A stuntwoman jumps from a building 73ft high and lands on an air bag that is 9ft tall. Her height above ground h in feet can be modeled by h (t) = 73 – 16 t^2, where t is the time in seconds.
a. How many seconds will the stuntwoman fall before touching the air bag? (Hint: Find the time t when the stuntwoman’s height above ground is 9 ft.)
The sum of three numbers is 62. The second number is equal to the first number diminished by 4. The third number is four times the first. What are the numbers?
Which three expressions could be used to represent the numbers?
1st number = x
2nd number = x-4
3rd number = 4x
now you have x + x-4 +4x = 62
combine like terms
6x-4 = 62
add 4 to each side
6x = 66
divide both sides by 6
x = 66/6 = 11
1st number = 11
2nd number = 11-4 = 7
3rd number = 4*11 = 44
11+7+44 = 62
How many times does 15000 go in to 3000000?
To determine how many times 15000 goes into 3000000, divide 3000000 by 15000. The answer is 200.
To find out how many times 15000 goes into 3000000, we need to perform a simple division.
We divide 3000000 by 15000:
3000000 ÷ 15000 = 200
Thus, 15000 goes into 3000000- 200 times.
Simplify the following expression 5^2-4/5+2
To simplify the expression 5^2-4/5+2, we first simplify the exponent, divide 4 by 5, and add the results together to get 129/5 or 25.8.
Explanation:To simplify the expression 5^2-4/5+2, we need to follow the order of operations which is often remembered using the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).
Using PEMDAS, we first simplify the exponent, so 5^2 = 5 x 5 = 25.
Next, we divide 4 by 5 to get 4/5.
Finally, we add 25 and 4/5 which can be written as 25 + 4/5. To add these two fractions, we need a common denominator which is 5. Converting 25 into a fraction with a denominator of 5 gives us 125/5. Adding 125/5 and 4/5 gives a result of 129/5. Therefore, the simplified expression is 129/5 or 25.8.

Answer:
[tex]\frac{11}{8}[/tex] [tex]\text{gallons}[/tex]
Step-by-step explanation:
Given: In [tex]1\frac{1}{2}[/tex] hour, a lawnmower uses [tex]2\frac{1}{16}[/tex] gallon of fuel.
To Find: How many gallons of fuel did the lawnmower use each hour.
Solution:
Number of hour lawnmower used [tex]=1\frac{1}{2}[/tex] [tex]\text{hour}[/tex]
[tex]\frac{3}{2}[/tex] [tex]\text{hour}[/tex]
Fuel consumed by lawnmower [tex]=2\frac{1}{16}[/tex] [tex]\text{gallon}[/tex]
[tex]\frac{33}{16}[/tex] [tex]\text{gallon}[/tex]
Fuel used by lawnmower each hour [tex]=\frac{\text{Total fuel used}}{\text{Total time taken}}[/tex]
[tex]=\frac{\frac{33}{16}}{\frac{3}{2}}[/tex]
[tex]=\frac{11}{8}[/tex] [tex]\text{gallon}[/tex]
Hence the fuel consumed by lawnmower each hour is [tex]=\frac{11}{8}[/tex] [tex]\text{gallon}[/tex]
Which expression is equal to 2√ -32 ? 8i√2 −8√2 8√2i −8i√2
the first one is the answer
Final answer:
The expression 2√ -32 is equal to 8i√2
Explanation:
To find an expression equal to 2√ -32, we need to recall that the square root of a negative number involves an imaginary unit i. The square root of -1 is defined as i. Thus, we can rewrite the expression as:
2√ -32 = 2√(-1 × 32) = 2√(-1)√(32) = 2i√(16 × 2) = 2i × 4√2 = 8i√2.
which is found by using the property that the square root of -1 is the imaginary unit i.
This demonstrates that the correct expression equivalent to the original one is 8i√2.

Standard deduction on federal income tax return for head of the household is $8350. hilda, a single mom of two, paid $6780 in state income tax and $1230 in mortgage interest last year. how should she file her taxes?
The answer is Claiming standard deduction
Answer:
Hilda can file her taxes by claiming standard deduction.
Step-by-step explanation:
Standard deduction is that amount of someone's income, for which tax is not to be paid, thus reducing the tax bill amount. The amount of the standard deduction is based on one's filing status, age, disability, dependency etc.
Here in this scenario, Hilda can claim standard deductions.

