The opening in a rectangular door frame measures 9 feet by 3 feet. Each of the four doors described in the table measures 9
feet by 3 feet, but have different diagonal lengths. Which door will fit in the rectangular opening?
Door 1
Door 2
diagonal: 10 feet
Door 3
diagonal 3 V10 feet
Door 4
diagonal: 6
feet
diagonal: 12 feet
Door 1
Door 2
Door 3
Door
Answer:
Door 3 diagonal 3√10 feet
Step-by-step explanation:
The diagonal of a rectangle is the hypotenuse of a right triangle whose legs are the side lengths of the rectangle. That is, the diagonal of a 9 ft by 3 ft rectangle will have length ...
d = √(9² +3²) = √90 = 3√10
Any "9 ft by 3 ft" figure that has a diagonal different from this is not a rectangle. To fit the rectangular opening, we want a rectangular door—one with a diagonal of 3√10 feet.

Door 2

Answer:
X = -1/3, 1/3
Step-by-step explanation:
6x^2 - x = 1
(subtract 1 from both sides)
6x^2 - x - 1 = 0
(factor)
(6x - 3) (6x + 2)
(simplify)
(2x - 1) (3x + 1)
(Solve for x in each parentheses)
2x-1= 0 and 3x+1=0
X= -1/2 X= -1/3
Answer:
x=-1/2,-1/3
Step-by-step explanation:
6x²-x = 1 <- Rewrite
-1 -1 <- Subtract 1 from both sides
6x²-x-1 = 0
x²-x-6 = 0 <- Slide the x²'s coefficient over to the variable with no coefficient through multiplication
(x-3)(x+2)=0 <- Factor
(x-3/6)(x+2/6)=0 <- Divide the 6 back out and simplify
(x-1/2)(x+1/3)=0 <- Simplify
(2x-1)(3x+1)=0 <Bring the denominator in front of the x
2x+1 = 0 and 3x+1 = 0 <- Seperate the two and solve
-1 -1 -1 -1
2x = -1 and 3x = -1
x = -1/2 and x = -1/3
so
x=-1/2,-1/3

1. Rocco purchases a car for $14,950. There is a sales tax of 6.5%.
How much is the final price with tax?
Use the formula amount = cost x tax rate to find the amount of the
sales tax.
Add the cost of the car to the amount of the sales tax to find the final
price.
Answer:
The final price with tax is 15,921.75, and the total tax added was 971.75
Step-by-step explanation:
To find the final cost, you multiply the cost of the product by the tax rate plus one.
For this problem, you multiply 14,950 by (0.065 + 1) to get the answer
Answer:
$15,921.75
Step-by-step explanation:
1. Multiply the cost of the car by the sales tax rate.
14950*.65= 971.75
2. Then add this amout to the original cost of the car.
14950 + 971.75= $15,921.15

A bag contains 2 snickers bars, 8 twix bars, and 5 crunch bars. A candy bar is chosen, the replaced, then another is chosen. What is the probability of choosing a twix bar and then a crunch bar? (Please answer with a fraction and not a percentage)
2 + 8 + 5 = 15 total candy bars.
8 twix, so picking a twix would be 8/15
5 crunch bars, picking a crunch would be 5/15, which reduces to 1/3
Probability of both: 8/15 x 1/3 = 8/45

Determine the intercepts of the line
Pls mark Brainliest.
Answer:
Y-intercept or b = 2.5
X-intercept = 3.5
Step-by-step explanation:
The y-intercept is where the graph intersects on the y-axis, where x=0.
Thus, the y-intercept or b = 2.5.
The x-intercept is where the graph intersects on the x-axis, where y=0.
Thus, the x-intercept = 3.5.

