If you are tossing a six-sided die, what is the probability of getting either a 1 or a 2 on your first toss and a 1 or a 2 on your second toss?.
A six sided dice is tossed twice. The probability of getting either a 1 or a 2 on your first toss and a 1 or a 2 on your second toss is 1/9 .
A dice has six faces or sides and it is throws twice . When a dice is toss first time,
Total possible outcomes on toss = 6 ={ 1,2,3,4,5,6}
In our first toss we want to get 1 or 2
So, favourable outcomes of getting 1 or 2 = 2
Probability of getting 1 or 2 on first toss= favourable cases /total outcomes = 2/6 = 1/3
For second toss, we want to get a1 or a2 again.
Total possible outcomes = 6
Probability of getting a1 or a2 on second toss= 2/6= 1/3
Now, Multiply these probsbilites togethers and chance of getting 1 or 2 on first and second which is 1/3× 1/3 = 1/9
Hence , probability of getting either a 1 or a 2 on your first toss and a 1 or a 2 on your second toss is 1/9.

A projectile is fired vertically upward, and its height s(t) in feet after t seconds is given by the function defined by
s(t) = -16t² + 800t + 600.
To find out
(a) From what height was the projectile fired
Given height functions: s(t) = -16t² + 800t + 600
Now,
[tex]s^{'}(t)[/tex] - -32t+800
(b) Now, to find the time it will attain maximum height,
[tex]s^{'}(t)[/tex] = 0
-32t = -800

Find the 8th term of the geometric sequence 10, -20, 40, ...
Answer:
a₈ = - 1280
Step-by-step explanation:
the nth term of a geometric sequence is
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
here a₁ = 10 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{-20}{10}[/tex] = - 2 , then
a₈ = 10 [tex](-2)^{7}[/tex] = 10 × - 128 = - 1280
The 8th term of geometric sequence is -1280
Step of calculate geometric sequence
This is a geometric sequence. The geometric number sequence is characterized by the presence of a ratio (the ratio between the next term and the previous term). The next term is the product of the previous term with the ratio. Another sequence called arithmetic sequence is characterized by the presence of difference (the difference between the next term and the previous term).
10, -20, 40, ...
We will first analyze the things that can be found in the three numbers in the sequence. The thing to look for is the first term (a) and also the ratio (r). The first term can also be written as U1, where the 2nd term is U2, and the n-th term is Un.
[tex]a = 10[/tex]
[tex]r=\frac{U2}{U1}[/tex]
[tex]r=\frac{-20}{10}[/tex]
[tex]r=2[/tex]
When the first term (U1) and ratio (r) have been obtained, then we can find the 8th term by substitute it in the formula.
[tex]Un=ar^{n-1}[/tex]
With that formula, let's find the 8th term.
[tex]U8=10(-2)^{8-1}[/tex]

Answer:
about 21.3 cm²
Step-by-step explanation:
Given a triangle with three sides 6 cm, 8 cm, and 12 cm, and smallest angle 26.4°, you want the area.
Area using sine formulaA = 1/2ab·sin(C)
A = 1/2(12 cm)(8 cm)·sin(26.4°) ≈ 21.34 . . . . square units
Area using Heron's formulaThe semiperimeter is ...
s = (6 +8 +12)/2 = 13
The area is ...
A = √(s(s -a)(s -b)(s -c))
A = √(13·(13 -12)(13 -8)(13 -6)) = √(13·1·5·7) = √455
A ≈ 21.33 . . . . square centimeters
The area of the triangle is about 21.3 cm².
__
Additional comment
The problem with over specifying the dimensions of a geometry problem is that it is often difficult to make them consistent. Here, the area values agree to three significant figures. That is about all we can expect, given the angle precision is 3 significant figures.
Your answer depends on the set of dimensions you choose to use. It will be different yet if you use the Law of Sines to find angle A or B for the Sine Formula, especially if you round the angle value to tenths.

A telecommunications company will be laying new fiber optic cables underground. One cable will be perpendicular to the road shown, passing through the point ( 7, 2 . At what point will the cable pass through the road?
The point at which this cable would pass through the road shown is at the y-intercept of (0, -17/2).
How to determine an equation and the point on this perpendicular line?Mathematically, the slope of a straight line can be calculated by using this formula;
Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Slope, m = (y₂ - y₁)/(x₂ - x₁)
By critically observing the road shown in the graph above, the points on the line include the following:
Points (x, y) = (0, -2)
Points (x, y) = (-3, 0)
Substituting the given points into the formula, we have;
Slope, m = (0 + 2)/(-3 - 0)
Slope, m = 2/-3
Slope, m = -2/3.
In Mathematics, a condition that must be met for two lines to be perpendicular is given by:
m₁ × m₂ = -1
-2/3 × m₂ = -1
-2m₂ = -3
m₂ = 3/2
At point (7, 2), a linear equation for the line can be calculated by using the point-slope form:
y - y₁ = m(x - x₁)
Where:
m represents the slope.x and y represent the points.c represents the y-intercept.Substituting the given points into the formula, we have;
y - 2 = 3/2(x - 7)
y - 2 = 3x/2 - 21/2
y = 3x/2 - 21/2 + 2

