Step-by-step explanation:

If PK and PF are tangent to the circle, then the radii OK and OF are perpendicular to the lines PK and PF respectively.

Consider quadrilateral PFOK. The sum of the measures of all interior angles in quadrilateral PFOK is equal to 360°. Since OK and OF are perpendicular to the lines PK and PF, you have that

∠FOK+90°+∠KPF+90°=360°,

∠FOK=360°-90°-90°-∠KPF=180°-∠KPF.

Angles FOK and KOE are supplementary angles, then

∠KOE=180°-∠FOK=180°-(180°-∠KPF)=∠KPF.

Since angle KOE is central angle, the arc EK has the same measure as angle KOE and as angle KPF.

Given [tex]\(PK\) and \(PF\)[/tex] tangents to circle [tex]\(O\),[/tex] angles [tex]\( \angle P \) and \( \angle EK \)[/tex] are equal by the properties of tangents.

To prove that [tex]\( m\angle P = m\angle EK \)[/tex] given the diagram, we can use properties of tangents and circles. Here is a step-by-step proof:

1. Identify the given information:

  - [tex]\( PK \) and \( PF \)[/tex] are tangents to circle [tex]\( k(O) \) at points \( K \) and \( F \),[/tex] respectively.

  - [tex]\( O \)[/tex] is the center of the circle.

  - [tex]\( PK \) and \( PF \)[/tex] are tangent to the circle, meaning they touch the circle at exactly one point.

2. Use properties of tangents:

  - A tangent to a circle is perpendicular to the radius at the point of tangency.

  - Thus, [tex]\( OK \perp PK \) and \( OF \perp PF \).[/tex]

3. Mark the right angles:

[tex]- \( \angle OKP = 90^\circ \)[/tex]

[tex]- \( \angle OFP = 90^\circ \)[/tex]

4. Connect the points to form a triangle:

  - Draw the line segment [tex]\( OP \).[/tex]

5. Use the exterior angle theorem:

  - In [tex]\(\triangle OKP\),[/tex] [tex]\( \angle OPK \)[/tex] is an exterior angle for [tex]\(\angle OKP\) and \(\angle PKO\).[/tex]

  - Since [tex]\( \angle OKP = 90^\circ \)[/tex] and [tex]\(\angle PKO\)[/tex] is another angle in the triangle, we have:

[tex]\[ \angle OPK = 180^\circ - (\angle OKP + \angle PKO) = 180^\circ - (90^\circ + \angle PKO) = 90^\circ - \angle PKO. \][/tex]

6. Similarly, in [tex]\(\triangle OFP\):[/tex]

  -[tex]\( \angle OFP = 90^\circ \) and \(\angle PFO\)[/tex] is another angle in the triangle.

  - Using the same logic as before:

[tex]\[ \angle OEP = 180^\circ - (\angle OFP + \angle PFO) = 180^\circ - (90^\circ + \angle PFO) = 90^\circ - \angle PFO. \][/tex]

7. Note that [tex]\( \angle OKP = \angle P \)[/tex] and [tex]\( \angle OFP = \angle EK \):[/tex]

  - By the property of the tangents from the same external point, [tex]\( PK = PF \).[/tex]

  - [tex]\( \angle PKO \) and \( \angle PFO \)[/tex] are complementary to [tex]\(\angle P\)[/tex] and [tex]\(\angle EK\)[/tex] respectively.

Therefore, it follows that:

[tex]\[ m\angle P = m\angle EK \][/tex]

Thus, the proof is complete.

Step-by-step explanation:

Let p be the store's cost (cost to buy the product wholesale).

Then the selling price is p + markup, or

                                         p + 0.80p = 1.80 p

and this comes to $21.60.

Dividing $21.60 by 1.80 results in p = $12.

The cost to the store is $12.

Answer:

(f º f)(3) = 30, when f(x) = x² - x

Step-by-step explanation:

This is a great example of composite functions and how to multiply one function by another.  (f º f) really means f(f(x)), or replacing every x in the original function f(x) with the function f(x).

