If x+y= -4 and xy=2, then find the value of x²+y²​

Answer:

[tex]P(Y|X)=\frac{P(Y\cap X)}{P(Y)} \\ P(Y\cap X) = P(Y)P(Y|X) \\ = 0.45 \times 0.25 \\ \boxed{P(Y\cap X) =0.1125} \\ P(Y\cup X) = P(Y) + P( X) - P(Y\cap X) \\ = 0.45 + 0.35 - 0.1125 \\ \boxed{P(Y\cup X) =0.6875}[/tex]

Answer:

<MQP = 138 degrees

Step-by-step explanation:

5x + 19 = 2x + 49

5x - 2x = 49 - 19

3x = 30

x = 30/3

x = 10

2 (<MQN) = 5(10) + 19 = 69 * 2 = 138 degrees

First term: 3

Exiplicit formula:

[tex]3/5*5^n[/tex] or 3x5^n-1

Hope this helps!

The first term is 3 and the explicit rule for the given geometric sequence is 3 × [tex]5^{n-1}[/tex].

A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.

For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.

As per the given GP series,

3,15,75,375, 1,875​

The common ratio r = 15/3 = 5

First term a = 3

The nth term is given as a[tex]r^{n-1}[/tex]

Therefore,

The nth term will be as, 3 × [tex]5^{n-1}[/tex]..

Hence "The first term is 3 and the explicit rule for the given geometric sequence is 3 × [tex]5^{n-1}[/tex]".

Answer:

we get $812.95:  total cost

Step-by-step explanation:

The sales tax on this $750.99 camera is found as follows:  0.0825($750.99) = $61.96.  Adding this amount to the $750.99 price, we get $812.95:  total cost.

A faster way to calculate the total cost is to multiply $750.99 by (1.0825):  again we get $812.95

Answer:

Discount: $10.60  Price: $42.40

Step-by-step explanation:

Since 20% just means 1/5, you can divide the original price by 5 to find the discount and then just subtract the discount from the original price to find the discounted price.

because with the rate of change it makes a straight line

Step-by-step explanation:

s = 3 and t = 2

= 2(8 + t)³ - 6

= 2(8 + 2)³ - 6

= 2(10)³ - 6

= 2(1.000) - 6

= 2.000 - 6
