Answer:
(5,53°) or (5,53.13010235°) if you want an exact value.
Step-by-step explanation:
Polar coordinate is in [tex]\displaystyle{(r,\theta)}[/tex] form and rectangular coordinate is in [tex]\displaystyle{(x,y)}[/tex] form.
To convert from rectangular coordinate to polar coordinate, you’ll have to know that:
[tex]\displaystyle{x=r\cos \theta}\\\displaystyle{y=r\sin \theta}[/tex]
Above is crucial when it comes to converting from rectangular coordinate to polar coordinate, or other way around. The thing is to convert from rectangular to polar, you’ll also have to know radius too which you can find by:
[tex]\displaystyle{r=\sqrt{x^2+y^2}}[/tex]
We know that x = 3 and y = 4, substitute in the formula:
[tex]\displaystyle{r=\sqrt{3^2+4^2}}\\\\\displaystyle{r=\sqrt{9+16}}\\\\\displaystyle{r=\sqrt{25}}\\\\\displaystyle{r=5}[/tex]
We know that radius is 5. We will have to find the theta next, first substitute in the conversion:
[tex]\displaystyle{3=5\cos \theta}\\\displaystyle{4=5\sin \theta}[/tex]
Since this can generally be found through calculator as it’s not a part of special triangle - can be found using hand method - The approximation of both theta’s values are 53°.
Hence, the polar coordinate is (5,53°) or (5,53.13010235°) if you want an exact value.

2. Gerald was given the following problem to solve for the length of the “?”. He has made a mistake in his work. Identify and describe how he made his mistake. Then, solve the problem correctly.
Answer:
x = 18.7
Step-by-step explanation:
Gerald's answer is almost correct.
He just needs to switch the 14 and the x.
it should be
24/x = 18/14
solve for x by cross multiplication
18x = (24)(14)
18x = 336
x = 18.7

Identify the zeros of the quadratic function.
x=1 and x= -3
x= -1 and x=3
y= -1 and y= -3
y= -1 and y=3
Answer:
The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.

Answer:
x = 5.25
Step-by-step explanation:
If I am understanding the question correctly, you are asking to find x when 4x=21? If this is the case, then all you must do is divide 21 by 4, then you get 5.25.

Which is an equation of the line that passes through the points (-6, 3) and (2, 7)?
Answer:
slope: 1/2
y: intercept: (0;6)
so B
The equation of the line is y = x/2 + 6 which passes through the points (-6, 3) and (2, 7) option (B) is correct.
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
It is given that:
The line that passes through the points (-6, 3) and (2, 7)
The equation of the line:
y - 7 = (7 - 3)/(2 + 6)[x - 2]
The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
y = (1/2)x - 1 + 7
y = x/2 + 6
Thus, the equation of the line is y = x/2 + 6 which passes through the points (-6, 3) and (2, 7) option (B) is correct.

Henry buys a softball for $16 plus a 9% tax. Ella buys a pair of shoes for $17 plus a 9% tax. Enter the difference in the amount
Henry and Ella paid, including tax. Round your answer to the nearest cent.
Answer:
The different of the tax was 0.09 cents
Step-by-step explanation:
1. Find how much the tax was
Henry = (16/100) (9) = (0.16) (9) = $1.44
Ella = (17/100) (9) = (0.17) (9) = $1.53
2. Subtract the taxes
1.53 - 1.44 = 0.09 cent
