Paladinen [302]

Answer:

Step-by-step explanation:

$2x^2+16x-8=0$

Simplify:

$x^2+8x=4$

Rewrite in the form $(x+a)^2=b$ :

$x^2+8x=4$

Add $4^2$ to both sides:

$x^2+8x+4^2=4+4^2$

$x^2+8x+4^2=20$

$\left(x+4\right)^2=20$

$x+4=\sqrt{20}$ or $x+4=-\sqrt{20}$

x = -4± $\sqrt{20}$

x= -4± $2\sqrt{5}$

The initial population of a town is 2500, and it grows with a doubling time of 10 years. What will the population be in 8 years?

alisha [4.7K]

2500x0.80=2000 so i think it would be 2000 in 8 years

or if youre adding the 2000 to the already existing 2500 then it would be 4500.

A 9-yard roll of string costs $3.42. What is the unit price?

Karolina [17]

Answer:

$0.38 per yard

Step-by-step explanation:

Step 1:

Given; A 9-yard roll of string that costs $3.42.

Required; To find the unit price

Step 2:

Convert $3.42 to cents

$1 ~dollar=100~cents ~\\therefore,\\$3.42=3.42~x~100=342~cents~$

Step 3:

Find the unit price

$\frac{9 yard}{1 yard} =\frac{342 ~cents}{x~cents}$

$9x=342$

$\frac{9x}{9} =\frac{342}{9}$

$x=38~cents$

Convert to dollars

$x=\frac{38}{100}$

$x=0.38~per~yard$

Hence the unit price is $0.38 per yard.

Find the distance between the two points rounding to the nearest tenth (if necessary).

Genrish500 [490]

Answer:

13 units

Step-by-step explanation:

(-1,5) and (4, -7)

To find the distance of two points, we use the distance formula:

$d = \sqrt{(x_{2}-x_1)^2 + (y_2-y_1)^2 }$

Let's plug in what we know.

$d = \sqrt{(4 - (-1))^2 + (-7 - 5)^2 }$

Evaluate the double negative.

$d = \sqrt{(4 +1))^2 + (-7 - 5)^2 }$

Evaluate the parentheses.

$d = \sqrt{(5)^2 + (-12)^2 }$

Evaluate the exponents.

$d = \sqrt{(25) + (144) }$

Add.

$d = \sqrt{(169) }$

Evaluate the square root.

$d = 13$

13 units

Hope this helps!
