In the given figure, ABCD is a square of side 14 cm. Find the area of the shaded region. Take π = 2²/2)
Answer:
Step-by-step explanation:
Area of shaded region = Area of Square ABCD− Area of 4 quadrants of circle
Side of square =14cm
Area of Square =(side)
2=(14) 2=196cm 2Radius of circle = half of the side of square = 214=7cmArea of quadrant of circle = 41πr 2

If you want to bisect a line segment, what would be the order of the following steps?
If you are aware of the line's length or have access to a ruler, bisecting (or cutting in half) a line is not difficult. However, you can still cut the line in half with a straightedge and compass even if you don't know how long it is.
Draw the section of the line you need to divide. You must use a straightedge to create the line segment if it is not already present. Put the compass needle on either terminal to accomplish this. Approximately half of the length should be covered by the compass when it is opened.
Using the compass, aim to keep the needle on the endpoint and refrain from changing the compass's setting. To do this, position your straightedge on the intersection of the arcs above the line and line them up with the intersection below the line. The line is bisected at a 90-degree angle by the line you draw connecting the two arc intersections.

The values of x and y that makes quadrilateral ABCD a parallelogram are x = 9 and y = 3
How to determine the values of x and y?The figure that completes the question is added as an attachment
The opposite sides of a parallelogram are congruent
This means that
5x - 20 = 7x - 38
4y + 11 = 6x - 31
So, we have
5x - 20 = 7x - 38
Collect the like terms
7x - 5x = 38 - 20
Evaluate the like terms
2x = 18
Divide through by 2
x = 9
Substitute x = 9 in 4y + 11 = 6x - 31
So, we have
4y + 11 = 6 x 9 - 31
Evaluate the product
So, we have
4y + 11 = 23
This gives
4y = 12
So, we have
y = 3
Hence, the values of x and y that makes quadrilateral ABCD a parallelogram are x = 9 and y = 3

Let f(x)=7 x+5 and g(x)=x² . Perform each function operation and then find the domain of the result.
(f+g)(x)
Function operations are the rules we use to solve functions. There is a specific way to deal with function addition, multiplication, and division.
x² + 7x + 5 is the domain of all real numbers.
What is meant by function operation?Function operations are the rules we use to solve functions. There is a specific way to deal with function addition, multiplication, and division.
Let the two functions be f and g then f(x) = 7x + 5 and g(x) = x².
we have to calculate (f + g)(x)
Which is equivalent to:
(f + g)(x) = f(x) + g(x)
Taking the two functions and substituting them into this expression, we get,
f(x) + g(x) = (7x + 5) + (x²)
simplifying the above function, we get
f(x) + g(x) = x² + 7x + 5
Therefore, (f + g)(x) = x² + 7x + 5.
We must also determine the domain of the new function. However, because this is a second-order function with no denominators, logarithms, or roots, there are no restrictions on the value of x; thus, the domain is all real numbers.

What is the value of each logarithm?
a. log₅125
The answer for the given logarithmic function is 3
Logarithm is a mathematical tool used to make high value calculations simple.
It is the exponent to the power of which a number must be raised to give a certain result.
Some of the important formulas in logarithm are:
loga[tex]b^{n}[/tex] where a is considered as base of the logarithm and b is the argument
is given as nlogab
when base and the argument is same , log is given as 1
logabc where a is the base is given as logab+logc
loga b/c where a is the base is given as logab-logac
Now it is given to us to find the value of log₅125
where 5 is the base and 125 is the argument
125 = 5x5x5 which is [tex]5^{3}[/tex]
hence 125 can be written as 5^3
Thus the logarithmic function becomes
log₅125=log₅[tex]5^{3}[/tex]
thus it can be written as3log₅5
Now we know that log₅5 can also be written as log5/log5
And hence log5/log5 becomes 1
Thus 3log₅5 = 3*1 =3
Hence the answer to the given logarithm is 3

