I need to know how to simplify using conjugate

liubo4ka [24]

$\frac{4}{2 \sqrt{7}+ \sqrt{6} }$
Multiply denominator and numerator of fraction by conjugate (2√7 -6)
= $\frac{4(2 \sqrt{7})(- \sqrt{6}) }{(2 \sqrt{7} + \sqrt{6})(2 \sqrt{7} - \sqrt{6} ) }$
Expand using distributive property
= $\frac{8 \sqrt{7}- 4 \sqrt{6} }{28-2 \sqrt{42}+2 \sqrt{42} -6 }$
Collect like terms to simplify
= $\frac{8 \sqrt{7}-4 \sqrt{6} }{22}$

Please help me with this

juin [17]

Answer:

10π (31.415926)

√101(10.0498756)

9.92749...

0.99853...

Step-by-step explanation:

For 10π, we can simplify π into 3.14 for an approximate amount. 3.14*10=31.4

For the square root of ten, we can estimate it's between 10 and 11 since 10 squared is 100 and 11 squared is 121.

How can i find The function of f(x) = 150 (1.3)^t

natka813 [3]

Answer:

See below.

Step-by-step explanation:

In comments, you said you wanted it graphed.

If it says f(x) on the left side, the equation should have an 'x' on the right side, so something is fishy here.

But, in an effort to try and help you ....

With the data you have given, I would graph it just like y = 150 (1.3)^x

You can pick various values for x, like -3,-2,-1,0,1,2,3 and see what y is for each one, then plot the points on graph paper.

If x = 0, y= 150(1.3)^0 = 150(1) = 150 because anything to power zero is 1

If x = -1, y= 150(1.3)^(-1) = 150(1/1.3) ≈ 132.7

If x = +1, y= 150(1.3)^(1) = 150(1.3) = 195

And so on.

I did the graph on DESMOS and it has a very large scale.

An airplane is flying from New York City to Los Angeles. The distance it travels in miles, d is 0.15 per second of time, t.

garik1379 [7]

Here the function given by

f(d)=0.15t

Now

f(1):-

$\\ \sf\longmapsto f(1)=0.15(1)=0.15m$

$\\ \sf\longmapsto f(2)=0.15(2)=0.3m$
