Solve t^4-2t^3+24t^2=0​
AlexFokin [52]

Answer:

t=0, 6, -4

Step-by-step explanation:

first, you can factor out t² of the equation

t²(t²-2t+24)=0, then factor the trinomial

t²(t-6)(t+4)=0, now set each factor equal to zero

t²=0, so t = 0

t-6=0, so t = 6

t+4=0, so t = -4

If you graph it, you can also see the answers.

The points (2,4) and (-2,-4) are plotted on a coordinate plane the equation is y = a * x what is A?
laila [671]

A equals to 2.

<u>Step-by-step explanation:</u>

y = mx + c is the equation of the line and m is the slope and c is the y- intercept.

In the given equation, y = ax , a is the slope.

Slope A can be found by means of the formula, and using the points (2,4) and (-2-4)

slope, A = (y₂ -y₁) /  (x₂-x₁)

Plugin the values as,

A = (-4-4) / (-2-2) =  (-8) / (-4) = 2

So the value of A is 2.

Helpppp quick pleaseeeeee

Answer:

3 and 4

Step-by-step explanation:

It would be 3 and 4.

What times what gives 10?

Well

1x1=1

2x2 =4

3x3=9

4x4=16

So it would be 3 but that doesn't give you 10. It would go into the decimal places and would be greater than 3.

It would be less than 4 because 4x4 gives 16.

Thus the 2 whole numbers in between are 3 and 4.
