Which inequality represents all values of x for which the quotient below is defined? Square root 7x2 divide by square root 3x
Inequalities help us to compare two unequal expressions. The correct option is D.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.
The given expression can be solved as,
[tex]\dfrac{\sqrt{7x^2}}{\sqrt{3x}}\\\\= \dfrac{\sqrt{7}x}{\sqrt{3x}}\\\\= \sqrt{\dfrac{7x}{3}}[/tex]
Since the value of (7x/3) is needed to be positive, therefore, the inequality that represents all the values of x for the quotient is defined as x>1.
Hence, the correct option is D.

Answer: x>0
Step-by-step explanation:
Choose the letter of the equation for
the graph.
a. y = sin x + 2
b.y = cos x + 2
c. y = cos(x - 1)
d. y = sin(x - 1)
e. y = sin(x + "/2)
Using translation concepts, it is found that the equation represented on the graph is of:
d. [tex]y = \sin{(x - \pi)}[/tex]
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
In this problem, we have a trigonometric function, with amplitude of 1, hence there was no vertical translation, which removes options a and b.
The function is of zero at the origin, 1 at [tex]\frac{\pi}{2}[/tex] and -1 at [tex]\frac{\pi}{2}[/tex]. The sine function is of 0 at [tex]-\pi[/tex], of -1 at [tex]-\frac{\pi}{2}[/tex] and of 1 at [tex]-\frac{3\pi}{2}[/tex], hence option d is correct.

The integral in this exercise converges. Evaluate the integral without using a table 0e^0d0
The value of 0e^0d0 is -1 if the integral in this exercise converges after applying limit.
What is convergent of a series?A series is convergent if the series of its partial sums approaches a limit; that really is, when the values are added one after the other in the order defined by the numbers, the partial sums getting closer and closer to a certain number.
We are assuming the:
[tex]=\int\limits^0_{-\infty} {\theta e^{\theta}} \, d\theta[/tex]
Applying limit;
[tex]=\lim_{n \to \infty} \int\limits^0_{-n} {\theta e^{\theta}} \, d\theta[/tex]
After solving the integral:
[tex]=\lim_{n \to \infty} (e^{\theta})|^0_-_p[/tex]
= -(1-0)
= -1
Thus, the value of 0e^0d0 is -1 if the integral in this exercise converges after applying limit.

Answer:
B. 254 cm²
Step-by-step explanation:
Hello!
CircleThe formula for the area of a circle is [tex]A = \pi r^2[/tex]
A is areaπ is pi (roughly 3.14)r is the radiusThe radius is half of the diameter, given with the formula [tex]D = 2r[/tex]
AreaUsing the information, we can first solve for the radius.

what is 62.5% as a decimal
Answer:
0.625
Step-by-step explanation:
please give me brainliest :(
Answer:
0.625
Step-by-step explanation:
How to Convert a Percent to a Decimal
Here are two ways to convert a percent to a decimal,
1. Divide a percent by 100 and remove the percent sign to convert from a percent to a decimal.
Example: 62.5% becomes 62.5/100 = 0.625
2. This way is easier and faster. Start by removing the percent sign and moving the decimal point 2 places to the left.
Example: 62.5%
⇒ 62.5
⇒ 6.25
⇒ .625
Hence, the answer is 0.625.
Dalia buys a winter jacket at a used clothing store that costs $30. She lives in Idaho, where the sales tax is 6%. How much does Dalia pay in total?
A. y= 1/2x-14
B. y=1/2x-5
C. y=2x-14
D. y=2x-5
Answer:
B. y=1/2x-5
Step-by-step explanation:
From the graph, we read the slope of line JK.
slope = rise/run = -3/-6 = 1/2
The equation we need has the same slope.
y = mx + b
y = (1/2)x + b
It passes through point P(6, -2). Now we find b.
-2 = (1/2)(6) + b
-2 = 3 + b
b = -5
The equation is
y = (1/2)x - 5

Step-by-step explanation:
so,
1/12 × $100
5/12 × $20
6/12 × $1
so the expected "payout" is
100/12 + 100/12 + 6/12 = 206/12 = 103/6 ≈ $17.17
minus the $2 entrance fee, the expected value is
17.17 - 2 = $15.17
but of course, there will be 6 losing $1 (while the other 6 will go home with a positive result).

Does anybody know this? ABCD is a parallelogram BDC=110. Find the following values,
Answer:
see explanation
Step-by-step explanation:
in a parallelogram]
• opposite sides are congruent
• opposite angles are congruent
• consecutive angles are supplementary , sum to 180°
• diagonals bisect each other
Then
DC = AB = 15
BC = 2 × WC = 2 × 9 = 18
∠ BAC = ∠ BDC = 110°
∠ DCA = 180° - 110° = 70°
DC = 15 (opposite sides in a parallelogram is parallel and equal to each other)
BC = 18 (the diagonals in a parallogram bisect at their midpoints -> BW = WC = 9 -> BC = 9 + 9 = 18)
angle BAC = 110 (opposite angles are equal to each other)
angle DCA = 70 (consecutive angles add up to 180, angle BAC and angle DCA are consecutive -> 180 - 110 = 70)

Serena is taking 4 friends on a trip with her to Louisiana for spring break. They take two cars to the airport where Serena pays $7.00 per car to park. Serena is charged a total of $2114.00 for tickets and parking. She pays the same price for each plane ticket. Using an equation to help you solve, what was the price of each person’s ticket?
Answer:
$420
Step-by-step explanation:
number of people = 5 (4 friends + serena)
number of cars = 2
cost of parking = 7 for each car = 7 * number of cars = 7 * 2 = 14
let t be the cost of each ticket
cost of tickets = t for each person = t * 5
total cost = cost of parking + cost of tickets
= 14 + t * 5
= 2114
2114 = 14 + 5t
subtract 14 from both sides to isolate the variable and its coefficient
2100 = 5t
divide both sides by 5 to isolate t
t = 2100/5 = 420

96 Eight small bricks have the same mass as three large bricks The mass of one small brick is 1.5kg. What is the mass of one large brick?
Answer:
4 kg
Step-by-step explanation:
Since the mass of one small brick is 1.5 kg, the mass of 8 small bricks is 1.5 × 8, or 12 kg. Since 12 kg is the total mass of 3 large bricks, it follows that each large brick will have a mass of 12 ÷ 3, or 4 kg.
