Answer:
Part 1 : y = 0.75x
Part 2 : $750
Step-by-step explanation:
Part 1
Worst Buy, a local electronics store, advertises a sale price of 25% off all televisions 42" or bigger. Model the sales price (original price minus discount) of those televisions, y, as a function of the regular price of the tv, x.
Let y be the sales price of the tv and x its regular price. Since its sales price = regular price - discount, and our discount is 25% of the sales price, that is 0.25x, we have
sales price = regular price - discount
y = x - 0.25x
y = 0.75x
Part 2: If the regular price of a 60" television is $1000, use the equation you came up with in part 1 to find the sales price of the item
Since the sales price, y = 0.75x,and x = regular price = $1000,
substituting x into y, we have
y = 0.75x
y = 0.75($1000)
y = $750

Which shape shows the cross-section of the square pyramid when it is cut by a plane parallel to the base?
Answer:
Triangle
Step-by-step explanation:
A pyramid is a strong-solid shape that is comprised of triangles, square shapes, squares, and different polygons. Pyramids are arranged depending on the state of their base. For instance, the outline given is a square-based pyramid in light of the state of its base(which is a square). Different sorts incorporate the three-sided based pyramid, three-sided based pyramid, and other polygon-based pyramids.
In the event that this square pyramid is cut with a plane that is corresponding to the base of the pyramid, the state of its cross-area will be a triangle since the shapes that are corresponding to the base are altogether triangles. So slicing the plane corresponding to the base is like removing one side of the triangle making up the pyramid.

Answer:
[tex]\boxed{50cm^2}[/tex]
Step-by-step explanation:
Hello There!
The shown figure is a trapezoid
The formula for area of a trapezoid is
[tex]A=\frac{a+b}{2} h[/tex]
where a = base 1
b = base 2
h = height
the dimensions given are
13 & 7 - bases
5 - height
so all we have to do is plug in the values into the formula
[tex]A=\frac{7+13}{2} 5\\7+13=20\\\frac{20}{2} = 10\\10*5=50\\A=50[/tex]
So we can conclude that the area of the trapezoid is 50 cm²
Solve the following quadratic by using square root property. x2 + 16 = 0
A. X= 16 , x= -16
B x = 4, x= -4
C x= 4i , x= -4i
4)What kind of shape do the parametric equations make?X= 7sin(theta), y= 2cos(theta)
A) Circle
B) Ellipse
C) Square
D) Parabola
Answer:
Ellipse
Step-by-step explanation:
Given
[tex]x = 7sin\theta[/tex]
[tex]y= 2cos\theta[/tex]
Required
The kind of shapes with such equations
This answer to this question is(B) Ellipse
The parametric equation of an ellipse is represented as:
[tex]x = asin(\theta)[/tex] and [tex]y = bcos(\theta)[/tex]
In this case:
[tex]a=7\ b = 2[/tex]
So:
[tex]x = 7sin\theta[/tex] and [tex]y= 2cos\theta[/tex]

A deep sea diver started at sea level (0 feet) and dove at a rate of 5.6 feet per minute. If the diver dove for ½ hour, what rational number represents his position relative to sea level? Show your work. A. 168 feet B. 2.8 feet C. -2.8 feet D. -168 feet
Given:
A deep sea diver started at sea level (0 feet).
Rate of diving = 5.6 feet per minute.
Time = [tex]\dfrac{1}{2}[/tex] hour
To find:
The rational number that represents his position relative to sea level.
Solution:
We know that,
1 hour = 60 minutes
[tex]\dfrac{1}{2}[/tex] hour = 30 minutes
A deep sea diver, dove at a rate of 5.6 feet per minute.
Distance covered in 1 minute = 5.6 feet
Distance covered in 30 minute = 30 × 5.6 feet
= 168 feet
The diver dove 168 feet in [tex]\dfrac{1}{2}[/tex] hour. Since it is below the sea level, therefore it should be negative.
So, the rational number that represents his position relative to sea level is [tex]-168[/tex] feet.
Therefore, the correct option is D.

PLEASE HELP I WILL GIVE BRAINLEST, I need an answer that is 100% correct because this test determines if I'm passing or not, thank you.
Answer:
C = 150.72 cm
A = 1808.64 [tex]cm^{2}[/tex]
Step-by-step explanation:
circumference = 2π[tex]r[/tex]
r = 24 (48 ÷ 2)
substitute 24 for r
C = 2 × 3.14 × 24
C = 150.72
Area = π[tex]r^{2}[/tex]
r = 24
substitute 24 for r
A = 3.14 × [tex]24^{2}[/tex]
A = 3.14 × 576
A = 1808.64

Answer:
y=-2x+1
Step-by-step explanation:
First, you calculate the slope, which is rise over run: -9+5 / 5-3 = -2. Then, find b by substituting the coordinates (of either one point) into the slope-intercept formula, y = mx + b.
Answer:
Step-by-step explanation:
The slope intercept form of a line is
y=mx+b, where m=slope and b= y intercept
The slope of a line is defined as
m=(y2-y1)/(x2-x1), in this case we have points (3,-5) and (5,-9)
m=(-9-(-5))/(5-3)
m=-4/2
m=-2, so our line is now
y=-2x+b, using point (3,-5) we can now solve for b
-5=-2(3)+b
-5=-6+b
1=b so the completed line is
y=-2x+1
Drag the symbol to complete the solution to this inequality.
