for problem 6, you will want to subtract both sides by 5.

n^2 + 7n + 10 = 0

then factor:

(n + 5) (n + 2) = 0

n+ 5 = 0, n +2 = 0

n = -5, n = -2

----------------------------

for problem 7, add - 12 and - 6 together

n^2 + 3n - 18

(you can put = 0 next to the equation since that can make it easier to solve, I guess)

n^2 + 3n - 18 = 0

then factor:

(n + 6) (n - 3) = 0

n + 6 = 0, n - 3 = 0

n = -6, n = 3

The exponential model A=429e 0.024t describes the population, A, of a country in millions, t years after 2003. Use the model t

d1i1m1o1n [39]

Answer:

Year 2,590

Step-by-step explanation:

In this question, we are asked to calculate the year at which the population of a country will be a certain amount given the exponential equation through which the equation proceeds.

Let’s rewrite the exponential function;

A = 429e^0.024t

Now here, our A is 559,000,000

t is unknown

Let’s substitute this value of A in the exponential equation;

559,000,000 = 429 * e^0.024t

559,000,000/429 = e^0.024t

1,303,030.303030303 = e^0.024t

Let’s take the logarithm of both sides to base e, we have;

ln(1,303,030.303030303) = ln(e^0.024t)

14.08 = 0.024t

t = 14.08/0.024

t = 587 years

Now, we add this to year 2003 and this gives year 2590

If AB=AC then It is an isocoles triangle. Because of this, Angle ABC=ACB, meaning they are both 60°. This means that Angle BAC is also 60°. Becasue of circle theorms, the angle BOC=2BAC so angle BOC=120°

1. Find the value of the variable x. A) 7 √2/2 B) 7 √3/2 C) 14 √3 D) 14/3

Simora [160]

Answer:

$\frac{ \sqrt{7} }{2}$

Step-by-step explanation:

The triangle is an isosceles triangle. Because the triangle is an isosceles triangle, the height and base of the triangle are equal to eachother.

a² + b² = c²

right now we have c² which is 7

a² + b² = 7

$\frac{ \sqrt{7} }{2}$

because a² and b² are = to eachother

now im lost dony listen to me lol.
