The difference of the squares of two positive consecutive even integers is 4444. find the integers. use the fact​ that, if x rep
Sergio [31]

Remember that the formula for the difference of squares is a^2 - b^2, where a and b are expressions or values.


In this case, we have two expressions, x and (x + 2). We are also given that their difference of squares is 4444. Using the formula, we can say:

(x + 2)^2 - x^2 = 4444


Now, we can solve for x:

(x + 2)^2 - x^2 = 4444

(x^2 + 4x + 4) - x^2 = 4444

4x + 4 = 4444

4x = 4440

x = 1110


We now know that the first number is 1110. To find the second number, we must add 2 to the first number, which means that the second number, represented by (x + 2), is equal to 1112.


Our two numbers are 1110 and 1112.

galben [10]
The formula for this is d=rt  where d= distance, r= rate of travel, and t= time
d= 3(.083)  (5 minutes divided into 60 minutes per hour)
You could also convert the miles per hour to miles per minute and use the 5.  3/60= .05 miles per minute.
d= .05(5)
d= .25 miles
d= .249 miles

suppose for an angle theta in a right triangle cos theta = C. Sketch and label this triangle, and then use it to write the other
VARVARA [1.3K]

Answer:

sin\theta = \sqrt{1-C^2}

tan\theta = \dfrac{\sqrt{1-C^2}}{C}

cot\theta = \dfrac{C}{\sqrt{1-C^2}}

sec\theta = \dfrac{1}{C}}

cosec\theta = \dfrac{1}{\sqrt{1-C^2}}

Step-by-step explanation:

Given that:

\theta is an angle in a right angled triangle.

and cos\theta = C

To find:

To draw the triangle and write other five trigonometric functions in terms of C.

Solution:

We know that cosine of an angle is given by the formula:

cosx =\dfrac{Base}{Hypotenuse}

Here, we are given that cos\theta = C OR

cos\theta = \dfrac{C}{1}

i.e. Base = C and Hypotenuse of triangle = 1

Please refer to the right angled triangle as per given statements.

\triangle PQR, with base PR = C units

and hypotenuse, QP = 1 unit

\angle R is the right angle.

Let us use pythagorean theorem to find the value of perpendicular.

According to pythagorean theorem:

\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}

1^{2} = C^{2} + QR^{2}\\\Rightarrow QR = \sqrt {1-C^2}

sin\theta = \dfrac{Perpendicular}{Hypotenuse}\\\Rightarrow sin\theta = \dfrac{\sqrt{1-C^2}}{1}\\\Rightarrow sin\theta = \sqrt{1-C^2}

tan\theta = \dfrac{Perpendicular}{Base}\\\Rightarrow tan\theta = \dfrac{\sqrt{1-C^2}}{C}

cot\theta = \dfrac{Base}{Perpendicular}\\\Rightarrow cot\theta = \dfrac{C}{\sqrt{1-C^2}}

sec\theta = \dfrac{Hypotenuse}{Base}\\\Rightarrow sec\theta = \dfrac{1}{C}}

cosec\theta = \dfrac{Hypotenuse}{Perpendicular}\\\Rightarrow cosec\theta = \dfrac{1}{\sqrt{1-C^2}}
