A straight line passes through the origin and has a gradient of 4. Find the equation
Answer:
y = 4x
Step-by-step explanation:
The slope is 4.
The line passes through (0, 0).
Equation of a line y = mx + b, m is the slope, and b is the y-intercept.
y = 4x + b
Put x and y as 0.
0 = 4(0) + b
0 = b
The y-intercept is 0.
The equation of the line is y = 4x.
Please explain how you would prove that all circles are similar?
Answer:
Shapes are similar when one can be scaled to be like another one. Circles are always the same shape and they only vary in size. A very small circle can be expanded to be the same size as any other without changing it's shape, only size. However this is not true for ovals since they come in different shapes.
Step-by-step explanation:
In a plane, line e is perpendicular to line f, line f is perpendicular to line g, and line h is parallel to line f. which of the following must be true?

then line h is perpendicular to line g.
Which of these graphs represents a function?
Answer:
first and second
Step-by-step explanation:
the last 2 have angles wich make that value given by several numbers
Step-by-step explanation: Here were given 4 relations in the form of graphs and were asked to determine which one represents a function.
In this situation, we would use what is called the vertical line test.
In other words, if we can draw a vertical line that passes through
more than one point on the graph, then the relation is not a function.
Notice that in this problem, every vertical line draw on a
graph passes through more than 1 point except for W.
So W represents a function.
The radius of the large sphere is double the radius of
the small sphere.
How many times is the volume of the large sphere than
the small sphere?
2
4
6
8
Answer:
8 times
Step-by-step explanation:
Volume of sphere 4/3 *pi*r^3
Let small sphere radius r1=r
So radius of large sphere R= 2r (given)
Put all valves in sphere formula and calculate
Small sphere vol v1 = 4/3*pi*r^3......... Let assume eq 1
Large sphere vol= 4/3*pi*(2r)^3
= 4/3*pi* 8r^3
Or = 8v1
substitute 4/3*pi*r^3 value from eq1
Answer:
8
Step-by-step explanation:
Given the ratio of the radii = a : b, then
ratio of volume = a³ : b³
Here the ratio of radii = 1 : 2 , thus
ratio of volume = 1³ : 2³ = 1 : 8
That is the volume of the larger sphere is 8 times the volume of smaller sphere.
Samir spins a fair coin and records the results. In the first four spins ‘Heads' comes up each time. Samir says, ‘A head is more likely than a tail'. Is he correct? YES/ NO Give a reason for your answer.
Answer:
No
Step-by-step explanation:
A coin has two sides which is the "Head" or the "tail". When a coin is tossed, since it only has two sides, one of either sides can come up because they both have 50-50 chance. The probability of having heads or tails is 0.5 or ½ and either side can come up.
Mathematically,
½ × ½ × ½ × ½ = ¹/₁₆
The probability of getting heads four times in a row when the coin is tossed is ¹/₁₆.
Solve for x.

x-6 = 15
Add 6 to each side
x-6+6 = 15+6
x = 21
Monica has $20. She needs to buy a gallon of milk that costs $2.50. She also wants to buy yogurt, which costs $1.20 a cup. What is the greatest number of cups of yogurt Monica can buy?
Answer: The greatest number of cups of yogurt MOnica can buy is 14.
Step-by-step explanation:
If she need to buy a gallon of milk then it means that $2.50 will be deducted from the money .
Use the the inequality to solve for how many cups of yogurt Monica can buy
1.20x + 2.50 ≤ 20
-2.50 2.50
1.20x ≤ 17.5
x≤14.5833...
which means the greatest number of cups of yogurt Monica can buy is 14.

Step-by-step explanation:
After graduating, Sallie Handshake’s best job offer will either be with a Big-8 accounting firm for $160,000 a year or as a State Farm agent in Grand Rapids, Michigan, for $40,000 a year. She can increase the probability of the former outcome by studying more, but such studying has its costs. If S represents her amount of studying (where S = 0 is no study and S = 1 is all-out effort), her probability of getting the job with a Big-8 firm just equals S. Her utility depends on how hard she studies and her subsequent annual income Y. She tries to maximize the expected value of the von Neuman-Morgenstern utility function U(S, Y) = Y1/2 − 400S2. If she chooses S to maximize her expected utility, how much will she study?
Answer:
The answer is "S=0.25"
Step-by-step explanation:
Given:
firm value= $160,000
time= $40,000 per year
s=0 to 1
function U(S, Y) = Y1/2 − 400S2
by solve the given value it will gives the study time that is:
S=0.25 that's why it is correct.

