Answer:
Any 2 circles in the plane are similar.
Step-by-step explanation:
No, I disagree.
Any 2 circles in the plane are congruent only when their diameters have equal length.
Any 2 circles in the plane are similar.
A plane started on the ground at ground level near the ocean. Upon taking off it climbed 9000 meters and leveled off. At the same time a submarine left from the same shoreline. It dove 250 meters down into the ocean. How many meters are there between the plane and the submarine.
(Integers / Dividing )
Answer:
Step-by-step explanation:
you just add 9000 to 250 which is equals to 9250 the clue was at the very bottom. "How many meters are there between the plane AND the submarine" 'and' is automatically addition.

Determine which of following points lie in the solution set of the inequality y >= 2x-4 and which do not. Justify each choice.
a) (5,4)
b) (0,1)
c) (10,16)
d) (2,-1)
The points lie on the given inequality y ≥ 2x-4 are (0,1) and (10,16)
What is inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given that an inequality y ≥ 2x-4
We need to check whether the given points lie on the solution of the inequality or not,
1) (5, 4)
Put x = 5
2×5-4 = 10-4 = 6
4 ≥ 6, this is a contradiction which means (5, 4) do not lie on the solution,
2) (0, 1)
Put x = 0
2×0 - 4 = 0-4 = -4
1 ≥ -4, satisfying the condition hence lies on the solution.
3) (10, 16)
Put x = 10
2×10-4 = 20-4 = 16
16 = 16. satisfying the condition hence lies on the solution.
4) (2, -1)
Put x = 2,
2×2-4 = 4-4 = 0
-1 ≥ 0, this is a contradiction which means (5, 4) do not lie on the solution,
Hence, points lie in the solution set of the inequality are (0,1) and (10,16)

What is the y intercept of the following equation -y+x=0
Answer:
0
Step-by-step explanation:
Answer:
y-intercept is 0
Step-by-step explanation:
because well you first have to put it in y=mx+b form, after you do that you have -y=0-x and you can't have a -y so you divide by -1 for 0 and -x 0/-1=0 and -x/-1=1 hope that helps

use the chain rule to calculate y = (2u² + 3)⅓ and u = √(2x +1)
full method
Answer:
Given the reference to the chain rule, I assuming by "calculate", you mean "take the derivative of", in which case we have:
For the first function:
[tex]y = (2u^2 + 3)^{\frac{1}{3}}\\\\\frac{dy}{du} = \frac{1}{3}(2u^2 + 3)^\frac{-2}{3}(4u)\\\\\frac{dy}{du} = \frac{4u}{3}(2u^2 + 3)^\frac{-2}{3}\\\\\frac{dy}{du} = \frac{4u}{3(2u^2 + 3)^\frac{2}{3}}[/tex]
and for the second one:
[tex]u = \sqrt{2x + 1}\\\\u = (2x + 1)^{0.5}\\\\\frac{du}{dx} = 0.5(2x + 1)^{-0.5}(2)\\\\\frac{du}{dx} = \frac{1}{\sqrt{2x + 1}}[/tex]

You are buying plants and soil for your garden. The soil cost $4 per bag and the plants cost $10 each. You want to buy at least 5 plants and can spend no more than $100. Write a system of linear inequalities to model the situation.
Answer:
The system of linear inequalities to model the situation is written as:
x + y ≥ 5..... Equation 1
4x + 10y ≤ 100..... Equation 2
Step-by-step explanation:
Let
The number is soil = x
The number of plants = y
You are buying plants and soil for your garden.
You want to buy at least 5 plants
At least = greater than or equal to with the inequality sign(≥)
Hence:
x + y ≥ 5..... Equation 1
The soil cost $4 per bag and the plants cost $10 each and can spend no more than $100.
No more than means Less than or equal to with the inequality sign( ≤ )
Hence:
$4 × x +$10 × y ≤ $100
= 4x + 10y ≤ 100..... Equation 2
Therefore, the system of linear inequalities to model the situation is written as:
x + y ≥ 5..... Equation 1
4x + 10y ≤ 100..... Equation 2
Evaluate the expression.
Answer:
40
Step-by-step explanation:
To solve this question you will need to use BEDMAS which is the order of which numbers you have to solve first. In this case you need to solve the brackets first, then the exponent, and then lastly the addition.
3^3 + 3(4 + 1/3)
= 3^3 + 3(13/3)
= 27 + 3 x 13/3
= 27 + 13
= 40

If each interior angle of a regular polygon measures 120 , how many sides does the polygon have?
Answer:
the ans is 6 sides i guess
[tex]\huge\sf{Answer :- }[/tex]
Given :- Each interior angle of regular polygon is 120°To Find :- Number of sides of the polygon Formula :-Interior angle of the polygon = [180(n - 2)]/n
where,
n = sides of the polygonSolution :-Let, The number of sides of polygon be n
By substituting values according to the formula,➯ [180(n - 2)]/n = 120°
➯ 180n - 360 = 120n
➯ 180n - 120n = 360
➯ 60n = 360
➯ n = 360/60
➠ n = 6
Hence, The regular polygon have 6 sideswhat is this equation simplified as?
