Answer:

-1040 feet

Step-by-step explanation:

Since the altitude decreases at 40 feet per second, we can find the change in altitude by multiplying -40 by the number of seconds:

So, multiply -40 by 26:

-40(26)

= -1040

So, the change in altitude will be -1040 feet

Natural numbers are: 1, 2, 3, ....

Integer numbers are: ...., -2, -1, 0, 1, 2, ... (so it includes positive and negative natural number, and 0 )

Rational numbers are numbers which can be written in the form of a/b  

where a and b are integers.

Irrational numbers are those real numbers which are not rational numbers.

Here, Know that all natural numbers are integers, all integers are rational numbers. That means, natural numbers are not irrational.

A composite number is a number divisible by another number than 1 and the number itself.

To find example, a sum of two composite numbers, which is not a composite number, is needed.

Step-by-step explanation:

Given equation

The roots are

Substitute values into equation

This is matching the option B

Answer:

\(x=\dfrac{3 \pm \sqrt{29}}{2}\)

Step-by-step explanation:

Given equation:

\(x^2-3x-5=0\)

To find the exact solutions of the given equation, use the quadratic formula or complete the square.

Method 1:  Quadratic Formula

\(x=\dfrac{-b \pm \sqrt{b^2-4ac} }{2a}\quad\textsf{when }\:ax^2+bx+c=0\)

Therefore:

\(a=1, \quad b=-3, \quad c=-5\)

Substituting these values into the formula:

\(\implies x=\dfrac{-(-3) \pm \sqrt{(-3)^2-4(1)(-5)} }{2(1)}\)

\(\implies x=\dfrac{3 \pm \sqrt{29}}{2}\)

Method 2:  Completing the square

Move the constant to the right side by adding 5 to both sides:

\(\implies x^2-3x-5+5=0+5\)

\(\implies x^2-3x=5\)

Add the square of half the coefficient of x to both sides:

\(\implies x^2-3x+\left(\dfrac{-3}{2}\right)^2=5+\left(\dfrac{-3}{2}\right)^2\)

\(\implies x^2-3x+\dfrac{9}{4}=\dfrac{29}{4}\)

Factor the perfect trinomial on the left side:

\(\implies \left(x-\dfrac{3}{2}\right)^2=\dfrac{29}{4}\)

Square root both sides:

\(\implies \sqrt{\left(x-\dfrac{3}{2}\right)^2}=\sqrt{\dfrac{29}{4}}\)

\(\implies x-\dfrac{3}{2}=\pm\dfrac{\sqrt{29}}{2}\)

Add 3/2 to both sides:

\(\implies x-\dfrac{3}{2}+\dfrac{3}{2}=\pm\dfrac{\sqrt{29}}{2}+\dfrac{3}{2}\)

\(\implies x=\dfrac{3 \pm \sqrt{29}}{2}\)

Answer:

The selling price of the diamond necklace at Shamin Jewelers after 10% discount is:

$442 * 0.9 = $397.80

The selling price of the same necklace at the competitor's store after 34% and 14% discount is:

$527 * 0.66 * 0.86 = $247.08

So, Shamin Jewelers needs to offer an additional discount to meet the competitor's price:

$397.80 - $247.08 = $150.72

To calculate the additional rate of discount, we divide the difference by the original selling price at Shamin Jewelers and multiply by 100:

($150.72 / $442) * 100 = 34.11%

Therefore, Shamin Jewelers must offer an additional 34.11% discount to meet the competitor's price.

Step-by-step explanation:

Step-by-step explanation:

that kind of wording is always misleading.

please give my regards and comments to your teacher.

a square root has ALWAYS 2 solutions : a positive AND a negative one.

in that sense the negative solution to a square root is NOT an extraneous solution.

only any value of x < -10 (to make the argument of the square root negative) as solution would be extraneous.

so, if your teacher wants to say that only the positive solutions of a square root are allowed, it has to be said as an extra definition or by applying the "+" sign to the square root.

so,

x + 4 = sqrt(x + 10)

since the 2 solutions are already given to us, we only need to use them in the equation and see what happens.

x = -1

-1 + 4 = sqrt(-1 + 10)

3 = sqrt(9) = 3 (actually, it is ±3)

so, x = -1 is a real solution.

x = -6

-6 + 4 = sqrt(-6 + 10)

-2 = sqrt(4) = 2 (actually, it is ±2)

so, based on your teacher's expectation of only positive results of the square root (even though it was not stated),

x = -6 is an extraneous solution.

therefore, the third answer (c) is the "correct" answer.

but actually, formally, the second answer (b) is the truly correct answer.

The fraction of whole pizza has both pepperoni and green peppers exists 1/2.

A number is stated mathematically as a quotient, where the numerator and denominator are divided. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction exists less than the denominator.

Given that:

3/4 of the pizza contains pepperoni

2/3 of the pizza with pepperoni contains green pepper ;

The fraction of the whole pizza that contains both pepperoni and green pepper;

The fraction with pepperoni = 3/4

Fraction of whole with green pepper and pepperoni: 2/3 of 3/4

simplifying the above equation, we get

= 2/3 × 3/4

= (2 × 3) / (3 × 4)

= 6/12 = 1/2

The height of the roof is 21 inches.

Any triangle with any two sides that have the same length is known as an isosceles triangle. An isosceles triangle has two equal-sized angles that are opposite from one other and have equal sides. In other terms, an isosceles triangle is a triangle with two congurrent sides.  

Here we have,

Tony is building a doghouse, and the front view of the roof is an isosceles triangle.  

As we consider, the front view as an isosceles triangle

Side of the triangle = 29 inches

Base of the triangle = 40 inches

When we draw a line along the height of the triangle, it will divide the base equally and forms two right-angle triangles.

Let 'x' be the height of the triangle  

If we apply the Pythagorean theorem,

=> 29² = 20² + x²  

=> 841 = 400 + x²

=> x² = 441

=> x² = (21)²

Answer:

The cost per ounce of the small cup is $0.269

Step-by-step explanation:

To find the cost per ounce, we can divide the cost of the cup by the number of ounces it holds.

Cost per ounce = Cost of the cup ÷ Number of ounces in the cup

Cost of the cup = $2.69

Number of ounces in the cup = 10 oz

So,

Cost per ounce = $2.69 ÷ 10 oz

Cost per ounce = $0.269 per oz (rounded to the nearest thousandth)

Therefore, the cost per ounce of the small cup is $0.269.

In the proportion (5x + 1):3 = (2x + 2):7, the value of x is -1/29.

In the proportion (6x):(4x) = 7, there is no value of x that satisfies the proportion.

To find the value of x in the given proportions, let's solve them one by one:

(5x + 1) : 3 = (2x + 2) : 7

To solve this proportion, we can cross-multiply:

7(5x + 1) = 3(2x + 2)

35x + 7 = 6x + 6

Subtracting 6x from both sides and subtracting 7 from both sides:

35x - 6x = 6 - 7

29x = -1

Dividing both sides by 29:

x = -1/29

Therefore, the value of x in the first proportion is -1/29.

(6x) : (4x) = 7

To solve this proportion, we can simplify the left side:

6x / 4x = 7

Dividing both sides by 2x:

3/2 = 7

This equation is not true, as 3/2 is not equal to 7.

Therefore, there is no value of x that satisfies the second proportion.

In summary, the value of x in the proportion (5x + 1) : 3 = (2x + 2) : 7 is -1/29, and there is no value of x that satisfies the proportion (6x) : (4x) = 7.
