prove(sec theta-tan theta)(sec theta+tan theta)=1​

Answers

Answer 1

Answer:

[tex]( \sec \theta - \tan \theta)( \sec \theta + \tan \theta)[/tex]

from difference of two squares:

[tex]{ \boxed{ \tt{( {a}^{2} - {b}^{2}) = (a - b)(a + b) }}}[/tex]

[tex] = { \sec }^{2} \theta - { \tan}^{2} \theta \\ = (1 + { \tan}^{2} \theta) - { \tan}^{2} \theta \\ = 1[/tex]

hence proved

(1) Combining fractions is just a matter of writing each individual fraction in terms of a common denominator. The least common multiple of 6, 4, and 8 is

LCM(6, 4, 8) = 24

since 6×4 = 4×6 = 8×3 = 24. So

2/6 = (2×4)/(6×4) = 8/24

1  1/4 = 4/4 + 1/4 = 5/4 = (5×6)/(4×6) = 30/24

13  4/8 = 104/8 + 4/8 = 108/8 = (108×3)/(8×3) = 324/24

Then

2/6 + 1  1/4 + 13  4/8 = 8/24 + 30/24 + 324/24 = 362/24 = 181/12

(2) We have

LCM(12, 9) = 36

since 12×3 = 9×4 = 36. Then

121  2/12 = 1452/12 + 2/12 = 1454/12 = (1454×3)/(12×3) = 4362/36

781  6/9 = 7029/9 + 6/9 = 7035/9 = 2345/3

{ Both are negative integers. So, add and result will have the negative sign}

            = I -9 I

            = 9

Answer:

-36

Step-by-step explanation:

We have the equation 4 lm - nl , along with the values, m is equal to -7 and n is equal to 2.

To solve, we need to only substitute the values of each variable into the original equation :

4 |-7 - 2|

First solve the equation within the absolute value, any value that comes out of those brackets become positive :

|-7 - 2|

|-9|

4|-9|

4(-9)

Now multiply to get our answer:

You have 2 five-dollar bills, 4 one-dollar bills, 2 quarters, I nickel, and 2 pennies. a. What is the value of the bills? b. What is the value of the coins? c. How much money do you have?​

c: [tex]\$14.57[/tex] or [tex]14[/tex] dollars and [tex]57[/tex] cents

Step-by-step explanation:

a: We have [tex]2[/tex] [tex]\$5[/tex] bills, which have a total value of [tex]2*5= \$10[/tex]. We also have [tex]4[/tex] [tex]\$1[/tex] bills, which have a total value of [tex]4*1= \$4[/tex]. Adding these up gives us  [tex]10+4= \bf \$14[/tex] or [tex]\bf 14[/tex] dollars for the total value of the bills.

b: Remember that a quarter is worth [tex]\$0.25[/tex], a nickel is worth [tex]\$0.05[/tex], and a penny is worth [tex]\$0.01[/tex]. Therefore, [tex]2[/tex] quarters are worth [tex]2*0.25=\$0.50[/tex], [tex]1[/tex] nickel is worth [tex]1*0.05=\$0.05[/tex], and [tex]2[/tex] pennies are worth [tex]2*0.01=\$0.02[/tex]. Adding these up gives us [tex]0.50+0.05+0.02=\bf \$0.57[/tex] or [tex]\bf 57[/tex] cents for the total value of the coins.

c: We know that the total value of the bills is [tex]\$ 14[/tex] (or [tex]14[/tex] dollars) from Part A and the total value of the coins is [tex]\$0.57[/tex] (or [tex]57[/tex] cents) from Part B.

The sum of three numbers is 576. One of the numbers, n, is 25 percent more than the sum of the other two numbers. what is the value of n?

Answers

Answer:

Step-by-step explanation:

x + y + n = 576

When something is 25% larger than something else, the effect is the same as multiplying by 1.25. Let's try it with an example

20 + (25/100)* 20 = 20 + 500/100 = 20 + 5 = 25. Now if you multiply 20 * 1.25 you get 25 which is just what you should get.

n = 1.25(x + y)                    Divide by 1.25

n / 1.25 = x + y                   Substitute n / 1.25 for x + y in the above equation    

n/1.25 + n = 576                Multiply everything by 1.25  

n + 1.25n = 576*1.25         Combine the left to get 2.25

2.25 n = 576 * 1.25           Divide by 2.25

n = 576*1.25 / 2.25    

n = 320

Find the equation of the line perpendicular to the 13x-3y=9 and passing through (-5,0)

Answers

9514 1404 393

Answer:

  x +4y = -5

Step-by-step explanation:

The equation of the perpendicular line can be found by swapping the x- and y-coefficients and negating one of them. The new constant can be found by substituting the point values into the equation.

  3x +12y = 3(-5) +12(0)

  3x +12y = -15

We notice that all of the values include a factor of 3. We can divide that out to put the equation in standard form:

  x + 4y = -5
