Answer:
3x^2+4x+1
Step-by-step explanation:
Given the polynomial function 4x + 3x^2 - 1
Rearranging in descending order means that we are to arrange the degree power from the highest to the lowest.
The term with the highest degree is 3x^2
Followed by 4x
Then the constant 1
Adding according to the descending powers
The polynomial in descending order will be 3x^2+4x+1

A triangular-shaped sign has a base of 15 ft, and a height of 8 ft. What is the area of the sign?
Answer:
60ft²
Step-by-step explanation:
Area of a triangle = 1/2×base×height
=1/2×15×8
=60
A triangle has sides with lengths 8, 15, and 17.
Approximate the acute angles in this triangle.
Pythagoras is the sum of the square of two sides is equal to the square of the longest side. Then the acute angle of the given triangle is 28.07 degrees.
What is a right-angle triangle?It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.
A triangle has sides with lengths 8, 15, and 17.
By Pythagoras theorem, we have
H² = P² + B²
17² = 8² + 15²
289 = 64 + 225
289 = 289
The dimension of the triangle satisfies the Pythagoras theorem. Hence the triangle is a right-angle triangle.
Then the acute angle will be
[tex]\rm \theta =Sin ^{-1} \dfrac{8}{17}\\\\\theta = 28.07^o[/tex]
Thus, the acute angle of the given triangle is 28.07 degrees.

Find the first five terms of the sequence defined below, where n represents the position of a term in the sequence. Start with n=1. 10n+10
Answer:
20,30,40,50,60
Step-by-step explanation:
The sequence is given by the relation as follows :
[tex]a_n=10n+10[/tex]
First term, n = 1
[tex]a_1=10(1)+10=20[/tex]
Second term, n = 2
[tex]a_2=10(2)+10=30[/tex]
Third term, n =3
[tex]a_3=10(3)+10=40[/tex]
Fourth term, n = 4
[tex]a_4=10(4)+10=50[/tex]
Fifth term, n = 5
[tex]a_5=10(5)+10=60[/tex]
So, the first five terms of the sequence are 20,30,40,50,60

The average grade Jared received on 4 tests was 94. If he drops his lowest test grade of 85, what will his new average be?
A.72.75
B.76
C.89.5
D.97
Pls help TT
Answer:
total points on the 4 tests- 94x4= 376
376- 85= 291
291/3= D. 97
Answer:
D. 97
Step-by-step explanation:
x = sum of 4 test grades Jared received
[tex]\frac{x}{4} = 94[/tex]
x = 376
If he drops lowest test grade of 85, then subtract 85 from Jared's sum of all test grades:
x - 85 --> 376 - 85
= 291
Now that one of his test grades are not considered, this means there are only 3 test grades to consider.
291 must be divided by 3 to get the average:
[tex]\frac{291}{3}[/tex] = 97
The answer is D) 97

Costs= (740)
Gross income= 600
Depreciation= (130)
EBIT= 470
Tax= (470*0.3)= (141)
Depreciation= 130
Net operating cash flow= $459
