Answer:
Y=-x
Step-by-step explanation:
Y=mx+c
y=3, x= -3, m=-1
(-1)(-3)=3
3-3=0
S0,
c=0
y=-x
The linear function representing the above function is
F=0.4x+2
Step-by-step explanation:
Let the total monthly cost be represented as $ F
Let the number of songs downloaded in a month be x
Given: cost of downloading one song= $ 0.40
Monthly subscription fee (one time monthly) = $ 2
Hence total monthly cost-
Total monthly cost= cost of downloading “x” songs + monthly subscription fee
Total cost of downloading “x” songs monthly= number of songs downloaded* cost of downloading one song
Total cost of downloading “x” songs monthly=$ 0.4x
Hence Total monthly cost= 0.4x + 2
We have assumed total monthly cost as “F”
F=0.4x+2
The height of the blue bar should be 14%.
The height of the red bar should be 20%.
Answer:
197.9
Step-by-step explanation:
The formula for circumference is 2(pi)r and r is the radius
The diameter is two times the size of the radius, so by dividing the diameter by two, you can get the radius
So, r=63/2
r= 31.5
That means that 2(pi)(31.5) is the circumference
2(pi)(31.5) = 197.9 (rounded to the nearest tenth)
Answer:
16
Step-by-step explanation:
How many times more intense is an earthquake measuring 6.8 on the Richter scale than one measuring 5.6?
Given:
Earthquake 1 : magnitude = 6.8
Earthquake 2: magnitude = 5.6
The intensity of an earthquake
I1 / I2
log I1 /s = 6.8
log I2 /s = 5.6
(log I2 /s) - (log I1 /s) = 6.8 - 5.6
(log I2 /s) - (log I1 /s) = 1.2
log(I2 / I1) = 1.2
I2 / I1 = 10^1.2
I2 / I1 = 15.8489
= 16
6.8 earthquake is about 16 times more intense than earthquake measuring 5.6
