For which the value of f(x) = 2x^2 + 9 will be the same as g(x) = 3^x?
Answers
Answer:
For [tex]x = 3[/tex] the value of [tex]f(x) = 2\cdot x^{2}+9[/tex] will be the same of [tex]g(x) = 3^{x}[/tex].
Step-by-step explanation:
To determine for which value of [tex]x[/tex], we need to apply the following identity ([tex]f(x) = g(x)[/tex]) and solve numerically the resulting expression:
[tex]2\cdot x^{2}+9 = 3^{x}[/tex]
[tex]3^{x}-2\cdot x^{2}-9=0[/tex] (1)
A quick approach is using graphic tool and looking for the value of [tex]x[/tex] such that [tex]3^{x}-2\cdot x^{2}-9=0[/tex]. The result of the analysis is included below in the attached image. We find the following result:
[tex]x = 3[/tex]
For [tex]x = 3[/tex] the value of [tex]f(x) = 2\cdot x^{2}+9[/tex] will be the same of [tex]g(x) = 3^{x}[/tex].

You have 64 grams of a radioactive kind of strontium. If its half-life is 6 hours, how much will be left after 3 hours?
Answers
Answer: 48 grams
Step-by-step explanation:
The half-life of an element refers to the amount of time that it takes for half of it to decay.
For instance, if the half life is 2 hours and the element weighs 12 g, the element will only weigh 6g after 2 hours.
The half-life of the above is 6 hours, in 3 hours therefore, it would only have lost of the half that it would have lost in 3 hours which means it would have lost only a quarter.
= 64 * ( 1 - 1/4)
= 48 grams
Martha rolls a 6 sided number cube (number one through six) two times. What is the probability she will roll a 3 both times?
Answers
Answer:
2/12
Step-by-step explanation:
since there are six sides, rolling twice will give you a total of 12 possibilities, each time, you have 1 chance out of 6 each time to roll 3
1/6 + 1/6 = 2/12
If you want to, or need to reduce 2/12, divide both the numerator and denominator by two, and you will get 1/6 again.

B. x=6
Step-by-step explanation:
substitute -7 into 2y to get -14. your new equation should be 4x-14=10. add 14 to both sides to get 4x=24, divide both sides by 4 to get x=6.
Answer:
B. 6
Step-by-step explanation:
y = -7
4x + 2(-7) = 10
4x + (-14) = 10
4x = 10 - (-14)
4x = 24
x = 6
