Short Answer D
P(1) = 1(1+1)(2*1 + 1)/6
P(1) = 1(2)(2 +1) / 6
P(1) = 1(2)(3)/6
P(1) = 1
P(2) = 2(2+1)(2*2 + 1) / 6
P(2) = 2(3)(5) / 6
P(2) = 5 So this formula is adding as it goes along. To Find the Total all we need do is use the formula to calculate P(1) to P(7)
P(7) = 7*(7 + 1)(2*7 + 1)/6
P(7) = 7 * 8 * 15 / 6
P(7) = 7 * 4 * 5
P(7) = 140 <<<< Answer
yellow car = x
white cars = 9x ( 9 times as many white cars)
9x +x = 40
10x = 40
x = 40/10 =4
4 yellow cars
9*4 = 36 white cars
Answer:
$0.19
Step-by-step explanation:
If you divide $3.61 by 20 you will get 18.5. But my rounding to the nearest cent you get $0.19 because 4 and below let it go, 5 and above make it a dove. ( aka let it go up/fly) so in conclusion you get $0.19
Answer: The answer is (b) A constant with an exponent on it.
Step-by-step explanation: We are to select the correct statement from the given options that represents a characteristic of an exponential function.
We know that an exponential function is a function of the form
where b ≠ 0.
Here 'b' is a constant and the variable 'x' is called an exponent. Also, if b > 0, then the function shows an exponential growth and if b < 0, then the function shows an exponential decay.
Thus, an exponential function involves a constant with an exponent on it.
Thus, (b) is the correct option.
