When is the best time to use square roots to solve a quadratic? Choose the one BEST
answer.
A. Perfect square trinomials
B. Difference of squares
C. When there is no b term
D. When the constants are perfect squares
Answer: D, When the constants are perfect squares.
Step-by-step explanation:
the “best” method whenever the quadratic equation only contains x2 terms. That implies no presence of any x term being raised to the first power somewhere in the equation.
Hopefully this helps!

Answer: 4h
Step-by-step explanation:
Rewrite with only sin x and cos x.
sin 3x - cos x
Answer:
sin (3 x) - cos (x)=
= sin (2x + x) - cos (x)=
= sin 2x * cos x + cos 2 x * sin x - cos x = ( using additional formulas )
= 2 sin x cos² x + ( cos² x - sin² x ) sin x - cos x =
= 2 sin x cos² x + ( 1 - sin² x - sin² x ) sin x - cos x =
= 2 sin x cos² x + ( 1 - 2 sin² x ) sin x - cos x =
= 2 sin x cos² x + sin x - 2 sin³ x - cos x
Answer: B )

Nathan jogged 2 /1 4 m i l e s o n M o n d a y . W e d n e s d a y h e j o g g e d 3 /1 3 m i l e s , a n d F r i d a y , h e j o g g e d 2 / 2 3 m i l e s . How far did Nathan jog altogether?
Answer: 8 1/4 miles
Step-by-step explanation:
I think your question isn't well written and should be:
Nathan jogged 2 1/4 miles on Monday. On Wednesday, he jogged 3 1/3 miles and on Friday, he jogged 2 2/3 miles. How far did Nathan jog altogether?
This will be:
= 2 1/4 + 3 1/3 + 2 2/3
= 2 3/12 + 3 4/12 + 2 8/12
= 7 15/12
= 7 + 1 3/12
= 8 3/12
= 8 1/4 miles

Answer:
The calculation for ROC is simple in that it takes the current value of a stock or index and divides it by the value from an earlier period. Subtract one and multiply the resulting number by 100 to give it a percentage representation.
Step-by-step explanation:
what is the value of x in the diagram below?
Answer:
x = 45
Step-by-step explanation:
These two angles are consecutive interior angles. This means they will add up to 180°. We use this information to make an equation.
x + 5 + 130 = 180
x + 135 = 180
x = 45
who is correct alex or jo
Answer:
D
Step-by-step explanation:
Neither Alex nor Jo are correct, because surface area is a 2-dimensional quantity, so it would be given in just square units, not linear nor cubic.

Points (-2, 4) and (-1,1) lie on the same line. Which of the following equations represents the line?
A. y - 1 = -}(x + 1)
B. y - 1 = -3(x + 1)
C. y - 1 = -}(x - 1)
D. y - 1 = -3(x - 1)
Answer:
A
Step-by-step explanation:
There are 2 ways you can do this. I'll show you one!
1. Find the Slope
a. use the slope formla: (y1-y2)/(x1-x2)
(4-1)/(-2-1)= 3/-3= -1
This eliminates both B and D, as their slopes are -3
2. Now analyze the last 2 equations
a. A goes through the ordered pair (-1, 1)
b. C goes through the ordered pair (1, 1)
The line we want goes through (-1, 1), so A is the correct answer!
[tex]y-1=-3(x+1)[/tex] equation represents the line.
What is point slope form?The point slope form is used to find the equation of the straight line which is inclined at a given angle to the x-axis and passes through a given point.
Given points
[tex](x_{1} ,y_{1} )[/tex] = (-1, 1)
[tex](x_{2} ,y_{2} )[/tex] = (-2, 4)
Using point slope form
We know that the equation of line passing through points [tex](x_{1} ,y_{1} )[/tex] and [tex](x_{2} ,y_{2} )[/tex] is
[tex]y-y_{1} =\frac{y_{2}-y_{1} }{x_{2}-x_{1} }( x-x_{1})[/tex]
Therefore equation of line passing through points (-1, 1) and (-2, 4) is
[tex]y-1=\frac{4-1}{-2+1}(x-(-1))[/tex]
[tex]y-1=\frac{3}{-1} (x+1)[/tex]
[tex]y-1=-3(x+1)[/tex]
Option B is correct.

A car is purchase at $20000.The value of the car depreciates at 12.5% a year. What will the value of the car be to the nearest cent after 11 years
Answer: $4603.82
Step-by-step explanation:
Given
The initial cost of a car is [tex]P=\$20,000[/tex]
The rate of depreciation is [tex]i=12.5\%[/tex]
Depreciated value after n years is given by
[tex]\Rightarrow P(1-\frac{i}{100})^n\quad \text{where n=no. of years}[/tex]
Value after 11 years
[tex]\Rightarrow 20,000(1-\frac{12.5}{100})^{11}\\\\\Rightarrow 20000(0.875)^{11}=\$4603.82[/tex]
