Answer:
? = -1/2 dark gray box = - 1
y = -1/2 x - 1 or
y = -0.5x - 1
Step-by-step explanation:
The place to start is at 0.
When x = 0 then y = - 1
That means that the second box (the dark gray one) is - 1
So far what you know about the equation is
y = ?x - 1
We need to check two more points.
x = 4
y = - 3
- 3 = ? 4 - 1 Add 1 to both sides
-3 +1 = ?4 - 1 + 1 Combine The -1 and + 1 Cancel
-2 = ?4 Divide by 4
-2/4 = ?
? = -1/2 or - 0.5
Now we need 1 more point to check the result

1. The length of the altitude is 15 units.
2. The perimeter of trapezoid ABCD is 132 units.
Perimeter of a trapezoid.An altitude is the vertical height of a given object from the sea level. This is majorly a height reached by an object to the sea level as a reference.
The perimeter of a trapezoid is the sum of all its sides.
From the question;
1. To determine AE,
DE = (DG - EF)/ 2
= (22 - 6)/ 2 (since AB = EF = 6)
= 8
DE = 8 units
The altitude AE can be determined by applying the Pythagorean theorem to triangle ADE. So that;
/hyp/^2 = /opp/^2 + /adj/^2
AD^2 = DE^" + AE^2
17^2 = 8^2 + AE^2
289 = 64 + AE^2
AE^2 = 225
AE = 15
Thus the length of the altitude is 15 units.
2. To determine the perimeter of the trapezoid, we have;
AE = (AD - EF)/ 2
= (58 - 16)/ 2 (since BC = EF = 16)
= 21
AE = 21 units
So that from triangle ABE, applying the Pythagorean theorem to determine the value of AB, we have;
/hyp/^2 = /opp/^2 + /adj/^2
AB^2 = BE^2 + AE^2
= 20^2 + 21^2
AB = 841^1/2
AB = 29
Perimeter of the trapezoid = 29 + 16 + 29 + 58
= 132 units
Thus, the perimeter of the trapezoid is 132 units.

What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface.
The radius of cylinder is r=8 inches
Height is 0.5 feet.
Surface area of cylinder=2πr(r+h)
We know that 0.5feet=6 inches
Suface area of original cylinder=2πr(r+h)
=2×π×8(8+6)
=224π
Now the dimensions are doubled ,so r=16 inches , h=12 inches
Suface area of changed cylinder=2πr(r+h)
=2π×16(16+12)
=32π×(28)
=896π
=4(224π)
Hence by 4 factor the surface area is changed.

The perimeter of a rectangular field is 74 yards. The length of the field is 27 yards. What is the width in yard of the field
Answers
Answer:
width = 10 yds
Step-by-step explanation:
perimeter = 2L + 2W
74 = 2(27) + 2W
74 = 54 + 2W
subtract 54 from both sides of the equation:
2W = 20
divide both sides by 2:
W = 10
The width of the yard whose length is 27 yards and perimeter is 74 yards is evaluated to be 10 yards
How to find the perimeter of a rectangle?For a rectangle with length and width L and W units, we get:
Perimeter of the rectangle = [tex]2(L + W) \: \rm units[/tex]
For this case, let we assume that:
The width of the considered rectangular field = W yards
Then, as we're provided that:
Perimeter of the rectangular field = 74 yardsLength of the rectangular field = 27 yards.Putting these in the formula for perimeter of a rectangle, we get;
[tex]Perimeter = 2( L + W)\\74 = 2(27 + W)\\\\\text{Dividing both the sides by 2}\\\\\dfrac{74}{2} = \dfrac{2(27+W)}{2}\\\\37 = 27 + W\\\\\text{Subtracting 27 from both the sides}\\\\37 - 27 = W\\W = 10 \: \rm yards[/tex]
Thus, the width of the yard whose length is 27 yards and perimeter is 74 yards is evaluated to be 10 yards

The Science Club went on a two-day field trip. On the first day, the members paid $60 for transportation plus $15 per ticket to the planetarium. On the second day, they paid $95 for transportation plus $12 per ticket to the geology museum.
Write an expression to represent the total cost for two days for the ₙ members of the club.
Answers
Answer: Let n be the number of members in the Science Club.
On the first day, the total cost for transportation plus the cost of tickets is 60 + (15n) dollars.
On the second day, the total cost for transportation plus the cost of tickets is 95 + (12n) dollars.
So, the total cost for both days is (60 + 15n) + (95 + 12n) = 155 + 27n dollars.
The expression to represent the total cost for two days for the n members of the club is 155 + 27n dollars.
This equation represents the total cost for the transportation, planetarium and geology museum for 2 days for the n members in the club.
It should be noted that this is the monetary representation and it might vary depending on other factors, such as group discounts.
Step-by-step explanation:
Answer:
(n x 27)+155
Step-by-step explanation:
15 +12 = 27
Each member pays $27 for the tickets so we multiply it by the number of members.
95 + 60 = 155
The members pay $155 in total for transportation.

