Answer:

Option (a) is correct.

For given values a = 1 , b = -3 , c = -5 the quadratic equation is  

Step-by-step explanation:

Given : a = 1 , b = -3 , c = -5

We have to write the quadratic equation having a = 1 , b = -3 , c = -5 and choose the correct option.

The standard form of quadratic equation is  , where a, b, c are constant integers.

Given : a = 1 , b = -3 , c = -5

Then Substitute, we get,

Thus, the obtained quadratic equation is same as option (a)

Thus, For given values a = 1 , b = -3 , c = -5 the quadratic equation is

The equation for which a-value 1, ab-value -3 and ac-value -5 is 0=-3x-5+x².

Quadratics can be defined as a polynomial equation of a second degree, which implies that it comprises a minimum of one term that is squared. It is also called quadratic equations.

Here, a-value = 1,

        ab-value =  -3

        ac-value = -5

a = 1, b = -3, and c = -5

General Equation,

ax² + bx + c = 0

1x² + (-3)x + (-5) = 0

x² -3x -5 = 0

Thus, the equation for which a-value 1, ab-value -3 and ac-value -5 is 0= -3x -5 + x².

Answer:

\( s = \sqrt{30} - 2\sqrt{5} m \)

Step-by-step explanation:

Given:

Formula for side length of cube, \( s = \sqrt{\frac{SA}{6} \)

Where, S.A = surface area of a cube, and s = side length.

Required:

Difference in side length between a cube with S.A of 180 m² and a cube with S.A of 120 m²

Solution:

Difference = (side length of cube with 180 m² S.A) - (side length of cube with 120 m² S.A)

\(s = (\sqrt{\frac{180}{6}}) - (\sqrt{\frac{120}{6}})\)

\( s = (\sqrt{30}) - (\sqrt{20}) \)

\( s = \sqrt{30} - \sqrt{4*5} \)

\( s = \sqrt{30} - 2\sqrt{5} m \)

Based on the task content given; the solution to the equation for x 3 1/2(2 1/5x - 4 2/3) - 5 5/6 = 0 is 2 203/231

3 1/2(2 1/5x - 4 2/3) - 5 5/6 = 0

(3 1/2 × 2 1/5x) - (3 1/2 × 4 2/3) - 5 5/6 = 0

(7/2 × 11/5x) - (7/2 × 14/3) - 35/6 = 0

77/10x - 98/6 - 35/6 = 0

77/10x = 98/6 + 35/6

77/10x = 98+35 / 6

77/10x = 133/6

x = 133/6 ÷ 77/10

Answer:

4%

Step-by-step explanation:

Gain percentage = 1030/25750 x 100 = 4%

Answer:

$1,030, 4%

Step-by-step explanation:

Aman spent $25,750 on a computer and accessory packs (totally worth it). He sold it for $26,780. So let's say Aman is at 0 before he bought this. He spent $25,750, so we subtract that from 0 to get -25,750. Then he sells it all for $26,780 (again totally worth it for the person buying). So we add 26,780 to the total.

-25,750 + 26,780 = 1,030

So Aman made a profit of $1,030 (now he can buy a REASONABLY priced MacBook Air or something)

So to find the percentage that he gained, we divide 1,030 by his original spending price, namely 25,750

1,030/25,750 = 0.04

Convert that to percentage form, you get 4%

The value of the height of the prism is 8.68 inches

The surface area is the sum of the area of the faces.

The formula for calculating the surface area of the pyramid is;

TSA  = \(a^2+2a\sqrt{\frac{a^2}{4} + h^2}\)

where

a is the side length. = 7in

h is the height

Substitute

\(189=7^2+2(7)\sqrt{\frac{7^2}{2} + h^2} \\189=49+14\sqrt{\frac{49}{2} + h^2}\\140=14\sqrt{\frac{49}{2} + h^2}\\10=\sqrt{\frac{49}{2} + h^2}\\\)

Square both sides to have

Clara can reach a height of 2.57 meters when she jumps.

Given information:

The ceiling in Clara’s basement is 2.75 meters high.

When Clara jumps she is 18 centimeters short of being able to touch the ceiling.

We can start by converting the height of the ceiling and Clara's jump to the same units, either meters or centimeters. Let's convert Clara's jump to meters:

18 centimeters = 0.18 meters

Now we can subtract Clara's jump from the height of the ceiling to find how high she can reach:

Answer:

Therefore, the tent company needs about 10752 square inches of fabric to make the tent.

