What is an
equation of the line that passes through the points (0, -1) and (6, 1)?
Answer:
y = 1/3x -1
Step-by-step explanation:
The slope is y2 - y1 / x2 - x1
y2 is 1
y1 is -1
x2 is 6
x1 is 0
So it is 1 - (-1) / 6 - 0, or 2/6, or 1/3
The slope is 1/3.
The y-intercept is the place where x is 0. It shows the y-intercept here as
(0, -1), The y-intercept is -1
Slope form is y = mx + b. m is the slope, 1/3, and b is the y-intercept, -1
So the equation is: y = 1/3x -1

At : a.m. the angle of elevation of the sun for one city is . If the height of a monument is approximately , what is the length of the shadow it will cast at that time? Round to the nearest foot.
This question is incomplete, the complete question;
At 11:30 a.m. the angle of elevation of the sun for one city is 55.7°. If the height of a monument is approximately 555 ft, what is the length of the shadow it will cast at that time? Round to the nearest foot.
Answer:
the length of the shadow will be 379 ft
Step-by-step explanation:
Given the data in the question and as represented in the diagram below;
height of monument = 555 ft
angle of elevation = 55.7°
From the image below, this makes a right angled triangle
we know that the some of the interior angles of a triangle is 180
so
∠ABC + ∠BCA + ∠CAB = 180°
90° + 55.7° + ∠CAB = 180°
∠CAB = 180° - 145.7°
∠CAB = 34.3°
Now, using sine rule;
BC / sinA = AB / sinC
so we substitute
BC / sin( 34.3°) = 555 / sin( 55.7° )
BC / 0.563526 = 555 / 0.826098
we cross multiply
BC × 0.826098 = 0.563526 × 555
BC × 0.826098 = 312.75693
BC = 312.75693 / 0.826098
BC = 378.595 ≈ 379 ft
Therefore, the length of the shadow will be 379 ft
Which expression is equivalent to xy^2/9?
Answer:
[tex]xy^\frac{2}{9} = x*\sqrt[9]{y^2}[/tex]
Step-by-step explanation:
Given
[tex]xy^\frac{2}{9}[/tex]
Required
The equivalent expression (see attachment)
We have:
[tex]xy^\frac{2}{9}[/tex]
Split
[tex]xy^\frac{2}{9} = x*y^\frac{2}{9}[/tex]
Apply the following laws of indices
[tex]y^\frac{m}{n} = \sqrt[n]{y^m}[/tex]
So, we have:
[tex]xy^\frac{2}{9} = x*\sqrt[9]{y^2}[/tex]

A) work out the value of g.
Give your answer in standard form correct to three significant figures.
B) work out the new value of g. Give your answer in standard form correct to 3 significant figures. (M is increased by 8% and T is increased by 5%).
Answer:
4547.14
Step-by-step explanation:
m increased by %8 so it'll be
[tex]6.588 \times {10}^{ - 5} [/tex]
and t will be
[tex]1.785 \times {10}^{ - 6} [/tex]
so G =
[tex] \sqrt{ \frac{(6.588 \times {10}^{ - 5}) }{ {(1.785 \times {10}^{ - 6}) }^{2} } } [/tex]
G= 4547

A statistics teacher found that the average quiz score in her class is 86%, and the average test score in her class is 81%.
Which of the following is the best way to represent this data?
A. using a bar graph where one has a length of 86 units and one bar has a length of 81 units
B. using a square with a side length of 86 units and a square with a side length of 81 units
C. using a pie chart with one section labeled 86% and one section labeled 81%
D. using a cube with a side length of 86 units and a cube with a side length of 81 units
Answer:
A. using a bar graph where one has a length of 86 units and one bar has a length of 81 units
Step-by-step explanation:
Took the quiz. The usual.
The optimal method to represent this data is with a "bar graph", with one bar 86 units long and the other 81 units long. which is the correct answer that would be an option (A).
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
The best way to represent this data is using a "bar graph" where one bar has a length of 86 units and one bar has a length of 81 units.
This is because a bar graph is used to compare the sizes of different data points, and the length of each bar represents the value of the data point.
In this case, the average quiz score is 86% and the average test score is 81%, so the length of the bar representing the quiz score would be longer than the length of the bar representing the test score.
Thus, Option A correctly describes the use of a bar graph to represent the data, so it is the correct answer.

Answer:
m(∠y) = 64°
Step-by-step explanation:
From the figure attached,
m(∠e) = 90°
m(∠b) + 67° = 180° [Linear pair of angles]
m(∠b) = 180 - 67
= 113°
m(∠c) + 75° = 180° [Linear pair of angles]
m(∠c) = 105°
m(∠a) = m(∠d)
By the property of a polygon,
Sum of the interior angles of a polygon is given by,
Sum of interior angles = (n - 2) × 180°
Here, n = number of sides of the polygon
For n = 5,
Sum of interior angles = (5 - 2)×180°
= 540°
m(∠a) + m(∠b) + m(∠c) + m(∠d) + m(e) = 540°
2m(∠d) + 113° + 105° + 90° = 540°
2m(∠d) + 308 = 540°
2m(∠d) = 540 - 308
m(∠d) = 116°
m(∠d) + m(∠y) = 180°
m(∠y) + 116° = 180° [Linear pair of angles]
m(∠y) = 64°
Question 4-6. Earth is 93 million miles from the Sun. Pluto is 4.67 billion miles from the Earth.Calculate the ratio of the distance from Pluto to Earth to the distance from Earth to the Sun. Use scientific notation to calculate the ratio and express your answer in standard notation. (round to the hundredths place)
Answer:
PE/SE = 5.02×10¹
Step-by-step explanation:
Sun-Earth (SE) = 93×10⁶ miles
Pluto-Earth (PE) = 4.67×10⁹ miles
so, PE/SE = (4.67×10⁹) / (93×10⁶) = (4.67×10³)/93 =
= 50.215053763440860215... =
= 5.02×10¹ / 1 or simply 5.02×10¹
in other words, Pluto is a little bit more than 50 times farther away from Earth, than Earth is from the Sun.
