The answer sidnetmeza13 is:

because;

When you enter the values for each variable, you get $6^{2} + 6-5-1$ .

Once you start simplifying, you see that 6-5-1 equals 0, so you just need to solve $6^{2}$ , which is 36.

= (4/3) × 3.14 × 6cm × 6cm × 6cm

= 4 × 3.14 × 2cm × 6cm × 6cm

= 904.32 cm³

The Senior class has 350 students. How much is the total bill if the Student government wants to buy each Senior a T-shirt costi

Scilla [17]

To find the cost of Senior T-shirts needed, 
Multiply (the number of students) by (how much each T-shirt costs).
350 × 7.2 = $2520
To find the cost of the yearbooks needed,
Multiply (the number of students) by (how much each yearbook costs).
350 × 24.75 = $8662.5
Now, find the TOTAL money the Student government has to pay.
Add up the two sums.
2520 + 8662.5 = $11182.5

SO, the answer is $11182.5

The Candy Factory sells candy by the pound, charging $1.60 per pound for quantities up to and including 20 pounds. Above 20 poun

rusak2 [61]

Answer:

$k=6$

Step-by-step explanation:

We have been given that the Candy Factory sells candy by the pound, charging $1.60 per pound for quantities up to and including 20 pounds. Above 20 pounds, the Candy Factory charges $1.30 per pound for the entire quantity, plus a quantity surcharge k.

$\left \{ {{p(x)=1.6x, \text{ If }x\leq 20} \atop {p(x)=1.30x+x,\text{ if }x>20}} \right.$

For the price function be to continuous at $x=20$ , the value of both functions at $x=20$ must be equal. Because a function is continuous if the right hand limit is equal to left hand limit.

$1.6(20)=1.3(20)+k$

Let us solve for k.

$32=26+k$

$32-26=26-26+k\\\\6=k$

Therefore, the price function p is continuous at $x=20$ , when k is equal to 6.
