ANSWER

7.26451 correct  to 3 decimal places is 7.265


EXPLANATION

We start counting from the first number after the decimal point.

So starting from 2, we count 3 decimal places to the right and land on 4.


Next, we check to see if the number after 4, is greater or equal 5, then we round up, else we round down.


Since that number is 5, it is greater than or equal to 5.


Therefore we round up to obtain 7.265

Select the equations where x = 8 is the solution. Select all that apply (select 3).
seraphim [82]

Answer:

Step-by-step explanation:

1. x - 2 = 10

x = 10 + 2 = 12

2. 40 = 5x

40/5 = x

x = 8

3. x/2 = 8

Multiply by 2 on both sides

x = 16

4. x + 14 = 24

x = 24 - 14 = 10

5. x + 2 = 10

x = 10 - 2 = 8

6. x/8 = 1

Multiply by 8 on both sides

x = 8

No 2 5 and 6 is the correct answer

Angelica says the tangent is the ratio of the length of the leg opposite angle A ∠ A over the length of the leg adjacent to angl
Tpy6a [65]

Based on the trigonometry ratios and the Pythagorean theorem both of them were incorrect.

Cos A = 4/5; Sin A = 3/5

<h3>What is the Trigonometry Ratios?</h3>

The Trigonometry ratios relates the length of the sides of a right triangles. They are given as:

  • Sine ratio, sin ∅ = opp/hyp
  • Cosine ratio, cos ∅ = adj/hyp
  • Tangent ratio, tan ∅ = opp/adj.

<h3>What is the Pythagroean Theorem?</h3>

If two sides of a right triangle are known the third side can be determined using the Pythagorean theorem, which is given as, c² = a² + b², where and b are legs, and c is the hypotenuse of the right triangle.

1. Given that tan A = 3/4, it is not necessarily true that BC MUST have a length of 3 units, and AC MUST have a length of 4 units, because:

If BC = 9 units and AC = 12 units, the it will give us the same tangent ratio as:

tan A = 9/12 = 3/4.

Therefore, Angelica's mistake is stating that BC MUST be 3 units, and AC MUST be 4 units.

2. Knowing two length of the sides of a right triangle is enough information needed to find the length of the third side using the Pythagorean theorem, so Graceilla is incorrect.

3. Find AC using the Pythagorean theorem:

AB = √(3² + 4²)

AB = 5 units.

Cos A = adj/hyp = AC/AB

Cos A = 4/5

Sin A = opp/hyp = BC/AB

Sin A = 3/5

What is the first step in the construction of a line perpendicular to AB←→ and passing through an external point M? Assume that
Lana71 [14]

Answer: A is the correct option "Place the compass needle on M and, keeping the compass width the same, draw two arcs that intersect AB←→".

Step-by-step explanation:

In the construction of a line perpendicular to AB←→ and passing through an external point M the first step must be"Place the compass needle on M and, keeping the compass width the same, draw two arcs that intersect AB←→". After that you can draw arcs from intersection points (keeping the compass width same as before) to the opposite side of M, name it as N than use straightedge to draw line passes through M and n that would be perpendicular line to AB.

Answer:   a) 11

<u>Step-by-step explanation:</u>

\sqrt{x-2}=x-8\\\\\\\text{Square both sides:}\\(\sqrt{x-2})^2=(x-8)^2\\\\\\\text{Simplify:}\\x-2=x^2-16x+64\\\\\\\text{Subtract x and add 2 to both sides:}\\0=x^2-17x+66\\\\\\\text{Factor the quadratic equation:}\\0=(x-6)(x-11)\\\\\\\text{Apply the Zero Product Property and solve for x:}\\0=x-6\qquad 0=x-11\\x=6\qquad \qquad x=11\\\\\\\text{Verify:}\\\sqrt{6-2}=6-8\qquad \qquad \sqrt{11-2}=11-8\\\sqrt4=-2\qquad \qquad \qquad \quad \sqrt9=3\\2\neq-2\qquad \qquad \qquad \qquad 3=3

6 is NOT a valid solution,  11 IS a valid solution
