the annual interest be if its interest rate is 6_%?
Answer:
(assuming simple interest)
I'll setup the problem and you can do the computation
Step-by-step explanation:
The formula for simple interest:
I = P*r*t
P = deposits
r = interest rate per period (a year)
t = number of periods
P = Php 23,200
r = 0.06
t = 1

Answer:
x = 47.2
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = opp / hyp
cos x = 17/23
Taking the inverse cos of each side
cos ^-1 ( cos x) = cos ^-1 ( 17/25)
x =47.15635696

A doctor is interested in analyzing the increase in systolic blood pressure caused by a certain chemo drug. Would the doctor be more interested in studying the mean, median, or mode of the systolic blood pressures
Answer:
Mean.
Step-by-step explanation:
When a doctor analyzes the increase in systolic blood pressure caused by a certain chemo drug. The doctor would be more interested in studying the mean of the number of observed systolic blood pressures. As mean would give a better understanding of pressure since it involves the use of all observations. However, it is important to keep in mind that all the units should be considered for the average.

50% of a number is x. What is 100% of the number? Assume x > 0.
Answer:
2x > 0
Step-by-step explanation:
[tex]\frac{50}{100} :\frac{x}{y}[/tex]
50 × y = x × 100
50y = 100x
50y ÷ 50 = 100x ÷ 50

The mean of eight numbers is 41. The mean of two of the numbers is 29. What is the mean of the other six numbers
Answer:
45
Step-by-step explanation:
The mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
Given the mean of 8 numbers is 41 , then
[tex]\frac{sum}{8}[/tex] = 41 ( multiply both sides by 8 )
sum of 8 numbers = 328
Given the mean of 2 numbers is 29 , then
[tex]\frac{sum}{2}[/tex] = 29 ( multiply both sides by 2 )
sum of 2 numbers = 58
The sum of the remaining 6 numbers = 328 - 58 = 270 , so
mean = [tex]\frac{270}{6}[/tex] = 45
The mean of the other 6 numbers = 45

9. Divide 15x^7-45x^5/3x^4
10. Divide (3x-2)(x-4)-(x-4)(6-5x)/(4-x)(8x-1)
The rational equations after division is
a) A = ( 5x³ - 15x )
b) B = - ( 3x - 2 ) ( x - 4 ) ( 6 - 5x ) / ( 8x - 1 )
What is rational function equation?
A rational equation can be defined as an equation that involves at least one rational expression
A rational function is a function of the form f( x )=P( x ) / Q( x ) ,
f( x ) = P( x ) / Q( x ) , where P( x ) and Q( x ) are both polynomials.
A rational function f ( x )=P( x ) / Q( x )
f( x ) = P( x ) / Q( x ) may have a vertical asymptote
The domain is the set of all real numbers for which Q( x ) ≠ 0
Given data ,
a)
Let the first function be P ( x ) = ( 15x⁷ - 45x⁵ )
Let the second function be Q ( x ) = 3x⁴
On simplifying , we get
A = P ( x ) / Q ( x )
A = ( 15x⁷ - 45x⁵ ) / 3x⁴
A = 3x⁴ ( 5x³ - 15x ) / 3x⁴
On further simplification , we get
A = ( 5x³ - 15x )
b)
Let the first function be P ( x ) = ( 15x⁷ - 45x⁵ )
Let the second function be Q ( x ) = 3x⁴
On simplifying , we get
B = P ( x ) / Q ( x )
B = ( 3x - 2 ) ( x - 4 ) ( x - 4 ) ( 6 - 5x ) / ( 4 - x ) ( 8x - 1 )
B = - ( 3x - 2 ) ( x - 4 ) ( x - 4 ) ( 6 - 5x ) / ( x - 4 ) ( 8x - 1 )
On further simplification , we get
B = - ( 3x - 2 ) ( x - 4 ) ( 6 - 5x ) / ( 8x - 1 )
Hence , the rational equations are solved

