Answer:
y= 4/3x - 8.7777777777(reoccurring)
Step-by-step explanation:
ok for perpendicular slopes we use the negative reciprocal of the original slope so -3/4 turns into 4/3. next we take the equation y = 4/3x + b and plug in -1 for x and -10 for y to find B.

The area of a rectangle that has a length of 10 and a width of w.
Answer:
B
Step-by-step explanation:
To find the area, multiply length by width (lw, or l×w). If the length is 10, that just leaves the width, which is unknown. We can substitute 10 for l, which leaves us with 10w.
Find the coordinates of the point 3/10 of the way from A to B.
Answer:
[tex] (\frac{3}{13}, -3) [/tex]
Step-by-step explanation:
Apply the formula following formula to find the coordinate pair of the point that is 3/10 of the way from A(-3, -6) to B(11, 7):
[tex] x = \frac{mx_2 + nx_1}{m + n} [/tex]
[tex] y = \frac{my_2 + ny_1}{m + n} [/tex]
Where,
[tex] A(-3, -6) = (x_1, y_1) [/tex]
[tex] B(11, 7) = (x_2, y_2) [/tex]
[tex] m = 3, n = 10 [/tex]
Finding the x coordinate:
[tex] x = \frac{mx_2 + nx_1}{m + n} [/tex]
[tex] x = \frac{3(11) + 10(-3)}{3 + 10} [/tex]
[tex] x = \frac{33 - 30}{13} [/tex]
[tex] x = \frac{3}{13} [/tex]
[tex] y = \frac{my_2 + ny_1}{m + n} [/tex]
[tex] y = \frac{3(7) + 10(-6)}{3 + 10} [/tex]
[tex] y = \frac{21 - 60}{13} [/tex]
[tex] y = \frac{-39}{13} [/tex]
[tex] y = -3 [/tex]
The coordinates of the point 3/10 of the way from A to B are [tex] (\frac{3}{13}, -3) [/tex]

Find the area of a triangle with a base of 27 ft and a height of 14 ft. 41 ft2 82 ft2 189 ft2 378 ft2
Answer:
The answer is 189 ft²Step-by-step explanation:
The area of a triangle can be found by using the formula
[tex]A = \frac{1}{2} \times bh[/tex]
where
b is the base
h is the height
From the question
b = 27 ft
h = 14 ft
Substitute the values into the above formula and solve
That's
[tex]A = \frac{1}{2} \times 27 \times 14 \\ = \frac{1}{2} \times 378 [/tex]
We have the final answer as

Find the area of the given region using any method.
The best method would certainly be integration :)
The area is given by the integral,
[tex]\displaystyle\int_0^2\frac{\mathrm dx}{9-x^2}[/tex]
We can split up the integrand into partial fractions:
[tex]\dfrac1{9-x^2}=\dfrac16\left(\dfrac1{3-x}+\dfrac1{3+x}\right)[/tex]
Then the area is
[tex]\displaystyle\frac16\int_0^2\left(\frac1{3-x}+\frac1{3+x}\right)\,\mathrm dx[/tex]
[tex]=\dfrac16(-\ln|3-x|+\ln|3+x|)\bigg|_0^2[/tex]
[tex]=\dfrac16\left((\ln5-\ln1)-(\ln3-\ln3)\right)=\boxed{\dfrac{\ln5}6}[/tex]

At the beginning of a study of individuals, 10% were classified as heavy smokers, 20% were classified as light smokers, and 70% were classified as nonsmokers. In the five-year study, it was determined that the death rates of the heavy and light smokers were five and three times that of the nonsmokers, respectively. A randomly selected participant died over the five-year period: calculate the probability that the participant was a nonsmoker.
Answer: 0.39
Step-by-step explanation:
Given the following classification :
Heavy smokers (H) = 10%
Light smokers (L) = 20%
Non smokers (N) = 70%
Given that :
The death rates of the heavy and light smokers were five and three times that of the nonsmokers, respectively
Let probability of death = D
P(D | N) = d
P(D | H) = 5d
P(D | L) = 3d
Hence,
P(D) = [P(H) * P(D | H) + P(L) * P(D | L) + P(N) * P(D | N)]
P(D) = [0.1 * 5d + 0.2 * 3d + 0.7 * d]
P(D) = [0.5d + 0.6d + 0.7d]
P(D) = 1.8d
A randomly selected participant died over the five-year period: calculate the probability that the participant was a nonsmoker.
P(N | D) = [P(N) * P(D | N)] / P(D)
P(N | D) = 0.7d / 1.8d
P(N | D) = 0.3888
= 0.39
express sin110 as ratio of acute angle
Answer:
sin70°
Step-by-step explanation:
Given sin110° where 110° is an obtuse angle in the second quadrant.
The related acute angle in the first quadrant is 180° - 110° = 70°
Thus
sin110° = sin70°

Find the equation of the line with slope -2 which goes through the point (-6,-9).
The equation of the line with slope -2 which goes through the point (-6,-9) is y=-2x-21.
What is the equation of a line?The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.
Given that, the line with slope -2 which goes through the point (-6,-9).
Substitute m=-2 and (x, y)=(-6,-9) in y=mx+c, we get
-9=-2×(-6)+c
-9=12+c
c=-21
Substitute m=-2 and c=-21 in y=mx+c, we get
y=-2x-21
Therefore, the equation of the line with slope -2 which goes through the point (-6,-9) is y=-2x-21.

What is formed when polyatomic ions bond with other ions? ionic compounds neutral compounds ionic elements neutral elements
Answer:
iconic compounds
Step-by-step explanation:
Ionic components are formed up of ions, which are charged particles formed whenever an atom (or group of atoms) acquires or loses electrons.
Polyatomic ions were covalently bonded groupings of atoms. It has a positive or negative charge as little more than a result of an ionic bond with the other ion. Polyatomic positive ions are formed from certain ion combinations, however, the polyatomic ion acts as just a single unit.Therefore, the final answer is "ionic compounds".
