what is the y-intercept of the following function? How do you know?
f(x) = x^2 + 4x + 6
Answer:
The y-intercept is 6
Step-by-step explanation:
The y-intercept of a function is where the graph of an equation touches or crosses the vertical axis. This is usually the value of y when x = 0.
For this particular function, when x = 0 ⇒
f(0) = 0^2 + 4(0) + 6
= 0 + 0 + 6
= 6
Therefore, the y-intercept of this function is 6
Answer:
6
Step-by-step explanation:
the y-intercept is the last number of the equation
so because 6 is the last number, the y-intercept is 6

Tyrell has a bankruptcy on his credit report and therefore pays higher interest rates on his current loans. he calculates that the extra money he pays in additional interest each year, if invested at the rate of 2.5% for one year, could earn him simple interest totaling $300. how much does tyrell pay in additional interest each month? a. $90 b. $100 c. $1,000 d. $12,000 please select the best answer from the choices provided. a b c d
Based on the simple interest amount he could be making, and the rate of investment, Tyrell's additional interest per month is $1,000.
How much is Tyrell paying in additional interest?Assuming the additional interest that Tyrell is paying is x, the following formula can be used:
300 = (x × 2.5%) x 12 months
Solving gives:
300 = 0.025x × 12
0.025x = 300/12
x = 25 / 0.025
x = $1,000

the average of 21, 18, 16 and x is 20. what is the value of x?
Answer: 25
Step-by-step explanation:
21 + 18 +16 + X = 20×4
55 + X = 80
X = 80- 55
Answer:
21.75
Step-by-step explanation:
21- 16 = 5
5/2 2.5
16 + 2.5 or 21 - 2.5
18.5 - 18 = .5
1/2 times 1/2 =

Identify the coordinates of four points on the line with each given slope and y-intercept. slope = 2/3 and y-intercept = -5.........PLEASE ANSWER ASAP
The linear equation is y = (2/3)*x - 5, and the 4 points in the graph are:
{ (-1, -17/3), (0, -5), (1, -13/3), (2, -11/3)}
How to identify the points on the line?A linear equation written in the slope-intercept form is:
y = a*x + b
Where a is the slope and b is the y-intercept.
In this case, we have:
a = 2/3
b = -5
So our line is:
y = (2/3)*x - 5
To find the points, we need to evaluate the line in 4 different values of x.
We will use: x = -1, 0, 1, 2.
for x = -1 we have:
y = (2/3)*-1 - 5 = -2/3 - 5 = -17/3
So this gives the point (-1, -17/3).
for x = 0 we have:
y = (2/3)*0 - 5 = -5
So this gives the point (0, -5).
for x = 1 we have:
y = (2/3)*1 - 5 = -13/3
So this gives the point (1, -13/3).
for x = 2 we have:
y = (2/3)*2 - 5 = 4/3 - 15/3 = -11/3
So this gives the point (2, -11/3).
Then the 4 points are:
{ (-1, -17/3), (0, -5), (1, -13/3), (2, -11/3)}

A history class is comprised of 10 female and 8 male students. If the instructor of the class randomly chooses 14 students from the class for an oral exam, what is the probability that 8 female students and 6 male students will be selected? Round your answer to 3 decimal places.
Step-by-step explanation:
I assume that one a student is picked for an oral exam, the same student will not be picked again.
the total number of possibilities to pick 14 students out of 18 is C(18, 14) = 18!/(14! × (18-14)!) = 18!/(14! × 4!) =
= 18×17×16×15/(4×3×2) = 18×17×2×5 =
= 3,060
how many of these possibilities contain exactly 8 girls and 6 boys ?
so, we choose 8 out of the 10 girls, and 6 out of the 8 boys.
that means
C(10, 8) × C(8, 6) = 10!/(8! × 2) × 8!/(6! × 2) =
= 10×9/2 × 8×7/2 = 5×9 × 4×7 =
= 45 × 28 = 1,260
so, the probability to have 8 girls and 6 boys in a random selection of 14 students out of 18 is
1260/3060 = 21/51 = 7/17 = 0.411764706... ≈ 0.412

15. Find all polar coordinates of point P where P = ordered pair 9 comma negative pi divided by 5
If the polar coordinate of a point is (9, π/5). Then the cartesian coordiante will be (7.28, 5.29).
What is coordinate geometry?Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.
The polar coordimnate is given below.
P(9, π/5)
Then the cartesian coordinate will be
We know that the conversion of the polar coordinate to the cartesian coordinate.
(x, y) = (r cos θ, r sin θ)
Then we have
r = 9
θ = π/5
Then we have
x = 9 cos π/5
x = 7.28
y = 9 sin π/5
y = 5.29
Then the coordinate will be (7.28, 5.29).

