Answer:
5. 4√2 N
6. 20 N
Step-by-step explanation:
We're not sure how your diagram relates to the notion of the weight being "pushed". Usually T represents "tension," which would indicate a "pull" in up and to the right.
__
5. The side ratios in this triangle match exactly those in your problem 1. T is √2 times the equal side lengths, so is T = 4√2 N.
__
6. The sides ratios in the triangle match exactly those in your problem 2. T is 2 times the shorter side length, so is T = 20 N.

What is the midpoint of (-7,-9) (6,3)
Answer :
Let the first term of both the terms be [tex]\: \sf \: x _1 \: \: \& \: \: x _2[/tex] and last term be [tex]\: \sf \: y _1 \: \: \& \: \: y_2\\ [/tex]
Now, by using the mid point formula to find the mid point of the segment -
[tex] \\ \sf \bigg( \frac{x_1 + x_2}{2} , \: \frac{y_1 + y_2}{2} \bigg) \\ [/tex]
Now, by substituting the values of both x and y -
[tex] \\ \sf \bigg( \frac{ - 7 + 6}{2} , \: \frac{ - 9 + 3}{2} \bigg) \\ [/tex]
Adding -7 and 6 -
[tex] \\ \sf \bigg( \frac{ - 1}{2} , \frac{ - 9 + 3}{2} \bigg) \\ [/tex]
Now, move the negative in front of the fraction -
[tex] \\ \sf \bigg( \frac{ - 1}{2} , \frac{ - 6}{2} \bigg) \\ \\ \\ \sf \bigg( \frac{ - 1}{2} , - 3\bigg) \\ [/tex]
6 boxes weigh the same amount. If the boxes weigh 60 pounds all together, how many pounds does each box weigh. (hElp)
Answer:
Each would equal 10 lbs.
Step-by-step explanation:
60 pounds all together is the weight of 6 boxes, so if you divide 60 by 6, you'll get 10 lbs for each box.
Answer:
each box weighs 10lbs
Step by Step explanation:
if you do 10 20 30 40 50 60 70.... you will see what times what gives you 60 which in this case it is what times 6 gives you 60 so if you list your 6s you will will go until you get to 6*10 which is 60 but you can do a list of your 10s it is easier that away to be honest. I hope this answer helps you:)

create a rule or identity to describe those patterns. For example, if you notice that every time you multiply a negative number by another negative number the result is positive, we can generalize this by saying (-a)(-b) = c, where a, b, and c are all positive real numbers.
Answer:
a/b = a * 1/b
Step-by-step explanation:
a/b = a * 1/b
this looks easy....
But what about
a / (1/b) = a*b
if you see any division, you can always multiply BOTH the numerator AND the denominator by the same amount. That is allowed because that is the same as multiiplying by the number 1.
So multiply by b/b and see what happens.
a / (1/b) = b/b * a / (1/b)
group the numerator AND the denominator
a / (1/b) = (b * a ) / b*(1/b)
a / (1/b) = (b * a ) / b/b
a / (1/b) = (b * a ) / 1
a / (1/b) = (b * a )
a / (1/b) = a*b
It is allowed because you can always multiply any number by 1 and that is because that will not change the original number. The number multiplied by 1 remains the same number.
This notion is very powerful and it can be used to turn any division into a multiplycation, and vice versa.
a / (1/b) = a*b
Answer:
This equation generalizes the patterns seen in part D, where a and b represent real numbers:
(a + bi)(a − bi) = a2 + b2.

What is the equation in standard that passes through the point (5,6) and has a slope of 3?
Answer: y=3x-9
Step-by-step explanation: To solve this, you'd first have to substitute 5,6 into an equation (you know that slope in standard form is y=mx+b, where m is slope and b is figure 0, or the y intercept), you have an x and a y. Then solve.
y=mx+b (y=6, m=3, and x=5)
6=3(5)+b --- Substitute values
6=15+b --- Subtract 15 from both sides (solving for b)
6-15=-9
b=-9
Hope this helps; let me know if you need further elaboration, as this is kind of hard to grasp at first.
Sincerely,

Choose all the expressions that are equal to 4.19 + 6.53.
A. 4.2 + 6.5
B. 16.75 – 6.03
C. 1.72 + 9
D. 15 – 4.38
E. 6.53 + 4.19
Answer:
16.75-6.03
1.72+9
6.53+4.19
Step-by-step explanation:
4.19 + 6.53 = 10.72
The expressions that is equal to 10.72 can be calculated as follows
4.2 +6.5 = 10.7
16.75-6.03 = 10.72
1.72 + 9= 10.72
15-4.38= 10.62
6.53 + 4.19= 10.72
Hence the expressions which is equal to 10.72 are
16.75-6.03 , 1.72+9 , 6.53+4.19

