Answer:
see below
Step-by-step explanation:
a R=k(L/A)
Substitute what we know into the equation
.08 = k (100/.05)
.08 = k 2000
Divide each side by 2000
.08/2000 = k
.00004 = k
R=.00004 (L/A)
b R=.00004 (L/A)
We know L = 4000 and A = .02
R=.00004 (4000/.02)
R = 8
Which of the following graphs represent a function?
Graph A
Graph B
Graph
Graph
a. Graph A and Graph C
b. Graph A
C. Graph D
D. graph b and d
The graphs that represent functions are given as follows:
a. Graph A and Graph C.
When does a graph represents a function?A graph represents a function if it has no vertically aligned points, that is, each value of x is mapped to only one value of y.
For this problem, we have that:
Graph B has one vertically aligned point, hence it is not a function.Graph D has multiple vertically aligned points, hence it is also not a function.Hence the graphs that represent functions are given as follows:
a. Graph A and Graph C.

Answer:
4(1000) +11(100) + 24(10,000) +11(1000) = 256,100
Step-by-step explanation:
Maybe you want to add 4000 +1100 to 24(10,000) +11,000.
1 thousand = 10 hundreds, so 4000 = 40 hundreds
4000 +1100 = (40 +11) hundreds = 51 hundreds
__
1 ten-thousand = 10 thousands, so 24(10,000) = 240 thousands
24(10,000) +11,000 = (240 +11) thousands = 251 thousands
__
So, we want to add 251,000 and 51 hundreds. The latter can be considered to be 5000 +100, so we have ...
251,000 +5100 = 251,000 +5,100 = (251 +5) thousands + 1 hundred
= 256,100
The angled lines used to indicate the surfaces which are cut by the imaginary cutting-plane are called:
Answer:
Section lines
Step-by-step explanation:
Sectioning is the process of cutting a surface by an imaginary plane, the view of the surface that is cut is shown in the section view.
Section lines are used to indicate where an imaginary cutting plane cuts a material. The imaginary cut is then represented using section lines which are usually thin, crosshatched.
Section lines shows the surface that have been cut by the cutting plane. There are different ways of sectioning such as full section, half section, off set section and so on

what is the probability of spinning a multiple of 3 The Spinner is 1-8 numbered
Answer:
1/4
Step-by-step explanation:
There are 8 possible outcomes
Multiples of 3 are
3,6 = 2 outcomes
P ( multiple of 3) = number of multiples of 3/ total
= 2/8
= 1/4
The probability of spinning a multiple of 3 The Spinner is 1-8 numbered will be [tex]P= \dfrac{1}{4}[/tex]
What is probability?Probability is the extent to which an event is likely to occur, measured by the ratio of the favourable cases to the whole number of cases possible.
There are 8 possible outcomes
Multiples of 3 are
3,6 = 2 outcomes
[tex]\rm P ( multiple \ of\ 3) =\dfrac{ number\ of\ \ multiples\ of\ 3 }{ total }[/tex] [tex]= \dfrac{2}{8}[/tex] [tex]= \dfrac{1}{4}[/tex]

Chester, the dog, loves to eat treats. He has eaten twice as many today as yesterday. He has eaten a total of 15 dog treats in both days.
-write the equation-
Answer:
The equations are:
[tex]T = 2Y[/tex] and [tex]T + 2Y = 15[/tex]
Step-by-step explanation:
Given
Represent bones eaten Today with T and yesterday with Y
Required
Write the equation
In the first statement, we have that:
[tex]T = 2Y[/tex]
Reading further; In the second statement
[tex]T + 2Y = 15[/tex]
Hence, the equations are:
[tex]T = 2Y[/tex] and [tex]T + 2Y = 15[/tex]
Solving further:
Substitute 2Y for T in the second equation
[tex]2Y + 2Y = 15[/tex]
[tex]4Y = 15[/tex]
Divide both sides by 4
[tex]Y = \frac{15}{4}[/tex]
[tex]Y = 3.75[/tex]
Recall that

