Answer:

V(t)=28,000(0.75)^t.

$8859.375

Step-by-step explanation:

Please find the attachment for the function.

We have been given that a car sells for $28,000.The car  depreciates such that each year it is worth 3/4 of its value from the previous year. We are asked to find the model for the value V of the car after t years.

We know that an exponential function is in form y=a(b)^x, where,

a = Initial value,

b = Growth or depreciation rate.

Since each year the car worth 3/4 of its value from the previous year, so its value is depreciating and b=\frac{3}{4}=0.75.

Therefore, our required function would be V(t)=28,000(0.75)^t.

To find the value of car after 4 years, we need to substitute t=4 in our function as:

V(4)=28,000(0.75)^4

V(4)=28,000(0.31640625)

V(4)=8859.375

Therefore, the value of the car after 4 years would be $8859.375.

The volume of a medal is 35 cm³
ratelena [41]

Answer:

301.224 g

Step-by-step explanation:

Let's divide in the ratio 21:4 the volume of the medal (35cm^3)

copper = (21/25)(35cm^3) = 29.4cm^3

tin = (35 - 29.4)cm^3 = 5.6cm^3

<em>FOR THE COPPER</em>

8.84 : 1 = X : 29.4

X = 259.896(g)

<em>FOR THE TIN</em>

7.38 : 1 = X : 5.6

X = 41.328(g)

<em>(259.896 + 41.328)g </em><em>=</em><em> 301.224 g</em>

Ibrahim wants to give each of his six friends 1 2/3 candy bars. How many candy bars does he need to buy?
denis-greek [22]

Answer:

10 candy bars

Step-by-step explanation:

Since each of his friends needs a candy bar, you need to multiply 6 and 1 ⅔ together.

First, convert 1 ⅔ into an improper fraction: this gives us ⁵⁄₃.

Next, multiply ⁶⁄₁ and ⁵⁄₃ together. To do this, you can visualize 6 as ⁶⁄₁ (which is the same thing). Now you have ⁶⁄₁ x ⁵⁄₃.

<u>Simplify:</u>

The 6 in the numerator and the 3 in the denominator cancel out. This gives us ²⁄₁ x ⁵⁄₁ , which is 2 x 5.

2 x 5 = 10

Which rectangle if translated 12 units down and 7 units right will result in rectangle E?
jek_recluse [69]
The correct answer would be rectangle 'D'.

If we looked at rectangle 'E' and moved it to the left by 7 units (every unit = 1 square on the grid), we would arrive at a point. From then, we can move upwards 12 units and arrive at rectangle 'D'.
