Par on a golf course is 72. If a golfer shot rounds of 74, 67, and 73 in a tournament, what will she need to shoot on the final round to average par?
Answer:
74
Step-by-step explanation:
By average definition:
(74 + 67 +73 +x) / 4 = 72
Multiply by 4
(74 + 67 +73 +x) = 288
shift the first three terms on the right side
x = 288 -74 -67 -73 = 74
solve the system by elimination 4x-y=2 and x+3y=7
Answer:
x=1 y=2
Step-by-step explanation:
Isolate x for 4x -y =2: x=2+y/4
Substitute x= 2+y/4
(2+13y/4) +3y=7
simplify 2+13y/4) =7
Isolate y for 2+13y/4) =7: y=2
Forx= 2+y/4
Substitute y =2
x=2+2/4
x=1

when solving a quadratic equation by factoring you must set y equal to what value? y=x2 + 3x - 4
Answer:
x^2 +3x -4 = 0 --> (x +4)(x -1) = 0
Step-by-step explanation:
Let's find A and B such that
A*B = - 4 and A+B = 3
Numbers are:
A = +4 and B = -1
The factoring equation is y = (x + A)(x + B)
In this specific case: y = (x +4)(x -1)
Solutions to the quadratic equation require
y = (x +4)(x -1) = 0
and hence
x +4 = 0 --> x = -4
x - 1 = 0 --> x= +1

The formula for the volume of a right circular cylinder is
V = πr² h. If r = 2b and h = 5b +3 then what is the
volume of the cylinder in terms of b?
A 10b2 + 67b
B 20πb³ + 12πb²
C 20π²6³ +12π²b²
D 50пь3 + 20пb2 + 90nb
Answer:
B. 20πb³ + 12πb²
Step-by-step explanation:
The equation for the volume is incorrect, the volume of a cylinder with radius (r), and height (h), is πr²h.
The volume of the cylinder in terms of[tex]20\pi b^3 + 12\pi b^2[/tex]. Option B is correct.
A cylinder is a three-dimensional figure with two bases that are joined with a curved surface.
The total space occupied by the three-dimensional figure is called volume.
Given that:
The Volume is V = [tex]\pi r^2 h[/tex]
Radius r = 2b
Height,h = 5b +3
Substitute the values into the formula for the volume of a cylinder
V = πr²h
V =[tex]\pi \times (2b)^2 \times (5b + 3)[/tex]
Simplify the expression:
V = [tex]4\pi b^2 \times (5b + 3)[/tex]
Use the distributive property to get the values.
V = [tex]20\pi b^3+ 12\pi b^3[/tex]
So, the volume of the cylinder in terms of[tex]20\pi b^3 + 12\pi b^2[/tex]. Option B is correct.

Answer:
-56
Step-by-step explanation:
First lets solve the bottom of the fraction :
1/7 * -1/8 is equal to -1/56 because to multiply two fractions we multiply there numerators and denominators
Now we have to divide 1 by -1/56 which is equal to :
1 *-56= -56 becasue when dividing by a fraction you want to switch its numerator and denominator
At the end you get -56
A rectangular picture has a length of 40 inches and a width of 9 inches.
What is the length of the diagonal of the picture in inches?
Enter your answer in the box.
inches
Step-by-step explanation:
the length and the width of a rectangle create a right-angled triangle, with the diagonal being the Hypotenuse of that triangle (the baseline, opposite of the 90° angle).
so, we can use Pythagoras
c² = a² + b²
with c being the Hypotenuse.
so, we have here
diagonal² = 40² + 9² = 1600 + 81 = 1681
diagonal = sqrt(1681) = 41 in
Simplify the expression.

