Answer:
f(-2) = 50
Step-by-step explanation:
What f(-2) simply means is that you will substitute -2 in f(x) = 8x^2 − 14x − 10.
That is wherever you see x you replace it by 2
f(-2) = 8(-2)² - 14(-2) - 10
= 8(4) + 28 - 10 (note (-2)² = -2 × -2 = 4. Also, -14 × -2 = 28)
= 32 + 28 - 10
= 60 -10
=50
Therefore f(-2) = 50
Answer:
f(- 2) = 50
Step-by-step explanation:
To evaluate f(- 2) substitute x = - 2 into f(x)
f(- 2) = 8(- 2)² - 14(- 2) - 10
= 8(4) + 28 - 10 = 32 + 28 - 10 = 50
Answer:
The answer is that the team has to have 25 wins.
Step-by-step explanation:
since the ratio is 2 losses to 5 wins, if you divide 10 by 2, you get 5. Multiply 5 by 5, since it is the other side of the ration, and you'll get 25 wins.
25:10 = 5:2
Answer:25
Step-by-step explanation:
The value of sinA in the triangle is 0.6. Then the correct option is A.
Trigonometry is the branch of mathematics that set up a relationship between the sides and angle of the right-angle triangles.
In the given triangle base is 8 and the perpendicular is 6 units. To calculate sinA we need hypotenuse and then use the Pythagorean theorem.
H² = P² + B²
H² = 6² + 8²
H² = 36 + 64
H² = 100
H = 10
The angle sinA is the ratio of perpendicular and hypotenuse.
sinA = P / H
sinA = 6 / 10
sinA = 0.6
Hence, the correct answer is option A.
