Answer:

Step-by-step explanation:

This is a special right triangle: 5, 12, 13

Or you can solve using the Pythagorean Theorem (a^2+b^2=c^)

--> 13^2-12^2=b^2

-->169-144=b^2

-->25=b^2

b=5

Answer:

solution

here

hypotenuse (h)=13

perpendicular(p)=12

now,

h^2=p^2+b^2

13^2=12^2+b^2

169=144+b^2

169-144=b^2

b^2=25

b=5

The perimeter of the scalene triangle is 54.6 cm.

olchik [2.2K]

Answer:

b = 45.9 - c

Step-by-step explanation:

A scalene triangle has non of its sides equal.

Perimeter = 54.6

side a = 8.7 cm

side b = unknown

side c = unknown

Perimeter of a shape is sum of all its sides.

Perimeter = a + b + c

54.6 = 8.7 + b + c

Making b the subject

b = 54.6 - 8.7 - c

b = 45.9 - c

The value of b is (45.9 - c)

The average income, I, in dollars, of a lawyer with an age of x years is modeled with the following function: I = -425x^2 + 45,5

lord [1]

We are given

The average income, I, in dollars is

$I=-425x^2+45500x-650000$

(a)

now, we are given

average income is $275000

so, $I=275000$

now, we can set them equal

and then we can solve for x

$275000=-425x^2+45500x-650000$

$-425x^2+45500x-925000=0$

we will have to use quadratic formula

$x=\frac{-45500+\sqrt{45500^2-4\left(-425\right)\left(-925000\right)}}{2\left(-425\right)}:\quad \frac{-\sqrt{45500^2-1572500000}+45500}{850}$

$x=\frac{-45500-\sqrt{45500^2-4\left(-425\right)\left(-925000\right)}}{2\left(-425\right)}:\quad \frac{\sqrt{45500^2-1572500000}+45500}{850}$

we get

$x=27.28199$

$x=79.776$

we need to find youngest age

It means that we need to choose smallest value

so,

$x=27$ ............Answer

(b)

we are given

x=40

so, we can plug it and find I

$I=-425(40)^2+45500(40)-650000$

$I=490000$ ..............Answer
