Answer:

17.85 in

Step-by-step explanation:

2πr is formula for the circumference but $\frac{1}{2}$ ×π×r is the circumference for the quarter circle.

0.5×π×5=

2.5π≈

7.85

7.85+5+5=17.85 in

Daniel receives a 35% employee discount on all purchases he makes at the store. If he buys his brother a jersey that is regularl

Alona [7]

Answer:

The price to pay is $16.22

Step-by-step explanation:

From the question, the regular price is $24.95

now, there is a discount

So the price to pay is the regular minus the discount

Mathematically, we have this as:

24.95 - 35% of 24.95

= 24.95 - 0.35(24.95)

= $16.2175

This is approximately $16.22

Please can any one please help me with both of these

alexandr402 [8]

Answer:

Question 3: $4x^3+x^2-12x-3$

Question 4: $\frac{1}{2x}, x\neq 0$

Step-by-step explanation:

<u>Question 3</u>

g(x) * h(x) means to multiply both the functions given.

Also note the distributive property:

$(a+b)(n+p)=an+ap+bn+bp$

Now, lets multiply:

$g(x)*h(x)=(4x+1)(x^2-3)\\=(4x)(x^2)-3(4x)+1(x^2)-1(3)\\=4x^3-12x+x^2-3\\=4x^3+x^2-12x-3$

The 2nd answer choice is right

<u>Question 4</u>

$(\frac{f}{g})(x)$ means to divide both the functions and simplify, if possible. Lets do this:

$(\frac{f}{g})(x)=\frac{6x-3}{12x^2-6x}=\frac{3(2x-1)}{6x(2x-1)}=\frac{3}{6x}=\frac{1}{2x}$

This is the correct answer.

The restriction on the domain is any x value that we CANNOT PUT IN THE FUNCTION.

We know we cannot divide by 0, so what makes this fraction division by 0??

If we put x = 0, the function is undefined. So x CANNOT be 0.

Third answer choice is right.
