Answer:

so -2024y0000 division is s

The ratio that can be used to find x is sin 21 = x/22.

The trigonometric ratios are the ratios that we can use to obtain the sides and the angles that are in a right angled triangle. The term right angled triangle has to do with a triangle that has one of its angles as 90 degrees.

Now;

Given that;

Sin θ = opposite/hypotenuse

opposite = x

hypotenuse = 22

θ  = 21 degrees

It now follows that to obtain the side x we have to use;

sin 21 = x/22

75 kilometers west = 75 W

Kirk will drive East to get home = ?

since the distances are all in the horizontal direction we add up the west directions and subtract the east direction

Answer:

No real zeros.

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{7.4 cm}\underline{Discriminant of the Quadratic Formula}\\\\$b^2-4ac$ \quad when $ax^2+bx+c=0$\\\\When $b^2-4ac > 0 \implies$ two real zeros.\\When $b^2-4ac=0 \implies$ one real zero.\\When $b^2-4ac < 0 \implies$ no real zeros.\\\end{minipage}}[/tex]

The value of the discriminant shows how many zeros the function has.

Given quadratic function:

Therefore:

Substitute the values into the discriminant and solve:

The standard error of the mean is 11.99

Given,

In the question :

No. of observation is  100

The sample mean is = 1234

Standard Deviation is = 120

To find the standard error of the mean.

Noe, According to the question:

No. of observation:

Where,

∈ = allowance % error of mean

[tex]C_{v}[/tex] = coefficient of variation

[tex]C_{v} =[/tex] σ / x bar × 100

σ = standard deviation and x bar = mean

x bar = 1234 , σ = 120 and N = 100

[tex]C_{v} = \frac{120}{1234}[/tex]  × 100

[tex]C_{v}[/tex] = 9.72%

N = [tex](C_{v}[/tex] / ∈[tex])[/tex] ^2

100 = (9.72/∈)^2

The equation of line passing through the point (-3, -1) and is perpendicular to the line y = -x/2 - 5 is y = 2x + 5

perpendicular lines are defined as two lines that meet or intersect each other at right angles (90°).

In such lines the product of their gradients is -1.

if y = -x/2 - 5

then comparing the equation with y = mx + c

it means slope(m) = -1/2

so the slope(p) of the second line perpendicular to the above line will be

p x m = -1

p = -1/m

p = -1 ÷ -1/2

p = 2

so if x = -3, y = -1 and substituting these values into the equation of line , y = mx + c becomes

-1 = 2 x (-3) + c

-1 = -6 + c

collect like terms

c= 6 - 1

The equation of the required perpendicular line is y = (-5/4)x - 30.

We are given an equation. The equation is linear in nature. The equation represents a straight line. The equation of the given straight line is y = (4/5)x + 23. We need to find the equation of the straight line that is perpendicular to the given line and passes through the point that has coordinates (-40, 20).

The slope of the given line is 45. Let the slope of the required perpendicular line be represented by the variable "m". The slope of the perpendicular line must be the negative reciprocal of the slope of the given line.

m = -1/(4/5)

m = -5/4

The equation of the required line is of the form y = mx + c.

y = (-5/4)x + c

We know that this line passes the point (-40, 20).

20 = (-5/4)(-40) + c

20 = 50 + c

c = -30

Hence, the equation of the required line is y = (-5/4)x - 30.

m∠1 = 43° because opposite angles are congruent

m∠2 = 137° because ∠2 and 43° are supplementary, so m∠2 + 43° = 180°

m∠3 = 137° because opposite angles are congruent, so m∠3 = m∠2

m∠5 = 43° because alternate angles are congruent

m∠6 = 137° because ∠5 and ∠6 are supplementary, so 43° + m∠6 = 180°

m∠7 = 137° because alternate exterior angles are congruent, so m∠7 = m∠2

m∠8 = 43° because alternate exterior angles are congruent, so m∠8 = m∠1

Answer:

angle 1: 43

angle 2: 137

Step-by-step explanation:

Lets find angle 1 first :)

Since oposite diagonal angles are the same, this will make angle 1 43 degrees :)

Now lets find angle 2!

Since 1 was 43 degrees, and a flat line is 180 degrees we must subtract!

Lets do that now!

180 - 43 = 137

Angle 2 will be 137 degrees!

The average speed of the train is 18m/sec and the length of the train is 72 m.

let  x represent the length of the train.

and 'S' be the speed of the train.

Given, that the train passes through 360 m long tunnel  completely in 24 sec.

⇒ 360+x/24 = s

⇒ 24s = 360+x ...eq(1)

And also given that it passes through another tunnel 216 m long completely in 16 sec.

⇒ 216+x/24 = s

⇒ 16s = 216 + x .... eq(2)

⇒ subtract eq(1) from eq(2)

⇒ 24s = 360 + x

   16s = 216 + x

8s = 144

s = 18 m/sec

length of the train: 24s = 360+x

24(18) = 360+x

432 = 360+x

x = 432-360

x = 72m

The equation of the parabola, in vertex form, that represents the ball's distance, y, from the hole, x seconds after the ball is hit is

y = (-2m/s^2)t^2 + (-2m/s)t + 6m

ax² + bx + c = 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. a 0. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.

Given,

Assume for the moment that the hole is located at y = 0m, where x represents the time variable.

We are aware of:

The vertices are (-1s, 8m).

x in seconds and y in meters, I presume

The ball enters the hole at time x = 1s, hence we also have the following point:

(1s, 0m).

The vertex of the quadratic equation y = ax2 + bx + c is located at:

x = -b/2a,

Next, we have:

-1 = -b/2a.

Next, we have equations for trees:

8m = a(-1s)2, b(-1s), and c

0m = (a(1s)2) + (b(1s)2) + (c)

-1s = -b/2a.

The third equation should have one variable isolated first, and then it should be substituted in one of the other two:

1s2a = b.

Therefore, we can change b to bi 1s2a in the first two equations.

8m = 1s×2a×1s - a×1s2a1s + c

0m = 1s×2a×1s + a×1s×2a + c

We can combine the two equations to get:

8m is equal to a(1s2 - 2s2) + c, or a×1s2 - c.

0m is equal to a(1s2 + 2s2) + c, or a×3s2 + c.

We may quickly remove c from the second equation and then substitute it in the first equation:

c = -a3s^2

The initial equation is now:

8m is equal to -a×1s2 - a×3s2 - a×4s2.

a = 8m/-4s^2 = -2m/s^2.

We can now determine the values of c and b using a.

c = -(-(-2m/s2)*3s2)*3s2 = 6m.

B is equal to 1s*2a = 1s*(-2m/s2) = -2m/s.

The equation is then:

y = (-2m/s^2)t^2 + (-2m/s)t + 6m
