Answer:

The circumference is 9 or approximately 28.26 inches.

Step-by-step explanation:

To calculate the circumference of a circle, multiply the diameter of the circle with π (pi). The circumference can also be calculated by multiplying 2×radius with pi (π=3.14).

Answer:

The answer is either 56.55in or 28.27

Step-by-step explanation:

This is the formula that I used

C=2πr

Circumference = 2·π·4.5 ≈ 28.27433 or

Circumference = 2·π·9 ≈ 56.54867

The answer can be either one. It depends on if 9 is the radius or the diameter of this circle. If 9 is the radius, then the answer would be 56.55in. If the radius isn't 9 but 9 is the diameter, then your radius would be 4.5 and the answer would be 28.27in.

Hope that helps :)

Write the equation of the line in slope-intercept form.

Butoxors [25]

Equation of the perpendicular
y= 2x+6
slope of the perpendicular = 2

slope of the req. line = -1/2

equation of the req. line
y - y1 = m(x - x1)
y - 2 = -1/2(x + 4)
2(y - 2) = -1(x + 4)
2y - 4 = -x - 4
2y = -x
y = (-1/2)x

this is your req. equation of line.

Answer:

$\displaystyle \boxed{66 \times 7}\:7(60 + 6)$

$\displaystyle \boxed{97 \times 4}\:4(100 - 3)$

$\displaystyle \boxed{8(4 + 2)}\:32 + 16 = 48$

$\displaystyle \boxed{5(9 - 6)}\:(5 \times 9) - (5 \times 6)$

$\displaystyle \boxed{3(4 + 7)}\:(3 \times 4) + (3 \times 7)$

Step-by-step explanation:

According to the Order of Operations [GEMS\BOMDAS\PEMDAS etc.], you evaluate everything in parentheses first before preceding with your Division & Multiplication and Subtraction & Addition. When you do this, you will know exactly which expression corresponds with its Distributive Property expression.

Find the equation of the line with the given slope that passes through the given point. Write the

allsm [11]

Answer:

y + 3 = 2(x + 1)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = 2 and (a, b) = (- 1, - 3), thus

y - (- 3) = 2(x - (- 1)), that is

y + 3 = 2(x + 1)

1. cos B= a/x

x= 11/cos 37°

x= 13.77

2. tan A= a/x

x= 4/tan 41°

x= 4.60

3. sin B = x/c

x= sin 37° × 10.3

x= 6.20

4. tan A= a/b

tan A= 4/13

A= tan-1(0.31)

A= 17°6'10"

5. cos A= b/c

cos A= 12/13

A= cos -¹(0.92)

A= 22°37'12"

6. tan B= a/b

tan B= 3/3

tan B= 1

B= tan‐¹(1)

B= 45°