Which of the following changes would double the force between two charged particles?
A. Doubling the amount of charge on each particle
B. Increasing the distance between the particles by a factor of 2
C. Decreasing the distance between the particles by a factor of 2
D. Doubling the amount of charge on one of the particles
Answer:
D. Doubling the amount of charge on one of the particles
Step-by-step explanation:
Force between charged particles:
The force between two charged particles is given by:
[tex]F = \frac{kq_1q_2}{r^2}[/tex]
In which k is the coulomb constant, [tex]q_1[/tex] and [tex]q_2[/tex] are the charges and r is the distance between them.
Which of the following changes would double the force between two charged particles?
Doubling the amount of force on both particles quadriplies, as does decreasing the distance between the particles by a factor of 2(we would have a division by 1/4 which is the same as a multiplication by 4).
Increasing the distance would decrease the force.
So the correct option is D, one of the particles' charges being multiplied by 2 means that the equation for F is multiplied by 2, and thus, the force is doubled.

Which triangle is similar to triangle T?
Triangle T
40
1100
110
50
Answer:
the angle that is 110° and 30°
Step-by-step explanation:
The triangle is similar to triangle T is triangle III.
Thus, option (c) is correct.
In the given triangle,
Two angles are 110 and 40.
Using Angle sum property in given triangles as
Angle 1 + Angle 2 + Angle 3 = 180
110 + 40 + Angle 3= 180
150 + Angle 3= 180
Angle 3 = 180 - 150
Angle = 30
Thus, the angles are 110, 40 and 30.
Therefore, Triangle III is similar to triangle T.

Find the zeros of y = 4x2 – 12x – 16
Answer:
x=-1 or x=4
Step-by-step explanation:
First divide by 4 to get rid of the factor 4 at x², then you have:
x² - 3x - 4 = 0
to factor that, look for two numbers that when added, give -3, and when multiplied, give -4. This is guesswork but usually doable:
-4 + 1 = -3
-4 * 1 = -4
so -4 and +1 are our numbers.
The factorization is therefore: (x - 4)(x + 1) = 0, and the solutions are
x-4 = 0 or x+1 = 0, so x=4 or x=-1

Step-by-step explanation:
The sum of the angles of a triangle is 180

Combine like terms
58x +6 = 180
Subtract 6 from each side

58x = 174
Divide by 58
58x/58 =174/58

Answer:
A. x^2 +(y -7)^2 = 625
B. S'(39, 20)
C. P'(19, 35)
D. C'(56.5, 17.5)
Step-by-step explanation:
Part A: The infinite number of points with those coordinates will be the solutions to the equation of a circle centered at Q with radius 25. The standard form equation of a circle with center (h, k) and radius r is ...
(x -h)^2 +(y -k)^2 = r^2
For (h, k) = (0, 7) and r=25, the equation for the points of interest is ...
x^2 +(y -7)^2 = 625
__
Part B: It is useful to recognize ΔROQ as a right triangle with sides that are the Pythagorean triple (7, 24, 25). (You can figure side RO using the Pythagorean theorem if you're not familiar with this triple.) This means the coordinates of R are (24, 0) and the horizontal distance to the line x=39 is 39-24=15 units.
If we name point X(39, 0), then triangle RXS' has sides RX = 15 and RS' = 25. We recognize these as a multiple of the Pythagorean triple (3, 4, 5), so we know that XS' = 20, (Again, you can figure this using the Pythagorean theorem if you're not familiar with the relevant triples.)
The coordinates of S' are (39, 20).
__
Part C:
Point S' is 15 right and 20 up from R. A vector at right angles to RS' will have the coordinates swapped, and one of them negated. Point P' will be 20 left and 15 up from point S', so ...
P' = S' +(-20, 15) = (39, 20) +(-20, 15) =
P' = (19, 35)
__
Part D: After rotation, the center (C) of the square is the midpoint of RP', so is ...
C = (R +P')/2 = ((24, 0) +(19, 35))/2 = (43, 35)/2 = (21.5, 17.5)
Reflection over the line x=39 is accomplished by the transformation ...
(x, y) ⇒ (2·39 -x, y)
C(21.5, 17.5) ⇒ C'(78 -21.5, 17.5) = C'(56.5, 17.5)
