The requried ratio of boys in the club to girls is given as 7/9 or 7:9. Option A is correct.
What is the Ratio?The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Here,
The conservation club has 32 members. There are 18 girls in the club.
Number of boys = 32 - 18 = 14
Ratio of boys to girls = number of boys / number of girls
= 14 / 18 = 7/9
Thus, the requried ratio of boys in the club to girls is given as 7/9 or 7:9. Option A is correct.

Jim spent a total of $125.15 for the 130 miles he traveled in one day at the $14.95 base fee.
what is equation ?A mathematical equation is a formula that connects two statements using the equal sign (=) to signify equivalence. A mathematical statement demonstrating the equality of two mathematical expressions is the definition of an equation in algebra. For instance, the variables 3x + 5 and 14 are separated by an equal sign in the equation 3x + 5 = 14. Mathematically, the connection between two phrases on either side of a letter is stated. The symbol doubles as the sole variable most of the time. for illustration, 2x - 4 = 2.
given
per mile the cost is $0.85
Base fee is 14.95
0.85x+14.95= 125.15
0.85x=125.15 - 14.95
0.85x = 110 . 92
x= 110 . 92 / 0.85
x= 130. 49

NEED SOMEOEN THAT KNOWS PRE CALC The endpoints of a diameter of a circle are (7,−4) and (−3,2).
What is the equation of the circle in standard form?
Enter your answer by filling in the boxes. Enter any fractions in simplified form.
(x-2)² + ( y + 1)² = 34 is the equation of the circle in standard form.
What is the short definition of a circle?
To put it simply, a circle is a spherical shape without any edges or line segments. In terms of geometry, it has the shape of a closed curve.
The circle's points are set apart from the center by a predetermined amount.
The endpoints of the diameter (7,−4) and (−3,2)
the center of the circle is the midpoint of the diameter.
So, the coordinates of the center
(h,k) = ( 7 + (-3)/2 , -4 +2/2)
= ( 4/2 , -1 )
= ( 2 , -1 )
the radius of the circle is just half of the length of the diameter.
So, r = 1/2√(-3 -7 )² + ( 2 - (-4))²
= 1/2√(10)² + ( 2 +4 )²
= 1/2√100 + 36
= 1/2√136
= √136/2
= 2√34/2
= √34
substitute the values of h, k, and r into the standard equation of the circle
( x-h)² + ( y-k)² = r²
( x - 2)² + ( y -(-1))² = (√34)²
(x-2)² + ( y + 1)² = 34

A student graphed f(x) = x and g(x) = f(x) - 5 on
the same coordinate grid. Which statement
describes how the graphs of f and g are related?
A The graph of f is shifted 5 units up to create the
graph of g.
B The graph of f is steeper than the graph of g.
C The graph of f is shifted 5 units down to create
the graph of g.
D The graph of f is less steep than the graph of g.
The statement (c) describes that the graph of f is shifted 5 units down to create the graph of g. The solution has been obtained using the concept of vertical translation.
What is translation?
Translation is the act of moving a shape or a figure from one position to another. It is classified into two types:
Horizontal Translation: This describes the movement of a function graph to left or right.Vertical Translation: This describes the movement of a function graph upward or downward.Now, for a function f(x) we define a vertical translation of N units as:
g(x) = f(x) + N
If N is positive, the translation is upwards.
if N is negative, the translation is downwards.
We are given g(x) = f(x) - 5
This shows that N is negative and therefore, there is translation of 5 units downwards.
Hence, the graph of f is shifted 5 units down to create
the graph of g.

What is an equation of the line that passes through the point (6,-4)(6,−4) and is perpendicular to the line 2x-y=52x−y=5?
The line that connects the coordinates (6, 4) and is perpendicular to the line 2xy=5 has the equation =y=1/2x-1.
What are straight-line equations?The general equation for every straight line is y = mx + c, where m is the gradient (or degree of steepness) of the line and c is the y-intercept (the point in which the line crosses the y-axis).
The variables x and y are related to coordinates on the line in the linear equation y = mx + c.
The formula y = mx + c yields a result for y when we enter a value for x.
As y depends on the value of x, it follows that x is an independent variable and y is a dependent variable.
According to our question-
a line equation that is perpendicular to the line 2xy=5 and passes through the point (6, 4)
The slope of the given equation 2x-y=5 is first determined.

