Answer:
Step-by-step explanation:
Yes, by side 6cm, 8cm, 10cm be a right angle triangle.
explain, by pythagoras theorem,
(hypotenuse)^2 = (perpendicular)^2 + (base)^2
=> (10)^2 = (6)^2 + (8)^2
=> 100 = 36 + 64
=> 100 = 100
so, it is verifying the phythagoras theorem, hence it will form a right angle triangle with side 6cm, 8cm, and 10cm.
Use a double integral to find the area of the region. The region inside the circle (x − 2)2 + y2 = 4 and outside the circle x2 + y2 = 4
The area of the region inside the circle (x − 2)^2 + y^2 = 4 and outside the circle x^2 + y^2 = 4 is given by
Area = ∬R dA where R is the region we're trying to find the area of.
We can find the area of the region by subtracting the area of the smaller circle from the area of the larger circle.
The area of the larger circle is:
Area = ∬R dA = ∬((x − 2)^2 + y^2 <= 4) dA = π*4 = 4π
The area of the smaller circle is:
Area = ∬((x^2 + y^2) <= 4) dA = π*4 = 4π
Therefore, the area of the region inside the circle (x − 2)^2 + y^2 = 4 and outside the circle x^2 + y^2 = 4 is
Area = 4π - 4π = 0
The area of the region is 0 square units.

Caleb is going to invest in an account paying an interest rate of 6% compounded daily. How much would Caleb need to invest, to the nearest cent, for the value of the account to reach $1,900 in 5 years?
Caleb would need to invest $1,764.69 to the nearest cent, for the value of the account to reach $1,900 in 5 years with an interest rate of 6% compounded daily.
What is compound interest?
Compound interest is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods. It is different from simple interest, which is calculated only on the initial principal.
To find out how much Caleb needs to invest, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A = the future value of the investment
P = the principal or initial investment
r = the annual interest rate (expressed as a decimal)
n = the number of times per year that interest is compounded
t = the number of years the investment will be held
We know that Caleb wants the future value of the investment to be $1,900 in 5 years and interest is compounded daily with an annual rate of 6%. So we can set up the equation as:
A = P(1 + r/n)^(nt)
1900 = P(1 + 0.06/365)^(365*5)
To solve for P, we can use a calculator to get the result:
P = $1,764.69
Hence, Caleb would need to invest $1,764.69 to the nearest cent, for the value of the account to reach $1,900 in 5 years with an interest rate of 6% compounded daily.

On solving the provided question we can say that by unitary method number of extra copies made by machine 2 = 192 – 180 = 12
What is unitary method ?
The unit technique is an approach to problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value. The unit method, to put it simply, is used to extract a single unit value from a supplied multiple. For instance, 40 pens would cost 400 rupees, or the price of one pen.
In 8 minutes, Machine 1 produces 240 copies. In 5 minutes, machine 2 produces 240 copies. The rates of operation for each machine are constant.

If U and T are the midpoints and the distance between S and R is 56 miles, what is the distance from U to T ?
The final distance from U to T is 112 miles.
Since U and T are the midpoints of SR and ST respectively, we know that SU and RT are congruent and have the same length.
We need to find the overall displacement of U&T.
Also, we know that the distance between S and R is 56 miles.
Therefore, the distance from U to T is equal to twice the distance from S to U which is 2 * (distance from S to R) = 2 * 56 = 112 miles.
Therefore, The final distance from U to T is 112 miles.

what is slope intercept?In mathematics, the intersection point is the place on the y-axis where the slope of the line crosses. a place where the y-axis crosses on a line or curve. Y = mx+c, where m stands for the slope and c for the y-intercept, is used as the equation for the straight line to show this. The slope (m) of the line and its y-intercept (b) are emphasised in the equation's intercept form. When an equation has the intercept form (y=mx+b), the slope is m and the y-intercept is b. Some equations can also be rewritten such that they seem to be slope intercepts. If y=x is rewritten as y=1x+0, for instance, the slope and y-intercept are both changed to 1.
Given, x - intercept of a line is 6
so,
The line will pass through the point (6, 0)
Also given. the y - intercept ofthe line is —4 c = —4