Step 1: State the original function.

[tex]f(x) = x^{2} -x[/tex]

Step 2: Insert the function f(x) wherever there is an x.

[tex]f(f(x))=(x^{2} -x)^{2} -(x^2-x)[/tex]

Step 3: Expand anything that has an exponent. Remember: [tex](x+y)^2 = (x+y)(x+y)[/tex]

[tex]f(f(x))=(x^{2} -x)(x^{2} -x) -(x^2-x)[/tex]

Step 4: Foil the parts of the equations in brackets by multiplying the first terms, outside terms, inside terms and last terms in each bracket.

[tex]f(f(x))=(x^{4}-x^3-x^3+x^{2}) -(x^2-x)[/tex]

Step 5: Now you can remove the brackets (don'f forget to switch the symbols for the second brackets because you are subtracting) and sum the like terms.

[tex]f(f(x))=x^{4}-x^3-x^3+x^{2} -x^2+x[/tex]

[tex]f(f(x))=x^{4}-2x^3+x[/tex]

Step 6: Finally, substitute the given x value, which is 3, into the new equation.

[tex]f(f(x))=(3)^{4}-2(3)^3+(3)[/tex]

[tex]f(f(x))=81-54+3[/tex]

[tex]f(f(x))=30[/tex]

Therefore the answer is (f º f)(3) = 30.

Answer:

30

Step-by-step explanation:

Method 1:

ƒ(x) = x² - x

(f∘f)(x) = f(f(x)) = f(x²-x) = (x² - x)² - (x² - x) = x⁴ - 2x³ + x² - x² + x =  x⁴ - 2x³ + x

(f∘f)(3) = 3⁴ - 2(3)³ + 3 = 81 - 54 + 3 = 30

Method 2:

f(3) = 3² - 3 = 9 - 3 = 6

(f∘f)(3) = f(f(3)) = f(6) = 6² - 6 = 36 - 6 = 30

Simplifying

0.5p + -3.45 = -1.2

Reorder the terms:

-3.45 + 0.5p = -1.2

Solving

-3.45 + 0.5p = -1.2

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '3.45' to each side of the equation.

-3.45 + 3.45 + 0.5p = -1.2 + 3.45

Combine like terms: -3.45 + 3.45 = 0.00

0.00 + 0.5p = -1.2 + 3.45

0.5p = -1.2 + 3.45

Combine like terms: -1.2 + 3.45 = 2.25

0.5p = 2.25

Divide each side by '0.5'.

p = 4.5

Simplifying

p = 4.5

The value of p from the given equation is 4.5.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation is 0.5p-3.45=-1.2

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

The equation can be solved as follows

0.5p-3.45=-1.2

0.5p= -1.2+3.45

0.5p= 2.25

p= 2.25/0.5

p= 4.5

Therefore, the value of p is 4.5.

3(p + 2q)(p + 3q)

Step-by-step explanation:

Factor out 3 from each term

3(p² + 5pq + 6q²) ← factor the quadratic by

Consider the factors of the q² term which sum to give the coefficient of the pq- term

The factors are + 2 and + 6, since

2 × 3 = 6 and 2 + 3 = 5, hence

3p² + 15pq + 18q²

= 3(p + 2q)(p + 3q)

The quadratic expression [tex]3p^2+15pq+18q^2[/tex] can be factorized by first taking out a factor of 3, then factorizing the remaining quadratic expression. The result is 3(p+2q)(p+3q).

To answer your question about factorizing the quadratic expression [tex]3p^2+15pq+18q^2,[/tex] it's important we understand the factorization process.

First, we can take out a factor of 3.
So,[tex]3p^2+15pq+18q^2[/tex] = 3([tex]p^2+5pq+6q^2[/tex])

Now, we factor the quadratic expression [tex]p^2+5pq+6q^2.[/tex]
To factor it, we need to look for two numbers that multiply to 6 and add to 5. The numbers 2 and 3 fulfill this property. Therefore, we can write [tex]p^2+5pq+6q^2[/tex] = (p+2q)(p+3q)

So the factorization of the original expression is 3(p+2q)(p+3q)

Step-by-step explanation:

The volume of a pyramid of base area A and height h is

V = (1/3)(A)(h).

