A 5.5 foot tall woman is standing 14 feet from a streetlamp casts a six foot shadow. How high is the lamp?
Answer:
The height of the lamp is 18.33 ft
Step-by-step explanation:
We can think in two triangle rectangles, one with cathetus of:
5.5ft and 6ft (the one formed by the woman ad her shadow)
And another triangle with cathetus equal to:
6ft + 14ft (the distance between the end of the shadow and the lamp)
And the other cathetus is the height of the lamp, H.
As bot triangles will share an angle (the one formed by the end of the shadow and the hypotenuse) then the triangles are equivalent, so the quotient between their cathetus will be equal, this is:
H/(6ft + 14ft) = 5.5ft/6ft
H/(20ft) = 5.5ft/6ft.
H = (5.5ft/6ft)*20ft = 18.33 ft

(40 B Points) Point A is located at coordinates -4,3 What are the coordinates of each point? Point B is the image of A after a rotation of 180 degrees using 0,0 as center. Point C is the image of A after a translation two units to the right, then a reflection using the x-axis. Point D is the image of A after a reflection using the y-axis, then a translation two units to the right.
I need this same question ughh
Coordinates of the points B, C and D will be (4, -3), (-2, -3) and (6, 3) respectively.
Rules for the transformation: If a point P(x, y) is rotated by 180° about the origin (0, 0),Rule for the transformation will be,
P(x, y) → P'(-x, -y)
If a point P(x, y) is shifted 'a' units left and 'b' units upwards,Rule for the transformation will be,
P(x, y) → P'(x - a, y + b)
If a point P(x, y) is reflected across y-axis,Rule for the transformation will be,
P(x, y) → P'(-x, y)
By using these rules,
"If a point A(-4, 3) is rotated 180° about the center (0, 0)"
Rule for the transformation,
P(x, y) → P'(-x, -y)
A(-4, 3) → B(4, -3)
"If a point A(-4, 3) is translated 2 units right and then reflected across x-axis."
Rule for the transformation,
P(x, y) → P'[(x + a), -y]
A(-4, 3) → C[(-4+2), -3]
→ C(-2, -3)
"If a point A(x, y) is reflected across y-axis, then translated by 2 units to the right"
Rule for the transformation,
P(x, y) → P'[(-x + a), y]
A(-4, 3) → D[(4 + 2, 3]
→ D(6, 3)
Therefore, coordinates of the points B, C and D will be (4, -3), (-2, -3) and (6, 3) respectively.

Y is the midpoint of XZ. X has coordinates (2, 8), and Y has coordinates (–3, 10). Find the coordinates of Z.
Answer:
The coordinates of Z is (-8,12)
Step-by-step explanation:[tex]\frac{2+x^{2} }{2}= -3 \\\frac{8+y^{2} }{2} = 10[/tex]
You multiply -3 by 2 to get -6 then multiply 10 by 2 to get 20
then you create the equations [tex]2+x^{2} =-6\\8+y^{2} =20[/tex] you subtract 2 by -6 and you get -8 (x coordinate) and you subtract 8 by 20 to get 12 (y coordinate)
To check your answer you use the Midpoint formula [tex](\frac{x^{1}+ x^{2} }{2} )(\frac{y^{1}+y^{2}}{2}) =M[/tex]
[tex]\frac{2+-8}{2} =\frac{-6}{2} = -3\\\frac{8+12}{2} =\frac{20}{2} =10[/tex] and you get your midpoint.

What is the area of the triangle?
(-6,3)
(-3,-5)
(-1,3)
Hey there! I'm happy to help!
To find the area of a triangle you multiply the base by the height.
We see that our base is 5 units long because it stretches from -6 to -1 on the coordinate plane. Our height is 8 because the y value goes from 3 to -5.
To find the area of a triangle, you just multiply the base by the height then divide by 2.
5(8)=40
40/2=20
The area is 20 square units.

Natasha makes on online purchase of 3 hard cover books for $19.95 each and 1 book on tape for $17.43. The site says that taxes paid by the customer are 7.25% of the total purchase price. Shipping charges are based on the following table: Amount of Purchase Standard Shipping Express Shipping up to $50 $5.10 $7.00 $50 up to $100 $6.35 $8.20 $100 up to $200 $7.80 $11.60 $200 and over $10.50 $16.45 Natasha selects standard shipping for her purchase and the company bills her credit card $91.08 for the total of the online purchase. Determine if Natasha has been billed correctly for her purchase. a. Natasha has been billed correctly. b. Natasha has not been charged enough for her purchase. c. Natasha has been over charged by $1.85 for her purchase. d. Natasha has been over charged by $8.20 for her purchase.
Answer:
C. Natasha has been charged by $1.85 for her purchase.
Step-by-step explanation:
Natasha has been over charged by $1.85 for her purchase. The correct option is - c. Natasha has been over charged by $1.85 for her purchase
Calculating the bill of a purchaseFrom the question, we are to determine if Natasha has been billed correctly for her purchase
From the given information,
She purchased
3 hard cover books for $19.95 each
3 × $19.95 = $59.85
and
1 book on tape for $17.43
1 × $17.43 = $17.43
Total purchase = $59.85 + $ 17.43
= $77.28
But, the site says that taxes paid by the customer are 7.25% of the total purchase price
∴ The tax Natasha would pay = 7.25% × $77.28
= 0.0725 × $77.28
= $5.60
Add to the total purchase,
Present bill = $77.28 + $5.60
Present bill = $82.88
Then, she selects standard shipping.
According to the shipping charges,
For amount of purchase between $50 - $100, Standard shipping costs $6.35
∴ Total bill = $82.88 + $6.35
Total bill = $89.23
But, the company bills her credit card $91.08
Since, $91.08 is more than her total bill, $89.23, then, Natasha has been over charged.
$91.08 - $89.23 = $1.85
Hence, Natasha has been over charged by $1.85 for her purchase. The correct option is - c. Natasha has been over charged by $1.85 for her purchase.
