Ganezh [65]3 years ago
5 0

Answer:

3) 0.14

5) 2/5

Step-by-step explanation:

3) Ok, so, the equation for number 3 would be 2.24/16, which would be 0.14.

5) Reducing fractions is simplifying them, so divide 40 and 100 by 10 each, which gets 4/10. then, divide each by 2 to get 2/5, which is the most it could be reduced.

What is the length of the missing leg? If necessary, round to the nearest tenth.
KengaRu [80]

<u>Answer:</u>

  • a = 3.5

<u>Step-by-step explanation:</u>

<u>Let's find 'a' using Pythagoras theorem.</u>

  • => 4² = 2² + a²
  • => 16 = 4 + a²
  • => 12 = a²
  • => a = √12
  • => a = √2 x 2 x 3
  • => a = 2√3
  • => a = 2 x √3
  • => a = 2 x 1.732
  • => a = 3.464 = 3.5 (Estimated)

The difference between 48 and 13 algebra numeral expression.
Sphinxa [80]

Numerical expressions contain numbers, while algebraic expressions contain variables and numbers.

<u>Numerical Expression</u>

"Difference" indicates that we'll be subtracting 13 from 48.

48 - 13 = 35

<u>Algebraic Expression</u>

Variables represent the unknown number, in this case the difference between 48 and 13. Let d represent the difference between the two.

48 - 13 = d

35 = d

Given f(x) = 2x² + 4 and g(x) = 3x – 1 ……<br> What is (fg)(x)? <br><br> Show your work.
Lelu [443]

Answer:

(fg)(x) = 6x³ - 2x² + 12x - 4

Step-by-step explanation:

( f g ) ( x ) = f ( x ) * g ( x )

f(x) = 2x² + 4

g(x) = 3x – 1

( f g ) ( x ) = (2x² + 4) (3x – 1)

               = 6x³ - 2x² + 12x - 4
