Answer:
The correct option is;
D. x = -1.38 and 0.82
Please find attached the combined function chart
Step-by-step explanation:
The given equation is x³ + 3 = -x⁴ + 4
Plotting the equation using Excel, we have;
f(x) = x³ + 3, h(x) = -x⁴ + 4
x f(x) h(x)
-1.4 0.256 0.1584
-1.39 0.314381 0.26699
-1.38 0.371928 0.373261
-1.37 0.428647 0.477246
-1.36 0.484544 0.57898
Which shows an intersection at the point around -1.38
x f(x) h(x)
0.77 3.456533 3.64847
0.78 3.474552 3.629849
0.79 3.493039 3.610499
0.8 3.512 3.5904
0.81 3.531441 3.569533
0.82 3.551368 3.547878
0.83 3.571787 3.525417
Which shows the intersection point around 0.82
Therefore, the correct option is x = -1.38 and 0.82
From the graphing calculator the intersection point is given as
x = -1.3802775691 and 0.81917251339.
Answer:
Both sizes are better because they cost Same.
Step-by-step explanation:
Consider the provided information.
A coupon offers $1.00 off the 16
Quantity Price
Pint 16 $3.98
Quart 32 $5.98
If he gets $1 off for the 16-ounce size. The price will be:
3.98-1=2.98
He needs to pay $2.98 for 16-ounce pint.
Now find which one is better by calculating the unit rate.
Therefore, the cost of 1lb would be $0.186
For Quart 32 find the unit rate as shown:
Therefore, the cost of 1lb would be $0.186
Hence, both of the size are better as the unit rate is same.
