Answer: C. 8
When we have two chords intersecting inside a circle, the products of the lengths of the segments are equal to one another. This means that for the given circle, we have the following:
10 * 4 = 5 * x
We can solve for x by multiplying 10 by 4, which is 40, and then dividing by 5, to isolate x, which is 8.

Answer:

Slope-intercept form:
y = mx + bGiven line has a slope of m = 1/5.
Parallel lines have equal slopes, so the line we are looking for is:
y = (1/5)x + b and passing through point P(3,8).Substitute the coordinates and slope and find b:

The value of the variable 'x' is calculated by solving equation of the line by using slope value is: x = 3
What is slope of a line?
The slope of a line explain the steepness of the line segment. It is ration of the coordinates of the y-axis and the vertical coordinates of the x-axis. Depending upon the slope value, it is classified as whether lines are parallel or perpendicular.
According to the question, the given parameters for the line segment is as written below:
Slope of a line = (-4) and the coordinate points = (-1, 7)(x,-9): (x1 = -1; y1 = 7)
Now, by using standard equation for the line segment: y = mx + c
where, 'm' is the slope; c is the y-intercept; (x, y) are coordinates
Substituting given values that is slope and y-intercept in the standard equation, we get:
y = mx + c
⇒ 7 = (-4)(-1) + c
⇒ c = 7 - 4 = 3
Therefore, the value of the y-intercept is: c = (3)
Equation of the line by substituting the value of the y-intercept as well as slope value in another equation whose coordinates are (x, -9):
-9 = (-4)x + (3) ⇒ -12 = -4x ⇒ x =3
Hence, the value of the variable 'x' is calculated by solving equation of the line by using slope value is: x = 3

The value of P = $5000, r = 3.6%/4 = 0.9%, n = 4n and amount after 10 years is $5450.
Compound interest may be defined as the interest which can be applied by any institution on any individual in which the interest amount after a year becomes principle for the next year. The formula for compound interest is given as A = P(1 + r/n) ^ nt where A is the amount, P is the principle, r is the interest rate, n is compounding frequency and t is the time. If compounded quarterly the principle will be same as in the question that is $5000, the interest rate will be divided by 4 that is r = 0.9% and the compounding frequency will be 4 times that is 4n. Now, we need to find the amount after 10 years that is t = 10 years. The amount will be
A = P(1 + r/4n) ^ 4nt
A = 5000(1 + 0.9/100×4×12) ^4×12×10
A = 5000(1.09)
A = $5450 which will be amount after 10 years.

What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.
As per the given graph of a random function,
The value of f(x) decreasing when x is increasing is the interval on which we can say that function is decreasing.
If we look at the extreme left of the graph and come towards the right then the curve is going downward till x = -5.
Therefore, in interval (-∞, -5] function is decreasing.
The function is again going down in intervals [-2,2].
Therefore in inteval (-∞, -5] ∪ [-2, 2] the function is decreasing.

Answers
We need to determine if the statements are true or false.
In order to do so, we need to pay attention to the following notations:
[tex]\begin{gathered} (\sin x)^{-1}=\frac{1}{\sin x} \\ \\ \sin^{-1}x=\text{ inverse function of }\sin x \end{gathered}[/tex]The same notations apply to cosine and tangent functions.
The inverse f⁻¹(x) is the function such that:
[tex](f^{-1}\circ f)(x)=f^{-1}(f(x))=x[/tex]Thus, we have:
[tex]\cos^{-1}(\cos(\frac{15\pi}{6}))=\frac{15\pi}{6}[/tex]Therefore, statement g. is true.
In order to show that statements f. and h. are false, let's see what happens for x = 1/2:
[tex]\begin{gathered} \frac{\sin^{-1}(\frac{1}{2})}{\cos^{-1}(\frac{1}{2})}=\frac{\frac{\pi}{6}}{\frac{\pi}{3}}=\frac{3}{6}=0.5\text{ \lparen no units\rparen} \\ \\ \tan^{-1}(\frac{1}{2})\cong0.46\text{ \lparen rad\rparen} \\ \\ \Rightarrow\frac{\sin^{-1}(\frac{1}{2})}{\cos^{-1}(\frac{1}{2})}\ne\tan^{-1}(\frac{1}{2}) \end{gathered}[/tex][tex]\begin{gathered} \sin^{-1}(\frac{1}{2})=\frac{\pi}{6}\cong0.52 \\ \\ \frac{1}{\sin(\frac{1}{2})}\cong2.09 \\ \\ \Rightarrow\sin^{-1}(\frac{1}{2})\ne\frac{1}{\sin(\frac{1}{2})} \end{gathered}[/tex]Answer:
f. False
g. True
h. False
Notice that we can correct the statements f. and h. by using the correct notation:

