Write the equation in logarithmic form.

25 = 32



A. log32 = 5 • 2


B. log232 = 5


C. log32 = 5


D. log532 = 2

Answers

The equation in logarithmic form is B.log₂32 = 2.

To convert the equation 2⁵ = 32 into logarithmic form, you need to identify the base, the exponent, and the result. The given equation can be interpreted as 2 raised to the power of 5 equals 32.

The general form of a logarithmic equation is: log_base (result) = exponent

In this specific case, we have:

base = 2
result = 32
exponent = 5

Putting it into the logarithmic form, we get: log₂32 = 5

So, the correct option is: B.log₂32 = 2

Triangle END is translated using the rule (x, y) → (x − 4, y − 1) to create triangle E'N'D'. If a line segment is drawn from point E to point E' and from point N to point N', which statement would best describe the line segments drawn? (1 point

Answers

Here are the choices for this problem:
They are parallel and congruent.
They are perpendicular to each other.
They share the same midpoints.
They create diameters of concentric circles.

The transformation that is done is a translation. Which means that the coordinates will be translated or moved in the coordinate plane without changing the size and the orientation of the image. If is a line was drawn from E to E' and another line was drawn from N to N', the two lines would be parallel and congruent since the translation done to E is the same to that of N.

The answer is
They are parallel and congruent. 

This answer is right!!!!! They are parallel and congruent.

A triangle has one leg measuring 10 inches and the hypotenuse measuring 20 inches. the other leg measures 10\sqrt[]{3} 10 3 inches. what type of triangle is represented here?

Answers

From the description given for the triangle above, I think the type of triangle that is represented would be a right triangle. This type of triangle contains a right angle and two acute angles. In order to say or prove that it is a right triangle, it should be able to satisfy the Pythagorean Theorem which relates the sides of the triangle. It is expressed as follows:

c^2 = a^2 + b^2

 where c is the hypotenuse or the longest side and a, b are the two shorter sides.

To prove that the triangle is indeed a right triangle, we use the equation above.

c^2 = a^2 + b^2
c^2 = 20^2 = 10^2 + (10sqrt(3))^2
400 = 100 + (100(3))
400 = 400

What is the sum of the arithmetic sequence 3, 9, 15..., if there are 26 terms?

Answers

9 - 3 = 6, 15-9 = 6 the difference is 6, So d = 6

First term: a1 = 3


Sn = n*(a1 + an)/2

Sn = n*(a1 + a1 + (n-1)*d)/2

Sn = n*(2*a1 + (n-1)*d)/2

 substitute 26 for n
S26 = 26*(2*a1 + (26-1)*d)/2

substitute 3 for a1

S26 = 26*(2*3 + (26-1)*d)/2

substitute 6 for d

S26 = 26*(2*3 + (26-1)*6)/2  

S26 = 2,028


Sum of an arithmetic series is:

S = n*(a_1+a_n)/2, that easy.

n is the number of terms, 26 in your case. a_n is a_26. We need to find the series!

a_n = a_1 + (n-1)*d, the difference, d, is 6.

So a_n = 3 + (n-1)*6 = 6*n-3 (check it works: 3, 9, 15, ...)

Now a_26 = 6*26-3 = 153, so finally:

S = 26*(3+153)/2 = 26*78 = 2028

2028 is the answer

The area of a rectangle is 33 m2 , and the length of the rectangle is 5 m less than double the width. find the dimensions of the rectangle.

Answers

By definition, a rectangle is a quadrilateral (4-sided polygon) containing two sets of equal and parallel sides called the length and the width. For determining the area of a rectangle, you simply have to multiply length times width. In this problem, let L be the length and W be the width. Then, we formulate the two independent formulas: formula for area, and formula relating L and W

A = LW = 33
L = 2W-5

Substituting the second equation to the first,

A = 33 = (2W - 5)W
33 = 2W² - 5W
2W² - 5W -33 = 0
W = 5.5 and -3

Since the equation is quadratic, there are two possible roots: 5.5 and -3. However, we can only use the positive value. Thus, W=5.5 m. Consequently,

L = 2(5.5)-5
L = 6 m

Therefore, the dimensions of the rectangle is 6 m by 5.5 m.

