Answer:

9.57 ft²

Step-by-step explanation:

assuming the diigram attached is similar to the one required to complete the question,

From the diagram

Area of the window = Area of the rectangle+ Area of the semi circle.

A = lw+πr²/2................ Equation 1

Where A = area of the window, l = length of the rectangle, w = width of the rectangle, r = radius of the semi circle.

From the diagram,

Given: l = 4 ft, w = 2 ft, r = w/2 = 2/2 = 1 ft.

Constant: π = 22/7

Substitute these values into equation 1

A = (4×2)+(22/7×1²/2)

A = 8+1.57

A = 9.57 ft²

[tex]x_{v}[/tex]Answer:

The vertex of an up - down facing parabola of the formy = ax" + bx + c is xy =

The parabola params are:

a = 8, b = -14, c =3

[tex]x_{v}=b/2a[/tex]

[tex]x_{v}[/tex]=-(-14)/2·8

simplify

[tex]x_{v}[/tex]=-(-14)/2·8

[tex]x_{v} = 7/8[/tex]

Plug in [tex]x_{v}[/tex]=7/8to find the [tex]y_{v}[/tex] value

[tex]y_{v}[/tex]= -25/8

Therefore the parabola vertex is

(7/8 , -25/8)

If a < 0, then the vertex is a maximum value

If a > 0, then the vertex is a minimum value

a = 8

Minimum(7/8 , -25/8)

Answer:

Angle 1 - 51

Angle 2 - 39

Angle 3 - 90

Angle 4 - 51

Angle 5 - 17

Angle 6 - 129

Step-by-step explanation:

Angle 1 = 180 - 90 - 39 = 51

Angle 2 = 90 - Angle 2 (51) = 39

Angle 3 = 90

Angle 4 = 180 - Angle 2 (39) - Angle 3 (90) = 51

Angle 5 = 180- 90 - 34 -39 = 17

Angle 6 = 180 - Angle 4 (51) = 129

Answer:

[tex]x = 5[/tex]

[tex]y = 16[/tex]

Step-by-step explanation:

Given

See attachment for parallelogram

Required

Find variables x and y

Solving for x, we have:

[tex]5x = 25[/tex] ---- Opposite sides of a parallelogram

[tex]\frac{5x}{5} = \frac{25}{5}[/tex] ------ Divide both sides by 5

[tex]x = 5[/tex]

Solving for y, we have:

[tex]3y - 1 = 47[/tex] ---- Opposite sides of a parallelogram

[tex]3y = 1 + 47[/tex] ------ Collect like terms

[tex]3y = 48[/tex]

[tex]\frac{3y}{3} = \frac{48}{3}[/tex] ---- Divide both sides by 3

[tex]y = 16[/tex]

Answer:

triangle and trapezoid

Step-by-step explanation:

The correct answer is Option B) Rectangle

A solid  bounded by plane faces of which one, called the base, is a polygon and the other faces are all triangles meeting at a point outside the polygon.

Given here that the base of the pyramid is a rectangle and thus the plane slicing through the vertex along the perpendicular distance will result in two congruent rectangles at the base as the vertex projects on the midpoint of a rectangle.

Hence, the correct option is B)

Answer:

z/y

Step-by-step explanation:

The equation can be used to calculate the output values in the table is y = 2x.

A equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.

The equation can be used to calculate the output values in the table is determined in the following equation.

The equation is;

y = 2x

When the value of y = 4 the value of x is;

y = 2x

4 = 2x

x = 4/2

x = 2

When the value of y = 6 the value of x is;

y = 2x

6 = 2x

x = 6/2

x = 3

When the value of y = 8 the value of x is;

y = 2x

8 = 2x

x = 8/2

x =4

When the value of y = 10 the value of x is;

y = 2x

10 = 2x

x = 10/2

x = 5

Hence, the equation can be used to calculate the output values in the table is y = 2x.

Answer:

The approximate distance between points D and E is 8.25

Step-by-step explanation:

The figure is as follows :

To find - What is the approximate distance between points D and E ?

