Basically, all you have to do is substitue the terms given at the top.

x = -3

y = 6

z = -4

The first one will be set up like this:

(-3) + 6 + (-1) = 2

The second one will be set up like this:

-15 + (- -3) + 6 = -6

The third one will be set up like this:

3(-3) - 2(6) + (-4) = -25

The fourth one will be set up like this:

2(-4) - 3 (6) + 4(-3) = -38

The fifth one will be set up like this:

3 ( -3) + 2 (6) + (-4) = -1

The sixth will be set up like this:

(-3)(-4)

---------- = -1

-2 (6)

The seventh will be set up like this:

2 (6) (-4) - 3 (-3) = -39

Hope this helps! Have a good day/night! c:

Valeria drives 500 meters up a hill that makes an angle of 15 degrees with the horizontal. To the nearest tenth of a meter, what

s344n2d4d5 [400]

Answer:

Approximately 485 meters

Step-by-step explanation:

We can first construct a right triangle, using the 500 m length of hill as our hypotenuse. Using the fact that the cosine of an angle is the ratio of the adjacent side to the hypotenuse, we see that

$\cos{15^\circ}=\frac{x}{500}$

where x is the horizontal distance covered. Solving for x, we find this horizontal distance to be

$x=500\cos{15^\circ}\approx500(0.97)=485$

so our answer is approximately 485 m.

Which point do all exponential functions of the form y=a^x pass through

Bezzdna [24]

The answer should be A.

When we see the equation y=a^x we can relate to all the exponential functions, however, when the problem asked what points does all equations in that form pass through. I was instantly reminded by two facts.

One is that any number to the first is equal to itself. In other words, a^1=a

Another is that any number to the zero is equal to 1. a^x=1
if that is true, 1 will always be the x value since y=a^x and 0 will always be the x value because that is how y can be equal to one.
therefore, the answer is A: (0,1)

To approach the runway, a pilot of a small plane must begin a 10 degrees descent starting from a height of 1983 feet above the g

ddd [48]

<h3>Answer:</h3>

2.2 miles

<h3>Explanation:</h3>

The mnemonic SOH CAH TOA reminds you that

... Sin = Opposite/Hypotenuse

We are given an angle (10°) and its opposite side length (1983 ft), and we are asked to find the hypotenuse (the straight-line distance from the plane to the runway).

... sin(10°) = (1983 ft)/distance

Multiplying by distance and dividing by sin(10°), we have ...

... distance = (1983 ft)/sin(10°) ≈ 11419.6 ft

We want to express this in miles, so we have ...

... 11419.6 ft = (m mi)×(5280 ft/mi)

... (11419.6 ft)/(5280 ft/mi) = m mi ≈ 2.163 mi

Rounding to tenths, the distance is ...

2.2 miles

Comment on the question

The distance from the plane to the airport is different than the horizontal distance from the airport at which the descent must start. The latter distance is the "adjacent" leg of the triangle, so must be found using the tangent function. Rounded to tenths, it is 2.1 miles.

Find the locus of the point (x,y) which is a distance 3 from the point (-2, 1)

Reptile [31]

Consider this option:
1. rule: Circle is the locus of the points which are on the same distance from the given point. Common view of the equation is: (x-a)²+(y-b)²=r², where r - the distance from the given point to the described locus, a&b - coordinates of the given point.
2. using item 1:
(x+2)²+(y-1)²=3² or (x+2)²+(y-1)²=9.

Find the unknown size please I really need answers

katen-ka-za [31]

Answer:

z=80°(corresponding angles)

 $x+z=180°(linear \: pair \: ) \\ 80° + x = 180° \\ x= 100°$ 

y=100 ° (alternate angles)
