Step-by-step explanation:
for 1 they give us an angle and the side next to that angle.. or the Adjacent side and they want to know the Opposite side from the angle sooo let's use ..
SOH CAH TOA
hmm TOA seems good , it's got the adj and Opp in it ,
Tan(Ф) = Opp / Adj
Tan(67) = Opp / 26
26 * Tan(67) = Opp
61.2521 = Opp
61.3 ( rounded to nearest 10th ) does this seem big to you? well it should be quite a bit bigger than the 25 on the base, seems about right to me
for 2 they give us one angle, 48 , and one side, 35 , that is opposite from that angle, and ask what is the Hyp. So find a trig function that has those pieces in it. SOH seems good
sin(Ф) = Opp / Hyp
sin(48) = 35 / Hyp
Hyp = 35 / sin(48)
Hyp = 47.0971 ( and that seems about right for the Hypotenuse )
x = 47.1 ( rounded to the nearest 10th )
for 3 they are asking us to imagine a triangle, I'll draw it and attach it as a picture. Looking at the picture helps a lot, we can see we have the angle and the adj side and want to find the Opposite side of that big triangle. sooo use TOA , it's got those pieces in it
Tan(17) = Opp / 200
200*Tan(17) = Opp
61.1461 =Opp
so the height of the radio mast is 61.1 meters ( rounded to nearest 10th )
Does this seem a bit easier when you think about how the parts of the trig functions fit on the triangles? :) ask if you have any questions

Which of the following ordered pairs satisfy the function y = -3x + 4? Select all that apply.
Answers
Answer:
A and C
Step-by-step explanation:
To determine which of the following satisfies the function y = -3x + 4, plug in the values of (x, y) of each options given into the equation.
Option A: (x, y) = (4, -8)
-8 = -3(4) + 4
-8 = -12 + 4
-8 = -8 (true)
Therefore, (4, -8) satisfies the function given.
Option B: (x, y) = (2, -10)
-10 = -3(2) + 4
-10 = -6 + 4
-10 = -2 (not true)
Therefore, (2, -10) DOES NOT satisfies the function given.
Option C: (x, y) = (-1, 7)
7 = -3(-1) + 4
7 = 3 + 4
7 = 7 (true)
Therefore, (-1, 7) satisfies the function given.
Option D: (x, y) = (-3, 4)
4 = -3(-3) + 4
4 = 9 + 4
4 = 13 (NOT true)
Therefore, (-3, 4) DOES NOT satisfies the function given.

one integer is 6 more than another. their product is 216. find the integers.
Answers
Answer:
-18 and -12
Or, 18 and 12
Step-by-step explanation:
Let the integers be 'a' & 'a + 6'.
Their product = 216
=> a x (a + 6) = 216
=> a² + 6a = 216
=> a² + 6a - 216 = 0
=> a² + (18 - 12)a - 216 = 0
=> a² + 18a - 12a - 216 = 0
=> a(a + 18) - 12(a + 18) = 0
=> (a + 18)(a - 12) = 0
=> a = - 18 or a = 12
Integers are: -18 and -18+6 = -12
Or, 12 and 12 + 6 = 18
An occupational safety officer for a large company is conducting a study to investigate back problems in office workers who use a computer for most of the workday. The study will

is randomly assigned to work while standing, and the other half is assigned to work while sitting. At the end of the study, the mean number of back problems between the two
groups will be calculated. The officer will use the results to estimate the difference in the mean number of back problems between those who work while standing and those who
work while sitting

E) A two sample t-interval for difference between population means.
When to use the t-distribution and the z-distribution?If we have the standard deviation for the sample, the t-distribution is used.If we have the standard deviation for the population, the z-distribution is used.In this problem, we will have the data from the sample, hence it is a t-test. We will compare the population means of the two groups, hence a two-sample t-interval is used, and option E is correct.

A passenger jet can fly 1290 miles in three hours with a tail wind but only 1230 miles in three hours into a Herman. Find the speed of the jet in still air and the speed of the wind
Answers
The speed of the plane is 420 miles per hour and the speed of the wind is 10 miles per hour.
Answer:
I only know English, so that's perfect :P
Step-by-step explanation:
I'm going to guess... that "Herman" is really "headwind" and that this jet is flying into ( headwind) and with ( tailwind) the same wind... so the same velocity wind ( note I used the physics term velocity for the speed of the wind b/c the wind also has to have a direction... and we are saying it's direction and it's speed are constant)
so take the difference of the two distances... 1290 - 1230 = 60
we now know... that the difference in distance traveled is 60 miles, so 1/2 of that is what's gained or lost , by a tailwind or a headwind, so 30 miles is gained or last flying into the wind or with the wind.
also this is in 3 hours , how convenient, 30 / 3 = 10
the wind is 10 MPH
there fore.... the jet could fly 1260 miles in 3 hours with out any wind or
d = rt where d= distance , r= rate ( think speed) and t = time ( of course [ofc] )
1260 = r * 3 hours
420 = r
the jets speed is 420 MPH

Some steps are shown in converting the following conic inequality from general form to standard form. Complete the conversion and identify the shape, key feature, and which ordered pair is part of the solution set.
Answers
Answer:
hyperbola with a solid line boundary
(4, -2)
(0, -4)
Step-by-step explanation:
Took one for the team Edge 2021
The shape of the given equation is hyperbola with solid line boundary, key feature i.e. the center is at (4, -2), and ordered pair is (0, -4) and the standard form will be [tex]\frac{(x-4)^2}{9} -\frac{(y+2)^2}{4} \leq1[/tex] .
What is conic section ?Conic section is a curve obtained by the intersection of the surface of a cone with a plane.
we have,
[tex]4x^2-32x-9y^2-36y-8\leq 0[/tex]
And,
The general form of a Conic Section is,
[tex]Ax^2+Bxy+Cy^2+Dx+Ey+F=0[/tex]
And,
The Standard form of a is,
[tex]\frac{(x-h)^2}{a^2} +\frac{(y-k)^2}{b^2} =1[/tex]
So,
Now,
[tex]4x^2-32x-9y^2-36y-8\leq 0[/tex]
Then,
[tex]4x^2-32x-9y^2-36y\leq8[/tex]
Now, taking common,
[tex]4(x^2-8x)-9(y^2+4y)\leq8[/tex]
Now,
Adding 64 and subtracting 36 to both sides ,
We get,
[tex]4(x^2-8x+16)-9(y^2+4y+4)\leq8+64-36[/tex]
Now,
factor the perfect square,
i.e.
[tex]x^2-8x+16=(x-4)^2[/tex]
Now,
[tex]y^2+4y+4=(y+2)^2[/tex]
Now,
[tex]4(x-4)^2-9(y+2)^2\leq36[/tex]
Now,
Divide both sides by 36,
i.e.
[tex]\frac{4(x-4)^2}{36} -\frac{9(y+2)^2}{36} \leq\frac{36}{36}[/tex]
We get,
[tex]\frac{(x-4)^2}{9} -\frac{(y+2)^2}{4} \leq1[/tex]
So, this is the standard form of the given cubic inequality.
Hence, we can say that the shape of the given equation is hyperbola with solid line boundary, key feature i.e. the center is at (4, -2), and ordered pair is (0, -4) and the standard form will be [tex]\frac{(x-4)^2}{9} -\frac{(y+2)^2}{4} \leq1[/tex] .
