Help w algebra problem!!!

Mathematics
1 answer:
Fantom [35]3 years ago
6 0

Answer:

Step-by-step explanation:

If the circumference of the circle is  x cm the perimeter of the square will be 38-x cm.

The area of the square = (38-x)^2.

The radius  r of the circle = circumference /2π =  x / 2π.

The area of the circle = πr^2 = π * (x / 2π)^2

=  x^2/ 4π.

So total area A = (38 - x)^2 + x^2/4π

A = 1444 - 76x + x^2 + x^2/ 4π

A = x^2 - 76x + 0.07958x^2 + 1444

A =  1.07958x^2 - 76x + 1444

Find the length of the curve y=3x^3/2 from x=0 to x=5/9
Alekssandra [29.7K]
y=3x^{3/2}\implies y'=\dfrac92x^{1/2}

The length of the curve is

L=\displaystyle\int_0^{5/9}\sqrt{1+\left(\dfrac92x^{1/2}\right)^2}\,\mathrm dx=\int_0^{5/9}\sqrt{1+\dfrac{81}4x}\,\mathrm dx=\dfrac{335}{243}

HELP ASAP will give BRAINLIEST
tester [92]

Hey there! I'm happy to help!

The question tells us that m∠JKL is 54. We see from the diagram that this is the combination of the angles m∠JKM and m∠MKL. So, we can combine their values, which are equal to 54 to find x.

13x+1+5x+4=54

We combine like terms

18x+5=54

We subtract 5 from both sides.

18x=49

We divide both sides by 18.

x=2.7222222....

Now, we want to find the measure of m∠MKL. We plug our x value into the value of this angle and evaluate.

5(2.722....)+4=17.61111....... or 17 11/18.

Have a wonderful day and keep on learning! :D

Graph △ABC with vertices A(2, 3), B(−4, −3), and C(2, −3). Find the coordinates of the circumcenter.
Stolb23 [73]
Circumcenter = (-1,0)  
The circumcenter of a triangle is the intersection of the perpendicular bisectors of the sides of the triangle. So let's calculate a couple of the bisectors and determine their intersection. 
 Slope AB = (3 - -3)/(2 - -4) = (3+3)/(2+4) = 6/6 = 1
 Perpendicular bisector will have a slope of -1 and will pass through point ((2-4)/2,(3-3)/2) = -2/2,0/2) = (-1,0)
 Equation is of the form
 y = -x + b
 Substitute known point
 0 = -(-1) + b
 0 = 1 + b
 -1 = b
 So the equation for the perpendicular bisector of AB is
 y = -x - 1 
 Now let's calculate the perpendicular bisector of BC
 Slope BC = (-3 - -3)/(-4 - 2) = (-3 + 3) / (-6) = 0/-6 = 0. This means that the
line is horizontal and that the perpendicular bisector will be a vertical line with infinite slope. A point that line will pass through is ((-4 + 2)/2, (-3 + -3)/2) =
(-2/2, 0/2) = (-1,0). So the equation for the line is:
 x = -1 
 Now we want the intersection between
 x = -1 and y = -x - 1
 Since we know that x has to be -1, just substitute it into the 2nd equation.
 y = -x - 1
 y = -(-1) - 1
 y = 1 - 1
 y = 0
 
 So the circumcenter is (-1,0).
 Let's verify that. The distance from the circumcenter to each vertex of the triangle will be the same. Using the Pythagorean theorem, C^2 = A^2 + B^2. We're not going to bother taking the square root since if the squares are equal, then square roots will also be equal.
 Distance^2 from (2,3):
 (2- -1)^2 + (3-0)^2 = 3^2 + 3^2 = 9 + 9 = 18 
 Distance^2 from (-4,-3):
 (-4 - -1)^2 + (-3 - 0)^2 = -3^2 + -3^2 = 9 + 9 = 18 
 Distance^2 from (2,-3):
 (2 - -1)^2 + (-3 - 0)^2 = 3^2 + -3^2 = 9 + 9 = 18 
 The distances to all three vertexes is identical, so (-1,0) is verified as the circumcenter.

Right answer will get brainlist
exis [7]

Answer:

x = -3

Step-by-step explanation:

System of equations has been given as,

y = 2x + 8

y = -\frac{2}{3}x

Since, solution of the system of equations is the point of intersection on the graph.

Therefore, point of intersection or solution of the system will be,

(x, y) = (-3, 2)

This common point will satisfy both the equations.

And x = -3 will also both the equations.
