The measure of the third side of the triangle will fall between 5 and 29.

Triangle Inequality Theorem is that for two sides of a triangle, the third side cannot be equal to or greater than the third side's length.

From the Triangle Inequality Theorem,

The sum of the lengths of any two sides of a triangle must be greater than the third side, then the third side of this triangle must be strictly less than 29.

But we can't make the length of the third side too small, either.

If x is the length of the third side, then x + 12 > 17, which means that x > 5

Therefore, the length of the third side must fall between 5 and 29.

Hence, the measure of the third side of the triangle will fall between 5 and 29.

Answer:

The highest height the ball achieves is 4.5125 meters.

Step-by-step explanation:

Vertex of a quadratic function:

Suppose we have a quadratic function in the following format:

[tex]f(x) = ax^{2} + bx + c[/tex]

It's vertex is the point [tex](x_{v}, y_{v})[/tex]

In which

[tex]x_{v} = -\frac{b}{2a}[/tex]

[tex]y_{v} = -\frac{\Delta}{4a}[/tex]

Where

[tex]\Delta = b^2-4ac[/tex]

If a<0, the vertex is a maximum point, that is, the maximum value happens at [tex]x_{v}[/tex], and it's value is [tex]y_{v}[/tex].

In this question:

Quadratic function [tex]y = -0.2x^2 + 1.9x[/tex], which has [tex]a = -0.2, b = 1.9[/tex].

The maximum height of the ball is [tex]y_{v}[/tex].

Then

[tex]\Delta = b^2-4ac = (1.9)^2 - 4*(-0.2)(0) = 3.61[/tex]

[tex]y_{v} = -\frac{3.61}{4(-0.2)} = 4.5125[/tex]

The highest height the ball achieves is 4.5125 meters.

Given:

The sides of a right triangle are 2 cm, 3 cm, and 3.6 cm.

To find:

The area of the right triangle.

Solution:

Area of a triangle is:

[tex]Area=\dfrac{1}{2}\times base\times height[/tex]

In the given triangle 3.6 cm is the largest side, it means 3.6 cm is the length of the hypotenuse. So, 2 cm and 3 cm and the base and height of the triangle.

Now, the area of the given triangle is:

[tex]Area=\dfrac{1}{2}\times 2\times 3[/tex]

[tex]Area=3[/tex]

Therefore, the area of the given triangle is 3 square cm.

Answer:

3 centimeters^2

Answer:

x = 46

Step-by-step explanation:

Hello there!

The following angles are corresponding angles

One of the properties of corresponding anlges is that they are congruent

That being said we can use this equation to solve for x

2x + 4 = 4x - 88

step 1 subtract 2x from each side

2x -2x cancels out

4x - 2x = 2x

now we have

4 = 2x - 88

step 2 add 88 to each side

-88 + 88 cancels out

4 + 88 = 92

now we have 92 = 2x

step 3 divide each side by 2

92 / 2 = 46

2x/2= x

we're left with x = 46

The mass of each bag of flour is 2 kg.

In physics, mass is a quantitative measure of inertia, which is a fundamental property of all matter. In the International System of Units, a kilogram is a unit of mass (SI).

Given that the mass of each bag of rice is 1.2 kg. We can see that there are 5 and 3 bags containing rice and flour respectively. First, we have to calculate the total weight of the right side of the weight machine. Then we equate it with the total weight of the left side of the weight machine.

Let, the mass of each bag of flour be y kg.

Now,

Weight of the right side = Weight of the left side

i.e. number of rice bags × mass of rice bags = no. of flour bags × mass of flour bags

i.e. 5 × 1.2 = 3 × y

i.e. 3y = 6.0

i.e. y =6/3=2

So, the mass of each bag of flour is 2 kg.

Answer:

Number of year, when final value is $61,412.50 = 3 year

Number of year, when final value is $20,000 = 10 year (Approx.)

Step-by-step explanation:

Given:

Depreciation model

y = 100,000[0.85]ˣ

Where x = Number of year

Find:

Number of year, when final value is $61,412.50

Number of year, when final value is $20,000

Computation:

Depreciation model

y = 100,000[0.85]ˣ

61,412.50 = 100,000[0.85]ˣ

0.614125 = [0.85]ˣ

x = 3

Number of year, when final value is $61,412.50 = 3 year

Depreciation model

y = 100,000[0.85]ˣ

20,000 = 100,000[0.85]ˣ

0.2 = [0.85]ˣ

x = 10 (Approx.)

Number of year, when final value is $20,000 = 10 year (Approx.)
