Y = $3\sqrt[3]{3}$

81 is the same as 3 x 3 x 3 x 3. Therefore we can take out three of the four 3s and leave one inside the cube root radical.

(PLSSSS HELP) Determine which three out of the six points shown below are a solution to the equation x-3y=22 Plot the three poin

algol [13]

Answer:

$(-2,8)$ $(7,5)$ $(1,7)$

Step-by-step explanation:

Given

$x + 3y = 22$

Solving (a): The possible coordinates

We have:

$(x,y) = (-2,8)$

This gives:

$x + 3y = 22 \to -2 + 3 * 8$

$x + 3y = 22 \to -2 + 24$

$x + 3y = 22 \to 22$

(-2,8) is a point on the grid

$(x,y) = (7,5)$

This gives:

$x + 3y = 22 \to 7 + 3 * 5$

$x + 3y = 22 \to 7 + 15$

$x + 3y = 22 \to 22$

(7,5) is a point on the grid

$(x,y) = (-5,5)$

This gives:

$x + 3y = 22 \to -5 + 3 * 5$

$x + 3y = 22 \to -5 + 15$

$x + 3y = 22 \to 10$

(-5,5) is a not point on the grid

$(x,y) = (1,3)$

This gives:

$x + 3y = 22 \to 1 + 3 * 3$

$x + 3y = 22 \to 1 + 9$

$x + 3y = 22 \to 10$

(1,3) is a not point on the grid

$(x,y) = (1,7)$

This gives:

$x + 3y = 22 \to 1 + 3 * 7$

$x + 3y = 22 \to 1 + 21$

$x + 3y = 22 \to 22$

(1,7) is a point on the grid

So, we plot the following on the grid

$(-2,8)$ $(7,5)$ $(1,7)$

a total of 4 freinds ate lunch at a cafe. they decided to split the bill wvenly. the total bill was $17.84. how much was each pe

ivann1987 [24]

So that would be the total bill divided by 4
17.84/4=16/4+1/4+0.84/4=4+0.25+0.21=4.46

each person's share was $4.46

A baseball is thrown upward and its height after t seconds can be described by formula h(t)=−16t2+50t+5. Find the maximum height

asambeis [7]

h(t) = -16t² + 50t + 5

The maximum height is the y vertex of this parabola.

Vertex = (-b/2a, -Δ/4a)

The y vertex is -Δ/4a

So,

The maxium height is -Δ/4a

Δ = b² - 4.a.c

Δ = 50² - 4.(-16).5

Δ = 2500 + 320

Δ = 2820

H = -2820/4.(-16)

H = -2820/-64

H = 2820/64

H = 44.0625

So, the maxium height the ball will reach is 44.0625