Step-by-step explanation:

To find the surface area of the tent, we need to find the area of each face and add them together. Looking at the net provided, we see that the tent has 5 faces: two congruent triangles (ABD and CDE), two rectangles (ABCF and DEGH), and a parallelogram (BCDE).

Let's start with the triangles. To find the area of triangle ABD, we can use the formula for the area of a triangle:

Area of ABD = (1/2) * base * height

The base is the side AB, which has a length of c = 42 inches, and the height is a, which has length of 67 inches. So we have:

Area of ABD = (1/2) * 42 * 67 = 1407 square inches

Since triangle ABD is congruent to triangle CDE, they have the same area. Therefore, the total area contributed by the two triangles is:

2 * Area of ABD = 2 * 1407 = 2814 square inches

Next, let's find the area of the two rectangles. The rectangle ABCF has length b = 68 inches and height a = 67 inches, so its area is:

Area of ABCF = b * a = 68 * 67 = 4556 square inches

The rectangle DEGH has length d = 64 inches and height a = 67 inches, so its area is:

Area of DEGH = d * a = 64 * 67 = 4288 square inches

Finally, let's find the area of the parallelogram BCDE. To do this, we need to find the height of the parallelogram, which is the perpendicular distance between the base BC and the line DE. We can use the Pythagorean theorem to find this height:

h = sqrt(d^2 - b^2) = sqrt(64^2 - 68^2) ≈ 38.48 inches

Therefore, the area of the parallelogram is:

Area of BCDE = base * height = c * h = 42 * 38.48 ≈ 1613.76 square inches

Adding up the areas of all 5 faces, we get the total surface area of the tent:

Total surface area = 2 * Area of ABD + Area of ABCF + Area of DEGH + Area of BCDE

= 2 * 1407 + 4556 + 4288 + 1613.76 ≈ 10752 square inches

Therefore, the tent company needs about 10752 square inches of fabric to make the tent.

Answer:

Take note that the quotient's decimal point is precisely above the dividend's decimal point. To divide a decimal by a whole number, move the decimal point in the quotient above the decimal point in the dividend and divide as usual.

Step-by-step explanation:

It all depends on the divisor.

You need to make sure the decimal of the divisor is at the end.

For example, 2.09 divided by 0.19

You need to move the decimal point of 0.19 two times to the right so the decimal point is at the end.

If the divisor is a whole number, the decimal would stay at the same position.

For example, 25.5 divided by 5, the decimal would stay since 5's decimal point is already at the end (5.)

By using the figure below, the value of line segment PT is equal to 54 units.

In Mathematics, the midpoint of a line segment with two endpoints can be calculated by adding each point on a line segment together and then divide by two (2).

Since T is the midpoint of PQ, we have the following:

Line segment PT = Line segment TQ

7x + 5 = 9x - 9

9x - 7x = 9 + 5

2x = 14

Step-by-step explanation:

\(5. {x}^{3} - xy + {y}^{2} = 4\)

\( \frac{dy}{dx} ( {x}^{3} - xy + {y}^{2} ) = \frac{dy}{dx} (4)\)

\(3 {x}^{2} - x(1) \frac{dy}{dx} + 1(y) + 2y \frac{dy}{dx} \)

Combine the dy/dx.

\( \frac{dy}{dx} ( - x + 2y) + y + 3 {x}^{2} \)

\( \frac{dy}{dx} ( - x + 2y) = - 3 {x}^{2} - y\)

\( \frac{dy}{dx} = \frac{ - 3 {x}^{2} - y}{ - x + 2y} \)

\( \frac{3 {x}^{2} + y }{x - 2y} \)

Answer:

\(\frac{dy}{dx}\) = \(\frac{y-3x^2}{2y-x}\)

Step-by-step explanation:

using the product rule to differentiate - xy then

3x² - (x\(\frac{dy}{dx}\) + y(1) ) + 2y\(\frac{dy}{dx}\) = 0

3x² - x\(\frac{dy}{dx}\) - y + 2y\(\frac{dy}{dx}\) = 0

3x² + \(\frac{dy}{dx}\) (2y - x) - y = 0 (subtract 3x² - y from both sides )

\(\frac{dy}{dx}\) (2y - x) = y - 3x² ← divide both sides by (2y - x)

\(\frac{dy}{dx}\) = \(\frac{y-3x^2}{2y-x}\)
