3. Write an exponential equation for each coin that will give the coin's value, V, at any time, t. Use the formula:
V(t) = P(1 + r)t, where V(t) is the value of the coin in t years, P is the initial investment, and r is the growth rate.
Coin A worth $25 and increase by 7% each year and coin B worth $40 increase by 5% each year
9514 1404 393
Answer:
V(t) = 25(1.07^t)V(t) = 40(1.05^t)Step-by-step explanation:
Put the given numbers into the given formula. It can be simplified a little bit.
Formula:
V(t) = P(1 + r)^t
Coin A
P = 25, r = .07
V(t) = 25(1.07^t)
Coin B
P = 40, r = 0.05
V(t) = 40(1.05^t)

There are 6 yellow hexagons 2 red trapezoids and 9 green triangles how many flowers could you make if they were changed 30 yellow hexagons 50 red trapezoids and 60 green triangles. Which shape would you have left over the most
Answer:
a) 5 flowersb) TrapezoidStep-by-step explanation:
For one flower, the following shapes are used;
6 yellow hexagons, 2 red trapezoids and 9 green triangles
If we are given 30 yellow hexagons 50 red trapezoids and 60 green triangles, to get the number of flowers we can make, we will find the greatest common factor of 30, 50 and 60
30 = 6*5
50 = (2*5)+40
60 = (9*5)+15
We can see that 5 is common to all the factors. This means that we can make 5 flowers if they were changed to 30 yellow hexagons 50 red trapezoids and 60 green triangles.
Since there are 40 trapezoids left and 15 green triangles left, hence the shape that would have n as left over most is trapezoid (40 left over)

The area of the base of a rectangular prism is 24 square centimeters and the height is 12 centimeters. What is the volume of the rectangular prism in cubic centimeters?
Answer:
V = 288 cm³
Step-by-step explanation:
Given that,
The area of the base of a rectangular prism is 24 square centimeters and the height is 12 centimeters.
We need to find the volume of the rectangular prism. For a rectangular prism, the volume is given by :
V = lbh
Since, lb = A, area of the prism
V = Ah
V = 24 × 12
= 288 cm³
So, the volume of the rectangular prism is 288 cm³.

2.
A) 12
C) -11
B) 10
D) 6
Answer:
A
Step-by-step explanation:
Since the 2 legs are congruent then the triangle is isosceles and therefore the base angles are congruent, that is
∠ 2 = [tex]\frac{180-120}{2}[/tex] = [tex]\frac{60}{2}[/tex] = 30° , thus
3x - 6 = 30 ( add 6 to both sides )
3x = 36 ( divide both sides by 3 )
x = 12 → A
What is the value of this expression when a=3 and b= -2? (3a (exponent) -2 b (exponent) 6) exp. -2 ___________________________ (2a (exponent) -1 b (exponent) 5) Its all one equation!
Answer:
I looked online to find the equation well written, but i could not find it, so i will guess that the equation is:
[tex]\frac{3*a^{-2} - 2*b^{-6}*e^{-2}}{2*a^{-1}*b^{5}}[/tex]
Now we want to find the value of this equation when:
a = 3 and b = -2
So we can just replace these values in the equation, each a is replaced by a 3, and each b is replaced by a -2.
The equation becomes.
[tex]\frac{3*3^{-2} - 2*(-2)^{-6}*e^{-2}}{2*3^{-1}*(-2)^{5}} = 44.3[/tex]

Mr. Boyd completed a 3.19 mile walk/ run. For every 5 minutes of walking, he ran for 1.5 minutes. If he completed his workout in 48:52 minutes, how much of that time was spent running?
Answer:
He spent 11.25 minutes running
Step-by-step explanation:
Mr. Boyd completed a 3.19 mile walk/ run.
For every 5 minutes of walking, he ran for 1.5 minutes.
He completed his workout in 48.52 minutes.
Hence, we have the equation:
1.5x + 5x = 48.52 minutes
6.5x = 48.52 minutes
x = 48.52/6.5
x = 7.4646153846
Approximately = 7.5 minutes
Therefore the time spent running = 1.5 × 7.5 minutes
= 11.25 mimutes

The second picture represents the addition of two vectors u and v by the parallelogram method for vector addition.
What is a vector?It is defined as the quantity that has magnitude as well as direction also the vector always follows the sum triangle law.
We have:
Two vectors u and v
The resultant vector will be u + v
As we know, in the parallelogram method for vector addition
We have to place two vectors at the same starting point.
Then complete the parallelogram.
The diagonal of the parallelogram represents the addition of the vector.
Thus, the second picture represents the addition of two vectors u and v by the parallelogram method for vector addition.

How do you find the markup rate?
Answer: Simply take the sales price minus the unit cost, and divide that number by the unit cost. Then, multiply by 100 to determine the markup percentage. For example, if your product costs $50 to make and the selling price is $75, then the markup percentage would be 50%.
Step-by-step explanation:
Answer:
hope this helps!
Step-by-step explanation:
Divide the amount added to the price by the amount the item costs you to buy to find the markup rate expressed as a decimal. In this example, you would divide $2 by $6 to get 0.3333. Convert the markup rate expressed as a decimal to a markup rate expressed as a percentage by multiplying it by 100.
