if there is figure add figure
Answer: C
<u>Step-by-step explanation:</u>
Varies inversely means xy = k
A. 1(-3) = -3
2(-9) = -18
-3 ≠ -18
B. 1(-6) = -6
2(-12) = -24
-6 ≠ -24
C. 1(6) = 6
2(3) = 6
3(2) = 6
6 = 6 = 6 This works!
D. 1(-3) = -3
2(2) = 4
-3 ≠ 4
The only table that has the same k-value is option C.
Answer:
perimeter of figure = 24.28
Step-by-step explanation:
semicircle ' s perimeter = π r = 3.14 × 2 = 6.28 cm
perimeter of 3 sides of parallelogram = 7 +7+4= 18 cm.
perimeter of figure = 18 +6.28 = 24.28
approx value = 24.30 cm
x² - 4x - 9 = 29
x² - 4x = 38
x² - 4x + (2)² = 38 + (2)²
(x - 2)² = 42
x - 2 = ±√42
x = √42 + 2 or x = -√42 + 2
x = 8.48 (nearest hundredth) or -4.48 (nearest hundredth)
