Answers

"8 in., 15 in., 17 in." is a right triangle and "4 in., 15 in., 17 in." is not a right triangle. Hope this helps!

Answer:

8 in 15 in 17 in.--- form a right angled triangle.

4 in 15 in 17 in.---- do not form a right angled triangle.

Step-by-step explanation:

We know that according to the PYTHAGOREAN THEOREM of right triangles we have:

                             [tex]c^2=a^2+b^2[/tex]

where c is the hypotenuse or the largest side of a triangle and a and b are other two legs of a right triangle,.

1)

8 in 15 in 17 in.

[tex]17^2=15^2+8^2\\\\289=225+64\\\\289=289[/tex]

Hence, the given measure of sides form a side of a right angled triangle.

2)

4 in 15 in 17 in.

Since,

[tex]17^2\neq 15^2+4^2[/tex]

Hence, the given measure of sides do not form a side of a right angled triangle.

What is Addition?

Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.

The process of doing addition is also called as finding the sum.

Let x and y be the two numbers.

We have sum of them is -1/3

x + y = -1/3  [Equation 1]

The difference of two numbers is 18.

x - y = 18   [Equation 2]

Adding equations 1 and 2,

x + y + x - y = -1/3 + 18

2x = 18 - [tex]\frac{1}{3}[/tex]

2x = 53/3

x = 53/6

Substituting the value in equation 1,

53/6 + y = -1/3

y = -1/3 - 53/6

  = -55/6

Hence the numbers are 53/6 and -55/6.

Nadiya determines that there are no fractions equivalent to 2/10 with a denominator greater than 10, but less than 20, that have a whole number numerator and denominator. Is Nadiya correct?

Yes, Nadiya is correct. By multiplying the numerator and denominator by 2, the first fraction equivalent to 2/10 is 4/20.

Yes, Nadiya is correct. By multiplying the whole fraction by any whole number, each equivalent fraction will continue to have a denominator of 10.

No, Nadiya is incorrect. She could multiply both the numerator and denominator of the unit fraction equivalent to 2/10 by 3 and arrive at the equivalent fraction 3/15.

No, Nadiya is incorrect. She could add any number between 1 and 8 to the numerator and denominator and arrive at an equivalent fraction with a denominator greater than 10 but less than 20.

Answers

Final answer:

No, Nadiya is incorrect. There is a fraction equivalent to 2/10 with a denominator greater than 10 but less than 20, which is 3/15.

Explanation:

No, Nadiya is incorrect. She could multiply both the numerator and denominator of the unit fraction equivalent to 2/10 by 3 and arrive at the equivalent fraction 3/15.

When multiplying a fraction by a whole number, both the numerator and the denominator are multiplied by that number. By multiplying 2/10 by 3, we get (2 * 3)/(10 * 3) = 6/30, which can be simplified to 3/15.

Therefore, there is a fraction equivalent to 2/10 with a denominator greater than 10 but less than 20, and it is 3/15.

We need to find where our first derivative is positive.
The first derivative is parabola that has positive coefficient a. Parabolas with positive coefficient a ("happy" parabolas or concave) are negative between zeros and positive everywhere else. So our function is increasing when x<-2 and x>2.
In order to determine where the function is concave up  or down, we have to find the second derivative.

John bought a used truck for $4,500. He made an agreement with the dealer to put $1,500 down and make payments of $350 for the next 10 months. The extra cost paid by taking this deal is equivalent to what actual yearly rate of interest? A. 33% B. 36% C. 3.6% D. 63%

Answers

Answer: option A. 33%

Explanation:

1) Purchase price: $4500

2) Payments:

down: $1500
monthly: $350 * 10 = 3500

Total payments = $1500 + $3500 = $5000

3) Difference: $5000 - $3500 = $1500 = extra cost

4) Percent extra cost = (difference / purchase price) * 100 = ($1500/$4500)*100 = 33.3%

Answer-

The extra cost paid by taking this deal is equivalent to actual yearly rate of interest 36%

Solution-

Price of truck = $4500

John made a down payment of $1500, so the present value of annuity will be,

[tex]4500-1500=\$3000[/tex]

We know that,

[tex]\text{PV of annuity}=P[\frac{1-(1+r)^{-n}}{r}][/tex]

[tex]PV\ of\ annuity=3000,\\\\P=350,\\\\r = x%\ monthly\\\\n=10\ months[/tex]

