Answer:
For [tex]2log2x=4[/tex] , x = 50
Step-by-step explanation:
Given : [tex]2log2x=4[/tex]
We have to find the value of x.
Consider the given [tex]2log2x=4[/tex]
Divide both side by 2, we have,
[tex]\frac{2\log _{10}\left(2x\right)}{2}=\frac{4}{2}[/tex]
Simplify, we have,
[tex]\log _{10}\left(2x\right)=2[/tex]
[tex]\mathrm{Apply\:log\:rule}:\quad \:a=\log _b\left(b^a\right)[/tex]
[tex]2=\log _{10}\left(10^2\right)=\log _{10}\left(100\right)[/tex]
[tex]\log _{10}\left(2x\right)=\log _{10}\left(100\right)[/tex]
When log have same base, we have,
[tex]\log _b\left(f\left(x\right)\right)=\log _b\left(g\left(x\right)\right)\quad \Rightarrow \quad f\left(x\right)=g\left(x\right)[/tex]
We have,
[tex]2x=100[/tex]
Divide both side by 2, we have,
[tex]x=50[/tex]
Thus, For [tex]2log2x=4[/tex] , x = 50

What is GH ?
Answer: GH =25 in.
Step-by-step explanation:
Given: [tex]ABCD\sim EFGH[/tex]
We know that if two polygons are similar then their corresponding sides are proportional.
Thus, [tex]\frac{AB}{EF}=\frac{BC}{FG}=\frac{CD}{GH}=\frac{AD}{EH}[/tex]
Since, AD=30 in. , EH=50 in. , and CD=15 in.
Then we have ,
[tex]\frac{CD}{GH}=\frac{AD}{EH}\\\\\Rightarrow\frac{15}{GH}=\frac{30}{50}\\\\\Rightarrow\ GH=\frac{50\times15}{30}\\\\\Rightarrow\ GH=25\ in.[/tex]

Enter your answer in the box.
Answer:
[tex]296^{\circ}[/tex]
Step-by-step explanation:
It is given that figure shows circle C with diameter LM and inscribed ∠LMN and m∠LMN=32° .
We know that the angle formed at the center is double the angle formed on the vertex that is an inscribed angle, thus on joining NC, we have

1. What is the sum of the finite arithmetic series? 26 + 29 + 32 + 35 + 38 + 41 + 44
2. What is the sum of the finite arithmetic series? 7.6 + 6.3 + 5 + 3.7 + 2.4 + 1.1 + (–0.2) + (–1.5),
The sum of the finite arithmetic series 26 + 29 + ... + 44 is 245. The sum of the series 7.6 + 6.3 + ... + (-1.5) is 24.4.
To solve these problems, we will use the formula for the sum of a finite arithmetic series, which is given by S = n÷2 × (a₁ + aₙ), where S represents the sum of the series, n is the number of terms, a₁ is the first term, and aₙ is the last term.
Problem 1:
The series is: 26, 29, 32, 35, 38, 41, 44. First, we find the number of terms (n). Since the common difference (d) is 3, we have n = (44 - 26)÷3 + 1 = 7. Now, apply the formula to find the sum: S = 7÷2 × (26 + 44) = 245.
Problem 2:
The series is: 7.6, 6.3, 5, 3.7, 2.4, 1.1, -0.2, -1.5. Here, d = -1.3 and n = 8. So the sum is: S = 8÷2 × (7.6 - 1.5) = 24.4.
Worker A earns $8.10 per widget produced, produces 10 widgets per day, and works 9 hours per day. Worker B earns $8.40 per widget produced, produces 8 widgets per day, and works 7 hours per day. Which of these statements is true?
A. Worker B earns more per day than worker A but less per hour than worker A.
B. Worker A earns more per day than worker B but less per hour than worker B.
C. Worker A earns more per day than worker B and more per hour than worker B.
D. Worker B earns more per day than worker A and more per hour than worker A.
By calculating the total earnings per day and earnings per hour for Worker A and Worker B, we deduce that Worker A earns more per day than Worker B but earns less per hour than Worker B.
Explanation:To answer this question, we first need to calculate the total earnings per day and then the earnings per hour for both Worker A and Worker B.
For Worker A, the total earnings per day can be calculated as: 10 widgets/day * $8.10/widget = $81/day. For Worker B, the total earnings per day can be calculated as: 8 widgets/day * $8.40/widget = $67.20/day.
Therefore, we can see that Worker A earns more per day than Worker B.
Next, we calculate the earnings per hour. For Worker A, the earnings per hour amount to: $81/day ÷ 9 hours/day = $9/hour. For Worker B, the earnings per hour amount to: $67.20/day ÷ 7 hours/day = $9.60/hour.
Thus, Worker B earns more per hour than Worker A.
Given the calculations, the correct statement is B. Worker A earns more per day than Worker B but less per hour than Worker B.

