Answer:
Step-by-step explanation:
Write the equation of the line that has a slope of 3 and passes through (5, 11)
y = 3x - 26
y = 3x - 38
y = 3x - 4
x = 3y - 4
Answer:
3x-4
Step-by-step explanation:
y=ax+b general type of the line
a is the slope
y=3x+b
put 5 instead of the x and put 11 instead of the y
11=15+b
b=(-4)
Equation is 3x-4
Determine if the two lines y = 2x - 3/2 and y = -2x + 2/3 are parallel, perpendicular or neither. Explain
Answer:
Neither
Step-by-step explanation:
For two lines to be parallel, they must have the same slope. 2 and -2 are not the same. For lines to be perpendicular, their slopes must be negative reciprocals (ex 5 and -1/5) The slopes of these lines are not the same or negative reciprocals, so they are not parallel or perpendicular.

joyce traveled at an average speed of 60 miles per hour for 4.5 hours and then traveled at an average speed of 35 miles per hour for 1.5 hours. What was the total distance in miles that joyce traveled during this time ?
Answer:
322 1/2 miles
Step-by-step explanation:
Recall how s = d/t ; speed = distance/time.
To effectively solve for distance traveled, rearrange the formula so that distance is on the left-hand side by multiplying speed, and time.
speed × time = distance/time × time
speed × time = distance
distance = speed × time ; d = st.
Now to find the total distance traveled, individually multiply the rate of speed with the time. Time will cancel, and we will get the total mileage.
Given an average speed of 60 mph at a certain time for 4.5 hours, and another average speed of 35 mph at another time of 1.5. Calculate the distance individually, and then add both distances together. Distance 1 = 60 mph × 4.5 h = 60 miles / h × 4.5h = 60 miles × 4.5 = 270 miles.
Distance 2 = 35mph × 1.5h = 35 miles / h × 1.5h = 35 miles × 1.5 = 52 1/2 miles.
Distance 1 + Distance 2 = Total distance.
270 miles + 52 1/2 miles = 322 1/2 miles.
3. In the figure shown, a circle with center O and radius of length 3 units is
inscribed in a square. What is the area of the shaded region? *
A. 3.86 square units
B. 7.73 square units
C. 28.27 square units
D. 32.86 square units
Answer:
C
Step-by-step explanation:
To find the area of a circle, take its radius (3) and square it. In this case, 3 times 3 = 9. Then, you multiply the answer by pi, which rounds to 3.14, but is more like 3.14159265......etc, etc. There is a rhyme for that: May I have a large container of coffee beans? Where the length of each word is a number of pi. Anyway, most people would write 9pi, but this is asking for the exact answer, so you can do 3.14 times 9, which equals roughly 28.27. Hope this helped!

Carbon-14 is a radioactive isotope that has a half-life of 5,730 years. Approximately how many years will it take for carbon-14 to decay to 10 percent of its original amount?
Answer:
Carbon-14 will take 19,035 years to decay to 10 percent.
Step-by-step explanation:
Exponential Decay Function
A radioactive half-life refers to the amount of time it takes for half of the original isotope to decay.
An exponential decay can be described by the following formula:
[tex]N(t)=N_{0}e^{-\lambda t}[/tex]
Where:
No = The quantity of the substance that will decay.
N(t) = The quantity that still remains and has not yet decayed after a time t
[tex]\lambda[/tex] = The decay constant.
One important parameter related to radioactive decay is the half-life:
[tex]\displaystyle t_{1/2}=\frac {\ln(2)}{\lambda }[/tex]
If we know the value of the half-life, we can calculate the decay constant:
[tex]\displaystyle \lambda=\frac {\ln(2)}{ t_{1/2}}[/tex]
Carbon-14 has a half-life of 5,730 years, thus:
[tex]\displaystyle \lambda=\frac {\ln(2)}{ 5,730}[/tex]
[tex]\lambda=0.00012097[/tex]
The equation of the remaining quantity of Carbon-14 is:
[tex]N(t)=N_{0}e^{-0.00012097\cdot t}[/tex]
We need to calculate the time required for the original amout to reach 10%, thus N(t)=0.10No
[tex]0.10N_o=N_{0}e^{-0.00012097\cdot t}[/tex]
Simplifying:
[tex]0.10=e^{-0.00012097\cdot t}[/tex]
Taking logarithms:
[tex]ln 0.10=-0.00012097\cdot t[/tex]
Solving for t:
[tex]\displaystyle t=\frac{log 0.10}{-0.00012097}[/tex]
[tex]t\approx 19,035\ years[/tex]
Carbon-14 will take 19,035 years to decay to 10 percent.
Answer:
19,035 years