According to the question the angle between right angle triangle hence the M∠1 = [tex]90^{0}[/tex] .
What does a triangle's right angle look like?90 degrees or a straight angle is always one angle. The hypotenuse is the side that has an angle of 90° on it. Always, the hypotenuse is the longest side. The remaining two inner angles add up to a total of 90°.
Which three angles make up a right triangle?Right triangles are triangles with one of the internal angles at a right angle of 90 degrees. Since a triangle's three interior angles sum up to 180 degrees, a right triangle's three interior angles must always add up to 90 degrees since one of them is always 90 degrees (they are complementary).

Suppose your cousin missed class and asks you, “Why do we plug in 0 for x to find y-intercepts and 0 for y to find x-intercepts? That doesn’t make sense to me.” Explain to your cousin WHY this process works. Use the line
5x+4y=14 as an example.
A) A description in words why this works
Answers
The reason why the cousin's procedure for getting the x and y intercepts work is because they represent the definition of those points on a graph.
How to find the x and y intercepts?The x-intercept of a graph or function simply refers to the point at which the graph crosses the graph crosses the x-axis or the point at which y = 0. In a similar manner, the y-intercept simply refers to the point at which the graph crosses the y-axis or simply the point at which x = 0.
Now, we are given the equation of the line as;
5x + 4y = 14
The general form of equation of a line in slope intercept form is;
y = mx + c
where;
m is slope
c is y-intercept
Rewriting the equation of the line in slope intercept form is;
y = -⁵/₄x + ⁷/₂
Now, the reason why we plug in 0 for x to get the y-intercept is because when x = 0, that is only where we can get the y-intercept as the corresponding value of x will be traced to 0.
Similarly, the reason why we plug in 0 for y to get the x-intercept is because when y = 0, that is only where we can get the x-intercept as the corresponding value of y will be traced to 0.

Answers
Answer:
75°Step-by-step explanation:
We know that:
sin 30° = 1/2, therefore arcsin (1/2) = 30°tan 45° = 1, therefore arctan (1) = 45°So the value of the expression is:
arcsin (1/2) + arctan (1) = 30° + 45° = 75°Answer:
75°
Step-by-step explanation:
Recall the common trigonometric angles:
[tex]\sin 30^{\circ}=\dfrac{1}{2}[/tex]
[tex]\tan 45^{\circ}=1[/tex]
Arcsin is the inverse of sin.
Arctan is the inverse of tan.
[tex]\implies \arcsin \left(\dfrac{1}{2}\right)=30^{\circ}[/tex]
[tex]\implies \arctan (1) = 45^{\circ}[/tex]
Therefore:
[tex]\implies \arcsin \left(\dfrac{1}{2}\right)+\arctan (1) = 30^{\circ}+ 45^{\circ}=75^{\circ}[/tex]
A square photograph is printed on a larger rectangular sheet of paper leaving a border around the
photograph of 2 centimeters on the top and 3 centimeters on each of the remaining sides. The sheet of paper
has an area of 72 square centimeters. If x is the length of a side of the photograph measured in centimeters,
which of the following equations could be used to find x ?
Answers
The area of a shape is the amount of space, the shape can occupy. The equation to calculate the value of x is: [tex](e)\ x^2 + 11x -42= 0[/tex]
The space on the border is given as:
[tex]Top = 2[/tex]
[tex]Others = 3[/tex]
So, the dimension of the sheet of paper is:
[tex]Length = x + 2 + 3[/tex]
[tex]Length = x + 5[/tex]
[tex]Width = x + 3 + 3[/tex]
[tex]Width = x + 6[/tex]
The area of the sheet is then calculated as follows:
[tex]Area= Length \times Width[/tex]
[tex]Area= (x + 5) \times (x + 6)[/tex]
Open brackets
[tex]Area= x^2 + 5x + 6x + 30[/tex]
[tex]Area= x^2 + 11x + 30[/tex]
From the question, we understand that the area of the sheet is [tex]72cm^2[/tex]
So, the equation becomes
[tex]x^2 + 11x + 30 = 72[/tex]
Subtract 72 from both sides
[tex]x^2 + 11x + 30 -72= 0[/tex]
[tex]x^2 + 11x -42= 0[/tex]
Hence,
[tex](e)\ x^2 + 11x -42= 0[/tex] can be used to calculate the value of x
