oksano4ka [1.4K]

Answer:

\red{{7}^{15} }

Step-by-step explanation:

We know that,

{x}^{a}  \times  {x}^{b}  =  {x}^{a + b}  \\ ( {x}^{a} ) ^{b}  =  {x}^{ab}

Accordingly,

( {7}^{5} ) ^{3}  \\  {7}^{5 \times 3}  \\  {7}^{15}

Write down the first three terms of the sequence whose nth term is given by 2n-5
likoan [24]

Answer:

- 3, - 1, 1

Step-by-step explanation:

To find the first 3 terms substitute n = 1, 2, 3 into the formula

a₁ = 2(1) - 5 = 2 - 5 = - 3

a₂ = 2(2) - 5 = 4 - 5 = - 1

a₃ = 2(3) - 5 = 6 - 5 = 1

The first 3 terms are - 3, - 1, 1

The lengths of all sides of a triangle are integers when measured in decimeters. One of the sides has length of 1 dm and another
hram777 [196]

Answer:

The perimeter is 7 dm

Step-by-step explanation:

we know that

The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side.

Let

c------> the length of the third side

case a)

1+c>3

c>2 dm

case b)

1+3> c

4 > c

rewrite

c<4 dm

The solution for c is the interval------> (2,4)

therefore

the value of c must be equal to

c=3 dm (because is an integer)

The perimeter is equal to

P=1+3+3=7 dm
