Answer:
6.5km
Step-by-step explanation:
If you make a diagram, you'll see the submarine forms a right angle triangle with the base, where the hypotenuse is the length from the submarine to its base, and 5.5 and 3.4 are the side lengths. To find the hypotenuse, use the formula a^2+b^2=c^2.
5.5^2+3.4^=c^2
41.81=c^2
6.466=c
Round it to one decimal point and you get 6.5km.
Answer:
y = -x + 8
Step-by-step explanation:
x-3y = -18
-3y = -x -18
3y = x + 18
m = 1 ( but Product of slope of perpendicular lines is -1 so, M= -1)
y-intercept from (4,4) is
4 = -1 (4 )+ b
b= 8
The equation of the line that passes through the given point (4,4) is
y =mx +b
y = -1 x + 8
Use the formula A=Asub0(1+/-intrest)^time for compounded annually. In this case it would be A=500(1+.03)^6. Hope this helps!
Answer:
x = 9
Step-by-step explanation:
for any two intersecting chords, the product of their section lengths will be identical.
20(2x + 3) = 14(3x + 3)
40x + 60 = 42x = 42
18 = 2x
x = 9
To start, you can use clue 2 because there is only one variable in it.
Solve for the value of the circle, by dividing both sides by 3.
Then you can plug that value into clue 1 to solve for the diamond.
Once you find the value for the diamond, you can plug both values, the diamond and the circle, into clue 3, to solve for the triangle.
