  1. About 127.3(square root of 16,200, or 90√2)  Look at this problem like a right triangle.  Each leg is 90 feet, so the hypotenuse is the square root of 90^2 + 90^2
  2. About 52.3(square root of 2735.64)  Another right triangle problem!  Once again, with Pythagorean theorem (a^2 + b^2 = c^2) You can deduce that 60^2 = 29.4^2 + the width of the TV^2.
  3. About 11.6(Square root of 134.75)Another right triangle problem, you can deduce that 9.5^2 + The pool length^2 = 15^2

Hope it helps <3

(If it does, please give brainliest, only need one more for rank up :) )

Answer:

2. 18\sqrt{5}

3. 52.303...

4. 11.608...

Step-by-step explanation:

2. Using the Pythagorean Theorem, we can see that a^2+b^2=c^2. Therefore, 90^2+90^2=8100+8100=c^2. We know that 8100+8100 is 16200. The square root of 16200  is 90\sqrt{2}.

3. Same as before, we use the Pythagorean Theorem. This time, we're calculating b instead of c. This means we have to do 60^2-29.4^2=b^2, which gives us 3600-864.36, which equals 2735.64. We can put this in decimal form, which would give us 52.303...

4. This one, we do 15^2-9.5^2, which would give us 134.75. Simplifying this would give us 11.608....

Hope this helped! Just remember the Pythagorean Theorem.

The function y = x * ln(x + e) has two distinct x intercepts. One is at x = a and the other is at x = b. The value of a + b is
Snezhnost [94]
As points, x-intercepts take the form (x,0), so to find the intercepts we can set y=0 and solve for x.

x\ln(x+e)=0\implies\begin{cases}x=0\\\ln(x+e)=0\end{cases}

From the first equation alone, we already know that x=0 is a solution, which means one intercept is (0,0).

The second equation gives

\ln(x+e)=0\implies e^{\ln(x+e)}=e^0\implies x+e=1\implies x=1-e

so that the second intercept occurs at (1-e,0).

So if a=0 and b=1-e, we have a+b=1-e, giving C as the answer.

N order to write an expression like (5x + 4)3 in expanded form, it helps to look at (5x + 4) as just one number, n.
Vladimir79 [104]

The expression (5x + 4)^3 in expanded form is 125 x3 + 300 x2 + 240 x + 64.  The expression will have also a root of x = -4/5. This is the form of trinomial expansion and can be  solve by multiplying the the term 3 times.
