Marsha sees an airplane flying overhead. The spot on the ground that is directly under the plane is 3,600 feet from Marsha's house. She sees the plane at a 45o angle of elevation. What is the elevation of the plane?
The elevation of the plane is 3600 ft
Let
h = elevation of plane, d = distance from Marsha's house to spot on ground below plane = 3600 feet and Ф = angle of elevation of plane = 45°From the triangle, we have the trigonometric ratio
tanФ = h/D
Elevation of the planeMaking h subject of the formula, we have
h = DtanФ
substituting the values of the variables into the equation, we have
h = DtanФ
h = 3600 ft × tan45°
h = 3600 ft × 1
h = 3600 ft
So, the elevation of the plane is 3600 ft

What is the distance between two points?Let the two points be A ( x₁ , y₁ ) and B ( x₂ , y₂ )
The distance from A to B is the same as the distance from B to A
Distance between two points is the length of the line segment that connects the two points in a plane.
The formula to find the distance between the two points is usually given by D = √( ( x₂ – x₁ )² + ( y₂ – y₁ )²)
This formula is used to find the distance between any two points on a coordinate plane or x-y plane
Given data ,
Let the distance between 2 points be represented as D
Now , let the first point be P ( -5 , 0 )
Let the second point be Q ( 1 , 0 )
Now , distance D = √( ( x₂ – x₁ )² + ( y₂ – y₁ )²)
On simplifying , we get
D = √ ( -5 - 1 )² + ( 0 )²
D = √ ( 6 )²
D = 6 units
Hence , the distance is 6 units

helpppp: Find the area of the figure.
Step-by-step explanation:
in such cases we always try to split the complex figure into non-overlapping simple figures, calculate their areas and add them up.
what simple figures can we see here ?
I see a rectangle 80m × 130m.
and that leaves for me a right-angled triangle in the upper right corner with the legs of
250-80 = 170 m and 130-50 = 80 m
the area of a rectangle is
length × width
the area of a right-angled triangle is
leg1 × leg2 / 2
the individual areas are
80×130 = 10,400 m²
170×80/2 = 170×40 = 6,800 m²
and that gives us a total for the whole area
10400 + 6800 = 17,200 m²

Explanation:
Use the triangle inequality theorem to set up these three inequalities
AB+BC > ACAB+AC > BCAC+BC > ABIf you were to apply substitution and solve for x, then you'd get these solutions in the order presented shown above
x < 11/2x > 3/4x > -3/4We'll ignore the third inequality. It's not very useful because we were already told that x > 0.
The first two inequalities combine to get 3/4 < x < 11/2
This is the range of possible x values so that triangle ABC is possible.
---------------
If we want angle CAB (or angle A for short) to be the largest of the triangle, then side BC must be the longest of the three sides.
The rule is: the largest angle is always opposite the longest side. This applies to triangles only.
Since BC is the longest side, this means BC > AB and BC > AC
---------------
Let's focus on the first inequality
BC > AB
x+7 > x+4
7 > 4
That's true regardless of what we pick for x. So BC is always longer than AB.
---------------
Now onto the second inequality
BC > AC
x+7 > 4x
7 > 4x-x
7 > 3x
3x < 7
x < 7/3
Now recall that we found earlier x > 3/4 or 3/4 < x
Combine 3/4 < x and x < 7/3 to get the compound inequality 3/4 < x < 7/3
---------------
Notice the middle part of that compound inequality is x and BC = x+7
If we were to add 7 to all three parts of the compound inequality, then we'll determine exactly the possible range of lengths for segment BC.
3/4 < x < 7/3
3/4+7 < x+7 < 7/3+7
3/4 + 28/4 < x+7 < 7/3 + 21/3
31/4 < x+7 < 28/3
31/4 < BC < 28/3
The length of segment BC is between 31/4 units and 28/3 units, excluding both endpoints. Those are the values of m and n in that order.
---------------
The last step is to compute n-m
n-m = (28/3) - (31/4)
n-m = (112/12) - (93/12)
n-m = (112-93)/12
n-m = 19/12 which points us to choice D.
Side note: 7/3 - 3/4 = 28/12 - 9/12 = (28-9)/12 = 19/12
Mr. Torres has a class of 17 students. He can spend $24 on each student to buy math supplies for the year. He first buys all of his students calculators, which
costs a total of $77.35. After buying the calculators, how much does he have left to spend on each student?
Answer:
She has a class of 17 kids. At $24 each, she can spend 17*$24 = $408. Since she spent $125.36, she has $408 - $125.36 = $282.64 left to spend.

