If f(x) = 2x2 – 3x + 4, then f(x + 3) is equal to
If function f(x) = 2x2 – 3x + 4, then f(x + 3) is equal to f(x+3)= 2x^2 +9x +13.
Degree of polynomial is two so it will have only two solution
f(a)=0 if x=a
or
f(b)=0 if x=b
so put X=x+3
we will get
2[x+3]^2 - 3[x+3] + 4 = 2x^2 +9x +13
so if f(x+3)= 2x^2 +9x +13
The highest degree of a polynomial's monomials with non-zero coefficients is referred to as the polynomial's degree in mathematics. A term's degree is a non-negative integer and is calculated by adding the exponents of all the variables that occur in it.
The highest exponent of a polynomial's variable is referred to as the polynomial's degree. • A polynomial of degree zero is a constant polynomial. Zero polynomial is the name given to the constant polynomial f(x) = 0.

13.) An electrician has a piece of wire that is 3 feet long (36 inches). She needs a piece that is exactly 31.05 inches to fit perfectly in the outlet. How much wire will she have left over? *
O she needs to buy more baseboard, she doesn't have enough
O 4.95 inches
O 28.05 inches
O5.05 inches
Answer: 4.95 inches
Subtract: 36 - 31.05 = 4.95
Step-by-step explanation:
Whoever created this question hasn't done much real electrical work!
An outlet (also known as a receptacle) usually requires about 4 to 6 inches of wire within the junction box to make the connections, depending on what else may be connected in the box. We don't have to measure to 0.05 of an inch. The insulation may have to be stripped precisely to 3/8, 1/2 or 5/8 inch for connections.
The electrician used 3 feet of cable between junction boxes, and had 8 ¹/₂ inches pulled through the junction box. She needed 4 inches to connect the receptacle. How much the excess did she have to cut off?
Math questions should be realistic.

Answer:
Arithmeticcommon difference = 7Step-by-step explanation:
First differences are ...
-38 -(-45) = 7
-31 -(-38) = 7
-24 -(-31) = 7
The first differences are constant, so this is an arithmetic sequence with a common difference of 7.

Answer:
2/3
Step-by-step explanation:
To add fractions with different denominators, change the denominator to the least common multiple of the denominators.
The denominators here are 6, 3, and 6. The least common multiple of these three numbers is 6. Now, convert each of the fractions into fractions with a denominator of 6, specifically only 1/3.
1/6+2/6+1/6
Now add up the numerators,
1/6+2/6+1/6 = 4/6
Simplify.
4/6 = 2/3

Answer:

Step-by-step explanation:
The right triangle is isosceles, so x = 45° and tan(x) = 1.
__
You can determine tan(x) either from your knowledge of trig function values, or from the fact that the two legs of the triangle are of equal length. The tangent is the ratio of the opposite leg to the adjacent one. When those legs are the same, the ratio is 1.