1. Simplify the product.
7x (x+4)
A) 7x^2 + 4
B) 7x^2 + 28x
C) 8x + 4
D) 8x + 11,
The simplified product is 7x² + 28x.
Option B is the correct answer.
We have,
To simplify the product 7 x (x + 4), we need to distribute the 7x to both terms inside the parentheses.
The distributive property states that for any numbers a, b, and c,
a x (b + c) = a x b + a x c.
Applying this property to the given expression, we have:
(7x) x (x) + (7x) x 4
Multiplying 7x by x gives us 7x², and multiplying 7x by 4 gives us 28x.
So the simplified expression becomes:
7x² + 28x

The simplified product is 7x² + 28x.

What is the definition of asymptote?
What is the facts or characteristics of asymptote?
What is some examples of asymptote?
What is some non-examples of asymptote?
An asymptote is a line that approaches a curve indefinitely without intersecting it at any finite point. Examples include the line y = 0 for the function y = 1/x, whereas a non-example would be the intersecting line y = x with a parabola y = x^2.
Explanation:An asymptote is a line that a curve approaches as it heads towards infinity, but never actually reaches.
There are several characteristics of an asymptote that are notable. First, the distance between the curve and the asymptote approaches zero as one moves along the curve towards infinity. However, the curve will never intersect the asymptote at any finite point. There are two main types of asymptotes: vertical and horizontal.
An example of an asymptote is the line y = 0, which is a horizontal asymptote for the function y = 1/x as x approaches infinity.
A common non-example of an asymptote is any line or curve that intersects a graph at a finite number of points, such as the line y = x when compared with a parabola y = x2.

two vertical cliffs are on opposite sides of a 90 foot wide river. From point A at the top of the shorter cliff, the angle of elevation of the top of the other cliff(b) is 28 degress and the angle of depression to the bottom is 38 degress.find the height of each cliff ,to the nearest foot
Final Answer:
The height of the shorter cliff is 70 feet and the height of the taller cliff is 118 feet.
Explanation:
To find the height of each cliff, we will use trigonometry. Specifically, we will use the tangent function, which is the ratio of the opposite side to the adjacent side of a right-angled triangle.
First, let's consider the shorter cliff (point A). We know the angle of depression from A to the bottom of the river is 38 degrees. If we imagine a horizontal line at the height of point A, we can create a right-angled triangle with one angle at the bottom of the river, the vertical side as the height of the cliff, the horizontal side as the width of the river, and the angle of depression at point A.
Using the tangent of the angle of depression, we can set up the following equation to find the height of the shorter cliff (which we will call hA):
tan(38 degrees) = height_shorter_cliff / width_river
Solving for the height of the shorter cliff, we get:
height_shorter_cliff = width_river * tan(38 degrees)
Using a calculator or trigonometry tables, we find that the height of the shorter cliff is approximately 70 feet.
Next, let's consider the taller cliff (point B). The angle of elevation from A to B is given as 28 degrees. Now we can imagine another right-angled triangle, this time with one angle at point A, the vertical side as the difference in height between cliffs A and B, the horizontal side as the width of the river, and the angle of elevation at point A.
Using the tangent of the angle of elevation, we can set up an equation to find the height difference between cliffs A and B (which we will call hB - hA):
tan(28 degrees) = (height_taller_cliff - height_shorter_cliff) / width_river
We can rearrange this to solve for the height of the taller cliff:
height_taller_cliff = width_river * tan(28 degrees) + height_shorter_cliff
Now, using our previous result for the height of the shorter cliff (70 feet), we plug it into our equation:
height_taller_cliff = 90 * tan(28 degrees) + 70
Using a calculator or trigonometry tables to evaluate tan(28 degrees), we find that the height of the taller cliff is approximately 118 feet.
Therefore, to the nearest foot, the height of the shorter cliff is 70 feet and the height of the taller cliff is 118 feet.
