Answer:

(a) an = -4·2^(n-1)

Step-by-step explanation:

The form for the general term is ...

an = a1·r^(n-1) . . . . . a1 is the first term; r is the common ratio

For a1=-4 and r=-8/-4 = 2, the rule will be ...

an = -4·2^(n-1)

melomori [17]

Answer:

Ratio of sweaters to dresses = 8 : 5

Sum of ratios = 13

Let number of sweater + dresses = x

$number \ of \ sweaters = \frac{8}{13} *x\\\\24 = \frac{8}{13}*x\\\\x = \frac{24*13}{8} = 3*13 = 39$

$number \ of \ dresses = 39 - 24 = 15$

Craig has £13.40

strojnjashka [21]

Yes
Step-by-step explanation:
Full price for first course: £8.90
Half price: £4.45
One and one half times
full price is then: £13.35
Since this is less than Craig's £13.40, he can just barely afford to buy two main courses at these prices.

write the equation of the line perpendicular to the line through the points (5, -4) and (1,4) and passes through the point (0,4)

LUCKY_DIMON [66]

Answer:

y = 1/2x + 4

Step-by-step explanation:

Line through the points:

(5, -4) and (1, 4)

Equation of line

y = mx + b
m = (4 -(-4))/(1 - 5) = 8/(-4) = -2
y = -2x + b

Perpendicular line has a slope that is negative reciprocal to this one, so

y = 1/2x + b

This line has y-intercept of 4 as it passes through the point (0, 4)

So the line is:

y = 1/2x + 4
