A portion of the graph of f(x) = −x2 − 2x + 8 is shown. Which of the following describes all solutions for f(x)?
Naily [24]

Answer:

(x,-x^2-2x+8) where −5 ≤ x ≤ 3

Step-by-step explanation:

The given function is f(x)=-x^2-2x+8.

We want to select the option that describes all the solutions to the parabola.

The domain of the parabola is −5 ≤ x ≤ 3.

This means that  any x=a on −5 ≤ x ≤ 3 that satisfies (a,f(a)), is a solution.

This can be rewritten as (a,-a^2-2a+8)

Therefore for x belonging to −5 ≤ x ≤ 3, all solutions are given by:

(x,-x^2-2x+8) where −5 ≤ x ≤ 3.

SVEN [57.7K]

Answer: Domain of the function represented in the graph is given by he inequality . 2 <_ x _< 10  

Step-by-step explanation:

we know that

Observing the graph

The domain is the quantity of yellow paint in millimeters

The domain is the interval -----> [2,10]

All real numbers greater than or equal to 2 and less than or equal to 10

therefore 2 <_ x _< 10

1.) Number of Total Shirts = 220

In Figure 1, Red boxes represent "<span>short sleeve shirts" which is 7 in number whereas Blue boxes represent "long sleeve shirts".

1 box contains = 220/10 = 22 shirts 

Number of short sleeves = 22 * 7 = 154

<span>In short, Your Final Answer would be: 154 

</span></span>2.) Number of Total Subscribers = 260

In Figure 1, Red boxes represent "<span>regular subscribers" which is 10 in number whereas Blue boxes represent "premium subscribers".

1 box contains = 260/13 = 20 subscribers. 

Regular subscribers = 20 * 10 = 200 

<span>In short, Your Final Answer would be: 200
</span></span>
3.) Number of Total People = 360

In Figure 1, Red boxes represent "<span>Males" which is 3 in number whereas Blue boxes represent "females".

1 box contains = 360/12 = 30 people

Number of males: = 30 * 3 = 90

<span>In short, Your Final Answer would be: 90

Hope this helps!

Which of the following expressions has a value between 5 and 6.
Airida [17]
So listen to this logic
lets say you have 3 numbers, m,a,x where they are all positivie
m>a>x
therefor
m^2>a>2>x^2
if m and a and x are square roots, therefor we can reverse the square root
confusing sorry

square 5 and 6
5^2=25
6^2=36

the number betwe 25 and 36

that would be 32

answer is √32

goes like this
5^2<32<6^2
sqrt both sides
5<√32<6

answer is √32
