The distance, D, travelled by a particle is directly proportional to the square of the time, t, taken. When t = 40, D = 30. find a formula for D in terms of t. Calculate the value of D when t = 64​

Answer:

I think it's the third choice because line segments are congruent and not equal. Line segments also have little lines on top of the letters.

Step-by-step explanation:

======================================================

Explanation:

AB = BC refers to the fact that expressions 2x+7 and 4x-3 are equivalent. They represent numbers when we replace x with some number. So after doing that replacement, we have something in the form number = number.

So this is why choice A is one of the answers.

[tex]\overline{AB} \cong \overline{BC}[/tex] says "segment AB is congruent to segment BC". The horizontal lines over the lettering indicates we have a segment. The equal sign with a squiggle over top is the congruence symbol. In geometry, we say two items are congruent if they are the same. You can think of making a clone of the object and then sliding it over. In this case, we've cloned segment AB to form segment BC.

This is why choice C is the other answer.

--------------

Choices B and D are close, but not quite correct. Choice B is missing the segment markers. Choice D is missing the congruence symbol. Congruence and equality are very similar ideas, so often they get mixed up.

Answer:

Wednesday

Step-by-step explanation:

The given daily temperature in New York from Monday to Thursday:

Monday: [tex]1^{\circ}C[/tex]

Tuesday: [tex]2^{\circ}C[/tex]

Wednesday: [tex]5^{\circ}C[/tex]

Thursday: [tex]-1^{\circ}C[/tex]

Now, among the given temperatures,[tex]1^{\circ}C, 2^{\circ}C, 5^{\circ}C,[/tex] and [tex]-1^{\circ}C,[/tex] the highest temperature is [tex]5^{\circ}C[/tex].

As the day having the highest temperature is the warmest day which is Wednesday.

So, on Wednesday the temperature was warmest.

Step-by-step explanation:

Answer: No, 1.888 is a rational number. In mathematics, the irrational numbers are all the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers. When the ratio of lengths of two line segments is an irrational number, the line segments are also described as being incommensurable, meaning that they share no "measure" in common, that is, there is no length ("the measure"), no matter how short, that could be used to express the lengths of both of the two given segments as integer multiples of itself.

£432.75 to 2 significant figure, is 4.3275*10²  

The term significant figures refers to the number of important single digits (0 through 9 inclusive) in the coefficient of an expression in scientific notation.

Given a term £432.75

Rounding £432.75 to 2 significant figure, we get,

432.75 = 4.3275*10²

Hence, 432.75 to 2 significant figure, is 4.3275*10²

Final Answer.

Answer:

7,065 meters.

Step-by-step explanation:

The problem is asking for "the difference" between two points. "The difference" means you're subtracting. The second point says it is below sea level, though. That makes it a negative number. Thus:

[tex]6960-(-105)=x[/tex]

When subtracting by a negative number, think of it as addition, since the negative cancels out the subtraction sign. This turns it into:

[tex]6960+105=7065[/tex]

There is a 7,065 meter difference between the two points.

Step-by-step explanation:

1.05 should be it

Step-by-step explanation:

In a recursive formula, each term of the sequence is found by using the previous term.  In this case, the sequence is geometric because we are multiplying each term by the same constant, called a common ratio.

To find this common ratio, we find the percent of change between terms.  We do this by using the formula

% change = (amount of change)/(original amount)

The amount of change between the first two terms is 105-100 = 5.  This makes the percent change

5/100 = 0.05

The amount of change between the second two terms is 110.25-105 = 5.25.  This makes the percent change

5.25/105 = 0.05

However, the common ratio in the sequence is not 0.05.  This is because multiplying by this decimal would make the terms decrease instead of increasing.  In this case, we are taking 100% of the number and adding an extra 5% (0.05 = 5%); this makes our common ratio 105% = 1.05.

This gives us the recursive formula

Step-by-step explanation:

Step-by-step explanation:

[tex]\bf{2( x + 10) =4( 2x - 1)}[/tex]

We need the value of x. So, we will break the brackets first.

[tex]\bf{2( x + 10) =4( 2x - 1)}[/tex]

[tex]\bf{2x + 20 = 8x - 4}[/tex] [ Distributive Property]

[tex]\bf{2x -8x = -20 - 4}[/tex] [ Brought x to one side and signs interchange]

[tex]\bf{-6x = -24}[/tex]

[tex]\bf{x = \dfrac{24}{6}}[/tex]

[tex]\bf{x = 4}[/tex]
