If f(x) = 2x2 – 3x + 4, then f(x + 3) is equal to

Answers

Answer 1

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

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.

C. 2 units
D. 10 units

Answers

The anwser is 14 units

Answer:

D. 10 units

Step-by-step explanation:

Using the distance formula:

d = √(x2 – x1)² + (y2 – y1)²

Plug in the values of the points:

d = √(3 – (-5))² + (-2 – 4)²

d = √(8)² + (-6)²

d = √64 + 36

d = √100

d = 10

9e + 4=5e + 14 + 13e

Answers

Answer:

e = -1

Step-by-step explanation:

1. 9e + 4 = 5e + 14 + 14e

2. 9e = 5e + 10 + 14e

3. 9e = 19e +10

4. -10e = 10

5. e = -1

Hope that helps

Answer:

e - 10

Step-by-step explanation:

1.) We need to manipulate the equation to get e by itself.

2.) To solve the equation, do the following steps;

9e + 4 = −5e + 14 + 13e

9e + 4 = 14 + 8e (Combine like terms)

9e + 4 − 8e = 14 + 8e − 8e (Subtract 8e from each side)

e + 4 = 14 (Combine like terms)

e + 4 - 4 = 14 - 4 (Subtract 4 from each side)

e = 10 (Combine like terms.

3.) Answer: e = 10.

Now lets check our work. To check your work, do the following steps;

9e + 4 = −5e + 14 + 13e

9e + 4 = 14 + 8e

9(10) + 4 = 14 + 8(10)

90 + 4 = 14 + 80

94 = 94

By doing those steps we can confirm the answer, e = 10, is true.

What is Trigonometry?

One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.

We have,

Ryan is 228 feet above the water and the angle of depression to the dolphin is 15.

Using trigonometry

tan 15 = 228/ x

x= 228/ tan 15

x= 228 / 0.26794919243

The ratio of the sides of a triangle is 2:4:9. If the perimeter is 165 inches, what is the length of the longest side?

Answers

Answer:

99inches

Step-by-step explanation:

The ratio of the sides of a triangle =2:4:9.

perimeter = 165 inches,

Total ratio= 2+4+9=15

perimeter = 165

Divide the perimeter by total ratio

165/15=11

Each of the sides

= (2×11) =22

(4×11) =44

now add 12 to both sides: 4x = 192

now divide by 4 on both sides x = 48
