Answer:
60.04 cm
Step-by-step explanation:
Let the sides of the equilateral triangle be
The equilateral triangle has a height of 52 cm.
From the diagram in the attachment, we can apply the Pythagoras Theorem to obtain:
This implies that:
We multiply through by 4 to get:
Group similar terms to get:
Take square root to get:
Let me show u one in detail.
First we have to find the common ratio. We do this by dividing the second term by the first term.
ur first problem...
12/3 = 4...so the common ratio is 4
now we use the formula
an = a1 * r^(n-1)
n = term u want to find = 15
a1 = first term = 3
r = common ratio = 4
now we sub
a15 = 3 * 4^(15 - 1)
a15 = 3 * 4^14
a15 = 3 * 268435456
a15 = 805,306,368 <== ur 15th term
thats all there is to it...and, of course, u can always look on the internet for a geometric sequence calculator...to check urself...lol
Answer:
- y1 = -x +5
- y2 = 2x +14
- (x, y) = (-3, 8)
Step-by-step explanation:
We notice that x=0 is halfway between x = -1 and x = 1, so the corresponding y-intercepts will be ...
for y1, (6+4)/2 = 5
for y2, (12+16)/2 = 14
Each step in x is +2. The steps in y1 are -2, so the slope is -2/2 = -1.
The steps in y2 are +4, so the slope is 4/2 = 2.
Now, we have the slopes and intercepts, so we can write the system of equations as ...
y1 = -x +5
y2 = 2x +14
__
The y-values are shown as equal in the table for x=-3, so the solution of the system of equations is ...
(x, y) = (-3, 8)
