Use the Pythagorean Identity to find cosθ if sinθ=(√2)/2 and θ terminates in Quadrant I.

Answers

Answer 1

Value of cosθ will be cosθ = (√2)/2 after using Pythagorean Identity.

The Pythagorean Identity states that sin²θ + cos²θ = 1. We can use this identity to find cosθ given that sinθ = (√2)/2 and θ terminates in Quadrant I.

Since sinθ = (√2)/2 and θ terminates in Quadrant I, we can draw a right triangle with angle θ in Quadrant I, opposite side equal to √2, adjacent side equal to 1, and hypotenuse equal to √3.

Using the Pythagorean Theorem, we can find the length of the hypotenuse as:

h² = a² + b²

√3² = 1² + (√2)²

3 = 1 + 2

3 = 3

So, the length of the hypotenuse is √3.

Now, we can use the Pythagorean Identity to find cosθ:

sin²θ + cos²θ = 1

Substituting sinθ = (√2)/2:

(√2/2)² + cos²θ = 1

Simplifying:

2/4 + cos²θ = 1

1/2 + cos²θ = 1

cos²θ = 1 - 1/2

cos²θ = 1/2

Since θ terminates in Quadrant I and sinθ is positive, we know that cosθ is also positive. Therefore, taking the positive square root of both sides, we get:

cosθ = √(1/2) = (√2)/2

So, cosθ = (√2)/2.

Find the difference quotient f(x+h) -f(x)/h , where h does not equal 0, for the function below.
f(x)=-3x^2+6x-6

Answers

The difference quotient for the function f(x)=-3x²+6x-6 is -3h+6.

Now, let's move on to finding the difference quotient for the function f(x)=-3x²+6x-6. The difference quotient is a formula used to find the average rate of change of a function between two points.

The formula for the difference quotient is:

f(x+h) - f(x)

So, to find the difference quotient for the function f(x)=-3x²+6x-6, we first need to find f(x+h) and f(x):

f(x+h) = -3(x+h)² + 6(x+h) - 6

= -3(x² + 2xh + h²) + 6x + 6h - 6

= -3x² - 6xh - 3h² + 6x + 6h - 6

f(x) = -3x² + 6x - 6

Now we can plug these values into the difference quotient formula:

f(x+h) - f(x)

= [-3x² - 6xh - 3h² + 6x + 6h - 6] - [-3x² + 6x - 6]

= [-3x² - 6xh - 3h² + 6x + 6h - 6 + 3x² - 6x + 6] / h

= [-3h² + 6h] / h

= -3h + 6

This tells us the average rate of change of the function between x and x+h is -3h+6.

Answers

The correct statement is,

D) The median is less than the mean.

E) The mode and the mean are equal.

Given that;

Data set is,

⇒ {60, 5, 18, 20, 37, 37, 11, 90, 72}

Hence, We can formulate;

Mean = {60 + 5 + 18 + 20 + 37 + 37 + 11 + 90 + 72} / 9

Mean = 38.89

Arrange data set into ascending order,

⇒ 5, 11, 18, 20, 37, 37, 60, 72, 90

Hence,

Median = (9 + 1)/2

            = 5th term

Answer:

the equilibrium output (Y) is (gA-b(10))Mo + 2520/25 = 1076 and the equilibrium interest rate (i) is -176.

Step-by-step explanation:

(a) Writing the IS-LM system in matrix form:

IS equation: Y = 1 - b(10) + gA

LM equation: Y = (Mo/k) - (/k)i

We can rewrite the equations in matrix form as:

| 1 - b(10) -gA | | Y | | 0 |

| 1/k /k | | i | = | Mo/k |

(b) Solving for Y and i by matrix inversion:

| Y | | (1/k) (gA-b(10))/k | | 0 |

| i | = | (1/k) (-1/k) | | Mo/k |

Multiplying the inverse matrix by the right-hand side:

| Y | | (1/k) (gA-b(10))/k | | 0 | | (gA-b(10))Mo/k |

| i | = | (1/k) (-1/k) | | Mo/k | = | -Mo/k |

Solving for Y and i:

Y = (gA-b(10))Mo + 2520

25

i = -176

Therefore, the equilibrium output (Y) is (gA-b(10))Mo + 2520/25 = 1076 and the equilibrium interest rate (i) is -176.

Answer:

[tex]j = 7 \pm \sqrt{44}[/tex]

Step-by-step explanation:

First, move the constant term to the other side of the equation.

[tex]j\² + 14j + 5 = 0[/tex]

[tex]j\² + 14j = -5[/tex]

Next, add the coefficient of the first degree j term divided by 2, then squared to both sides.

[tex]j^2 + 14j + (14/2)^2 = -5 + (14/2)^2[/tex]

[tex]j^2 + 14j + (7)^2 = -5 + (7)^2[/tex]

[tex]j^2 + 14j + 49 = -5 + 49[/tex]

[tex]j^2 + 14j + 49 = 44[/tex]

Now, we can factor the left side as a square.

[tex](j+7)(j+7) = 44[/tex]

[tex](j+7)^2 = 44[/tex]

Finally, we can take the square root of both sides to solve for j.

[tex]\sqrt{(j+7)^2} = \sqrt{44[/tex]

[tex]j+7=\pm\sqrt{44}[/tex]

[tex]\boxed{j = 7 \pm \sqrt{44}}[/tex]

Note that there are two solutions, as [tex]\sqrt{44[/tex] could be positive OR negative because of the even root property:

then [tex]x = \pm a[/tex]

What is the probability of randomly selecting a blue jelly bean from the first bag and then randomly selecting a green jelly bean from the second bag?


1/15


3/10


7/25


1/4

Answers

The probability of randomly selecting a blue jelly bean from the first bag and then randomly selecting a green jelly bean from the second bag is 1/15 (option a).

Firstly, we need to determine the total number of jelly beans in both bags.

The first bag contains 15 jelly beans (3+5+2+5) and the second bag contains 10 jelly beans (1+7+2).

Therefore, the total number of jelly beans in both bags is 25.

Next, we need to determine the probability of randomly selecting a blue jelly bean from the first bag.

Since there are 5 blue jelly beans out of a total of 15 jelly beans in the first bag, the probability of selecting a blue jelly bean is 5/15 or 1/3.

After selecting a blue jelly bean from the first bag, we move on to the second bag to select a green jelly bean.

Since there are 2 green jelly beans out of a total of 10 jelly beans in the second bag, the probability of selecting a green jelly bean is 2/10 or 1/5.

To determine the probability of both events occurring, we use the multiplication rule of probability.

Therefore, the probability of randomly selecting a blue jelly bean from the first bag and then randomly selecting a green jelly bean from the second bag is (1/3) x (1/5) = 1/15.

Hence, the answer is option (a) 1/15.
