el perimetro de un terreno rectangular es de 170m y su area es de 170^2hallar la medida de sus lados con ecuacion cuadratica
Answer:
Acá tenemos un sistema de ecuaciones.
El perímetro de un rectángulo es:
2*A + 2*L = 170m
donde A es el ancho y L es el largo.
Y el área del rectángulo es:
A*L = 170m^2.
Entonces, el primer paso es aislar una de las variables en una de las ecuaciones, yo voy a aislar A en la segunda:
A = 170m^2/L.
Ahora reemplazo eso en la primera ecuación y la resuelvo para L.
2*( 170m^2/L.) + 2*L = 170m.
340m^2 + 2*L^2 = 170m*L
ahora tenemos una ecuación cuadrática:
2*L^2 - 170m*L + 340m^2 = 0.
Las soluciones se pueden obtener usando la formula de Bhaskara:
[tex]L = \frac{+170 +- \sqrt{170^2 -4*340*2} }{2*2} = \frac{170 +-161.8}{4}[/tex]
Entonces las soluciones son:
L = (170 + 161.8)/4 = 82.95m
L = (170 - 161.8)/4 = 4.1m
Entonces, si tomamos L = 82.95m, tenemos A = 4.1 m
y el área es:
A*L = 4.1m*82.95m = 170m^2
Select the interval where h(x)>0 {where h of x is greater than 0}
Option1. -3.5 Option2. -2 Option3. 2.5
Answer:
The correct option is;
Option 3. 2.5
Step-by-step explanation:
From the graph of the function y = h(x), where h of x h(x) > 0 and x > 0 we have;
The first interval where y =h(x) > 0 occurs between x= 0 and x = 0.8
The second interval where y =h(x) > 0 occurs between 2.2 and 4 which is a range of 4 - 2.3 = 1.7
The total interval where y =h(x) > 0 occurs is therefore = 0.8 + 1.7 = 2.5
Thus the function y = h(x), is positive over an interval on the x-axis = 2.5.

At the beginning of year 1, Josie invests $400 at an annual compound interest rate of 5%. She makes no deposits to or withdrawals from the account. Which explicit formula can be used to find the account's balance at the beginning of year 3?
A. A(3) = 400 • (1 + 0.05)3 – 1
B. A(3) = 400 + (3 – 1)(0.05 • 400)
C. A(3) = 400 + (0.05 • 400)3 – 1
D. A(3) = 400 • (1 + 0.05)3
Answer: A
Step-by-step explanation:
Since she invested $400 in the beginning if the 1st year and we are asked to find the balance at the beginning of the third year, she earns interest only for the first two years. So, the formula will be
Amount = 400 (1 + 0.05) ^3-1
To find the balance in Josie's account at the beginning of the the third year we have to use A(3)=[tex]400*(1+0.05)^{3-1}[/tex]
What is Compound interest?It is the interest calculated on the initial principal amount and the accumulated interest. The formula to calculate the sum after compound interest is
Sum= [tex]P(1+r/m)^{tm}[/tex] where P=principal, r= rate of interest, m= number of times compounded in a year, t=time
How to calculate sum when interest is compounding?At the beginning of year 1, Josie invests $400 at an annual compound interest at the rate of 5%,then the amount at the beginning of year 3 is calculated as:
The amount in beginning of 1 year=$400
The amount at the end of the year 1=400+400*0.05=400(1+0.05)
The amount at the end of year 2=400(1+0.05)+400(1+0.05)*0.05
=[tex]400(1+0.05)^{2}[/tex]
=[tex]400(1+0.05)^{3-1}[/tex]
Hence the option A is correct which is to be used to calculate the amount in Josie's account at the beginning of year 3.

The center of the circle lies on the y-axis. The standard form of the equation is (x – 1)² + y² = 3. The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.
The standard equation of a circle is expressed as:
[tex]x^2+y^2+2gx+2fy+C=0[/tex]
Centre is (-g, -f)radius = √g²+f²-CGiven a circle whose equation is [tex]x^2 + y^2 - 2x - 8 = 0.[/tex]
Get the centre of the circle
2gx = -2x
2g = -2
g = -1
Similarly, 2fy = 0
f = 0
Centre = (-(-1), 0) = (1, 0)
This shows that the center of the circle lies on the x-axis
r = radius = √g²+f²-C
radius = √1²+0²-(-8)

