Use the figure to answer exercises 6-7. 8 ft 5 ft 6. Frank drew a square pyramid and its net to represent a fort. Complete the net by filling in the missing measure. Choose the correct answer below. OA. ОВ. OC. OD. 1.25ft 42.5ft 18 ft 5 ft 0 LA CA 5ft 1.25ft 8 ft 2.5ft
Answer:
6. C
7. 105 ft²
Explanation:
The square pyramid has a square base with a side's length equal to 5 ft and a slant height equal to 8 ft.
Now, the only option that shows a square with a side length equal to 5 is C. So, the right net is C.
Then, the amount of fabric depends on the area of the net. The area of the net is equal to the area of the square added to the area of the triangles.
The area of the square is:
Area = side x side = 5 x 5 = 25 ft²
The area of the triangles is:
Area = 1/2 x base x height = 1/2 x 5 x 8 = 20 ft²
Then, the total area of the net is:
Total Area = 25 ft² + 4( 20 ft²)
Total Area = 25 ft² + 80 ft²
Total Area = 105 ft²
So, Frank needs 105 ft² of fabric to make the fort.
What is the product of 3x^2 and 2x^3y+5xy^4 ?
The product of two expressions can be calculated using distributive property as,
[tex](2x^3y+5xy^4)(3x^2)=2x^3y\times3x^2+5xy^4\times3x^2[/tex](Distributive property (A+B)C=AC+BC) )
[tex]\begin{gathered} (2x^3y+5xy^4)(3x^2)=6x^{3+2}y+15x^{1+2}y^4 \\ =6x^5y+15x^3y^4 \end{gathered}[/tex]Therefore, the product of the expressions is,
[tex]6x^5y+15x^3y^4[/tex]Write an equation of a parabola with a vertex at the origin and a diretrix at y=5.
The equation of the parabola with a vertex at the origin and a directrix at; y = 5 as described in the task content is; x² = -20y.
How to write equation of a parabola with a vertex at the origin?It follows from the task content that the vertex of the parabola is at the origin while it's directrix is the line; y = 5.
Therefore, it follows that the focus of the parabola is; f = -5, since; (f - k) = (k - 5) where, k = 0.
Ultimately, a = 1/4(f-k).
a = 1/4(-5-0) = -1/20.
Recall, the vertex form equation of a parabola takes the form;
y = a(x - h)² + k; where (h, k) is the vertex.
Therefore, since the vertex is at the origin; we have;
y = (-1/20) (x -0)² + 0
y = -x²/20
20y = -x²
Ultimately, the required equation of the parabola is;
x² = -20y.

Answer:
[tex]y = -\frac{1}{20} x^{2}[/tex]
Step-by-step explanation:
[tex]y = \frac{1}{4(f-k)}(x - h)^{2} + k[/tex] Use the equation of the parabola. The vertex is at the origin, then (h, k) is (0, 0). Substitute 0 for h and k in the equation.
[tex]y = \frac{1}{4(f-0)} (x-0)^{2} + 0[/tex] Simplify.
[tex]y = \frac{1}{4f} x^{2}[/tex]
The directrix is given [tex]y = 5[/tex]. The distance from the focus to the vertex equals the distance from the vertex to the directrix, so
[tex]f - k = k - 5\\f = -5[/tex] Substitute -5 for f in the equation of the parabola above.
[tex]y = \frac{1}{4 * - 5} x^{2}[/tex] Simplify.
[tex]y = - \frac{1}{20} x^{2}[/tex]

Here from given question we have,
Measure of ∠2 = x + 85
And the measure of another angle = 73
From given picture,
Two sides of triangle are equal then the given triangle will be an Isosceles triangle
As we know in a Isosceles triangle the angles made by the two equal sides with 3rd side will be equal
=> ∠2 = 73

What is the unitary method?The unitary approach, to put it simply, is used to determine the value of a single unit from a specified multiple. How to determine the worth of a single pen, for instance, if 40 pens cost Rs. 400. The unitary approach can be utilized. Additionally, after determining the value of a single unit, we can multiply it to determine the value of the other units. Most ratio and proportion concepts are addressed using this methodology. To compute the value of other units using the unitary approach, the value of a unit quantity must first be determined. This can be varied in two different ways.
