Can you translate a mathemetical expression into a verbal expression?
Answer:
Yes, you can translate a mathemetical expression into a verbal expression.
Step-by-step explanation:
If that explantion was not helpful, you can always read out the equation verbally. For example, you can say that "three more than x" can be written as an algebraic expression. x + 3 x+ 3 x+3 .
In the figure, lines m and n are parallel to each other. Lines p and q are also parallel to each other.
The value of x is ????? degrees, and the value of y is ??????? degrees.
The value of X is 112° and The value of Y is 68°
Answer:
Angle y: 68°
Angle x: 112°
Step-by-step explanation:
When you are dealing with two sets of parallel lines where one set intercepts the other, angles are always the same as the parallel line's angle. In this example
∡PM = 68° = ∡y°
Seeing that we now know that y is 68° and q is a straight line (Straight Lines have an angle of 180°) we can subtract 68° from 180° in order to get the degree of the angle x.
180° - 68° = 112°
Now we know that angle y is 68° and angle x is 112°

Given a cone with a volume of 56.52 in^3 and height 7 in., find the base radius of the cone.Use 3.14 for pi. Round your answer to the tenths place. a. 2.1 in c. 4.9 in b. 2.8 in d. 4.3 in
Answer:
B
Step-by-step explanation:
Volume of Cone formula is given by : [tex]V=\frac{1}{3}\pi r^2 h[/tex]
Given V = 56.52 and h = 7, we plug them in and solve for r:
[tex]V=\frac{1}{3}\pi r^2 h\\56.52=\frac{1}{3}(3.14) r^2 (7)\\56.52=7.33r^2\\\frac{56.52}{7.33}=r^2\\7.71=r^2\\r=\sqrt{7.71}\\ r=2.77[/tex]
rounding to tenths place, r = 2.8 inches
Answer choice B is right
Answer: c. [tex]4.9\ in.[/tex]
Step-by-step explanation:
The volume of cone is given by :-
[tex]V=\dfrac{1}{3}\pi r^2 h[/tex], where r is radius and h is height of the cone.
Given: Height : 7 in.
Volume : [tex]56.52\ in^3[/tex]
Then the volume of the cone will be :-
[tex]56.52=\dfrac{1}{3}(3.14) r^2(7)\\\\\Rightarrow\ r^2=\dfrac{56.52\times3}{7\cdot3.14}\\\\\Rightarrow\ r^2=24.22285714\\\\\Rightarrow\ r=4.921672189\approx4.9\ in.[/tex]
Hence, the radius of the cone = [tex]4.9\ in.[/tex]

The value of a stock increases at a rate of 1/2% per year. If the initial value of the stock $40 a share, when will the value of the stock be $50? Round your answer to the nearest tenth of a year
Answer:
After 50 years the stock value will be $50 per share.
Step-by-step explanation:
Simple Interest Equation (Principal + Interest)
A = P(1 + rt)
Where:
A = Future amont = $50
P = Principal Amount = $40
r = Rate of Interest per year in decimal; r = R/100 = 0.5/100 = 0.005
t = Time Period involved in months or years
Plug in the values
50 = 40(1 + 0.005t)
50 / 40 = (1 + 0.005t)
5/4 = 1 + 0.005t
5/4 - 1 = 0.005t
0.25 = 0.005t
t = 0.25 / 0.005
t = 50 years
Answer:
44. 7 yr
Step-by-step explanation:
The compound interest equation is
[tex]A = P(1+ \frac{r }{ n})^{nt}[/tex]
You don't give the frequency of compounding, so I will assume that it is once per year.
Data:
P = $40
r = 0.5 % = 0.005
n =1
Calculations:
(a) Calculate A
A = P + I = 40 + 10 = $50
(b) Calculate t
[tex]50 = 40(1+ \frac{0.005 }{ 1})^{1 \times t}\\50 = 40(1+ 0.005)^{t}[/tex]
Divide each side by 40
[tex]1.25 = 1.005^{t}[/tex]
Take the logarithm of each side
log1.25 = tlog1.005
0.09691 = 0.002 166t
Divide each side by 0.002 166
t = 44.7 yr
The value of the stock will be $50 in 44.7 yr.

