Michael goes to the bank and puts $6000 in a savings account. He earns a simple interest of 3.5% If he leaves the money in the account for 2 years, what is the total amount in the account after the two years?
9514 1404 393
Answer:
$6420
Step-by-step explanation:
The account value can be found using the formula ...
A = P(1 +rt)
where P is the initial deposit, r is the annual rate, and t is the number of years.
A = $6000(1 + .035×2) = $6000(1.07) = $6420
The total amount after 2 years is $6420.
What is the length of the line TR
Answer:

Answer:
23 3/4
Step-by-step explanation
f(x)=5x-25/4 is a linear equation, and because of that its domain includes all real numbers, including 6. The corresponding number in the range is then f(6) = 5(6) - 6 1/4 = 30 - 6 1/4 = 23 3/4

I’m trying to figure out the domain and range of this, could someone explain and give the answer? Thank you
Answer:
The domain is all the possible inputs for this function. The range is all the possible outputs for this function.
The line starts at the x-value of 0 and ends at the x-value of 12. Therefore, your domain is D: [0, 12].
The line starts at the y-value of 9000 and ends at the y-value of 0. Therefore, your range is R: [0, 9000].

Sam's mother is twice as old as sam, In 12 years, Sam will be as old as his mother was 12 years ago. How old are is sam and his mother now?
Answer:
Sam is 24 years old and his mom is 48 years old
Step-by-step explanation:
;)
The present age of Sam is 24 years and the present age of Sam's mother is 48 years
Let the present age of Sam's mother = M
Let the present age of Sam = S
Sam's mother is twice as old as Sam so we can write
[tex]\rm M = 2S.........(1)\\[/tex]
12 years ago the age of Sam's mother = M - 12
After 12 years the age of Sam = S + 12
According to the given condition
[tex]\rm S + 12 = M-12 ......(2)[/tex]
From equations (1) and (2) solving for M and S we get
[tex]\rm S + 12 = 2S -12\\S = 24\\M = 2\times S = 2\times 24 = 48[/tex]
So we can conclude that the present age of Sam is 24 years and the present age of Sam's mother is 48 years.

Here is a probability scale:
A B C
D
1
O
a)
Which letter shows the probability of choosing a yellow sweet?
W
b)
Which letter shows the probability of choosing a sweet that is not orange?
Answer: B and D
Step-by-step explanation:
Given
There are 4 red, 2 Green, 3 Yellow, and 1 purple sweet i.e. total of 10 sweets
(a)No of yellow sweet =3
Probability
[tex]P=\dfrac{\text{No of yellow sweets}}{\text{Total no of sweets}}=\frac{3}{10}\\P=0.3[/tex]
In number line, A, B, and C represent 0.2,0.3 and 0.4
For yellow it is B
(b)sweet that is not orange is red, green, yellow, and purple
So, probability
[tex]P=\dfrac{\text{sweet that is not orange}}{\text{Total sweets}}=\frac{10}{10}=1[/tex]
So, D represents it
The base of the isosceles triangle is parallel to x -axis and has
both end-points on the parabola [tex]y =x(10-x)[/tex]and its vertex
belongs to the x -axis. Find area of the triangle if the length of its
base is 8.
Answer:
36 square units
Step-by-step explanation:
y = x(10-x)
This is a down-opening parabola with axis of symmetry x = 5
Vertex of triangle (5,0)
Base of triangle is the horizontal chord of length 8, endpoints x = (1,9) and (9,9).
Height of triangle = 9
Area of triangle = ½·8·9 = 36 square units
List the key features of the quadratic equation y = x2 + 6x - 16.
A. x-intercepts: (-8,0) and (2,0), y-intercept: (0,–16), vertex: (-3,-25).
B. X-intercepts: (-8,0) and (2,0), y-intercept: (0,–6), vertex (-3,-25).
C. X-intercepts: (8,0) and (-2,0), y-intercept: (0.-16), vertex: (-3,-25).
D. x-intercepts: (-8,0) and (2,0), y-intercept: (0,16), vertex: (-3,-25).
Answer:
Correct choice is A
Step-by-step explanation:
Quadratic Function
The vertex form of the quadratic function has the following equation:
[tex]y=a(x-h)^2+k[/tex]
Where (h, k) is the vertex of the parabola that results when plotting the function, and a is a coefficient different from zero.
The x-intercepts are the points where the graph of the function crosses the x-axis, they are also called zeros or roots. They can be found by solving the equation y=0,
The y-intercepts are the points where the graph of the function crosses the y-axis. They can be found by setting x=0.
We are given the function:
[tex]y = f(x)=x^2+6x-16[/tex]
Find the y-intercept. x=0:
[tex]f(0)=0^2+6*0-16=-16[/tex]
y-intercept: (0,-16)
Find the x-intercepts, y=0. Solve the equation
[tex]x^2+6x-16=0[/tex]
Factoring:
[tex](x-2)(x+8)=0[/tex]
Which gives x=2, x=-8.
X-intercepts (2,0) (-8,0)
This leaves us only choice A as correct. But we'll compute the vertex also.
Completing squares:
[tex]y=x^2+6x-16=x^2+6x+9-16-9=(x+3)^2-25[/tex]
Comparing with the vertex form of the function, we have: h=-3, k=-25, thus the vertex is located at (-3,-25)
This confirms that the correct choice is A
Write the numerator of a fraction equivalent to 3/4 that has a denominator of 20
Answer:
15
Step-by-step explanation:
Cross multiply
3 times 20 = 60
4 times x = 4x
now your left with
60= 4x
divide 4 on both sides
15 = x
The numerator of a fraction equivalent to 3/4 that has a denominator of 20 is 15.
A fraction is made up of a numerator and a denominator. Examples of fraction are: [tex]\frac{3}{4} , \frac{1}{2}[/tex]. The numerators are 3 and 1. The denominators are 4 and 2.
In order to determine the numerator, we have to determine the relationship between the two denominators given ( 20 and 4). 20 is a multiple of 4. 20 / 4 = 5. The second step is to multiply 3 by 5 = 3 x 5 = 15.

This graph shows the solution to which inequality?

O A. yz 1 / 8x - 2
O B. ysx-2
O c. y> 1/3x-2
Answer:
[tex]y > \frac{1}{3}x - 2[/tex]
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope, and b is the y-intercept(value of y when x = 0).
In this question:
We have that when [tex]x = 0, y = -2[/tex]. So the line is given by:
[tex]y = mx - 2[/tex]
Finding the slope:
We have two points in the line, which are (-3,-3) and (3,-1). The slope is given by the change in y divided by the change in x. So
Change in y: -1 - (-3) = -1 + 3 = 2
Change in x: 3 - (-3) = 3 + 3 = 6
Slope: [tex]m = \frac{2}{6} = \frac{1}{3}[/tex]
Solution to the inequality:
The solution to this inequality is all the points above the dashed line, which means that the dashed line is not part of the solution. So
[tex]y > \frac{1}{3}x - 2[/tex]
