17. Find an equation for the line passing

Ksivusya [100]

Answer:

Step-by-step explanation:

(3,2),(6,3)

slope = (y2 - y1) /(x2 - x1)

slope = (3 - 2) / (6 - 3) = 1/3

y = mx + b

slope(m) = 1/3

use either of ur points...(3,2)...x = 3 and y= 2

now sub and find b, the y int

2 = 1/3(3) + b

2 = 1 + b

2 - 1 = b

1 = b

so ur equation is : y = 1/3x + 1

Approximate the sum of the convergent infinite series the least usingnumber of terms so that the error is less than .0001. What

____ [38]

Solution :

$\sum_{n=1 }^{\infty } \frac{(-1)^n}{n ! 2^n}$ $a_n= \frac{(-1)^n}{n ! 2^n} \ \ \ \ \ a_{n+1}= \frac{(-1)^{n+1}}{(n+1) ! 2^{n+1}}$

Error = $|a_{n+1}|$

Error ≤ 0.0001

$|\frac{(-1)^{n+1}}{(n+1)!2^{n+1}}| \leq 0.0001$

$|\frac{1}{(n+1)!2^{n+1}}| \leq 10^{-4}$

$(n+1)! 2^{n+1} \geq 10000$

Now try, n ≥ 5

$\sum_{n=1 }^{\infty } \frac{(-1)^n}{n ! 2^n}$ = $\sum_{n=1 }^{5 } \frac{(-1)^n}{n ! 2^n}$ (with error 0.0001)

$\sum_{n=1 }^{\infty } \frac{(-1)^n}{n ! 2^n}$ = $\frac{-1}{1!2}+\frac{1}{2!2^2}-\frac{1}{3! 2^3}+\frac{1}{4! 2^4}-\frac{1}{5! 2^5}$

$\sum_{n=1 }^{\infty } \frac{(-1)^n}{n ! 2^n}$ = 0.6065104

Q(–1, a) is 4 √5 units away from P(3, –2). Find all possible values of a.

vagabundo [1.1K]

Answer:

a=6,-10

Step-by-step explanation:

$4\sqrt{5}=\sqrt{(3+1)^2+(-2-a)^2} \\squaring\\80=16+(2+a)^2\\80-16=(2+a)^2\\(a+2)^2=64\\taking~square ~root\\\\a+2=\pm 8\\either \\a+2=8,\\a=8-2=6\\or\\a+2=-8\\a=-8-2=-10$

Sine of an angle = Opposite side/Hypotenuse

Cosine of an angle = Adjacent side/Hypotenuse

Tangent of an angle = Opposite side/Adjacent side

These three operators can be thought of as ratios of certain sides of a triangle. A ratio is just a comparison of two quantities; or lengths of the sides in this case.
