Gekata [30.6K]

Answer:

A. A(n) = 150 • (0.74)^n–1 ; 33.29 cm

Step-by-step explanation:

This is a geometric sequence.

a%5B1%5D=1.5m=150cm, r=0.74

The formula is

a%5Bn%5D=a%5B1%5Dr%5E%28n-1%29

Just substitute a1 = 150cm and r = 0.74

a%5Bn%5D=150%280.74%29%5E%28n-1%29

That's the rule.

For the second part, substitute n = 6

cm.

find the point, M, that divides segment AB into a ratio of 5:2 if A is at (1,2) and B is at (8, 16).

Paha777 [63]

Answer:

Step-by-step explanation:

A(1,2) ---->(x1,y1)

B(8,16) ----->(x2,y2)

m:n = 5:2

$M(\frac{x_{2}m+x_{1}}{m+n},y_{2}m+y_{1}}{m+n})\\\\=M(\frac{5*8+2*1}{5+2},\frac{5*16+2*2}{5+2})\\\\=M(\frac{40+2}{7},\frac{80+4}{7})\\\\=M(\frac{42}{7}{,\frac{84}{7})\\\\=M(6,12)$

What values of x make the equation x(squared)+9x-22=0

kkurt [141]

Answer:

$x = 2 \: \: \: \: \: or \: \: \: \: \: x = - 11$

Step-by-step explanation:

${x}^{2} + 9x - 22 = 0 \\ {x}^{2} + 11x - 2x - 22 = 0 \\ x(x + 11) - 2(x + 11) = 0 \\ (x - 2)(x + 11) = 0 \\ x - 2 = 0 \: \: \: \: \: or \: \: \: \: \: x + 11 = 0 \\ x = 2 \: \: \: \: \: or \: \: \: \: \: x = - 11$
