The area of a wetland is 10,000 acres. A biologist predicts that the area of the wetland will change according to the equation y equals 10000 left-parenthesis 0.65 right-parenthesis Superscript x Baseline, where y is the area of the wetland after x years. Based on the biologist's prediction, what will the area of the wetland be in 2 years?
Answer:
4,225 acresStep-by-step explanation:
If a biologist predicts that the area of the wetland will change according to the equation [tex]y = 10,000(0.65)^{x}[/tex] where;
y is the area of the wetland after x years
In order to determine the area of the wetland in 2 years based on the biologist prediction, we will substitute the value of x = 2 into the modeled equation as shown;
[tex]y = 10,000(0.65)^{2}\\y = 10,000 * 0.4225\\y = 4225[/tex]
The area of the wetland in 2 years based on the biologist prediction will be 4225 acres

-5*(-6)=
-27 divided by 9=
Answer:
-5*(-6) = 30
-27/9 = -3
Step-by-step explanation:
We know a negative times a negative is a positive, a positive times a positive is a positive, and a negative times a negative is a positive. This rule goes the same for division.
Using that rule -5*(-6) = 30. Which is a negative times a negative = positive.
-27/9 = -3 Which is a negative divided by positive = negative

(4 + 2)
ANSWER: 100=5*6
100=30
HOPE IT HELPS!
Answer:
x = 3 1/3
Step-by-step explanation:
Let's go over the order of operations.
P: Parentheses
E: Exponents
M/D: Multiplication/division (in order of appearance)
A/S: Addition/Subtraction (in order of appearance)
100 = 5*(4 + 2)
Since there are values in parentheses, solve those first: 100 .= 5x(6).
Next, multiply 5x by 6. 100 = 30x.
Finally, divide each side by 30 to find the value of x. 3 1/3 = x
Therefore, the value of x is 3 1/3.
(Note: this is assuming the term "x" is a variable, and not the multiplication sign, *.)

Answer:
The age of the car in years is the independent variable
The average miles is the dependent variable
Step-by-step explanation:
Typically, the age of the car will have an affect on the number of miles per gallon. However, the number of miles per gallon will not make it gain or lose more years, so the age is independent because it does not depend on another variable.
Hope this makes sense :)
Find the value of y that makes the equation 2y = 12 – 5x true when x = -2.
A. 1
B. 2
C. 11
D. 22
Answer:
C 11
Step-by-step explanation:
2y = 12 – 5x
Let x = -2
2y = 12 - 5(-2)
2y = 12 +10
2y = 22
Divide by 2
2y/2 = 22/2
y = 11

This is a perfect square trinomial in the form a^2 - 2ab + b^2 = (a-b)^2. In this case, a = x and b = -3.
Another way you can look at it is to ask yourself "what two numbers multiply to 9 (last term) and add to -6 (middle coefficient)?". Those two numbers are -3 and -3
-3 plus -3 = -6
-3 times -3 = 9
So this is why x^2-6x+9 = (x-3)(x-3)
We can expand (x-3)(x-3) back out to get x^2-6x+9 again using the FOIL rule, distributive property, or the box method.
Answer:
C. (x-3)(x-3)
Step-by-step explanation:
x² - 6x + 9 = 0
x² - 3x - 3x + 9 = 0
x(x - 3) - 3(x - 3) = 0
(x - 3) (x - 3) = 0

prove that (tan²y) (cos²y) + 1/sec²y = 1
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
tan x = [tex]\frac{sinx}{cosx}[/tex] , sec x = [tex]\frac{1}{cosx}[/tex] , sin²x + cos²x = 1
Consider the left side
tan²y × cos²y + [tex]\frac{1}{sec^2y}[/tex]
= [tex]\frac{sin^2y}{cos^2y}[/tex] × cos²y + [tex]\frac{1}{\frac{1}{cos^2y} }[/tex] ← cancel cos²y in the product
= sin²y + cos²y
= 1
= right side ⇒ proven
Step-by-step explanation:
[tex] (\tan^2y) (\cos^2y) +\frac{1}{\sec^2y} = 1\\
LHS
= (\tan^2y) (\cos^2y) +\frac{1}{\sec^2y} \\\\
\frac{\sin^2y}{\cos^2y}\times \cos^2 y + \cos^2 y \\\\
= \sin^2y + \cos^2 y \\\\
= 1\\\\
= RHS\\\\
\purple {\boxed {\bold {\therefore (\tan^2y) (\cos^2y) +\frac{1}{\sec^2y} = 1}}} \\[/tex]

Use formula A^2+B^2=C^2
Answer:
∠ A ≈ 24°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin A = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{MR}{AR}[/tex] = [tex]\frac{6}{15}[/tex] , thus
A = [tex]sin^{-1}[/tex] ([tex]\frac{6}{15}[/tex] ) ≈ 24° ( to the nearest degree )

A telescope costs $98. It is on sale for 35% off. What is the cost of the telescope after the discount?
Answer:
To solve this equation first we need to find out how much is 35% of $98.
The percentage of a number is found by multiplying the percentage by the number:
35% x $98 = $34.3
So the 35% off the telescope equals a discount of $34.30.
Now let’s find the price after the discount.
We need to subtract the discount price from the original price:
$98 - $34.30 = $63.70
So we know that the price of the telescope after the discount is $63.70

Answer:
Yes there are more 3-digit numbers that can be divided or not divided by 4, 7, or 9
Step-by-step explanation:
Any real number can be divided by those numbers but you may get decimals as well.
There are less 3-digit real numbers that can be divided by at least one of the numbers 4, 7, or 9. Therefore, it's false.
How to compute the number?It should be noted that for a number to be divisible by 9 and 7, it has to be divisible by 63. Therefore, we have all the three digit multiple of 63.
In this case, there are less 3-digit real numbers that can be divided by at least one of the numbers 4, 7, or 9.
