Answer:
B
Step-by-step explanation:
Sin(A) = O/H
Sin(A) = 27/45
Sin(A) = 0.6
Answer:
x = 3 and x = -2
Step-by-step explanation:
The given equation is :
We need to solve the given equation.
We can solve it using Completing the Square method.
We take two numbers such that their product is -6 and sum is -1.
So,
so, the values of x are 3 and -2.
Answer:
d ≤3
Step-by-step explanation:
9−4d≥−3
Subtract 9 from each side
9-9−4d≥−3-9
−4d≥−12
Divide by -4, remembering to flip the inequality
-4d/-4 ≤ -12/-4
d ≤3
Answer:
24. x = 8.
25. x = -9, 10.
Step-by-step explanation:
The zeros of the functions are the solutions to the equation when y=0. To find the solution, factor each equation.
24. Look for two factors that multiply to 64 and add to -16. The factors are -8 and -8. Write them in binomial forms.
(x-8)(x-8)
So x = 8.
25. Look for two factors that multiply to -90 and add to -1. The factors are 9 and -10. Write them in binomial forms.
(x+9)(x-10)
So x = -9, 10.
