Answer: (-2+√5), (-2-√5)
Step-by-step explanation:
<u>1.</u> Reference the formula: [(-b±(√b^2-4ac))/2a]
<u>2.</u> Plug in the values from the equation: [(-4±(√16+4))/2]
<u>3.</u> Simplify: [(-4±(√20))/2]
<u>4.</u> Simplify the root: [(-4±(2√5))/2]
<u>5.</u> Simplify the fraction: [-2±√5]
<u>6.</u> There's your answer: (-2+√5), (-2-√5)
The ratio of AC/AB is given by
1) Sin B
2)Cos A
Here is the inequality:
You're looking for x. To find it, you have to remove everything on the same side of the variable. The only thing with it is positive 6. To remove it, you have to do the opposite of it, which is -6, which is also the same as subtracting 6. Subtract 6 from both sides:
Now you have -2x. When you have a negative variable, the inequality sign changes. Change the sign:
You're looking for x alone. To leave x alone, you have divide both sides by -2 since the variable is -2x. Divide both sides by -2:
When dividing a negative number number by a positive or vice versa, the result is ALWAYS negative. That's why in your answer, it's -7.
Your answer is x > -7
GRAPH:
Answer:
Theoretical probability is what we expect to happen, where experimental probability is what actually happens when we try it out. The probability is still calculated the same way, using the number of possible ways an outcome can occur divided by the total number of outcomes.
Step-by-step explanation:
The probability is still calculated the same way, using the number of possible ways an outcome can occur divided by the total number of outcomes. As more trials are conducted, the experimental probability generally gets closer to the theoretical probability
Answer: x=14
Step-by-step explanation:
Subtract 2
from both sides of the equation.
X=16−2
Subtract 2
from 16
.
X=14
