So the equation is 5-x3
x^3=x*x*x
so you have x=-2
That means y=5-(-2*-2*-2)
y=5-(-8) which gives y=13
Do this for every x and get the y

Answer:

y's go

13, 6, 5, 4, -3

Step-by-step explanation:

well so you have the equation y = 5 - x^3

you are given the x for all of them

y = 5 - (-2)^3

5 - (-8) = 13

y = 5 - 0^3

5 - 0 = 5

y = 5 - 1^3

5 - 1 = 4

y = 5 - 2^3

5 - 8 = -3

Can someone help me!!! been stuck on this for a while!!

Natali5045456 [20]

Answer:

Volume: Option A - Around 85.33 (in^3)

Step-by-step explanation:

Let us take a look at the problem. Here we are given the circumference of the bowling ball, provided it is in the shape of a sphere.

Our first step can be to note the formula of circumference, applicable to both a sphere and a circle:

C = 2 * π * r - Where r = radius

Now let us substitute the known value of the circumference as to solve for r, or the radius:

(8π) = 2πr

r = 8π/2π

r = 4

Now take a look at the spherical formula for volume of a sphere:

V = 4/3 * π * r^3 - Where r is yet again the radius

Let us substitute the known value of the radius as to solve for the volume, or in other words to solve for the answer:

V = 4/3 * π * (4)^3

V = 4/3 * π * 64

V = 256/3 * π

V = (Around) 85.33π (in)^3

*Don't forget the units

Which shapes are quadrilaterals?

lubasha [3.4K]

Hey there! I'm happy to help!

A quadrilateral is any polygon (enclosed shape) with four sides. Let's see what each of these shapes are.

Scalene right triangle - the prefix tri- means three (tricycle, tripod, triple, etc.), and all triangles have three sides, so this is not a quadrilateral.
Obtuse scalene triangle - once again a triangle, so not a quadrilateral.
Isosceles right triangle - would you look at that, another triangle! Not a quadrilateral.
Hexagon - a hexagon is a six-sided polygon (hex=six), so this is not a quadrilateral.
Pentagon - a pentagon is a five-sided polygon (pent=five, like Pentatonix!). Not a quadrilateral
Right trapezoid - a trapezoid is a quadrilateral with at least one pair of parallel sides!
Venn diagram - a Venn diagram is a compare and contrast chart made of two overlapping circles (ZERO sides), so this is not a quadrilateral.

So, the only shape on your list that is a quadrilateral is 6. right trapezoid.

Have a wonderful day! :D

If cot 0= 4/3, find csc 0

miskamm [114]

Answer:

5/3

Step-by-step explanation:

Trigonometric ratio

Cot θ = Adjacent side/Opposite side

It is given that,

Cot θ = 4/3

Adjacent side = 4

Opposite side = 3

Csc θ = Hypotenuse/Opposite side

To find the Hypotenuse

Hypotenuse² = Opposite side² + Adjacent side ² = 3²+ 4²

Hypotenuse = √(3²+ 4²) = 5

To find Csc θ

Csc θ = Hypotenuse/Opposite side = 5/3

How is an equation like an expression? How is it different?

morpeh [17]

Answer:

See explanation.

Step-by-step explanation:

An expression is a set of terms that are combined using addition, subtraction, multiplication, or division. The following are examples of expressions:

$2x-1$

$5y+8$

$2$

Note: expressions do not equal anything.

In contrast, equations are expressions that equal at least one term. The following are examples of equations:

$2y-4=26$

$4x-4=0$

$x=10$

$y=x+2$

Note: equations do equal a term, as shown in the examples.

Find two numbers that have a sum of -2 and a product of -48 (please show work if possible)

andreev551 [17]

Answer: -8 and 6

Step-by-step explanation:

factors of 48: 1,2,4,6,8,12,24,48

1 x 48

2 x 24

4 x 12

6 x 8

for a negative product, one of the factors must be negative and the other positive.

for two number to have a sum of -2, the greater number must be the negative number, and both numbers should have be two values apart (ex. 6 and 8, 3 and 5, 12 and 14, etc.). In this case, 8 would have to be negative whereas 6 will be left positive.

and then we check:

-8 x 6 = 48

-8 + 6 = -2
