It is possible that the ball may reach a height of 5 meters in accordance with the quadratic formula.

The height of the ball as a function of time is represented by a quadratic equation, in which we must determine if the ball may reach a height of 5 meters. First, substitute the height in the quadratic equation:

- 5 · t² + 9 · t + 2 = 5

5 · t² - 9 · t + 3 = 0

Second, use the quadratic formula to determine the roots of the resulting quadratic equation:

t = - (- 9) / (2 · 5) ± [1 / (2 · 5)] · √[(- 9)² - 4 · 5 · 3]

t = 9 / 10 ± (1 / 10) · √(81 - 60)

t = 9 / 10 ± √21 / 10

t = (9 ± √21) / 10

Since all roots of the quadratic equations are real, then the ball can reach a height of 5 meters above the ground.

Since in the question we reject the alternative hypothesis hence type II error occurs.

What is Type I error?

When the null hypothesis is true but rejected in hypothesis testing, type 1 errors often confused with false positives occur. A general assertion or default attitude that there is no connection between two measurable phenomena is known as the null hypothesis.

What is Type II error?

Type II errors take place when you fail to reject the null hypothesis even though it is untrue.

The average number of insect parts per 100 gm in this problem is 75. This number cannot be demonstrated by the test to be larger than 75. This indicates that the test is producing a "false negative" since it is not detecting these insect parts.

Hence, this is a Type II error.

The length of x is 4.1.

Given:

Base = 9 + 4.5 = 13.5

From figure:

= [tex]\sqrt{9^{2}+5^{2} }[/tex]

= [tex]\sqrt{81+25}[/tex]

= [tex]\sqrt{96}[/tex]

= 9.797

4.5 opposite is equal to 4.5.

5 opposite equal to 5 and remaining to x - 5.

According to pythagorean theorem:

= [tex]\sqrt{4.5^{2}+(x-5)^{2} }[/tex]

[tex]13.5^{2} +x^{2} =(\sqrt{96}+\sqrt{4.5^{2} +(x-5)^{2} })^{2}[/tex]

[tex]\sqrt{13.5^{2} +x^{2} }[/tex] - [tex]\sqrt{96} = \sqrt{20.25+x^{2} +25 -10x}[/tex]

squaring on both sides

182.25 + [tex]x^{2}[/tex] - 96 = [tex]x^{2}[/tex] - 10x + 45.25

10x = 45.25 + 96 - 182.25

10x = 41

x = 4.1.

The statement that best compares the graph of G(x) with the graph of F(x) is the graph of G(x) is the graph of F(x) compressed vertically, flipped over the x-axis, and shifted 7 units to the left.

According to the question,

We have the following information:

F(x) = x² and G(x) = -1/4 (x+7)²

Now, the graph of G(x) will be the graph of F(x) but there will be certain changes in the graph according to its function.

Now, in this function, 7 is added to x then it means that it will shift 7 units to left.

There is a negative sign before the function which says that is flipped over the x-axis.

Now, the factor 1/4 in the multiplication says that it has been compressed.

Hence, the correct option is D.

Answer:

a is right (prime number is always a even number)

Answer:

A.

a prime number may be an even or an odd number

Answer:

angle a = 74 degrees

angle b = 106 degrees

angle c = 106 degrees

angle d = 65 degrees

angle e = 65 degrees

Step-by-step explanation:

Angle a:

the Alternate Interior Angles Theorem makes angle a equal to 74 degrees

Angle b:

First find angle c, and angle b is equal to angle c because angle b and c are Corresponding angles

Angle c:

angle c = 180 degrees - 74 degrees

angle c = 106 degrees

Angle d:

angle d corresponds with 65 degrees, therefore the are the same.

Angle e:

angle d and e are opposite angles, therefore they are the same.

Circumference = pi x d

Circumference = 3.14 x 24 =  75.36

1353 numbers of minutes he has used his phone in a month.

What do you mean by algebraic expression?

In mathematics, an algebraic expression is an expression composed of integer constants, variables, and algebraic operations (addition, subtraction, multiplication, division, and exponentiation by exponents that are rational numbers).

Algebraic equations are equations that contain only algebraic expressions.

Algebraic expression is the idea of ​​using letters or alphabets to represent numbers without specifying the actual value. Algebra Basics taught us how to use letters like x, y, and z to represent unknown values. These characters are called variables here.

It is given that Chang pays a monthly fee of $27, and he pays an additional $0.07 per minute of use.

Let m be the additional minutes

Then charge for additional minutes is $0.07m

Now , it is also given that least he has been charged in a month is

$121.71.

⇒ 0.07m + 27 = 121.71

⇒ 0.07m = 121.71 - 27

⇒ 0.07m = 94.71

⇒ m = 94.71/0.07 = 1353

Therefore, 1353 numbers of minutes he has used his phone in a month.

The perimeter of the smaller square would be = 12feet. That is option B.

Perimeter can be defined as the summation of all the sides and edges of an object.

Scale factor is also defined as the ratio of difference between an original object and a newly formed object.

A square has four sides and it's perimeter = 24 ft

This means that the sides of the square= 24/4 = 6ft.

If the original (smaller square) dialted by a factor of 1/2 to have 6 ft as its sides, it means that it's original side of the small square is 3ft.

This is because to form the bigger square, 1/2 × 6 = 3ft.

Therefore, the perimeter of small square = 3+3+3+3 = 12ft.

Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categorize ratios.

Part to whole ratio is one, and part to part ratio is the other. The part-to-part ratio shows the relationship between two separate entities or groupings.
