Answer:the triangle has (2,) and (0, 4) as its vertices for a maximum area
Step-by-step explanation:let P(x,0) be the x-intercept and Q(0,y) be the y-intercept
label (1,2) as A(1,2)
the slope AP = slope AQ
-2/(x-1) = (2-y)/1
2x - xy - 2 + y = -2
y(1-x) = -2x
y = -2x/(1-x) or 2x/(x-1)
H^2 = x^2 + y^2
= x^2 + ( (2x/(x-1) )^2 --- simplify if needed
(don't know why we are finding the hypotenuse ? )
Area of triangle OPQ
= (1/2)base x height
= (1/2)xy
= (1/2)x(2x/(x-1))
= (1/2) (2x^2/(x-1) )
dA/dx = (1/2) [ (x-1)(4x) - 2x^2(1) ]/(x-1)^2
= (1/2) [ 4x^2 - 4x - 2x^2 ]/(x-1)^2
= 0 for a max of A
2x^2 - 4x = 0
x(2x-4) = 0
x=0 ---- > makes no sense, look at diagram
or
x = 2
then y = 2(2)/(2-1) = 4
the triangle has (2,) and (0, 4) as its vertices for a maximum area
Answer:
Heyyyy
Step-by-step explanation:
4x + (-3) = -11
What is my answer can You please help me
Answer:
-2
Step-by-step explanation:
Let's solve your equation step-by-step
4x−3=−11
Step 1: Add 3 to both sides
4x−3+3=−11+3
4x=−8
Step 2: Divide both sides by 4
4x
4
=
−8
4
x=−2
Answer:
[tex]4x + ( - 3) = - 11 \\ 4x (- 3) = - 11 \\ 4x = - 11 + 3 \\ 4x = - 8 \\ x = \frac{ - 8}{4} \\ x = - 2[/tex]

The length of a picture frame is inches more than the width. For what values of x is the perimeter of the picture frame greater than inches?
9514 1404 393
Answer:
x > 35
Step-by-step explanation:
The perimeter is twice the sum of length and width. You want x such that ...
P > 156
2(x +(x+8)) > 156
4x +16 > 156 . . . . . simplify
x +4 > 39 . . . . . . . . divide by 4
x > 35 . . . . . . . . . . . subtract 4
The perimeter of the frame will be greater than 156 inches for x > 35.
if p q by the consecutive interior angles theorem which angles must be supplementary
Answer:
Angles 3 and 8 are consecutive interior angles
Step-by-step explanation:
Here, we want to use the consecutive interior angles theorem to find the supplementary angles
We start by looking at the transversal line
two angles that are directly above each other on the two lines are consecutive interior angles that are supplementary
We have this two as;
Since it is P and Q that are parallel, it is angles 3 and 8 that are consecutive interior angles

D. 44
Show work, if possible. Thanks❤️
Answer:
I'm doing some of these questions now in my math class. I think it's D) 44 sorry if I'm wrong tho
Answer:
Step-by-step explanation:
Since the hypotenuse is 44 and the two sides are equal to FT we can say
2(FT)^2=44^2
FT^2=968
FT=22(2^(1/2))
So C is the correct answer.
can yall pls help wit this pls asap

Answer: 4955.30
Step-by-step explanation:
F = P (1+i)^n
F = $4000 (1+.055)^4
F = $4955.2986
Which will be 4955.30
Answer:
A. $4955.30
Step-by-step explanation:
Look at the equation
A(t)= P(1+r)^t
In this equation,
A(t) is your amount after a period of time,
P is the initial balance stated in the question (4000)
r is the rate (must be converted to a decimal) as stated in the question (0.055)
t represents the amount of time that has passed (4 years)
Whenever you plug this into the equation, you get
A(t) = 4000(1.055)^4 and this can be plugged into a calculator to get your answer which will be
4955.29 (round up to .3) and your final answer is A. 4995.30
In order to convert from percent to decimal you just need to move the decimal to the left two places
5.5 becomes 0.055 after the decimal is shifted

A recipe for cookies calls for
cups of chocolate chips for every 3 dozen cookies made. How many cups of chocolate chips would be needed for 7 dozen cookies?
A.
B.
C.
D.
For 7 dozens cookies 3 1/2 cups needed.
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
For 3 dozen cookies = 1 1/2 cups = 3/2 cups
For 1 dozen cookies = 3/2 * 1/3 = 1/2 cups needed
So, for 7 dozen cookies = 1/2 * 7
= 3 1/2 cups needed
Hence, for 7 dozens cookies 3 1/2 cups needed.

Answer:
x = 60
Step-by-step explanation:
So, ever triangle, no matter what shape or size, is always going to equal 180 degrees. You start off by trying to find angle L which is 71. The way you find this is you subratch 109 from 180 which ultimately gives you 71.
180 - 109 = 71
After that you have to add what you already have (49 degrees) with what you just found (71 degrees)
49 + 71 = 120
Now that you have 120, you have to again subtract 180 by 120 to get your answer, 60 degrees. And that's it.
180 - 120 = 60
