Write the solution as an ordered pair (x,y)​
garik1379 [7]

Answer:

(-2, -3)

Step-by-step explanation:

2x + 1 = 3x + 3

minus 3 from both sides

2x - 2  = 3x

minus 2x from both sides

-2 = x

then plug in -2 for x

y = 2(-2) + 1

y = -4 + 1

y = -3

(-2, -3).

I need help!!! please help me out as quick as possible
Alenkasestr [34]

Answer:

D) 262,144

Step-by-step explanation:

The given sequence is given explicitly as:

A_n =  {4}^{n - 1}

We want to find the tenth term of this sequence.

We substitute n=10 to get:

A_ {10}=  {4}^{10 - 1}

Simplify the exponent

A_ {10}=  {4}^{9}

Simplify the power

A_ {10}=  262144

Therefore the 10th term is 262,144

A cone has the diameter of 15 inches and is 27 inches tall what is the volume for the cone?
suter [353]

Answer:

the volume of a cone = 1589.625feet³

Step-by-step explanation:

given that the diameter of the cone = 15inches

radius = 15inches/2 = 7.5inches

height of the cone = 27 inches

volume of the cone = ?

recall that

the  formulae for finding the volume of a cone is given to be

= 1/3πr²h

the volume of a cone = πr² h/3

the volume of a cone = 3.14  × ( 7.5)² × 27/3

the volume of a cone = (3.14 x  56.25 x27)/3

the volume of a cone = 4768.875/3

the volume of a cone = 1589.625feet³
