Answer:
12+24÷(2^2+8)
Step-by-step explanation:
that should be the answer
if you struggle with questions that are like this use trial and error
C^2= a^2 + b^2 a=b
34^2= a^2 + a^2
1156=2a^2
a^2=1156/2
a^2=578
a=24.04
The side length is 24.04
Or I got this also
Using the special triangle theorem , an isosceles triangle has a diagonal equal to the square root of 2 of the legs of the triangle. In this case, the length of the legs is 34/ sqrt of 2 or equal to 24.04 units . This rule is based on the Pythagorean theorem
If the length of each side = x.
By Pythagoras' Theorem:
x² + x² = 34²
2x² = 34²
x² = 34² / 2
x² = 578
x = √578

Answer:
Step-by-step explanation:
“the center of the ellipse is located below the given co-vertex”
Co-vertex and center are vertically aligned, so the ellipse is horizontal.
Equation for horizontal ellipse:
(x-h)²/a² + (y-k)²/b² = 1
with
a² ≥ b²
center (h,k)
vertices (h±a, k)
co-vertices (h, k±b)
foci (h±c,k), c² = a² -b²
One co-vertex is (-8,9), so h = -8.
One focus is (4,4), so k = 4.
Center (h,k) = (-8,4)
c = distance between center and focus = |-8 - 4| = 12
b = |9-k| = 5
a² = c² + b² = 169
(x+8)²/169 + (y-4)²/25 = 1
864/8 gives you 108. There are 108 beads on each necklace. So for 15 necklaces, multiply 108 and 15. There are 1,620 beads in 15 necklaces.
