BARSIC [14]

To answer this, you will first need to simply the expressions.

$4\sqrt{27} = 12\sqrt{3}$

$6\sqrt{75} = 30\sqrt{3}$

Now with the expressions simplified, you'll add the two together getting $42\sqrt{3}$

Answer:

Step-by-step explanation:

You know that angle Y is a right angle because XY is the radius and YZ is a tangent to the circle. So, you can use the pythagorean theorem to find the third side:

XY^2+4^2=5^2

XY^2+16=25

XY^2=9

XY=3

F(x) = -4x2 – 7x + 4<br> Find f(-7)

notka56 [123]

Answer:

Step-by-step explanation:

$f(x) = - 4 {x}^{2} - 7x + 4$

To find f(-7) , substitute the value of x that's - 7 into f(x). That is for every x in f(x) replace it with - 7

We have

$f( - 7) = - 4 ({ - 7})^{2} - 7( -7 ) + 4 \\ = 4(49) + 49 + 4 \\ = 196 + 53 \: \: \: \: \: \: \: \: \: \: \:$

We have the final answer as

Hope this helps you
