$12.94 is what the CD would be before the 6% sales tax
Answer:
undefined
Step-by-step explanation:
We can find the slope of a line using two points by
m = (y2-y1)/(x2-x1)
= (-9- -4)/(-4 - -4)
= (-9+4)/(-4+4)
= -5/0
When we divide by zero, our solutions is undefined
The slope is undefined
The answer is 54 square units.
let the vertex in quadrant I be (x,y)
<span>then the vertex in quadratnt II is (-x,y) </span>
<span>base of the rectangle = 2x </span>
<span>height of the rectangle = y </span>
<span>Area = xy </span>
<span>= x(27 - x</span>²<span>) </span>
<span>= -x</span>³<span> + 27x </span>
<span>d(area)/dx = 3x</span>²<span> - 27 </span><span>= 0 for a maximum of area </span>
<span>3x</span>²<span> = 3 x 3</span>² = <span>27 </span>
<span>x</span>²<span> = 9 </span>
<span>x = ±3 </span>
<span>y = 27-9 = 18 </span>
So, the largest area = 3 x 18 = 54 square units
Answer:
Inequality symbol = ≥
Solution = d≥4
Step-by-step explanation:
If a family drives 350 miles per day, then;
1 day = 350 miles
To determine the number of days they will use to reach at least 1400mles
d days = 1400miles
Divide both expressions
1/d = 350/1400
Cross multiply
350 * d = 1400
350d = 1400
Since we are told that it ia at least 1400miles, this means the total miles can be greater than 1400. Hence the correct inequality sign to use will be a greater than or equal to sign(≥).
The expression above becomes 350d ≥ 1400
Divide both sides by 3350
350d ≥ 1400/350
d≥ 4
Hence the solution that represent the situation is d≥ 4
