Answer:
solving equation by quadratic formula method, we get:
D = b² - 4ac
=(-5)² - 4 × 1 × 3
=25-12=13
D> 0,
so it has real roots.
x=- b ± √D/2a
- 5 ± √13/2
Correct choice [A] and [C].

show all work. what is the measure in degrees of angle A?
Answers
Answer:
∠ A = 62°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
116° is an exterior angle of the triangle, then
3x - 13 + 2x + 4 = 116
5x - 9 = 116 ( add 9 to both sides )
5x = 125 ( divide both sides by 5 )
x = 25
Then
∠ A = 3x - 13 = 3(25) - 13 = 75 - 13 = 62°

A game decreased in price by 1/4
After the reduction it was priced at £27.
What was the original price of the game
Answers
Answer:
£36.
Step-by-step explanation:
Because the game was reduced by 1/4
This means that:
£27 = 3/4.
To find 1/3, divide 27 by 3. this gives us 9. Now we know that the game was reduced by £9. To find the original price, instead of taking £9 away, we do the inverse and add the £9. This gives us £36.
You can even check your answer also, as 9 is 1/4 of 36, this proving that the price before the reductio was £36.

Step-by-step explanation:
4x times 4x will give you 16x^2, and 9 times 9 is 81, but you need to have one of the nines negative to give you the -81.
You needed the square root of 16 and the square root of x^2, then the square root of 81.
The giant panda population in China is increasing at a rate of 1.5% each year. There are 1864 giant panda in 2014. Write a function that models the panda population since 2014.
(exponential growth & decay)
Answers
Given:
Giant panda population in 2014 = 1864
The giant panda population in China is increasing at a rate of 1.5% each year.
To find:
The function that models the panda population since 2014.
Solution:
Since population of giant panda is increasing, therefore the function is the exponential growth model.
The general exponential growth model is:
[tex]P(t)=P_0(1+r)^t[/tex]
Where, [tex]P_0[/tex] is the initial population, r is the growth rate in decimal and t is the time period.
Putting [tex]P_0=1864,r=0.015[/tex], we get
[tex]P(t)=1864(1+0.015)^t[/tex]
[tex]P(t)=1864(1.015)^t[/tex]
Where, t is the number of years since 2014.
Therefore, the required exponential growth model is [tex]P(t)=1864(1.015)^t[/tex].
