Answer:

7.8 cm and 25.3 cm

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

?² + 7² = 10.5²

?² + 49 = 110.25 ( subtract 49 from both sides )

?² = 61.25 ( take the square root of both sides )

? = \sqrt{61.25} ≈ 7.8 cm ( to 1 dec. place )

Then

P = 10.5 + 7 + 7.8 = 25.3 cm

Use the graph to determine the y intercept
mafiozo [28]

Answers:

  • y intercept:  9
  • zeros:  -3, -1, 1, 3

===============================================

Explanation:

The y intercept is where the curve crosses the y axis. The curve appears to do so just below y = 10, so y = 9 seems like a good estimate. I'm basing this off of the answer choices given. The y intercept always occurs when x = 0.

The zeros, aka roots or x intercepts, are where the curve crosses or touches the x axis. This occurs in four locations: x = -3, x = -1, x = 1 and x = 3. The x intercepts always occur when y = 0.

Find the volume of a cylinder if it is 2 feet tall and has a diameter of 1.5. Use 3.14 for pi.
olga55 [171]

Answer:

3.5325

Step-by-step explanation:

V = 3.14*(.75^2)(2)

You divide the diameter by 2 to get the radius which is 1.5/2 =.75

r=.75

h=2

and you use the equation for volume of cylinder which is V = pi x radius squared x height

∆ABC is reflected about the line y = -x to give ∆A'B'C' with vertices
Ilia_Sergeevich [38]
Since A‘(-1,1) is on the line y=-x, reflecting it about the line doesn't change its coordinate, so A's coordinate is (-1,1). Reflecting B'(-2,1) about y=-x switches both the sign and the number of x and y, so B=(-1,2), and C'(-1,0) becomes C(0,1). Drawing out the graph with the points and the line helps.
