Mathematics
1 answer:
Brums [2.3K]3 years ago
5 0

Answer: C

Step-by-step explanation:

Looking at the triangle, we see that the angles are the same. This tells us the triangle is an isosceles triangle. That means the two adjacent sides are equal to each other.

4x+23=10x-1       [subtract both sides by 4x]

23=6x-1               [add both sides by 1]

24=6x                  [divide both sides by 6]

x=4

Now, we know that x=4.

What is the length of BC? Round to the nearest tenth.
emmasim [6.3K]

9514 1404 393

Answer:

  (c) 14.5 cm

Step-by-step explanation:

The relevant trig relation is ...

  Sin = Opposite/Hypotenuse

  sin(65°) = BC/BA

  BC = BA·sin(65°) ≈ (16 cm)·0.9063 ≈ 14.501 cm

  BC ≈ 14.5 cm

_____

<em>Additional comment</em>

As is often the case, a simple estimate is all that is needed to identify the correct answer choice.

You only need to know how the long side of a right triangle compares to the others. In an isosceles right triangle, both legs are √2/2 ≈ 0.71 times the hypotenuse. The long side of a right triangle will never be shorter than that. This means the long side must be greater than about 11.2, and cannot be greater than 16. There is only one answer choice in that range.

Suppose that f is a sine function ... look at the picture
Triss [41]

Answer:

f(3π/4) = -π

A = π

b = 2

Step-by-step explanation:

Given that the function follows the form: f(x) = A sin(bx), then f(0) = 0. Given that the period is π, then at x = π/4 the function reaches a maimum, at x = π/2, f(x) = 0, and at x = 3π/4, f(x) reaches a minimum, which have to be π*(-1) = -π

Given the general equation: f(x) = A sin(bx), its period is calculated as:

period = 2π/b

which is equal to π, then:

2π/b = π

b = 2

Replacing x = π/4 into the equation of the function, we get:

A sin(2(π/4)) = π

A sin(π/2) = π

A = π

10×+73=7 solve two step equations by using inverse operations. and use inverse operations to solve the equations ​
MrMuchimi

Answer:

x=-67/10

Step-by-step explanation:

What you have to do is first subtract 73 from both sides. that makes it 10x=7-73. That is 10x=-67. Then divide both sides by 10. That is x=-67/10
