Answer:
22+1
Step-by-step explanation:
Answer: The freezing temperature of water in degrees Fahrenheit is 32.
Step-by-step explanation:
Hi, to answer this question we have to replace the value of the variable "C" in the formula F(C), by the value given in Celsius that water freezes.
Mathematically speaking:
F(C) = 32 +1.8 C
F (0) = 32 +1.8 (0)
Solving for F (Fahrenheit), since any number multiplied by zero equals zero:
F = 32
The freezing temperature of water in degrees Fahrenheit is 32.
1) y=0.94x+12.5
for x=40 months
y=0.94*40+12.5=50.1------------------ > *1000=$50100
the answer is $50100
2) the companys sales increase per months is equal to the slope of the equation of the line
y=0.94x+12.5--------------------- > y=mx+b
the slope m=0.94
094*1000=940 $/month
the answer is 940 $/month
3) the equation of the trend line is
k=mj+b
<span>I take two points of the graph
</span>point A(2,24) point B(10,8)
m=(k2-k1)/(j2-j1)------------- >(8-24)/(10-2)=-2
m=-2
then
k=mj+b--- >for point B(10,8)
8=-2*(10)+b------ > b=28
k=-2j+28
the answer is k=-2j+28
4) the line which is a model lineal for the data
is the one shown in the attached figure (because <span>that line shows the estimated values closest to the real values)</span>
F=I(1+rt), F=final amount, I=initial amount, r=rate, t=time
Here I=$5000, r=(4/100)=0.04 so
F=$5000(1+0.04t) so after 5 years...
F=$5000(1+0.2)
F=$6000