Here,

V = (1/3)(6 in)²(12 in) = 144 in³

The volume of the given pyramid with a square base whose side measures 6 inches and the altitude of the pyramid measures 12 inches is 144 cubic inches. The value is obtained by applying the formula for the volume of the pyramid as  [tex]\frac{1}{3} B_{A}h[/tex].

The volume of the pyramid is given by the formula:

[tex]V=\frac{1}{3} B_{A}h[/tex]

Where,

[tex]B_A[/tex] is the area of the base of the pyramid and

h is the height or altitude of the pyramid

As shown in the diagram,

The pyramid has a square base whose side measures 6 inches and the altitude of the pyramid is 12 inches

Thus,

Area of the square base,

[tex]B_A =a^{2}[/tex]

⇒ [tex]B_A=6^2[/tex]

⇒ [tex]B_A=36[/tex] sq. inches

Height of the pyramid h = 12 inches

On substituting the values in the formula,

[tex]V=\frac{1}{3}B_Ah[/tex]

⇒ [tex]\frac{1}{3}[/tex] × 36 × 12

~Shane

The value of y when x equals 0 in the equation -3x - 9y = 36 is -4.

To find the value of y when x equals 0 in the equation -3x - 9y = 36, we can simply substitute 0 for x and solve for y.

Substituting 0 for x, the equation becomes:

-3(0) - 9y = 36

This simplifies to:

-9y = 36

Dividing both sides of the equation by -9, we get:

y = 36 / -9

This gives us:

y = -4

The circle area can be defined as x2 + y2 < 3.46^2.

For point M, x2 + y2 = 13.

Since 3.46^2 is about 12, point M is outside the circle!

Answer:

outside the circle

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ← r is the radius = 3.46410161514, hence

x² + y² = 3.46410161514²

x² + y² = 12 ← equation of circle

To determine where a point (x, y) lies

• If x² + y² < r² then point is inside the circle

• If x² + y² = r² then point lies on the circle

• If x² + y² > r² then point lies outside the circle

For (- 3, 2)

(- 3)² + 2² = 9 + 4 = 13 > 12

Hence point (- 3, 2) lies outside the circle

The volume of the triangular pyramid is calculated using the formula V = 1/3 × base area × height. With a base area of 330 square yards and height of 18 yards, the volume is found to be 1,980 cubic yards. Therefore, the correct answer is C.

Explanation:

The volume of a triangular pyramid can be calculated using the formula V = 1/3 × base area × height. Given that the base area is 330 square yards and the height of the pyramid is 18 yards, we can calculate the volume by substituting these values into the formula: V = 1/3 × 330 × 18 = 1980 cubic yards. Therefore, the correct answer is C. 1,980 yd³.

The volume of the triangular pyramid is 1,980 cubic yards, making the correct answer option C.

To find the volume of the triangular pyramid, we first need to determine the area of the base triangle. Since the base has an area of 330 square yards, we can use the formula for the area of a triangle, which is 1/2 * base * height. Let's denote the base of the triangle as b and the height as h. We can rearrange the formula to solve for b:

[tex]\[ 330 = \frac{1}{2} \times b \times h \][/tex]

Given that the height of the pyramid is 18 yards, we can plug this value in and solve for the base:

[tex]\[ 330 = \frac{1}{2} \times b \times 18 \][/tex]

330 = 9b

[tex]\[ b = \frac{330}{9} \][/tex]

b = 36.67

Now, we have the base length of the triangle. Next, we can calculate the volume of the pyramid using the formula for the volume of a pyramid, which is [tex]\( \frac{1}{3} \times base\ area \times height \)[/tex]. Let's denote the volume as V:

[tex]\[ V = \frac{1}{3} \times 330 \times 18 \][/tex]

V = 1980

So, the volume of the pyramid is 1980 cubic yards. Therefore, the correct answer is option C: 1,980 yd.
