Answer:
D)
Step-by-step explanation:
Percentage word problems:Let the original length be 'x'.
Percentage error = 5 %
So, (100 -5)% = 95% of the original measurement is 3.99 m
95% of x = 3.99
[tex]\sf \dfrac{95}{100}*x = 3.99[/tex]
[tex]\sf x = \dfrac{3.99*100}{95}\\\\x = \dfrac{399}{95}\\\\\\x = 4.2 m[/tex]
Original length = 4.2 m
The graph of y = f(x) is graphed below. What is the end behavior of f(x)?
Answer:
(a) as x → -∞, f(x) → ∞ and as x → ∞, f(x) → ∞
Step-by-step explanation:
You want to know the end behavior of the 4th-degree function shown in the graph.
Arrows on the graphThe graph has an arrow on each end of the curve shown in the figure. The left arrow points upward, indicating a tendency to +∞ as x gets more negative.
The right arrow also points upward, indicating a tendency to +∞ as x gets more positive.
As x → -∞, f(x) → ∞ and as x → ∞, f(x) → ∞.
what are the two estimates of 1,624 divided by 3
A number is divisible by 3 it the sum of its digits is divisible by 3. In this case, we have
which is not divisible by 3. The nearest multiples of 3 are 1623 and 1626. If you divide these numbers by 3, you have
So, the result of our division is between 541 and 542.
If these numbers are too complex to divide, we have to choose easier numbers, but we will lose some accuracy. For example, we can see that 1624 is between 1500 and 1650, which are very easily divisible by 3. We have
So, the result of our division is between 500 and 550. This is still true, but as you can see it is a much looser approximation than the one before.
Anya has a change jar that contains $1.06 in pennies and dimes. The number of pennies is 10 more than two times the number of dimes. How many of each type of coin does she have?
The number of pennies that Anya has is equal to 15.6 pennies.
The number of dimes that Anya has is equal to 2.8 dimes.
How to determine the number of coins?In order to solve this word problem, we would assign variables to the number of pennies and dimes, the total number of coins, and then translate the word problem into algebraic equation as follows:
Let d represent the number of dimes.Let p represent the number of pennies.Let T represent the total number of coins.Note: 1 penny is equal to 0.05 dollar and 1 dime is equal to 0.10 dollar.
Therefore, translating the word problem into an algebraic equation, we have the following;
p = 10 + 2d ......equation 1.
0.05p + 0.1d = 1.06 .......equation 2.
Substituting equation 1 into equation 2, we have:
0.05(10 + 2d) + 0.1d = 1.06
0.5 + 0.1d + 0.1d = 1.06
0.5 + 0.2d = 1.06
0.2d = 1.06 - 0.5
0.2d = 0.56
Dimes, d = 0.56/0.2
Dimes, d = 2.8 dimes.
For the number of pennies, we have:
p = 10 + 2d
p = 10 + 2(2.8)
p = 10 + 5.6
p = 15.6 pennies.

Please explain how you get your answer so i get a better understanding of this...
Using the image below, if I is parallel to M, find the value of y.
(im really struggling with this question so please do explain your answering.)
Answer:
16.11 (appx.)
Step-by-step explanation:
since l and m are parallel and a line intersects them, so we can say that the line is the transversal. from the figure we see that
7x + 12 = 12x - 28 [they are internal alternate angles and alternate angles are always equal to one another]
now, we can find the value of x from the equation
12x - 7x = 28 + 12
⇒ 5x = 40
⇒ x = 8
so the angle (7x+12)° is ((7*8)+12) = 68°
so (12x-28)° is also equal to 68° [cause of being alternate angles]
now, look at the figure,
angle (9y-77)° & (12x-28)° add upto a straight line as in 180°
and we know (12x-28)° = 68°
so now,
9y-77 = 68
⇒9y = 68+77
⇒9y = 145
⇒y = 16.11 (appx.)
What expression represents the verbal phrase?
one-half times a number m plus twenty-five
The expression that represents the verbal phrase, one-half times a number m plus twenty-five, is m/2+25.
According to the question,
We have the following information,
The given verbal phrase is one-half times a number m plus twenty-five.
Now, we will solve it step by step.
Now, we will first find one-half times a number m. We know that we will replace the word times with multiplication. So, we have the following expression:
m/2
Now, adding 25 to this term, we have the following final expression:
m/2+25
Hence, the expression that represents the verbal phrase, one-half times a number m plus twenty-five, is m/2+25.

