Using row 4:
<span>coefficients are: 1, 4, 6, 4, 1 </span>
<span>a^4 + a^3b + a^2b^2 + ab^3 + b^4 </span>
<span>Now adding the coefficients: </span>
<span>1a^4 + 4a^3b + 6a^2b^2 + 4ab^3 + 1b^4 </span>
<span>Substitute a and b: </span>
<span>a = 4x </span>
<span>
b = -3y </span>
<span>1(4x)^4 + 4(4x)^3(-3y) + 6(4x)^2(-3y)^2 + 4(4x)(-3y)^3 + 1(-3y)^4 </span>
<span>Now simplify the above: </span>
<span>256x^4 - 768x^3y + 864x^2y^2 - 432xy^3 + 81y^4 </span>
Answer:
-3
Step-by-step explanation:
The graph shows the straight line.
To find the value at x = 2, draw the vertical line passing through the point (2,0). This line intersect the graph at some point. Draw the horizontal line through this point of intersection. This line intersects y-axis at point (0,-3). This means that the coordinates of the point lying on the graph are (2,-3) so
f(2) = -3
Answer:
39.5 degrees
Step-by-step explanation:
180-101=79
79/2=39.5
In most cases, the Card Act prevents credit card companies from raising the interest rate on an existing balance. In other words, if your rate goes up, the new rate will apply only to new charges going forward. But if you get hit with a penalty APR, your issuer is permitted to apply it to outstanding balances.
360/8 = 45.