The function c = 2.50(n – 2) + 4.50 represents the cost c in dollars of printing n invitations. Which of the following is not true?
A/Each invitation costs $4.50 to print.
B/The cost depends on the number of invitations printed.
C/For each additional invitation, it costs an extra $2.50 to print.
D/One cannot print just one invitation.
The equation c = 2.50(n - 2) + 4.50 represents the cost of printing n invitations, with $4.50 being a fixed cost and $2.50 as the additional cost per invitation after the first two. Thus, the statement that A. each invitation costs $4.50 to print is not true.
The function in question, c = 2.50(n – 2) + 4.50, represents the total cost c of printing n invitations. To determine which of the provided statements is not true, we can analyze the components of the equation:
4.50 is a fixed cost, indicating a base charge that is applied regardless of the number of invitations printed.The term 2.50(n – 2) shows that each additional invitation, beyond the first two, incurs a variable cost of $2.50.Analyzing the provided options:
Each invitation costs $4.50 to print. This statement is false, as the $4.50 in the equation is a fixed cost and not reflective of the individual cost per invitation.The cost depends on the number of invitations printed. This is true as the cost increases with each additional invitation after the first two.For each additional invitation, it costs an extra $2.50 to print. This is true given the variable cost component of the equation.One cannot print just one invitation. There is nothing in the equation that inherently prevents printing one invitation, so this statement is true.Therefore, the answer to the student's question is option A: Each invitation costs $4.50 to print is not true.

Determine the x- and y-intercepts of the graph of y=−12x−4 . Then plot the intercepts to graph the equation.
Answer:
X-Intercept: [tex]\frac{4}{-12}[/tex]
Y-Intercept: -4
Step-by-step explanation:
Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.
The X and Y intercepts show at what points the function values cross the X and Y axis. We can solve for the X-intercept by substituting the value of y for 0 and then solving for x. Like so...
[tex]0=-12x-4[/tex] .... add 4 on both sides
[tex]4=-12x[/tex] ... divide both sides by -12
[tex]\frac{4}{-12}[/tex] = -x
Now we can see that the X-Intercept is [tex]\frac{4}{-12}[/tex] . Now we substitute 0 for x and solve for the Y-intercept.
[tex]y=-12(0)-4[/tex]
[tex]y= -4[/tex]
Finally we can see that the Y-intercept is -4

Prove the diagonals of the square with vertices P (0,4), Q (4,4), R (0,0) and S (4,0) are perpendicular bisectors of each other.
Step 1: calculate the slope of the diagonals.
The slope of diagonal PS is ____
The slope of diagonal QR is ____
Step 2: calculate the midpoint of the diagonals
The midpoint of PS is ___
Midpoint of QR is ___
The diagonals are perpendicular because the product of their slope is -1, and their midpoint is same (2,2). Hence, it is proved that the diagonals of the given square are perpendicular bisectors of each other.
Given information:
The square with vertices P (0,4), Q (4,4), R (0,0) and S (4,0).
It is required to prove that the diagonals of the given square are perpendicular bisectors.
First, calculate the slope of the diagonals.
The slope of diagonal PS will be,
[tex]m = \dfrac{0-4}{4-0}\\m = -1[/tex]
So, the slope of diagonal PS is -1.
The slope of diagonal QR will be,
[tex]m' = \dfrac{0-4}{0-4}\\m' = 1[/tex]
So, the slope of diagonal QR is 1.
From the slope of the diagonals, the diagonals are perpendicular because the product of slope is -1.
Now, it is required to find the mid-point of the diagonals.
The midpoint of PS will be,
[tex](x,y)=(\dfrac{0+4}{2},\dfrac{4+0}{2})=(2,2)[/tex]
Midpoint of QR will be,
[tex](x,y)=(\dfrac{4+0}{2},\dfrac{4+0}{2})=(2,2)[/tex]
So, the midpoint of both the diagonals is also same.
Therefore, it can be said that the diagonals are perpendicular because the product of their slope is -1, and their midpoint is same (2,2). Hence, it is proved that the diagonals of the given square are perpendicular bisectors of each other.