What is Distance formula?
The distance formula is a mathematical formula used to determine the distance between two points in a plane. The formula is:
d = √((x2 - x1)² + (y2 - y1)²)
"C" and "D" are points in a two-dimensional coordinate system. C is represented by the coordinates (-1, 11) and D is represented by the coordinates (7, -4).
The difference between these two points is the distance between them, which can be calculated using the distance formula:
√((x2 - x1)² + (y2 - y1)²)
Where x1, y1 are the coordinates of point C and x2, y2 are the coordinates of point D.
Substituting the values, we get:
√((7 - (-1))² + (-4 - 11)²) = √((8)² + (-15)²) = √(64 + 225) = √289
Hence, the difference between point C and D is √289 units.

Evaluate the iterated integral. 1 0 s5 cos(s6) dt ds 0

Here we have to evaluate the given iterated integral.
The definite integral of a real-valued function f(x) with respect to a real variable x on an interval [a, b] is expressed as,
[tex]\int\limits^a_b f({x} )\, dx[/tex] = f(b) - f(a)
Where,
a = Lower limit
b = Upper limit
f(x) = Integrand
dx = Integrating agent
Thus, [tex]\int\limits^_[/tex] ab f(x) dx is read as the definite integral of f(x) with respect to d x from a to b.
Indefinite integrals are implemented when the boundaries of the integrand are not specified.
[tex]I[/tex] = [tex]\int\limits^1_0[/tex] [tex]\int\limits^s_0[/tex] cos ([tex]s^{6}[/tex] ) [tex]dt ds[/tex]
Integrate the given iterated integral.
We get:
= [tex]\int\limits^1_0[/tex] cos ([tex]s^{6}[/tex] ) ([tex]\int\limits^5_0dt[/tex] ) ds
= [tex]\int\limits^1_0[/tex] cos ([tex]s^{6}[/tex] ) [t][tex]0 to s^{5}[/tex] ds

= [tex]\int\limits^1_0[/tex] [tex]s^{5}[/tex]cos ([tex]s^{6}[/tex] )ds
Then,
[tex]s^{6}[/tex] = t when s = 0
[tex]\frac{dt}{ds}[/tex] = 6[tex]s^{5}[/tex] t = 0
[tex]\frac{dt}{6}[/tex] = [tex]s^{5}[/tex] ds when s = 1..... t = 1
Replace the assumed terms.
Then we get:
[tex]I[/tex] = [tex]\int\limits^1_0[/tex] cos(t) [tex]\frac{dt}{6}[/tex]
[tex]I[/tex] = [tex]\frac{1}{6}[/tex] [tex]\int\limits^1_0[/tex] cos(t) dt
[tex]I[/tex] = [tex]\frac{1}{6}[/tex] [sin(t)][tex]0to1[/tex]
[tex]I[/tex] = [tex]\frac{1}{6}[/tex] [ sin(1) - sin(0) ]
[tex]I[/tex] = [tex]\frac{sin(1)}{6}[/tex]

14) Probability that exactly 5 of the students will graduate is 0.1636.
15) Probability that atleast 8 of the students will graduate is 0.2405.
We have , In a college,
The freshmen graduate enters = 64%
Probability of sucess , p = 64% = 0.64
Probability of failure , q = 1 - 0.64 = 0.36
Randomly selected entering = 10 , i.e, n = 10.
This follows a Binomial probability distribution with the parameters, n = 10 and p = 0.64.
Using Binomial probability formula,
P(X = x) = ⁿCₖ pᵏ (1 - p)ⁿ⁻ᵏ
(14) Probability that exactly 5 of the students will graduate = P(x = 5),
P( x = 5) = ¹⁰C ₅ (0.64⁵) (0.36⁵)
= 0.1636
15) Probability that at least 8 of the students will graduate, P(x ≥8) = P(X= 8) + P(X= 9) + P(X= 10)

A factor is a number that divides another number, leaving no remainder. In other words, if multiplying two whole numbers gives us a product, then the numbers we are multiplying are factors of the product because they are divisible by the product.
There are two methods of finding factors: multiplication and division. In addition, rules of divisibility may also be used.
