Match each function on the left to all points on the right that would be located on the graph of the function
Answers
By direct evaluation we have found the following results about functions and points:
The points (1, - 3) and (5, 5) are part of the function f(x) = 2 · x - 5.The point (1, 1) is part of the function f(x) = 2 · x² - 8 · x + 7.The point (4, 1) is part of the function f(x) = 2√(x - 4) + 1.What function does a point belong to?Herein we have three functions and four points which has to be checked with respect to each of these functions. A quick approach consists in evaluating each function at every value of x and choose from the outputs.
Case A
f(1) = 2 · 1 - 5
f(1) = - 3
f(4) = 2 · 4 - 5
f(4) = 3
f(5) = 2 · 5 - 5
f(5) = 5
The points (1, - 3) and (5, 5) are part of the function f(x) = 2 · x - 5.
Case B
f(1) = 2 · 1² - 8 · 1 + 7
f(1) = 1
f(4) = 2 · 4² - 8 · 4 + 7
f(4) = 7
f(5) = 2 · 5² - 8 · 5 + 7
f(5) = 17
The point (1, 1) is part of the function f(x) = 2 · x² - 8 · x + 7.
Case C
f(1) = 2√(1 - 4) + 1
f(1) = NaN
f(4) = 2√(4 - 4) + 1
f(4) = 1
f(5) = 2√(5 - 4) + 1
f(5) = 3
The point (4, 1) is part of the function f(x) = 2√(x - 4) + 1.

Answers

Answer:
if and only if the rectangle is a square
Step-by-step explanation:
The angle bisectors of a rectangle will meet at a single point if, and only if, the rectangle is a square.
In general, a rectangle does not have an incenter.
__
The incircle must be tangent to all sides of the polygon. That cannot be the case unless the rectangle has its length equal to its width. That is, it must be a square.

Answer:
6. C multiply the first equation by -7 ...
7. A parallel lines
Step-by-step explanation:
6. The idea of elimination is to create equations that have opposite coefficients for one of the variables. In this set of equations, there are two simple ways to achieve that.
On is to multiply the second equation by -2 (so x-coefficients are 4 in the first equation and -4 in the second equation).
The other is to multiply the first equation by -7 (so y-coefficients are -7 in the first equation and +7 in the second equation).
This latter method is described in answer choice C.
__
7. Equations are more easily compared if they are in the same form. Here, "standard form" is nice. To put the second equation in standard form, we must remove a factor of 3 from all of the numbers:
3(2x) +3(y) = 3(4)
2x +y = 4
We see that this differs from the first equation only in that it has a different right-side constant. That means it describes a parallel line.

Find the monthly house payments necessary to amortize each loan. Then calculate the total payments and the total amount of interest paid. $175,000 at 6.24% for 30 years. Can anyone show how to set up this problem?
Answers
Answer:
Monthly payment= $1,076.37
Step-by-step explanation:
Giving the following information:
$175,000 at 6.24% for 30 years.
First, we need to calculate the future value of the loan. We need to use the following formula:
FV= PV*(1+i)^n
PV= 175,000
n= 12*30= 360 months
i= 0.0624/12= 0.0052
FV= 175,000*(1.0052^360)
FV= $1,132,220
Total interest= 1,132,220 - 175,000= $957,220
Now, we can calculate the monthly payment:
Monthly payment= (FV*i)/{[(1+i)^n]-1}
Monthly payment= (1,132,220*0.0052) / [(1.0052^360) - 1]
Monthly payment= $1,076.37

If y varies directly with x and y=20.4 when x=6, find the value of y when x=-5?
A. Y=17
B. Y=24.48
C. Y=1.47
D. Y=3.4
Answers
Answer:
y=-17
Step-by-step explanation:
y=mx
20.4=m×6
20.4÷6=m
3.4=m
y=3.4×-5
y=-17
The value of the variable 'y' at x = 5 will be 17. Then the correct option is A.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
If y varies directly with x. Then we have
y ∝ x
y = kx
At x = 6 and y = 20.4, then the value of the constant k is calculated as,
20.4 = k(6)
k = 20.4 / 6
k = 3.4
Then the equation is given as,
y = 3.4 x
The value of the variable 'y' at x = 5 will be calculated as,
y = 3.4 (5)
y = 17
The worth of the variable 'y' at x = 5 will be 17. Then, at that point, the right choice is A.

Find the area of the shape.
Answers
Answer:
36*sqrt(3)
Step-by-step explanation:
Remark
Use the Pythagorean theory to find the height. Use that height to find the area of the rectangle and the triangle Or
You can find the area of the trapezoid which requires only 1 step after you find the height.
Height
c = 8
b = 4
a = ?
a^2 + b^2 = c^2
a^2 + 4^2 = 8^2
a^2 + 16 = 64
a^2 = 64 - 16
a^2 = 48
a^2 = 16 * 3
sqrt(a^2) = sqrt(16*3)
a = 4 * sqrt(3)
That's the height
Trapezoid
b1 = 7
b2 = 7 + 4 = 11
h = 4*sqrt(3)
Area = (b1 + b2)*h / 2
Area = (7 + 11)* 4*sqrt(3)/2
Area = 18 * 2 sqrt(3)
Area = 36* sqrt(3)

B = [cos(kθ) + i sin(kθ)] ∙ [cos(θ) + i sin(θ)]

Answer: D. cos(kθ + θ) + i sin(kθ + θ)
Step-by-step explanation:
The screenshot pretty much speaks for itself, but you can see that the proof ends with cos[(k + 1)θ] + i sin[(k + 1)θ]. That means that addition is happening in Step D, and that the expressions in the cosine and sine parts are the same. So, the correct option is D. Hope that helps!
