Answer:

step below

Step-by-step explanation:

sum of any 2 sides of triangle > third side

AB + BS > AS     (1)

CA + CS > AS     (2)

AB + (BS + CS) + CA > 2 AS      (1)+(2)

AB+BC+CA > 2AS

Answer:

x = 8.7

Step-by-step explanation:

The triangles are congruent, which means that the sides are proportional to each other. Line DE and line BE are proportional to each other. This means that:

8 = 12

We can simplify this down to

2 = 3

Now that we have this proportion we can apply it to Lines AE and EC

2(13) = 3x

26 = 3x

8.67 = x

Therefore x is equal to 8.67 (or 8.7 rounded)

Check:

8/12 = 0.6667

8.6667/13 = 0.6667

Since both are the same, the answer is correct.

I hope this helps!!

Answer:

$360

Step-by-step explanation:

Convert 15% to decimal by dividing 15 by 100 to get 0.15

Multiply 2400 and 0.15 which gets us 360.

Step-by-step explanation:

Answer:

AB is longer than AC which is the letter a

Given:

Consider the given statement is

[tex]\sqrt{\sec^2\theta+\text{cosec}^2\theta}=\tan \theta+\cot \theta[/tex]

To prove:

The given statement.

Solution:

We have,

[tex]\sqrt{\sec^2\theta+\text{cosec}^2\theta}=\tan \theta+\cot \theta[/tex]

Taking LHS, we get

[tex]LHS=\sqrt{\sec^2\theta+\text{cosec}^2\theta}[/tex]

[tex]LHS=\sqrt{\dfrac{1}{\cos^2\theta}+\dfrac{1}{\sin^2\theta}}[/tex]

[tex]LHS=\sqrt{\dfrac{\sin^2\theta+\cos^2\theta}{\sin^2\theta\cos^2\theta}}[/tex]

[tex]LHS=\sqrt{\dfrac{1}{\sin^2\theta\cos^2\theta}}[/tex]            [tex][\because \sin^2\theta+\cos^2\theta=1][/tex]

[tex]LHS=\dfrac{1}{\sin\theta\cos\theta}[/tex]

[tex]LHS=\dfrac{\sin^2\theta+\cos^2\theta}{\sin\theta\cos\theta}[/tex]            [tex][\because \sin^2\theta+\cos^2\theta=1][/tex]

[tex]LHS=\dfrac{\sin^2\theta}{\sin\theta\cos\theta}+\dfrac{\cos^2\theta}{\sin\theta\cos\theta}[/tex]

[tex]LHS=\dfrac{\sin\theta}{\cos\theta}+\dfrac{\cos\theta}{\sin\theta}[/tex]

[tex]LHS=\tan \theta+\cot \theta[/tex]

[tex]LHS=RHS[/tex]

Hence proved.

Answer:

3 down 2 right

Step-by-step explanation:

A is at Y = 1, A’ is at Y = 4

4-1 = 3

It moved up 3 units.

A is at X = 1, A’ is at x = -1

1 - -1 = 2

It moved to the left 2 units.

Answer:

AB=24.5

Step-by-step explanation:

x=3.5

7(3.5)=24.5

Answer:

The ball will be 84 feet above the ground 1.125 seconds and 4.5 seconds after launch.

Step-by-step explanation:

Statement is incorrect. Correct form is presented below:

The height [tex]h(t)[/tex] of an ball that is thrown straight upward from an initial position 3 feet off the ground with initial velocity of 90 feet per second is given by equation [tex]h(t) = 3 +90\cdot t -16\cdot t^{2}[/tex], where [tex]t[/tex] is time in seconds. After how many seconds will the ball be 84 feet above the ground.

We equalize the kinematic formula to 84 feet and solve the resulting second-order polynomial by Quadratic Formula to determine the instants associated with such height:

[tex]3+90\cdot t -16\cdot t^{2} = 84[/tex]

[tex]16\cdot t^{2}-90\cdot t +81 = 0[/tex] (1)

By Quadratic Formula:

[tex]t_{1,2} = \frac{90\pm \sqrt{(-90)^{2}-4\cdot (16)\cdot (81)}}{2\cdot (16)}[/tex]

[tex]t_{1} = 4.5\,s[/tex], [tex]t_{2} = 1.125\,s[/tex]

The ball will be 84 feet above the ground 1.125 seconds and 4.5 seconds after launch.

Answer:

4.66666667

Step-by-step explanation:

Answer:

11 cm

Step-by-step explanation:

the other two choices are too short

If 30 is the hypotenuse, the other two sides must exceed 30.

Answer:

C-11cm

Step-by-step explanation:

The sum of two sides of a triangle must always be bigger than the third!

3+20 is less than 30

6+20 is less than 30

11+20 is greater than 30!

Hope this helps :)

Answer:

soh cah toa

to find a use sin =opp/hyp

sin 32=opp or a /hyp

sin 32*hyp=9.53

then to find b you can pythagorean theorem or just use cah or cos =adj/hyp

same process as above only using cos instead of sin

you get 15.3

then a^2+b^2=c^2

9.53^2+15.3^2=18^2 just to check or to use to find either a or b given c and either a or b

Answer:

  x = 2/3, -1/4

Step-by-step explanation:

The zero product rule tells you a product will be zero only if one or more factors is zero. The solutions to this equation are the values of x that make one or the other of the factors be zero.

  3x -2 = 0

  3x = 2

  x = 2/3 . . . . makes the first factor zero

__

  4x +1 = 0

  4x = -1

  x = -1/4 . . . . makes the second factor zero

__

The solutions are ...

  x = 2/3  or  x = -1/4

Step-by-step explanation:

Answer:

-2 =x

Step-by-step explanation:

2 (x + 3 )= -x⁣

Distribute the 2

2x+6 = -x

Subtract 2x from each side

2x+6-2x = -x-2x

6 = -3x

Divide each side by -3

6/-3 = -3x/-3

-2 =x

Answer:

x = -2

Step-by-step explanation:

2 (x + 3) = -x

2x + 6 = -x

    - 6     -6

2x = -x - 6

+x    + x

3x = -6

---    ----

3      3

x = -2

hope u get it. I've used RHS to prove LHS

the answer is <

Step-by-step explanation:

13 is bigger than 10.

Answer:

Lesser = -490

Greater x = 100x

Step-by-step explanation:

The zeros is basically the opposite numbers to make the equation equal to 0.

We have -10x^2(I believe it's a power)

and we have + 490

so,

-10x^2 = -100x

So the opposites to make those is:

+ 100x because, -100x + 100x = 0

and -490 because, 490 - 490 = 0.