By evaluating a linear equation, we can see that 677.25 mL will be infused in 5.25 hours.
How many mL would infuse in 5.25 hours?We know that the solution is being infused at a rate of 2.15 mL per minute.
So, t minutes after the infusion starts, the volume infused is given by the linear equation:
V(t) = 2.15mL*t
Here we want to see how many mL would infuse in 5.25 hours, to do that, we need to write that time in hours:
We know that one hour = 60 min, then:
5.25 h = 5.25*60 min = 315 min

Katrina buys a 66-ft roll of fencing to make a rectangular play area for her dogs. Use 2(l+w) = 66 to write a function. for the length, given the width. Graph the function. What is a reasonable domain for the situation? Explain. The function f(w) = gives the length as a function of the width. (Simplify your answer.)
The function for the length when the width is given is l = 33 - w. The domain of the function is 0 < w < 33 and the graph of the function has been plotted
The total length of the roll = 66 feet
The perimeter of the rectangular paly area = 66
The perimeter of the rectangle = 2(l + w)
Then the equation will be
2(l + w) = 66
l + w = 66/2
l + w = 33
The function for length when the width is given
l = 33 - w
Therefore the domain of the function is 0 < w < 33
When w = 1
l = 33 - 1
l = 32
The first point is (1, 32)
When w = 32
l = 33 - 32
l = 1
The second point is (32, 1)
Draw the graph of the function
Hence, the function for the length when the width is given is l = 33 - w. The domain of the function is 0 < w < 33 and the graph of the function has been plotted

The value of [tex]\sqrt[5]{\frac{1024(x^{-1})^{10}}{(2x^{-3})^5} }[/tex] is 2x and the value of [tex]\frac{(8x^6y^{-3})^\frac{1}{3} }{(2xy)^3}[/tex] is 1 / 4xy^4.
First, let us know some laws of exponent:
(a²) · (a³) = a²⁺³ = a⁵(a²)³ = a²ˣ³ = a⁶(a²) ÷ (a³) = a²⁻³ = a⁻¹We are given;
[tex]\sqrt[5]{\frac{1024(x^{-1})^{10}}{(2x^{-3})^5} }[/tex] and [tex]\frac{(8x^6y^{-3})^\frac{1}{3} }{(2xy)^3}[/tex].
Now, we will solve one by one;
[tex]\sqrt[5]{\frac{1024(x^{-1})^{10}}{(2x^{-3})^5} }[/tex]
[tex]= \sqrt[5]{\frac{2^{10}(x^{-10})}{(2^5x^{-15})}}[/tex]
[tex]=[({2^{10}. 2^{-5}) (x^{-10}.x^{15})}]^\frac{1}{5}[/tex]
[tex]=[({2^{10-5}) (x^{-10+15})]^\frac{1}{5}[/tex]
[tex]=[({2^{5}) (x^{5})]^\frac{1}{5}[/tex]
= 2x
So, the value of [tex]\sqrt[5]{\frac{1024(x^{-1})^{10}}{(2x^{-3})^5} }[/tex] is 2x.
Now,
[tex]\frac{(8x^6y^{-3})^\frac{1}{3} }{(2xy)^3}[/tex]
[tex]=\frac{(2^3x^6y^{-3})^\frac{1}{3} }{(2^3x^3y^3)}[/tex]
[tex]=\frac{(2x^26y^{-1})}{(2^3x^3y^3)}[/tex]
[tex]=\frac{1}{(2^{3-1}x^{3-2}y^{3+1})}[/tex]
[tex]=\frac{1}{(2^{2}x^{1}y^{4})}[/tex]
= 1 / 4xy^4
So, the value of [tex]\frac{(8x^6y^{-3})^\frac{1}{3} }{(2xy)^3}[/tex] is 1 / 4xy^4.
Thus, the value of [tex]\sqrt[5]{\frac{1024(x^{-1})^{10}}{(2x^{-3})^5} }[/tex] is 2x and the value of [tex]\frac{(8x^6y^{-3})^\frac{1}{3} }{(2xy)^3}[/tex] is 1 / 4xy^4.

general form:
The standard form of the equation of the circle is (x-5)² + (y+3)² = 9² and the general form is x² + y² + 10x + 6y - 47 = 0 .
We know that the general form of the equation of a circle is given by the following equation:
(x-h)² + (y-k)² = r² . Where r is the radius of the circle and (h, k) is the center of the circle.
So the general equation of the circle is (x-5)² + (y+3)² = 9² .
Let's first define a circle in order to determine its equation. A circle is formed by every point in a plane that is uniformly spaced from another point.
The constant point is located at the center of the circle. The radius of a circle is the separation between its center and any point along its circumference.
(x-5)² + (y+3)² = 9²
or, x² + 10x + 25 + y² + 6y + 9 = 81
or, x² + y² + 10x + 6y - 47 = 0
