A sheet of plywood was made by gluing 7 sheets of wood together.
LuckyWell [14K]
We can use the equation y=2(0.0625)+5(0.125), y being the thickness of the plywood.
I got 5(0.125) because two sheets of the 7 were already used, meaning there are 5 sheets of plywood left over.
y=0.125+0.625
y=0.75
Therefore, the plywood is 0.75 inches thick.

Help please and thank you: The graph of f x = x2 − 2x − 3 is shown. Which of these describes the effect changing f x to f −2x wi
Lemur [1.5K]

Answer:

Option (C).

Step-by-step explanation:

Graphed function is,

f(x) = x² - 2x - 3

     = x² - 2x + 1 - 1 - 3

     = (x² - 2x + 1) - 4

     = (x - 1)² - 4

f(-2x) = (-2x)² - 2(-2x) - 3

        = 4x² + 4x - 3

        = 4(x² + x) - 3

        = 4[x² + 2(0.5)x + (0.5)²- (0.5)²] -3

        = 4(x + 0.5)² - 1 - 3

        = 4(x + 0.5)² - 4

        = 4[(x - 1) + 1.5]² - 4

Therefore, parent function 'f' will be a horizontal shrink by 4 units and  shifted 1.5 units to the left.

Option (C) will be the answer.

0.5 meters in 50 centimeters because there are 100 centimeters in 1 meter. so 100/50 is 50 which is a half or 0.5.

630 centimeters in 6.3 meters. 6.3*100=630
