Answer:

15 \geqslant  - 3x  \\  \frac{15}{3}  \geqslant  - x \\ 5 \geqslant  - x \\  - 5 \leqslant x

\frac{2}{5}x \geqslant  - 2 \\ x  \geqslant  - 2 \times  \frac{5}{2}   \\ x \geqslant  - 5

What is the length of the unknown
AVprozaik [17]
The answer is A.

Explanation:

Since this is a right triangle you can use The formula: leg squared plus leg squared = hypotenuse squared

So lets square the hypotenuse and first leg
And you get 85 hypotenuse and 49 leg

So just subtract 49 from 85 to get the other leg squares

You get 36 so now just square root it

Square root of 36 is 6

So the best answer is 6

Hope this helps some.

What is the equation of the graph below? A graph shows a parabola that opens up with a vertex at negative three comma negative o
Tomtit [17]

Answer:

y=(x+3)^2-1\\y=x^2+6x+8

Step-by-step explanation:

Given:

Vertex of the parabola is, (h,k)=(-3,-1)

Equation of the parabola in vertex form is given as:

y=(x-h)^2+k

Plug in h=-3,k=-1. This gives,

y=(x-(-3))^2+(-1)\\y=(x+3)^2-1

Therefore, the equation of the given graph is

y=(x+3)^2-1\\y=x^2+6x+8.

In this triangle, what is the value of x?
pochemuha
To solve for x we can use trigonometry since the triangle above is right triangle.
In this problem, it would be the easiest to use the TOA ratio which means the tangent of 62 equals x/40. To get x alone, we can multiply both sides by 40 leaving us with:
x = tan. 62 x 40
x = 1.88072646535 x 40
x = <span>75.229058614

Final Answer: x is around 75 yards</span>

Paul bags of raisin bars in a pan shaped like a rectangle or prism the volume of the pan is 252 in.³ the length of the pants 12
e-lub [12.9K]

Answer:

The height of the pan is 2 inches.

Step-by-step explanation:

Given : Paul bags of raisin bars in a pan shaped like a rectangle or prism the volume of the pan is 252 in.³ the length of the pants 12 inches and it's with is 10\frac{1}{2} inches.

To find : What is the height of the pan ?

Solution :

The volume of a rectangle or prism is

V=l\times w\times h

Where, l=12 inches is the length

w=10\frac{1}{2} inches is the width

V=252 in.³ is the volume

h is the height

Substitute the value,

252=12\times 10\frac{1}{2}\times h

252=12\times \frac{21}{2}\times h

h=\frac{252\times 2}{12\times 21}

h=2

Therefore, the height of the pan is 2 inches.