(a) Compute the z-score corresponding to the individual who obtained 32.3 miles per gallon. Interpret this result. (b) Determine the quartiles. (c) Compute and interpret the interquartile range, IQR. (d) Determine the lower and upper fences. Are there any outliers?
Answer:
Explained below.
Step-by-step explanation:
The data provided is as follows:
S = {31.5, 36.0, 37.8, 38.5, 40.1, 42.2, 34.2, 36.2, 38.1, 38.7, 40.6, 42.5, 34.7. 37.3, 38.2, 39.5, 41.4, 43.4, 35.6, 37.6, 38.4, 39.6, 41.7, 49.3}
Compute the mean and standard deviation as follows:
[tex]\mu=\frac{1}{n}\sum X=\frac{1}{24}\times [31.5+36.0+37.8+...+49.3]=38.88\\\\\sigma=\sqrt{\frac{1}{n-1}\sum (X-\mu)^{2}}=\sqrt{\frac{1}{24-1}\times 299.639584}=3.61[/tex]
(a)
Compute the z-score corresponding to the individual who obtained 32.3 miles per gallon as follows:
[tex]z=\frac{X-\mu}{\sigma}[/tex]
[tex]=\frac{32.3-38.88}{3.61}\\\\=-1.823[/tex]
Thus, the z-score corresponding to the individual who obtained 32.3 miles per gallon is -1.823.
(b)
The data set arranged in ascending order is:
S = {31.5 , 34.2 , 34.7 , 35.6 , 36 .0, 36.2 , 37.3 , 37.6 , 37.8 , 38.1 , 38.2 , 38.4 , 38.5 , 38.7 , 39.5 , 39.6 , 40.1 , 40.6 , 41.4 , 41.7 , 42.2 , 42.5 , 43.4 , 49.3}
The set consists of 24 values.
The first and third quartile are:
[tex]Q_{1}=[\frac{n+1}{4}]^{th}\ obs.=[\frac{24+1}{4}]^{th}\ obs.=12.5^{th}\ obs.=\frac{36.2+ 37.3}{2}=36.75\\\\Q_{3}=[\frac{3(n+1)}{4}]^{th}\ obs.=[\frac{3(24+1)}{4}]^{th}\ obs.=18.75^{th}\ obs.=\frac{40.6+41.4}{2}=41[/tex]
Thus, the value of Q₁ is 36.75 and Q₃ = 41.
(c)
Compute the inter-quartile range as follows:
[tex]IQR=Q_{3}-Q_{1}=41-36.75=4.25[/tex]
The inter-quartile range is 4.25.
The inter-quartile range is the amount of data that is contained within the middle 50% of a set of observations, when arranged in order. It is the distance between the first and third quartile.
(d)
Compute the values of lower and upper fences as follows:
[tex]\text{Lower fence}=Q_{1}-1.5\times IQR=36.75-(1.5\times 4.25)=30.375\approx 30.38\\\\\text{Upper fence}=Q_{3}+1.5\times IQR=41+(1.5\times 4.25)=47.375\approx 47.38[/tex]
Any values that are less than the lower fence or more than the upper fence are considered as outlier.
Consider the arranged data set.
Only one value is more than the upper fence, 47.38, i.e. 49.3.
So, yes there is one outlier, i.e. 49.3.
Translate into an algebraic expressions: 120 is increased by d% and increased by 25% . What is the result ?
Answer:
The result is 150 + 1.5d
Step-by-step explanation:
We want to translate the wordings into algebraic expression.
Firstly, we increase 120 by d%
d% = d/100
So increasing 120 by d % means;
120 + (d/100 * 120)
= 120 + 1.2d
Then increase this by 25%
= (120 + 1.2d) + 25/100(120 + 1.2d)
= 120 + 1.2d + (120+1.2d)/4
= 120 + 1.2d + 30 + 0.3d
= 120 + 30 + 1.2d + 0.3d
= 150 + 1.5d

Step-by-step explanation:
Answer:
y = 5/12 x + 2
Step-by-step explanation:
We need to find the equation of a line that passes through two given points.
y = mx + b
First, we find the slope.
m = slope = (y2 - y1)/(x2 - x1)
m = (7 - 2)/(12 - 0) = 5/12
Now we have
y = 5/12 x + b
To find the value of b, we use a point for x and y and solve for b.
y = (5/12)x + b
2 = (5/12)(0) + b
b = 2
The equation is
y = 5/12 x + 2
C=5/9(F - 32) concert 30C to Fahrenheit
Answer:
132
Step-by-step explanation:
132
Hey there! :)
Answer:
86° F.
Step-by-step explanation:
Use the formula C = 5/9(F - 32) to convert 30C to Fahrenheit. Plug 30 into C:
30 = 5/9(F - 32)
Multiply both sides by 9/5 (dividing by 5/9):
30 · 9/5 = 5/9(F - 32) · 9/5
54 = F - 32
Add 32 to both sides:
54 + 32 = F - 32 + 32
F = 86°.
Therefore, 30C = 86° F.

Hey there!
First; let us understand that there are 360° in a full circle.
This is what we are representing.
We need to find a way to multiply to get the answer.
36% of 360 = 0.36, therefore we need to make 0.36 x 360
Multiply 0.36 x 360
Therefore, we get 129.6°
EXACT Answer:129.6°
Rounded answer:130°
Answer: 129.6
Step-by-step explanation:
So, there are 360 in one full circle.
We will multiply to get a product.
36% of 360 = 0.36, Make 0.36 x 360
0.36 x 360 = 129.6

Based on the line of best fit, what is the approximate maximum depth of a lake that has 31 miles of shoreline? A. 121 feet B. 132 feet C. 138 feet D. 143 feet
Answer: D. 143
Step-by-step explanation:
31 times 4.26 = 132.06 + 10.908 = 142.968 which simplifies to 143 because you round up.
The best line of fit for the maximum depth of the shoreline would be: D. 143 feet
How to solve for the depth of the shorelineWe have the line of fit as
y = 4.26x + 10.908.
The question has specified x as 31 miles which is the miles of shore line.
We have to solve for the value in the line of best fit
y = 4.26*31 + 10.908
y = 132.06 + 10.908
y = 142.968
This is approximately D. 143 feet
