A. 3in, 4in, 5 in
5^2 ?  3^2 + 4^
25   ?  9 + 16
25   =  25
Because the two sides are equal, this is a right triangle.

b. 5in, 6in, 7in
7^2  ?  5^2 + 6^2
49   ?  25 + 36
49   <  61

Because 49 < 61<span>, this is an acute triangle.

c. 8in, 9in, 12in
12^2  ?  8^2 + 9^2
144    ? 64 + 81
144    < 145

Because 144< 145 , this is an acute triangle.

Anestetic [448]
This equals the  the area of white part / area of the entire dartboard

area of the entire board = pi * 6^2 = 36pi

area of white part = 36pi  - 2^2*pi  = 32pi

do required probability = 32pi / 36pi  =  0.889   or 88.9 %   (to nearest tenth)

<h2>Question</h2>

There is a special relationship between the lengths of the legs of a right triangle and the length of its hypotenuse. This relationship is known as the

<h2>Answer</h2>

Pythagorean Theorem.

Step-by-step explanation:

The Pythagorean Theorem states that the square of one leg (a) plus the square of the other leg (b) is equal to the square of the hypotenuse (c). This can be written as A^{2} + B^{2} = C^{2}.

Which point is an x-intercept of the quadratic function f(x) = (x – 4)(x + 2)?
lozanna [386]

The quadratic equation is in factored form, which is f(x) = (x - a)(x - b), where a and b are the x-values for the x-intercepts.

The x-values for the x-intercepts are 4 and -2. We know that the y-value at any x-intercept must be 0 (otherwise it isn't an x-intercept).

Thus, either the points (4,0) or (-2,0) must be your answer (the question is only asking for one x-intercept).

We know that 1 ft = 12 in.
The dimensions of the trunk of a car:
4 ft = 48 in wide, 3 ft = 36 in deep,  2 ft = 24 in tall.
V = 48 * 36 * 24 = 41,472 in³
41,472 in³ ≈ 4 * 10^4 in³
And the volume of the calculator:
V ( calc. ) = 3 * 4 * 12 = 144 in³
Answer:
Desi`s error is D ) The volume of the calculator is not about 60 in³.