Step-by-step explanation:
Given the equation
[tex]x-\frac{2}{5}=\frac{2}{3}-3x-\frac{2}{6}[/tex]
Lets solve for x.
Simplify the right side of the equation.
Cancel the common factor of 2 and 6 .
Factor 2 out of 2 .
[tex]x-\frac{2}{5}=\frac{2}{3}-3x-\frac{2(1)}{2(3)}[/tex]
[tex]x-\frac{2}{5}=\frac{2}{3}-3x-\frac{1}{3}[/tex]
Combine the numerators over the common denominator.
[tex]x-\frac{2}{5}=-3x-\frac{2-1}{3}[/tex]
[tex]x-\frac{2}{5}=-3x-\frac{1}{3}[/tex]
Move all terms containing x to the left side of the equation.
Add [tex]3x[/tex] to both sides of the equation.
[tex]x-\frac{2}{5}+3x=\frac{1}{3}[/tex]
Add [tex]x[/tex] and [tex]3x[/tex].
[tex]4x-\frac{2}{5}=\frac{1}{3}[/tex]
Move all terms not containing x to the right side of the equation.
Add [tex]\frac{2}{5}[/tex] to both sides of the equation.
[tex]4x=\frac{1}{3}+\frac{2}{5}[/tex]
To write [tex]\frac{1}{3}[/tex] as a fraction with a common denominator, multiply by [tex]\frac{5}{5}[/tex] .

Solving the inequality -6.6 < 1.7 + u for u, the solution is simplified as: u > -8.3 or -8.3 < u.
What is an Inequality?In maths, an inequality is defined as a statement that is used to compare two quantities that are unequal. For example, we can state that 5 is greater than 3 + 1, or 5x is less than 4x + 3x. We can equally state that a given value of a variable can be equal to or greater than a number, and so on.
Basically, we are comparing two unequal quantities when we state inequalities.
Given the inequality, -6.6 < 1.7 + u, we are asked to solve the inequality for u. That is, we need to find the possible value that u represents in the inequality or that would make the inequality true.
Therefore:

The total flying time for the round trip if there was no wind would be 2 hours 24 minutes. The result is obtained by using the elimination method.
What is elimination method?The elimination method is a method for solving system of linear equations where we eliminate one variable so that we can get an equation in one variable. In doing that, we can either add or subtract the equations.
Given the case that an airplane takes 1 hour 30 minutes to fly 600 km against the wind. It takes only 1 hour in the return trip.
What would be the total flying time for the round trip if there was no wind?
Let's say:
v = the speed of the airplanew = the speed of the windWhen the airplane leaves,
v - w = 600 km / 1.5 hour
v - w = 400 kph ... (equation 1)
When the airplane returns,
v + w = 600 km / 1 hour
v + w = 600 kph ... (equation 2)
We eliminate the equation 2 and 1 to get the speed of the airplane.
v - w = 400 kph
v + w = 600 kph +
2v = 1000 kph
v = 1000 ÷ 2
v = 500 kph
For the round trip, the airplane would fly 600 × 2 = 1200 km.
The total flying time if there was no wind would be
t = s/v
t = 1200/500
t = 2.4 hour
t = 2 hours 24 minutes
Hence, the total flying time for the round trip if there was no wind is 2 hours 24 minutes.

The expressions that represent the total weekly wages of Rita is 11r + 32 and of Tina is 11t.
We are given;
Rita and Tina each make $11 an hour working as cashiers at a supermarket.
Last week, Rita worked r hours while Tina worked t hours.
Rita also worked overtime hours during the week, for which she was paid an extra $32 flat wage.
We need to find the expressions that represent the total weekly wages of both Rita and Tina.
Let us form an algebraic expression for both one by one;
For Rita:
Number of hours Rita worked for = r
Cost per hour = $ 11
The amount for overtime Rita earned = $32
So, the equation expressing the total weekly wage for Rita = 11r + 32.
For Tina :
Number of hours Tina worked for = t
Cost per hour = $ 11
So, the equation expressing the total weekly wage for Tina = 11t.
Thus, the expressions that represent the total weekly wages of Rita is 11r + 32 and of Tina is 11t.