Miss kito made a large donation to protect a rare species of mosquito that environmentalist declared endangered, thanks o miss kito's generosity, the insects were transplanted to a protected area. the population P (in thousands) of the insects in t months after being transported is: p(t)=50(1+0.05t)/2+0.01t...what is the limiting factor on the insect population as time progresses?
Answer:
Step-by-step explanation:
Given the population of insects in t months after being transported to be p(t)=50(1+0.05t)/2+0.01t., to get the insect population as time progresses, we will substitute t = infinity into the equation
p(infty) = 50(1+0.05(infty))/2+0.01(infty)
P(infty) = 50(1+infty)/infty
P(infty) = infty/infty (Ind)
Apply l'hopital rule
P'(t) = 50(0.05)+0/0.01
P'(t) = 2.5/0.01
P'(t) = 250
Hence the limiting factor on the insect population as time progresses is 250 populations
The factors that affect the population of the rare species of the mosquito are what are referred to as the limiting factors.
There are several limiting factors that affect population growth of the mosquitoes; some of them are:
FoodWaterSpaceCompetition with other mosquitoesAs time progresses, the amount of mosquitoes may or may not increase.
If the population size of the mosquito increases, then the limiting factors are favorable.If otherwise, the population size decreases or remains constant with time, then the limiting factors are not favorable.This in other words means that, a limiting factor is anything that slows down or stops the population size of the mosquitoes

How do I find the missing side
Answer:
x = 11.8639
Step-by-step explanation:
cos∅ = adjacent / hypotenuse
Since we are dealing with right triangles, we can use trig to help solve for missing values:
cos22° = 11/x
xcos22° = 11
x = 11/cos22°
x = 11.8639
Solve: x³-7x²+36=0.
Answer:
3,6,-2
Step-by-step explanation:
a+2a+b = 7
2a^2b = -36
a*2a + ab + 2ab = 0
or, a(2a+3b) = 0
so, b = -2a/3
Solve those and you find 3,6,-2

Step-by-step explanation:
pls help me. this is inverse trigonometric function
I'll do the first problem to get you started.
In place of [tex]\sin^{-1}[/tex] I'll use arcsine
So [tex]\sin^{-1}(x) = \arcsin(x)[/tex]
-------------------------------------------------
Using that hint given, we can get the following
cos(arcsin(3x) - pi)
cos(arcsin(3x))*cos(pi) + sin(arcsin(3x))*sin(pi)
cos(arcsin(3x))*(-1) + sin(arcsin(3x))*(0)
-cos(arcsin(3x)) + 0
-cos(arcsin(3x))
Now the question is how to evaluate the cosine of an inverse trig function, especially when it's not inverse cosine.
The trick (often with many trig and geometry problems) is to draw out a triangle. Specifically we'll need a right triangle.
Check out the diagram below. I've drawn out a right triangle with reference angle theta, opposite leg of length 3x, and hypotenuse 1.
Note how sin(theta) = opposite/hypotenuse = 3x/1 = 3x
We can then go from sin(theta) = 3x to theta = arcsin(3x)
This ultimately means
cos(arcsin(3x)) = cos(theta)
cos(arcsin(3x)) = adjacent/hypotenuse
cos(arcsin(3x)) = sqrt(1-9x^2)/1
cos(arcsin(3x)) = sqrt(1-9x^2)
The sqrt(1-9x^2) is the result of using the pythagorean theorem.
---------------------------
So that means the final answer is [tex]-\sqrt{1-9x^2}[/tex]

Please only answer if you actually know how to). Some methods for graphing equations work well with certain equations and some don't. Help Asap). Knowing which method to select based on the given equation is a valuable skill. You have learned three methods to graph equations. These methods are: • y = mx+ b, • find intercepts, • use a t-chart. A) Using the following 3 equations, answer the questions: 11x + y =4, x+y = -2, x - 2y = 18. 1) How can you determine which equations can be graphed more easily using x - and y -intercepts, rewriting in slope-intercept form, or using a table of values? 2) Which method works best for you personally? When does it not work as well?
Answer:
please dont blame me if i get this wrong this is what i put.
Step-by-step explanation:
Using the following 3 equations, answer the questions:
11x + y =4, x+y = -2, x - 2y = 18
How can you determine which equations can be graphed more easily using x- and y-intercepts, rewriting in slope-intercept form, or using a table of values?
you can determin which is eiser to graph by wether or not they have numbers infront of the x and y intercepts. i find it mutch eiser if they allready have the numbers there. its also eiser to graph 11x + y =4 and x - 2y =18 on a slope intercept rather than table of values because you allready can find the points for those two eiser than the last one which would be used on the table of values. for the problem x+y=-2 you would use x and y intercepts. for 11x+y=4, rewriting in slope form is the corect method to use. and finaly use the table of values method for x-2y=18.
Which method works best for you personally? When does it not work as well?
the one that i find works best for me personally is probably gonna be the slope intercept method as apposed to many other methods. it doesnt work all the time because nothing can but normaly when i have a problem with this method i can just go to the table of values method and get the answer. (sorry if this is wrong this is what im putting for my answer. dont copy and paste this though if u do desiede to use it, read it and turn it into your own words so its not obvious you found the answer on the internet. and tbh i didnt read the lesson i just am ok at comming up with answers useing the question and getting away with it. )
