What s the length of the arc for the half circle

Andrej [43]

Answer`Step-by-step explanation:

The length of an arc depends on the radius of a circle and the central angle Θ. We know that for the angle equal to 360 degrees (2π), the arc length is equal to circumference. Hence, as the proportion between angle and arc length is constant, we can say that:

(-6,8); perpendicular to y = -3/2x -1

UNO [17]

Answer:

$y = \frac{2}{3} x + 12$

Step-by-step explanation:

$y = - \frac{3}{2} x - 1$

The gradient of a line is the coefficient of x when the equation of the line is written in the form of y=mx+c.

Thus, gradient of given line= $- \frac{3}{2}$ .

The product of the gradients of perpendicular lines is -1.

(Gradient of line)(-3/2)= -1

Gradient of line

$- 1 \div ( - \frac{3}{2} ) \\ = - 1( - \frac{2}{3} ) \\ = \frac{2}{3}$

Substitute m= $\frac{2}{3}$ into y=mx+c:

$y = \frac{2}{3} x + c$

To find the value of c, substitute a pair of coordinates.

When x= -6, y= 8,

$8 = \frac{2}{3} ( - 6) + c \\ \\ 8 = - 4 + c \\ c = 8 + 4 \\ c = 12$

Thus, the equation of the line is $y = \frac{2}{3} x + 12$ .

One number is three more than a second number. Three times the first is 13 less than 5 times the second.

irakobra [83]

14 and 11

let x be the second number then the first number = x + 3 ( 3 more than second)

Also 3(x + 3) = 5x - 13

3x + 9 = 5x - 13

subtract 3x from both sides

9 = 5x - 3x - 13

9 = 2x - 13

add 13 to both sides

22 = 2x

divide both sides by 2

11 = x → second number

first number = x + 3 = 11 + 3 = 14

Step-by-step explanation:

$13) \: no \: of \: people = 2 \div \frac{1}{8} \\ = 2 \times \frac{8}{1} \\ = 16 \\ \\ 14) \: no \: of \: prizes \: won \: by\:Mallory \\ = \frac{2}{ \cancel3} \times \cancel6 \\ = 2 \times 2 \\ = 4 \\ \\ 15) \: no \: of \: quart \: diced \: tomatoes \\ = 5 \frac{1}{4} \times 1 \frac{2}{3} \\ \\ = \frac{ \cancel{21}}{4} \times \frac{5}{ \cancel3} \\ \\ = \frac{7}{4} \times 5 \\ \\ = \frac{35}{4} \\ \\ = 8 \frac{3}{4} \\ \\ 16) \: no \: of \: blocks = 123 \frac{1}{2} \div 6 \frac{1}{2} \\ \\ = \frac{247}{2} \div \frac{13}{2} \\ \\ = \frac{247}{2} \times \frac{2}{13} \\ \\ \frac{247}{13} \\ \\ = 19$