Given equation
y²=x
This is an equation of a parabola. graph{y^² = x [-10, 10, -5, 5]}
For finding the tangent to the equation, we first differentiate it.
The goal here is to find the value of dy/dx which will give the slope of the tangent to the parabola.
So,
[tex]\frac{d}{dy}(y^2)=\frac{dx}{dy} \\\\2y=\frac{dx}{dy} \\\\\frac{1}{2y} =\frac{dx}{dy} \\\\[/tex]
Now, we want to evaluate the slope at the given point. So substituting y we get,
[tex]\frac{1}{18} =\frac{dx}{dy}[/tex]
This is the slope of the tangent.
It passes through (81,9) [as per in the question]
The general equation of a line is y=mx+c
m is the slope of the line.
For the line/tangent that we got
[tex]m=\frac{dy}{dx}[/tex]
[tex]y=\frac{x}{18} +C[/tex]

Isosceles triangle ABC contains angle bisectors segment BF, segment AD, and segment CE that intersect at X.
The measure of angle ∠CXA is 134°
What is the Isosceles triangle?
In geometry, an isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case.
Triangle ABC is an isosceles triangle where AB = BC
∵ AB = BC
- The base angles in the isosceles triangle are congruent
∴ m∠BAC = m∠BCA
∵ m∠ BCA = 46° ⇒ given
∴ m∠ BAC = 46°
- The sum of the measures of the interior angles in any triangle is 180°
∵ m∠BAC + m∠BCA + m∠ABC = 180°
- Substitute the values of angle BAC and BCA in the equation above
∴ 46 + 46 + m∠ABC = 180
∴ 92 + m∠ABC = 180
- Subtract 92 from both sides
∴ m∠ABC = 88°
- BF, AD, and CE are bisectors segments of angles B, A, and C and they are intersected at point X
∵ CE bisects ∠BCA
∵ X ∈ CE
∴ m∠XCA = 1/2 m∠BCA
∴ m∠XCA = 1/2 (46) = 23°
∵ AD bisects ∠BAC
∵ X ∈ AD
∴ m∠XAC = 1/2 m∠BAC
∴ m∠XAC = 1/2 (46) = 23°
- In Δ AXC
∵ m∠XAC = 23° ⇒ proved
∵ m∠XCA = 23° ⇒ proved
∵ m∠CXA + m∠XAC + m∠XCA = 180° ⇒ interior angles of Δ
Substitute the values of angles XAC and XCA
∴ m∠AXC + 23 + 23 = 180
∴ m∠CXA + 46 = 180
- Subtract 46 from both sides
∴ m∠CXA = 134°
Hence, The measure of angle ∠CXA is 134°.

Three fruits, such as an apple, an orange, and a pear, for instance, can be combined into three different pairs: an apple and a pear, an apple and an orange, or a pear and an orange. A k-combination of a set S is officially defined as a subset of S's k unique elements. So, if and only if each combination contains the same elements, two combinations are said to be identical.

How do you use table formulas?
There are different tables used in mathematics i.e. logarithmic tables, semi-logarithmic tables, exponential tables, trigonometric function tables, etc.
The tables are provided with data that is needed for the calculations. For example: if the value of Sin 45° needs to be found then we have to move to the table of Sin Θ and then follow the rows of angles where the value of Sin 45° can be obtained. Similarly, the values of other functions can be found in this way. However, the trigonometric table also provides the relation between two functions like Tan Θ= [tex]\frac{SinΘ}{CosΘ}[/tex].

I don’t understand, someone please help
a)
The rate of change is of 3, hence the hourly cost is of $3.The initial value is of 3.50, hence the skate rental fee is of $3.50.b) The slope-intercept definition of the linear function is given as follows:
y = 3x + 3.50.
How to define the linear function?The slope-intercept definition of a linear function is given as follows:
y = mx + b.
In which:
m is the slope, representing the rate of change of the output variable relative to the input variable.b is the intercept, representing the value of y when x assumes a value of zero.Two points on the linear function in this problem are given as follows:
(2, 9.50) and (5, 18.50).
The slope is given by the division of the change in y by the change in x, hence:
m = (18.50 - 9.5)/(5 - 2)
m = 9/3
m = 3.
Representing the hourly charge.
Hence:
y = 3x + b.
When x = 2, y = 9.50, hence the intercept b, representing the rental fee, is given as follows:
9.5 = 3(2) + b
b = 3.50.
Meaning that the function is defined as follows:
y = 3x + 3.5.
