Answer:
у = x² + 7x - 30
Step-by-step explanation:
x₁ = 3 and x₂ = -10
Use the formula (x - x₁)(x - x₂) = 0
(x - 3)(x - (-10)) = 0
(x - 3)(x + 10) = 0
x² + 10x - 3x - 30 = 0
x² + 7x - 30 = 0
The answer is 3
The question is wrong tho its not the same as the picture
Its not
16x + 181 = 12x
Its
6x +18= 12x
And the solution is
-18 on bothes sides then we have left 6x=12x-18
Then we take -12x on both sides
6x-12x= -18 6x-12x = -6x
-6x=-18
The u divede -18 = -6x
———
-6 -6
Then u get -18/-6= 3 and -6x/-6 = x
x = 3
I feel like it would be 5/12, but im not 100% sure
Answer:
Effective annual yield = 0.05094534 or 5.094%
Step-by-step explanation:
Given:
Rate of interest (r) = 5% = 0.05
Interest = compounded quarterly
Find:
Effective annual yield = Y
Computation:
![Y=(1+\frac{r}{n} )^n-1\\\\Y=(1+\frac{0.05}{4} )^4-1\\\\Y=(1+0.0125 )^4-1\\\\Y=(1.0125 )^4-1\\\\ Y=1.05094534-1\\\\Y=0.05094534\\\\\\](https://tex.z-dn.net/?f=Y%3D%281%2B%5Cfrac%7Br%7D%7Bn%7D%20%29%5En-1%5C%5C%5C%5CY%3D%281%2B%5Cfrac%7B0.05%7D%7B4%7D%20%29%5E4-1%5C%5C%5C%5CY%3D%281%2B0.0125%20%29%5E4-1%5C%5C%5C%5CY%3D%281.0125%20%29%5E4-1%5C%5C%5C%5C%20Y%3D1.05094534-1%5C%5C%5C%5CY%3D0.05094534%5C%5C%5C%5C%5C%5C)
Effective annual yield = 0.05094534 or 5.094%
If you give 4 points your friend has -2 points and you have 1 point you would be winning but if you take 4 than your friend has -10 points and you have -7 points so either way you win
