Using scalar multiplication, it is found that 5u = <10,20>.

<h3>What is scalar multiplication?</h3>
  • It is when a vector is multiplied by a constant, and it means that each term of the vector is multiplied by the constant.

In this problem, the vector is:

u = <2,4>

Since each term is multiplied by 5:

5u = <5 x 2, 5 x 4> = <10,20>.

4+4x+x^2 = y Given x = 3
stira [4]

Answer:

y=25

Step-by-step explanation:

y=4+4x+x^2

x=3

y=4+4(3)+(3)^2

y=4+12+(3)^2

y=4+12+(3x3)

y=4+12+(9)

y=16+9

y=25

Gina looks at the architectural plan of a four-walled room in which the walls meet each other at right angles. The length of one
masha68 [24]
If the shape of the room is a square, then the square root of the sum of the squares of the the two adjacent sides will give the diagonal.

i.e.

\sqrt{17^2+17^2} = \sqrt{2(17^2)}  \\  \\ = \sqrt{2(289)} = \sqrt{578} =24.04

Since the square root of the sum of the squares of the the two adjacent sides is 24.04 and not 18.79, therefore, the shape of the room is not a square.

stepan [7]

Answer:

- 25 and - 623

Step-by-step explanation:

Using the term to term rule with u₀ = - 3 , then

(a)

u₁ = u₀³ + 2 = (- 3)³ + 2 = - 27 + 2 = - 25

(b)

u₂ = u₁³ + 2 = (- 25)³ + 2 = - 625 + 2 = - 623

Drag the tiles to the correct boxes to complete the pairs. Solve the inequalities for x, and match each solution to its number l
svetlana [45]

in the figure, the first number line goes with x \leq5

the second number line goes with x \geq 5

the third number line goes with x > 5

the fourth number line goes with x < 5

Two less than 3/2 of a number x is  no more than 5/2 is shown as:

3/2 x- 2 \leq 5 1/2

3/2 x \leq 11/2 + 2

3/2 x \leq 15/2

3x \leq 15

x \leq 5

The sum of two times a number (x) and -2 is at least 8 is shown as :

2x+(-2) \geq 8

2x - 2 \geq 8

2x \geq 8+2

2x \geq 10

x \geq 5

Seven subtracted from 4 times a number (x) is more than 13 is shown as

4x -7 > 13

4x > 13+7

4x > 20

x > 20 ÷ 4

x > 5

Four added to 3 times a number (x) is less than 19 is shown as

3x + 4 < 19

3x < 19-4

3x < 15

x < 15 ÷ 3

x< 5
