Volume of the pyramid = (1/3) * base area * height
Base area = 230² = 52,900 m²
Volume of the pyramid = (1/3) * 52,900 * 138 = 2,433,400 m³

If f(x) = 2x - 6 and g(x) = 3x + 9, find (f + g)(x).

Yuliya22 [10]

Answer:

$\large\boxed{(f+g)(x)=5x+3}$

Step-by-step explanation:

$(f+g)(x)=f(x)+g(x)\\\\f(x)=2x-6,\ g(x)=3x+9\\\\\text{Substitute:}\\\\(f+g)(x)=(2x-6)+(3x+9)\\\\=2x-6+3x+9\qquad\text{combine like terms}\\\\=(2x+3x)+(-6+9)\\\\=5x+3$

Help me with inverse table and start x with -2. Show work please

ANTONII [103]

Answer:

The answer to your question is below

Step-by-step explanation:

Function f(x) = (2 - x)²

Inverse y = (2 - x)²

x = (2 - y)²

$\sqrt{x} = 2 - y$

y = $2 - \sqrt{x}$

$f^{-1}(x) = 2 - \sqrt{x}$

Function Inverse

x f(x) x $f^{-1}( x)$

. I take a sample of 322 Wooster students and find that their mean checking account balance is $232 with a standard deviation of

KengaRu [80]

Answer: The required confidence interval is (220.873,243.127).

Step-by-step explanation:

Since we have given that

Sample = n = 322

Mean = $232

Standard deviation= $36

At 94% confidence interval,

z = 1.88

So, the confidence interval for average would be

$\bar{x}\pm z\dfrac{\sigma}{\sqrt{n}}\\\\=232\pm 1.88\times \dfrac{36}{\sqrt{37}}\\\\=232\pm 11.127\\\\=(232-11.127,232+11.127)\\\\=(220.873,243.127)$

Hence, the required confidence interval is (220.873,243.127).
