What are zeroes of f(x) =x^2-x-2

1 answer:

6 0

You have to factor this...
So you have started with this...

x²-x-2=0
If you factor this you will get

(x+1)(x-2)=0

This gives you two solutions...
x=-1, x=2
Hope this helps! Give me a five-rate and a thanks!

The base of the right prism is a rhombus with the side 7 cm. The altitude of the prism is h=13 cm. Find the lateral area of the

Art [367]

Answer:The lateral area is $364\ cm^{2}$

Step-by-step explanation:

we know that

The lateral area of the right prism is equal to

$LA=Ph$

where

P is the perimeter of the base

H is the height of the prism

Find the perimeter of the base P

$P=4(7)=28\ cm$ ----> the rhombus has four equal sides

$h=13\ cm$

substitute

$LA=28(13)=364\ cm^{2}$

In a given year, the population of Metro City is 7420, and the population is decreasing by 152 people per year. The population o

Anit [1.1K]

Answer:

The correct option is D.

Step-by-step explanation:

Let x denote the years.

The information provided is:

The population of Metro City is 7420.
The population is decreasing by 152 people per year.
The population of Smallville is consistently 1200 less than half of Metro City.

From the provided data derive the equation for the population of Smallville x years after as follows:

$Y = [\frac{1}{2}\cdot (7420-152x)]-1200$

The population of Smallville is 2282 after x years.

Compute the value of x as follows:

$2282= [\frac{1}{2}\cdot (7420-152x)]-1200$

$\frac{7420-152x}{2}=2282+1200\\\\7420-152x=3482\times 2\\\\152x=7420-6964\\\\152x=456\\\\x=3$

Thus, the time it will take for Smallville's population to reach 2282 is 3 years.

The correct option is D.
