Divide 36 by 45, then multiply the decimal by 100 to get the percent.
36 / 45 = 0.8
0.8 x 100 = 80
The answer is 80%
6/10 - 1/2...common denominator is 10
6/10 - 5/10 = 1/10 <==
Answer:
$3,364.86
Step-by-step explanation:
3287.9*(14.5%/12)=39.73
3287.9 +39.73 interest = 3,327.63 - 1,200 (payment)=2127.63
2127.63 x (14.5%/12)=25.71
2127.63 + 25.71 interest = 2153.34 - 1200 (payment)=953.34
953.34 x (14.5%/12)=11.52
953.34 + 11.52 interest = 964.86
1200 + 1200 + 964.86 = $3,364.86
Answer:
y = 2
y = 6
Step-by-step explanation:
The first thing to do is to find the turning point of the function. For this, derive and equal zero to expression
= 



x = 0 and x = -2
We have 2 inflection points.
Then we have 2 tangent lines:
At the point (0, 2)
Since it is a point of inflection, then the slope of this line is 0. Therefore the tangent line is:
y = 2.
At the point (-2, 6).
The slope of this line is 0.
The equation of the tangent line to the function is:
y = 6
Table
Number of donuts Price
1 $1.05
2 $ 2.1
3 $3.15
4 $4.2
5 $5.25
6 $6.3
10 $10.5
slope = (10.5 - 1.05) / 10 - 1
= 9.45 / 9
= 1.05
Equation
y - 10.5 = 1.05 (x - 10)
y = 1.05x - 10.5 + 10.5
y = 1.05x
For 40 donuts
y = 1.05(40)
y = $42
