Sena determines the remainder of 4x32−14x16+2x3−8x−1, using the remainder theorem. How does she proceed to the correct answer? D
Flauer [41]
Answer: x = 1 and -16

Explanation:

(4x^32 - 14x^16 + 2x^3 - 8)/x - 1

x - 1 = 0
x = 1

f(x) = 4x^32 - 14x^16 + 2x^3 - 8
f(1) = 4(1)^32 - 14(1)^16 + 2(1)^3 - 8
f(1) = 4 - 14 + 2 - 8
f(1) = -10 - 6
f(1) = -16

Therefore, the remainder is -16

Martin is considering the expressions 1/2(7x + 48) and -[1/2x - 3]+ 4(x + 5). He wants to know if one expression is greater than
pentagon [3]
Part A
 The first thing we must do for this case is to rewrite both expressions.
 We have then:
 1/2 (7x + 48) = (7/2) x + 24
 - [1 / 2x - 3] + 4 (x + 5) = - (1/2) x + 3 + 4x + 20 = (7/2) x + 23
 Answer: 
 We note that the first expression is greater than the second for all values of x. 
 Part B:
 A new expression that is greater than both written expressions is:
 (7/2) x + 25
 For all values of x, this expression is always greater.
 Answer:
 (7/2) x + 25

The density of silver is 10.5 g/cm. Find the volume of a silver bar if it’s mass is 950 g.
denis-greek [22]

Answer: The volume is 90.47 cm^{3}

Step-by-step explanation:

1. To solve this problem you need to use the formula for calculate the density, which is shown below:

d=\frac{m}{V}

Where m is the mass and V is the volume.

2. You must solve for the volume, as following:

V=\frac{m}{d}

3. Now, you must substitute the values of the mas and the density, which are given in the problem. Therefore, you have:

V=\frac{950g}{0.5g/cm^{3}}\\V=90.47cm^{3}
