Mathematics
1 answer:
Whitepunk [10]4 years ago
4 0

ANSWER

C

E

F

EXPLANATION

The result of the synthetic division is :

3 -1 0

The last number is the remainder which is 0

The first two numbers are the coefficients of the quotient.

Therefore the quotient is 3x -1

Since the remainder is 0, x-4 is a factor of

f(x) = 3 {x}^{2}  - 13x +  4

This also means that:

(3 {x}^{2}  - 13x +  4)  \div (x - 4) = 3x - 1

This again means that x=4 is a root of

f(x) = 3 {x}^{2}  - 13x +  4

The correct choices are C,E and F.

in a certain recipe, 2 1/4 cups of flour are called for to make a cake that serves 6. of mrs. jenkins wants to use the same reci
Phoenix [80]

If in a certain recipe, a cake serving 6 persons require 2(\frac{1}{2} ) cups of flour and Mrs. Jenkins wants to use the same recipe to make a cake for 8, then she will need to use 3(\frac{1}{3}) cups of flour.


As per the question statement, 2(\frac{1}{2} ) cups of flour are required to bake a cake that serves 6. Mrs. Jenkins wants to use the same recipe to bake a cake for 8.

We have to calculate the number of cups of flours she will need to bake her desired cake as per the same recipe.

To solve this question, we will simply use the unitary method, i.e.,

A cake serving 6 required 2(\frac{1}{2} )=\frac{5}{2} cups of flour in its preparation, then,

A cake serving 1 person will require \frac{\frac{5}{2} }{6} =\frac{5}{12} cups of flour, and finally,

A cake serving 1 person will require (\frac{5}{12} *8)=\frac{10}{3}=3(\frac{1}{3}) cups of flour.

Hence, Mrs. Jenkins wants to use the same recipe to make a cake for 8, then she will need to use 3(\frac{1}{3}) cups of flour.

  • Unitary Method: In Mathematics, the unitary method is a problem-solving technique where, we first find the value of a single unit, and then calculate the necessary value by multiplying that single unit value.

Add 5/9+7/9 . Simplify the answer and write a mixed number
Step2247 [10]

Hello there!

First you had to solving by the fractions parts.

\frac{5}{9}+\frac{7}{9}=\frac{12}{9}

Then you reducing by the fraction parts of 12/9.

\frac{12}{9}=\frac{4}{3}

And finally, you simplify by the fraction parts of 4/3.

\frac{4}{3}=1 \frac{1}{3}

Solution by Formulas

Applying the fractions formula for addiction.

\frac{(5*9)+(7*9)}{9*9}

\frac{45+63}{81}

=\frac{108}{81}

Simplifying 108/81 and the answer is

=1 \frac{1}{3}

Hope this helps!

Thank you for posting your question at here on Brainly.
