Answer:
The function stated by Tucker is incorrect.
V(t) = 4600(0.8)^t
Step-by-step explanation:
Given the function :
V(t)=4,600(0.4)2t
The initial value of equipment = 4600
Decay rate = 40% of very 2 years
The value of equipment t years after purchase
The exponential decat function goes thus :
V(t) = Initial value * (1 - decay rate)^t
The Decay rate per year = 40% /2 = 20% = 0.2
V(t) = 4600(1 - 0.2)^t
V(t) = 4600(0.8)^t

explain how to multiply 641 by 63.
Answer:
sure
Step-by-step explanation:
1) line up 641 and 63
641
x__63_
2) multiply 3 by 1 then 4 then 6 and carry the tenths place number if there is one
1
641
x__63_
1923
3) add a zero under the 3 to hold the ones place and multiply 6 by 1 then 4 then 6 and since we’re working with the tenths place now and dont forget to carry numbers if you need to
2
641
x__63_
1923
38460
4) add your two numbers together
1 1
38460
+___1923_
40383
so that is your answer “40383”
lol sorry that this was so long
Answer:
The answer is 40,383
Step-by-step explanation:
First, you set up the multiplication. 641 is the largest number so it goes on top. 63 is the smallest number so it goes on the bottom. Draw your line. Next, you multiply 3 by 1 which is 3. Then you multiply 3 by 4 and you get 12. Since this is a two digit number, the 2 goes below the line and the 1 you place on top of the 6. Next, you multiply 3 by 6 and get 18, but don't forget the 1 you placed on top! So you get 19. Then you cross out the 1 on top of the 6 and cross out the 3. After you cross out the numbers you add a 0 under the 3 with the number that is under the line. Then you start multiplying 6x1 which is 6. 6x4 which is 24, place the 4 under the line and bring the 2 on top of the 6. Then multiply 6x6 which is 36, add the 2 you brought on top which is 38. After you did all that work, add all the numbers and your answer is 40,383! Hope this made sense and hope it helps! :3
Ben needs to replace two sides of his fence. One side is meters long, and the other is meters long. How much fence does Ben need to buy?
Answer:
696 39/100 meters
Step-by-step explanation:
Ben needs to replace two sides of his fence. One side is 367 9/100 meters long, and the other is 329 3/10 meters long. How much fence does Ben need to buy?
Side A = 367 9/100 meters
Side B = 329 3/10 meters
How much fence does Ben need to buy?
Total fence Ben needs to buy = Side A + side B
= 367 9/100 + 329 3/10
= 36709/100 + 3293/10
= (36709+32930) / 100
= 69639/100
= 696 39/100 meters
Ben needs to buy 696 39/100 meters

0.15 × $2910 = $436.50
__
B) The total of the 18 monthly payments of $161.56 each is ...
18 × $161.56 = $2908.08
__
C) The total amount paid for the car is the sum of the down payment and the monthly payments:
$436.50 +2,908.08 = $3,344.58

Answer:
y = 4x+1
Step-by-step explanation:
Which line is parallel to y = 2 and goes through the point (3, 4)?
Answer:
y = 4
Step-by-step explanation:
Since it's y = 2,
there's no slope
So y = 4 is parallel to y = 2
y = 4 goes through the point (3, 4) since it's just one horizontal line hitting the y-axis
(-4,9);m=-1/2
Write the equation in point slope form
Answer: y-9=-1/2 x (x+4)

AD is tangent to circle B at point C. What is the measure of BCA? O 40° O 50° O 90° O 180°
Answer:
C
90
Step-by-step explanation:
B is likely the center, I think. You can't do it otherwise.
The tangent and a radius of a circle meet at 90o
therefore the answer is 90.
All of this could be confirmed with a diagram.

Find a85 of the sequence 4,9,14,19,….
Answer: 424
Step-by-step explanation:
Bart designed a logo using circles of different sizes. The diameters of three of the circles are
shown. Which measurement is closest to the area of the largest circle in square centimeters?
A 20.7 cm2
B 136.8 cm2
C 34.2 cm2
D 65.1 cm
Answer:
B 136.8 cm²
Step-by-step explanation:
Add the diameters of the three smaller circles to find the diameter of the largest circle.
D = 3 cm + 2.5 cm + 1.1 cm = 6.6 cm
area = πr²
area = 3.14 × (6.6 cm)²
area = 136.8 cm²

(a-1)+(b+3)i = 5+8i
please answer me quickly i need it please
Answer:
a = 6, b = 5
Step-by-step explanation:
Assuming you require to find the values of a and b
Given
(a - 1) + (b + 3)i = 5 + 8i
Equate the real and imaginary parts on both sides , that is
a - 1 = 5 ( add 1 to both sides )
a = 6
and
b + 3 = 8 ( subtract 3 from both sides )
b = 5
