Answer: Third Option
yes; k = 4 and y = 4x
Step-by-step explanation:
Observe in the values of x and y given that when x decreases the variable-y also decreases.
Then the variation is direct.
Then, if between any two points of the function, the rate of variation k remains the same then the variation is constant.
We can test whether these conditions are met by using the given points.
(-2, -8) and (-4, -16)
The rate of variation k for these points is:
Now we calculate the variation rate for the points
(-4, -16) and (-6, -24)
The rate of variation is constant and equal to 4.
Then the answer is yes; k = 4 and y = 4x
Answer:
the answer is 45
Step-by-step explanation:
every triangle has to add up to 180 so 25 + 45 is 70 and 70 + 110 is 180
Answer:
Step-by-step explanation:
<u>Given formula:</u>
<u>Solving for n:</u>
- S = 180(n - 2) ⇒ open parenthesis
- S = 180n - 360 ⇒ isolate n
- 180n = S + 360 ⇒ divide both sides by 180
- n = (S + 360)/180
Answer:
The volume = 5 276.66928645188 cm³
Step-by-step explanation:
let V be the volume of the given sphere.
V = (4/3)×π×r³ ,where r is the radius of the sphere
r = 21.6÷2 = 10.8 cm
Then
V = (4÷3)×π×(10.8)³
= 5 276.66928645188 cm³