A 1/2 Kilogram of flour is packed equally into 8 bags. How much flour is in each bag?
Answer:
1/16
Step-by-step explanation:
So if you want to divide an amount equally, you divide the numbers. In this scenario, what you would do is this:
1/2 needs to be split 8 times
(1/2)/8
If you have something like this where the numerator is a fraction, then you multiply 2x8. that gives you 16, so now you add the 1 on top and you get 1/16.
To estimate the mean score μ of those who took the Medical College Admission Test on your campus, you will obtain the scores of an SRS of students. From published information you know that the scores are approximately Normal with standard deviation about 6.3 . You want your sample mean ¯ x to estimate μ with an error of no more than 1.3 point in either direction.
(a) What standard deviation must ¯ x have so that 99.7 % of all samples give an ¯ x within 1.3 point of μ ? Use the 68 – 95 – 99.7 rule. (Enter your answer rounded to four decimal places.)
(b) How large an SRS do you need in order to reduce the standard deviation of
¯
x
to the value you found? (Enter your answer rounded to the nearest whole number.)
Answer:
a. 0.4333
b. 255
Step-by-step explanation:
The maximum Error E is 1.3
approximately normal test scores,
Standard Deviation, SD is 6.5
a).
Level of confidence = 99.7%
critical value of z for a two tailed test and 0.3% level of significance is 3
since the sample mean is within 0.5 of the true population mean
hence, the standard dev of mean is given by
[tex]Z_{\alpha}[\frac{\sigma}{\sqrt{n}} ]=E[/tex]
where E = 1.3
[tex]Z_{\alpha}=[/tex] 1.3
[tex]\frac{\sigma}{\sqrt{n}} =\frac{E}{Z_{\alpha}} \\\\\frac{\sigma}{\sqrt{n}} =\frac{1.3}{3}[/tex]
hence the Std of the mean is 0.4333 (to 4 d.p.)
b).
The sample size is computed as follows
making n the subject of formular of the above equation
[tex]\sqrt{n} =\frac{3\sigma}{1.3}} \\\\\sqrt{n} =\frac{3\times 6.5}{1.3}} \\\\n=(\frac{3\times 6.5}{1.3}})^2[/tex]
hence,
n = 255
What are the wavelengths for X-rays with frequency 3 × 1018? 1 × 10–10 m 3 × 10–10 m 3 × 1026 m 9 × 1026 m
Answer:
[tex]Wavelength=\lambda=1\times 10^{-10}[/tex] mStep-by-step explanation:
Given that the wavelengths for X-rays with frequency [tex]3\times 10^{18}[/tex]
To find the wavelengths for the given X-rays:The distance between two peaks in a wave is called the wavelength.
The value of wavelength is equal to the wave velocity divided by the frequency.
That is written by
[tex]Wavelength=\lambda =\frac{v}{f}[/tex]
[tex]Wavelength =\frac{3\times 10^8}{3\times 10^{18}}[/tex]
[tex]=\frac{10^8}{10^{18}}[/tex]
[tex]=\frac{1}{10^{18}.10^{-8}}[/tex] (by using the property [tex]a^m=\frac{1}{a^{-m}}[/tex])
[tex]=\frac{1}{10^{18-8}}[/tex] (by using the property [tex]a^m.a^n=a^{m+n}[/tex])
[tex]=\frac{1}{10^{10}}[/tex]
[tex]=1\times 10^{-10}[/tex] m (by using the property [tex]\frac{1}{a^{m}}=a^{-m}[/tex])

Write the equation of the circle.
A circle with a diameter having endpoints at (0, 1) and (6,-4)
Answer:
(x - 3)² + (y + 1.5)² = 15.25
Step-by-step explanation:
Centre: midpoint of the diameter
(h,k) = (0+6)/2, (1-4)/2
= (3, -3/2)
Radius = ½(diameter)
Diameter = sqrt(6² + (-4-1)²)
sqrt(61)
Radius = sqrt(61)/2
Equation:
(x - h)² + (y - k)² = r²
(x - 3)² + (y + 1.5)² = 15.25

The cost of producing x bags of dog food is given by C(x) = 800 + 400 + 10x - x where 0 SX 55000. Find the marginal-cost function.
The marginal-cost function is c'(x)=
(Use integers or fractions for any numbers in the expression.)
Answer:
The marginal-cost function is;
c'(x)= (20x-1)/(2√(400 + 10x² - x))
Completed question;
The cost of producing x bags of dog food is given by C(x) = 800 + √(400 + 10x² - x) where 0≤x≤55000. Find the marginal-cost function.
The marginal-cost function is c'(x)=
(Use integers or fractions for any numbers in the expression.)
Step-by-step explanation:
The marginal-cost function is c'(x)= = dC(x)/dx
Where;
C(x) = 800 + √(400 + 10x² - x)
c'(x) = d(800 + √(400 + 10x² - x) )/dx
Using function of function rule of differentiation or chain rule;
c'(x) = (20x-1)×(1/2√(400 + 10x² - x))
c'(x) = (20x-1)/(2√(400 + 10x² - x))
The marginal-cost function is;
c'(x)= (20x-1)/(2√(400 + 10x² - x))
Final answer:
The marginal-cost function c'(x) is 9.
Explanation:
Marginal-cost function:
Given cost function: C(x) = 800 + 400 + 10x - x
Find derivative of C(x): C'(x) = 10 - 1 = 9
Therefore, the marginal-cost function is c'(x) = 9
