What is the perimeter of ADC?

9.5 cm, 7.5 cm, 8.5 cm, 5.5 cm

Answer : The perimeter of ADC is, 9.5 cm

Step-by-step explanation :

Perimeter : It is the distance around 2-dimensional shape.

As we know that ADC is a triangle.

Given:

Side AC = 3.5 cm

Side CD = 3 cm

Side AD = 3 cm

Perimeter of triangle ADC = Side AC + Side CD + Side AD

Perimeter of triangle ADC = 3.5 cm + 3 cm + 3 cm

Perimeter of triangle ADC = 9.5 cm

Therefore, the perimeter of ADC is, 9.5 cm

When dividing the polynomial using synthetic division, which of the following setup boxes would be used?

Galina-37 [17]

The setup boxes in the synthetic division are (b)

<h3>How to determine the setup boxes?</h3>

The dividend is given as:

x^3 + 4x^2 + x - 6

The divisor is given as:

x - 2

Set the divisor to 0

x - 2 = 0

Solve for x

x = 2

Remove the variables in the dividend

1 + 4 + 1 - 6

Remove the arithmetic signs

1 4 1 - 6

So, the setup is:

2 | 1 4 1 - 6

Hence, the setup boxes are (b)

Answer:

x = 2 1/4 or 2.25

Step-by-step explanation:

to start we can make an equation

9lbs = 4x

divide by 4

9/4 = x

x = 2.25 or 2 1/4

How to find the area of a sector with a sector angle of 72 degrees and a radius of 14 cm

skad [1K]

Answer:

Exact area: 39.2π cm²

Approximate area: 123.2 cm²

Step-by-step explanation:

The area of a circle is πr².

A full circle can be thought of as a sector of a circle with 360° of central angle. For a sector of a circle with a central angle of n°, multiply the area of the circle by the fraction n°/360°.

The formula for the area of a sector of circle with central angle n° and radius r is

A = (n°)/(360°) × πr²

Here we have n = 72; r = 14 cm

A = (n°)/(360°) × πr²

A = (72°)/(360°) × π × (14 cm)²

A = 39.2π cm² = 123.2 cm²
