Step-by-step explanation:

Answer:

The graph of the system in the attached figure

Step-by-step explanation:

we have

isolate the variable y

----> equation A

This is the equation of a vertical parabola open down (because the leading coefficient is negative)

The vertex represent a maximum

the vertex is the point (0,2)

---> equation B

This is the equation of a circle centered  at (0,0) with radius 3 units

The solution of the system of equations is the intersection points both graphs

using a graphing tool

The solutions are the points (-2.05,-2.19) and (2.05,-2.19)

see the attached figure

Answer:

It's C!

Just got it right :>

Answer:

X-4

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable

Answer:

DCB = 84

Step-by-step explanation:

Here, we want to calculate the value of the angle

To do this, we use an important parallelogram angle property

The adjacent sides are supplementary, meaning they add up to 180

We have this as;

180-96 = 84 degrees

Answer:

1920 toys

Step-by-step explanation:

Area of new toy chest :

Area = Length * width

Area = 3 feets * 2 feets

Area of new toy chest = 6 ft²

If ;

1 square foot requires 320 toys

6 ft² = (320 * 6) = 1920 toys

Answer:

y= -0.5 x +3

Step-by-step explanation:

at x=0 , y=3

at x=2 , y=2

y= ax+b

b=3

2=2a+3

2a= -1

a= - 0.5

then

y= -0.5 x +3

Answer:

13

Step-by-step explanation:

a^2+b^2=c^2

12^2+5^2=c^2

144+25=c^2

169=c^2

c=13

Answer:

13

Step-by-step explanation:

I am a little rusty on this but I think to solve youd do

12^2 which is 144 plus 5^2 which is 25, add together and get 169 and then find that the square root of 169 is 13.

Answer: 4 cells.

Step-by-step explanation:

Answer:

In 24 hours you will have 16777216 cells

Step-by-step explanation:

So if we know that we start of with one cell and each hour each cell keeps on doubling then we can find out how much cell there will be in 24 by doing th following.

1 x 2 = 2 (the number of cells after 1 hour)

2 x 2 = 4 (the number of cells after 2 hours)(in order to obtain this we need to multiply the number of cells from the previous hour by 2, and we do this process repeatedly till we get the number of cell after 24 hours). So techencly the number of cells after 24 hours will be equal to

1 x [tex]2^{24}[/tex]

And so the number of cells after 24 hours will be....

1 x [tex]2^{24}[/tex] = 1 x 16777216 = 16777216

Step-by-step explanation:

bro this is simple pay attention in class

Answer:

Step-by-step explanation:

The quotient of zero and one is 0/1 = 0.

A number times itself is written as n^2, where n is the number.  This is the same as n*n.

Answer:

27

Step-by-step explanation:

i Think all are correct not sure tho

Answer:

See below.

Step-by-step explanation:

Note: I am considering that you are supposed to think of the graph maximum point as P(x, y) = P(0, 25).

It means that the absolute maximum at x = 0, so f(0) = 25.

What is the maximum of this graph and what does it represent?

When the ball is on the ground? No, once the maximum of this graph is 25 feet and the ground is 0 feet, the statement is false.

Where the ball ended? No, the final position is h = 0 feet, not h = 25 feet.

Where the ball started? Yes, the ball was dropped in h = 25 feet.

It represents the highest point on the graph? Yes.

25 feet? Yes.

Answer:

x^2-6x+5

Step-by-step explanation:

To have roots at x=5 and x=1 you need to write is as follows

(x-5)(x-1)

you then need to multiply these two and get

x^2-6x+5

Answer:

its 15

Step-by-step explanation:

Answer:

x = -4

Step-by-step explanation:

[tex]x + 5 = 3x + 13[/tex]

Subtract [tex]3x[/tex] from both sides of the equation. You get:

[tex]-2x + 5 = 13[/tex]

Subtract 5 from both sides:

[tex]-2x = 8[/tex]

[tex]x = -4[/tex]

Answer: The bacony floor is 37 feet above the ground floor.

Step-by-step explanation:

Here, the ground level is marked as 0 feet.

The elevation of the balcony floor is 37 feet.

The elevation of the basement floor is -17 feet.

Since elevations relative to ground level at 0 feet.

i.e. elevation of balcony floor is same as the distance of balcony floor from ground.

That means the bacony floor is 37 feet above the ground floor.

Hence, the bacony floor is 37 feet above the ground floor.

Answer:

108.72

Step-by-step explanation:

72 x 1.51 = 108.72

Answer:

The odd answer

is d

This is because 90 + 48 + c gives us 138

and so its not trye

Answer:

about 2.72 hours

Step-by-step explanation:

set up the equation:

40 + 55h = 190

subtract 40 from both sides

55h = 150

now divide both sides by 55

h =  2.72

Step-by-step explanation:

Answer:

False

Step-by-step explanation:

4x4=16

16x4=64

5*5=25

64+25=89

Therefore the answer is false, because 89 is not equal to 95.

Answer:

false

Step-by-step explanation: you don't really need this part but all you need to know is that it is false :)
