The value of the evaluation of logarithm e^in4 is 4
How to determine the logarithmGiven the expression as;
e^in4
To put in logarithmic form, equate to the power of the "Lin,ln value"
Now, let's equate it to the value of the exponential
e^in4 = 4
We have that'
[tex]loge x = loge 4[/tex]; this is the logarithmic form of the expression but we need to find the value of 'x'
To find the value, let's cancel out the like variables, we have

5. If 15 men can finish a work in 16 days in how many days will 8 men can finish the same work? a. 15 b. 20 c. 30 d. 42
Answer:
C. 30
Step-by-step explanation:
15 men do work in 16 days
This means that 7.5 men (15/2) would do that same work in 32 days (16x2).
If the number of men increase, the amount of days decrease.
8 men would do that work in 30 days
8 men > 7.5 men
30 days < 32 days
Answer:
Option c.
Step-by-step explanation:
It is an inverse proportion, fewer workers more days to finish the job.
15 -----16
8 ----- x
x = (16)(15)/8 = 240/8 = 30 days

Target Costing
Instant Image Inc. manufactures color laser printers. Model J20 presently sells for $460 and has a product cost of $230, as follows:
Direct materials $175
Direct labor 40
Factory overhead 15
Total $230
It is estimated that the competitive selling price for color laser printers of this type will drop to $400 next year. Instant Image has established a target cost to maintain its historical markup percentage on product cost. Engineers have provided the following cost-reduction ideas:
Purchase a plastic printer cover with snap-on assembly, rather than with screws. This will reduce the amount of direct labor by 15 minutes per unit.
Add an inspection step that will add six minutes per unit of direct labor but reduce the materials cost by $20 per unit.
Decrease the cycle time of the injection molding machine from four minutes to three minutes per part. Forty percent of the direct labor and 48% of the factory overhead are related to running injection molding machines.
The direct labor rate is $30 per hour.

b. Determine the required cost reduction.

2. Additional inspection $fill in the blank 4

3. Injection molding productivity improvement $fill in the blank 5

The target cost for Model J20 is $2000.
The required cost reduction is $30.
The total saving will be $30.3.
How to compute the cost?The target cost will be:
= Sales price - (100% × Target cost)
= 400 - (100% × Y)
Y + Y = 400
2Y = 400
Y = 400/2 = 200
Target cost = $200
Therefore, the target cost is $200.
The required cost reduction will be:
= $230 - $200
= $30
The required cost reduction is $30.
The three engineering improvements together will be:
Direct labor reduction = 7.5
Additional inspection = 17
Injection molding = 5.8
Total savings = 30.3

Find the length indicated
Find SR (image)
Answer:
SR = 5
Step-by-step explanation:
We know that the two lines are equal to each other and thus TS + SR = 13
So, we can simply set the two equations of the first line equal to 13:
x + 2 + 2x - 7 = 13
3x - 5 = 13
3x = 18
x = 6
Now we plug in 6 for x in the SR equation:

The spread of the disease will take a time 100 days to reach 2,500 infected people.
How to find the number of infected people at a certain time
In this problem we have a radical equation that represents the number of infected people as a function of time, we are suppose to find the time when that number will be 2,500 by algebra properties: (N = 2,500)
2,500 = 250 · √t
√t = 2,500 / 250

What are Asymptotes?An asymptote is a line that a curve approaches but never touches. A line where the graph of a function converges is known as an asymptote. When graphing functions, asymptotes are typically not required
There are 3 types of asymptotes
Horizontal asymptote (HA) - It is a horizontal line and hence its equation is of the form y = k. Horizontal Asymptote is when the function f(x) is tending to zero
Vertical asymptote (VA) - It is a vertical line and hence its equation is of the form x = k. Vertical asymptotes are defined when the denominator of a rational function tends to zero
Slanting asymptote (Oblique asymptote) - It is a slanting line and hence its equation is of the form y = mx + b
Given data ,
Let the function be denoted as f ( x )
Now , the value of f ( x ) is
f ( x ) = 2ˣ be equation (1)
The y-intercept of the function is when x = 0
So , when x = 0
f ( 0 ) = 2⁰
f ( 0 ) = 1
So , the y-intercept of the function is at ( 0 , 4 )
And , when the function f ( x ) is tending to zero , the horizontal asymptote is y = 0
Therefore , the horizontal asymptote is y = 0
The domain of the exponential function is { -∞ < x < ∞ }
Hence , the horizontal asymptote of the function f ( x ) = 2ˣ is y = 0

Answer:
279/1640
Step-by-step explanation:
The relations between the various trig functions can be used to find the necessary function values.
Other trig functionsSolving for cos(θ), we have ...
41 cos(θ) = 9
cos(θ) = 9/41 . . . . . divide by 41
The Pythagorean relation tells you ...
sin²(θ) +cos²(θ) = 1 ⇒ sin(θ) = √(1 -cos²(θ))
sin(θ) = √(1 -(9/41)²) = (√(41² -9²))/41 = 40/41
The tangent relation is ...
tan(θ) = sin(θ)/cos(θ) = (40/41)/(9/41) = 40/9
Expression value
The value of the given expression is ...
(sin(θ) -cos(θ))/tan(θ) = (40/41 -9/41)/(40/9) = (31/41)(9/40) = 279/1640

what base could be written in the blank to make the exponential function model 15% decay ? y= (___) ^t\12
The base of the exponential function model in order to get 15% decay should be 0.85
In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation.
The first step would be figuring out the function's base.
The function's form should be, [tex]y=a*b^{t}[/tex]
Here,
'a' denotes the starting value.
'b' denotes the decrease rate.
't' denotes time.
According to the question, the exponential function model is,

In order to get a 15% decay,
The base of the function should be (100-15)/100 = 0.85

Step-by-step explanation:
Quadratic equations follow the general structure:

In this equation, "a" and "b" serve as coefficients which modify the variables and "c" represents the y-intercept. Since the given equation is in the quadratic form, you can easily identify which values match the variables.

According to the adjustable-rate mortgage The new monthly payment in year 8 of the loan is $1292.
According o the statement
we have given that the
Remy obtains a 30-year mortgage in the amount of $625,000 And
She secures a 7/1 ARM at an initial interest rate of 3%. Her initial monthly payment is $2,635.03.
And we have to find the new monthly payment when its interest rate increased to the 4.925%.
So, For this purpose we know that the
An adjustable-rate mortgage (ARM) is a loan with an interest rate that changes.
The amount in which she bought mortgage = 625,000
Interest rate = 3%
Initial amount = 2635.03
From this it clear that the
The amount she pays in 7 years = 2635.03*7
The amount she pays in 7 years = 18445.21
The left amount = 625,000 - 18445.21
The left amount = 606554
It means the rate of interest increased on the amount 606554$
So, According to the 4.925% interest the monthly payment will become
amount on interest rate 4.925% = 4.925% *606554/23 years
amount on interest rate 4.925% = $1292.
So, According to the adjustable-rate mortgage The new monthly payment in year 8 of the loan is $1292.
