Answer:

∠1 - 40°

Step-by-step explanation:

∠1 - 40°

b/c it's a right triangle and we have two angles given, 50° and 90°. Add them and subtract by 180° and get 40°.

∠2 - 140°

b/c an exterior (outside) angle is equal to the two most isolated / farthest angles added. The two most is angles are 105° and 35°, add them and get 140°.

∠3 - 40°

b/c ∠'s 1 and 3 are vertical angles meaning they're equal so since ∠1 is 40°, so is ∠3.

∠4 -

b/c ∠' s 2 and 4 are vertical angles meaning they're equal so since ∠2 is 140°, so is ∠4.

∠5 - 35°

b/c we have two angles, 105° and 40°. Add them and subtract by 180° and get 35°.

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 $d=3$

Suppose you deposit $12.50 into your savings account each week for 4 weeks and then withdraw $4.80 each week for the next two we

monitta

Answer:

The total change in the amount of money in my account is $ 9.60

Step-by-step explanation:

Given:

Amount of money deposited each week, $A_{d}=\$12.50$

Amount of money withdrawn each week, $A_{w}=\$4.80$

∴ Amount of money deposited in 4 weeks, $A_{dT}=A_{d}\times 4=12.50\times 4 = \$50$

∴ Amount of money withdrawn in 2 weeks, $A_{wT}=A_{w}\times 4=4.80\times 2 = \$9.6$

Now, amount of money left in the account is the difference of the two amounts.

So, amount left = $A_{dT}-A_{wT}=50-9.6=\$40.4$

Therefore, the total change in the amount of money in my account is given as:

Total change = Initial amount after 4 weeks - Final amount in the account.

Total change = $ 50 - $40.4 = $ 9.6
