There are two answers to this question
the first possible answer is 5, 6, and 7 and the second possible answer is -4, -3, and -2
Step-by-step explanation:
let the three numbers be (x-1), x, and (x+1)
the product of the smallest and largest number is 17 more than 3 times the middle number, or
(x-1)(x+1) = 3x+17, or
x^2-1 = 3+17, or
x^2-3x-18 = 0
(x-6)(x+3) = 0
So x = 6 or -3
Then just subtract one and add one to get the other integers. the three numbers are 5, 6, and 7 or -4, -3, and -2
The answer is C.
40:20 is equal to 2:1
Answer:
The drawing will fit the index card
Step-by-step explanation:
The scale use by Shannon is
1 inch represent 0.5 feet.
Thus, the length of the car in the drawing is 12 * 0.5 = 6 inch.
The size of the paper is 5 inch by 7 inch
Hence, considering the longest side of paper representing the length of the car, it can be said that the drawing will fit the index card.
The approximate equation is n = (ln 6)/10 and approximate value is n = 0.179.
<h3>What is Exponential equation?</h3>
In mathematics, an exponential function is a function of form f (x) = aˣ, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0.
Here, given equation; (we are using n in place of t)
-5.e¹⁰ⁿ = -30
On dividing -5 both sides, we get
-5.e¹⁰ⁿ/-5 = -30/-5
e¹⁰ⁿ = 6
Taking 'ln' on both side, we get
10n = ln 6
n = (ln 6)/10
n = 1.791759/10
n = 0.179
Thus, the approximate equation is n = (ln 6)/10 and approximate value is n = 0.179.
