A=LW, and we are told that L=W+10

Using L=W+10 in A=LW you have:

A=(W+10)W

A=W^2+10W

W^2+10W=880, we are told that A=880 so

W^2+10W=880  now we can complete the square...

W^2+10W+25=905

(W+5)^2=905

W+5=±√905

W=-5±√905, since W>0

W=-5+√905  and since L=W+10

L=5+√905

W=-5+√905 ft and L=5+√905 ft

If we want an approximation:

W≈25.08 ft and L≈35.08 ft  (both dimensions to the nearest hundredth)

Hello! Hmm. Let’s see. I think it has to be 100x + 60y <= 600. The x variable represents the fast machine suits and the y variable represents the slow machine wet suits. You wrote the greater than or equal to sign, which is not correct. The maximum means no more than, which would mean the less than or equal to sign. The sign you wrote would mean at least that amount or more.

Find the range of the function f(x) = 4x - 7,
ratelena [41]

Answer:

(- 19, - 11, 5, 25)

Step-by-step explanation:

The given function is f(x) = 4x - 7

Now, we have to find the range of the given function for the given domains.

The domains are given as (2 - 5, - 1, 3, 8) i.e. (- 3, - 1, 3, 8).

Therefore, f(- 3) = 4(- 3) - 7 = - 19

f(- 1) = 4(- 1) - 7 = - 11

f(3) = 4(3) - 7 = 5

f(8) = 4(8) - 7 = 25

So, the ranges of the function are (- 19, - 11, 5, 25) (Answer)

Given 3 sides of a triangle - how to tell it right, acute, or obtuse 8,11, 16
user100 [1]
Using Pythagorean theorem, we can justify our answer.
if c^2 = a^2 + b^2 then triangle is right one,
if c^2 > a^2 + b^2 then triangle is obtuse and
if c^2 < a^2 + b^2 then triangle is acute triangle.

Here a=8, b=11 and c=16
Put these values in the equation
16^2 = 8 ^2 + 11^2
256 = 64 +121
256> 185
So here c^2 > a^2 + b^2  Which means triangle is obtuse triangle.

Answer: Obtuse Triangle
