Answer:
2.25
Step-by-step explanation:
Given the cost model:
C(l) = l3 – l2 + l + 2.5
l = Length fo package
The length of a package that cost $11.00
11 = l³ - l² + l + 2.5
From the table given :
Length of mail which cost $11 will just be slightly greater Than 2 as the cost of 2 length mail cost 8.50
Taking l as 2.20
2.2^3 - 2.2^2 + 2.2 + 2.50 = 10.508
Taking a slightly higher value :
Put l = 2.25
2.25^3 - 2.25^2 + 2.25 + 2.50 = 11.078
Ww can conclude that the length of mail would be 2.25
Answer:
Surface area = 92 ft²
Step-by-step explanation:
Formula to find the surface area of a rectangular prism is,
Surface area = 2(lb + bh + hl)
Here, l = length of the prism
b = width of the prism
h = height of the prism
By substituting the measures of the sides given in the picture,
Surface area = 2(2×3 + 3×8 + 8×2)
= 2(6 + 24 + 16)
= 2(46)
= 92 square feet
Therefore, surface area of the given rectangular prism is 92 ft².
Answer:
Answer:
As x→∞ , f(x)→-∞
As
x→-∞ , f(x)→∞
Step-by-step explanation:
End behavior is determined by the degree of the polynomial and the leading coefficient (LC).
The degree of this polynomial is the greatest exponent, or
3
.
The leading coefficient is the coefficient of the term with the greatest exponent, or
2
.
For polynomials of even degree, the "ends" of the polynomial graph point in the same direction as follows.
Even degree and positive LC:
As x→∞ , f(x)→∞ As x→∞, f(x)→∞
Even degree and negative LC:
As x→−∞ , f(x)→−∞
As
x→∞ , f(x)→−∞
4(x+3)=7
The mistake is with his final answer, he wrote down 4x=1.
When you do 4(x)4(3), the answer is completely different from what Andre said. He did wrong calculations.
4x3=12
7-12= -5
Which means it should be 4x=-5 as the final answer.
Hey!!
here is your answer >>>>
If there are 8 students, and who have 3/4 the cake to share equally, we will have to divide 3/4 with 8.
which is( 3/4)/(8)
Now, we will have to take a reciprocal, we get,
(3/4)(1/8)
which is 3/32
which is
Each student gets, 3/32 of the cake!
Hope my answer helps!
