Answer:
53.88 or [54.0]
Step-by-step explanation:
A bicycle is worth 500 dollars , decreases in value by 7.8% per year.Set up a function to model this situation.Use the model to show how much the bike will be worth after 5 years.
Answer:
$333.138
Step-by-step explanation:
Given that:
Initial value = $500
% decrease in value per year = 7.8% = 0.078
Price after t years is given by :
P(t) = initial value(1 - 0.078)^t
Where, t = number of years
Price after 5 years :
t = 5
P(5) = 500(1 - 0.078)^5
P(5) = 500(0.922)^5
P(5) = 500 *0.666276668105632
P(5) = 333.138334052816
= $333.138
Gabrielle is 10 years younger than Mikhail. The sum of their ages is 40. What is Mikhail's age
Answer:
Mikhail is 25 and Gabrielle is 15
Step-by-step explanation:
g = (m-10) and g+m = 40
We'll substitute that first equation into the second
(m-10) + m + 40
2m - 10 = 40
2m = 50
m = 25
Answer:
A) G +10 = M
B) G + M = 40
A) G -M = -10 Adding A) + B)
2 G = 30
Gabrielle is 15
Mikhail is 25

Population of Jacksonville was 3810 and 2010 and is growing at an annual rate of 3.5% if the growth rate continues what will the approximate population in 2023
Answer:
FV= 5,958.67 = 5,959
Step-by-step explanation:
Giving the following information:
Current population (Present Value)= 3,810
Growth rate (g)= 3.5% annual
Number of periods (n)= 13 years
To calculate the future number of people (FV), we need to use the following formula:
FV= PV*(1+i)^n
FV= 3,810*(1.035^13)
FV= 5,958.67 = 5,959
Which inequality is true?
0 -9 > 13
-10 > 9
0 -10 > -9
0 -13 < -10
Answer:
The last one.
1)0-9=-9
And a negative number is always smaller than a positive one
2)Negative number always smaller than positive
3)The smaller a negative number is, the closer it is to zero, so the greater it is
4)correct

Which value is a solution for the equation tan x/2 = -1?
A. 5pi/4
B. 7pi/4
C. 3pi/4
D. 3pi/2
Answer:
D
Step-by-step explanation:
What we have to do is to find the arc tan
x/2 = arc tan (-1)
tan is negative on the 4th and second quadrant
arc tan (-1) = 135 or 315
pi is 180 degrees
so we have;
135 is 3 pi/4
multiplied by the 2
= 6 pi/4 which is 3 pi/2
315 is 7 pi/4 which is same as 7 pi/2 when we multiply by 2
Answer:
the answer is d
Find the values of x and y plz
Answer:
x= 40, y= 140
Step-by-step explanation:
if two parellel lines cut by a transversal then same-side interior angles are supplementary.
180-140 = x
x = 40
x and y are suplementary
180-40 = 140

Reflect the figure over the line y= -x -2
pls help no tutors know the answer!!
Answer: You'll have a quadrilateral with the following points
(5, -5)(4, -7)(6, -7)(8, -3)A diagram is posted below.
===================================================
Explanation:
The given quadrilateral has four unmarked points. I'll add the point labels A,B,C,D such that
A = (-3, 3)B = (-5, 2)C = (-5, 4)D = (-1, 6)I started at the lower right corner and worked my way clockwise.
----------------
Let's shift the line y = x-2 up two units so that it moves to y = x
We'll need to shift every point of the quadrilateral up two units as well.
So we have these new point locations after the shifting has occurred.
A' = (-3, 5)B' = (-5, 4)C' = (-5, 6)D' = (-1, 8)----------------
Now we need to reflect over the diagonal line. The rule to reflect over the line y = x is as simple as swapping the x and y coordinates.
So we can say [tex](x,y) \to (y,x)[/tex]
A point like (-3, 5) moves to (5, -3)
We have these new locations
A'' = (5, -3)B'' = (4, -5)C'' = (6, -5)D'' = (8, -1)----------------
The last thing to do is to shift everything down 2 units. This is to undo the first step we did when we shifted everything up by 2 units.
Doing this leads to these locations
A''' = (5, -5)B''' = (4, -7)C''' = (6, -7)D''' = (8, -3)Check out the diagram below.
solve:
1 + 0 = ?
4 + 0 = ?
3 + 0 = ?
do you get it?
Answer:
1+0=1
4+0=4
3+0=3

