Answer:
Step-by-step explanation:
.95
I don't know what the easiest way to do this is. I just divide 19 by 2 and shift the decimal around. That doesn't sound very helpful.
The answer should be nearly one. It should be less than one, but not by much.
So divide 19 by 2 and you get 9.5 but you know that the answer is less than one, so shift it one more place to the left.
Answer:
x = 10
Step-by-step explanation:
Given the 2 equations
12x - 6y = 60
24x + 6y = 300
Adding the 2 equations term by term will eliminate the y- term, that is
36x + 0 = 360
36x = 360 ( divide both sides by 36 )
x = 10
Answer: 3.82 miles
Step-by-step explanation:
According to the shown figure, we can imagine the scene as a <u>right triangle</u>, where the tower is located at the right angle, and the fireman and the forest fire located at each of the other two vertices.
So, since we are dealing with a right triangle we can use the Pithagorean Theorem, in order to find the distance from the fireman to the fire
, which is also the hypotenuse.
![d^{2}= (2.1 miles)^{2} +(3.2 miles)^{2}](https://tex.z-dn.net/?f=d%5E%7B2%7D%3D%20%282.1%20miles%29%5E%7B2%7D%20%2B%283.2%20miles%29%5E%7B2%7D)
![d=\sqrt{(2.1 miles)^{2} +(3.2 miles)^{2}}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%282.1%20miles%29%5E%7B2%7D%20%2B%283.2%20miles%29%5E%7B2%7D%7D)
Finally:
![d=3.82 miles](https://tex.z-dn.net/?f=d%3D3.82%20miles)
1. None are correct it would be either 1/3, 2/6, 3/9, 4/12, 5/15
2.B
3.C
4.C
Answer:
Option D.
Step-by-step explanation:
From the given graph it is clear that it is a parabola along to the x-axis.
Vertex form of a parabola along the x-axis is
where, (h,k) is vertex.
From the graph it is clear that the vertex of the parabola is (4,-3). So, substitute h=4 and k=-3 in the above equation.
...(1)
The graph passing through (1,-2), so substitute x=1 and y=-2 in the above equation.
Substitute a=-3 in equation (1).
Therefore, the correct option is D.