This week, 957 people went to the beach. Last week, 1,207 people went to the beach. The number of people who went to the beach fell by what percent? Use pencil and paper. Explain how you know whether the answer is greater than or less than 25%
Answer:
Less than 25%
Step-by-step explanation:
1. Find the difference of the two numbers: 1,207 - 957 = 250
decrease = original number - new number
2. Then, divide the decrease by the original number
250/1,207 = 0.207
3. Multiply the answer by 100 to get the percentage
0.207 x 100 = 20.7%
Therefore, the number of people fell by 20.7%
Hence, the answer is less than 25%

Write an equation of the line that passes through (3, 4) and is perpendicular to the line
that passes through y = -1x +7.
f(x)=4x^2+5x-3
g(x)=4x^3-3x^2+5
Find (f-g)(x)
Answer:
For me the answer was (f+g)(x)=4x^3+x^2+5x+2
Step-by-step explanation:
A function assigns the values. The value of the (f-g)(x) is 4x³ + x² +2 is 4x³ + x² + 5x + 2.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given that f(x)=4x²+5x-3 and g(x)=4x³-3x²+5, therefore, the value of the (f-g)(x) can be written as,
(f-g)(x) = f(x) - g(x)
= 4x² + 5x - 3 + 4x³ - 3x² + 5
= 4x³ + 4x² - 3x² + 5x + 5 - 3
= 4x³ + x² +2
Hence, The value of the (f-g)(x) is 4x³ + x² +2 is 4x³ + x² + 5x + 2.

Answer:
D. a║b, because if two lines are perpendicular to the same line, then they are parallel to each other.
Step-by-step explanation:
This is more of a rule than anything else, but to prove this, you can think of c as the transversal. The 4 angles at the intersection of line a and line c are 90 degrees, and so are the 4 angles at the intersection of line b and line c. Using the converses of the Corresponding Angles Theorem, Same Side Interior Angles Theorem, Alternate Interior Angles Theorem, etc.., you can prove that a and b are parallel.

Eloise is baking cupcakes and cookies for a birthday party. He baked 2.5 times as many cookies as cupcakes for a total of 56 items. How many of each item did she bake?
A. 16 cookies and 40 cupcakes
B. 35 cookies and 21 cupcakes
C. 35 cupcakes and 21 cookies
D. 16 cupcakes and 40 cookies
Answer:
D 16 cupcakes and 40 cookies
Step-by-step explanation:
I wrote an equation to solve for this
2.5x + x = 56
x represents cupcakes
3.5x = 56
x = 16
16 represents cupcakes.
16*2.5 = 40 (cookies)
6% - 18 = 4(2x - 3) - (2x + 6)
Answer: x = 5.2425

 situation 1: kayla has $30 to spend on yogurt. She spent a total of $6 each day on yogurt.
in situation 1, which role model is the total amount that Kayla has left to spend on yogurt (c) as a function of the numbers of days (d)
A) c=30-6d
B) c=30+6d
C) d=30-6c
D) c=6d-30
Answer:
A
Step-by-step explanation:
Kayla spends 6 a day and has a total of 30 dollars, c is the amount left over so this would make the equation c=30-6d
The correct statement will be;
⇒ c = 30 - 6d
Where, 'c' is left amount and 'd' is number of days.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Kayla has $30 to spend on yogurt.
And, She spent a total of $6 each day on yogurt.
Now,
Let 'c' is left amount and 'd' is number of days.
And, She spent a total of $6 each day on yogurt.
So, We can formulate;
⇒ c = 30 - 6d
Where, 'c' is left amount and 'd' is number of days.
Thus, The correct statement will be;
⇒ c = 30 - 6d
Where, 'c' is left amount and 'd' is number of days.