KNM = 131
Step-by-step explanation:
(8x - 5) + (4x - 19) = 180
12x - 24 = 180
12x = 204
x = 17
Answer:
x = 17
Step-by-step explanation:
Opposite Angles must be the Same Value so In other words, 2(8x - 5) + 2(4x - 19) = 360.
2(8x - 5) + 2(4x - 19) = 360
24x - 48 = 360

From the question we are told that
The proportion of people that own a dog is [tex]p = 0.59[/tex]
Generally the probability of the two selected people owning a dog is mathematically evaluated as
[tex]P(O) = p^2[/tex]

Logan wants to have $130,000 to pay for a surgery on his retractable forearm claws in 30 months. If he can invest money in an account right now that will give him 7.5% interest compounded monthly, how much would he have to
invest now to end up with the amount needed for the surgery later on?
Answer: $107,836.69 or about $107,837 (to the nearest dollar)
Step-by-step explanation:
Formula to the accumulated amount received after investing principal amount (P) at rate of interest (r) compounded monthly for t months :
[tex]A=P(1+\dfrac{r}{12})^{t}[/tex]
As per given , A = $130,000
r= 7.5% = 0.075
t= 30 months
Now,
[tex]130000=P(1+\dfrac{0.075}{12})^{30}\\\\\Rightarrow 130000=P(1+0.00625)^{30}\\\\\Rightarrow 130000=P(1.00625)^{30}\\\\\Rightarrow 130000=P \times1.20552661036\\\\\Rightarrow\ P=\dfrac{130000}{1.2055266}=107,836.69[/tex]
Hence he need to invest $107,836.69 .
The water level as a river recedes after a flood is measured at regular intervals, and its height relative to normal, in inches, follows the sequence below. If the sequence continues, what do you expect the 7th measurement to be? 16, 9, 2, –5, ...,
Answer:
7th measurement = -26
Step-by-step explanation:
The sequence is 16, 9, 2, –5, ...,
First term( a)= 16
Second term=9
Common difference (d) = 9-16
Common difference= -7
The sequence is a arithmetic progression
For AP's ,the terms formula is
Term(n) = a + (n-1)d
Where n represent the term to be found
In this case,we Are looking for the 7th term , so n= 7
Term(7) = 16+ (7-1)-7
Term(7)= 16 +6(-7).
Term (7) = 16-42
Term(7) = -26
7th term =-26

The first significant digit in any number must be 1, 2, 3, 4,5, 6, 7, 8, or 9. It was discovered that first digits do not occur with equal frequency. Probabilities of occurrence to the first digit in a number are shown in the accompanying table. The probability distribution is now known as Benford's Law. Forexample, the following distribution represents the first digits in 187 allegedly fraudulent checks written to a bogus company by an employee attempting to embezzle funds from his employer.

b.) What is the alternative hypothesis?
c.) What is the test statistic?
d.) What is the p-value?
e.) Using the P-value approach, compare the P-value with the given alpha = 0.10, level of significance. Based on theresults, do the first digits obey the Benford's Law?
f.) (b) Based on the results of part (a),could one think that the employee is guilty of embezzlement?

A formula to find the frequency, f, of a cyclic phenomena based on the period, T, is
f = . Solve the formula for T' in terms of f.
Step-by-step explanation:
The frequency and the time period is related by the formula as follows :
[tex]f=\dfrac{1}{T}[/tex]
Here, f is frequency and T is time period
Now, we need to solve T in terms of f.
Firstly, cross multiplying the above equation,
[tex]f\times T=1[/tex]
Now dividing both sides by T.
[tex]\dfrac{f\times T}{T}=\dfrac{1}{T}\\\\f=\dfrac{1}{T}[/tex]
Hence, this is the required solution.
Answer:
T= 1/f
Step-by-step explanation:
T= one OVER f

Answer:
two equal, real solutions
Step-by-step explanation:
The quickest way to determine this is to find the discriminant b^2 - 4ac. If this determinant (D) is > 0, the quadratic has two different real roots; if + 0, the quadratic has two equal real roots, and if < 0, the quadratic has two imaginary or complex roots.
Here a = 5, b = 30 and c = 45. The discriminant is
30^2 - 4(5)(45) = 900 - 900 = 0
and so this quadratic has two equal, real solutions.
