If f(x)=2x-4, what would be the answer if f(3)-1??

Mathematics
1 answer:
Vinil7 [7]2 years ago
3 0

Answer:

1

Step-by-step explanation:

We have the function

f(x) = 2x - 4

and we want to know the value of f(3) - 1.

The first step is to find f(3) ; we can subtract 1 from it at the end! But what does f(3) mean?

Basically, we're saying <em>"what is the value of the function when </em>x = 3<em> ?"</em>

So, we simply replace x with 3 in the function, and we get:

f(3) = 2\times 3 - 4 = 2.

Finally, we subtract 1 to find f(3) - 1 = 1.

The area of a rectangular wall of a barn is 32 square feet. It’s length is 4 feet longer than the width. Find the length and wid
Gnom [1K]

Answer:

Step-by-step explanation:

Givens

Area = L * w

w = x

l = x  + 4

Area = 32

Solution

32 = x(x + 4)

32 = x^2 + 4x

x^2 + 4x - 32

(x + 8)(x - 4)

Only x - 4 is going to make any sense

x - 4 = 0

x = 4

The width is 4

The length is 4 + 4 = 8

4*8 = 32 which is the area.

In a unit circle, ø = 270º. Identify the terminal point and sin ø.
larisa [96]

Answer:

Terminal point (0, -1); sin Ø = -1 ⇒ A

Step-by-step explanation:

In the unit circle, Ф is the angle between the terminal side and the positive part of the x-xis

  • The terminal point on the positive part of the x-axis is (1, 0),which means Ф = 0° or 360° and cosФ = 1, sinФ = 0
  • The terminal point on the positive part of the y-axis is (0, 1),which means Ф = 90° and cosФ = 0, sinФ = 1
  • The terminal point on the negative part of the x-axis is (-1, 0),which means Ф = 180° and cosФ = -1, sinФ = 0
  • The terminal point on the negative part of the y-axis is (0, -1),which means Ф = 270° and cosФ = 0, sinФ = -1

In a unit circle

∵ Ф = 270°

→ By using the 4th rule above

∴ The terminal point is (0, -1)

∴ sinФ = -1

∴ Terminal point (0, -1); sin Ø = -1
