Answer: 5.76
Step-by-step explanation:
0.09 x 64 implies 0.09 in 64 places
To solve this, Multiply 0.09 x 64
It gives 5.76
Answer:
The graph will show an initial value that is lower on the y-axis
Step-by-step explanation:
The exponential function has the next general form:
where <em>a</em> is the initial amount and <em>b</em> is the base.
If the <em>a</em> value in the function is decreased, but remains greater than 0, the y-intercept of the curve decrease.
Answer:
<em>8,748 </em>
Step-by-step explanation:
f(x) = 
<em>f(6)</em> = 
= 12 × 9³ = 12 × 729 = <em>8,748</em>
We are given with the costs: 4$ entrance fee and 3$ per pound of pumpkin picked. The total amount of costs is represented by the function: y = 4 + 3x where y is the total cost of a person entering the patch and x is the number of pounds of pupmkin bought.
Cramer's rule works as follows:
x+3y=16
3x+y=8
Then
x=Dx/D
y=Dy/D
where Dx,Dy,D are 2x2 matrices formed from of coefficients and right hand side.
D=
1 3
3 1
=1-9=-8
Dx=matrix D with first column replaced by the vector [16,8]=
16,3
8 1
=16-24
=-8
Dy=matrix D with second column replaced by the vector [16,8]=
1 16
3 8
=8-48
=-40
Therefore
x=-8/-8=1
y=--40/-8=5
Check:
x+3y=1+3(5)=16
3x+y=3(1)+5=8 ok.
