The population of town increases by5℅ every year. In the last year, the population was 80,000. 1) find the present population 2)

Readme [11.4K]

Answer:

last year it was 80k

Step-by-step explanation:

Population increases by 5% every year

Last year it was 80,000

PRESENT POPULATION

Present population = 80,000 + 5% off 80,000

= 80,000 + 5/100 × 80,000

= 80,000 + 5 × 800

= 80,000 + 4,000

= 84,000

AFTER ONE YEAR

After this , the population again increases by 5%

Population = 84,000 + 5% off 84,000

= 84,000 + 5/100 × 84,000

= 84,000 + 5 × 840

= 84,000 + 4,200

= 88,200

ANSWERS

The population of present year is 84,000

After one year , the population becomes 88,200

Hope it helps :-)

Given f(x)=2x3+x−8 verify that f(x) is invertible and, if so, find the equation of the tangent line to f−1(x) at the point where

Nitella [24]

The derivative, f'(x) = 6x^2+1, is never negative, so f(x) is monotonic, hence invertible.

f'(-2) = 6(-2)²+1 = 25

If point (-2, -26) is on the graph of function f(x), and the slope is 25 there, then (-26, -2) is on the graph of f⁻¹(x), and the slope is 1/25 there. The equation of the tangent line throught that point can be written in point-slope form as

... y +2 = (1/25)(x +26)

Jason bought 6 movie tickets and four bags of popcorn Michael bought two movie tickets and three bags of popcorn each bag of pop

svlad2 [7]

Answer:

Equation is $8M + 7P = 131$

$M = \$12$

Step-by-step explanation:

Given

Jason: 6 Movies and 4 popcorn

Michael: 2 Movies and 3 Popcorn

1 Popcorn = $5

Total = $131

Required

- Write an equation to solve

<em>Represent Movie with M and Popcorn with P</em>

For Jason, we have:

6M + 4P

For Michael, we have:

2M + 3P

Add these parameters together

Jason + Michael = $131

$6M + 4P + 2M + 3P = 131$

Collect Like Terms

$6M + 2M+ 4P + 3P = 131$

$8M + 7P = 131$

Hence the equation is $8M + 7P = 131$

From the question, we have that

$P = \$5$

Substitute 5 for P

$8M + 7 * 5 = 131$

$8M + 35 = 131$

Solve for M

$8M = 131 -35$

$8M = 96$

$M = \frac{96}{8}$

$M = \$12$
