Solve inequality for X
x-c/d > y (For d > 0)
A. x < dy - c
B. x > dy - c
C. x < dy + c
D. x > dy + c
Answers
Answer:
D. x > dy + c.
Step-by-step explanation:
To solve the inequality x - c/d > y, we'll isolate the variable x.
First, let's multiply both sides of the inequality by d:
d(x - c/d) > dy
Expanding the left side:
dx - c > dy
Next, let's rearrange the terms to isolate x:
dx > dy + c
Finally, divide both sides of the inequality by d:
x > dy/d + c/d
Therefore, the solution to the inequality x - c/d > y, for d > 0, is:
x > dy/d + c/d

Exercise 1. How fast does the level of the water contained in a cylindrical tank drop if we are emptying it at a rate of 3000 liters per minute?
Solution
Let r be the radius of the cylinder and h be the height measured in decimeters. Let V(t) be the volume of water, measured in liters (=dcm3), that is in the cylinder at time t measured in minutes. The information they give us is a variation rate
V(t + 1) − V(t) = −3000 liters per minute
In this type of exercise, the variation rate is interpreted as a derivative: V ′(t) = −3000. Notice that V(t + to) − V(to) u V′(to)t, so the interpretation is reasonable. The negative sign of the derivative is required since the volume decreases with time. Since the radius is constant but the height of the water depends on time, we have
and we deduce therefore
V(t) = πr2h(t)
V′(t) = −3000 = πr2h′(t)
h′(t) = −3000 decimeters per minute πr2
If we express the measurements in meters, then h ′ (t) = − 3 meters per minute. πr2
Exercise 2. A point P moves on the part of the parabola x = y 2 situated in the first quadrant in such a way that its x coordinate is increasing at a rate of 5 cm/sg. Find the speed at which point P recedes from the origin when x = 9.
Miguel Martín and Javier Pérez (University of Granada)
Solved exercises chapter 2 2 Solution
Let (x(t), y(t)) be the coordinates, measured in centimeters, of the point P at the instant t measured in seconds. They tell us that y(t) > 0 and that x(t) = y(t)2. The distance from point P to the origin is given by f (t) = px(t)2 + y(t)2 , so
′ x(t)x ′(t) + y(t)y ′(t) f (t) = px(t)2 + y(t)2
What we are asked for is f ′(to) knowing that x(to) = 9. In this case it must be y(to) = 3. We also know x′(t) = 5 (cm/sg). With this it is easy to deduce the value of y′(to) = x′(to) = 5. Finally,
2y(to) 6
′ x(to)x′(to)+y(to)y′(to) 45+3(5/6) 95
f (to)= px(to)2+y(to)2 = 81+9 =6√10 cm/s sorry is a lot

Which is the result of this dilation?
Enlargement
Reduction
Congruent image
What is the scale factor?
2
1/2
3/2
3
Answers
Answer:
The result of this dilation is an enlargement. The scale factor is 3.
Step-by-step explanation:
The original figure has coordinates (0,0), (1,0), (2,0), (2,1), and (1,1). The dilated figure has coordinates (0,0), (3,0), (6,0), (6,3), and (3,3). Notice that the distances between corresponding points in the original and dilated figures are all multiples of 3. This means that the dilation has a scale factor of 3.
In general, a dilation is an enlargement if the scale factor is greater than 1, a reduction if the scale factor is less than 1, and a congruent image if the scale factor is equal to 1.

HELPPPPP
Answers
The smallest number is the one closest to zero, or after zero, if it's a negative number, while the largest number is the number with the largest difference from the smallest, or the highest of value (not considering all situations). Usually, you would use the ascending order method for graphing numbers based on their value, which is indeed smallest to largest. According to thefreedictionary.com, "A function or variable continuously approaching zero as a limit." Tip: In ordering numbers based on value, the whole numbers that aren't negative are considerably believed to be the easiest numbers to order.
With that being said, here is the order of the numbers from smallest to largest:
4.38

Answers
Answer:
396 formula 72/50 x 275 please give brainliest
Step-by-step explanation:
Answer:
396 tacos
Step-by-step explanation:
for 50 people 72 tacos were sold
for 275 people a tacos were sold
50 people = 72 tacos
275 people= a tacos
cross multiplying
50 × a = 72 × 275
50a = 19800
diving both sides by 50
50a ÷ 50= 19800÷50
a=396 tacos
therefore if 275 people came,396 tacos will be sold

Answer: The answer is 7^10
Step-by-step explanation:
7^15/7^5 evaluated is 282475249
After evaluating 7^15/7^5 we could then use the process of elimination
- 7^3 = 343
- 7^10 = 282475249
- 7^20 = 1341068619663960000000
and 7^75 = 2.41186503 * 20^63
So, the answer is 7^10

Answer:

Step-by-step explanation:

2÷8= 0.25
2 yellow sections and 8 total colored sections.
Answer:
0.25
Step-by-step explanation:
Theoretical probability refers to the likelihood of an event occurring based on mathematical calculations and assumptions, without any actual experimentation or observation.
To calculate theoretical probability, divide the number of times an event can occur by the total number of possible outcomes.
[tex]\boxed{\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}}[/tex]
If the spinner is divided evenly into 8 sections, where 2 sections are yellow:
The number of ways the spinner can land on yellow is 2.The total number of possible outcomes is 8.Therefore, the theoretical probability of the spinner landing on yellow is:
[tex]\sf P(yellow)=\dfrac{2}{8}=0.25[/tex]

The value of x in the regular polygon is 15.4.
What is the value of x?
The value of x is calculated as follows;The sum of the interior angles of a polygon with n sides is given by the formula;(n-2) x 180
Since the regular polygon in question can be decomposed into 46 triangles, it has 46 x 3 = 138 sides.The value of each interior angle is calculated as;= (n - 2) x 180 / n = (138 - 2) x 180 / 138 = 169.6⁰9.5x + 26.2 = 169.69.5x = 143.4x = 15.1

And then multiply it by 15.0.55 × 15 = $8.25
Or, we can simply multiply $55 by 0.15 as given in the second option.$55 × 0.15 = $.25

Answers
Answer:
Step-by-step explanation:
yes
Answer:
First, we need to convert the lengths of the run and rise to inches. 6 ft 8 in. is equal to 72 + 8 = 80 in. and 2 ft 9 in. is equal to 24 + 9 = 33 in.
The guidelines state that the ramp should have a maximum of 1 in. of rise for every 12 in. of run. So, if the ramp has a run of 80 in., the maximum rise should be 80/12 = 6.67 in.
The ramp at the left has a rise of 33 in., which is greater than the maximum of 6.67 in. Therefore, the ramp does not meet the guidelines.
