Q4. The dimensions of a rectangular sheet of metal are 9.96m by 5.08 m. Find

Vesnalui [34]

Answer:

a) 30m

b) 50.6m²

Step-by-step explanation:

Perimeter = 2(length + width)

= 2(9.96 + 5.08)

= 30.08 m

Area = length × width

9.96 × 5.08

50.5968 m²

Which of the following statements are true of the parabola shown?

Vesna [10]

True statements are:

It has a directrix of x = - 4.
It has a focus at (4, 0).

Step-by-step explanation:

We have the following statements to check on whether it's right or wrong:

1. It has a directrix of x = -4:

According to figure , parabola directrix is at -4 i.e. at x = -4 , Therefore this statement is true!

2. It opens to the left:

In figure, Parabola opens to right not left , Therefore this statement is wrong!

3. It has a vertex at the origin:

Vertex of Parabola is at what points not shown in figure. Therefore this statement cannot be confirmed as true.

4. The axis of symmetry is the y-axis:

Axis of symmetry for above parabola is x-axis as it cuts parabola into two equal halves , y-axis doesn't do this ! Therefore this statement is wrong!

5. It has a focus at (4, 0):

Parabola focus is at $F(4,0)$ on x-axis . And so, Therefore this statement is true!

123,456 is not divisible by which of the following numbers? 3,4,5,6

xxMikexx [17]

The answer is 5 because for it to be divisible by 5 the number needs to end in 0 or 5.
Also 3 goes into that number 41152
4=30864
6= 20576
5= 24691.2
because of the .2 at the end it is not divisible.

so the answer is 5
