Answer:
3.06 meters
Step-by-step explanation:
The first thing you want to do, since we are working with different units here, is find out how many centimeters make a meter... and so on.
1cm = 0.01m
1mm = 0.001m
123cm = 1.23m (Dressing table)
410mm = 0.41m (Cupboard door)
Now all we need to do is subtract.
We can add the two numbers together or (If you prefer) subtract separately.
1.23 + 0.41 = 1.64
Now subtract that number from the measurement of the wall:
4.7 - 1.64 = 3.06
The amount of space left is 3.06m.

For the given quadratic equation we have:
a) F(-2) = 5
b) F(3) = 40
c) the solutions are:
t = -1
t = -1/3
How to evaluate the quadratic function?Here we have the following quadratic function:
F(t) = 3t^2 + 4t + 1
a) First, we want to determine the value of F(-2), to do so, we just need to replace the values of the variable, t, by the number -2, we will get:
F(-2) =3*(-2)^2 + 4*(-2) + 1
F(-2) = 3*4 - 8 + 1 = 5
F(-2) = 5
b) Now we want to find the value of the F(3), so this time we evaluate in x = 3.
F(3) =3*3^2 + 4*3 + 1
F(3) = 27 + 12 + 1 = 40
F(3) = 40
c) Last, we want to solve:
F(t) = 0
So we need to solve the quadratic equation:
3t^2 + 4t + 1 = 0
Using the quadratic formula we will get the two solutions:
[tex]t = \frac{-4 \pm \sqrt{4^2 - 4*3*1} }{2*3} \\\\t = \frac{-4 \pm 2}{6}[/tex]
Then the two solutions are:
t = (-4 + 2)/6 = -2/6 = -1/3
t = (-4 - 2)/6 = -1

On the coordinate plane, point F is located at (x, 8) and point G is located at (1, 4). The
distance between points F and G is √ √52 units.
What are the two possible locations of point F?
Answer:
Step-by-step explanation:
[tex]a^{2} + b^{2} = c^{2} \\4^{2} +b^{2} = (\sqrt{52} )^{2} \\16 + b^{2} = 52\\b^{2} =36\\\sqrt{b^2} =\sqrt{36} \\b=6\\[/tex]
One of the possible x-values of point F will be 6 units to the right of point G. So, the x-value of point F could be 7, since 1+6=7. That means one possible location of point F is (7,8).
The other possible x-value of point F will be 6 units to the left of point G. So, the x-value of point F could be -5, since 1–6=–5. That means the other possible location of point F is (–5,8).
So the answer is:
(7,8) and (-5,8)
"A toy rocket is shot vertically into the air from a launching pad 7 feet above the ground with an initial velocity of 72 feet per second. The height in feet, of the rocket above the ground at t seconds after launch is given by the function h(t)=-16 t²+72 t+7. How long will it take the rocket to reach its maximum height? What is the maximum height?
The rocket reaches its maximum height at second(s) after launch.
(Simplify your answer.)
The maximum height reached by the object is feet.
(Simplify your answer.)"
Answer:
2.25 seconds ; 88 feet
Step-by-step explanation:
the maximum height of the rocket is the vertex of the parabola
x coordinate = -72/2(-16)
-72/-32 = 2.25 seconds
y coordinate = -16(2.25)^2 + 72(2.25) + 7
-81 + 162 + 7

The linear function that shows the proportional relationship between the distance and time is d = 100t
Linear FunctionA linear function is a function that represents a straight line on the coordinate plane. For example, y = 3x - 2 represents a straight line on a coordinate plane and hence it represents a linear function. Since y can be replaced with f(x), this function can be written as f(x) = 3x - 2.
A linear function is of the form f(x) = mx + b where 'm' and 'b' are real numbers. Isn't it looking like the slope-intercept form of a line which is expressed as y = mx + b? Yes, this is because a linear function represents a line, i.e., its graph is a line. Here,
'm' is the slope of the line'b' is the y-intercept of the line'x' is the independent variable'y' (or f(x)) is the dependent variableFrom the table given, we can find the slope of the function by using the formula
m = y₂ - y₁ / x₂ - x₁
m = 300 - 200 / 3 - 2
m = 100
To find the y - intercept,
y = mx + c
300 = 100(3) + c
300 = 300 + c
c = 300 - 300
c = 0

What is the linear equation?
A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are present. The variables in the above equation are y and x, and it is occasionally referred to as a "linear equation of two variables."
a) The independent variable in this problem is the number of days, represented as x. The amount of money left, the y variable is the dependent variable since it depends on the number of days left (x).
b) If there are 10 days left, we can plug it into the given equation to find the balance in the account.
y = -3x + 44
y = -3(10) + 44
y = -30 + 44
y = 14

