Which equation represents an exponential function with an initial value of 500? O f(x) = 100(5) f(x) = 100(x) Rx) = 500(2) f(x) = 500(x)2
Answers
Answer: C
Step-by-step explanation:
The equation represents an exponential function with an initial value of 500 is, [tex]\rm f(x) = 500(2)^x[/tex].
We have to determine, which equation represents an exponential function with an initial value of 500?
According to the question,
An exponential function formula can be defined by,
[tex]\rm f(x) = ab^x[/tex]
Where the input variable is denoted as x occurs as an exponent.
And b is the growth value or decay constant.
The exponential curve depends on the exponential function and it depends on the value of the x.
Therefore,
The equation represents an exponential function with an initial value of 500,
[tex]\rm f(x) = 500(2)^x[/tex]
Where the input variable is denoted as x occurs as an exponent.
And b is 2 the growth value or decay constant.
Hence, The required equation represents an exponential function with an initial value of 500 is, [tex]\rm f(x) = 500(2)^x[/tex].

Binomial(−4x−6) and trinomial(−3x2+5x+6) are the factors of what polynomial? Question
Answers
Answer:
12x³ - 8x² - 54x - 36
Step-by-step explanation:
The polynomial is the product of the factors, that is
(- 4x - 6)(- 3x² + 5x + 6)
Each term in the second factor is multiplied by each term in the first factor, that is
- 4x(- 3x² + 5x + 6) - 6(- 3x² + 5x + 6) ← distribute both parenthesis
= 12x³ - 20x² - 24x + 18x² - 30x - 36 ← collect like terms
= 12x³ - 8x² - 54x - 36
1/a + 1/b + 1/c = 1/x
Solve for x
Answers
Answer:
x=[tex]\frac{abc}{(bc+ac+ab)}[/tex]
Step-by-step explanation:
First, we need to remove the fractions on the left hand side, which we can do by multiplying each term by the lowest common multiple of the denominators. Since the denominators are all different (a,b and c), then the lowest common multiple is just all three multiplied together: abc
So, our original equation:
[tex]\frac{1}{a}+\frac{1}{b}+\frac{1}{c}=\frac{1}{x}[/tex] now becomes:
[tex]\frac{abc}{a}+\frac{abc}{b}+\frac{abc}{c}=\frac{abc}{x}[/tex]
Now we can simplify the fractions on the right hand side because each numerator can now be divided by its denominator:
[tex]bc+ac+ab=\frac{abc}{x}[/tex]
Now we can just rearrange the equation to solve for x by replacing the x with (bc+ac+ab), because if abc/x= bc+ac+ab, then abc/bc+ac+ab=x, as x and bc+ac+ab multiply to abc:
[tex]x(bc+ac+ab)=abc[/tex]
[tex]x=\frac{abc}{bc+ac+ab}[/tex]

The current Powerball jackpot is estimated to be $193 million. The Powerball lottery is decided every Wednesday and Saturday night by drawing five white balls out of a drum with 69 balls and one red ball out of a drum with 26 red balls. The Powerball jackpot is won by matching all five white balls in any order and the red Powerball. Each ticket costs $2. A ticket is defined as a set of five white and 1 red number.
Answers
Answer:
"2.660503478" would be the right answers to the key statement.
Step-by-step explanation:
Drawing 5 balls out of 69 can be done in ([tex]\frac{69}{5}[/tex])
= [tex]\frac{69\times 68\times 67\times 66\times 65}{5!}[/tex]
Drawing 1 ball out of 26 red balls can be done in ([tex]\frac{26}{1}[/tex])
= [tex]26[/tex]
Then the chance of drawing 5 out of 69 balls including 1 out of 26 red balls and then both matching the jackpot
= [tex]\frac{1}{11238513\times 26}[/tex]
= [tex]\frac{1}{292201338}[/tex]
Since the sum of the jackpot is $193-106 and then one ticket costs $2, the estimated value of buying one ticket again for jackpot is $2.
= [tex]\frac{1}{292201338}\times 193\times 10^6+\frac{292201338-1}{292201338}\times 2[/tex]
= [tex]2.660503478[/tex]

x < 50
Step-by-step explanation:
No more means that it cannot equal 50. Therefore we can remove the 1st two options.
We now have the 3rd option and 4th option to choose from.
The 4th option is incorrect because the inequality is saying that a number is greater than 50.
∴ x < 50 is our answer.

find all missing variables and measures of each angle
Answers
Answer:
y = 21
x = 48
Step-by-step explanation:
for y:
5y - 17 + 2y + 50 = 180
add like terms
7y + 33 = 180
subtract 33 from 180
7y = 147
divide 7 from 147
y = 21
for x:
x + 44 + 7x -248
add like terms
8x - 204 = 180
add 204 to 180
8x = 384
divide 8 from 384
x = 48
now plug it in to find angle measurements:
for y:
5 (21) - 17 = 88°
7 (48) - 248 = 88°
for x:
2 (21) + 50 = 92°
48 + 44 = 92°

x= square root of 2x-1
Step-by-step explanation:
First you move the 3 to the right side of the equation and since it was multiplied; you have to divide it making it 2x-1.
Then, you have to square it so you can get x by itself and since 2x and -1 do not have a square root you just leave it.
