The value of t for which the rockets height is 25 meters is 40.7 seconds

From the information, the ball is thrown with an initial height of 4 feet with an initial velocity of 36 ft/s. h= 4 + 36t - 16t².

Therefore, the values of t for which the rockets height is 25 meters will be:

h= 4 + 36t - 16t².

where h = 25

25 = 4 + 36t - 16t².

Collect like terms

25 - 4 - 36t + 16t² = 0

16t² - 36t -21 = 0

Using almighty formula

t = 40.7 seconds.

Therefore, the value of t for which the rockets height is 25 meters is 40.7 seconds

Step-by-step explanation:

The values of the expression are 34, 2,18 and 11 respectively

The meaning of the expression PEMDAS is as shown below;

P is the parenthesis

E is the expoenent

M is the multiplication

D is the division

A is the addition

S is the subtraction

Simplifying the given expression

2 + 32

18 – 17 + 1

24 ÷ 4 × 3

21 – 5 × 2

2 + 32 =2 + (30 + 2)

2 + 32 = 2 + 30 + 2

2 + 32 = 34

For the expression 18 - 17 + 1

18 - 17 + 1 = 1 + 1

18 - 17 + 1 = 2

For the expression 24 ÷ 4 × 3 (Division first then multiplication)

24 ÷ 4 × 3 = (24 ÷ 4) × 3

24 ÷ 4 × 3 = 6 × 3

24 ÷ 4 × 3 = 18

For the expression 21 – 5 × 2

21 – (5 × 2)= 21 - 10

21 – 5 × 2 = 11

Hence the values of the expression are 34, 2,18 and 11 respectively

The account balance at the end of the month is $283.61

What distinguishes withdrawals from deposits?

The deposits into the bank would increase the balance, hence, they have positive sign whereas the withdrawals would decrease the balance since their sign is negative, in other words, we can determine the account balance at the end of the month by adding deposits to beginning balance and deducting all withdrawals

ending balance=beginning balance+ deposits-withdrawals

beginning balance=$80.83

total deposits=$107.51+$102.07+$110.57

total deposits=$320.15

total withdrawals=-$99.71-$17.66

There is 9,000 Joule energy present in the bulb

Gravitational Potential Energy

The energy that an object store due to its height in a gravitational field is known as gravitational potential energy.

It can be calculated by using  the equation below

U=m.g.h

Where:

m = mass of the object

h  = height

g  = acceleration due to gravity, or

Since the weight of an object of mass m can be calculated as:

W = m.g

The gravitational potential energy is:

U = W.h

The bell of weight W=180 N at the top of a tower is h=50 m high. Thus its energy is:

U = 180 N * 50 m

U = 9000 Joule

Hence, The bell has 9,000 Joule energy.

The required value of the missing side is 66 miles and 20 miles.

It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides.

This theorem can be written as an equation relating the lengths of the legs a, b and the hypotenuse c, often called the Pythagorean equation:

[tex]{\displaystyle a^{2}+b^{2}=c^{2}[/tex]

Now it is given that,

Length of Hypotenuse = 130 miles

Let length of one side = x

Since the difference between the other two sides is 46 miles

Thus, length of second side  = x - 46

Applying the pythagoras theorem we get,

Hypotenuse² = one side² + second side²

Putting the values we get,

130 = x² + ( x - 46 )²

Expanding the brackets we get,

16,900 = x² + x² - 92x + 2116

Solving we get,

16,900 = 2x² - 92x + 2116

Or, we can write

2x² - 92x + 2116 - 16,900 = 0

Thus we get,

2x² - 92x - 14784 = 0

Dividing the whole equation by 2 we get,

x² - 46x - 7392 = 0

Solving the above quadratic equation,

x² + 112x - 66x - 7392 = 0

x( x + 112) - 66 (x + 112) = 0

Taking common we get,

(x - 66) (x + 112) = 0

Thus,

x = 66 , -112

Since the length cannot be negative, then

x = 66 miles

Length of second side is

66 - 46 = 20 miles

Thus, the required value of the missing side is 66 miles and 20 miles.

Step-by-step explanation:

The equation of the line is: y = -3/5x + 1.

The slope (m) of two lines that lie perpendicular to each other are negative reciprocals.

Given, y = 5/3x - 3, the slope (m) of the line is 5/3. The negative reciprocal of 5/3 is -3/5.

Thus, the line that is perpendicular to it will have a slope (m) of -3/5.

Substitute m = -3/5 and (a, b) = (5, -2) into y - b = m(x - a):

y - (-2) = -3/5(x - 5)

y + 2 = -3/5x + 3

y + 2 - 2 = -3/5x + 3 - 2

y = -3/5x + 1

Thus, the equation of the line is: y = -3/5x + 1.

The final price Cheryl will pay for the shirt, using the mathematical expression that includes the sales tax, is $34.56.

A mathematical expression is a mathematical statement with two different numbers (known or unknown) and at least one mathematical operation.

The basic mathematical operations include addition, subtraction, division, and multiplication.

For, instance, the total cost of a T-shirt after factoring in the sales tax of 8% can be represented with this mathematical expression, T= 1.08p.

Cost of a shirt, p = $32

Sales tax = 8%

The mathematical expression of the total cost = 1.08p

Fiona has a function that shows the amount of money she has to pay ( f(.) as a function of the gas the buys (g).

So, the function can be written as: f(g).

As each litter costs $2.25 we can say that;

f(g) = 2.25g

Lets try to find put which constraints the function f(g) has in its domain, it is, what are the restrictions for the values of g.

Is evident that g cannot be negative, as one cannot buy negative liters of gasoline. We can buy any positive amount of gasoline, doesn't matter if it is an integer number or not. it is possible to buy 5 liters and also to buy 5.45454545545454 liters. A zero amount of liters is also possible, having zero cost.

Thus, as any positive or zero value is positive, but negative values are not, we can restrict the domain to every non-negative real number:

Therefore ,Domain(f) = [0, infinite ) or

     Domain(f) = Real non negative.

Using the z-distribution, it is found that:

a) The null hypothesis is [tex]H_0: p \geq 0.68[/tex] and the alternative hypothesis is [tex]H_1: p < 0.68[/tex].

b) A true null hypothesis would mean that there is not enough evidence that her ability has decreased.

c) There is not enough evidence for the alternative hypothesis.

d) This is because the test statistic is less than the critical value, and the p-value is greater than 0.05.

At the null hypothesis, it is tested if there is not enough evidence that her ability has decreased, that is, the proportion is still of at least 68%, hence:

[tex]H_0: p \geq 0.68[/tex]

At the alternative hypothesis, it is tested if there is enough evidence that her ability has decreased, that is, the proportion is less than 68%, hence:

[tex]H_1: p < 0.68[/tex]

Hence:

A true null hypothesis would mean that there is not enough evidence that her ability has decreased.

The test statistic is given by:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

In which:

For this problem, considering the situation described, the parameters are given as follows:

[tex]p = 0.68, n = 56, \overline{p} = \frac{34}{56} = 0.6071[/tex]

Hence the test statistic is:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

[tex]z = \frac{0.6071 - 0.68}{\sqrt{\frac{0.68(0.32)}{56}}}[/tex]

z = -1.17.

Considering a left-tailed test, as we are testing if the proportion is less than a value, the critical value is given by:

z* = -1.645.

The test statistic is less than the critical value, meaning that the p-value is greater than the standard significance level of 0.05 and there is not enough evidence for the alternative hypothesis.

Hence:

c) There is not enough evidence for the alternative hypothesis.

d) This is because the test statistic is less than the critical value, and the p-value is greater than 0.05.
