Using proportions, it is found that their total monthly payment is of $2,887.37.
What is a proportion?A proportion is a fraction of a total amount, and the measures can be related using a rule of three, which derives from proportional relationships.
Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures, involving operations such as division and multiplication, as they involve unit rates.
For this problem, the payments are given as follows:
$2,165.61 for principal and interest.1/12 = 0.0833 of $6,478.50 for taxes.1/12 = 0.0833 of $2,186 for insurance.Hence:
2165.62 + 0.0833 x 6478.5 + 0.0833 x 2186 = $2,887.37
Their total monthly payment is of $2,887.37.

Q and R are collinear because they lie in the same straight line.
Check whether Q and R are collinear from the given figure.
What are collinear points?Collinear points are the points that lie on the same straight line or in a single line. If two or more two points lie on a line close to or far from each other, then they are said to be collinear, in Euclidean geometry.
Here, Q and R are collinear because they lie in the same straight line.
A set of points in space are coplanar if there exists a geometric plane that contains them all.
Point S is outside the planes, so point S is non-coplanar with either plane.
The intersection of two planes is always a line.
The intersection between the two planes creates a line.
Line l intersects two planes V and W.

Find the center and radius of the circle. x2+y2+4x-6y+4=0
A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre. The centre of circle x2+y2+4x-6y+4=0 is (-2,3) and radius is 3.
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
The given equation is x2+y2+4x-6y+4=0.
The standard form of circle is (x-h)^2+(y-k)^2=r^2
where (h,k) is centre and r is the radius of the circle.
We need to convert x2+y2+4x-6y+4=0 to standard form.
x2+4x+y2-6y=-4.
Add +4 and +9 on both sides
(x2+4x+4)+(y2-6y+9)=-4+4+9
(x2+4x+4)+(y2-6y+9)=9
(x+2)^2+(y-3)^2=3^2
When we compare the above equation with standard form we get
centre (-2,3) and radius is 3.
Therefore the center and radius of the circle x2+y2+4x-6y+4=0 is (-2, 3) and 3.

An angle measures 43.4° less than the measure of its complementary angle. What is the measure of each angle? please answer
The complementary angles are: 66.7° and 23.3°.
What are Complementary Angles?Two angles are said to be complementary if they both have a sum of 90 degrees when added.
Thus, we have the following:
One of the angles is represented as x.
Second angle = x - 43.4
Therefore:
x + x - 43.4 = 90
2x - 43.4 = 90
2x = 90 + 43.4
2x = 133.4
2x/2 = 133.4/2
x = 66.7°
First angle = x = 66.7°
Second angle = 66.7 - 43.4 = 23.3°
Therefore, the complementary angles are: 66.7° and 23.3°.