Grace wants to find the probability of a family of 3 children having 2 boys and 1 girl. Use a tree diagram to list the possibilities and state the probability of 2 boys and 1 girl.
A) 3/8
B) 2/3
C) 5/8
D) 1/2
Answer:
Step-by-step explanation:
My approach was to draw out the probabilities, since we have 3 children, and we are looking for 2 boys and 1 girl, the probabilities can be Boy-Boy-Girl, Boy-Girl-Boy, and Girl-Boy-Boy. So a 2/3 chance if you think about it, your answer 2/3 can't be correct. If we assume that boys and girls are born with equal probability, then the probability to have two girls (and one boy) should be the same as the probability to have two boys and one girl. So you would have two cases with probability 2/3, giving an impossible 4/3 probability for both cases. Also, your list "Boy-Boy-Girl, Boy-Girl-Boy, and Girl-Boy-Boy" seems strange. All of those are 2 boys and 1 girl, so based on that list, you should get a 100 percent chance. But what about Boy-Girl-Girl, or Girl-Girl-Girl? You get 2/3 if you assume that adjacencies in the (ordered) list are important, i.e., "2 boys and a girl" means that the girl was not born between the boys.
The height of a ball kicked into the air from the ground can be approximated by the function
h=-5t^2 + 15t, where h is the
height in meters and t is the time in seconds.
Find the time it takes the ball to hit the ground. Show all work
Check the picture below, so that happens when h = 0.
[tex]\stackrel{h}{0}~~ = ~~-5t^2+15t\implies 0=-5t(t-3)\implies 0=t(t-3)\implies t= \begin{cases} 0\\ 3~\checkmark \end{cases}[/tex]
now, notice, 0 is also a solution, which means at 0 seconds the ball was touching the ground, well, it was kicked "from" the ground, so at 0 seconds it was initially on the ground anyway.

5. a) Among 72 students, 24 are selected to participate in music only, 26 are selected to participate in dance only and none of them participated in both activities. The rest of the students are selected in other activities. (i) How many students are participating in other than music or dance?
Answer
The students participating in other than music or dance = 22
Step by step explanation
Total number of students = 72
No. of students participating in dance = 26 (let them be 'a')
No. of students participating in music = 24 (let them be 'b')
No. of students participating in othe na than dance or music = 'c'
72 = a+b+c
= 26+24+c
= 50 + c
c (no. of students participating in other activities)
= 72 - 50 = 22
The volume of a beack ball is 905 square centimeters. Find the radius of the ball to the nearest whole number.
[tex]v = 905 \: {cm}^{3} [/tex]
to find:the radius of the given ball (sphere).
solution:[tex]r = \sqrt[3]{ \frac{3v}{4\pi} } [/tex]
[tex]r = \sqrt[3]{ \frac{3 \times 905}{4\pi} } [/tex]
[tex]r = 6 \: cm[/tex]
therefore, the radius of the ball is 6 cm.
note: refer to the picture I added on how you can change r as the subject of the formula.
[tex]r = (3 \frac{v}{4\pi} {)}^{ \frac{1}{3} } [/tex]
[tex]r = (3 \times \frac{905}{4 \times \pi} {)}^{ ^{ \frac{1}{3} } } [/tex]
[tex]r = 6.00049 \: cm[/tex]
[tex]r = 6 \: cm[/tex]
Hence, the radius of the beach ball is 6 centimeters.

What is x?
3(2x + 4) - 8x = -2(x + 1) + 3
50 points because I have a lot :/
Answer:
no solution
Step-by-step explanation:
Given equation:
3(2x + 4) - 8x = -2(x + 1) + 3
Expand the brackets:
⇒ 3(2x) + 3(4) - 8x = -2(x) - 2(1) + 3
⇒ 6x + 12 - 8x = -2x - 2 + 3
Collect like terms:
⇒ 6x - 8x + 12 = -2x - 2 + 3
Combine like terms:
⇒ -2x + 12 = -2x + 1
Subtract 12 from both sides:
⇒ -2x + 12 - 12 = -2x + 1 - 12
⇒ -2x = -2x - 11
Add 2x to both sides:
⇒ -2x + 2x = -2x +2x - 11
⇒ 0 = -11
The sides are not equal, therefore there is no solution
