Answer:
D) -10
Step-by-step explanation:
We will assign g(x) to be equal to 25, and then solve for x:
25 = -3x-5
30 = -3x
10 = -x
-10 = x
So D is correct
Answer:
-10 is correct option
Step-by-step explanation:
g(x)=-3(x)-5
g(-10)=-3(-10)-5
=30-5
=25

After a while, Jada picks up a coin that seems different than the others. She notices that the next day, only half of the coin is left!
On the second day, only 1/4 of the coin is left.
On the third day, 1/8 of the coin remains.
What fraction of the coin remains after 6 days?
What fraction of the coin remains after 28 days? Write an expression to describe this without computing its value.
Does the coin disappear completely? If so, after how many days?
Answers
Answer:
After 6 days 1/64 of the coin will remain, while after 28 days 1/268435456 will remain. Now, it will never completely disappear, since it can always be reduced to a larger number.
Step-by-step explanation:
Since after a while, Jada picks up a coin that seems different than the others, and she notices that the next day, only half of the coin is left, while on the second day, only 1/4 of the coin is left and, on the third day, 1/8 of the coin remains, to determine what fraction of the coin remains after 6 days, what fraction of the coin remains after 28 days and determine if the coin will disappear completely, the following calculation must be performed:
1/2 ^ 6 = X
0.015625 = X
1/64 = X
1/2 ^ 28 = X
0.0000000037252902984619140625 = X
1/268435456 = X
Thus, after 6 days 1/64 of the coin will remain, while after 28 days 1/268435456 will remain. Now, it will never completely disappear, since it can always be reduced to a larger number.

4. 2x2 + 4x + 10 = 0
Answers
Answer:
Step-by-step explanation:
This doesn't factor. Not only that, but it does not give real results. The discriminate is negative.
a = 2
b = 4
c = 10
You could divide this equation by 2
a = 1
b = 2
c = 5
These three are smaller and easier to calculate. The answer will be the same.
x = (- b +/- sqrt(b^2 - 4*a*c ) / (2 a)
x = (-2 +/- sqrt(^2 - 4(1)*(5) ) / 2*1
x = (-2 +/- sqrt(4 - 20) ) / 2
X = (-2 +/- sqrt(-16) ) /2
x = (-2 +/- 4i ) / 2
x = ( - 1) +/- 2i

Do the functions have the same concavity? f(x)=-x^2+40x+120f(x)=−x 2 +40x+120
Answers
Answer:
1. f(x)=-x^2+40x+120. Answer: it would be the same answer
2. f(x)=−x 2 +40x+120. Answer: look at the both picture
Step-by-step explanation: Hope this help :D
Both functions have the same concavity—they are both concave downward.
How to explain the functionLet's start with the first function, f(x) = -x² + 40x + 120.
First Derivative:
f'(x) = -2x + 40
Second Derivative:
f''(x) = -2
Since the second derivative is a constant (-2), it is negative for all values of x. Therefore, the first function has a concave downward shape.
Now let's move on to the second function, f(x) = -x² + 40x + 120.
First Derivative:
f'(x) = -2x + 40
Second Derivative:
f''(x) = -2
Similar to the first function, the second function also has a constant second derivative (-2) that is negative for all values of x. Therefore, the second function also has a concave downward shape.
In conclusion, both functions have the same concavity—they are both concave downward.

The population of China was about 1.39 billion in the year 2013with an annual growth rate of about 0.6\% . Find an equation P(t) that represents the growth function for China. Write your answer in the form a * (b) ^ 2 in billions Provide your answer below:
Answers
Answer: 1.39(1.006)^t
Step-by-step explanation:
The equation P(t) that represents the growth function for China is P(t) = 1.39 * ( 1.006)ⁿ.
What is a Function ?A statement that relates two unknown parameters such that one is dependent on the other is called a function.
It is given that
Initial population = 1.39 billion in 2013
Growth Rate = 0.6%
Let a represent the initial population
b is the growth rate
and 2 be the elapsed year from 2013
and let the population at any given year is P(t)
Then the equation formed is
P(t) = a * bⁿ
P(t) = 1.39 * ( 1.006)ⁿ
Therefore the equation P(t) that represents the growth function for China is P(t) = 1.39 * ( 1.006)ⁿ.

Can you please show work thank you for your time
Answers
Answer:
x= 20,1 degrees
Step-by-step explanation:
The sum of the inner angles of a triangle is 180 degrees
So it must be
3x-11+6x-10+x = 180
added up the terms with x
10x -11-10 = 180
added up the terms without x
10x - 21 = 180
added up (21) in the two members of the equation
10x-21+21 = 180+21
10x = 201
divide the two members by 10
x = 20,1 degrees