John waters his 2 1/2 acres of farmland in 1/3 of an hour. What is his speed in acres per hour?
Answer:
7.5 acres per hour
Step-by-step explanation:
1) You know that in 1/3 of an hour John waters 2 1/2, or 2.5, acres of farmland.
2) To get 1 hour we would multiply what John waters in 1/3 of an hour by 3.
2.5acres * 3 = 7.5 acres per hour
3) We multiply by 3 because 1/3 of an hour * 3 = 1 hour
so: 2.5acres * 3 = 7.5 acres per hour
[tex] \rm \int_{ 0}^ {\large\frac{\pi}4} \sqrt{ \tan(x) - \tan {}^{2} (x) } \: dx \\ [/tex]
First substitute [tex]x=\tan^{-1}(y)[/tex] to rewrite the integral as
[tex]\displaystyle \int_0^{\pi/4} \sqrt{\tan(x) - \tan^2(x)} \, dx = \int_0^1 \frac{\sqrt{y-y^2}}{1+y^2} \, dy[/tex]
Now use an Euler substitution, [tex]z=\frac{\sqrt{y-y^2}}y[/tex] to rewrite it again as
[tex]\displaystyle \int_0^{\pi/4} \sqrt{\tan(x) - \tan^2(x)} \, dx = 2 \int_0^\infty \frac{t^2}{(t^2+1)^2 + 1) (t^2 + 1)} \, dt[/tex]
where we take
[tex]\sqrt{y - y^2} = \sqrt{-y(y-1)} = yt \implies y = \dfrac1{1+t^2} \text{ and } dy = -\dfrac{2t}{(1+t^2)^2} \, dt[/tex]
Partial fractions:
[tex]\displaystyle \frac{t^2}{((t^2+1)^2+1) (t^2 + 1)} = \dfrac{t^2+2}{t^4+2t^2+2} - \dfrac1{t^2+1}[/tex]
so that
[tex]\displaystyle \int_0^{\pi/4} \sqrt{\tan(x) - \tan^2(x)} \, dx = 2 \left(\int_0^\infty \frac{t^2+2}{t^4+2t^2+2} \, dt - \int_0^\infty \frac{dt}{t^2+1}\right)[/tex]
The second integral is trivial,
[tex]\displaystyle \int_0^\infty \frac{dt}{t^2+1} = \lim_{t\to\infty}\tan^{-1}(t) - \tan^{-1}(0) = \frac\pi2[/tex]
For the other, I'm compelled to use the residue theorem, though real methods are doable too (e.g. trig substitution). Consider the contour integral
[tex]\displaystyle \int_\Gamma f(z) \, dz = \int_\Gamma \frac{z^2+2}{z^4+2z^2+2} \, dz[/tex]
where [tex]\Gamma[/tex] is a semicircle in the upper half of the complex plane, and its diameter lies on the real axis connecting [tex]-R[/tex] to [tex]R[/tex]. The value of this integral is 2πi times the sum of the residues in the upper half-plane. It's fairly straightforward to convince ourselves that the integral along the circular arc vanishes as [tex]R\to\infty[/tex], so the contour integral converges to the integral over the entire real line. Note that
[tex]\displaystyle 2 \int_0^\infty \frac{t^2+2}{t^4+2t^2+2} \, dt = \int_{-\infty}^\infty \frac{t^2+2}{t^4+2t^2+2} \, dt[/tex]
since the integrand is even.
Find the poles of [tex]f(z)[/tex].
[tex]z^4 + 2z^2 + 2 = 0 \\\\ ~~~~ \implies (z^2+1)^2 = -1 \\\\ ~~~~ \implies z^2 = -1 \pm i \\\\ ~~~~ \implies z = \pm \sqrt{-1 \pm i} = \sqrt[4]{2}\, e^{\pm i(3\pi/8 + \pi k)}[/tex]
where [tex]k\in\{0,1\}[/tex].
The two poles we care about are at [tex]z_1=\sqrt[4]{2}\,e^{i\,3\pi/8}[/tex] and [tex]z_2=\sqrt[4]{2}\,e^{-i\,11\pi/8}[/tex]. Compute the residues at each one.
[tex]\displaystyle \mathrm{Res}\left\{f(z),z=z_1\right\} = \lim_{z\to z_1} \frac{f(z)}{z-z_1} = -\frac1{2^{7/4}}\,ie^{-i\,\pi/8} \\\\ ~~~~~~~~~~~~~~~~~~~~~~~~= -\frac1{2^{7/4}} \left(\sin\left(\frac\pi8\right) + i \cos\left(\frac\pi8\right)\right)[/tex]
[tex]\displaystyle \mathrm{Res}\left\{f(z),z=z_2\right\} = \lim_{z\to z_2} \frac{f(z)}{z-z_2} = -\frac1{2^{7/4}}\,ie^{i\,\pi/8} \\\\ ~~~~~~~~~~~~~~~~~~~~~~~~= \frac1{2^{7/4}} \left(\sin\left(\frac\pi8\right) - i \cos\left(\frac\pi8\right)\right)[/tex]
By the residue theorem,
[tex]\displaystyle \int f(z) \, dz = 2\pi i \sum_{\rm poles} \mathrm{Res}\{f(z)\} = \frac{4\pi}{2^{7/4}} \cos\left(\frac\pi8\right)[/tex]
We also have
[tex]\displaystyle \cos^2\left(\dfrac\pi8\right) = \dfrac{1 + \cos\left(\frac\pi4\right)}2 = \dfrac{2 + \sqrt2}4 \implies \cos\left(\frac\pi8\right) = \dfrac{\sqrt{2+\sqrt2}}2[/tex]
Then the remaining integral is
[tex]\displaystyle \int_0^\infty \frac{t^2+2}{t^4+2t^2+2} \, dt = \frac{4\pi}{2^{7/4}} \cos\left(\frac\pi8\right) = \sqrt{\frac12 + \frac1{\sqrt2}} \, \pi[/tex]
It follows that
[tex]\displaystyle \int_0^{\pi/4} \sqrt{\tan(x) - \tan^2(x)} \, dx = \boxed{\left(\sqrt{\frac12 + \frac1{\sqrt2}} - 1\right) \pi}[/tex]

