Answer:
-5x^4 +6x^3 -x +3
Step-by-step explanation:
First, eliminate parentheses.
(-4x^3+5x^2-x+3)-5(x^4-2x^3+x^2)
= -4x^3 +5x^2 -x +3 -5x^4 +10x^3 -5x^2
Then collect terms.
= -5x^4 +(-4+10)x^3 +(5 -5)x^2 -x +3
= -5x^4 +6x^3 -x +3

Find the surface area of a right cone that has a radius of 9 inches and a height of 12 inches. Round your answer to the nearest hundredth.
Answers
Answer:
SA= 678.24 in^2
Step-by-step explanation:
SA = (pi)(r^2) + (pi)(r)(l)
r = radius
h = height
l = slant height
Pi = 3.14
Slant height:
l^2 = h^2 + r^2
l = sqrt (144+81)
= 15
SA = (pi)(9^2) + (pi) (9) (15)
SA = 254.34 + 423.9
SA= 678.24 square inches
If the slant height of the cone is 15 inches. Then the surface area of the cone will be 678.58 square inches.
How do find the surface area of some object?Find the area that its outer surfaces possess. The Sum of all those surface areas is the surface area of the considered object.
If a right cone has a radius of 9 inches and a height of 12 inches.
Then the surface area of a right cone will be
The slant height is given as
l² = 9² + 12²
l² = 81 + 144
l² = 225
l = 15
Then the surface area will be
Surface area = πr² + πrl
Surface area = π x 9² + π x 9 x 15
Surface area = 81π + 135π
Surface area = 216π
Surface area = 678.58 square inches

An insurance agent earns a base salary of $28,000, a commission of 2% of sales, and receives an additional fee of $9 for each sale of an investment policy. The agent had total sales of $75,000 and 6 investment policies this month. Find the commission and fees earned. (There should be 2 separate answers)
Answers
Answer:
$54 for fees
$1500 for commission
$29554 in total
Step-by-step explanation:
They will have $28000 regardless.
The commission is 2% so you multiply 0.02 (which is equivalent to 2%) to $75000, so he earns $1500. He sold 6 sales so he you multiply 6 by $9 and you get $54.
I don't know exactly what your asking but

419 and 318 are whole numbers so you can cross those of the most
1/2 and 7/16 are the only options left
1 divided by 2 is 0.5
7 divided by 16 is 0.43
7/16 is then smaller than 1/2, because in decimal form, 0.43 is smaller than 0.5
Victor has 2 times as many as trophies as Dean. Together , víctor and Dean have 27 trophies . How many trophies does víctor have?
Answers
x = Dean
y = Víctor
Since Víctor has 2 times the trophies that Dean has, the amount of trophies Víctor has would be equal to 2x. Therefore,
y = 2x
The amount of trophies they have added together is 27. Therefore,
x + y = 27
We know that y = 2x, so we can substitute y for 2x in the equation x + y = 27. Therefore,
x + 2x = 27
Now solve for x.
x + 2x = 27
3x = 27
3x/3 = 27/3
x = 9
Dean has 9 trophies.
Since Víctor has 2 times the amount Dean has,
Víctor has 18 trophies
How can you estimaite [tex]\sqrt 40.[/tex]
Answers
9514 1404 393
Answer:
√40 ≈ 6 4/13 ≈ 6.31
Step-by-step explanation:
The estimate by linear approximation starts with the recognition that ...
40 = 36 +4 = 6² +4
and the difference from 36 to the next square, 7² = 49 is 49-36 = 13.
The linear approximation to √40 is ...
√40 ≈ 6 4/13 ≈ 6.31
__
There are various methods for improving this approximation. Perhaps the fastest improvement is obtained using the "Babylonian method." The next iteration is the average of this value and 40 divided by this value.
(82/13 +40/(82/13))/2 = 6 173/533 ≈ 6.3246 . . . . accurate to 4 decimal places
_____
Additional comment
When you write the value in terms of a square and a remainder:
n = s² +r
then the above linear approximation of √n can be written as ...
√n ≈ s +r/(2s+1)
Using the idea that a square root can always be represented by a continued fraction, we can continue the fraction one more iteration to give a slightly better approximation:
√n ≈ s +r(2s+1)/(2s(2s+1) +r)
For the case at hand, this gives √40 ≈ 6+52/160 = 6 13/40 = 6.325, accurate to 3 decimal places. Additional iterations using the continued fraction idea can be had using ...
n'' = s + r/(s +n') . . . . . where n' is an approximation of the root and n'' is a better approximation. This does not converge as fast as the Babylonian method, but may be easier to calculate on some calculators.
Arrange these numbers in order from least to greatest.

Solution:
Assuming there are no other parts,
the Whole = A + B is the denominator:
Whole = 14 + 18 = 32
Part A = 14 and Part B = 18 are numerators for each fraction.
The fractions are then:
14/32 and 18/32
Meaning:
Part A is 14/32 of the whole
Part B is 18/32 of the whole
Reducing the fractions, it is also true that:
Part A = 7/16 of the whole
Part B = 9/16 of the whole
