$0.30 for 1 apple
1 apple = 0.30
2 apples = 0.30 x 2 = 0.60
3 apples = 0.30 x 3 = 0.90
2 apples cost $0.60
the pattern is 0.30n or 0.30 x (number of apple)

For the given functions f and g, complete parts (a)-(h). For parts (a)-(d), also find the domain.
slamgirl [31]

The domain for (a) , (b) , (c) is all set of real numbers , for (d) (x ε R except x = 3/8.

The complete question is

a) (f + g)(x), (b) (f – g)(x), (c) (f × g)(x), (d) (f / g)(x), (e) (f + g)(7), (f) (f - g)(2), (g) (f.g)(3), (h) (f/g)(27)

<h3>What is a Function ?</h3>

A function is the law that defines the relation between independent and a dependent variable.

It is given that

f(x) = 3x+8

g(x) = 8x-3

(a)  (f + g)(x) = 3x+8 +8x-3 = 11x+5

(b)  (f – g)(x) = 3x+8 -8x+3 = -5x +11

(c) (f × g)(x) = (3x+8)(8x-3) = 24x²-9x+64x -24 = 24x² +55x-24

(d)(f / g)(x) = (3x+8)/(8x-3)

(e) (f + g)(7) = 11*7+5 = 77+5 = 82

(f) (f - g)(2)= -5*2 +11 = 1

(g) (f.g)(3) =24*9 +55*3 -24 = 357

(h)  (f/g)(27) = (3x+8)/(8x-3)  = (3 * 27 +8)/(8*27-3) = 89/213

The domain for (a) , (b) , (c) is all set of real numbers , for (d) (x ε R except x = 3/8)

What is 2 plus 2 minus 17
nataly862011 [7]

<em>The result is -13</em>

<h2>Explanation:</h2><h2 />

Here we have the following addition problem:

2+2-17

So let's solve this step by step:

Step 1. Perform two plus two.

2+2=4

So:

2+2-17=4-17

Step 2. Perform the subtraction.

Since the sign (-) accompanies 17 which is greater than 4, then we perform the subtraction and add the sign (-) to the result. So:

2+2-17=4-17=-13

<em>Finally, the result is -13</em>

A water balloon is 5 feet above the ground when Sally launches it into the air. Use the quadratic equation 0 = -t^2 + 4t + 5 to
rodikova [14]

Answer:

t=5\ sec

Step-by-step explanation:

we have

-t^{2} +4t+5=0

Solve the quadratic equation to find the zero's or x-intercepts

Remember that

The x-intercepts are the values of x when the value of y is equal to zero ( water balloon reach the ground)

we know that

The formula to solve a quadratic equation of the form ax^{2} +bx+c=0 is equal to

x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}

in this problem we have

-t^{2} +4t+5=0

so

a=-1\\b=4\\c=5

substitute in the formula

t=\frac{-4(+/-)\sqrt{4^{2}-4(-1)(5)}} {2(-1)}

t=\frac{-4(+/-)\sqrt{36}} {-2}

t=\frac{-4(+/-)6} {-2}

t=\frac{-4(+)6} {-2}=-1

t=\frac{-4(-)6} {-2}=5

therefore

the solution is t=5\ sec
