Answer:

∠2 and ∠3 are complementary

Step-by-step explanation:

Complementary angles add up to 90°. Angles 1 and 3 are complementary, so the formula is ∠1 + ∠3 = 90°. Given that Angle 1 equals to angle 2, we substitute angle 2 for angle one in the equation stated before. Now we have ∠2 + ∠3 = 90°, so angles 2 and 3 are complementary

Answer:

(f-g)(x)  = 2x - x^(-7)

Step-by-step explanation:

We know that

f(x) = 2x^+1 = 2x

g(x)=x^-7 = x^(-7)

Then, we just need to subtract both functions

(f-g)(x) = f(x) - g(x) =  2x - x^(-7)

(f-g)(x)  = 2x - x^(-7)

Please, see attached images for more information

[tex](g\cdot f)(x)=\dfrac{1}{x}-4[/tex]

[tex]D_{g(f(x))}:x\not =0[/tex]

No, since 0 doesn't belong to the domain.

Answer:

The zeros are

[tex]x1=\frac{-5+\sqrt{5}} {2}[/tex]   and [tex]x2=\frac{-5-\sqrt{5}} {2}[/tex]

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form [tex]ax^{2} +bx+c=0[/tex] is equal to

[tex]x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}[/tex]

in this problem we have

[tex]f(x)=x^{2} +5x+5[/tex]  

To find the zeros equate the function to 0

[tex]x^{2} +5x+5=0[/tex]  

so

[tex]a=1\\b=5\\c=5[/tex]

substitute in the formula

[tex]x=\frac{-5(+/-)\sqrt{5^{2}-4(1)(5)}} {2(1)}[/tex]

[tex]x=\frac{-5(+/-)\sqrt{5}} {2}[/tex]

[tex]x1=\frac{-5+\sqrt{5}} {2}[/tex]

Answer:

5*7+3 = 38/7 ~5.43

we can multiple 5 by 7 and add them by 3

For this case we have the following expression:

[tex](-4x) ^ 2 = 100[/tex]

To look for the solution:

 We apply root to both sides of the equation to eliminate the exponent:

[tex]-4x = \pm \sqrt {100}\\-4x = \pm10[/tex]

Then we have two solutions:

[tex]-4x = 10[/tex]

Dividing between -4 on both sides of the equation:

[tex]x = \frac {10} {- 4}\\x = - \frac {5} {2}[/tex]

The second solution:

[tex]-4x = -10[/tex]

Dividing between -4 on both sides of the equation:

[tex]x = \frac {-10} {- 4}\\x = \frac {5} {2}[/tex]

Answer:

[tex]x_ {1} = - \frac {5} {2}\\x_ {2} = \frac {5} {2}[/tex]

Answer:

36

Step-by-step explanation:

Answer:

Just add up the measurements of the sides and then double the result.

(2 + √5 + 6 + 3√5) · 2

= (8 + 4√5) · 2

= 16 + 8√5 (cm)

To answer your question, we first need to understand that the perimeter of a rectangle is calculated by adding up all its sides or simply twice the sum of its length and width.

From the information given, the width of the rectangle is equal to 2 cm plus the square root of 5 cm, while the length is 6 cm plus 3 times the square root of 5 cm.

So now, let's sum up the length and the width:
= (2 + √5 cm) + (6 + 3√5 cm)
= 8 + 4√5 cm

We then multiply this result by 2 (to account for both sets of opposite sides of the rectangle):
Perimeter = 2 * (8 + 4√5 cm)
Perimeter ≈ 33.89 cm

Therefore, the perimeter of the rectangle is roughly 33.89 cm.