[tex]\begin{aligned}\textsf{Volume of a rectangular prism}&=\sf width \times length \times height\\\\\implies \textsf{Volume of tank}&=\sf 5 \; ft \times 3\; ft \times 4 \; ft\\& = \sf 15\;ft^2 \times 4\;ft\\& = \sf 60 \; ft^3\end{aligned}[/tex]
To find the maximum number of fish that can be put in the tank, divide the found volume of the tank by the given volume of water required per fish:
[tex]\begin{aligned}\textsf{Maximum number of fish}&=\textsf{Volume of tank} \div \textsf{Water per fish}\\& = \sf 60\;ft^3 \div 1.5 \; ft^3\\& = \sf 60 \div 1.5\\& = \sf 40\end{aligned}[/tex]

To find:
The value of x
Parallelogram ABCD,
∠A and ∠B are two adjacent sides
Properties of a parallelograms
Two opposite sides are parallelogram are equal and parallel to each other.
So, the adjacent sides are supplementary angles i.e. sum is 180°.
The opposite angles are equal.
Now,
∠A + ∠B = 180°
⇒ 3x + (5x + 12) = 180
⇒ 3x + 5x + 12 = 180
⇒ 8x + 12 = 180
⇒ 8x = 180 - 12
⇒ 8x = 168
⇒ x = 168 ÷ 8
⇒ x = 21
Thus,
The value of x = 21
The angles are
∠A = 3x = 3 * 21 = 63°
∠B = (5x + 12) = (5 * 21 + 12) = 105 + 12 = 117°
As opposite angles are equal so
∠A = ∠C = 63°
∠B = ∠D = 117°

What is meant by Pythagoras connection?The Pythagorean theorem, or Pythagorean theorem, explains the relationship between the three sides of a right-angled triangle. The square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle, according to Pythagoras' theorem.
From the diagram, the formation is a rectangle.
Use the coordinate points to find the measurements of each side.
Side length AD = Side length BC
Apply the Pythagoras connection to find length BC as;
a² + b²= c² where a=2 cm and b = 4 cm and c =BC
2² + 4² = c²
4+16 = c²
20 = c²
c= √20 = 4.4721
Length BC = Length AD = 4.5 cm
Side length AB = Side length DC
Apply the Pythagoras connection to find the length DC as;
a² + b²= c² where a=6 cm and b = 3 cm and c =DC
6² + 3² =c²
36 + 9 = c²
45 = c²
√45 = c
c= 6.7082
c = DC = 6.7 cm
Now you have the dimensions of the rectangle as;
Length = 6.7 cm and width = 4.5 cm
The perimeter will be ;
P= 2{l +w} --------- where l is length and w is width and P is the perimeter of the rectangle
P=2{6.7 + 4.5}
P=2{11.2}
P= 22.4 cm
The area will be ;
A= l*w
A= 6.7 * 4.5 = 30.15 = 30.2 cm²

B) a = 1, h = –1, k = 6
C) a = 1, h = 0, k = 6
D) None of the choices are correct.
Answers
Answer:
N^2+6 is in standard form, which is in ax^2+bx+c,
in order to get it to vertex form, which y=a(x-h)^2+k, we need to find the vertex, through x=-b/2a, in this case:
x=-0/2(1)=0, so h=0, then plug 0 in for n,
0^2+6=6,
which makes k=6,
therefore, the answer is c.
as for a, the value of a is constant in all forms, whether standard, vertex or factored, making a=1

Ten bags of beans cost GH¢350.00.
a)Find the cost of 6 bags.
b)Find the cost of 11 bags.
c)How many bags can GH¢245.00
buy?
With solutions
Answers
The cost of 6 bags is GH¢ 210
The cost of 11 bags is GH¢ 385
GH¢245.00 can buy 7 bags
Tens bags cost GH¢350.00
one bags cost = 350/10
= 35
The cost of 6 bags can be calculated as follows
1 bag= 35
6= x
cross multiply both sides
x= 35×6
x= 210
The cost of 11 bags can be calculated as follows
1= 35
11= y
cross multiply
y= 35 × 11
= 385
The number of bags GH¢245.00 will buy can be calculated as follows
1 = 35
x= 245
cross multiply both sides.
35x= 245
x= 245/35
x= 7
Hence GH¢245.00 can buy 7 bags, 6 bags cost GH¢210 and 11 bags cost GH¢ 385

Calculate Sample Variance for the following data collection: 10, 11,12, 13, 14, 18.
Answers
To calculate the variance follow these steps:
1. Work out the Mean
2. Then for each number: subtract the Mean and square the result .
3. Then work out the average of those squared differences.
The data are 10, 11, 12, 13, 14, 18
The first step find the mean
The mean = sum of data/number of data
The sum = 10 + 11 + 12+ 13 +14 + 18 = 78
The number =
