2. Simplify ((–3)2)3
Answer:
-18
Step-by-step explanation:
((-3)2)3
First, you multiply -3 and 2 which equals -6
-3·2=-6

Can someone please help me with this problem?
Answer:
[tex]sin(\theta)=\frac{40}{41} \\cos(\theta)=\frac{9}{41} \\tan(\theta)=\frac{40}{9}\\csc(\theta)=\frac{41}{40} \\sec(\theta)=\frac{41}{9} \\cot(\theta)=\frac{9}{40}[/tex]
Step-by-step explanation:
Notice we can use the Pythagorean theorem to find the measure of the unknown side via:
[tex]123^2=120^2+x^2\\x^2=729\\x=\sqrt{729} \\x=27[/tex]
and now, knowing all the sides, we can find all te trigonometric functions of the angle [tex]\theta[/tex]:
[tex]sin(\theta)=\frac{opp}{hyp} = \frac{120}{123} =\frac{40}{41} \\cos(\theta)=\frac{adj}{hyp} = \frac{27}{123} =\frac{9}{41} \\tan(\theta)=\frac{opp}{adj} = \frac{120}{27} =\frac{40}{9}\\csc(\theta)=\frac{41}{40} \\sec(\theta)=\frac{41}{9} \\cot(\theta)=\frac{9}{40}[/tex]
2x^2 + 3x = -5
Trying to find the solution,
Thank you.
Answer:
x = 1/2 or -2
Step-by-step explanation:
2x^2 +3x -2 = 0
(2x - 1) ( x + 2 ) = 0
(2x-1) = 0 ______ x = 1/2
or
(x +2 ) = 0 ______ x = -2

Can someone help me find the GCF of 35 and 63 please show your work thank you
The first step to find the gcf of 35 and 63 is to list the factors of each number. The factors of 35 are 1, 5, 7 and 35. The factors of 63 are 1, 3, 7, 9, 21 and 63. So, the Greatest Common Factor for these numbers is 7 because it divides all them without a remainder.
To sum up, the gcf of 35 and 63 is 7. In common notation: gcf (35,63) = 7.

The slope of QR is *4 and the slope of ST is
3
If QR I ST, determine and state the value of x.
Answer:
E. -1/2
Step-by-step explanation:
When two lines are said to be perpendicular to each other, the slope of one is the negative reciprocal of the other.
Therefore, given that [tex] \frac{x - 1}{4} [/tex] is the slope of [tex] \overline{QR} [/tex], and ⁸/3 is the slope of [tex] \overline{ST} [/tex], if both lines are perpendicular, it means that the slope of [tex] \overline{ST} [/tex] would be the negative reciprocal of the slope of [tex] \overline{QR} [/tex].
Therefore:
[tex] \frac{x - 1}{4} = -\frac{3}{8} [/tex]
Cross multiply
[tex] (x - 1)(8) = (-3)(4) [/tex]
[tex] 8x - 8 = -12 [/tex]
Add 8 to both sides
[tex] 8x = -12 + 8 [/tex]
[tex] 8x = -4 [/tex]
Divide both sides by 8
[tex] x = \frac{-4}{8} [/tex]
[tex] x = \frac{-1}{2} [/tex]
