Answer:
4L-12
Step-by-step explanation:
let's assume the length = L
then the width of the rectangle is L - 6
perimeter = 2× (a+b)
where "a" and "b" are the length and the width of the rectangle.
so perimeter = 2× (L + L - 6)
2 × ( 2L - 6)
4L - 12
A bacteria population is growing exponentially with a growth factor of 1/6 each hour. By what growth factor does the population change each half hour? Select all that apply
Using exponential function concepts, it is found that the change of the growth factor of the population each half hour is given by:
b. [tex]\sqrt{\frac{1}{6}}[/tex]
e. [tex]\left(\frac{1}{6}\right)^{0.5}[/tex]
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, the growth factor of 1/6 each hour, hence, [tex]r = \frac{1}{6}[/tex], and:
[tex]A(t) = A(0)(1 + \frac{1}{6})^t[/tex]
For each half-hour, t = 0.5, hence the growth factor is of:
[tex]\left(\frac{1}{6}\right)^{0.5} = \sqrt{\frac{1}{6}}[/tex]
Hence, options b and e are correct.

Explanation:
Start at a point like (0,2) which is on the blue f(x) line.
Move upward until you reach the red g(x) line. You should move up 3 units. Every point on f(x) follows the same pattern to land on a corresponding point on g(x). Therefore, this moves the entire blue line up 3 units.
This leads to k = 3
So g(x) = f(x) + 3

|x+1|=|2x-6|
Answer:
x = 5, and/or x= - 7/3
Step-by-step explanation:
|x+1|=|2x+6|
We know eitherx+1=2x+6orx+1=−(2x+6)
x+1=2x+6(Possibility 1)
x+1−2x=2x+6−2x(Subtract 2x from both sides)
−x+1=6
−x+1−1=6−1 (Subtract 1 from both sides)
−x=5
(Divide both sides by -1)
x=−5
x+1=−(2x+6)(Possibility 2)
x+1=−2x−6(Simplify both sides of the equation)
x+1+2x=−2x−6+2x(Add 2x to both sides)
3x+1=−6
3x+1−1=−6−1(Subtract 1 from both sides)
3x=−7
Divide both sides by 3
x= −7 / 3

x=−5(Works in original equation)

Answer:
(E) 72 w^2 is the answer
Step-by-step explanation:
outer square area is 81 w^2
inner square area is 9 w^2
subtracting outer - inner we can get the shaded area
so 81 -9= 72w^2
Answer:
E. 72w²
Step-by-step explain:
Area I = a × a= 9w × 9w
= 81w²
Area II = a × a= 3w × 3w
= 9w²
Shaded area = Area I - area II= 81w² - 9w²
= 72w²

Point X is the location of and it is an irrational number.
Point Y is the location of 3.16. and it is a rational number
Point Z is the location of v10, and it is a rational number.
Answer:
the second answer is right
Step-by-step explanation:
while it is true that W=25/8, the definition itself (25/8) makes it a rational number (= a ratio of 2 integer numbers). so, in total, the first answer is therefore wrong.
X=pi, and pi is a typical example of an irrational number. so, this second answer is correct.
sqrt(10) < 3.16666666666...
so, Y=sqrt(10) and not 3.166666666..., so the third answer is already wrong there.
and consequently, Z=3.166666... and not sqrt(10), so the fourth answer is therefore also wrong.

g(-2) + g(2) = 22
Step-by-step explanation:
For x = -2, g(x) = x^2 - 3x
or
g(-2) = (-2)^2 - 3(-2) = 4 + 6 = 10
For x = 2, g(x) = 12, therefore
g(-2) + g(2) = 10 + 12 = 22

Answer:
s = 44.5 m
Step-by-step explanation:
The radius of the circle, r = 17 m
Central angle, [tex]\theta=\dfrac{5\pi}{6}\ rad[/tex]
We need to find the length of the arc. Let the length of the arc is s.
[tex]s=r\theta\\\\=17\times \dfrac{5\pi}{6}\\\\s=44.5\ m[/tex]
So, the length of the arc is equal to 44.5 m.

If the producer in a food chain has 1000 kcal of energy available, how much energy would each of the consumers have?
Answer:
Primary consumer = 100kcal
Secondary consumer = 10kcal
Tertiary consumer = 1kcal
Step-by-step explanation:
In a food chain, transfer of energy occurs when one organism feeds on another organism. However, only 10% of energy is transferred from one organism to another because energy is lost as heat when the organisms perform metabolism.
In a typical food chain consisting of a producer, a primary (1st), secondary (2nd) and tertiary (3rd) consumer, if there are 1000 kcal of energy available in the producer, then:
- Primary consumer will obtain; 10% of 1000Kcal
10/100 × 1000
Primary consumer = 100kcal of energy.
- Secondary consumer will obtain as follows; 10% of 100kcal available energy
= 10/100 × 100
Secondary consumer = 10Kcal of energy.
- Tertiary consumer will obtain as follows; 10% of 10Kcal of available energy.
= 10/100 × 10
Tertiary consumer = 1 kcal of energy.

Roy made a pizza that is 12 inches in diameter. He knows he can eat about 84.8 in, at what angle should Roy cut the pizza in radians? Round your answer to the tenths place.
Answer:
Cutting angle in radian θ = 3π / 2
Step-by-step explanation:
Given:
Diameter of pizza = 12 inch
He can eat = 84.8 inch²
Find:
Cutting angle in radian
Computation:
Radius of pizza = Diameter of pizza / 2
Radius of pizza = 12 / 2
Radius of pizza = 6 inch
Area of sector = [θ/360][πr²]
Area of sector = [θ/360][(π)(6)²]
84.8 = [θ/360][(π)(36)]
θ = 270°
θ = 270[π/180]
θ = 27π / 18
Cutting angle in radian θ = 3π / 2
