Answer:
y=5(1.05)^t=5% rate of growth
f(t)=50(0.95)^t=5% rate of decay
g(t)=50(1.5)^t=50% rate of growth
y=5(.5)^5=50% rate of decay
Step-by-step explanation:
y=5(1.05)^t= 1+x=1.05. x=0.05. 0.05= 5%, 5% rate of growth,
f(t)=50(0.95)^t=1-x=0.95, x=-0.05=-5%=5% rate of decay
g(t)=50(1.5)^t=1+x=1.5, x=0.5=50%, 50% rate of growth
y=5(.5)^5=1+x=0.5, x=-0.5=50%, 50% rate of decay

The correct matching of the functions y = 5 · (1.05)ⁿ, y = 50 · (0.95)ⁿ, y = 50 · (1.5)ⁿ, and y = 5 · (0.05)ⁿ will be growth rate is 5%, the decay rate is 5%, the growth rate is 50%, and the decay rate is 50%, respectively.
What is an exponent?Consider the function:
y = a (1 ± r)ˣ
Where x is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.
If there is a plus sign, then there is exponential growth happening by r fraction or 100r %
If there is a minus sign, then there is exponential decay happening by r fraction or 100r %
The functions are given as,
y = 5 · (1.05)ⁿ
y = 5 · (1 + 0.05)ⁿ
The growth rate is 5%.
y = 50 · (0.95)ⁿ
y = 50 · (1 - 0.05)ⁿ
The decay rate is 5%.
y = 50 · (1.5)ⁿ
y = 50 · (1 + 0.5)ⁿ
The growth rate is 50%.
y = 5 · (0.05)ⁿ
y = 5 · (1 - 0.5)ⁿ
The decay rate is 50%.
The correct matching of the functions y = 5 · (1.05)ⁿ, y = 50 · (0.95)ⁿ, y = 50 · (1.5)ⁿ, and y = 5 · (0.05)ⁿ will be growth rate is 5%, the decay rate is 5%, the growth rate is 50%, and the decay rate is 50%, respectively.

Mr. Torres spent $40.00 to buy 18 pounds of ground beef and chicken for a family to cook out. If the price of ground beef was $4.00 per pound and the chicken was $2.00 per pound, how many pounds of each did he buy?
Answer:
They bought 2 pounds of ground beef and 16 pounds of ground chicken.
Step-by-step explanation:
Let b be the beef, and c be the chicken:
b + c = 18, the pounds of beef and the pounds of chicken added equal 18 pounds
4b + 2c = 40, the beef costs 4 dollars per pound and the chicken costs 2 dollars per pound. They add up to 40 dollars total.
Use the equation b + c = 18 and subtract c from both sides to get b = 18 - c. We replace this equation with b in 4b + 2c = 40 to get 4(18 - c) + 2c = 40 because b is 18 - c.
Now we solve for c:
4(18 - c) + 2c = 40
Simplify:
72 - 4c + 2c = 40
Combine Like Terms:
72 - 2c = 40
subtract 72 from both sides:
-2c = -32
Divide Both Sides by 2:
-c = -16
Make the Equation Positive:
c = 16
Okay cool, now we know that they bought 16 pounds of chicken, to find out how much beef the bought, replace c by 16 in b + c = 18 to get b + 16 = 18
b + 16 = 18
Subtract 16 from both sides:
b = 2, they bought 2 pounds of beef
To check, replace c with 16 and b with 2 in 4b + 2c = 40 to get
4(2) + 2(16) = 40
Multiply:
8 + 32 = 40
40 = 40
The equation is true

PLEASE HELP ANSWER ASAP
Answer:
x = 20
Step-by-step explanation:
Use Pythagorean Theorem to solve for x:
a^2 + b^2 = c^2
Plug in given values if a = 12, b = 16, and c = x (x is hypotenuse)
12^2 + 16^2 = x^2
(12*12) + (16*16) = x^2
144 + 256 = x^2
400 = x^2
Take square root of both sides to solve for x
sqrt(400) = sqrt(x^2)
20 = x or x = 20

The radius of a circle is 3 feet. What is the circumference?
Circumference = 2 * pie * radius
Geometry
Answer:
19 feets
Step-by-step explanation:
Given that , the radius of the circle is 3 feet . We need to find the circumference.
We know that the circumference of circle is 2πr . So ,=> C = 2 π r
=> C = 2 × 22/7 × 3ft
=> C = 18.84 ≈ 19 ft
Hence the circumference of the circle is 19 feet.Answer:
B
Step-by-step explanation:
circumference = 2πr
3.4x 2 x 3 = 18.84

What is the value of x and the measure of ∠LNM, respectively?
A. x = 25 ; ∠LNM = 155
B. x = 155 ; ∠LNM = 25
C. x = 45 ; ∠LNM = 135
D. x = 135 ; ∠LNM = 45
Pls dont put nonsense answer thank you
Linear pair of angles are of 180°. So,
45°+3x = 180°
=> 3x = 180°-45°
=> 3x = 135°
=> x = 135°/3
=> x = 45°
Answer:
Option C: x = 45, ∠LNM = 135
Step-by-step explanation:
Both the angles are supplementary which means they both add up to a straight angle or 180°;
45 + 3x = 180
=> First subtract 45 on each side of "="
3x = 135
=> Now divide both sides of "=" by 3
x = 45Now to find measure of angle LNM, substitute in 45 for x
3x = ∠LNM
3(45) = ∠LNM
135 = ∠LNMHope this helps!
