Step-by-step explanation:
we know that'
The box displays the diagonal measurement of a tv.
so
Applying the Pythagoras Theorem
Let
d -----> the diagonal of TV
![d^{2}=W^2+L^2](https://tex.z-dn.net/?f=d%5E%7B2%7D%3DW%5E2%2BL%5E2)
substitute the given values
![d^{2}=34.2^2+60.8^{2}](https://tex.z-dn.net/?f=d%5E%7B2%7D%3D34.2%5E2%2B60.8%5E%7B2%7D)
![d^{2}=4,866.28](https://tex.z-dn.net/?f=d%5E%7B2%7D%3D4%2C866.28)
![d=69.8\ in](https://tex.z-dn.net/?f=d%3D69.8%5C%20in)
Round to the nearest whole number
![d=70\ in](https://tex.z-dn.net/?f=d%3D70%5C%20in)
Isosceles triangle always have exactly 1-fold refrectional symmetry.
Answer:
total cost of her loan be if she paid it off 8 years early $389,507.11
Step-by-step explanation:
The formula for annual compound interest, including principal sum P, rate of interest r, number of years t, and the number of times that interest is compounded per year is n:
A = P (1 + r/n)^ (nt)
<u>calculate total cost after 22 years</u>
P = $145,000
r = 4.5 %
t = 22 years
n = 12
A = P (1 + r/n)^ (nt)
A = 145,000(1 + 4.5/12)^ (22x12)
A = $389,507.11
Answer:
4.2
Step-by-step explanation:
By intersecting chords theorem:
![x \times 10 = 6 \times 7 \\ \\ 10x = 42 \\ \\ x = \frac{42}{10} \\ \\ x = 4.2](https://tex.z-dn.net/?f=x%20%5Ctimes%2010%20%3D%206%20%5Ctimes%207%20%5C%5C%20%20%5C%5C%2010x%20%3D%2042%20%5C%5C%20%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B42%7D%7B10%7D%20%20%5C%5C%20%20%20%5C%5C%20%20x%20%3D%204.2)
Answer:
Yes, y varies directly with x.
![y=\frac{11}{8} x](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B11%7D%7B8%7D%20x)
Step-by-step explanation:
![\frac{y}{x}=\frac{11}{8} =\frac{22}{16} =\frac{33}{24}](https://tex.z-dn.net/?f=%5Cfrac%7By%7D%7Bx%7D%3D%5Cfrac%7B11%7D%7B8%7D%20%3D%5Cfrac%7B22%7D%7B16%7D%20%3D%5Cfrac%7B33%7D%7B24%7D)
Hence
varies directly with
