There should have been an attached image.

Area of a circle is can only be computed when the radius or diameter is provided.

Area of a circle = π r²

Based on the image I saw, the radius is 5.6 inches

A = 3.14 * (5.6in)²
A = 3.14 * 31.36 in²
A = 98.47 in² ⇒ CHOICE D. 98.5 square inches.

The sides of a triangle are in the ratio 3 : 4 : 5. What is the length of each side if the perimeter of the triangle is 90 cm
svet-max [94.6K]
The sides of the triangle are 3x, 4x and 5x

3x + 4x + 5x = 90
12x = 90
x = 90/12
x = 7.5

first side = 3x = 3 * 7.5 = 22.5 cm
second side = 4x = 4 * 7.5 = 30 cm
third side = 5x = 5*7.5 = 37.5 cm

A circle has a center at A (4,5), Determine the radius of the circle given two end points of the circle are B (9,5) and C (-1,5)
Anna71 [15]

ANSWER :

The center-radius form of the circle equation is in the format (x – h)2 + (y – k)2 = r2, with the center being at the point (h, k) and the radius being "r". This form of the equation is helpful, since you can easily find the center and the radius.

Find the domain for the rational function f of x equals quantity x end quantity divided by quantity x minus 5 end quantity.
Gennadij [26K]

Answer:

All real numbers except for 5.

Step-by-step explanation:

f(x)=\frac{x}{x-5}

The domain of rational functions is determined by the denominator. The denominator cannot equal zero since if they do, the function will be undefined.

Thus, we need to find the zero(s) of the denominator to determine the domain.

x-5=0

x=5

Therefore, the domain of the rational function is all real numbers except for 5.

In set builder notation, this is:

\{x|x\in \mathbb{R}, x\neq 5\}

I don’t know how to do this. HELP!
Karo-lina-s [1.5K]

Answer:

1/4

Step-by-step explanation:

coins have 2 sides, tails and heads, so for it to land on tails is a 1/2 chance. Dice have 6 sides and 1,3,5 are all odd so its a 3/6 chance. Simplify 3/6 to 1/2 and multiply by 1/2 to get 1/4. im not sure, its my guess.