What is the value of x?
Answer:
[tex]x = 52[/tex]
Step-by-step explanation:
Step 1: Create an expression
[tex]2x + 76 = 180[/tex]
Step 2: Subtract 76 from both sides
[tex]2x + 76 - 76 = 180 - 76[/tex]
[tex]2x = 104[/tex]
Step 3: Divide both sides by 2
[tex]\frac{2x}{2} = \frac{104}{2}[/tex]
[tex]x = 52[/tex]
Answer: [tex]x = 52[/tex]
Answer:
x = 52
Step-by-step explanation:
the 2 inside angles add up to 180 degress since they lie on the same side on the transversal line. so we set the eqaution up:
2x+76=180
2x=104
x=54
help i need big brain answers!!!! At what position on the number line is the red dot located?
Answer:
it is 57
Step-by-step explanation:
Answer:
A. √57
Step-by-step explanation:
√47 would be off the number line because it's below the number 7
√65 would be past 8 but the red dot comes before the number 8
√72 would be past 8 as well and it would be past √65 but the dot is before number 8
This leaves our answer as √57 beause the square root of 57 is 7.549 (etc.) which is between the numbers 7 and 8, while also being slightly higher than 7.5 :)

24) Find center vertices foci asymptotes
The given equation represents a hyperbola. Its main features are:
center - (1,-3)vertices - V1= (1,-3+[tex]\sqrt{2}[/tex]) / V2= (1,-3-[tex]\sqrt{2}[/tex])foci - F1= (1 , -3+ [tex]2\sqrt{5}[/tex] )/ F2= (1 , -3 - [tex]2\sqrt{5}[/tex] )asymptotes = [tex]\pm \frac{1}{3}\left(x-1\right)-3[/tex]HyperbolaA hyperbola can be defined by its center, vertices, foci and asymptotes. And it is represented algebraically by the standard equation: [tex]\frac{\left(y-k\right)^2}{a^2}-\frac{\left(x-h\right)^2}{b^2}=1[/tex], where:
h= x-coordinate of center
k= y-coordinate of center
a and b= semi-axis
First, you need to rewrite the given equation 9y²-x²+2x+54y+62=0 in the standard equation hyperbola:
[tex](-x^2+2x+?)+9(y^2+6y+?)=-62\\(-x^2+2x+?)+9(y^2+6y+9)=-62\\(-x^2+2x-1)+9(y^2+6y+9)=-62\\(-x^2+2x-1)+9(y^2+6y+9)=-62-1+81\\((-x^2+2x-1)+9(y^2+6y+9)=18 ) \div 18\\ \frac{(-x^2+2x-1)}{18} +\frac{9(y^2+6y+9}{18}= \frac{18}{18} \\\frac{-(x-1)^2}{18} +\frac{(y+3^2)}{2}=1\\\frac{-(x-1)^2}{(3\sqrt{2})^2} +\frac{(y+3^2)}{(\sqrt{2})^2 }=1\\\frac{\left(y+3)^2}{\left(\sqrt{2}\right)^2}-\frac{\left(x-1\right)^2}{\left(3\sqrt{2}\right)^2}=1[/tex]
Comparing the previous equation with the standard form ([tex]\frac{\left(y-k\right)^2}{a^2}-\frac{\left(x-h\right)^2}{b^2}=1[/tex]), you have:
h=1, k=-3, a=[tex]\sqrt{2}[/tex] and b=[tex]3\sqrt{2}[/tex] . From now, it is possible to find that the question asks:
Find the centerThe coordinates for center is (h,k). Thus, the center is (1,-3).
Find the verticesThe vertices (V1 and V2) of hyperbola can be found from the coordinates of center (h,k) and the semi-axis (a).
V1= (h,k+a)= (1,-3+[tex]\sqrt{2}[/tex])
V2= (h,k-a)= (1,-3-[tex]\sqrt{2}[/tex])
Find the fociThe foci or the focus points can be found from the coordinates of center (h,k) and the c ([tex]\sqrt{a^2+b^2}[/tex]) which represents the distance from the center to the focus.
[tex]c=\sqrt{a^2+b^2}\\ c=\sqrt{(3\sqrt{2} )^2+(\sqrt{2} )^2}\\c=\sqrt{18+2} \\c=\sqrt{20}=2\sqrt{5}[/tex]
Thus,
F1= (h,k+c)= (1 , -3+ [tex]2\sqrt{5}[/tex] )
F2= (h,k-c)= (1 , -3 - [tex]2\sqrt{5}[/tex] )
Find the asymptotesThe asymptotes are the lines the hyperbola tends to at ±∞. For hyperbola, the asymptotes are defined as: [tex]y=\pm \frac{a}{b}\left(x-h\right)+k[/tex]. Then, for this question:
[tex]y=\pm \frac{\sqrt{2}}{3\sqrt{2}}\left(x-1\right)-3\\y=\pm \frac{1}{3}\left(x-1\right)-3[/tex]

