Answer: 5

Step-by-step explanation:

The formula for calculating common difference is given by :

$t_{2}$ - $t_{1}$ = $t_{3}$ - $t_{2}$ = $t_{4}$ - $t_{3}$

Where $t_{1},t_{2}$ are the terms given .

from the sequence given :

$t_{1}$ = 105

$t_{2}$ = 110

$t_{3}$ = 115

$t_{4}$ = 120

Therefore : common difference will be

110 - 105 = 5

115 - 110 = 5

120 - 115 = 5

Therefore , 5 is the common difference

What is the area of the shaded portion of the circle?

SOVA2 [1]

Answer:

The first option is the correct one, the area of the shaded portion of the circle is

[/tex](5 \pi -11.6)ft^2[/tex]

Step-by-step explanation:

Let us first consider the triangle + the shadow.

The full area of the circle is the radius squared times pi, so

A= $(5 ft)^2 \cdot \pi \\25 ft^2 \cdot \pi$

Since $\frac{72^{\circ}}{360^{\circ}}=\frac{1}{5}$ , the area of the triangle + the shaded area is one fifth of the area of the whole circle, thus

$A_1=\frac{1}{5}25 ft^2 \cdot \pi\\ =5 ft^2 \cdot \pi$

If we want to know the area of the shaded part of the circle, we must subtract the area of the triangle from $A_1$ .

The area of the triangle is given by

$A_{triangle}=\frac{1}{2}\cdot (2.9+2.9)ft \cdot 4 ft\\= 11.6 ft^2$

Thus the area of the shaded portion of the circle is

$A_1-A_{triangle}=5 \pi ft^2-11.6ft^2\\= (5 \pi -11.6)ft^2$

Which statement is true about the radical expression square root of 25

Lena [83]

Answer:

Step-by-step explanation:

The square Root of 25 in its simplest form means to get the number 25 inside the radical √ as low as possible.

25 is a perfect square, which means that you can simply calculate the square Root of 25 to get the answer. 5 times 5 equals 25. Thus, the square Root of 25 in simplest radical form is = 5
