W x (w + 6) is the expression

To find area, we use the equation L×W=A

We need to fill in L and W with what we know.

A rectangle has a length that is 6 inches longer than its width. L=W+6; we need to use that equation for l

(w+6)w=A; let's simplify.

W²+6W=A

the number 1 is written on a piece of paper and then passed around the room to each of the 50 students in turn. each of the stud
Gnom [1K]

Answer:

The last term on the paper after 50 students = 2^{(50)} -1

Step-by-step explanation:

The general term of the equation:

Here, the first term = 1

Second term =  2(1) + 1  = 3  = 4 - 1  =  2^{2}  - 1

Third Term = 2(a2) + 1  = 2(3) + 1 = 7  = 8 -1 =   2^{3}  - 1

Fourth term = 2( a3) + 1 = 2(7) + 1 = 15  = 16 - 1  =  2^{3}  - 1

Continuing this way, we get

Last term : a_n = 2^n  -1

So, the 50th term of this sequence is

a_{(50)} = 2^{(50)} -1

Hence, the last term on the paper after 50th student changes it  = 2^{(50)} -1

Find the equation of the line with the coordinates of (-5,-2) and (5,3)​
velikii [3]

Answer

x - 2y = -1.

Step-by-step explanation:

Slope = (3 - (-2)) / (5 - (-5))

= 5/10

= 1/2

Using the point-slope form of a straight line equation:

y - y1 = m(x - x1)

Here m = 1/2 and (x1, y1) = (5, 3):

y - 3 = 1/2(x - 5)

y - 3 = 1/2x - 5/2

y = 1/2x  - 5/2 + 6/2

y = 1/2x +  1/2

Removing the fractions:

2y = x  + 1

in standard form this is

x - 2y = -1

Exponential and Logarithmic Functions HELP PLS
bulgar [2K]
1) c) y = 500 * 2^x 
In year 1, x = 1 and the population is 500 * 2^1 = 1000
In year 2, this doubles to 500 * 2^2 = 500 * 4 = 2000
ans so on
This model describes the population doubling every year

2) 
A) 3 (1/2)^x and C) (0.25)^x
These numbers reduce as x increases because there is a number with an absolute value less than 1 is being raised to the power of x. They also will never totally reach zero or become negative, but will approach zero as x becomes very large.

Kruka [31]

Answer:

x= -5 or -1

Step-by-step explanation:

subst y = -x + 5 into y = x^2 + 5x + 10

-x +5 = x^2 + 5x +10

x^2 +6x +5 = 0

(x+5)(x+1)=0

x= -5 or -1