Melinda is at tennis practice. She hits 32 tennis balls a minute. She hit 45 tennis balls before practice. If Melinda hit a total of 1,645 tennis balls, how long was she at practice?
If Melinda hit a total of 1,645 tennis balls and she hits 32 balls per minute, it means she has been in the tennis practice for 50 minutes
How many of the hits of 1645 are attributable to only practice?
Out of the 1645 tennis balls so far hit by Melinda only 1,600 are attributable to the tennis practice because she has already hit 45 tennis balls before the tennis practice commenced
number of tennis balls in tennis practice=1645-45

b. x² + 2 x-8 / x²-5 x+6
The required simplification of rational expression is (4 + x) / (x - 3).
What is a rational number?
Any real number that can be represented in the form of p/q, where q is not equal to 0 is called a rational number. The decimal expansion of rational numbers is terminating and repeating.
Simplifying the rational expression: x² + 2x - 8 / x² - 5x + 6
Given a rational expression,
x² + 2x - 8 / x² - 5x + 6
On simplifying, we get,
For numerator, x² + 2x - 8: (x - 2)(x + 4)
For denominator, x² - 5x + 6: (x - 2)(x - 3)
Now, x² + 2x - 8 / x² - 5x + 6 = (x - 2)(4 + x) / (x - 2)(x - 3)
= (4 + x) / (x - 3)
Restriction is that the denominator, x - 3 should not be 0.
Hence, the required simplification of rational expression is (4 + x) / (x - 3)

[tex]\textsf{e)} \quad v = -292.242\:\: \sf ft/s \:\: (3\: d.p.)[/tex]
Step-by-step explanation:
Given:
[tex]s(t)=-16t^2+v_0t+s_0[/tex]
Part (a)If v₀ is the initial velocity, and s₀ is the initial position:
[tex]\implies v_0=0[/tex]
[tex]\implies s_0=1362[/tex]
Therefore:
[tex]\begin{aligned}\textsf{Position function}: \quad s(t) & =-16t^2+0+1362\\ \implies s(t) & = -16t^2+1362 \end{aligned}[/tex]
[tex]\begin{aligned}\textsf{Velocity function}: \quad v(t)&=s\:'(t)\\ \implies v(t) &=-32t\end{aligned}[/tex]
Part (b)Average velocity is the change in displacement divided by the change in time:
[tex]\overline{v}=\dfrac{s(t_2)-s(t_1)}{t_2-t_1}[/tex]
Given interval: 1 ≤ t ≤ 2
[tex]\implies t_1=1[/tex]
[tex]\implies t_2=2[/tex]
Find the values of s(t) at t = 1 and t = 2:
[tex]\implies s(1)=-16(1)^2+1362=1346[/tex]
[tex]\implies s(2)=-16(2)^2+1362=1298[/tex]
Substitute the values into the formula:
[tex]\overline{v}=\dfrac{s(2)-s(1)}{2-1}=\dfrac{1298-1346}{2-1}=-48\:\: \sf ft/s[/tex]
Part (c)To find the velocity at t = 1 and t = 2, substitute these values into the velocity function found in part (a):
[tex]\implies v(1)=-32(1)=-32\:\: \sf ft/s[/tex]
[tex]\implies v(2)=-32(2)=-64\:\: \sf ft/s[/tex]
Part (d)The time required for the coin to reach ground level is when s(t) = 0:
[tex]\begin{aligned}s(t) & = 0\\-16t^2+1362 & = 0\\16t^2 & = 1362\\t^2 & = 85.125\\t & = \sqrt{85.125}\\t & = 9.226\: \sf s\:\:(3\:d.p.)\end{aligned}[/tex]
Part (e)To find the velocity of the coin at impact with the ground, substitute the found value of t from part (d) into the equation for velocity found in part (a):
[tex]\begin{aligned}v(t) & = -32t\\\implies v(\sqrt{85.125}) & = -32(\sqrt{85.125})\\ v & =-295.242\:\: \sf ft/s\:\:(3\:d.p.)\end{aligned}[/tex]
Note: I have used the non-rounded value of t from part (d) for accuracy.
