Oksana_A [137]3 years ago
5 0

Answer:

-\frac{1}{28}

Step-by-step explanation:

-1/2 ÷ 2(9+3)-4 - 3/4(8)

-0.5 ÷ 2(12)-4 - 3/4(8)

-0.5 ÷ 2(12)-4 - 6

-0.5 ÷ 24-4 - 6

-0.5 ÷ 14 = -\frac{1}{28}

In the given diagram, the value of the dashed side of rhombus OABC is 5

<h3>Distance between two points </h3>

From the question, we are to determine the length of the dashed line (OA), in rhombus OABC

In the diagram, we can observe that the length of OA is the distance between point A and the origin (O).

Using the formula for calculating distance between two points,

d =√[(x₂-x₁)² + (y₂-y₁)²]

In the diagram,

The coordinate of the origin is (0, 0)

The coordinate of point A is (3, 4)

Thus,

x₁ = 0

x₂ = 3

y₁ = 0

y₂ = 4

Putting the parameters into the formula, we get

OA =√[(3-0)² + (4-0)²]

OA =√(3² + 4²)

OA =√(9+16)

∴ OA =√25

OA = 5

Hence, in the given diagram, the value of the dashed side of rhombus OABC is 5

Write down the fifth term of the sequence that has its nth term:
Mice21 [21]

Answer:

a) 34

b) 30

Step-by-step explanation:

so the nth term is just the position on the term, so if u want to find the 5th term you just have to substitute 5 in for n and solve!

a) 6n + 4

= 6(5) + 4

= 30 + 4

= 34          --> the 5th term for a sequence defined by 6n+4 is 34

b) n^2 + 5

= (5)^2 + 5

= 25 + 5

= 30           --> the 5th term for a sequence defined by n^2 + 5 is 30

hope this helps!