A person has body fat percentage of 17.2% and weighs 171 pound how many pounds of her weight is made up of fat
Answer: 29.41 pounds
Step-by-step explanation:
You have the following information given in the problem:
- The fat percentage that the person has is 17.2%
- The person weighs 171 pounds.
Therefore, to calculate the amount of pounds of her weight is made up of fat (which you can call x), you must multiply the weight of the person by the fat percentage.
Therefore, you obtain the following result:
[tex]x=171lb*0.172\\x=29.41lb[/tex]
f(x)=1/x-5, g(x)=5x-1/x A. Use composition to prove whether or not the functions are inverses of each other. B. Express the domain of the compositions using interval notation.
Answer:
Not inverse of each other
Domain : [-∞,0) U (0,5) U (5,∞]
Step-by-step explanation:
Given in the question two functions
f(x)=1/x-5
g(x)=5x-1/x
To find that each of them are inverse of each other we will use composition
f(g(x))[tex]\frac{1}{\frac{5x-1}{x}-5 }[/tex]
take LCM
[tex]\frac{1}{\frac{5x-1-5x}{x}}[/tex]
5x will be cancel
[tex]\frac{1}{\frac{-1}{x}}[/tex]
1 ÷ (-1/x)
1 × (-x/1)
-x
Now,
g(f(x))[tex]\frac{5\frac{1}{x-5} -1}{\frac{1}{x-5}}[/tex]
[tex]\frac{5}{x-5} -1}[/tex] × [tex]5-x[/tex]
[tex]\frac{5-x+5}{x-5} * (x-5)[/tex]
10-x
As it ended up with different answers, so f(x) and g(x) are not inverse of each other
The domain are all the possible x-values of function except x ≠ 0 and x ≠ 5
We can conclude that the domain of the composition function is
Domain : [-∞,0) U (0,5) U (5,∞]
To prove whether or not the functions f(x) = 1/(x-5) and g(x) = (5x-1)/x are inverses of each other, we need to show that their compositions result in the identity function. We also need to find the domain of the compositions f(g(x)) and g(f(x)).
Explanation:To prove whether or not the functions f(x) = 1/(x-5) and g(x) = (5x-1)/x are inverses of each other, we need to show that their compositions result in the identity function. Let's start by finding the composition f(g(x)):
Plug in g(x) into f(x): f(g(x)) = f((5x-1)/x)Simplify f(g(x)) by substituting (5x-1)/x into the expression for f(x)Simplify further to obtain the composition f(g(x)) as a function of xNow, we need to find the composition g(f(x)): g(f(x)) = g(1/(x-5))
Follow the same steps as above to simplify g(f(x)) as a function of x. If the compositions f(g(x)) and g(f(x)) both result in the identity function, then the functions f(x) and g(x) are inverses of each other.
To express the domain of the compositions f(g(x)) and g(f(x)), we need to consider the restrictions on the domains of the individual functions. The domain of f(g(x)) will be the values of x for which (5x-1)/x is defined, and the domain of g(f(x)) will be the values of x for which 1/(x-5) is defined.

Answer:
x = 75 degrees
Step-by-step explanation:
155 and the angle next to it makes 180 degrees
To find the missing angle take 180 and subtract 155
180 - 155 = 25
All the angles in the upper triangle are 25, 80 and x
To find x add 80 and 25
80 + 25 = 105
A triangle equals 180 degrees so subtract 105 from 180 to get x

A supervisor set the following performance goal for new employees: re-stock an average of 42 products per day for the entire work week (Monday thru Friday). Today is Friday and Employee A has re-stocked 185 products so far this week. How many products will Employee A need to re-stock today to meet the goal?
Answer:
25 more items
Step-by-step explanation:
Employees need to stock at least 42 each day for a whole week or work. (5 days) so wee need to find how much they need to stock in a week.
42 x 5 = 210.
So They need to stock 210. Employee A has already stocked 185. so we need to take 185 from 210 to see how MORE he needs to stock.
210 - 185 = 25.
25.
Hope this helped! Please mark as brainliest! THanks!
In order to be able to make the goal that was set for the employee, the employee would have to re-stock 25 products.
The worker is supposed to stack an average of 42 products from Monday to Friday which is 5 days.
Technically speaking, in every one of those 5 days, 42 products should be stocked. The total for the week is therefore:
= 5 days x Number of products stocked per day
= 5 x 42
= 210 products
The worker has stocked 210 products already and so is left with:
= Number to be stocked - Number already stocked
= 210 - 185
= 25 products
In conclusion, the worker still has to re-stock 25 products.

Students are using the graph to find the solution to the system y=3 and y=-2x+1. Anthony says the solution to the system is (3,-5). April says the solution to the system is (-1,3).
Answer: April is correct.
Step-by-step explanation: According to the methods used in systems of equations, if we are to solve this system by setting up the equations
(3 = -2x + 1), we see that the solution is x = -1. If you substitute this x-value back into the original equation, y = -2x + 1, we get the answer y = 3 and thus, receiving the solution to the system (-1,3). Anthony is wrong because the graph includes an extra line at x = 3, throwing off his answers.
Find an equation in standard form for the hyperbola with vertices at (0, ±10) and asymptotes at y = ±five divided by four times x..
Answer:
The equation of the hyperbola in standard form is
[tex]\frac{y^{2}}{100}-\frac{4x^{2}}{625}=1[/tex]
Step-by-step explanation:
* We will take about the standard form equation of the hyperbola
- If the given coordinates of the vertices (0 , a) and (0 , -a)
∴ The transverse axis is the y-axis. (because x = 0)
- If the given asymptotes at y = ± (b/a) x
∴ Use the standard form ⇒ y²/a² - x²/b² = 1
* Lets use this to solve our problem
∵ The vertices are (0 , 10) and (0 , -10)
∴ a = ±10
∴ a² = 100
∵ The asymptotes at y = ± 5/4 x
∴ ± 5/4 = ± b/a
∵ a = ± 10
∴ ± 5/4 = ± b/10 ⇒ using cross multiplication
∴± (4b) = ± (5 × 10) = ± 50 ⇒ divide both sides by 4
∴ b = ± 25/2
∴ b² = 625/4
* Now Lets write the equation
* y²/100 - x²/(625/4) = 1
∵ x² ÷ 625/4 = x² × 4/625 = (4x²/625)
∴ y²/100 - 4x²/625 = 1
* The equation of the hyperbola in standard form is
[tex]\frac{y^{2}}{100}-\frac{4x^{2}}{625}=1[/tex]

Brett kicks a field goal with an initial vertical velocity of 42m/s.how long will it take the football to hit the ground?
Answer:
C
Step-by-step explanation:
You are making a couple of assumptions. The first is that since the given has units of m/s that requires an acceleration based in m/s^2. That eliminates choices A and B. 16 is usually associated with f/s^2
Second, you are assuming 42m/s is positive and the acceleration due to gravity is negative. It doesn't matter as long as they are opposite.
Third, you are assuming that 42 m/s is the vertical acceleration. If it is not then some sort of trigonometry is needed. Since your choices don't offer trig then this assumption must be taken care of.
So the correct answer is C.
