Walter buys a new truck for $38,000. The truck loses value at a rate of 16% per year. Which equation models the value, V(t), in dollars, of the truck after t years?
A.V(t) = 38000(0.16)t B. V(t) = 38000(0.84)t
C.V(t) = 38000(1.16)t D. V(t) = 38000(-0.84)t
Answer:
V(t) = 38000(0.84)^t

Answer:
5/6
Step-by-step explanation:
create a proportion:
(1/2÷3/5) = (x÷5/5)
cross-multiply to solve for 'x':
3/5x = 1/2
6x = 5
x = 5/6
Answer:
[tex]\frac{5}{6}[/tex]
Step-by-step explanation:
Ok so one hour is 1/1.
1/1 - 3/5 = 2/5
So Landon has 2/5 of an hour left.
Let's find out how much 1/5 of an hour is in the test.
1/2 ÷ 3 = 1/6
So 1/5 of an hour = 1/6 of the test.
1/6 * 2 = 1/3
1/2 + 1/3 = 5/6
Recall the equation for a circle with center ( h , k ) and radius r . At what point in the first quadrant does the line with equation y = 2.5 x + 4 intersect the circle with radius 5 and center (0, 4)?
Answer: The required point = (1.857,8.643)
Step-by-step explanation:
Equation of circle with center (h,k) and radius r: [tex](x-h)^2+(y-k)^2=r^2[/tex]
Given: Radius = 5 , center = (0,4)
Eqation of circle: [tex](x-0)^2+(y-4)^2=5^2[/tex]
[tex]x^2+(y-4)^2=25[/tex]
[tex]x^2+(2.5x+4-4)^2=25[/tex] [Using equation y = 2.5 x + 4 ]
[tex]x^2+(2.5x)^2=25[/tex]
[tex]x^2+6.25x^2=25[/tex]
[tex]7.25x^2=25[/tex]
[tex]x^2=3.44827586207[/tex]
[tex]x=1.857[/tex]
[tex]y= 2.5(1.857)+4[/tex]
[tex]=8.6425[/tex]
Hence, the required point = (1.857,8.643)
2. Aaron baked two identical cakes. He cut one into 9 equal slices and the other into 19 equal slices.
a) Show that ⅔ of the 9-slice cake gives the asme number of pieces as 1/
3 of the 18 slice cake.
2/3 x 9 = 6 slices
1/3 x 18 = 6 slices
Hence they give the same number of slices.
Yani walked the perimeter of a square patio that was 5.3 meters on each side. What is the distance that Yani walked?
Answer:
21.2 meters
Step-by-step explanation:
The perimeter of a square = 4s
Where, s = side length of the square
Given that, side length, s = 5.3 meters
Perimeter = (4 * 5.3) = 21.2 meters.
Hence, distance Yani walked = perimeter of square patio = 21.2 meters
PLEASE HELP WITH ALGEBRA!!!
Answer: aₙ = 3 + 4ⁿ⁻¹
So the formula would be:
aₙ = 3 + 4ⁿ⁻¹
Where a₁ = 3
Common Ratio (r) = 4
And n = the term number that needs to be found out
Step-by-step explanation:
Let's check if the answer is right:
To find the 1st number in the term we can substitute 1 in for n in the equation:
a₁ = 3 + 4¹⁻¹
a₁ = 3 + 4⁰
a₁ = 3 + 1
a₁ = 4
And if going back and checking the first number in the sequence given is indeed 4, therefore this equation is correct

A committee consisting of faculty members and students is to be formed. Every committee position has the same duties and voting rights. There are faculty members and students eligible to serve on the committee. In how many ways can the committee be formed?
Answer:
Total number of ways of making the core committee = 3150
Step-by-step explanation:
Complete Question
A committee consisting of 2 faculty members and 4 students is to be formed. Every committee position has the same duties and voting rights. There are 6 faculty members and 10 students eligible to serve on the committee. In how many ways can the committee be formed?
Solution
Total Faculty members = 6
Total Students = 10
Out of 6 faculty members, 2 will be chosen for the committee
While 4 students will be chosen out of 10 to be in the committee.
Hence,
Total number of ways of making the core committee = 6C2 * 10C4
= 15*210
= 3150

for every 2 teaspoons of vanilla it is 2/5, so for one it has to be 1/5 because 1/5 cup plus 1/5 cup will be 2/5 for 2 teaspoons.
Ms. Shaddai writes 3g=51 and (15, 16, 17) on the board. Tell if each value in the set is a solution of the equation.
Answer:
17 is the answer.
Step-by-step explanation:
There are two ways to do this problem:
a. plug in each value and multiply it by 3. 3x15 is 45, 3x16 is 48, and 3x17 is 51, which is your answer.
b. divide both sides by three and you would get g=17.

Identify the center and radius of each. Then sketch the graph.
(x-1)^2 +(y+ 3)^2= 4
pls tell me the radius also
Answer:
Step-by-step explanation:
Can't sketch it, obviously, but I can help you understand how to do that on your own. The standard form of a circle is
[tex](x-h)^2+(y-k)^2=r^2[/tex] where h and k are the coordinates for the center of the circle. The super-important thing to remember here is that the standard form is ALWAYS (x-h)^2 (the minus being the important part!). That means that if the expression is
[tex](x-2)^2[/tex] for example, it can be rewritten to be understood as
[tex](x-(+2))^2[/tex] where the positive implies movement to the right. If the expression is
[tex](x+2)^2[/tex] for example, it can be rewritten to be understood as
[tex](x-(-2))^2[/tex] where negative is indicative of movement to the right. The location of the center of a circle will help you graph it.
In our circle, we have a -1 in with the x and a +3 in with the y. The -1 indicates movement to the right 1 unit (positive 1), while the +3 in with the y indicates movement to the left 3 units (-3). Therefore, the movement of the circle also indicates the coordinates of the center: (1, -3).
The radius is found in the square root of the number to the right of the equals sign. Ours is a 4; therefore, the radius is 2.
To draw this circle, locate the point (1, -3) on your graph paper and put a dot. Then count directly to the right 2 units and make a dot, directly to the left 2 units and make a dot, directly up 2 units and make a dot, and directly down 2 units and make a dot. Connect the outer 4 dots in as smoothly as possible to get a circle. And there you go!
Which scatter plot below shows both linear association and negative association between the two variables?
Answer:
C
Step-by-step explanation:
It is C because negative means it will be going down so it isnt A or B and you can see D has a curve up before it goes down so C is the best answer
hope this helps

angles in a triangle add up to 180 degrees
the little squares in the corner mean its a right angle (90 degrees)
the two lines like in the op triangle mean the two angles downwards are the same.
angles in a semicircle add up to 180 degrees
3 lines mean all angles are the exact same
(Sorry i forgot 2 angles dont know which ones i forgot but with the info i gave you should be able to work those two out :)
