If sin θ>0 and tan θ<0, in which quadrant does the terminal side of θ lie?
Answer:
Quadrant IV
Step-by-step explanation:
For an angle in the fourth quadrant the point P has positive x coordinate and negative y coordinate. Therefore: In Quadrant IV, cos(θ) > 0, sin(θ) < 0 and tan(θ) < 0 (Cosine positive). The quadrants in which cosine, sine and tangent are positive are often remembered using a favorite mnemonic.
Beth is selling tickets for a dinner at her school.
* Adult's tickets cost $6.00 each
Children's tickets cost $4.50 each
* Beth sold a total of 520 tickets
* Beth's ticket sales totaled $2,707.50.
How many tickets of each type were sold?
A. 245 children's tickets, 275 adult's tickets
B. 257 children's tickets, 263 adult's tickets
C. 260 children's tickets, 260 adult's tickets
D. 275 children's tickets, 245 adult's tickets
Answer:
D
Step-by-step explanation:
check each child answer and multiply by 4.50
check each adult answer and multiply by 6.00
add both answers up
and see which one it is
its not A, B, or C
Answer:
D
Step-by-step explanation:
x-number of children's tickets sold
y-number of adult's tickets sold
x+y=520=>x=520-y
4.5x+6y=2 707.5
45x+60y=27 075
45(520-y)+60y=27 705
15y+23 400=27 705
15y=3 675
y=245=>x=520-y=520-245=275

$85 bill before tax
Discount:25%
Tax:6.4%
Answer:
$67.83
Step-by-step explanation:
Price before tax: $85
Discount: 25%
100% - 25% = 75% = 0.75
Price after discount: 0.75 * $85 = $63.75
Tax: 6.4%
100% + 6.4% = 106.4% = 1.064
Price after discount & tax: 1.064 * $63.75 = $67.83
Answer: $67.83

Suppose y varies directly with x when x is 4, y is 32. What is y when x is -2
Step-by-step explanation:
Since y varies directly with x,
y = kx, where k is a real constant.
When x = 4, y = 32.
=> (32) = (4)k, k = 8.
Therefore when x = -2,
y = kx = (8)(-2) = -16.
The graph of p = 400 and the graph of p = 50s - 200 intersect at the point (12,400). If the equation p = 50s - 200 represents the profit, p, based on s sales, what does the intersection best represent? Show work.
Answer:
This shows that the profit for 12 sales is 400
Step-by-step explanation:
If both graphs intersects then;
p = p
400 = 50s - 200
50s = 400+200
50s = 600
s = 600/50
s = 12
Substitute s =12 into p = 50s-200
p = 50(12) - 200
p = 600-200
p = 400
Hence the intersection (s, p) is (12, 400)
This shows that the profit for 12 sales is 400

Factor: 16w3 – u4w3
Answer:
w^3(4 + u^2)(2 + u)(2 - u)
Step-by-step explanation:
6w^3 – u^4w^3
w^3(16 – u^4)
w^3(42 - ((u^2)^2)
w^3(4 + u^2)(4 - u^2)
w^3(4 + u^2)(22 - u^2)

It’s algebra it says find each function value here is a picture of the work sheet
1.
8 > 1 so: a(x) = -4x + 7
a(8) = - 4(8) + 7 = - 32 + 7 = - 25
2.
-6 ≤ 1 ≤ 1 so: a(x) = 2x - x²
a(1) = 2(1) - (1)² = 2 - 1 = 1
3.
-7 ≤ -6 so: a(x) = |x - 8|
a(-7) = |-7 - 8| = |-15| = 15
4.
-6 ≤ -3 ≤ 1 so: a(x) = 2x - x²
a(-3) = 2(-3) - (-3)² = -6 - 9 = - 15
5.
-6 ≤ -¹/₂ ≤ 1 so: a(x) = 2x - x²
a(-¹/₂) = 2(-¹/₂) - (-¹/₂)² = - 1 - ¹/₄ = - 1¹/₄
6.
⁹/₄ > 1 so: a(x) = -4x + 7
a(⁹/₄) = - 4(⁹/₄) + 7 = - 9 + 7 = - 2

What is the measure of the angle in red?
Answer:
B
Step-by-step explanation:
The red line is almost 360 degrees.
If you subtract 65 from 360 you get 295
When two straight lines or rays intersect at a shared endpoint, an angle is generated. The measure of the angle in red is 295°. The correct option is B.
What is an angle?When two straight lines or rays intersect at a shared endpoint, an angle is generated. An angle's vertex is the common point of contact. Angle is derived from the Latin word angulus, which means "corner."
The total angle at a point is always equal to 360°. Given that the measure of the green angle is 65°.
But as it can be seen that the red angle and the green angle together form a complete rotation of 360°. Therefore, the sum of the two angles can be written as,
Red angle + Green angle = 360°
Red angle + 65° = 360°
Red angle = 360° - 65°
Red angle = 295°
Hence, the measure of the angle in red is 295°.

The circumference is 25 pi What is the diameter?
Answer:
d=25
Step-by-step explanation:
d=C/Pi
d=25pi/pi
d=25
Answer:
Diameter = 25
Step-by-step explanation:
The circumference of a circle is 25 pi
Circumference of a circle is given by,
C = 2πr
25π = 2πr
Dividing both sides by 2π
[tex]\frac{25\pi}{2\pi}=\frac{2\pi r}{2\pi}\\\\12.5 = r\\[/tex]
Diameter = 2r
Diameter = 2(12.5)
Diameter = 25
