= 16
Step-by-step explanation:
where there's x put-3 and where there's y put-5
I don't see =0 so I don't believe you will have to equate further
Answer:
-16
Step-by-step explanation:
Hello There!
For this one we also need to plug in the values and solve
(-3+(-5)(-3-(-5)
first lets distribute the -3 to -3 and -(-5)
-3x-3=9
-3x5=-15
9-15=-6
now lets distribute the -5 to the -3 and -(-5)
-5x-3=15
-5x5=-25
-25+15=-10
-10-6=-16
so the answer would be -16

What is the approximate area of the figure below?
Answers
Answer:
96
Step-by-step explanation:
Area of circle: pi * r^2
r = half diameter = 4/2 = 2
pi * 2^2 = 12.566 cm^2
Rectangle: L * W
4 * 6 = 24 cm^2 for rectangle
Add both areas
12.566 + 24 = 36.566
Solution: 36.57 cm^2

Two forces of 90 newtons and 58 newtons act simultaneously on an object. The angle between the two forces is 57°. Find the magnitude of the resultant, to the nearest 10th of a newton.
Answers
Answer:
131.0 N
Step-by-step explanation:
Let the 90 N force is acting a horizontal force on the object
Horizontal force = 90 + 58sin33
Vertical force = 58cos33
∴The resultant force = √(90 + 58sin33)² + (58cos33)²
= 131.0 N

Tell whether the ordered pair (-1,3) is a solution of the system of linear equations. y=-7x-4 and y=8x+5
Answers
Answer:
Since it does not plug in to the second linear equation, the ordered pair is not a solution of the linear system.
Step-by-step explanation:
(-1,3); y = -7x -4 y = 8x + 5 3 =7 - 4 3 =/ - 8 + 5
For a system of equations to have no real solution, the lines of the equations must be parallel to each other. The ordered pair (-1,3) is not the solution of the given system of equations.
What is the System of equations?Inconsistent SystemFor a system of equations to have no real solution, the lines of the equations must be parallel to each other.
Consistent System
1. Dependent Consistent System
For a system of the equation to be a Dependent Consistent System, the system must have multiple solutions for which the lines of the equation must be coinciding.
2. Independent Consistent System
For a system of the equation to be an Independent Consistent System the system must have one unique solution for which the lines of the equation must intersect at a particular.
The solution of the equation can be found by plotting the equation on the graph. Therefore, the point at which the equation will intersect will the solution of the system of equation.
Since the solution of the system of equation is (-0.6, 0.2), there exists only one single solution for the system of equation. therefore, the (-1,3) is not the solution of the system of equation.
Hence, the ordered pair (-1,3) is not the solution of the given system of equations.

What is the approximate area inside the rectangle but
outside the semicircle?
Answers
Answer:
128 - 32pi
OR
27.469
Step-by-step explanation:
The area of the rectange is 8 x 16 = 128
The area of the semicircle is pi * 8^2 divided by 2
(pi * 8^2)/2
(pi * 64)/2
pi * 32
So the area of the rectangle outside the semicircle is: 128 - 32pi
In approximate form it is: 27.469
F(x)=x^2+1 what is f(f(x))?
Answers
Answer:
Answer
Find out f(f(x)) .
To prove
As given in the question
f(x) = x² + 1
Now
f(f(x)) = f (x² + 1)
Now find out the value of f (x² + 1).
f(f(x)) = f (x² + 1)
= (x² + 1)² + 1
Using formula
(a + b)² = a² + b² + 2ab
Apply in the above function
f(f(x)) = (x² + 1)² + 1
f(f(x)) = [tex]x^{4}[/tex] + 1 + [tex]2x^{2}[/tex] + 1
Simplify
f(f(x)) = [tex]x^{4}[/tex] + [tex]2x^{2}[/tex] + 2
Thus the value of f(f(x)) is: f(f(x)) = [tex]x^{4}[/tex] + [tex]2x^{2}[/tex] + 2

Lebrun loaned $20,000 to his daughter to help her buy a house. When she sold the house four years later, she paid him the $20,000 along with an interest of $3000. What was the annual interest rate? Round answer to two decimal places.
Answers
Answer:
3.75%
Step-by-step explanation:
Total interest (4 years) - $3000
Annual interest (1 year) - $3000 ÷ 4 = $750
Annual interest rate (1 year) - [tex]\frac{750}{20 000}[/tex] × 100% = 3.75%
Checking:
Interest after 1 year - [tex]\frac{3.75}{100}[/tex] × $20,000 = $750
Interest after 4 years - $750 × 4 = $3000 (Correct)
Answer:
The interest rate was 3.75%.
Step-by-step explanation:
Attention: I am assuming simple interest here since I am not told otherwise.
Knowing Lebrun's interest was a total of $3000 on the $20000 loan, we can safely assume that it was a $750 interest flat fee paid on top of the loan amount dividing the $3000 by the four years it took for them to return the loan.
Dividing the amount of interest, in dollars, by the total amount of the loan and multiplying by 100, you will get the interest rate on the loan:
[tex]\frac{750}{20000}=\frac{75}{2000}=\frac{15}{400}=\frac{3}{80}\\\\\frac{3}{80}*100=\frac{3}{8}*10=\frac{30}{8}=3\frac{3}{4} =3.75\%[/tex]
