Answer:
I think the answer is 9ft squared is the perimeter on each side of the kite.
Step-by-step explanation:
Answer:
Step-by-step explanation:
tan28=h/150
h=150tan28
h=79.8ft
x/(12+8)=5/8
x/20=5/8
x=100/8
x=12.5
A cube has 6 sides. Divide the surface area by 6 to get the area of one side:
13 1/2 /6 = 2 1/4
The area of one side is S^2
To fins the length of the sides find the square root of the area:
Side = sqrt(2 1/4)
Side = 1 1/2 cm.
Answer:
Therefore the value of a is 3.78.
Step-by-step explanation:
Indices Rule:
Given that,
(a,b) satisfies the two equations
.........(1)
and
.........(2)
From equation (1) we get
![ab^4=384](https://tex.z-dn.net/?f=ab%5E4%3D384)
Squaring both sides
![\Rightarrow (ab^4)^2=(384)^2](https://tex.z-dn.net/?f=%5CRightarrow%20%28ab%5E4%29%5E2%3D%28384%29%5E2)
......(3)
Divide equation (3) by (2) we get
![\frac{a^2b^8}{a^2b^5}=\frac{147,456}{4608}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%5E2b%5E8%7D%7Ba%5E2b%5E5%7D%3D%5Cfrac%7B147%2C456%7D%7B4608%7D)
![\Rightarrow a^{2-2}b^{8-5}=32](https://tex.z-dn.net/?f=%5CRightarrow%20a%5E%7B2-2%7Db%5E%7B8-5%7D%3D32)
![\Rightarrow b^3=32](https://tex.z-dn.net/?f=%5CRightarrow%20b%5E3%3D32)
![\Rightarrow b=\sqrt[3] {32}](https://tex.z-dn.net/?f=%5CRightarrow%20b%3D%5Csqrt%5B3%5D%20%7B32%7D)
Now plug the value of b in equation (1)
![ab^4=384](https://tex.z-dn.net/?f=ab%5E4%3D384)
![\Rightarrow a(\sqrt[3]{32})^4=384](https://tex.z-dn.net/?f=%5CRightarrow%20a%28%5Csqrt%5B3%5D%7B32%7D%29%5E4%3D384)
![\Rightarrow a(32)^\frac43=384](https://tex.z-dn.net/?f=%5CRightarrow%20a%2832%29%5E%5Cfrac43%3D384)
![\Rightarrow a=\frac{384}{(32)^\frac43}](https://tex.z-dn.net/?f=%5CRightarrow%20a%3D%5Cfrac%7B384%7D%7B%2832%29%5E%5Cfrac43%7D)
![\Rightarrow a\approx 3.78](https://tex.z-dn.net/?f=%5CRightarrow%20a%5Capprox%203.78)
Therefore the value of a is 3.78.
