Answer:
f(n) = 74 + 11(n - 1)
<u>For the 7th term</u>
n = 7
f(7) = 74 + 11(7 - 1)
= 74 + 11(6)
= 74 + 66
<h2>= 140</h2>
<u>For</u><u> </u><u>the</u><u> </u><u>8</u><u>t</u><u>h</u><u> </u><u>ter</u><u>m</u>
n = 8
f(8) = 74 + 11( 8 - 1)
= 74 + 11(7)
= 74 + 77
<h2 /><h2>= 151</h2>
Hope this helps you
Answer:
Option A.
Step-by-step explanation:
we have
![x+\frac{b}{2a} =\pm\sqrt{\frac{b^2-4ac}{4a^2}}](https://tex.z-dn.net/?f=x%2B%5Cfrac%7Bb%7D%7B2a%7D%20%3D%5Cpm%5Csqrt%7B%5Cfrac%7Bb%5E2-4ac%7D%7B4a%5E2%7D%7D)
Simplify the right side of the equation
we know that
![\pm\sqrt{\frac{b^2-4ac}{4a^2}}=\pm\frac{\sqrt{b^2-4ac}}{\sqrt{4a^2}}=\pm\frac{\sqrt{b^2-4ac}}{2a}](https://tex.z-dn.net/?f=%5Cpm%5Csqrt%7B%5Cfrac%7Bb%5E2-4ac%7D%7B4a%5E2%7D%7D%3D%5Cpm%5Cfrac%7B%5Csqrt%7Bb%5E2-4ac%7D%7D%7B%5Csqrt%7B4a%5E2%7D%7D%3D%5Cpm%5Cfrac%7B%5Csqrt%7Bb%5E2-4ac%7D%7D%7B2a%7D)
so
The expression is
![x+\frac{b}{2a}=\pm\frac{\sqrt{b^2-4ac}}{2a}](https://tex.z-dn.net/?f=x%2B%5Cfrac%7Bb%7D%7B2a%7D%3D%5Cpm%5Cfrac%7B%5Csqrt%7Bb%5E2-4ac%7D%7D%7B2a%7D)
therefore
x plus b over 2 times a equals plus or minus the square root of b squared minus 4 times a times c, all over 2 times a
2x-6=2x-16+10
2x-2x=10+6-16
0=0
the maximum weight the person can be is 245lbs
Answer:
90
Step-by-step explanation:
60/100=x/150
180/300=2x/300
2x=180
x=90