Anthony (30) will use the single filing status for 2021. His only income for the year was from wages. In early 2022, he received the following Form W-2 from his employer. He comes to you to have his taxes prepared, and he tells you he would like to contribute to a traditional IRA for 2021, but only if he is eligible to deduct the amount. He has no other adjustments to income. What is the largest amount Anthony can contribute and deduct if he makes the IRA contribution before the filing deadline? (Answer choices are below the image.)
Since Anthony is 30, the largest amount he can contribute and deduct from his Form W-2 for the traditional IRA for 2021 is $6,000.
What is the traditional IRA?The traditional IRA or individual retirement account is a pre-tax contribution an employee saves towards retirement.
With a traditional IRA, Anthony can contribute pre- or after-tax dollars, allowing his savings to grow tax-deferred while withdrawals are taxed as current income unless after the age of 59½.
An additional tax of 10% may apply if Anthony withdraws from his traditional IRA before reaching 59½ years.
However, one advantage of the traditional IRA is that the employee invests more funds upfront since the deduction is mostly made before tax.
Thus, I will advise Anthony to deduct a maximum of $6,000 from Form W-2 towards his traditional IRA to save more money in advance.

Ezra works two summer jobs to save for a laptop that costs at least $1100. He charges $15/hr to mow lawns and $10/hr to walk dogs. This situation is modeled by: 15x + 10y ≥ 1100.
Suppose Ezra decides to also spend more than $80 on a printer. The inequality becomes
15x + 10y
.
The new inequality which represent Ezra's situation is 15x + 10y > 1180
How to write inequality?Cost of the laptop = at least $1100Amount Ezra charge to mow lawns per hour = $15Amount Ezra charge to walk dogs per hour = $10If
Hours spent to mow lawns = xHours spent to walk dogs = yThe inequality:
15x + 10y ≥ 1100
If Ezra decides to also spend more than $80 on a printer, that is, the amount spent on a printer is greater than $80
Adding an amount greater than $80 to the inequality,
It becomes 15x + 10y > 1180
Note the change in sign from greater than or equal to (≥) to greater than (>)

Approximately 71% of the Earth’s surface is water. The total surface area of the Earth is approximately 5.1 x 1014 m2. How many square meters of the Earth’s surface is not water?
Answer:
1.5 × 10^14 m²
Step-by-step explanation:
71% of the surface is covered with water.
The total surface of the Earth is 100% of the surface.
100% - 71% = 29%
29% of the surface is not covered with water.
29% of 5.1 × 10^14 m² =

Lisa Steamer is married, earns $290.34 weekly as a receptionist, and claims no allowances.
The total amount remaining after the deduction of $14.5 from $290.34 is $275.823.
What is interest?When the loan is given to you, then some amount is charged to you for the principal amount and that is called interest.
Given:
Lisa Steamer is married, earns $290.34 weekly as a receptionist, and claims no allowances.
As we know that there will be a 5% of deduction of tax,
Calculate the amount after the tax deduction,
Amount = 5 / 100 × $290.34
Amount = $14.5
The remaining amount after tax deduction = 290.34 - 14.5 = $275.823
Therefore, the total amount remaining after the deduction is $275.823.

Write a linear function f with f(-3)=1 and f(13)=5.
Answer:

Step-by-step explanation:
A linear equation is of the form ax+b. Set a up a system of equation with -3 and 13 substituted in to ax+b. We get -3a+b=1 and 13a+b=5. Solving tis gives us a,b=(0.25,1.75)
Answer:
f(x) = [tex]\frac{1}{4}[/tex] x + [tex]\frac{7}{4}[/tex]
Step-by-step explanation:
a linear function has the form
f(x) = ax + b ( a and b have to be found )
given f(- 3) = 1 and f(13) = 5 , then by substitution
- 3a + b = 1 → (1)
13a + b = 5 → (2)
subtract (2) from (1) term by term to eliminate b
- 3a - 13a = 1 - 5
- 16a = - 4 ( divide both sides by - 16 )
a = [tex]\frac{-4}{-16}[/tex] = [tex]\frac{1}{4}[/tex]
substitute a = [tex]\frac{1}{4}[/tex] into (1) and solve for b
- 3( [tex]\frac{1}{4}[/tex] ) + b = 1
- [tex]\frac{3}{4}[/tex] + b = 1 ( add [tex]\frac{3}{4}[/tex] to both sides )
b = 1 [tex]\frac{3}{4}[/tex] = [tex]\frac{7}{4}[/tex]
