Darius wants to create a large mural to cover part of his wall. He drew a sketch of his design to
determine the amount of canvas he needs. The area of the design was 0.4 square feet. If the
actual mural will have dimensions 6 times that of the design, how many square feet of canvas
will Darius need?
Model mural::
L*W = 0.3 sq. ft
--------------
Actual mural::
(5L)(5W) = 25*LW = 25*0.3 = 7.5 sq ft.
The notation arcsinx represents the inverse sine function.
• A. True

You are riding the bus to school and you realize it is taking longer because of all the stops you are making. The time it takes to get to school measured in
minutes, is modeled using the function g(x) = x - 3x + 4x - 5, where x is the number of stops the bus makes. If the bus makes 2 stops after you board, how
long does it take you to get to school?
AA. 1 minute
B. 3 minutes
C. 7 minutes
D. 11 minutes
Answer:
-1
Step-by-step explanation:
g(2) = (2) - 3(2) + 4(2) - 5
g(2) = 2 - 6 + 8 - 5
g(2) = 2 - 6 + 3
g(2) = 2 - 3
g(2) = -1

standing to the top of the tree and get 50 degrees. How far away from the tree are you?
Step-by-step explanation:
given :
h = 50 ft
the angle if elevation , a = 50°
find :
the distance , d =?
the answer:
tan a = h/d
d = h /tan a
= 50/ tan 50°
= 50 / 1,19

Answer:
800 bacteria
Step-by-step explanation:
Answer of this question depend upon number of hours at the end of day
Let Take Full Day of 24 hrs
Colby bacteria will doubled 12 times ( doubled once in 2hrs => 24/2 = 12)
Colby bacteria at end of day = 50 * 2¹²
Jaquan bacteria will doubled 8 times ( doubled once in 3hrs => 24/3 = 8)
Let say Jaquan bacteria at start of Day = J
Jaquan bacteria at end of day = J * 2⁸
Equating Both
J * 2⁸ = 50 * 2¹²
=> J = 50 * 2⁴
=> J = 50 * 16
=> J = 800
Jaquan will start with 800 Bacteria

What is the quotient? startfraction 2 m 4 over 8 endfraction divided by startfraction m 2 over 6 endfraction
The Quotients of the given expression (2m + 4) / 8 divided by (m + 2)/6 would be 3/2.
What are the Quotients?Quotients are the number that is obtained by dividing one number by another number.
Dividend ÷ Divisor = Quotients
(2m + 4) / 8 divided by (m + 2)/6
= (2m + 4) / 8 ÷ (m + 2)/6
= (2m + 4)/8 x (6 / (m + 2) )
= (m + 2)/4 x 6/(m + 2)
= 6/4
= 3/2
Thus, the quotients will be 3/2.

a) Write an equation for the growth of bacteria over time.
b) How money bacteria will there be in 5 minutes? 1 hour?
c) How long will it take for the bacteria to reach a population of 10,000?
A) The equation for the growth of bacteria over time is : n(t) = 27( [tex]e^{25t}[/tex])
B) The number of bacteria the would be in 5 minutes 1 hour is :
n(5mins) = 215.055 , n(1) = 1944132282109.422
C) The time it will take for the bacteria to reach a population of 10,000 is : t = 0.237 hours
Determine the Equation, number of bacteria and time takenApplying the mathematical growth and decay modelling
a. n(t) = [tex]n_{0}[/tex] [tex]e^{rt}[/tex]
[tex]n_{0}[/tex] = initial amount of bacterial
[tex]e^{rt}[/tex] = exponent
r = rate
t = time
n(t) = 27( [tex]e^{25t}[/tex])
b. for 5 minutes
converting 5 minutes to hours; we divide by 60 minutes
[tex]\frac{5}{60}[/tex] = 0.083 hour
n(5 mins) = 27( [tex]e^{25t}[/tex])
n(5 mins) = 27( [tex]e^{25 * 0.083}[/tex])
n(5 mins) = 27( [tex]e^{2.075}[/tex])
n(5mins) = 27( 7.965)
n(5mins) = 215.055
For 1 hour we have
n(1) = 27( [tex]e^{25t}[/tex])
n(1) = 27( [tex]e^{25 * 1}[/tex])
n(1) = 27( [tex]e^{25}[/tex])
n(1) = 27 * (72004899337.386)
n(1) = 1944132282109.422
c. How long will it take for the bacteria to reach a population of 10,000?
10000 = 27( [tex]e^{25t}[/tex])
[tex]\frac{10000}{27}[/tex] = ( [tex]e^{25t}[/tex])
370.370 = ( [tex]e^{25t}[/tex])
㏑ (370.370 ) = ㏑ ( [tex]e^{25t}[/tex])
5.915 = 25t

