Answer:
12.87
Step-by-step explanation:
Find the difference between 50 and 37.13
50 - 37.13 = 12.87
Hope this helped
Your points are (-2, 7) and (18, 1). To find the slope, use the slope formula (y_2 - y_1)/(x_2 - x_1)
(18, 1) --> (x_2, y_2)
(-2, 7) --> (x_1, y_1)
(1 - 7)/(18 - (-2)) --> -6/20 --> -3/10
The slope of the line passing through the points (-2, 7) and (18, 1) is -3/10.
Answer:
No
Step-by-step explanation:
If (x - 9) is a factor then x = 9 is a root and f(9) = 0
f(x) = 4x³ - 28x² - 36x - 27, hence
f(9) = 4(9)³ - 28(9)² - 36(9) - 27
= 2916 - 2268 - 324 - 27 = 297
Since f(9) ≠ 0 then (x - 9) is not a factor of f(x)
Answer:
Her mistake was not multiplying both sides of the equation by 0.5
Step-by-step explanation:
The mistake is in Step 1--Tiffany was correct in multiplying the left side (h / 0.5) by 0.5 but made an error on the right side by dividing the 7 by 0.5 instead of multiplying.
<em>Thus, h= 3.5</em>
To find the area of the square multiply the length by the height.
12.4 × 12.4 = 153.76
