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)}

Answer:
in terms of pi: 112.5pi mm squared
substituting pi for 3.14: 353.25 mm squared
Step-by-step explanation:
Surface area cone equation:

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]

If f(x) is an exponential function where f(2)=23 and f(3)=58, then find the value of f(6), to the nearest hundredth.
The exponential function is given as 3.68 × (2.52)ˣ. Then the value of function at x = 6 will be 942.43.
What is an exponent?The exponent denotes that the base will rise to a specific level of strength. The base is X, and the power is n.
If f(x) is an exponential function where f(2) = 23 and f(3) = 58.
Then the exponential function will be
f(x) = abˣ
If f(2) = 23, then we have
23 = ab² ...1
If f(3) = 58, then we have
58 = ab³ ...2
Then from equations 1 and 2, we have
a = 3.62 and b = 2.52
Then the function will be
f(x) = 3.68 × (2.52)ˣ
Then the value of f(6) will be
f(6) = 3.68 × (2.52)⁶
f(6) = 3.68 × 256.1
f(6) = 942.43

Hi!
We can see the river is a straight line.
This means that the angles that fall upon it are supplementary angles, and will add up to 180 degrees.
Therefore:
[tex]x+2x+21=180[/tex]
Combine like terms:
[tex]3x+21=180[/tex]
Subtract 21 from both sides:
[tex]3x=159[/tex]
Divide both sides by 3:

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

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

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
