Answer:
see explanation
Step-by-step explanation:
Inequalities of the form | x | < a have solutions of the form
- a < x < a
Given
| x - 4 | < 3 , then
- 3 < x - 4 < 3 ( add 4 to the 3 intervals )
1 < x < 7
Thus x > 1 or x < 7
Answer:
The answer to your question is letter A
Step-by-step explanation:
Polynomial 4x¹⁰ + 9x¹⁰
To sum or subtract polynomials, just look for like terms and do the operations considering the rules of signs.
In this problem both terms are like terms, then we add the coefficients and write the variable without a change.
4x¹⁰ + 9x¹⁰ = 13x¹⁰
<span>2sin(x)cos(x) = sin(x)
2sin(x)cos(x) - sin(x) = 0
sin(x)(2cos(x) - 1) = 0
sin(x) = 0
x = 0, pi, 2pi
2cos(x) - 1 = 0
cos(x) = 1/2
x = pi/3, 5π/pi
x = 0, pi/3, pi, 5 pi/3, 2 pi
hope it helps

Answer:
The center is ( 5.3, -3.3) and 7 is the radius
Step-by-step explanation:
We can write the equation of a circle as
( x-h)^2 + ( y-k)^2 = r^2
Where ( h,k) is the center and r is the radius
(x - 5.3)^2 + (y + 3.3)^2=49
(x - 5.3)^2 + (y - -3.3)^2=7^2
The center is ( 5.3, -3.3) and 7 is the radius
