What is the exact value of the other root?
The exact value of the other root to the quadratic equation is [tex]x = -2 - \sqrt 6[/tex]
How to express the solution?One of the root is given as:
[tex]x = -2 - \sqrt 6[/tex]
As a general rule, the solution to a quadratic equation is represented by:
[tex]x =\frac{-b \pm \sqrt{b^2 -4ac}}{2a}[/tex]
This means that the actual root of the given root is:
[tex]x = -2 \pm \sqrt 6[/tex]
Split the equation
[tex]x = -2 - \sqrt 6[/tex] and [tex]x = -2 + \sqrt 6[/tex]
Hence, the exact value of the other root to the quadratic equation is [tex]x = -2 - \sqrt 6[/tex]

If Jacob lives until the end of the term of his policy, the total amount he would have paid in premiums overall is $50,850.
How much would he have paid in premiums?
Total premium payment = (face value / average premium rate) x number of years x premium
($500,000 / 1000) x $6.78 x 15 = $50,850

Answer:

Step-by-step explanation:
Suppose you write the numbers 1 to 10 on separate index cards. You randomly choose one card, place it back in the set, and then randomly choose another card. What is the probability that the first card you choose is the number 1 or the second card you choose is the number 2?.
Answer:
1/100
Step-by-step explanation:
From 1 to 10 there are 10 numbers, so the fraction would be:
# / 10
Since you are putting the cards back into the deck, the denominator will never change.
The chances of getting " 1 " are 1 / 10.
And the chances of getting " 2 " are also 1 / 10
To find the odds of getting one-after-the-other, you multiply these 2 chances.
( 1 / 10 ) x ( 1 / 10 ) = ( 1 / 100 )
There is a 1 / 100 chance that you will draw 1, then 2 if you put the cards back after drawing.

1. When drawn in standard position, which of the following angles is coterminal with 125?
(1) -275
(3) 235
(2) 485
(4) 415
The angle which is coterminal with the angle 125 degree when drawn in standard position is -235 degrees. Option A is correct.
What is the coterminal or terminal side of an angle?The terminal side of an angle is the rotated side of the initial side around a point to form an angle. This rotation can be clockwise or counter clock wise.
The angle given in the problem is,
θ=125°
The angle which is coterminal of this angle is,
θ=125°-360°
θ=-235°
Thus, the angle which is coterminal with the angle 125 degree when drawn in standard position is -235 degrees. Option A is correct.

Write the sequences equation for the table . Your equation should be in the form a(n)=man+b
Answer:
a(n) = 3.25n + 1.25Step-by-step explanation:
7.75-4,5 = 3.25
11-7.75 = 3.25
14.25-11 =3.25
17.5-14,25 = 3.25
It’s clear that this is an arithmetic sequence with common difference of 3.25
The equation form of such sequence is a(n) = a×n + b ,where ‘a’ is the common difference.
Then
a = 3.25
The first term a₁ = 4.5
On the other hand, a₁ = 3.25 ×(1) + b
Then
4.5 = 3.25 ×(1) + b
Then
b = 4.5 - 3.25 = 1.25
Conclusion:
a(n) = 3.25n + 1.25

A quantity with an initial value of 870 decays continuously at a rate of 0.75% per day.
what is the value of the quantity after 10 weeks, to the nearest hundredth?
The function of the exponential decay will be y = 870(0.75)ˣ. Then the value of the quantity after 10 weeks will be 49.
What is exponential growth or decay function?Consider the function:
y = a(1 ± r)ˣ
where x is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.
If there is a plus sign, then there is exponential growth happening by r fraction.
If there is a negative sign, then there is exponential decay happening by r fraction.
A quantity with an initial value of 870 decays continuously at a rate of 0.75% per day.
Then the function is given as
y = 870(0.75)ˣ
Then the value of the quantity after 10 weeks will be
y = 870(0.75)¹⁰
y = 870 (0.0563)
y = 48.99
