Answer: a
Answer:
8
Step-by-step explanation:
use pythagoras theorem
a^2+b^2=c^2
a^2+6^2=10^2
a^2=10^2-6^2
a^2=100-36

Answer:
a. 5^-3
b. 14^18
c. 8^9
d. 16^3
e. 21^-18
Step-by-step explanation:
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
(a^b)/(a^c) = a^(b-c)
(a^b)^c = a^(bc)
__
a) 5^(3-6) = 5^-3
b) 14^(3·6) = 14^18
c) 8^(3+6) = 8^9
d) 16^(6-3) = 16^3
e) 21^(3(-6)) = 21^-18

subtract 12a² + 15ab - 20b² from 15a² + 10ab + 8b²
help.
Answer:
3a^2 + 28b^2 - 5ab
Step-by-step explanation:
here's your solution
=> to subtract (12x^2 + 15ab - 29b^2) from
( 15a^2 + 10ab + 8b^2)
=> (15a^2 + 10ab + 8b^2) - (12a^2 + 15ab - 20b^2)
=> 15a^2 + 10ab + 8b^2 - 12a^2 - 15ab + 20b^2
=> 15a^2 - 12a^2 + 8b^2 + 20b^2 + 10ab - 15ab
=> 3a^2 + 28b^2 - 5ab

Answer:
-4x + y + 6z
Step-by-step explanation:
Combine like terms (Terms with the same variable):
(2x + 5y - z) + (-6x - 4y + 7z)
Add straight across:
2x - 6x = -4x
5y - 4y = y
-z + 7z = 7z - z = 6z
-4x + y + 6z is your answer.

Calculate the length of the side LN given the following data for 37°.
Sin 37° = 0.602
Cos 37° = 0.790
Tan 37° = 0.754
pls help ASAP
Answer:
It is given that,
Sin 37° = 0.602
Cos 37° = 0.790
Tan 37° = 0.754
To find:
The length of side LN.
Solution:
In a right angle triangle,
[tex]\sin\theta =\dfrac{Perpendicular}{Base}[/tex]
Using this in triangle LMN, we get
[tex]\sin (37^\circ) =\dfrac{LM}{LN}[/tex]
[tex]0.602=\dfrac{6}{LN}[/tex]
[tex]0.602LN=6[/tex]
Divide both sides by 0.602.
[tex]LN=\dfrac{6}{0.602}[/tex]
[tex]LN=9.966777[/tex]
[tex]LN\approx 9.97[/tex]
Therefore, the correct option is C.
whats the ninth term of 25 20 15 10 5
Given:
The sequence is 25, 20, 15, 10, 5.
To find:
The ninth term of the given sequence.
Solution:
We have,
25, 20, 15, 10, 5
It is an AP because the difference between two consecutive terms are same.
Here,
First term (a) = 25
Common difference (d) = 20-25
= -5
The nth terms of an AP is
[tex]a_n=a+(n-1)d[/tex]
Where, a is the first term and d is the common difference.
Putting a=25, n=9 and d=-5 to get the 9th term.
[tex]a_9=25+(9-1)(-5)[/tex]
[tex]a_9=25+(8)(-5)[/tex]
[tex]a_9=25-40[/tex]
[tex]a_9=-15[/tex]
Therefore, the ninth term of the given sequence is -15.

A stadium with 75 rows has 10 seats the 1st row, 15 in the 2nd, 20 in the 3rd and so on.
How many seats are in the 75th row? How many seats are in the stadium?
Answer:
380
Step-by-step explanation:
This is an airthmatic sequence
we can use the following equation to find the nth term
a₁+(n-1)d
where the common difference (d) is 5
and the first term (a₁) is 10
and n is 75
we have
10+(75-1)*5
10+370
380
