Answer:
a. 7
b. 2
Step-by-step explanation:
a. By the secant secant theorem, 5 ( x+5) = 6 (4+6)
5x + 5 = 60
5x = 35
x =7
b. 4(x+4) = 3 (3 + 5)
4x + 16 = 24
4x = 8
x = 2
Hope it helps and if it does please make me BRAINLIEST
x
Answer:
(- 4, - 2 )
Step-by-step explanation:
Under a rotation about the origin of 90°
a point (x, y ) → (- y, x ) , then
(- 2, 4 ) → (- 4, - 2 )
About 2983 ft as you find the circumfrence and mult by 5
Here is your system of equations:
200x + 400y = 3200
y = 2x
Now plug into your calculator to see the graph.
Where the lines cross each other is the point that shows the solution.
Answer:
Step-by-step explanation:
The formula for this is
where
N is the amount of the element left after a certain amount of time (for us it is measured in days),
N₀ is the initial amount of the element in grams,
t is the number of days gone by, and
H is the half life of the element. Filling in:
which simplifies a bit to
and a bit more to
N = 42(.25) which gives us a remaining amount of
N = 10.5
