Determine two pairs of polar coordinates for the point (5, -5) with 0° ≤ θ < 360°
Answer:
Step-by-step explanation:
x=5
y=-5
Hence it lies in 4th quadrant.
x=r cos θ
5=r cos θ ...(1)
y=r sin θ
-5 =r sin θ ... (2)
square and add
(5)²+(-5)²=r²(sin ²θ +cos ²θ )
r²=25+25=50
r=±5√2
dividing
tan θ=-5/5=-1=-tan 45°=tan (180-45),tan(360-45)
θ=135°,315°
so polar coordinates are (5√2,315°) and (-5√2,135°)

What is the exact volume of the cone? with a 5 ft radius and a 16 ft height
Answer:
The volume is 418.93 ft^3
Step-by-step explanation:
Here, we want to find the volume of a cone
Mathematically, we use the formula;
V = 1/3 * pi * r^2 * h
r = 5 ft
h = 16 ft
Substituting these values;
V = 1/3 * 3.142 * 5^2 * 16
V = 418.93 ft^3

(-5,6) 5x+y=10 in slope intercept form
(-5 , 6) 5x + y = 10
⤸
y = 5.6 * 5x = 10
step-by-step:I. move the expression to the right
y = 10 + 5.6 * 5x
II. reorder the terms
y = 5.6 * 5x + 10

a collector purchased a rare book for $97.56 and then sold the book in an online auction for $141.82. The auction charged the collector $8.25 in fees for the use of its service. how much did the collector earn by selling the book
Answer:
$36.01
Step-by-step explanation:
141.82 - 8.25 = 133.57
133.57-97.56=36.01
The collector earned a total of $36.01 by selling the book.
What is the Subtraction operation?Subtraction is a mathematical operation that deducts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
The collector earned $141.82 - $97.56 = $44.26 by selling the book.
To find the total amount the collector earned, we need to subtract the price they paid for the book from the price they sold it for. This gives us the profit that the collector made on the sale of the book.
However, we also need to subtract the auction fees that the collector had to pay.
The collector paid $8.25 in fees, so their total earnings from the sale of the book were :
⇒ $44.26 - $8.25
Apply the subtraction operation, and we get
⇒ $36.01.
Therefore, the collector made a total of $36.01.

Bryans gocket team is purchasing jersys. The company charges $250 for the onetime set-up fee and $23 for each printed jersey which expression repressents the total cost of x number for the team
Given:
The company charges $250 for the onetime set-up fee and $23 for each printed jersey.
To find:
The expression that represents the total cost of x number for the team.
Solution:
We have,
Fixed charges = $250
Additional charges = $23 per printed jersey
Let x be the number of printed jersey. Then,
Additional charges = $23x
Total chargers = Fixed charges + Additional charges
= $(250 + 23x)
Therefore, the expression for the total charges is $(250 + 23x).
find the volume and the total surface area of a cuboide whose dimension 2m, 80cm and 60cm
Answer:
Volume= 0.96m^3
TSA= 6.56m^2
Step-by-step explanation:
Given data
Length = 2m
Width= 80cm= 0.8m
Height= 60cm= 0.6m
Volume= L*W*H
Volume= 2*0.8*0.6
Volume= 0.96m^3
TSA=2lw+2lh+2hw
TSA= 2*2*0.8+2*2*0.6+2*0.6*0.8
TSA= 3.2+ 2.4+ 0.96
TSA= 6.56m^2

-3(2+6x) +7x
Answer:
x = -17
Step-by-step explanation:
To simplify, we need to solve within the parentheses first:
-3(2 + 6x) + 7x
(-6 - 18x) + 7x
Next, we combine like terms:
-6 - 18x + 7x
-6 - 11x
Next, we isolate the variable "x":
-6 - 11x
/x
-6 - 11 = x
Combine like terms:
x = -17
