The threshold weight T, in pounds, for a person is the weight above which the risk of death increases greatly. The threshold weight in pounds for men aged 40 – 49 is related to height h in inches by the function defined by h(T)=(1860.867T)13 What height corresponds to a threshold weight of 200 lb for a 46 yr – old man? Round your answer to the nearest inch and then to the nearest tenth of a foot

Step-by-step explanation:

The equation isn't properly given. Rather, I will do a similar problem available online. The question is:

The threshold weight T for a person is the weight above which the risk of death increases greatly. The threshold weight in pounds for men aged 40 - 49  is related to height h  in inches by the formula

What height corresponds to a threshold weight of 216 Ib for a 43 -year-old man? Round your answer to the nearest inch and then to the nearest tenth of a foot.

Solution:

43 year old man falls into the the age group of 40-49 and thus the formula is shown above.

We want the height "h" corresponding to a weight of 216 pounds. So we plug in 216 into T of the formula and find our answer for h (in inches):

The height is 73.8 inches, nearest inch is 74 inches

74/12 = 6.16 feet, nearest feet is 6 ft

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
