Answer:
80%
Step-by-step explanation:
you add all 3 and divide by 3
Y = 5.50x + 21...where x is the number of months and y is the total cost
function notation is basically subbing in f(x) for y
so ur rule in function notation is : f(x) = 5.50x + 21 <==
Answer:It would be 3 1/4 from sunrise, yellow and 5 5/6 red from mango.
Answer:
The length in centimeters of the Panama Canal on Ana’s map is 16.4 cm
Step-by-step explanation:
we are given that
Ana drew a map of the Panama Canal. In the scale Ana used for the map, 4 centimeters represents 20 kilometers
so,
20 km =4 cm
now, we can find 1 km
we can divide both sides by 20
now, we can multiply both sides by 82
now, we can simplify it
we get
82 km =16.4 cm
So,
The length in centimeters of the Panama Canal on Ana’s map is 16.4 cm
Answer:
The answer to your question is: -3 and 7
Step-by-step explanation:
To know if a value is a zero of the polynomial is necessary to find the prime factors of 84.
84 2
42 2
21 3
7 7
1
Then, the possible values are ±1, ±2, ±3, ±7.
After that, we evaluate each value in the polynomial, if the result is zero, that number is a root of the polynomial.
Example
(-3)³ - 8(-3)² - 5(-3) + 84
-27 - 72 + 15 + 84
- 99 + 99 = 0
Then, -3 is a zero of the polynomial
(7)³ - 8(7)² - 5(7) + 84
343 - 392 - 35 + 84
427 - 427 = 0
Then, 7 is a zero of the polynomial