Answer:

The equivalent expression is [tex]7^{6}[/tex] ⇒ answer A

Step-by-step explanation:

* Lets revise some rules of the exponents

- In the exponential functions we have some rules

# In multiplication if we have same base then add the power

  b^m  ×  b^n  =  b^(m + n)  

- Ex: [tex]5^{11}*5^{4}=5^{11+4}=5^{15}[/tex]

# In division if we have same base we subtract the power

  b^m  ÷  b^n =  b^(m – n)

- Ex: [tex]\frac{3^{10}}{3^{4}}=3^{10-4}=3^{6}[/tex]

* Now lets solve the problem

- There is the expression [tex]\frac{7^{13}}{7^{7}}[/tex]

- We have base 7 up and down

∵ In division if we have same base we subtract the power

∵ The base up is 7 and the base down is 7

- We will subtract the powers

∴ [tex]\frac{7^{13}}{7^{7}}=7^{13-7}=7^{6}[/tex]

∴ The answer is [tex]7^{6}[/tex]

* The equivalent expression is [tex]7^{6}[/tex]

Answer: Yes.

Step-by-step explanation:

30/5 or 30 divided by 5 simplifies to 6. 6 is a whole number and therefore it is an integer.

The given options are 1) y = (cos x) / x is neither and 2) y = (sin x) / x is even.

Trigonometric ratios for a right-angled triangle are from the perspective of a particular non-right angle.

In a right-angled triangle, two such angles are there which are not right-angled (not of 90 degrees).

The slanted side is called the hypotenuse.

From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called the base.

1) y = (cos x) / x is neither, since cos x is even and x is odd.  

2) y = (sin x) / x is even since sin x and x would either both be positive at the same time or negative at the same time.  

We know that (-) / (-) is positive, just as (+) / (+) is positive.

Final answer:

1. The function y=cos(x)/x is neither even nor odd due to its lack of symmetry properties

2. y=sin(x)/x is an odd function as it satisfies the symmetry condition about the origin.

Explanation:

To determine if the functions y=cos(x)/x and y=sin(x)/x are even, odd, or neither, we need to understand the definitions of even and odd functions and apply them accordingly.

Even and Odd Functions:

An even function satisfies the condition f(-x) = f(x), meaning the function's graph is symmetric about the y-axis. An odd function satisfies the condition f(-x) = -f(x), indicating symmetry about the origin.

Analysis of y=cos(x)/x:

To determine if y=cos(x)/x is even, odd, or neither, replace x with -x:

y=cos(-x)/(-x) = cos(x)/(-x) because cos(-x) = cos(x), an even function property.

This contradicts the definitions of both even and odd functions; hence, y=cos(x)/x is neither even nor odd.

Analysis of y=sin(x)/x:

Similarly, for y=sin(x)/x, replace x with -x:

y=sin(-x)/(-x) = -sin(x)/(-x) because sin(-x) = -sin(x), an odd function property.

This simplifies to y=sin(x)/x, which satisfies the condition for an odd function.

Therefore, y=sin(x)/x is an odd function.

Answer:

-sqrt(3)/2

Step-by-step explanation:

Use double angle identity for sin(2x)

sin(2x)=2sin(x)cos(x)

We are given sin(x)=-1/2 so we already have so far that:

sin(2x)=2(-1/2)cos(x)

sin(2x)=-1*cos(x)

We just need to find cos(x).  

x is in the fourth quadrant so cosine will be positive there

knowing the unit circle we should know that if sin(x)=-1/2 then cos(x)=sqrt(3)/2 while in 4th quadrant.

So the answer is sin(2x)=-1*sqrt(3)/2=-sqrt(3)/2

Hello There!

From Least To Greatest, The Numbers Would Be

20.1, 20.15, 20.479, 20.545, 21.66

Answer:

See below in BOLD.

Step-by-step explanation:

What you need to do is identify the corresponding sides in the polygon than divide the larger length by the smaller.

3.  The side length 8 corresponds to the 4 in the other polygon.

So the scale factor  is 8/4 = 2.

4. Scale Factor = 24/20 = 1.2.

5. 40/32  = 5x / 24

5x = 40*24 / 32

5x = 30

x = 6.

6. 25/30 = 4x + 7 / 42

5/6 = 4x + 7 / 42

6(4x + 7) = 210

24x = 210 - 42 = 168

x = 168/24

x = 7.

7. 40/24 = 3x + 5 / 21

5/3 = (3x + 5) / 21

9x + 15 = 105

9x = 90

x = 10.

8.   24 / 40 = (x + 3) / 15

3/5 = (x + 3) / 15

5x + 15 = 45

5x = 30

x = 6.
