How to estimate

Mathematics
1 answer:
monitta3 years ago
6 0
4 3/5 ≈ 5
1 1/5 ≈ 1

(4 3/5) +(1 1/5)
≈ 5 +1
≈ 6 . . . . . . . . . . . the estimated sum rounded to whole numbers

_____
Additional information:
As a refinement to your estimate, you can estimate the error. The first number is 2/5 less than 5. The second number is 1/5 more than 1, so the errors add up to
.. (2/5) +(-1/5) = 1/5

That is, your "estimate" of 6 is actually too high by 1/5. You can refine that estimated value by subtracting 1/5. 5 4/5 would be a closer "estimate."

y -----> (y + 3)

( - 1.5, 0) ------> (- 3.5, 3)

(- 1, - 1) -----> ( - 3, 2)

(0, - 2) ------> ( - 2, 1)

(1, - 1) -----> ( - 1, 2)

The tangent ratio is the ratio of the side _____ the acute angle over the side ______ to the acute angle.
juin [17]
For this case what you have to take into account is the following trigonometric definition:
 Tan (x) = (C.O) / (C.A) 
 Where,
 x: angle
 C.O: opposite leg
 C.A: Adjacent cateto.
 We have then:
 The tangent ratio is the ratio of the side opposite the angle of the side to the angle.
 Answer: 
 opposite, adjacent

Describe the roots of the equation shown below.
Olegator [25]

Answer:

B. There is one real, double root

Step-by-step explanation:

For ax² + bx + c = 0, the discriminant is b² − 4ac.

If the discriminant is positive and a perfect square, there are two real, rational roots.

If the discriminant is positive and not a perfect square, there are two real, irrational roots.

If the discriminant is 0, there is one real, double root.

If the discriminant is negative, there are two complex roots.

Here, a = 64, b = -16, and c = 1.

b² − 4ac

= (-16)² − 4(64)(1)

= 0

The discriminant is 0.  Therefore, there is one real, double root
