Answer: $ 149.95.

Step-by-step explanation:A product is marked down 15%; the sale price is $127.46. What was the original price? Substitute 127.46 for S.P and 15 for m in (1). So, the original price is $ 149.95.

The original price of the product will be $149.95.

The quantity of anything is stated as though it were a fraction of a hundred.

A product is marked down 15%.

The sale price is $127.46.

Then the original price of the product will be

Let x be the original price.

(1 – 0.15)x = $127.46

      0.85x = $127.46

              x = $149.95

Answer:

d = 404.8 feet

Step-by-step explanation:

We take our eyes off the road for about 4.6 seconds according to a recent study.

Speed, v = 60 mph

We need to find the distance travel by you with your eyes not on the road. Let it is d.

Speed, v = d/t

d = vt

We know that, 1 mile = 5280 feet

[tex]d=\dfrac{60\times 5280\ \text{feet}}{3600\ s}\times 4.6\ s\\\\=404.8\ \text{feet}[/tex]

Hence, the required distance is 404.8 feet.

Answer:

Yes, there is a proportional relationship. For every 6 pounds of apple sold, they make $13.50.

Answer: the answer to this is x=0.5

Step-by-step explanation:

In order to solve this you have to combine the multiplied terms into a single fraction so its going to look like this -   34x/5 + 9.3= -9.4+3.4(2-5x)

The reposition your terms and put together your multiplied terms into a fraction,Once you have that done distribute them

Subtract 9.3 on both sides.you may simplify and then multiply all the terms with the same value to get rid of the denominators from the fractions

also add 85x to both sides then finally divide both side by the same term which get you -59.5/119 and then simplify and you get -0.5

so x= -0.5

Answer:

x=-0.5

Step-by-step explanation:

step 1

6.8x+9.3=-9.4+3.4(2-5x)

6.8x+9.3=-9.4+(3.4)(2)+(3.4)(-5x) distribute

6.8x+9.3=-9.4+6.8+-17x

6.8x+9.3=(-17x)+(-9.4+6.8) combine like terms

6.8x+9.3=-17x+-2.6

6.8x+9.3=-17x-2.6

step 2

add 17x to both sides.

6.8x+9.3+17x=-17x2.6+17x

23.8x+9.3=-2.6

step 3

subtract 9.3 from both sides.

23.8x+9.3-9.3=-2.6-9.3

23.8x=-119

step 4

divide both sides by 23.8

23.8x/23.8= -11.9/23.8

The answer is =-0.5

The cost of the necklace before tax, for which Chris paid $9.18 including the sales tax of 8% is $8.5.

Percentage increase is the amount added to the initial value in the percentage part.

Chris paid $9.18 for a necklace. This amount includes a sales tax of 8%.

Let the cost of the necklace before tax is x dollars. Now, the 108% of the x is $9.18. Thus,

[tex]x\times\dfrac{100+8}{100}=9.18\\x=\dfrac{9.18\times100}{108}\\x=8.5[/tex]

Hence, the cost of the necklace before tax, for which Chris paid $9.18 including the sales tax of 8% is $8.5.

The simplified form of 3√(512) using radical is 48√(2).

To simplify √(512), find the prime factorization of 512.

Prime factorization of 512:

512 = [tex]2^9[/tex]

Now, rewrite the square root as follows:

√(512) = √[tex](2^9)[/tex]

Next, use the property of square roots that states √(a * b) = √(a) * √(b):

√[tex](2^9)[/tex] = √([tex]2^8 * 2)[/tex]

         = √[tex](2^8) * \sqrt(2)[/tex]

Since √[tex](2^8)[/tex] is equal to [tex]2^4[/tex] then

√(512) = [tex]2^4[/tex] * √(2)

Finally, simplify √(2) as it is not a perfect square:

√(512) = [tex]2^4[/tex]* √(2)

          = 16 * √(2)

So, the simplified form is 48√(2).

Answer:

Step-by-step explanation:

A. (5,-4)

The vertex of the graph of the function is (5,-4).

The answer is option A.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

To find the vertex of the function y = x² - 10x + 21,

We can use the formula:

x = -b/2a

where a is the coefficient of the x² term, b is the coefficient of the x term, and x is the x-coordinate of the vertex.

In this case,

a = 1 and b = -10, so:

x = -(-10)/(2 x 1) = 5

To find the y-coordinate of the vertex, we can substitute x = 5 into the function:

y = (5)² - 10(5) + 21 = -4

Therefore,

The vertex of the graph of the function is (5,-4).

Answer:

The equation of this parabola in standard form is (y - 2)² = -8(x - 6) ⇒ B

Step-by-step explanation:

Let us revise the standard form of the equation of a parabola

The standard form of the equation is (y - k)² = 4p(x - h), where

∵ The vertex of a parabola is (6, 2)

→ From the fact above

∴ h = 6 and k = 2

∵ The equation of its directrix is x = 8

→ From the fact above

∴ h - p = 8

→ Substitute the value of h to find p

∵ 6 - p = 8

→ Subtract 6 from both sides

∴ - p = 2

→ Multiply both sides by -1

∴ p = -2

→ Substitute the values of h, k, and p in the form above

∴ (y - 2)² = 4(-2)(x - 6)

∴ (y - 2)² = -8(x - 6)

∴ The equation of this parabola in standard form is (y - 2)² = -8(x - 6)

Finding the Common Ratio:

We know that the formula for the common ratio of a GP is:

r = aₙ / (aₙ₋₁)        (Where n is any integer)

replacing the values, taking n=2

r = -21 / 7

r = -3

Solving for the 15th Term:

We know that the Formula for the nth term of a GP:

G(n) = a * r ⁿ⁻¹     (where a is the first term and r is the common ratio)

replacing the values (taking n = 15 since we need the 15th term)

G(15) = 7 * (-3)¹⁴

G(15) = 33480783

Hence, the 15th term of the given GP is 33480783

Step-by-step explanation:
