Answer:
y - 9 = -13(x - 1)
Step-by-step explanation:
sounds as tho you want to find the equation of a line thru the point (1, 9) that has a slope of -13. Use the point-slope formula y - k = m(x - h) for this purpose. Here m = -13, h = 1 and k = 9. Therefore,
y - k = m(x - h) becomes y - 9 = -13(x - 1). This is the desired equation in point-slope form.
The answer would be -325/8 but simplify that and u get -40 5/8 hope this helps
Answer:
C
Step-by-step explanation:
substitute -1 into all of the formulas, if both sides are equal, then it is correct, for C:
2(x-2)+6 = 0, sub -1
2(-1-2)+6=0, simplify and work out
2(-3)+6=0
-6+6=0
0=0
Answer:
2406.17 cm³
Step-by-step explanation:
The following data were obtained from the question:
Height (h) = 24.4 cm
Base length (L) = 17.2 cm
Volume (V) =?
Next, we shall determine the base area of the pyramid. This can be obtained as follow:
Base length (L) = 17.2 cm
Base area (B) =.?
B = L × L
B = 17.2 × 17.2
B = 295.84 cm²
Finally, we shall determine the volume of the pyramid. This can be obtained as follow:
Height (h) = 24.4 cm
Base area (B) = 295.84 cm²
Volume (V) =?
V = ⅓Bh
V = ⅓ × 295.84 × 24.4
V = 2406.17 cm³
Thus, we volume of the pyramid is 2406.17 cm³
