How many roots does (x+10)^9 have. Please explain how u did it.
Answer:
This expression contains a one root (x= -10) of multiplicity 9
Step-by-step explanation:
Notice that this polynomial is given in factor form, since it is equivalent to 9 products of the same factor (x+10):
[tex](x+10)^9=(x+10)\,(x+10)\,(x+10)\,(x+10)\,(x+10)\,(x+10)\,(x+10)\,(x+10)\,(x+10)[/tex]
Therefore, there is a single root x = -10, since when x=-10 each of these binomial factors result in a zero.
In mathematical terms, such type of root is said to have multiplicity. And in this case, the multiplicity is "9" (the number of equal binomial factors of the polynomial form).
Answer:
9
Step-by-step explanation:
(x+10)^9 is the 9-degree polynomial so it has 9 roots
if it is equal to zero then it has 9 equal roots of x= -10

Which line has a slope 3/4
Line C shown in the graph has a required slope of 3/4.
Given that,
A figure is shown we have to determine a line that has a slope of 3/4.
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanФ where x in degrees.
m =(y₂ - y₁) / (x₂ - x₁) = tanФ
here,
The slope of the line A = ∞
The slope of the line D = 0
The slope of the line B = 4/ 3
The slope of the line C = 3/4
Thus, Line C shown in the graph has a required slope of 3/4.

If OP=17 and QP=6, what is OQ? First, complete the Segment Addition Postulate for this problem.
OQ + QP= BLANK?
Fill in what you know and solve for OQ
OQ= BLANK?
Answers:
OQ + QP = OP
OQ = 11
============================================================
Explanation:
The smaller pieces OQ and QP glue together to form the larger segment OP. This is effectively what the Segment Addition Postulate says. This only works if all three points are on the same single line segment.
We know that OP is 17, so QP = 6 adds to the other unknown piece to get 17. The other piece must be 11 units long. Algebraically you could write,
OQ + QP = OP
OQ + 6 = 17
OQ + 6-6 = 17-6 ... subtracting 6 from both sides
OQ = 11
OQ is 11 if OP=17 and QP=6. This is obtained by using Segment Addition Postulate.
What is Segment Addition Postulate ?If Q is between O and P, then OQ + QP = OP.
Find OQ + QP and OQ:
Given, OP=17 and QP=6
According to Segment Addition Postulate,
OQ + QP = OP
OQ + 6 = 17
OQ= 17-6 =11
OQ = 11
∴ OQ + QP =17 and OQ = 11
Hence the value of OQ is 11 when OP is 17 and QP is 6.

Purple Taxi has no pick-up fee, but charges $0.25 per mile. ABC Taxi charges $3 for pick-up and $0.15 per mile. Which inequality can be used to find the number of miles, n, for which the cost of a cab ride with Purple Taxi exceeds the cost of a cab ride with ABC Taxi? 0.25n≥3+0.15n 0.25n+3<0.15n 0.25n>0.15n+3 3+0.15n>0.25n
Answer:
0.25n>0.15n+3
Step-by-step explanation:
Hi, to answer this question we have to write an inequality:
Since Purple taxi charges 0.25 per mile, the cost of using Purple taxi is:
0.25n
Where n is the number of miles.
ABC Taxi charges $3 for pick-up and $0.15 per mile
So, the cost for using ABC taxi is equal to the fixed fee per pick up (3) , plus the cost per mile (0.15n)
3+0.15n
To find the number of miles, n, for which the cost of a cab ride with Purple Taxi exceeds the cost of a cab ride with ABC Taxi, the cost of a cab ride with purple taxi must be higher (>) than the cost of a cab ride with ABC taxi.
0.25n>0.15n+3

Two angles add to 90°. The larger angle is 12° more than five times the measure of the smaller angle. Find the measure of the two angles.
Answer:
13 and 77 degrees
Step-by-step explanation:
First, you start by subtracting 12 from the 90..
90 - 12 = 78
then, take 78 and divide it by 6.
78/6 = 13
13 is the measure of your smaller angle.
multiply 13 by 5 and then add 12 to find the measure of the larger angle.
13 x 5 = 65
65 + 12 = 77
77 is the measure of your larger angle.
Find the value of x in the following quadrilateral.
Answer:
see below
Step-by-step explanation:
Because the sum of all angles in a quadrilateral is 360° we have:
90 + 101 + 12x + 3 + 9x - 2 = 360
21x + 192 = 360
21x = 168
x = 8°
Answer:
The value of x is 8.
Step-by-step explanation:
Given that total angles in a quadrilateral is 360°. So in order to find x, you have to add up all the angles together to make it equals to 360° :
[tex]101 + 12x + 3 + 9x - 2 + 90 = 180[/tex]
[tex]192 + 21x = 360[/tex]
[tex]21x = 360 - 192[/tex]
[tex]21x = 168[/tex]
[tex]x = 168 \div 21[/tex]
[tex]x = 8[/tex]
