The length of one leg of the right triangle is 5√10
How to find the leg of a right triangle?The leg of a right triangle can be found as follows;
Therefore, using trigonometric ratios,
sin 45 = opposite / hypotenuse
sin 45 = x / 10√5
1 / √2 = x / 10√5
cross multiply
10√5 = x√2
divide both sides by √2
x = 10√5 / √2
x = 10√5 / √2 × √2 / √2
x = 10√10 / 2 = 5√10

Option b. The oversight was discovered during the preparation of gators' 2021 financial statements. depreciation expense on this machine for 2021 should be $372,000.
The yearly straight-line devaluation cost for the machine would be $186,000 ($930,000/5). In any case, since no deterioration was perceived in 2020, the collected devaluation toward the start of 2021 would be $0 rather than $186,000. In this manner, the complete devaluation cost for 2021 would be the yearly deterioration of $186,000 in addition to the get up to speed devaluation for 2020 of $186,000, for a sum of $372,000.

Many electronic devices use disposable batteries, which eventually have to be replaced. Assume that for one particular brand and type of battery, the distribution of the hours of useful power can be approximated well by a Normal model. The mean is 140 hours, and the stand deviation is 4 hours. The marketing department wants to write a guarantee for battery life. What lifespan should they quote so that they can expect 98% of the batteries to meet the guarantee
Answers
They should quote 150 hours so that they can get 98% of the batteries to meet the guarantee.
Given mean of 140 hours and standard deviation of 4 hours with confidence level=98%.
We have to find the lifespan which they should quote to get 98% confident that their batteries meet the guarantee.
We have to use z test for this .
μ=140 hours and σ=4 hours
Z=X-μ/σ
When p value is 0.98 then from z table z value will be 2.58.
Z=X-140/4
2.58=X-140/4
2.58*4=X-140
10.32=X-140
X=150.32
after rounding off we will get 150 hours.

(sin(x) + cos(x))² / sin(2x)= csc (2x) + 1
Answers
See below for the proof of the trigonometry identity
The approach to takeThe identity is given as:
(sin(x) + cos(x))² / sin(2x)= csc (2x) + 1
Start by expanding the numerator
(sin²(x) + cos²(x) + sin(2x)) / sin(2x)= csc (2x) + 1
Express sin²(x) + cos²(x) as 1
(1 + sin(2x)) / sin(2x)= csc (2x) + 1
Expand the fraction
1/sin(2x) + sin(2x)/sin(2x) = csc(2x) + 1
Evaluate the quotient
csc(2x) + 1 = csc(2x) + 1

A line passes through the points (-6, 4) and (-2, 2). Which is the equation of the line?
y=-x+1
y=1/√x+7
y=-2x-8
y = 2x + 16
Answers
Answer:
Correct answer not shown on the options.
y = -(1/2)+1
Step-by-step explanation:
Let's find an equation in the format of y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).
The slope can be calculated as the Rise/Run of the line between the two given points (-6,4) and (-2,2):
Rise = (2 - 4) = -2
Run = (-2 - (-6)) = 4
Slope = Rise/Run = -2/4 or -(1/2)
In fact, the actual full equation is y= -(1/2)x+1 (See attached graph).
None of the options have a slope of -(1/2). Either the information on the two points or the options are incorrect.
Answer:
y=[tex]-\frac{1}{2}x[/tex]+1
Step-by-step explanation:
y = mx plus c,where m is the gradient.
∴m =[tex]\frac{y2-y1}{x2-x1}[/tex]=[tex]\frac{2-4}{-2-(-6)}[/tex]=[tex]\frac{-2}{4}[/tex]=[tex]-\frac{1}{2}[/tex]
Equation of a line equals
y-y1=m(x-x1) (Using point (-6, 4) for x1 and y1 values)
y-4=[tex]-\frac{1}{2}[/tex](x-(-6))
y-4=[tex]-\frac{1}{2}[/tex](x+6)
y-4=[tex]-\frac{1}{2}[/tex]x-3
2(y-4)=-x-3(2)(multiply through by 2)
2y-8=-x-6
2y=-x+2(divide through by 2)
y=[tex]-\frac{1}{2}x[/tex]+1
∴the equation of the line is y=[tex]-\frac{1}{2}x[/tex]+1

The proper sequence of steps in implementing the model in Excel presented in the textbook is option b which is organize the data, represent the decision variables, represent the objective function, represent the constraints and represent the bounds on the decision variables.
Given process of implementing the model in Excel and we have to choose the correct process.
The process of implementing the model in Excel is as under:
1) Organize the data: In excel, to organize the data we have to put similar items in the same column. We have to design the data so that all rows have similar items in the same column. We have to keep a range of data separate and leave at least one blank column and one blank row between a related data range.
2) Represent the decision variables: Now we have to represent the decision variables according to which logical function performs tasks.
3)Represent the objective function: It is important because on the basis of this all the logical function perform tasks.
4) Represent the constraints: In excel when we are using solver we have to now represent the constraints of the objective function.
5) Represents the bounds on the decision variables.
Hence the proper sequence of steps in implementing the model in excel is Organize the data, represent the decision variables, represent the objective function, represent the constraints, and represent the bounds on the decision variables.

B) 6x² + 20x + 2x² + 10x + 18
C) 2(4x² + 15x + 9)
D) 4(2x² + 7x + 4)
Answers
Answer:
A, C, and D
Step-by-step explanation:
A) (4x + 3) (2x + 6) is equal to 8x² + 30x + 18 because when you multiply two binomials, you use the distributive property. The distributive property states that for any numbers a, b, and c, a(b + c) = ab + ac. So, (4x + 3) (2x + 6) can be rewritten as (4x)(2x) + (4x)(6) + (3)(2x) + (3)(6). This can further be simplified to 8x² + 24x + 18.
C) 2(4x² + 15x + 9) is equal to 8x² + 30x + 18 because when you multiply a number by a binomial, you use the distributive property. The distributive property states that for any numbers a, b, and c, a(b + c) = ab + ac. So, 2(4x² + 15x + 9) can be rewritten as 2(4x²) + 2(15x) + 2(9). This can further be simplified to 8x² + 30x + 18.
D) 4(2x² + 7x + 4) is equal to 8x² + 30x + 18 because when you multiply a number by a binomial, you use the distributive property. The distributive property states that for any numbers a, b, and c, a(b + c) = ab + ac. So, 4(2x² + 7x + 4) can be rewritten as 4(2x²) + 4(7x) + 4(4). This can further be simplified to 8x² + 28x + 16.

Therefore, both points are the same distance away from 0 just in opposite directions.
That means point Q is always going to equal the negative of point P. An example of this is if point p equals 5, point p equals -5.

It is given that the rocket that will return the rock and soil samples to Earth cannot lift off if the total weight of the samples from the rovers exceeds 530 pounds.
In probability theory and statistics, the binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a sequence of n independent experiments, each asking a yes–no question, and each with its own Boolean-valued outcome: success (with probability p) or failure (with probability q = 1 − p). A single success/failure experiment is also called a Bernoulli trial or Bernoulli experiment, and a sequence of outcomes is called a Bernoulli process; for a single trial, i.e., n = 1, the binomial distribution is a Bernoulli distribution.
