Answer:

t = 1180 years

Step-by-step explanation:

We will solve this using the radioactive decay formula which is;

A = A_o × 2^(-t/h)

Where;

A = Amount of liquid remaining after time (t)

A_o = initial amount of liquid at initial time

t = time of decay

h = half-life of the liquid

We have;

A_o = 1(we assume it is 100% which is 1)

A = 0.02% = 0.0002

h = 96 years

Thus;

0.0002 = 1 × 2^(-t/96)

0.0002 = 2^(-t/96)

(-t/96)log 2 = log 0.0002

(-t/96) = (log 0.0002)/log 2

(-t/96) = -12.2877

t = 96 × 12.2877 (negative has canceled out)

t = 1179.6192

To the nearest year gives;

t = 1180 years

[tex]-3 + 2x[/tex]

Step-by-step explanation:

Given

[tex]2x - 3[/tex]

Required

An equivalent expression

The expression can be rewritten as:

[tex]-3 + 2x[/tex] ---- commutative property of addition

[tex]2x - 3[/tex] and [tex]-3 + 2x[/tex] are equivalent

An expression that has two terms that is equivalent to 2x – 3 is - 3 + 2x

Given:

2x - 3

There are just two terms in the expression

The two terms can be written interchangeably to form a new expression equivalent to the same

-3 + 2x (This is based on the cummutative property of addition)

The new expression equivalent to 2x - 3 is -3 + 2x (minus 3 plus 2x)

Answer:

In this problem, given the focus at (2,4) and directrix at y = 8. then it is implied that the parabola is facing downwards. The vertex hence is at the middle of the focus and the directrix, hence at (2, 6). The general formula of the parabola is y-k = -4a  ( x-h)^2. Substituting, y -6 = -1/8 *(x-2)^2. Answer is A.

Answer:

$162.05

Step-by-step explanation:

Calculation to determine How much do they spend weekly for food

Using this formula

Amount spent weekly=(Annual Disposable income*Disposable income percentage)/Numbers of weeks in a year

Let plug in the formula

Amount spent weekly=($44,350*19%)/52 weeks

Amount spent weekly=$8,426.5/52 weeks

Amount spent weekly=$162.048

Amount spent weekly=$162.05 (Approximately)

Therefore the amount they spent weekly for food is $162.05

so the total area is 113.04 and divide that in the total sections is 113.04 by 12 = C 9.42 in

Answer:

y=7/4x+2

Step-by-step explanation:

The linear equation in the slope-intercept form will be y = (7/4)x + 13/4.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The linear equation is given below.

y − 5 = 7/4(x − 1)

Convert the equation into a slope-intercept form. Then we have

y − 5 = 7/4(x − 1)

y − 5 = (7/4)x − (7/4)

y = (7/4)x − (7/4) + 5

y = (7/4)x + 13/4

The linear equation in the slope-intercept form will be y = (7/4)x + 13/4.

Answer:

3.4

Decrease ; 3.375

Step-by-step explanation:

Mean = Σfx / Σf

Σfx = (1 * 2) + (2 * 2) + (3 * 3) + (4 * 9) = 51

Σf = 1 + 2 + 3 + 9 = 15

Mean = 51 / 15 = 3.4

If 1 more dot is added to the 3rd column:

Σfx = (1 * 2) + (2 * 2) + (3 * 4) + (4 * 9) = 54

Σf = 1 + 2 + 4 + 9 = 16

Mean = 54 / 16 = 3.375

Answer:

i need points rq thanks so much

Step-by-step explanation:

imma go waste these points now

She'll have $246 more purchasing power.

Current salary per year = $41000

Next year salary = $41000 × (2.5% × $41000)

= $41000 + (0.025 × $41000)

= $41000 + $1025

= $42025

Effect of Inflation will be:

= $41000 + (1.9% × $41000)

= $41000 + (0.019 × $41000)

= $41000 + $779

= $41779

Therefore, the difference will be:

= $42025 - $41779

= $246