[tex] \displaystyle\rm\int \limits_{0}^{ \frac{\pi}{2} } \sqrt[3]{tanx} \ln(tanx)dx[/tex]
Replace [tex]x\mapsto \tan^{-1}(x)[/tex] :
[tex]\displaystyle \int_0^{\frac\pi2} \sqrt[3]{\tan(x)} \ln(\tan(x)) \, dx = \int_0^\infty \frac{\sqrt[3]{x} \ln(x)}{1+x^2} \, dx[/tex]
Split the integral at x = 1, and consider the latter one over [1, ∞) in which we replace [tex]x\mapsto\frac1x[/tex] :
[tex]\displaystyle \int_1^\infty \frac{\sqrt[3]{x} \ln(x)}{1+x^2} \, dx = \int_0^1 \frac{\ln\left(\frac1x\right)}{\sqrt[3]{x} \left(1+\frac1{x^2}\right)} \frac{dx}{x^2} = - \int_0^1 \frac{\ln(x)}{\sqrt[3]{x} (1+x^2)} \, dx[/tex]
Then the original integral is equivalent to
[tex]\displaystyle \int_0^1 \frac{\ln(x)}{1+x^2} \left(\sqrt[3]{x} - \frac1{\sqrt[3]{x}}\right) \, dx[/tex]
Recall that for |x| < 1,
[tex]\displaystyle \sum_{n=0}^\infty x^n = \frac1{1-x}[/tex]
so that we can expand the integrand, then interchange the sum and integral to get
[tex]\displaystyle \sum_{n=0}^\infty (-1)^n \int_0^1 \left(x^{2n+\frac13} - x^{2n-\frac13}\right) \ln(x) \, dx[/tex]
Integrate by parts, with
[tex]u = \ln(x) \implies du = \dfrac{dx}x[/tex]
[tex]du = \left(x^{2n+\frac13} - x^{2n-\frac13}\right) \, dx \implies u = \dfrac{x^{2n+\frac43}}{2n+\frac43} - \dfrac{x^{2n+\frac23}}{2n+\frac23}[/tex]
[tex]\implies \displaystyle \sum_{n=0}^\infty (-1)^{n+1} \int_0^1 \left(\dfrac{x^{2n+\frac43}}{2n+\frac43} - \dfrac{x^{2n+\frac13}}{2n-\frac13}\right) \, dx \\\\ = \sum_{n=0}^\infty (-1)^{n+1} \left(\frac1{\left(2n+\frac43\right)^2} - \frac1{\left(2n+\frac23\right)^2}\right) \\\\ = \frac94 \sum_{n=0}^\infty (-1)^{n+1} \left(\frac1{(3n+2)^2} - \frac1{(3n+1)^2}\right)[/tex]
Recall the Fourier series we used in an earlier question [27217075]; if [tex]f(x)=\left(x-\frac12\right)^2[/tex] where 0 ≤ x ≤ 1 is a periodic function, then
[tex]\displaystyle f(x) = \frac1{12} + \frac1{\pi^2} \sum_{n=1}^\infty \frac{\cos(2\pi n x)}{n^2}[/tex]
[tex]\implies \displaystyle f(x) = \frac1{12} + \frac1{\pi^2} \left(\sum_{n=0}^\infty \frac{\cos(2\pi(3n+1)x)}{(3n+1)^2} + \sum_{n=0}^\infty \frac{\cos(2\pi(3n+2)x)}{(3n+2)^2} + \sum_{n=1}^\infty \frac{\cos(2\pi(3n)x)}{(3n)^2}\right)[/tex]
[tex]\implies \displaystyle f(x) = \frac1{12} + \frac1{\pi^2} \left(\sum_{n=0}^\infty \frac{\cos(6\pi n x + 2\pi x)}{(3n+1)^2} + \sum_{n=0}^\infty \frac{\cos(6\pi n x + 4\pi x)}{(3n+2)^2} + \sum_{n=1}^\infty \frac{\cos(6\pi n x)}{(3n)^2}\right)[/tex]
Evaluate f and its Fourier expansion at x = 1/2 :
