The slope of the line that contains the given points A(0,6), B(4,0) is -3/2.

It is given in the question that the line contains the points A(0,6) and B(4,0).

We know that:-

The formula to find the slope of a line that contains points (a,b) and (c,d) is given by:-

m = (d-b)/(c-a)

Here, we have

m = slope of the line

(a,b) = (0,6)

(c,d) = (4,0)

Hence, putting the values of (a,b) and (c,d) , we get

9:28 would be the time the movie ends

Answer:

9:28

Step-by-step explanation:

First, add an hour to 7:45. Then, find how much time there is until you reach the next hour. After that, take the remaining time and add it on. 7:45 plus one hour is 8:45. There is fifteen minutes until the next hour, so subtract that from the forty three minutes. Add that fifteen minutes on and you are at nine o'clock. There is twenty eight minutes left. Add it in to nine o'clock. You now have the time the movie will end

Considering that the surface area and the volume of the cylinders are equal, the surface areas are given as follows:

14. 108π ft².

15. 250π ft².

For a cylinder of radius r and height h, the surface area is given by:

S = 2πr(h + r).

The volume is given by:

V = πr²h.

For item 14, the parameters are given as follows:

r = 6 ft, h = x ft.

Hence we solve for x equaling the surface area and the volume as follows:

V = S

36πx = 12π(x + 6)

3x = x + 6

2x = 6.

x = 3.

Hence the surface area is:

S = 12π(3 + 6) = 108π ft².

For item 15, the parameters are given as follows:

r = 10 ft, h = x ft.

Hence we solve for x equaling the surface area and the volume as follows:

V = S

100πx = 20π(x + 10)

5x = x + 10

4x = 10.

x = 2.5.

Hence the surface area is:

S = 20π(2.5 + 10) = 250π ft².

The correct option is (B) 9/13.

The probability that it will not snow on Tuesday is 9/13.

The ratio of the quantity of favorable outputs to the overall number of possibilities of an event is defined as probability.

The number of favorable results for an experiment with 'n' outcomes is denoted by x.

The following formula is used to determine the probability of an event.

Probability(Event) = Favorable Outcomes/Total Outcomes = x/n.

Some properties of the probability are mentioned below-

Now, for the stated question;

The probability that it will snow on Tuesday is 4/13.

Use property 1;

Then, the probability that it will not snow on Tuesday is;

= 1 - 4/13

= (13 - 4)/13

= 9/13

Therefore, the probability that it will not snow on Tuesday is 9/13.

The inequality given by 4x - 2 > 1/2 has the solution x > 5/8 or (5/8 , +∞).

Inequality refers to the relationship between two non-equal expressions. It can be denoted by > for greater than, < for less than, >/= for greater than and equal to, and </= for less than and equal to.

To solve an inequality is to find the values of x such that when we substitute that number for x we have a true statement.

Given the inequality 4x - 2 > 1/2, add 2 to both sides.

4x - 2 + 2 > 1/2 + 2

4x > 5/2

Multiply both sides by 1/4.

1/4(4x) > 1/4(5/2)

x > 5/8

To check, let x = 3/4

x = 3/4 ≥ 5/8

Substitute this value to the inequality.

4x - 2 > 1/2

4(3/4) - 2 > 1/2

3 - 2 > 1/2

1 > 1/2

Answer:

False

Step-by-step explanation:

Let's just analyze it.

x=2 if and only if |x|=2

That can be rewritten as:

if x = 2 then |x| = 2

AND

if |x| = 2 then x = 2

Let's solve each one separately:

we have x = 2

we can simply get |x| by removing the sign, if any. There is none, so |x| = 2.

The first part checks out.

we have |x| = 2

As with absolute values, this means that either x = 2 or x = -2

So we know from |x| that x is either 2 or -2, but the logical statement said "if |x| = 2 then x = 2", which is too specific - it forgets about -2.

The second part is false.

Overall, we now know that "X=2 if and only if |x| = 2" is false because x = -2 is a counterexample. We get: "False if and only if True" which itself is false.

Step-by-step explanation:

since 71 percent of the rock is remaining, the half life hasn't been reached yet. Hence, we know uranium isn't 4.5 billion years old yet. However, every-time 4.5 billions years pass, the rock get smaller by 2 times(a scale factor of 1/2). Hence, you can express that in a log equation:

[tex]\log_{2}(100/(percent of rock remaining))=[/tex] Fraction of 4.5 billions years of time passed

[tex]\log_{2}(100/50)=1[/tex]   ==> 100% of 4.5 billion years passed. When 50% of rock remains, 4.5 billion years have passed.

[tex]\log_{2}(100/100)[/tex] =

[tex]\log_{2}(1)=0[/tex]   ==> 0% of 4.5 billion years passed. When the rock hasn't decayed at all yet, that means that it is 0 years old.

When two straight lines or rays intersect at a shared endpoint, an angle is generated. The measure of ∠3 is 31°.

When two straight lines or rays intersect at a shared endpoint, an angle is generated. An angle's vertex is the common point of contact. Angle is derived from the Latin word angulus, which means "corner."

Given that ∠2 and ∠3 are supplementary angles. Therefore, the sum of the two angles will be 180°. Thus, we can write the sum of the two angles as,

∠2 + ∠3 = 180°

Also, it is mentioned in the question that the measure of ∠2 is 149°. Therefore, substitute the value of ∠2 in the above equation.

149° + ∠3 = 180°

∠3 = 180° - 149°

∠3 = 31°

Hence, the measure of ∠3 is 31°.

Given,

Points (x, y) = (-1, 5)

Parallel to y = 4x - 5

Now,

Recall that a parallel line to the one given has to have the same slope. The slope of the line given is "4" (the coefficient that accompanies "x").

Therefore the equation of a parallel line has to be of the form:

y = 4x - b

5 = 4(-1) - b

You seem to want 10^exponent, where exponent is an even single digit, not zero.

We choose exponent = 2, so your expression is ...

10^2

__

There are several versions of expanded form. One uses exponents. In that form, the expression above is the expanded form.

Another uses multipliers of 1, 10, 100, 1000, and so on. In that form, the expression expands as ...

10^2 = 1×100

Another expanded form uses individual digits of the expanded form with others set to zero

10^2 = 100

The standard form is ...

10^2 = 100.

_____

We suppose your exponential expression might have another multiplier, such as 2.98:

exponential expression: 2.98×10^2

standard form: 298

expanded form 1: 2×10^2 + 9×10^1 +8×10^0
