Answers

Answer:

time in years = 2.5 years

Which steps can be used to find how much popcorn Raj and his friends ate at the movies last week?

Check all that apply.
125 + 750 = 875
125 × 7 = 875
100 × 7 = 700 pieces of popcorn
100 + 750 = 850 pieces of popcorn

A square with a side of y is transformed into a rectangle by adding 10 to one side and then subtracting 10 from another. Express the new area as a polynomial

Answers

Answer: [tex]y^2-100.[/tex]

Step-by-step explanation:

if we have a square with sides 'y' units,

then, its breadth = length = y

If we add 10 to one side it will become (y+10)  (longer one) and subtract 10 from another, then it will become (y-10) (shorter one).

Area of rectangle = breadth x length

So, area of rectangle [tex]= (y+10)(y-10)[/tex]

[tex]= y^2-10^2=y^2-100\ \ \ \ \ [(a-b)(a+b)=a^2-b^2][/tex]

Hence, the new area as a polynomial = [tex]y^2-100.[/tex]

Answer:

Step-by-step explanation:

Value of function f(x) = logx at axis (1,0) is zero.

What is graph?

A graph can be defined as a pictorial representation or a diagram that represents data or values.

The graph of the logarithmic function y=logx is shown.

The domain of function f(x) = logx is the set of all positive real numbers.

1. f(x)=logx domain of the logirthimic function is (0, ∞).

2. The range is the set of all real numbers.

3. The function is continuous and one-to-one.

4. The y-axis is the asymptote of the graph.

5. The graph intersects the x-axis at (1,0). That is, the x-intercept is 1.

Value of function f(x) = logx at axis (1,0)

f(x) = 0

Thus, value of function f(x) = logx at axis (1,0) is zero.

Answers

Answer:

The answer is D.

Step-by-step explanation:

First, you have to find the area of circle using the formula :

A = π × r²

A = π × 3²

A = 9π

Given that PHU is an equilateral triangle so all sides have a degree of 60°. Next, you have to find the area of minor sector of P and U by using the formula :

A = (θ/360) × π × r²

A = (60/360) × π × 3²

A = 1.5π

Lastly, you have to subtract the area of sector from the area of circle in order to find the area of shaded region :

A = (9π × 2) - (1.5π × 2)

A = 18π - 3π

A = 15π

Describe the error made in subtracting the two rational expressions shown

Answers

Answer:

The minus sign between the two fractions was not distributed correctly.

Step-by-step explanation:

The error made in this solution of rational fractions' subtraction is that the minus sign between the two terms will change the signs of numerator of second fraction so the numerator in the answer will be 3.

The correct solution is:

[tex]\frac{1}{x-2} - \frac{1}{x+1}\\=\frac{x+1}{(x-2)(x+1)} - \frac{x-2}{(x-2)(x+1)}\\=\frac{x+1-(x-2)}{(x+1)(x-2)}\\=\frac{x+1-x+2}{(x+1)(x-2)}\\=\frac{3}{(x+1)(x-2)}[/tex]

Hence,

The error was in the last step of subtraction.

Answer:

You must subtract all terms of the numerator being subtracted out, not just the first term.

The negative 2 should have been subtracted out to get a numerator of x+1 - x+2

The simplified numerator of the difference should be 3, not –1.

O June 17, 1997
O June 1, 1997

Answers

Answer:

June 7th, 1979

Step-by-step explanation:

1979 comes before 1997, so that eliminates those. Then June comes before July. So June 7th, 1979.

June 7, 1979, is the earliest date. Option A is correct.

How to represent the date?

The recommended format for writing dates is YYYY-MM-DD, which stands for year, month, and day.

Since 1979 came before 1997, those are disregarded. June, therefore, precedes July. So, it's June 7, 1979.

The earliest date is June 7, 1979.

Hence option A is correct.

What is the polar form of Negative 2 StartRoot 3 EndRoot minus 6 i?

Answers

Answer:

4√3 [cos (2π/3) + isin(2π/3)]

Step-by-step explanation:

We are to write out the polar form of:

-2√3 - 6i

In Mathematics:

The polar form of a given complex number a + bi is given as r[cos(θ)+isin(θ)],

where r =√a²+b²and

θ = arc tan (b/a) when a is > 0

or arc tan (b/a) + π or arc tan (b/a) + 180 when a is < 0

From the above question:

-2√3 - 6i

We have that

a = −2√3 and b = −6

Hence:

r =√a²+b²

r = √(-2√3)² + (-6)²

r = √(4 × 3) + 36

r = √12 + 36

r = √48

r = √16 × 3

r = 4√3

a is < 0

Hence,

θ = arc tan (b/a) + π

θ = arc tan (-6/-2√3) + π

θ = 2π/3

Substituting 4√3 for r and 2π/3 for θ in:

r[cos(θ)+isin(θ)]

-2√3 - 6i = 4√3 [cos (2π/3) + isin(2π/3)]

So tell me. after converting the 1/4 to a decimal what do you get?  .25 right or just to not confuse you 0.25, so then after converting it to a decimal bring down that whole number which is 2.
