If the population of a town grew 21% up to 15,049. What is the population last year?

1 answer:

5 0

You can try formulating an equation to model this change:

Let 'x' be the population of the town last year. It follows that:
$1.21x = 15049 
$
and hence
$x = \frac{15049}{1.21}$

Answer:

The degree is 2

Step-by-step explanation:

2x³ and -2x³ cancel each other out, so the expression would be 4x²+x-32.

The largest exponent value is 2, as shown in "4x²"

HACTEHA [7]

Answer: y=2x+14

Explanation:
Y=mx+b
Y= 2x-4
M=2

Y= 2x+b

2 = (2 x -6) + b
2=-12+b
12+2=12+b
-12
14=0+b
14=b

Y=2x+14

let a,b,c,d be four integers (not necessarily distinct) in the set {1,2,3,4,5}. the no. of polynomials x^4+ax^3+bx^2+cx+d which

Eddi Din [679]

By either long or synthetic division, it's easy to show that

$\dfrac{x^4+ax^3+bx^2+cx+d}{x+1}=x^3+(a-1)x^2+(-a+b+1)x+(a-b+c-1)-\dfrac{a-b+c-d-1}{x+1}$

The quartic will be exactly divisible by $x+1$ when the numerator of the remainder term vanishes, or for those values of $a,b,c,d$ such that

$a-b+c-d-1=0$

I'm not sure how to count the number of solutions (software tells me it should be 80), but hopefully this is a helpful push in the right direction.

A triangular prism is 18 centimeters long and has a triangular face with a base of 12 centimeters and a height of 8 centimeters.

levacccp [35]

Answer:

672 sq cm

Step-by-step explanation:

Each triangular base is 1/2 (12 * 8) or 48, making them = 96.

One of the sides is 12 x 18 = 216

The other 2 sides are 10 x 18 = 180 x 2 = 360

Add them all together to get 672 sq cm
