Answer:

Step-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

Step-by-step explanation:

use the order of operations

5 (3) 2 + 3 + 11. solve within parenthesis

15 × 2 + 3 + 11. multiply left to right

30 + 3 + 11. multiply left to right

33 + 11. add left to right

44. add

the order of operations is more commonly known as PEMDAS.

The equation of the line with slope -2 which goes through the point (-6,-9) is y=-2x-21.

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.

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.

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]

Answer:

60

Step-by-step explanation:

Since Jim sold 1/3 of his stamps on Monday, the remainder would be 2/3 of his total stamps.

Divide 360 stamps by 3. Minus the stamps sold on Monday from 360 to get the remainder.

stamps sold on Monday = 360 ÷ 3 = 120

remainder = 360 - 120 = 240

He sold 1/4 of the remainder on Tuesday.

Divide the remainder by 4.

stamps sold on Tuesday = 240 ÷ 4 = 60

He sold 60 stamps on Tuesday.

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]

Step-by-step explanation:

So we have the two functions:

[tex]f(a)=2a-1\text{ and } g(a)=4a-1[/tex]

And we want to find f(a) + g(a).

So, substitute:

[tex]f(a)+g(a)[/tex]

This is the same as:

[tex]=(2a-1)+(4a-1)[/tex]

Combine like terms:

[tex]=(2a+4a)+(-1-1)[/tex]

Add or subtract:

[tex]=6a-2[/tex]

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

Answer:

y = -2x + 9

Step-by-step explanation:

Let's start from the -2x, the slope is -2. The x is basically what says, this is the slope. The plus nine is the y-intercept. If you think in graph terms (which is how you solve this problem) you will see that on the y-axis the line will intercept at the 9. The every x integer it goes down it goes that times two. For example, if you go sideways 1 spot, the line will be at y=11.