Trevor asks his bank for a loan of $22000 to add a guest
room to his house. His bank offers financing at 7.25%
compounded monthly, for a term of 5 years, payable
monthly. What is Trevor's monthly payment?
Answer:
$526.3 is the monthly payment
Step-by-step explanation:
We use the compound interest formula to calculate the total amount payable on the loan.
Mathematically;
A = P(1 + r/n)^nt
Where A is the amount to pay
P is amount borrowed = 22,000
r is interest rate = 7.25/100 = 0.0725
t is years = 5 years
n is the number of times we compound lee year = 12 times since it’s monthly
Substituting these values, we have
A = 22,000(1 + 0.0725/12)^(12)(5)
A = 22,000(1 + 0.006041666666667)^60
A = $31,578
Monthly payment is total amount/ number of months
There are sixty months in 5 years
So monthly payment is 31578/60 = $526.3

Instructions: Write the explicit rule. Remember to simplify and do not put spaces in your answer. Sequence: 30,0,−30,−60,… 30 , 0 , − 30 , − 60 , … = a n = Answer
Answer:
a(n)=60-30n
Step-by-step explanation:
Equation to use:
a(n) = a(1) + d(n-1)
where a(1) is the first term, d is the common difference between terms, and n is the nth term you are trying to find.
In this case, a(1) is 30, d is -30, and n is just n.
If you plug that into the equation and use the distributive property, you would get: a(n) = 30 -30n + 30.
Adding the two 30's gets you: a(n) = 60 - 30n, which is the solution.

Answer:
36.00 units
Step-by-step explanation:
Lengths of horizontal and vertical segments are easily determined by subtracting coordinates or counting grid squares:
ST = 6 -1 = 5
TR = 5 -(-1) = 6
IP = 1 -(-6) = 7
PE = 2 -(-3) = 5
The lengths of the diagonal segments are found using the Pythagorean theorem. Those lengths are the root of the sum of the squares of the rise and run. As before, you can determine those from counting squares or subtracting coordinates.
RI = √(2^2 +5^2) = √29 ≈ 5.385
ES = √(3^2 +7^2) = √58 ≈ 7.616
Then the perimeter is the sum of segment lengths:
Perimeter = ST +TR +RI +IP +PE +ES
= 5 + 6 + 5.385 +7 +5 +7.616 = 36.001
Rounded to hundredths, the perimeter is 36.00 units.

Answer: Part 1: 111.24
Part 2: 9.27
Part 3: 54 minutes
Step-by-step explanation:
Part 1: Since you already know that the total bill increases by 3%, you just have to find 103% of 180.
1.03*108= 111.24; your answer would be 111.24 pounds
Part 2: Since you already know yearly, 111.24 divided by 12= 9.27 per month
Part 3: First find 73% of 200 which is 146. Then subtract that from 200 which is 54. So you have 54 minutes left.

The table represents the function f(x). A 2-column table with 7 rows. The first column is labeled x with entries negative 3, negative 2, negative 1, 0, 1, 2, 3. The second column is labeled f of x with entries negative 9, negative 6, negative 3, 0, 3, 6, 9. What is f(3)
Answer:
9
Step-by-step explanation:
Okay, here we have a table with the x and y columns
What we are to find is F(3)
Now this is obtainable from the table
The term f(x) equals values in the table y
We can obtain the values of y from the equation linking x to y
Now the term f(3) can be obtained by checking the value of y or f(x) that corresponds to the value 3
We can see that it is the last term on the x side that can give the value of y we are looking for
So without much further ado we can see that it is the last value on the table y we are also looking at
This equals 9
So F(3) = 9
Answer:
9
Step-by-step explanation:
Hope this helps