Putting  the values,

[tex]\Rightarrow 3000=350[\dfrac{1-(1+x)^{-10}}{x}][/tex]

[tex]\Rightarrow \dfrac{3000}{350}=[\dfrac{1-(1+x)^{-10}}{x}][/tex]

[tex]\Rightarrow \dfrac{60}{7}x=1-(1+x)^{-10}[/tex]

[tex]\Rightarrow (1+x)^{-10}+\frac{60}{7}x-1=0[/tex]

Using calculator we get,

[tex]\Rightarrow x=0.0291=2.91\% \approx 3\%[/tex]

Therefore, annual interest will be,

[tex]=12\times x=12 \times 3=36\%[/tex]

Find the dimensions of the rectangular box with largest volume if the total surface area is given as 16 cm2. (let x, y, and z be the dimensions of the rectangular box.) (x, y, z) =

Answers

The largest volume cuboid for a given surface area is a cube. The total surface area of a cube is 6 times the square of the length of one edge, so your dimensions are

&nbsp; x = y = z = √(16/6) cm = (2/3)√6 cm, about 1.633 cm

Final answer:

Finding the exact dimensions of a rectangular box with the largest volume from a given surface area of 16 cm2 requires additional constraints. For illustrative purposes, in the case of a cube with equal sides, the side length can be found using the formula for surface area, showing how such a problem might be approached.

Explanation:

To find the dimensions of a rectangular box with the largest volume given a total surface area of 16 cm2, we can use the method of Lagrange multipliers or understand the principle that for a given surface area, the box which is closest to a cube will have the largest volume. However, without additional constraints, like a relation between the dimensions (x, y, z), solving for specific x, y, z values directly from just the surface area constraint alone leads to an infinite number of solutions. For simplicity, we'll consider a problem where symmetry is involved, as in the case of a cube, to illustrate how one might approach it.

Surface area of a rectangular box is given by 2(xy + xz + yz) = 16 cm2. To simplify and directly answer based on the data given would require additional constraints, such as assuming all sides are equal. For a cube, with all sides equal (let’s call each side 'a'), the surface area would be 6a^2. Solving 6a^2 = 16 gives a = sqrt(16/6) ≈ 1.633. This illustrates a scenario under specific conditions but doesn't directly solve the original question without additional constraints.

Answer is C

The amount of three-dimensional space enclosed by a closed surface is expressed as a scalar quantity is called volume. The volume of the given figure is 233 in³.

What is Volume?

The amount of three-dimensional space enclosed by a closed surface is expressed as a scalar quantity is called volume.

The given figure can be divided into two parts. The first figure 'A' is a cuboid, while the second figure 'B' is a cube. As shown below.

Now, the volume of the figure can be calculated by adding the volume of the cuboid A and the volume of the cube B.

The volume of Cuboid A can be written as,

[tex]\rm \text{Volume of cuboid} = Length \times Breadth \times Height[/tex]

                            [tex]= 12 \times 3 \times 3\\\\= 108\rm\ in^3[/tex]

The volume of Cube B can be written as,

[tex]\rm \text{Volume of Cube} = (Side)^3[/tex]

                        [tex]= 5^3\\\\= 125\rm\ in^3[/tex]

Further, the volume of the figure can be written as,

The volume of the figure = Volume of the cuboid + Volume of the Cube

                                          = 108 + 125 = 233 in³

Hence, the volume of the given figure is 233 in³.

[tex]\sf x\times x=x^2[/tex]
[tex]\sf x\times 3=3x[/tex]
[tex]\sf 4\times x=4x[/tex]

Combine like terms(3x + 4x = 7x):

[tex]\sf A=\boxed{\sf x^2+7x+12}[/tex]
Final answer:

To find the area of a parallelogram with base length x+4 and height x+3, multiply these two values to yield an area represented by the quadratic equation x²+7x+12.

Explanation:

The area of a parallelogram is calculated by multiplying the base length by the height of the parallelogram. For a parallelogram with a base length of x+4 and a height of x+3, the area can be found by the formula Base x Height = Area of parallelogram.

The calculations follow these steps:

Identify the base (x+4) and the height (x+3).Multiply the base and height: (x+4)(x+3).Continuing with algebra, expand the expression: x²+3x+4x+12.Combine like terms to get the final area: x²+7x+12.

Therefore, the area of the parallelogram is represented by the equation x²+7x+12, given the dimensions provided.
