1. If x=3-√3, prove that x² +36 x² = x²

valentina_108 [34]

Answer:

we get $x^2=12-6\sqrt{3}$

Step-by-step explanation:

We are given: $x=3-\sqrt{3}$

We need to find $x^2$

Note: Since question is not clear, I am assuming that we need to find $x^2$

Solving:

$x=3-\sqrt{3} \\Taking \ square \ on \ both \ sides\\x^2=(3-\sqrt{3})^2\\$

We know that $(a-b)^2= a^2-2ab+b^2$

Using formula and simplifying

$x^2=(3)^2-2(3)(\sqrt{3})+(\sqrt{3})^2\\x^2=9-6\sqrt{3} +3\\x^2=12-6\sqrt{3} \\$

So, we get $x^2=12-6\sqrt{3}$

Allie fires a rocket from ground level. The height of the rocket is given by the formula h= 260t - 16t^2 (-16t squared), where t

8_murik_8 [283]

Answer:

The rocket would be in the air for 8.125 seconds after launch.

Step-by-step explanation:

Given that the height of the rocket, h = 260t - 16 $t^{2}$ .

To determine how long the rocket would be in the air, differentiate h totally with respect to t.

So that, total derivative of h is given as;

$\frac{dh}{dt}$ = $\frac{d(260t-16t^{2}) }{dt}$

0 = 260 - 16 x 2t

= 260 - 32t

0 = 260 - 32t

32t = 260

t = $\frac{260}{32}$

= 8.125

t= 8.125 seconds

The rocket would be in the air for 8.125 seconds after launch.

Help thanksSSSSSSSSSS

Setler79 [48]

Answer:

$\boxed{\sf{x=24}}$

Step-by-step explanation:

GIVEN:

To find the missing number in the proportion, you have to isolate it the term of x from one side of the equation.

$\sf{\dfrac{8}{7}=\dfrac{x}{21} }$

First, thing you do is switch sides.

$\sf{\dfrac{x}{21}=\dfrac{8}{7} }$

Multiply by 21 from both sides.

$\Longrightarrow: \sf{\dfrac{21x}{21}=\dfrac{8*21}{7} }$

Solve.

Multiply the numbers from left to right.

Use the order of operations.

PEMDAS stands for:

Parentheses
Exponents
Multiply
Divide
Add
Subtract

$\Longrightarrow: \sf{\dfrac{8*21}{7}=\dfrac{168}{7}=24 }$

$\Longrightarrow: \boxed{\sf{x=24}}$

Therefore, the final answer is x=24.

I hope this helps. Let me know if you have any questions.