The graph of the function f(x) = (x² + 3x + 5 )/(x+ 2) is a parabola that is shifted to the left by 2 units.

The parabola is similar to the graph of the function y = x², but it is narrower because the denominator of the fraction is x + 2.

The graph also has a hole at the point (-2, 5), which is the point where the denominator of the fraction is 0.

How many three-letter "words" can be made from 5 letters "fghij" if repetition of letters (a) is allowed?

Answers

From the given, there are 5 letters to choose from. For the first letter of the three-letter word, we can choose from all 5 of them. 

Also, for the second letter of the word, we can also have 5 choices because it is stated that repetition is allowed. Similarly, there are also 5 choices for the last letter of the word. By fundamental principle of counting, we multiply the numbers identified in the sentences above,
   
                                n = 5 x 5 x 5 = 125

Thus, 125 words can be formed from the given letters.

The length of the arc is a fraction of the circumference of the circle depending on the length of the radius and the intercepted angle. This can be calculated through the equation,

                    L = (2πr) x (θ /360)

where L is the length of arc, r is the radius, and θ is the intercepted angle in terms of degrees. 

Substituting the known values to the equation,

                   36 = (2π)(15)  x (θ / 360)

We translate the equation to find the value of θ,

                               θ = (36)(360) / 2π(15)

The value of θ is equal to 137.51°

This can be coverted to radians through the equation below,

                              θ (in radians) = 137.51° x (2π rad / 360°) = 2.4 rad

Determine the slope of a line that makes an angle of 5pi/4 radians with the x-axis.

check the picture.

π radians is the angle 180 degrees, so π/4 radians is 180°/4=45°.

to construct the angle [tex]5 \frac{ \pi}{4} [/tex] we can proceed as shown in the figure, that is, we open an angle equal to 5 half right angles.

We see that the line making the angle 5pi/4 is the same line making the angle pi/4 radians, that is 45 degrees.

A line making the angle 45 degrees with the x axis, has slope equal to 1. 

Remark, we have considered a line passing through the origin, as it represents all other lines making 5pi/4 radians.

Line EF has an equation of a line y = −2x + 7. Which of the following could be an equation for a line that is perpendicular to line EF?

y = 2x − 3
y = 1 over 2x − 3
y = −2x − 3
y = −1 over 2x − 3

Answers

1.

When a line is given in the form y=mx+n, 

m is the slope of this line.

For example, the slope of the line y=-2x+7 is -2.

2. 

If lines y=mx+n and y=kx+t are perpendicular, then the multiplication of their slopes is -1, that is

m*k = -1, so k=-1/m

3.

any line perpendicular to y=-2x+7 has slope = -1/(-2)=1/2

4.

Among the choices, y=(1/2)x-3 is a line perpendicular to the given line.

Answer: 

b. y=(1/2)x-3 

Answer:

[tex]y=\frac{1}{2} x-3[/tex]

Step-by-step explanation:

Step 1

Find the slope of the line EF

we have

[tex]y=-2x+7[/tex]

The slope of the line EF is equal to

[tex]m=-2[/tex]

Step 2

Find the slope of the line perpendicular to the line EF

we know that

If two lines are perpendicular, then the product of its slopes is equal to minus one

so

[tex]m1*m2=-1[/tex]

we have

[tex]m1=-2[/tex] -----> slope of the line EF

Find the value of m2

substitute

[tex](-2)*m2=-1[/tex]

[tex]m2=1/2[/tex]

therefore

the equation [tex]y=\frac{1}{2} x-3[/tex] could be an equation for a line that is perpendicular to line EF

let y=(sinx)^2
