming a parallelogram
All you have to do for this is duplicate that same triangle, and mirror it upside down
Then all you would have to do is find the Base and the Height and multiply them together

BD^2 = 36 + 64 = 100
BD = 10
use sine law
sin (29) / BD = sin (x)/ DC
sin (29)/ 10 = sin x/ 13
sin x = 13 sin (29)/ 10
First solve for BD:
a² + b² = c²6² + 8² = BD²BD² = 36 + 64BD² = 100BD = √100BD = 10Then use sine rule:
sin(A)/a = sin(B)/binsert values
sin(29)/10 = sin(x)/13exchange sides
sin(x) = 13sin(29)/10simplify
sin(x) = 6.302525/10sin(x) = 0.63change side

QR is the radius of R and PQ is the tangent to R. Find the value of x.
Answer:

Step-by-step explanation:
We know that PRQ is a right triangle, so we use the pythagorean theorem to solve the problem. The theorem states that a^2 + b^2 = c^2. Let's assume that the length of RP is c, the length of PQ is a and x is b. We plug the lengths into the equation and solve it:

Answer:
b = 17
Step-by-step explanation:
The correct equation is 3b - 6 = 45. You get this by saying the books (b) are 3 dollars each (3b) and you are getting a discount of 6 dollars off (- 6). The total after the discount is 45 dollars. You know have to solve this equation for b (the number of books) to get the answer. When you solve this equation, you get b = 17.
Answer:
3b - 6 = 45 and b = 17
Step-by-step explanation:
3b - 6 = 45 is your equation you get
3b is how many books you bought and the price multiplied by one another, then subtracting 6 gives you the discounted price which is 45
3b - 6 = 45
+6 +6
3b = 51
/3 /3
b = 17
a book costs 17 dollars.
so b = 17

The equation of the line which is plotted on the graph and passes from the points (2,5) and (-2,-3) is y=2x-6.
What is the equation of line?The equation of the line is the way of representation of a line in the equation form.
The equitation of the lines represents the line by the set of points on which the line lies or passes through in the coordinate system.
The formula to find equation of line is,
(y-y₁)={(y₂-y₁)/(x₂-x₁)}(x-x₁)
Here, x and y are the coordinate and subscript (1,2) used for the first and second point.
The points from which the line passes through are (2,5) and (-2,-3). Put the values,
(y-y₁)={(y₂-y₁)/(x₂-x₁)}(x-x₁)
(y-(-2))={(-3-5)/(-2-2)}(x-2)
y+2={-8/-4}(x-2)
y+2=2(x-2)
y+2=2x-4
y=2x-4-2
y=2x-6

the answer is : 50,666.64
Using an exponential function, it is found that she can be expected to have $50,666.64 in the fund in 7 years.
What is an exponential function?An increasing exponential function is modeled by:
[tex]A(t) = A(0)(1 + r)^t[/tex]
In which:
A(0) is the initial value.r is the decay rate, as a decimal.In this problem, we have that the initial amount and the growth rate are given, respectively, by:
A(0) = 26000.r = 0.1.Hence the amount after t years is given by:
[tex]A(t) = 26000(1.1)^t[/tex]

Ravi buys lunch at a restaurant.
An 8% sales tax is added, and he tips the waiter 20% of the cost of the food.
Ravi pays a total of $17.92 for his lunch, including tax and tip.
What is the price of Ravi's lunch, before tax and tip?
The price of Ravi's lunch, before tax and tip was added to the total cost of the meal is $13.19.
What is the price of the lunch?Both the tax and the tip paid would increase the cost of the meal. Thus, their dollar value has to be subtracted from the total amount he pays.
Value of the lunch after the tip has been removed = (1 - 0.2) x 17.92 = $14.34
Value of the lunch after the tax has been removed = (1 - 0.08) x $14.34 = $13.19