(r •q)(-3) =(q •r)(-3) = (2(-3)+2)((-3)² +1)
(r •q)(-3) =(q •r)(-3) = (-4)(9+1)
(r •q)(-3) =(q •r)(-3) = -4(10)

I know I'll have to work a double shift today because I have a migraine and every time I have a migraine I get stuck pulling a double. Is inductive or deductive
Deductive Reasoning.
What's the difference between inductive and deductive reasoning?
Inductive reasoning is a bottom-up approach, while deductive reasoning is top-down. Inductive reasoning takes you from the specific to the general, while in deductive reasoning, you make inferences by going from general premises to specific conclusions.
Examples-
Inductive Reasoning: The first lipstick I pulled from my bag is red. The second lipstick I pulled from my bag is red. Therefore, all the lipsticks in my bag are red.
Deductive Reasoning: The first lipstick I pulled from my bag is red.
A deductive approach involves the learners being given a general rule, which is then applied to specific language examples and honed through practice exercises. An inductive approach involves the learners detecting, or noticing, patterns and working out a 'rule' for themselves before they practise the language.
A deductive argument is said to be valid if and only if it takes a form that makes it impossible for the premises to be true and the conclusion nevertheless to be false. Otherwise, a deductive argument is said to be invalid.
Thus ,I know I'll have to work a double shift today because I have a migraine and every time I have a migraine I get stuck pulling a double is and example of Deductive reasoning . Because a deductive argument is said to be valid if and only if it takes a form that makes it impossible for the premises to be true and the conclusion nevertheless to be false.

Refer to the number line. Find the coordinate of point X such as the ratio of MX to XJ is 2:3
Please help it’s due soon
===========================================================
Explanation:
M is at 2 and J is at 18
This is a gap of 18-2 = 16
The ratio 2:3 has 2+3 = 5 parts total. Divide the gap of 16 into 5 equal parts to get 16/5 = 3.2 units
Each part is 3.2 units wide
Double this to get 2*3.2 = 6.4; the doubling is because of the "2" in "2:3"
Now add 6.4 to M = 2 to get 2+6.4 = 8.4 which is the location of point X
-----------------------
Check:
Segment MX is 8.4 - 2 = 6.4 units long
Segment XJ is 18-8.4 = 9.6 units long
The ratio 6.4:9.6 is the same as 64:96 and it fully reduces to 2:3 to confirm the answer. Or you could notice that (6.4)/(9.6) = 64/96 = 2/3

f(x) = x^2 + 4x is specified as a function. When the x is replaced in "f(x)" is replaced with a number, you treat it as a variable.
In this case, f(-3) is almost exactly like saying x = -3.
Everywhere x is in the function is replaced with -3, because you are plugging it in to find a value. Here is a demonstration:
f(-3) = (-3)^2 + 4(-3)
f(-3) = 9 - 12
f(-3) = -3
The answer to your question is -3. Don't be afraid to ask anymore questions regarding this if you are confused.
