Scalar and matrix multiplication Find the product:

Mathematics
1 answer:
tia_tia [17]3 years ago
3 0

Answer:

a = 1 , b = 0 and c = 5

Step-by-step explanation:

The given matrix are,

[2  1   0]   X 1    -1    2     =   [a    b   c]

                  -1    -2   1

                   0     1    1

a = (2*1) + (1*-1) +(0*0) = 2 -1 + 0 = 1

b = (2*-1) + (1*-2) +(0*1) =-2 -2 + 0 = 0

c = (2*2) + (1*1) +(0*1) = 4 +1 + 0 = 5

Therefore the values of a,b, and c are

a= 1 , b = 0 and c = 5

What is the image point of (1,-1)(1,−1) after a translation left 4 units and down 5 units?
DENIUS [597]

Answer:

The new point would be (-3,-6)

Step-by-step explanation:

To solve this it is nice to graph the first point at (1,-1). Then move the point left 4 units, making x -3. and then 5 units down, which would make y -6.

Answer:

<h3>Q1</h3>

The graph of y = f(x), has vertex at (1, -2)

<u>The vertex of a function f(x - 3) is going to be:</u>

  • (1 - 3, -2) = (-2, -2)
<h3>Q2</h3>
  • <em>The graph of y = f(x) has the line x = 5 as an axis of symmetry. The graph also passes through the point (8,-7). Find another point that must lie on the graph of y = f(x).</em>

The axis of symmetry is at the same distance from the symmetric points.

x = 5 is a vertical line. The point (8, -7) is 3 units to the right. So the mirror point will be 3 units to the left and have same y-coordinate: x = 5 - 3 = 2

The point is (2, -7)

<h3>Q3</h3>

The graph in blue is the translation of the red to the left by 2 units.

<u>So the equation is:</u>

  • y = f(x + 2)
<h3>Q4</h3>

y = h(x) is graphed

  • h(7) = 5
  • h(h(7)) = h(5) = -1
<h3>Q5</h3>

The graph of the function y = u(x) given

This is a odd function.

The coordinates of u(x) and u(-x) add to zero because u(-x) = -u(x)

<u>Therefore:</u>

  • u(-2.72) + u(-0.81) + u(0.81) + u(2.72) =
  • [u(-2.72) + u(2.72)] + [u(-0.81) + u(0.81)] =
  • 0 + 0 = 0
