Answer:

  (a, b) = (√2/2, √2/2) . . . . . choice C in each case

Step-by-step explanation:

The points on a unit circle will not have coordinate values greater than 1 (eliminates √2). The coordinates will only be 0 or 1 if the point is on one of the axes. The coordinates (a, b) of the point at 45° are ...

  (cos(45°), sin(45°)) = (a, b) = (√2/2, √2/2)

The coordinate of point (a, b) is (√2/2, √2/2)

Note that the points on a unit circle will not have coordinate values greater than 1.

The coordinates will only be 0 or 1 if the point is on one of the axes. The coordinates (a, b) of the point at 45° is given according to the coordinate point (cos45, sin45)

a = cos45 = √2/2

b = sin45 = √2/2

Hence the coordinate of point (a, b) is (√2/2, √2/2)

Answer:

x = 4

Step-by-step explanation:

x + x + 6 + 6 = x + 8 + 8

2x + 12 = x + 16

2x + 12 - 12 = x + 16 - 12

2x + 0 = x + 4

2x = x + 4

2x - x = x + 4 - x

2x - x = x - x + 4

x = 0x + 4

x = 0 + 4

x = 4

Chequando Respuesta :

x = 4

x + x + 6 + 6 = x + 8 + 8

(4) + (4) + 6 + 6 = (4) + 8 + 8

4 + 4 + 6 + 6 = 4 + 8 + 8

8 + 6 + 6 = 12 + 8

14 + 6 = 20

20 = 20

Ambos lados de la ecuacio'n son igual cuando x = 4, y esto confirma que la respuesta es corecta, que x = 4 en este problema.

Answer: 21

Step-by-step explanation:

First, divide 14 by 2 which is 7. Then multiply 7 by 3 because it's 2/3 so that is 21. The answer is 21

The exponential decay function is given by  y=2000×0.9ˣ and the stock will be worth $1180.98 after a period of 5 years.

In mathematics, exponential decay describes the process of reducing an amount by a consistent percentage rate over a period of time. It can be expressed by the formula y=a(1-b)ˣ wherein y is the final amount, a is the original amount, b is the decay factor, and x is the amount of time that has passed.

Given here: The value of the stock in 2012 was $2000 and the value decreases each year by 10%

We know the exponential decay is given by  y=a(1-b)ˣ

where x is the number of years and 1-b is the decreasing factor

Thus based on the given information we can construct the exponential decay function as y=2000(1-10%)ˣ

or y=2000×0.9ˣ

Therefor in 5 years i.e in 2017 the stock will be worth

y=2000×0.9⁵

=$1180.98

Hence, The exponential decay function is given by  y=2000×0.9ˣ and the stock will be worth $1180.98 after a period of 5 years.

Answer:

what ur yourgrade?

Step-by-step explanation:

Answer:

5) x=19 ft.

6) x=3 cm.

7) x=50 ft.

8) 56 mm.

Explanation:

All of these problems require proportions. For example, in #5, the smaller rectangle has a width of 8 ft. and a length of 24 in. and the larger rectangle has a length of 57 in. but the width is not given. Now, we know that [tex]\frac{8}{24}[/tex][tex]=\frac{x}{57}[/tex]. Cross-multiply to get 456=24x. Divide 24 on both sides to get x=19 ft.

Answer:

It can be shown that opposite sides of parallelogram must be congruent , that opposite angles are also congruent , and that consecutive angles are supplementary . ...

The perimeter of a parallelogram is the sum of the lengths of its four sides. ...

Therefore, the perimeter is 6+10+6+10 or 32 cm.

Step-by-step explanation:

Answer:

Perimeter is always the same, add the outer lengths of all the sides. A+B+A+B=T

Or

2(A+B)

Area is just B * H when you have the height available.

You can also use a trig function A = ab sin (x)

Answer:

E[T] = 10

Step-by-step explanation:

A distribution is called uniform if each outcome has the same probability of happening.

The uniform distribution has two bounds, a and b, and the expected value of the uniform distribution is given by:

[tex]E = \frac{a+b}{2}[/tex]

Uniformly distributed between 0 and 20 minutes.

This means that [tex]a = 0, b = 20[/tex]

Let T be the number of minutes you wait until you board a bus. Find E[T].

This is

[tex]E[T] = \frac{a + b}{2} = \frac{0 + 20}{2} = 10[/tex]

E[T] = 10
