Use the graph below to determine a1 and d for the sequence. graphed sequence showing point 1, negative 10, point 2, negative 7,

Sonja [21]

Answer:

$a_1=-10$

$d=3$

Step-by-step explanation:

we know that

In an <u><em>Arithmetic Sequence</em></u> the difference between one term and the next is a constant, and this constant is called the common difference (d)

In this problem we have the ordered pairs

$(1,-10),(2,-7),(3,-4),(4,-1),(5,2),(6,5)$

Let

$a_1=-10\\a_2=-7\\a_3=-4\\a_4=-1\\a_5=2\\a_6=5$

Find the difference between one term and the next

$a_2-a_1=-7-(-10)=3$

$a_3-a_2=-4-(-7)=3$

$a_4-a_3=-1-(-4)=3$

$a_5-a_4=2-(-1)=3$

$a_6-a_5=5-2=3$

The difference between one term and the next is a constant

This constant is the common difference

so

The sequence graphed is an Arithmetic Sequence

therefore

The first term is $a_1=-10$

The common difference is equal to $d=3$

"This summer, the water level of Lake Conroe changed by a rate of -1.5 feet per month. The water level at the beginning of May w

Verdich [7]

Answer:

181 feets

Step-by-step explanation:

Given that:

Rate of change in water level = - 1.5 feets per month

Water level at beginning of May = 187 feets above sea level

Water level at the end of 4 months =?

Total change after four months = rate of change per month * number of months

= - 1.5 * 4 = - 6 feets

Hence water level after 4 months :

187 feets + (-6 feets)

187 feets - 6 feets

= 181 feets

Help me , this is my homework (Geometry) . I really need help

klemol [59]

8. Similar parts

$\dfrac{6}{18} = \dfrac{AQ}{12}$

$AQ = 12(6)/18=12/3=4$

Choice a

9. The Law of Sines says a:b:c and $\sin A : \sin B \sin C$ are the same ratio.

The sines will go in order for acute angles, we have to convert 120 to its supplement 60 and then the order is 29,31,"60" or opposite sides JK, KL, JL

choice b

10.

DEF and FEG are supplments, FEG=180-DEF=180-114=66

DEF and HEG are opposite angles, so congruent HEG=DEF=114

Allen is buying a video that originally cost $49.He has a 10%-off coupon and will have to pay a 6% sales which expression will c

Gekata [30.6K]

Answer:

$46.746

Step-by-step explanation:

Allen is buying a video that originally cost = $ 49

Discount coupon = 10%

Sales tax= 6%

Hence, the price of video after discount coupon and sales tax= $ 49 × $\frac{100-10}{100}$ × $\frac{100+6}{100}$

Hence, the price of video after discount coupon and sales tax= $ 49 × $\frac{90}{100}$ × $\frac{106}{100}$

Price of video after discount coupon and sales tax= $ 49 × 0.9× 1.06

price of video after discount coupon and sales tax= $46.746

Hence, the correct answer is $46.746
