The length a rectangle is 2 cm grater than its width .the area is the rectangle is 80 cm square what is the width of the rectang
maw [93]

Answer:

Step-by-step explanation:

If breadth =x

length =x+2

Area =length *breadth

Area =x(x+2)=80

X^2+2x-80=0

X^2 +10x - 8x - 80=0

X(x+10)- 8(x+10)=0

(X-8)(x+10)=0

X=8 or x=-10

X=8(since breadth cannot be a negative value x cannot be negative)

Let f(x)= 3x – 6 and g(x) = x –2. Find f/g and its domain.
Maksim231197 [3]
<span>Given :
f(x)= 3 x – 6
and
g(x) = x –2

f(x)/g(x) = (</span>3 <span>x – 6 </span>)/(x - 2)
simplifying
f(x)/g(x) = 3( x – 2 )/(x - 2<span>)

Consider the function f(x)=-3x^2 +7x -k. [3 Marks] a) For what values of k will the function have no zeros? b) For what values o
Anna35 [415]

Answer: a) k >4.08

b) k = 4.08

c) k<4.08

Step-by-step explanation:

Since we have given that

f(x)=-3x^2+7x-k

a) For what values of k will the function have no zeros?

It mean it has no real zeroes i.e. Discriminant < 0

As we know that

D=b^2-4ac

Here, a =-3

b = 7

c = -k

So, it becomes,

D

b) For what values of k will the function have one zero?

It means it has one real root i.e equal roots.

So, in this case, D = 0

So, it becomes,

D=b^2-4ac=0\\\\D=7^2-4\times -3\times -k=0\\\\49-12k=0\\\\49=12k\\\\k=\dfrac{49}{12}\\\\k=4.08

c) For what values of k will the function have two zeros?

It means it has two real roots.

In this case, D>0

So, it becomes,

D=7^2-4\times -3\times -k>0\\\\49-12k>0\\\\-12k>-49\\\\12k

Hence, a) k >4.08

b) k = 4.08

c) k<4.08

2. What is the area of the figure below? (2 point)
Vitek1552 [10]

Answer:

63 m^2

Step-by-step explanation:

The figure appears to be a parallelogram.

area of parallelogram = base * height

Use the 14-m side as the base. Then the height is the perpendicular distance between the two opposite 14-m sides, so the height is 4.5 m.

area = base * height

area = 14 m * 4.5 m

area = 63 m^2

P.S. The choices are given in square meters (m^2), which is a unit of area, not in meter times square root of 2 "m sqrt(2)."
