Answer:
f(x) = 4x - 1
Step-by-step explanation:
The answer to this question is f(x) = 4x - 1 because function notation displays the values of how the input of x yields the output of y. This means that in this form, y is changed to the x input where the substitution of the x in the equation yields the new y.

Step-by-step explanation:
find the measure of each interior angle of a regular polygon with the following number of sides 12
Answer:
each interior angle = 150°
Step-by-step explanation:
(N x 180°) - 360° = the sum of interior angles
where N = the number of sides
(12 x 180°) - 360° = 1800°
Since it is a regular polygon, all 12 angles are equal:
1800°/12 = 150°

Answer:
Zeroes are x = 6 and x = -4
Factored form is - ( x + 4 ) ( x - 6 )
Standard form is -x^2 + 2x +24
Step-by-step explanation:
Solve out the equation to get the standard form, then factor that equation to get the factored form. Set each factor equal to zero and solve for x to get zeroes of the function

The length of a planet's orbit around a star is approximately 22,200,000 km.
It takes the planet about 1230 Earth days to complete a full orbit.
What is the planet's average speed in kmh-1 to 3sf?
Answer:
Speed = 7520 km/h
Step-by-step explanation:
Given the following data;
Distance = 22,200,000 km.
Time = 1230 Earth days
To find the average speed of the planet;
First of all, we would have to convert the time in Earth days to hours;
1 Earth day = 24 hours
1230 Earth day = x
Cross-multiplying, we have;
x = 1230 * 24
x = 29520 hours
Therefore, time = 29520 hours
Substituting into the formula, we have;
Speed = 22200000/29520
Speed = 7520.325 km/h
To 3 significant figures;
Speed = 7520 km/h
Solve for the surface area of the figure below..
Answer and Step-by-step explanation:
To find the surface area, we have to find the area of all the faces of the shape, then add them together. We also only use the exposed faces, or the faces on the outside, not the inside.
Lets start with the rectangular prismed shape.
We have two faces with sides of 4 and 5, two faces with sides 16 and 4, and 1 side with 16 and 5.
Rectangles:
4 × 5 = 20
4 × 5 = 20
4 × 16 = 64
4 × 16 = 64
5 × 16 = 80
Now, let's do the triangles up top. There will essentially be 4 triangles, because we split them in half to find the area.
They have side lengths of 6 and 8.
Triangles:
6 × 8 = 48
6 × 8 = 48
6 × 8 = 48
6 × 8 = 48
Now, we have to the two rectangles up top.
They have side lengths of 10 and 4.
Top Rectangles:
10 × 4 = 40
10 × 4 = 40
Now, we add them all together.
20 + 20 + 64 + 64 + 80 + 48 + 48 + 48 + 48 + 40 + 40 =
40 + 208 + 192 + 80 =
520.
The Surface Area of the figure is 520 [tex]m^2[/tex]

Suppose you invest $130 a month for 5 years into an account earning 8% compounded monthly. After 5 years, you leave the money, without making additional deposits, in the account for another 25 years. How much will you have in the end?
Answer:
FV= $70,887.15
Step-by-step explanation:
First, we need to calculate the future value of the $130 deposit for 5 years:
FV= {A*[(1+i)^n-1]}/i
A= monthly deposit= $130
i= 0.08/12= 0.0067
n= 5*12= 60 months
FV= {130*[(1.0067^60) - 1]} / 0.0067
FV= $9,561.96
Now, using the following formula, the future value of the investment after 25 years:
FV= PV*(1 + i)^n
n= 25*12= 300
FV= 9,561.96*(1.0067^300)
FV= $70,887.15

For purposes of making on-campus housing assignments, a college classifies its students as Priority A (seniors), Priority B (juniors), and Priority C (freshmen and sophomores). Of the students who choose to live on campus, 22% are seniors, 29% are juniors, and the rest are underclassmen. The most desirable dorm is the newly constructed Gold dorm, and 71% of the seniors elect to live there. 19% of the juniors also live there, along with only 5% of the freshmen and sophomores. What is the probability that a randomly selected resident of the Gold dorm is a senior? Show as much work as possible.
Answer:
The probability that a randomly selected resident of the Gold dorm is a senior is 0.1562
Step-by-step explanation:
The given percentage of each class of student is presented as follows;
Priority A (seniors) = 22%, ∴ P(s) = 0.22
Priority B (juniors) = 29%, ∴ P(j) = 0.29
Priority C (freshmen and sophomores) = (100 - 22 - 29)% = 49%, ∴ P(fs) = 0.49
The percentage of the seniors that elect to live at the Gold dorm, = 71%, ∴ P(sG) = 0.71
The percentage of the juniors that live at the Gold dorm = 19%, ∴ P(jG) = 0.19
The percentage of the freshmen and sophomores that live in the Gold dorm = 5%, ∴ P(fsG) = 0.05
The probability that a randomly selected resident of the Gold dorm is a senior = P(s∩sG) = P(s) × P(sG)
∴ P(s∩sG) = 0.22 × 0.71 = 0.1562
Therefore;
The probability that a randomly selected resident of the Gold dorm is a senior = P(s∩sG) = 0.1562.
At an assembly 7 out of the first 10 students who entered the gym were carrying a backpack.
Based on this information, if 700 students were at the assembly, how many students could be expected to be carrying a backpack?
Record your answer on the keypad and fill in the bubbles on your answer document. Be sure to use the correct place value.
Answer: 490
Step-by-step explanation: If 7 out of ten students have a backback you can also say 7/10. If in total there are 700 students we can multiply 7/10 or .7 woth 700 and get the answer. (7/10)(700)=490

A person invested $3,500 in an account growing at a rate allowing the money to double every 15 years. How long, to the nearest tenth of a year would it take for the value of the account to reach$7,700?
Answer:
30 years and a half
Step-by-step explanation:
well let's just say 3.5k x hmm 2? at an estimate and that will get us to 7000.. so in order to get to 7000 we have to wait 15 years which is 30 years and a half. From Xthermyx. A brainly user.
It would take 22.7 years for the value of the account to reach $7,700.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
Since the money in the account is doubling every 15 years.
The following equation is used to find the time it takes to reach a certain value:
t = (ln(P/F))/(ln(1+r))
where:
P = the initial investment amount
F = the future value we want to reach
r = the growth rate per period
ln = natural logarithm
t = the number of years it takes to reach F
P = $3,500
F = $7,700
r = ln(2)/15 (since the money is doubling every 15 years).
Plugging these values into the equation.
t = (ln(3500/7700)) / (ln(1+ln(2)/15))
t = ln (5/11) / ln (1 + 0.30/15)
t = 22.7
Therefore,
It would take 22.7 years for the value of the account to reach $7,700.

A car starts from rest and attains a velocity of 9km/h in 5 seconds . Calculate acceleration and the displacement covered in that time
Answer:
Acceleration is 0.5 m/s² and the distance covered is 6.25 m.
Step-by-step explanation:
Given that,
Initial speed, u = 0
Final speed, v = 9 km/h = 2.5 m/s
Time, t = 5 seconds
We need to find the acceleration and the displacement covered in that time. Acceleration = rate of change of velocity
So,
[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{2.5-0}{5}\\\\a=0.5\ m/s^2[/tex]
Distance d can be calculated using third equation of motion.
[tex]d=\dfrac{v^2-u^2}{2a}\\\\d=\dfrac{2.5^2-0^2}{2\times 0.5}\\\\d=6.25\ m[/tex]
So, acceleration is 0.5 m/s² and the distance covered is 6.25 m.
