Answer:
C & F
Step-by-step explanation:
29 - 13 is 16 and 46 - 21 is 25. Everything else is wrong because the differences are not the correct answers except for C and F. Sorry if this sounds kinda confusing
This is probably wrong so...
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.
(x + 3) is a factor so x = -3 must be a root.
a.
This is the geometric sequence: a1 = 1.5 m = 150
cm, r = 0.74
The formula now is an = a1 x r ^ n-1
Just substitute a1 = 150 cm and r = 0.74
an = 150 x (0.74) ^ n – 1
b.
The second part is:
A6 = 150 x 0.74 ^ 6-1
= 150 x 0.74 ^5
= 150 x 0.221906624
= 33.28509936 cm
Assuming the numbers are percents, the answer is 25%, because 5/20 is 1/4, then convert the fraction to a percentage and you get 25%.
