The table represents a linear function. Which is the slope of the function?

Galina-37 [17]

From the table we have the points (-4, -2) and (-2, -10).

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

Substitute:

$m=\dfrac{-10-(-2)}{-2-(-4)}=\dfrac{-10+2}{-2+4}=\dfrac{-8}{2}=-4$

<h3>Answer: The slope = -4.</h3>

2. A square-based tent has the cross-sectional

ollegr [7]

(a) Length of the height is 2.732 m

(b) Length of the base is 5.466 m

<u>Explanation:</u>

An image is attached for reference.

(a)

In ΔAOB,

$sin 30^o = \frac{AO}{AB} \\\\0.5 = \frac{AO}{2} \\\\AO = 1 m$

In ΔBGD,

$sin 60^o = \frac{BG}{BD} \\\\0.866 = \frac{BG}{2} \\\\BG = 1.732 m$

According to the figure, BG = OE = 1.732 m

Height of the tent, AE = AO + OE

= 1 m + 1.732 m

= 2.732 m

(b)

DF = ?

In ΔAOB,

$tan 30^o = \frac{AO}{OB} \\\\0.577 = \frac{1}{OB} \\\\OB = 1.733 m\\\\\\$

According to the figure, OB = GE = 1.733 m

In ΔBGD,

$tan 60^o = \frac{BG}{DG} \\\\1.732 = \frac{1.732}{DG}\\ \\DG = 1m$

According to the figure, DE = DG + GE

DE = 1 m + 1.733 m

DE = 2.733 m

Length of the base, DF = 2 X DE

DF = 2 X 2.733 m

DF = 5.466 m

a briefcase selling for rs 1500 was marked down by 20% for a special promotion. it was later marked down further by 10% of the p

stiv31 [10]

Profit = 8%

If the briefcase was marked down 20% from 1500 you multiply 1500 x .2 = 300 in order to calculate the discount.

Calculate the discounted price:

1500 - 300 = 1200

Calculate 10% discount of 1200:

1200 x .1 = 120

Calculate the sales price:

1200 - 120 = 1080

The last step is to calculate the profit/loss is the cost is 1000.

The briefcase sold for 1080 and the company paid 1000 for it, so there was a profit of 80.

The percentage is calculate by dividing 80/1000 = 8% profit

What is the recursive formula for the sequence 3, -1, -5, -9, -13,...? a1 = 3, an = (an - 1)(-4) a1 = 3, an = (an - 1) – 4 a1 =

Thepotemich [5.8K]

Answer:

$a_{n}$ = $a_{n-1}$ - 4, $a_{1}$ = 3

Step-by-step explanation:

A recursive formula allows us to find the next term in the sequence from the previous term.

note the difference between the terms in the sequence

= - 13 - ( - 9) = - 9 - (- 5) = - 5 - (- 1) = - 1 - 3 = - 4

That is to obtain any term in the sequence we subtract 4 from the previous term, hence

$a_{n}$ = $a_{n-1}$ - 4, $a_{1}$ = 3