Which of the following shows the Commutative Property of Multiplication?
(3 × 2) × 7 = 3 × (2 × 7)
4 × (5 + 8) = (4 × 5) + (4 × 8)
4 × 5 = 5 × 4
9 × 7 = 63
Answer:
The options that show the Commutative Property of Multiplication are:
A) 4x5=5x4
C) (3 x 2) × 7 = 3 ×(2 x 7)
------------------------------
The commutative property of multiplication states that the order in which the factors are multiplied does not change the product, that is:
Of the options, the ones which show it are:
A) 4x5=5x4
C) (3 x 2) × 7 = 3 ×(2 x 7)
In C), on the left side, the first 3 is multiplied by 2, then the result 6 is multiplied by 7, resulting in 42. On the right side, 2 is multiplied by 7, resulting in 14, which is multiplied by 3, resulting in 42.

y=3(x-2)(x-5) standard form?
Answer:
y = 3x² - 21x + 30Step-by-step explanation:
Given is the factored form of a quadratic function.
The standard form is:
y = ax² + bx + cOpen parenthesis to convert it into standard form:
y = 3(x - 2)(x - 5) = 3(x² - 7x + 10) = 3x² - 21x + 30Answer:
3x² - 21x + 30Step-by-step explanation:
Keep in mind that the equation in standard form is y = ax² + bx + c
[Where "a, b, and c" are the constants.]
Simplify the distibutive property:
⇒ y = 3(x - 2)(x - 5)
⇒ y = (3x - 6)(x - 5)
Simplifying the R.H.S using the rule (a + b)(c - d) = ac - ad + bc - bd:
⇒ y = (3x - 6)(x - 5)
⇒ y = (3x² - 15x - 6x + 30)
⇒ y = (3x² - 21x + 30)
⇒ y = 3x² - 21x + 30
If possible, reorganize the equation in standard form:
⇒ y = 3x² - 21x + 30 (In standard form)
A rectangular lot is 80 yards wide and 125 yards long.
Give the length and width of another rectangular lot that has the same perimeter but a smaller area.
Answer:
70 yards wide and 135 yards long
Step-by-step explanation:
The perimeter of a rectangle will be the same if the sum of length and width is the same. The area will be smaller if the difference between lenth and width is greater.
__
The sum of length and width will be the same if the length is increased by the same amount that the width is decreased. Changing each by 10 yards is one possibility.
A lot 70 yards wide and 135 yards long will have the same perimeter and a smaller area.
_____
Check
Given perimeter: 2(80 +125) = 410 yds.
Modified perimeter: 2(70 +135) = 410 yds. (same)
Given area = 80(125) = 10000 yd².
Modified area: 70(135) = 9450 yd². (smaller)
__
Additional comment
The area is greatest when the difference between the length and width is zero. That is, the rectangle will be a square.
Which of the following polyhedra have the same volume?
Select each geometry shape which have the same volume.
A.
A hemisphere with a radius of 2 cm.
B.
A sphere with a radius of 14 cm.
C.
A cone with a radius of 2 cm and a height of 4 cm.
D.
A cylinder with a radius of 13 cm and a height of 13 cm.
Answer:
A and C
Step-by-step explanation:
We can eliminate poor choices by estimating their relative sizes. And we can check the remaining choices by finding the exact volumes.
__
A hemisphere with radius 2, or a cone with dimensions of 4 or less, will have a much smaller volume than a sphere with radius 14. A cylinder with dimesions smaller than those of the sphere will have a smaller volume.
So, the only figures that might have similar volumes are the hemisphere and the cone.
HemisphereV = 1/2(4/3)πr³ = 2/3π(2 cm)³ = 16/3π cm³
ConeV = 1/3πr²h = 1/3π(2 cm)²(4 cm) = 16/3πcm³
__
The hemisphere (A) and the cone (C) have the same volume.