Last year, the ratio of literate and illiterate people of Rashkundu Village was
4:1. If the population of the village is 6550, let's find the numbers of literate
and illiterate people.
Step-by-step explanation:
Let the literate and illiterate people of Rashkundu Village be 4x and x respectively then 4x + x = 65505x = 6550x = 6550 / 5x = 1310Therefore no. of literate people = 4 * 1310 = 5240no. of illiterate people = 1310 Hope it will help :)Answer:
5,240 literate
1310 illiterate
Step-by-step explanation:
-ratio of literate : illiterate is 1:4
-add the numbers in the ratio (4+1=5)
-divide total population by 5 (6,550/5= 1,310)
-multiply the outcome by 4 to find the number of literate people (1,310*4=5,240 people)
-subtract the number of literate people from total population to find number of illiterate people (6,550-5,240= 1,310 people).

2. What value of x makes the equation
3
113
=
true?
Answer:
i don't understand what your asking, but i hope this helps
Step-by-step explanation:
the process of ascertaining the variable value that makes the equation true is called 'solving' the equation. An equation is a verbalization that two quantities are equipollent. For exp/example:. x + 1 = 4 betoken that when we integrate 1 to the unknown value, 'x', the answer is equipollent to 4
Give an example of a linear function whose graph intersects with the y-axis at the same points as the graphs of the following functions.
y= x+11
y= -9x-6
Answer:
Given functions:
y= x + 11y= -9x - 6They have different y-intercepts, therefore the line to intersect y-axis at the same points is y-axis itself.
The equation is:
x = 0The graph is attached
---------------------------------------
Note. If the question is about the lines above separately, then the answer is following
The first line has y-intercept of 11, any line with same y-intercept is the answer:
y = mx + 11, where m ≠ 1For the second line the equation is:
y = mx - 6, where m ≠ -9Answer:
y = mx + 11, where m ≠ 1
For the second line the equation is:
y = mx - 6, where m ≠ -9

[tex]\frac{-5 + \sqrt{37} }{2}[/tex]
Note:Have no clue if its right
Answer:
see explanation
Step-by-step explanation:
The area (A) of the rectangle = length × breadth, that is
A = BC × CA
= (x + 3)(x + 2) ← expand using FOIL
= x² + 5x + 6
Given that A = 9 , then
x² + 5x + 6 = 9 ( subtract 6 from both sides )
x² + 5x = 3 ← as required

A rectangle Is (2x-3) cm long and (x+7) cm wide. What Is It's area?
Answer:
Step-by-step explanation:
Length (L)= 2x - 3 cm
Breadth (b) = x + 7 cm
Area of the rectangle
= L * b
= ( 2x - 3)(x+ 7)
= 2x(x + 7) - 3(x + 7)
= 2x² + 14x - 3x - 21
=( 2x² + 11x - 21) cm²
hope it helps
Answer:
[tex]2x^{2}[/tex] + 11x -21 [tex]cm^{2}[/tex]
Step-by-step explanation:
Area of a rectangle = Length × Width
= (2x-3)(x+7)
Multiply 2x with x, 2x with +7, -3 with x and -3 with +7
= [tex]2x^{2}[/tex] + 14x - 3x - 21
= [tex]2x^{2}[/tex] + 11x -21 [tex]cm^{2}[/tex]

Let f(x)=√x^2 - 64. Evaluate the function f(-x). What conclusion can be made?
a.) The function is an odd function.
b.) The function is both an even and an odd function.
c.) The function is an even function.
d.) The function is neither an even nor an odd function.
9514 1404 393
Answer:
c.) The function is an even function.
Step-by-step explanation:
Either way you interpret the given function, you have ...
f(-x) = √(-x)^2 -64 = √x^2 -64
f(-x) = f(x) . . . . the function is an even function (only)
