What is the approximate solution to the equation 2^t=22?
0.6712
1.0414
4.4594
11.0000
Answer:
[tex]t=4.4594[/tex]
Step-by-step explanation:
We can take the log 2 of both sides to get [tex]t=\log_2(22)[/tex].
We know that [tex]2^4<22<2^5[/tex], so [tex]4<t<5[/tex].
So, the solution is [tex]\boxed{t=4.4594}[/tex] because it's the only answer that works.
Which number is larger, 2x10^-3 or 3x10^-2? Explain.
Answer:
3×10'-2 is larger
Step-by-step explanation:
2×10'-3=0.002
3×10'-2=0.03
Answer:
3x10^-2 is larger
Step-by-step explanation:
2x10^-3 = 0.002
beause 10^-3 = decimal place three place to the left
3x10^-2 = 0.03
beause 10^-2 = decimal place two place to the left
A new car is purchased for 20800 dollars. The value of the car depreciates at 10.75% per year. What will the value of the car be, to the nearest cent, after 13 years.
Answer:
Step-by-step explanation: Exponential depreciation formula :-
y = A(1 - r)^t, where y is the value of good after t years , r is rate of depreciation and A is the initial value.
Given : A= $20800 ; r=10.75%=0.1075
The equation models this situation:
Then, the value of car after t=13 years :-
Hence, the value of car after 13 years = $4742.10

A kindergarten teacher bought $21 worth of stickers and cardstock for his class. The stickers cost $1.50 a sheet and the cardstock cost $3.50 per pack. The equation LaTeX: 1.5s+3.5c=21 represents the relationship between sheets of stickers, LaTeX: s, packs of cardstocks, LaTeX: c, and the dollar amount a kindergarten teacher spent on these supplies.
Answer:
Done
Step-by-step explanation:
Teacher bought $21 worth of stickers and cardstock for his class.
Cost of stickers = $1.50 per sheet
Cost of 's' sheets = $1.5s
Cost of cardstock = $3.50 per pack
Cost of 'c' packs = $3.5c
Equation representing the relationship between sheet of stickers and packs of cardstocks will be,
1.5s + 3.5c = 21
3.5c = -1.5s + 21
1).
y-intercept of the line → (0, 6)
x-intercept of the line → (14, 0)
Therefore, equation of the line represents the line on the graph.
2). Vertical intercept (0, 6) represents that he can purchase maximum 6 packs of cardstock with $21.
Similarly, horizontal intercept (14, 0) represents that he can purchase maximum 14 sheets of stickers with $21.
Compare the two numbers by choosing <, >or =
Answer:
In order to compare the fractions we can first obtain the LCM of the denominators of the two fractions and that is to say
= LCM of 5 and 3 which is 15
= [tex]\frac{2}{5} * 15[/tex]
=6
and also:
= [tex]\frac{1}{3} * 15[/tex]
=5
So in conclusion the numbers 6 and 5 will determine the sign to be used and since 6 is for [tex]\frac{2}{5}[/tex] and 5 is for [tex]\frac{1}{3}[/tex] and numerically 6 is greater than 5 therefore:
[tex]\frac{2}{5} > \frac{1}{3}[/tex]
Find two consecutive even integers such
that 5 times the smaller integer is 44 more
than 2 times the larger integer.
Step-by-step explanation:
5n = 44 + 2(n+2)
5n = 44 +2n+4
5n-2n = 48
3n = 48
n = 16
the integers are : 16 and 18

write the log equation as an exponential equation. you do not need to solve for x.
Answer:
[tex]5^{1/6} =2x[/tex]
Step-by-step explanation:
Log and exponential forms are inverses. Additionally, the information from one can be used to write in it another form. In a log equation, there are three parts. The formula is [tex]log_{b}(x)=y[/tex]. The formula for exponential equations is [tex]b^y=x[/tex]. This means to find this equation in exponential form write 5 as the base, 1/6 as the power, and 2x as the other side of the equation. This looks like, [tex]5^{1/6} =2x[/tex].