Step-by-step explanation:
First of all we need to label the missing sides ,please check the figure I provided for that :
x = 37 - (10+ 15) = 37 - 25 = 12
z = 10
y = 2 × 10 = 20
The shade does area = area of the whole rectangle − the white area
= 37 × 20 − [ (15×20)÷2 + (10×12)÷2 ]
= 740 − [ 150 + 60 ]

PEMDAS
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:
Parenthesis, Exponents (& Roots), Multiplication, Division, Addition, Subtraction.
First, divide 3 from both sides of the equation:
[tex]\frac{(3x^2)}{3} = \frac{(48)}{3}[/tex]
[tex]x^{2} = \frac{48}{3}\\ \\x^2 = 16[/tex]
Next, isolate the variable, x, by rooting both sides of the equation:
[tex]\sqrt{x^{2} } = \sqrt{16}\\ x = \sqrt{16} = \sqrt{4 * 4}[/tex]
x = ±4
C) ±4 is your answer.

Answer:
173 degrees
Step-by-step explanation:
we know AED + AEB + BEC + CED = 360
AEB = 112
to find BEC, we have B + BCE + BEC = 180 because they form a triangle. so BEC = 180 - B - BCE = 180 - 73 - 79 = 28
to find CED, follow the same steps as BEC: 180 - 37 - 96 = 47
now AED = 360 - AEB - BEC - CED = 360 - 112 - 28 - 47 = 173

Answer: Reflection across the y-axis
Step-by-step explanation:
A reflection over a y-axis means that the original point (x, y) becomes (-x, y)
The original point (-2, 1) should become (-(-2), 1) which becomes just (2, 1).
(2, 1) is the reflected point hence it is a reflection across the y-axis

[tex]-38x+43=-40x-57[/tex]
Answer:
x=-50
Step-by-step explanation:
I used the method of balancing equations:
Add -40x to both sides
-38x+43 + 40x = -40x-57+40x
Simplify:
2x+43 = -57
Subtract 43 from both sides:
2x+43 -43 = -57 -43
Simplify:
2x = -100
Solve for x
2x÷2 = -100÷2
x = -50

Answer:
Solution of equation ( x ) = -50Step-by-step explanation:
In this question we have given an equation that is -38x + 43 = -40x - 57 . And we have to find the solution of this question that means we have to find the value of x .
So let's start our Solution : -
[tex] \hookrightarrow \: -38x+43=-40x-57 [/tex]
Step 1 : Subtracting 43 on both sides :
[tex] \hookrightarrow \: \: - 38x + \cancel{43} - \cancel{43 }= - 40x - 57 - 43[/tex]
On calculating further , We get :
[tex] \hookrightarrow \: - 38x = - 40x - 100[/tex]
Step 2 : Adding 40x on both sides :
[tex] \hookrightarrow \: - 38x + 40x = - \cancel{40x} - 100 + \cancel{40x}[/tex]
On calculating further , We get :
[tex] \hookrightarrow \:2x = - 100[/tex]
Step 3 : Dividing by 2 on both sides :
[tex] \hookrightarrow \: \frac{ \cancel{2}x}{ \cancel{2} } = \cancel \frac{ - 100}{2} [/tex]
On calculating further , We get :
[tex] \hookrightarrow \: \purple{\boxed{\frak{x = - 50}}}[/tex]
Henceforth , value of x is -50 .Verifying : -
Now we're verifying our answer by substituting value of x in given equation . So ,
-38x + 43 = -40x - 57-38 ( -50 ) + 43 = -40 ( -50 ) - 571900 + 43 = 2000 - 571943 = 1943L.H.S = R.H.S Hence, Verified.Therefore , our solution is valid .
