A town has a population of 90,200 and shrinks at a rate of 2% every year. Which equation represents the town’s population after 7 years
Answer: f(x) = 90,200 (1-.002)^7
Step-by-step explanation:
f(x) = a (1 - r)^t
a - initial amountr - ratet - timef(x) = 90,200 (1-.02)^7
The equation f(7) = 90,200 (1 - 0.02)⁷ represents the town’s population after 7 years.
What is an exponential function?An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.
A town has a population of 90,200 and shrinks at a rate of 2% every year.
As we know the exponential equation for the population as
f(n) = a (1 - r)ⁿ
Where a is the initial population
r is rate
n is years
As per the question, we have
a = 90,200, r = 2/100 = 0.02, and t = 7 years
Substitute the known values in the above equation, and we get
f(7) = 90,200 (1 - 0.02)⁷
This equation represents the town’s population after 7 years.

A test weight is dropped from the top of a fire department
training tower onto a net three feet off the ground. Use - 16t2 for the change

a.) Write an equation to determine the time
it takes for the test weight to drop on the
net.
67 ft
b.) How long does it take before the test
weight is caught by the net? Explain.
Using quadratic function concepts, it is found that:
a) The equation is: 16t² - 64 = 0.
b) It takes 4 seconds before the weight is caught by the net.
What is the quadratic equation for a projectile's height?It is given by:
h(t) = -16t^2 + v(0)t + h(0).
In which:
v(0) is the initial velocity.h(0) is the initial height.Item a:
In this problem, the object starts from rest at a height of 67 ft, hence v(0) = 0 and h(0) = 67.
Then, the equation for the height is given by:
h(t) = -16t^2 + v(0)t + h(0)
h(t) = -16t^2 + 67
It hits the net when h(t) = 3, hence:
3 = -16t^2 + 67
16t² - 64 = 0.
Item b:
16t² = 64
[tex]t = \pm \sqrt{4}[/tex]
t = 4, as time is positive.
It takes 4 seconds before the weight is caught by the net.

In (circle)A, m∠BAD = 110. Find mDE.
Answer: 70
Step-by-step explanation: BAD is 110 degrees and BDE is 180 so do 180 minus 110 and gets you 70 which is DE
Reason:
Central angle BAD is 110 degrees.
This makes angle DAE to be 180-110 = 70 degrees since the two angles are supplementary. They combine to a 180 degree straight angle.
From there, minor arc DE is also 70 degrees. This is because the central angle subtending the arc will be the same measure.

Answer:
PLEASE MARK AS BRAINLIST
we know thatthe equation of the circle is of the formwhere(h,k) is the center of the circler is the radius of the circlein this problem we havesothe center is the point the radius is thereforethe answer isThe radius of the circle is equal to 4units
The required radius of a circle whose equation is (x + 5)² + (y - 3)² = 4² is 4. Option B is correct.
What is a circle?The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by
(x - h)² + (y - k)² = r²
where h, k is the coordinate of the center of the circle on a coordinate plane and r is the radius of the circle.
The equation of the circle is given by:
(x + 5)² + (y - 3)² = 4²
Comparing this equation with the standard form of the equation of a circle:
(x - a)² + (y - b)² = r²
We can see that the center of the circle is at the point (-5, 3), and the radius of the circle is 4 units (which is the same as the constant on the right-hand side of the equation).
Therefore, the radius of the circle is 4 units.
So the answer is (B) 4 units.

The Algebra teachers at Blue Field High School need to buy new textbooks and calculators for the math department. The textbooks cost $105.00 each, and the calculators cost $120.00 each. If the teachers have $4,000 to spend and purchase 25 calculators, how many textbooks can they buy?
Answer: 9 textbooks
Step-by-step explanation:
25 x 120.00 = 3,000
4,000 - 3,000 = 1,000
9 x 105.00 = 945

m = k/m sub in the values given
-4 = k / 17
k = -68
so m = -68/n NOTE: this can also be written as n = -68/m
Answer:
Step-by-step explanation:
Nikki, they wrote the problem in a format that is general
y = k/ x for the given variables m and n then
m = k / n where k is some constant ( konstant)
plug in the given numbers for m and n
-4 =k / 17
solve for k
-4 * 17 = k
-68 = k
now we have a better formula
m = -68 / n ( this is your answer a )
now plug in -136 for m
-136 = -68 / n
solve for n
n = -68 / -136
n = 1/2 ( this is your answer b)

What is the area of the orange rectangle?
Answer:
Well it is 16
Step-by-step explanation:
the rectangle has 2 of the same sides for each side, so 3x2+5x2, a square has all sides equal to each other, so 4x4
So Now we do the easy part|
The rectangle that is grey:
3x2 = 6
5x2 = 10
6+10 =16
The orange square:
4x4 = 16
4+4=8
4+4=8
8+8=16
Therefore both are 16, meaning 16 must be the perimeter for both!

Answer:
e = 10Step-by-step explanation:
In this question we are provided with an equation that is 9e + 4 = -5e + 14 + 13e . And we are asked to find the value of e .
Solution : -
[tex] \longrightarrow \qquad \: 9e + 4 = {-5e} + 14 + { 13e}[/tex]
Step 1 : As there are like terms in right side . So we are solving them and get :
[tex] \longrightarrow \qquad \: 9e + 4 = 14 + 8e[/tex]
Step 2 : Subtracting 4 on both sides :
[tex] \longrightarrow \qquad \: 9e + \cancel{4 }- \cancel{4 }= 14 + 8e - 4[/tex]
Now , cancelling 4 with -4 and subtracting 4 from 14 :
[tex]\longrightarrow \qquad \: 9e = 10 + 8e[/tex]
Step 3 : Subtracting 8e on both sides :
[tex] \longrightarrow \qquad \: {9e } - {8e } =10 + \cancel{ 8e} - \cancel{ 8e}[/tex]
On further calculating , we get :
[tex]\longrightarrow \qquad \: \underline{\boxed{\bold{ \frak{{e = 10}}}}}[/tex]
Therefore , value of e is equal to 10.Verifying : -
We are verifying our answer by substituting value of e in given equation. So ,
9e + 4 = -5e + 14 + 13e9 (10) + 4 = -5 (10) + 14 + 13 (10)90 + 4 = -50 + 14 + 13094 = -50 + 14494 = 94L.H.S = R.H.SHence, Verified.Therefore, our value for e is correct .

What are Trigonometric Functions?Trigonometric functions are the functions which are represented as the ratio of the sides of a right angled triangle.
The three main trigonometric functions are sine, cosine and tangent function.
Sine function of an angle is the ratio of the opposite side to the hypotenuse of the triangle.
Cosine function of an angle is the ratio of the adjacent side to the hypotenuse of the triangle.
Here,
Hypotenuse of the triangle = KJ = 15 inches
LJ = 10 inches is the adjacent side with respect to the angle x.
We can use cosine function here.
cos (x) = LJ / KJ = 10/15
