Forensic specialists can estimate the height of a deceased person from the lengths of the person's bones. These lengths are subs
Lera25 [3.4K]

Answer:

130.2845\leq h\leq 137.7245

Step-by-step explanation:

Given an inequality that relates the height h, in centimeters, of an adult female and the length f, in centimeters, of her femur by the equation

|h - (2.47f + 54.10)| \leq  3.72

If an adult female measures her femur as 32.25 centimeters, we can determine the possible range of her height by plugging f = 32.25cm into the modelled equation as shown:

|h - (2.47(32.25) + 54.10)| \leq  3.72\\|h - (79.9045 + 54.10)| \leq  3.72\\|h - (134.0045)| \leq  3.72\\

If the modulus function is positive then:

h - 134.0045 \leq  3.72\\h \leq 3.71+134.0045\\h\leq 137.7245

If the modulus function is negative then:

-(h - 134.0045) \leq  3.72\\-h+134.0045 \leq 3.72\\-h\leq 3.72-134.0045\\-h\leq -130.2845\\

multiply through by -1

-(-h)\geq  -(-130.2845)\\h\geq 130.2845\\130.2845\leq h

combining the resulting inequalities, the estimate of the possible range of heights will be 130.2845\leq h\leq 137.7245

Boden conjectures that in a right triangle, the sine of one acute angle is always equal
ruslelena [56]

Answer:

Boden's conjecture is correct

Step-by-step explanation:

we know that

If two angles are complementary, the cofunction identities state that the sine of one equals the cosine of the other and vice versa.

A right triangle, has two acute angles.

The two acute angles are complementary

so

In any right triangle, the sine of one acute angle is equal to the cosine of the other acute angle

therefore

Boden's conjecture is correct

A cone has a diameter of 4 centimeters and a height that is 6 times the diameter. Using 3.14 for pi, which of the following can
Verizon [17]

Answer:

Option B is correct that is volume of the cone is one over three (3.14)(2cm)^2(24).

Step-by-step explanation:

Given: Diameter of the Cone , d = 4 cm

           Height of the cone , h = 6 × d = 6 × 4 = 24 cm

To find: Volume of cone.

radius of cone , r = \frac{d}{2}=\frac{4}{2}=2\:cm

Volume of the cone is given by the following formula,

Volume=\frac{1}{3}\pi r^2h

Volume=\frac{1}{3}(3.14)(2)^2(24)

Volume=\frac{1}{3}(3.14)(4)(24)

Therefore, Option B is correct that is volume of the cone is one over three (3.14)(2cm)^2(24).
