Answer:
- opposite: 4.88
- adjacent: 14.18
Step-by-step explanation:
SOH CAH TOA is a mnemonic intended to remind you of the relevant trig relations.
Sin = Opposite/Hypotenuse ⇒ opposite = 15×sin(19°) ≈ 4.88 units
Cos = Adjacent/Hypotenuse ⇒ adjacent = 15×cos(19°) ≈ 14.18 units
Answer:
Point C would now be (6,0)
Point B would now be (0,-7)
Point A would now be (2,-6)
Answer:
{-2, 1, 2}
Step-by-step explanation:
F(x) = x³ - x² - 4x + 4 is factorable as follows:
F(x) = x²(x - 1) - 4(x - 1). (x - 1) is a common factor. Factor it out:
F(x) = (x - 1)(x² - 4)
x² - 4 can be factored further:
F(x) = (x - 1)(x - 2)(x + 2)
The possible roots of F(x) are {-2, 1, 2}.
Answer:
y = 21
Step-by-step explanation:
x = 5
y = 5 (5) - 4
y = 25 - 4
y = 21
(5 , 21)
Hope this helps!
Answer:
y > -5x + 3
Step-by-step explanation:
Answer:
y > –5x + 3
Step-by-step explanation:
we know that
1) The solution of the inequality is the shaded area above the dashed line
so
The linear inequality could be
y > –5x – 3
y > –5x + 3
y > –3x + 5
2) The slope of the dashed line is negative ----> the three options have slope negative
3) The y-intercept of the dashed line is (0,3)
therefore
The linear inequality is
y > –5x + 3
...............................................................................................................................................
Answer:
Step-by-step explanation:
To find the linear inequality , Let pick two points from the graph
Lets pick (0,3) and (1,-2)
Lets find out slope using the points
Slope m= -5
y intercept b= 3
Equation of the line is y=mx+b
Now we look at the shaded part. we use test point (0,0)
(0,0) is not in the shaded region
0 >3 is false