What is the value of x in the equation 1.5(x + 4) – 3 = 4.5(x – 2)?
Step-by-step explanation:
1.5x + 6-3= 4.5x- 2
1.5x+3=4.5x-2
we transposed
4.5x-1.5x= 3+2
3x= 5
we divide both sides by 3
3x/3= 5/3
x= 5/3

Answer:
- 5 [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
- 3 [tex]\frac{1}{2}[/tex] - 1 [tex]\frac{5}{6}[/tex] ( change to improper fractions )
= - [tex]\frac{7}{2}[/tex] - [tex]\frac{11}{6}[/tex] ( multiply numerator/denominator of first fraction by 3 )
= - [tex]\frac{7(3)}{2(3)}[/tex] - [tex]\frac{11}{6}[/tex]
= - [tex]\frac{21}{6}[/tex] - [tex]\frac{11}{6}[/tex]
= [tex]\frac{-21-11}{6}[/tex]
= [tex]\frac{-32}{6}[/tex]
= - [tex]\frac{32}{6}[/tex]
= - 5 [tex]\frac{2}{6}[/tex]
= - 5 [tex]\frac{1}{3}[/tex]

What would be the range of possible whole number values (x) for a 3rd side of the triangle with two sides of 5 in. and 8 in.?
& Name one possible value for a third side?
Correct Answer Only
Answer:
Range of the third side of a triangle
Step-by-step explanation:
Any one side of a triangle must be shorter than the sum of the other two sides. Therefore, the third side length x must be between 5 and 35, not including those endpoints: 5 < x < 35. All whole numbers satisfying this range would form a triangle.
20 is a possible value for a third side
what is the difference between a categorical and continuous variable?
Answer:
In a categorical variable, the value is limited and usually based on a particular finite group. For example, a categorical variable can be countries, year, gender, occupation. A continuous variable, however, can take any values, from integer to decimal.

I hate sails math- like what is the point of it? -_-
Answer:
The only math I see having a point is basic math like addition subtraction multiplication and division, unless you are going for a job that requires ALOT of harder math.
Solve the math problem
Answer:
x = 52°Step-by-step explanation:
The 124° angle is exterior to the given triangle.
The exterior angle is the sum of non- adjacent interior angles:
x + 72 = 124x = 124 - 72x = 52°Sum.of two interiors=Exterior
x+72=124x=124-72x=52°suppose that p is the probability that a randomly selected person is left handed. The value (1-p) is the probability that the person is not left-handed. In the sample of 100 people, the function V(p)= 1000 p(1-p) represents the variance of the number of left-handed people in a group of 100.
a) What value of p maximizes the variance?
b) What is the maximum variance?
Answer:
a) 1/2
b) 250
Step-by-step explanation:
The start of the question doesn't matter entirely, although is interesting to read. What we are trying to do is find the value for [tex]p[/tex] such that [tex]1000p(1-p)[/tex] is maximized. Once we have that [tex]p[/tex], we can easily find the answer to part b.
Finding the value that maximizes [tex]1000p(1-p)[/tex] is the same as finding the value that maximizes [tex]p(1-p)[/tex], just on a smaller scale. So, we really want to maximize [tex]p(1-p)[/tex]. To do this, we will do a trick called completing the square.
[tex]p(1-p)=p-p^2=-p^2+p=-(p^2-p)=-(p^2-p+1/4)-(-1/4)=-(p-1/2)^2+1/4[/tex].
Because there is a negative sign in front of the big squared term, combined with the fact that a square is always positive, means we need to find the value of [tex]p[/tex] such that the inner part of the square term is equal to [tex]0[/tex].
[tex]p-1/2=0\\p=1/2[/tex].
So, the answer to part a is [tex]\boxed{1/2}[/tex].
We can then plug [tex]1/2[/tex] into the equation for p to find the answer to part b.
[tex]1000(1/2)(1-1/2)=1000(1/2)(1/2)=1000*1/4=250[/tex].
So, the answer to part b is [tex]\boxed{250}[/tex].
And we're done!
