to calculate percent increase use
[tex]\frac{increase}{original}[/tex] × 100%
increase = $650 - $525 = $125
percent increase = [tex]\frac{125}{525}[/tex] × 100% = 24% → B
Answer:
The answer is B) 24%
Step-by-step explanation:
The formula for percentage increase is given as:-
Percentage Increase = ( New Price - Old Price ) /old price * 100
old price = $525
New Price = $650
Percentage Increase = 24%
Hence the price increases by 24%

Line segments JK and JL in the xy-coordinate plane both have a common endpoint J(-4,11) and midpoints at M, (2, 16) and M2 (-3,5), respectively. What is the distance between M, and M2? Round to the nearest tenth.
Answer:
12.1
Step-by-step explanation:
We use the formula for the distance between two arbitrary points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] in the xy-coordinate plane, that is:
[tex]d=\sqrt{(x_1-x_2)^2 + (y_1-y_2)^2}[/tex]
So, replacing the points [tex]M=(2,16)[/tex] and [tex]M_2=(-3,5)[/tex], we obtain:
[tex]d=\sqrt{(2-(-3))^2 + (16-5)^2}\\d=\sqrt{(2+3)^2 + (16-5)^2}\\d=\sqrt{5^2 + 11^2}\\d=\sqrt{146 }=12.083045... \simeq 12.1[/tex]
that is the answer.
note: observe that we only use the coordinates between the two midpoints and not the point J.
Q#..12 anybody help me?
Answer: First option. x-intercept is -5; y-intercept is -7/4
Solution:
1) To find the x-intercept we replace y by 0, and solve for x:
-(7/5)x-4y=7
-(7/5)x-4(0)=7
-(7/5)x-0=7
-(7/5)x=7
Multiplying both sides of the equation by -(5/7)
-( 5/7)[-(7/5)]x=-(5/7)(7)
x=-(5*7)/7
x=-35/7
x=-5
The x-intercept is -5
2) To find the y-intercept we replace x by 0, and solve for y:
-(7/5)x-4y=7
-(7/5)(0)-4y=7
-0-4y=7
-4y=7
Dividing both sides of the equation by -4:
-4y/(-4)=7/(-4)
y=-(7/4)
The y-intercept is -(7/4)

given sin theta = 2/5 and 0 theta 90 find sin 2 theta
Given: sin theta = 2/5. This tells us that the lengths of the opp side and the hyp are 2 and 5 respectively. The adj side is found using the Pyth. Thm.: 5^2-2^2= 25-4 = 21, so that the adj side is sqrt(21).
The double angle formula for the sine is sin 2theta = 2 sin theta *cos theta.
In this particular problem, the sine of 2theta is 2*(2/5)*[sqrt(21) / 5], or:
(4/25)*sqrt(21).
Answer:
The value of [tex]\sin^2 \theta=\frac{4}{25}[/tex]
Step-by-step explanation:
Given : [tex]\sin \thet=\frac{2}{5}[/tex] and [tex]0<\theta<90[/tex]
To find : The value of [tex]\sin^2\theta[/tex] ?
Solution :
We have given the value of [tex]\sin \thet=\frac{2}{5}[/tex] and [tex]0<\theta<90[/tex]
To find [tex]\sin^2\theta[/tex] we just have to square [tex]\sin\theta[/tex]
[tex]\sin \theta=\frac{2}{5}[/tex]
Squaring both sides,
[tex](\sin \theta)^2=(\frac{2}{5})^2[/tex]
[tex]\sin^2 \theta=\frac{4}{25}[/tex]
Therefore, The value of [tex]\sin^2 \theta=\frac{4}{25}[/tex]

Factor. 9x^2+27x+45
9x^2 + 27x + 18 . hope i helped
The factors of the quadratic equation are (-3 - √11i) and (-3 + √11i).
What is a quadratic equation?A quadratic equation is an algebraic equation of degree 2.
Given a quadratic equation 9x² + 27x + 45 = 0.
We know simplifying a quadratic equation doesn't change the roots of the equation.
∴ We can divide each of the terms by 9 which makes the quadratic equation x² + 3x + 5 = 0.
Now two numbers which multiplied to 5 and add to 3 are not possible for real numbers, therefore, the roots must be imaginary.

What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is that one number is 11 more than twice another number and the sum of the numbers is twice their difference
Assume that the numbers are (x) and (y). Then, we can the model the equation as follows -
x = 2y + 11
x + y = 2(x - y)
Simplifying the equations, we can write -
x + y = 2(x - y)
x + y = 2x - 2y
2x - x - 2y - y = 0
x - 3y = 0
y = x/3
Put y = x/3 in x = 2y + 11, we get -
x = 2x/3 + 11
x - 2x/3 = 11
x/3 = 11
x = 33
then y = 33/3 = 11
Therefore, the numbers are x = 33 and y = 11 respectively.

School guidelines require that there must be at least two shop around for every 25 students going on the school trip how many chaperones must there be for 53 students
2*53/25 = 4.24
4 is not enough to maintain the required ratio, so there must be 5 chaperones, minimum.

Presumably, the guidelines contain additional information regarding whether the number of chaperones can be odd. Sometimes, two are required so that one can be taking care of a student while the other handles the remaining students (or calls for emergency aid). In that case, the minimum for 53 students may be 6 chaperones.

How do you determine the minimum and maximum values of this function?
Answer:
Make use of your knowledge of the maximum and minimum of the cosine function. Then scale and translate according to the way that function is scaled and translated to make f(x).
Step-by-step explanation:
f(x) is the cosine function, multplied by 4 and with 9 added to the result.
The minimum of the cosine function is -1. Multiplying that by 4 gives -4, and adding 9 gives 5.
The maximum of the cosine function is +1. Multiplying that by 4 gives +4, and adding 9 gives 13.
The minimum and maximum of f(x) are 5 and 13, respectively.

Answer:
x = (2,0)
y = (0,4)
Step-by-step explanation:
Solve For x:
Lets take y as 0 so the equation is 0 = -2x + 4, and if we simplify the expression we get x = 4/2 which s x = 2 so the answer for x is (2,0)
Solve for y:
Lets take x as 0 so the equation is y = -2 · 0 + 4 which simplyfied to y = 4, so the answer for y is (0,4)
