The length of a rectangle is 11cm more than the width. The perimeter is 90cm. Find the length and width of the rectangle.

nadya68 [22]

Answer:

Length=22.5cm, Breadth=11.5cm

Step-by-step explanation:

Let length be l and width be w.

w+22=l

w+w+w+22+w+22=90

4w=90-22-22

=46

w=46 divided by 4

=11.5

l=11.5+11

=22.5

Hence,

Length of rectangle=22.5cm

Breadth of rectangle=11.5cm

Step-by-step explanation:

Question 46.

$(2\sqrt{5}-\sqrt{2} )^2=(2\sqrt{5})^2-2*2\sqrt{5}*\sqrt{2} +(\sqrt{2})^2 } =4*5-4*\sqrt{2*5} +2=\\=20-4\sqrt{10}+2=22-4\sqrt{10}.$

Answer: E. None of these.

Question 47.

$\frac{4\sqrt{5} }{\sqrt{3} } =\frac{4*\sqrt{5}*\sqrt{3} }{\sqrt{3} *\sqrt{3} } =\frac{4*\sqrt{5*3} }{3}=\frac{4\sqrt{15} }{3} .$

Answer: E. None of these.

1. Describe the transformations necessary to transform the graph of

lana66690 [7]

Answer:

- The function $f(x)$ must be shifted right 1 unit.

- The function $f(x)$ must be shifted up 4 units.

- The function $f(x)$ must be stretched vertically by a factor of 3.

Step-by-step explanation:

There are some transformations for a function f(x):

If $f(x)+k$ , then the function is shifted up "k" units.

If $f(x)-k$ , then the function is shifted down "k" units.

If $f(x+k)$ , then the function is shifted left "k" units.

If $f(x-k)$ , then the function is shifted right "k" units.

If $bf(x)$ and $b>1$ , then the function is stretched vertically by a factor of "b".

If $bf(x)$ and $0$ , then the function is compressed vertically by a factor of "b".

In this case we have the following parent function $f(x)$ :

$f(x)=x^2$

And the function $g(x)$ :

$g(x) = 3(x - 1)^2 + 4$

Based on the explained before, we can describe the transformations necessary to transform the graph of $f(x)$ to the graph of $g(x)$ :

- The function $f(x)$ must be shifted right 1 unit.

- The function $f(x)$ must be shifted up 4 units.

- The function $f(x)$ must be stretched vertically by a factor of 3.

What is the difference between the solution of parallel lines and the solution of same/coinciding lines?

motikmotik

The solution of parallel lines will have the same slope but different y-intercepts. The solution of same/coinciding lines will have the same slope and y-intercept.
