A Pizza Slice Is In The Shape Of A Circular Sector OAB, With The Central Angle 0 = 50 Deg And A Radius

Answers

Answer 1

Answer:

The perimeter of the pizza slice is 20.1 cm

Step-by-step explanation:

Perimeter of a Sector of a Circle

The arc length of a sector of a circle of radius r and angle θ is given by:

L = rθ

The angle must be expressed in radians.

The total perimeter of the circular sector, including the two radii, is:

P = rθ + 2r

The pizza slice has a radius of r=7 cm and a central angle of θ=50°

Converting to radians:

[tex]\theta=50*\frac{\pi}{180}=\frac{5\pi}{18}[/tex]

The perimeter is:

[tex]P = 7*\frac{5\pi}{18} + 2*7[/tex]

Calculating:

P = 20.1 cm

The perimeter of the pizza slice is 20.1 cm

Answer:

x=7

Step-by-step explanation:

I believe we are solving for x. In that case, let us start by moving 1 to the other side.

[tex]\frac{4(x+3)}{5} = 8[/tex]

Now, we want to get rid of that denominator of 5. Let us multiply both sides by 5:

[tex]4(x+3)=40[/tex]

Now, we may divide both sides by 4 to get rid of the coefficiant:

[tex]x+3=10[/tex]

When we subtract both sides by 3, we get

x=7

b = y-intercept (but we dont see it here, it goes through the point 0)

To find slope do rise over run ( y/x)

r/r = 3/1 = 3

The slope is 3

If and , what is the domain of g(x) ÷ f(x)?

A.


B.


C.


D.

Answers

g(x)/f(x) will be simplified to (x+3)(x-3)/2-x^1/2,
which will give you [0,4) ∪(4, ∞).
Choice B

The domain of g(x)  ÷ f(x) is [0, 2) U (2, ∞). Option D

How to determine the domain

We must take into account the restrictions on both g(x) and f(x) in order to determine the domain of the function h(x) = g(x)/f(x).

There are no restrictions on x for g(x) = x² - 9. This is to avoid a zero denominator.

The square root function needs the parameter (x) to be non-negative (x 0) for f(x) =[tex]2 - x^(^1^/^2^)[/tex] to work. We also exclude out x = 2 because the denominator cannot be zero.

Combining these restrictions, the intersection of the g(x) and f(x) domains yields the domain of h(x), which is:

Domain of h(x) in interval notation is [0, 2) U (2, ∞).

A right triangle has side lengths of 3cm, 4cm, and 5cm. What is the sine of the angle opposite the side of length 4cm

Answers

In a right triangle, the sine of the angle opposite the side of length 4 cm is 0.8 cm.

In a right triangle, the sine of an angle is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse.

The angle opposite the side of length 4 cm can be calculated as:

The hypotenuse is the side of length 5 cm.

The calculation of the sine of the angle can be calculated using the formula:

[tex]Sine = \dfrac{Opposite}{hypotenuse}[/tex]

Substitute the value in the given formula.

[tex]Sine(A) = \dfrac{4}{5}[/tex]

Sine(A) = 0.8

So, the sine of the angle opposite the side of length 4 cm is 0.8 cm.
