The intersection point of the circle and the line is at-(2.68, 7.36).
What is defined as the equation of circle?A circle is a confined curve drawn from a fixed point known as the centre, with all points on the curve sharing the same distance as from centre point. (x-h)² + (y-k)² = r² is the equation for a circle with (h, k) centre and r radius.For the given question;
The equation of the line is; y = 2x + 2 ......eq 1
The centre of the circle (h,k) = (0,2)
The radius of the circle = 6 units.
This is the equation's standard form.
(x - h)² + (y - k)² = r²
Put the values in the formula;
(x - 0)² + (y - 2)² = r²
(x)² + (y - 2)² = r²
Put the value of y from eq 1.
(x)² + (2x + 2 - 2)² = 6²
(x)² + (2x)² = 36
Simplifying;
x = ±6/√5
But the intersection must be in first quadrant.
x = 6/√5 = 2.68
Put the value of x in eq 1.
y = 2x + 2
y = 2×2.68 + 2
y = 7.36
Thus, the coordinates of the intersection of the line and the circle are (2.68, 7.36).

The square root of the product of m and n is √mn.
What are square roots?The value that, when multiplied by itself, returns the original number is called the square root of any number. The sign "√" is used to denote it. There are two square roots for every number, one of which has a positive value and the other a negative value. For instance, the number 4 has 2 and -2 as its two square roots.Any number's square root is represented as the number raised to the power 1/2. The following is the square root formula for the number x.[tex]\sqrt{x} = x^{1/2}[/tex]
To determine the square root of the product of m and n, find the product of m and n and raise the product to the power 1/2.

If rocks along the furnace creek fault have been offset 30 miles over 10 million years, what is the rate of plate motion in cm/year. (Hint: Rate x Time = Distance, and there are 5280 feet in one mile, and 2.54 cm. in one inch.)
Answers
The rate of plate motion in cm/year is equal to 3.3528 × 10⁻³ cm/year.
What is a conversion factor?A conversion factor can be defined as a number that is typically used to convert (change) a number in one (1) set of units to another, either by dividing or multiplying.
Generally speaking, an appropriate conversion factor to an equal value must be used when it is necessary to perform any mathematical conversion.
Conversion:
1 mile = 5280 feet
30 miles = X feet
Cross-multiplying, we have:
X = 30 × 5280
X = 158,400 feet.
Next, we would convert the value in feet to inch and then to cm as follows:
Distance = 158,400/12 = 13,200 inches.
In centimeters (cm), we have:
1 inch = 2.54 cm
13,200 inches = Y cm
Cross-multiplying, we have:
Distance, Y = 13,200 × 2.54
Distance, Y = 33,528 cm.
Now, we can determine the rate of plate motion in cm/year:
Rate = Distance/Time
Rate = 33,528/10,000,000
Rate = 3.3528 × 10⁻³ cm/year.

What is a Set's Cardinal Number?In a finite set, the number of distinct elements is known as the cardinal number. It is written as n(A) and can be read as "the number of set elements."
Let's assume,
U is the set of patients who reported at the hospital on that day.
F is the set of patients who complained of fever.
S is the set of patients who had stomach troubles.
I is the set of injured patients.
The given data can be written as follows:
n(U) = n(F∪S∪I) = 100
n(F) = 70
n(S) = 50
n(I) = 30
n(F∩S) + n(S∩I) + n(I∩F) - 3×n(F∩S∩I) = 44
Using the cardinal number of the union of three sets formula, we get
n(F∪S∪I) = n(F) + n(S) + n(I) - n(F∩S) - n(S∩I) - n(I∩F) + n(F∩S∩I)
100 = 70 + 50 + 30 - (44 + 3×n(F∩S∩I)) + n(F∩S∩I)
100 = 150 - 44 - 2×n(F∩S∩I)
2×n(F∩S∩I) = 106 - 100 = 6
n(F∩S∩I) = 3
Therefore, 3 patients had all the complaints.

What are increasing and decreasing functions?Calculus functions called increasing and decreasing functions have f(x) values that change according to how much x rises or decreases. The behavior of growing and decreasing functions is examined using the derivative of the function f(x). If the value of f(x) grows as the value of x increases, the function is said to be increasing; conversely, if the value of f(x) decreases as the value of x increases, the function is said to be declining.
Like wise in this question we just have to find the d/dx and if it comes out positive then the function is increasing and if it is negative then it is decreasing.

Write a quadratic function for the following characteristics
Answers
Answer:
[tex]y=x^2+6x-16[/tex]
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{6 cm}\underline{Intercept form of a quadratic equation}\\\\$y=a(x-p)(x-q)$\\\\where:\\ \phantom{ww}$\bullet$ $p$ and $q$ are the $x$-intercepts. \\ \phantom{ww}$\bullet$ $a$ is some constant.\\\end{minipage}}[/tex]
Given points on the curve:
(-8, 0)(-6, -16)(2, 0)The x-intercepts of a quadratic function are the points at which the line crosses the x-axis, so when y = 0.
Therefore, the x-intercepts of the given function are -8 and 2.
Substitute these into the intercept formula:
[tex]\implies y=a(x-(-8))(x-2)[/tex]
[tex]\implies y=a(x+8)(x-2)[/tex]
Substitute the other given point (-6, -16) into the equation and solve for a:
[tex]\begin{aligned} y&=a(x+8)(x-2)\\\textsf{When }(-6,-16)\implies -16&=a(-6+8)(-6-2)\\-16&=a(2)(-8)\\-16&=-16a\\\implies a&=1\end{aligned}[/tex]
Therefore, the equation of the function in intercept form is:
[tex]y=(x+8)(x-2)[/tex]
Expand to standard form:
[tex]\implies y=x(x-2)+8(x-2)[/tex]
[tex]\implies y=x^2-2x+8x-16[/tex]
[tex]\implies y=x^2+6x-16[/tex]
Therefore, the quadratic function in standard form is:

Explain why the value of the sine ratio for an acute angle
of a right triangle must always be a positive value less
than 1.
Answers
The sine is defined as the length of the opposite side divided by the length of the hypotenuse, both of which are positive. Since dividing a positive number by a positive number results in a positive number, the sine must be positive.
Also, since the hypotenuse is the longest side of the triangle, the sine is equal to some positive number less than the length of the hypotenuse being divided by the length of the hypotenuse, resulting in a number less than 1.
