F(x)=x^2-1 <br> G(x)=x-1 <br> find (f+g)(10).
WARRIOR [948]
<h2>Adding Functions</h2><h3>Answer:</h3>

(f +g)(10) = 108

<h3>Step-by-step explanation:</h3>

Before we can solve for (f +g)(10), we need to know how (f +g)(x) is defined.

(f +g)(x) = f(x) +g(x) \\ (f +g)(x) = (x^2 -1) +(x -1) \\ (f +g)(x) = x^2 -1 +x -1 \\ (f +g)(x) = x^2 +x -2

We can now solve for (f +g)(10):

(f +g)(10) = (10)^2 +(10) -2 \\ (f +g)(10) = 100 +10 -2 \\ (f +g)(10) = 108

3. Find x.<br> 8x - 37<br> 5x + 17<br><br><br> I really need help with this
sveticcg [70]

Answer: here is your steps Simplifying

8x + -37 = 5x + 17

Reorder the terms:

-37 + 8x = 5x + 17

Reorder the terms:

-37 + 8x = 17 + 5x

Solving

-37 + 8x = 17 + 5x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-5x' to each side of the equation.

-37 + 8x + -5x = 17 + 5x + -5x

Combine like terms: 8x + -5x = 3x

-37 + 3x = 17 + 5x + -5x

Combine like terms: 5x + -5x = 0

-37 + 3x = 17 + 0

-37 + 3x = 17

Add '37' to each side of the equation.

-37 + 37 + 3x = 17 + 37

Combine like terms: -37 + 37 = 0

0 + 3x = 17 + 37

3x = 17 + 37

Combine like terms: 17 + 37 = 54

3x = 54

Divide each side by '3'.

x = 18

Simplifying

x = 18

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!
coldgirl [10]

Answer:

z = -0.4.

Step-by-step explanation:

Here's the formula for finding the z-score (a.k.a. standardized normal variable) of one measurement x of a normal random variable X \sim N(\mu,\; \sigma^{2}):

\displaystyle z = \frac{x-\mu}{\sigma},

where

  • z is the z-score of this measurement,
  • x is the value of this measurement,
  • \mu is the mean of the random normal variable, and
  • \sigma is the standard deviation (the square root of variance) of the random normal variable.

Let the length of a trout in this lake be X inches.

X \sim N(30, \; 4.5^{2}).

  • \mu = 30, and
  • \sigma = 4.5.

For this measurement, x = 28.2. Apply the formula to get the z-score:

\displaystyle z = \frac{x - \mu}{\sigma} = \frac{28.2 - 30}{4.5} = -0.4.

Triangle DEF is circumscribed about circle R. Points S, T and U are points of tangency where SD = 4 m and UF = 7 m. What is the
Svetllana [295]
The measure off DF is 11.

In a circle inscribed within a triangle, the distance from each vertex of the triangle to the two nearest touchpoints (points of tangency on the circle) are equal.  Since SD=4, DT=4 as well.  Since UF=7, then FT=7.  

DF=DT+TF=4+7=11.

The Recreation Center has an L-shaped pool. One pool is 8 meters by 6 meters. The other part is 12 meters by 6 meters. The whole
defon

Answer:

480m³

Step-by-step explanation:

The entire pool have the same depth which is 4metres

Since the pool is L shaped, we will find the volume of each part and add them together to get the volume of the entire pool.

Using the formula for calculating volume of a rectangular box

V = lwh

L is the length

w is the width

h is he height

For the first pool.

Length = 8m

Width = 6m

Height = 4m (depth)

Volume = 8×6×4

Volume = 192m³

For the other pool.

Length = 12m

Width = 6m

Height = 4m (depth)

Volume = 12×6×4

Volume = 288m³

Volume of the entire pool = 192+288 = 480m³
