Find the length of x

Mathematics
1 answer:
qaws [65]3 years ago
3 0

Answer:

x = 3

Step-by-step explanation:

Hi there!

<u>1) Prove similarity</u>

The two triangles are similar due to angle-angle similarity. They both have an angle measured 90 degrees and the angles of the two corners that touch are equal, because opposite angles are equal.

<u>2) Solve for x</u>

Now, we can set up a proportion to solve for x:

\frac{x}{4} =\frac{4.5}{6} \\x=\frac{4.5}{6} *4\\x=3

Therefore, x is 3 units long.

I hope this helps!

What is (f - g)(x)?<br> f (x) = 24 – 22 + 9<br> 9(2) = 23 + 3x2 + 12<br><br><br> (f - g)(x) = ???
bija089 [108]

Answer:

(f - g)(x) = x^4 - x^3 - 4x^2 - 3

Step-by-step explanation:

Subtract  g(x)=x^3 + 3x^2 + 12 from f(x)= x^4 - x^2 + 9

First, take the negative of every term (including the label g(x) ) of g(x), obtaining  -g(x) = -x^3 - 3x^2 - 12.

Now combine this result with f(x):

 f(x)= x^4 - 0x^3 - x^2 + 9

-g(x) =       - 1x^3 - 3x^2 - 12

---------------------------------------

(f - g)(x) = x^4 - x^3 - 4x^2 - 3

You need a 65% alcohol solution. On hand, you have a 50 mL of a 30% alcohol mixture. You also have 70% alcohol mixture. How much
DIA [1.3K]

Answer:

  350 mL

Step-by-step explanation:

Let q represent the quantity (in mL) needed of the 70% solution. Then the total amount of mixture will be q+50 milliliters. The total amount of alcohol in the mixture will be ...

  0.70q +0.30(50) = 0.65(50 +q)

  .05q = 17.5 . . . . . . subtract (0.65q +1.50)

  q = 350 . . . . . . . . . divide by 0.05

You will need 350 mL of the 70% solution.
