Sophie invested 5,000 into an account that will increase in value by 2.3% each year. Write a function to model this situation, then find the value of the investment after 15 years
Answer:
$6725
Step-by-step explanation:
Given data
Princiapal= $5000
Rate=2.3%
Time= 15years
The function that will model this situation is given as
A=P(1+rt)
The above function is a simple interest function
Substitute our data we can find the amount A
A=5000(1+0.023*15)
A= 5000(1+0.345)
A=5000(1.345)
A=5000*1.345
A=$6725
Hence the value of the investment after 15 years is $6725

0 is the multiplicative inverse of 0?
Answer:
false
Step-by-step explanation:
I say false because the multiplicative inverse of 0 is undefined and the multiplicative inverse tells us that when you multiply a number by its inverse the product will be1 think the multiplicative inverse of 0 is undefined.

Solve the exponential equation
Solve exponential equation 1/16=64^4x-3
Answer:
x = 7/12
Step-by-step explanation:
Solve the exponential problem :
1/16=64^4x-3
1 / 4^2 = 4^3(4x - 3)
4^-2 = 4^3(4x - 3)
-2 = 3(4x - 3)
-2 = 12x - 9
-2 + 9 = 12x
7 = 12x
7/12 = 12x/12
7/12 = x
Hence, x = 7/12
Answer is 7/12, or approx. 0.58333... Answer explained in attached file.

According to the American Academy of Ophthalmology, 25% of Americans have brown irises. A random survey of students at a local community college found that 58 out of 175 had brown irises. What is the test statistic (ie the Z score) for this sample of students
Answer:
2.49
Step-by-step explanation:
Given X= 58
N = 175.
P = 25% = 0.25.
[tex]P' = \frac{X}{N} = \frac{58}{175} = 0.3314\\Z = \frac{P'-P}{\sqrt{\frac{pq}{N} } }[/tex]
Now plugging the values we get
[tex]= \frac{0.3314-0.25}{\sqrt{\frac{0.25\times0.75}{175} } }[/tex]
=2.49

give 4 rational number between 1/2 and 3/4
Answer:
11/20
3/5
7/10
13/20
Step-by-step explanation:
A rational number is a number that can be derived by dividing 2 whole numbers
1/2 = 0.5 0r 50%
3/4 = 0.75 75%
Between 50% and 75% are 51 - 74 which can be expressed as rational numbers
3/5 = 0.6
7/10 = 0.7
11/20 = 0.55
13/20 = 0.65

Answer:
the slope is 1 so D
Step-by-step explanation:
Answer:
D.1
Step-by-step explanation:
Hello There!
Given two points we can use the slope formula to identify the slope
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Where the x and y values derive from the points given
So all we have to do is plug in the x and y values from the given points
so
slope =
[tex]\frac{8-3}{3-(-2)} \\8-3=5\\3-(2)=5\\\frac{5}{5} =1[/tex]
So we can conclude that the answer is D. 1
The length of a rectangle is one less than twice its width. The area is 66 square centimeters. Find the length and width.
Answer:
I. Length, L = 11 cm
II. Width, W = 6 cm
Step-by-step explanation:
Let the length of the rectangle be L.
Let the width of the rectangle be W.
Given the following data;
Area of rectangle = 66 cm²
Translating the word problem into an algebraic expression, we have;
L = 2W - 1 .....equation 1
We know that the area of a rectangle is given by the formula;
A = L * W
Substituting
66 = L * W ....equation 2
Substituting eqn 1 into eqn 2, we have;
66 = (2W - 1) * W
66 = 2W² - W
2W² - W - 66 = 0
Note: the standard form of a quadratic equation is ax² + bx + c = 0
a = 2, b = -1 and c = -66
Solving the quadratic equation using the quadratic formula;
The quadratic equation formula is;
[tex] x = \frac {-b \; \pm \sqrt {b^{2} - 4ac}}{2a} [/tex]
Substituting into the equation, we have;
[tex] x = \frac {-(-1) \; \pm \sqrt {1^{2} - 4*2*(-66)}}{2*2} [/tex]
[tex] x = \frac {1 \pm \sqrt {1 - (-528)}}{4} [/tex]
[tex] x = \frac {1 \pm \sqrt {1 + 528}}{4} [/tex]
[tex] x = \frac {1 \pm \sqrt {529}}{4} [/tex]
[tex] x = \frac {1 \pm 23}{4} [/tex]
[tex] x_{1} = \frac {1 + 23}{4} [/tex]
[tex] x_{1} = \frac {24}{4} [/tex]
x1 = 6
We do not need the negative value of x, so we proceed.
Therefore, Width, W = x1 = 6 cm
Next, we find the length L;
From eqn 1;
L = 2W - 1
L = 2(6) - 1
L = 12 - 1
L = 11 cm

b) Find the equation of the trend line (line of best fit). Show your work. (2 points)
Answer:
Step 1:
Draw a graph - Put Customers on the x-axis and Tips on the y-axis
Equation of a line = mx + c
Then look for where the line crosses the x-axis (this is "c")
Choose two points and find the gradient using this formula:
Change in y/change in x
The number you just got is your "m"
Put it all together and you have y = Mx + C