Solution -

By Pythagoras Theorem, we get

(DE)² = (FE)² + (DF)²

        = (8)² + (2)²

        = 64 + 4

        = 68

⇒(DE)² = 68

⇒DE = √68

⇒DE = 8.246

∴ we get

The approximate distance between points D and E is 8.25

Answer:

Question 2: x<-2

Question 6: 1.75 + 0.65m ≤ 10

Question 3: x ≥ -40

Question 4: Graph B

Step-by-step explanation:

Question 2:

since it needs to be greater than 11, we should add a number greater than 4 to seven. so it would be x>2. but since we are subtracting, we turn the 2 negative and flip the sign. Now it would be x<-2

Question 6:

the flat fee is 1.75 and they pay an additional 0.65 for every mile.

We know that the price has to be either less than or equal to 10. And the symbol is ≤. The inequality is 1.75 + 0.65m ≤ 10

Question 3 :

subtract 3 from both sides:

x/4 + 3 - 3 ≥-7 - 3

x/4≥-10

multiply each side by 4

x/4 * 4 ≥ -10 * 4

x ≥ -40

Question 4:

-3x-5 < -2

add 5 to both sides

-3x -5 + 5 < -2 + 5

-3x < 3

divide by -3

-3x / 3 < 3/3

x>-1

Answer:

look at the picture i have sent

Answer:

d

Step-by-step explanation:

this shape is made up of a triangular prism and a rectangular prism. the formula for the volume of a prism (any prism, doesn't matter) is base area times height. the base areas of the rectangular prism can be found by multiplying 4*12, as these are the dimensions of the base rectangle. 4*12=48. we now multiply this number by the height of the rectangular prism as shown in the volume of a prism formula. the height of the rectangular prism is 14, so 48*14=672. the volume of the rectangular prism is 672 cm^3.

now for the triangular prism. the bases of the triangular prism are the two triangle shapes on the ends; a prism is named after the shape of its base, so be sure to note that you use the triangles for the formula and not the rectangle on the bottom. to find the area of one of these bases (they are both the same), we use the triangle area formula, 1/2*base*height. the base of the triangle shape is 4 units long, as seen by the measurements of the rectangle this triangle sits on top of. to find the height of this triangle, which isn't given, we must use the pythagorean theorem, a^2+b^2=c^2. c in this case is equal to 4 as that is the hypotenuse, and a and b are interchangeable. since the pythagorean theorem only works for right triangles, we must cut the base length in half to assume that the final side is a vertical line, which will give us the height of the original triangle. (note: halving the base length in order to apply the pythagorean theorem only works in this case because both of the other sides are equal length, as we can see on the far triangle, so make sure this applies before trying it in another context) the halved base length is 2, and this number can be either a or b, doesn't matter because the formula adds them. so: (2)^2+b^2=4^2. 2^2 is 4, and 4^2 is 16. 4+b^2=16. subtract 4 from both sides, leaving you with b^2=12, and to get rid of the square on b you take the square root of both sides. so the height of this triangle is the square root of 12, which doesn't need to be simplified if you have a calculator that can process square root input. so to find the area of this triangle, we convert the equation 1/2*base*height into 1/2*4*square root of 12. this gets you about 6.93. to find the total volume of this prism, you multiply the base area times height. as we just figured out, the base area is 6.93, and the height is 12, because this is the length between the two bases, which are the triangles. so, 6.93*12=83.16 is the volume of the triangular prism. the final step is to add this to the volume of the rectangular prism, which is 672. 672+83.16= 755.16 cm^3.

I used Desmos to graph the function g(x)=4(1/4)^x+2

They have different y-intercepts because function f(x) is 4, while the y-intercept on graph is 6

Answer: 5/6 chance

Step-by-step explanation:

well on a six sided die there are the numbers : 1 , 2 , 3 , 4 , 5 , 6 obviously and we know that the total number of possible outcomes when you roll it would be six

rolling a 4 is only one option out of six so we subtract one from six

6 - 1 = 5

so theres a 5/6 chance you will not roll a 4

Answer:

D. 5

Step-by-step explanation:

We can triangle JHK is isosceles because two of its sides are radii, and radii of the same circle are always equal. Let the radius equal r. We can say that both JH and HK equal r because the extend from the center to the circle. We can set up the equation:

PJHK = JK + JH + HK

18 = 8 + r + r

10 = 2r

r = 5

Since HK equals r, it equals 5.
