Work out 1/2 x 7 giving your answer as a mixed number
irga5000 [103]

Answer:

4\frac{1}{2}

Step-by-step explanation:

This question is basically saying: what is half of 7, or what is 7 divided by 2?

Based on this, it can be written both of the ways as:

»»  \frac{1}{2} of 7  <u>OR</u>  7 ÷ 2

So, just solve using either one and you’ll get 4.5 or 4\frac{1}{2}. But since the question wants the answer to be a mixed number, then choose 4\frac{1}{2}.

Hope this helps! :)

The price of commodity a is 4500 and increases at the rate of $6 every three months. Commodity b costs $5400 and increases at ra
ivanzaharov [21]
Let x be the months and y be the cost.

Rate of increase of commodity A = 6/3 = $2 per month
Equation:
y = 2x + 4500

Rate of increase of commodity B = 2/4 = $0.5 per month
Equation:
y = 0.5x + 5400

Equating the costs,
2x + 4500 = 0.5x + 5400
1.5x = 900
x = 600 months
x = 600 / 12 = 50 years

If f(1) = 0, what are all the roots of the function f (x) = x cubed 3 x squared minus x minus 3? Use the Remainder Theorem. X =
LiRa [457]

All the roots of the provided function If f(1) is equal to the zero are -3, -1 and 1.

<h3>What is polynomial?</h3>

Polynomial equations is the expression in which the highest power of the unknown variable is n (n is real number).

The function given in the problem is,

f(x)=x^3+3x^2-x-3

If f(1) = 0

f(1)=(1)^3+3(1)^2-(1)-3\\f(1)=1+3-1-3\\f(1)=0

Thus, (x-1) is one of the factor of polynomial. Equate the polynomial equal to the zero, to find other roots as,'

x^3+3x^2-x-3=0\\x^2(x+3)-1(x+3)=0\\(x+3)(x^2-1)\\(x+3)(x+1)(x-1)=0

Equate all the groups to zero to find the roots as,

x+3=0, x=-3\\x+1=0, x=-1\\x-1=0, x=1

Hence, all the roots of the provided function If f(1) is equal to the zero are -3, -1 and 1.
