What are the real zeros of the function g(x) = x3 + 2x2 − x − 2?
Nat2105 [25]
Upon a slight rearrangement this problem gets a lot simpler to see.

x^3-x+2x^2-2=0  now factor 1st and 2nd pair of terms...

x(x^2-1)+2(x^2-1)=0

(x+2)(x^2-1)=0  now the second factor is a "difference of square" of the form:

(a^2-b^2) which always factors to (a+b)(a-b), in this case:

(x+2)(x+1)(x-1)=0

So g(x) has three real zero when x={-2, -1, 1}

If f(x)= -3x-5 and g(x)= 4x-2 find (f+g)(x)
juin [17]

Known :

f(x) = -3x - 5

g(x) = 4x - 2

Asked :

(f+g)(x) = ...?

Answer :

(f+g)(x) = (-3x - 5) + (4x - 2)

= (-3x + 4x) + (-5 - 2)

= x + (-7)

= <u>x </u><u>-</u><u> </u><u>7</u>

So, the value of (f+g)(x) is x - 7

The table below shows a pattern in the cost of renting a car based on the number of days rented. Car Rentals Number of Days (d)
andrezito [222]

The linear equation that describes the pattern in the cost of renting a car is given by:

  • D. c = 34d + 25

<h3>What is a linear function? </h3>

A linear function is modeled by:

y(x) = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0.

In this problem:

  • For each day, the cost of renting a car increases by 34, hence, the slope is of 34, and the equation is:

c(d) = 34d + b

When d = 4, c = 161, and this is used to find b.

c(d) = 34d + b

161 = 34(4) + b

b = 25

Hence, the equation is c = 34d + 25, and option D is correct.

A survey of voters explored the relationship between the ages of voters and wether or not they support building skateboard ramps
Novosadov [1.4K]

Answer:

(a)12%

(b)20%

(c)49%

Step-by-step explanation:

(a)In the age group 58 and above:

  • Number in favor of building the skateboard ramps=6
  • Number opposed to building the skateboard ramps=44
  • Total = 50

Percentage of those in favor = \frac{6}{50}X100 =12\%

(b)In the age group 18-37

  • Number in favor of building the skateboard ramps=40
  • Number opposed to building the skateboard ramps=10
  • Total = 50

Percentage of those opposed to it = \frac{10}{50}X100 =20\%

(c)

  • Total Number of those in favor of building the skateboard ramps=73
  • Total Number opposed to building the skateboard ramps=77
  • Total = 150

Percentage of those in favour = \frac{73}{150}X100 =48.67 \approx 49\%
