It looks as though there are 25 21-40 year-olds. 40% of 25 is 10, this is the amount that are AGAINST the increase. Therefore the ones in favor for the increase must be 25 - 10 = 15.

You should be able to follow the same process to get the 41-60 year-olds against an increase. Just be sure to read the given information carefully

Given an initial quantity Q0=150 and a growth rate of 7% per unit time, give a formula for the quantity Q as a function of time

rodikova [14]

Answer:

Step-by-step explanation:

From the given information:

(a)

Since growth quantity is not continuous

$Q(t) = 150 (1.07)^t$

For t = 10

$Q(10) = 150 (1.07)^{10}$

$\mathbf{Q(10) = 295.073}$

(b)

Here, for a continuous growth rate, the growth quantity can be computed in terms of initial quantity and the growth rate.

i.e.

$Q(t) = 150 e^{0.07t}$

At t = 10 for a continuous growth rate;

$Q(10) = 150 e^{0.07 \times 10}$

$Q(10) = 150 e^{0.7}$

$\mathbf{Q(10) = 302.063}$

1) 2x – y = 1

aleksandrvk [35]

Answer:

1) (2, 3)

2) (2, -5).

Step-by-step explanation:

2x – y = 1

2x +2y = 10 Subtract to eliminate the 2x:

2x - 2x - y - 2y = 1 - 10

-3y = -9

y = 3.

Plug this into the first equation:

2x - 3 = 1

2x = 4

x = 2.

2)

5x – y =15

x + y = -3 Adding to eliminate y:

5x + x - y + y = 15 + -3

6x = 12

x = 2

Plug this into the first equation:

5(2) - y = 15

-y = 15 - 10 = 5

y = -5.
