Two angles are complementary (the sum of the two angles is 90°). The sum of the first
angle plus twice the second angle is 128°. Find the measures of the angles.
Answer:
A = 52º AND B=38º
Step-by-step explanation:
Let's call A and B the two angles.
First condition: A + B = 90º
Second cond: A + 2B = 128º
Subtract the first condition to the second: B = 38º
Replace the value of B in any of the 2 conditions; e.g. in the first.
A + 38º = 90º
A = 90º - 38º = 52º

Write the following expression in terms of logs of x,y and z
Show steps
We can write the log expression in terms of the log of x, y, and z as expression 1/2(logx+2logy-8logz).
What is a logarithm?It is another way to represent the power of numbers and we say that 'b' is the logarithm of 'c' with base 'a' if and only if 'a' to the power 'b' equals 'c'.
[tex]\rm a^b = c\\\\log_ac = b[/tex]
We have an expression in logarithm:
[tex]=\rm log\sqrt{\frac{xy^2}{Z^8} }\\\\=log(\frac{xy^2}{Z^8})^{\frac{1}{2} }\\\\=\frac{1}{2}log(\frac{xy^2}{Z^8})[/tex] [tex](\rm loga^b = (b)log(a))[/tex]
[tex]\rm\frac{1}{2} (log(xy^2)-logz^8)[/tex] [tex](\rm log(\frac{a}{b} )= loga - logb)[/tex]
[tex]\rm\frac{1}{2} (log(x)+log(y^2)-logz^8)[/tex] [tex](\rm logab = loga+logb)[/tex]
[tex]\rm\frac{1}{2} (log(x)+2log(y)-8logz)[/tex]
Thus, we can write the log expression in terms of the log of x, y, and z as 1/2(logx+2logy-8logz).

It takes 4 people 6 days to build a wall. How long would it take 6 people to build the same wall?
Answer:
1 day
Step-by-step explanation:
4=6
2=3
2*3=6
so 3/3=1
It would take 6 people to build the wall 1 day
It takes 4 days to build the same wall with 6 people based on the given ratio.
What are the ratio and proportion?The ratio is the division of the two numbers.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given,
It takes 4 people 6 days to build a wall.
The number of people days taken = 4 x 6 = 24 people takes
This means if one person wants to build them it takes 24 days.
For 6 people the time taken will be 24/6 = 4 days.
Hence "It takes 4 days to build the same wall with 6 people based on the given ratio".

Amelia should randomly choose people only in their block.
Amelia should ask people what part of the neighborhood they live in.
Amelia should ask people their age.
What is representative sample?A representative sample are data collected from small group of individual which can be use to represent a large population of people so as to reach a conclusion.
Most researcher tend to make use of representative sample when they want to draw a conclusion as it save time and reduce the stress of having to carryout survey on a larger population.

Find the surface area of the cone in terms of π.
Answer:
161 × pi cm²
Step-by-step explanation:
we just had the question about the lateral surface area (which is the area of the "mantle" of the cone from the round bottom to the pointy top).
the whole surface area of a cone is then simply the lateral surface area plus the ground area, which is a circle.
so, we have
A = pi×r×sh + pi×r²
r = radius (remember, this is half of the diameter)
sh = slant height (the length of the "mantle" straight up from the ground to the top)
so, the surface area of our cone here is
A = pi×(14/2)×16 + pi×(14/2)² = pi×7×16 + pi×7² =
= 112×pi + 49×pi = 161 × pi cm²

Domain of this function is R or (-∞,∞)
Cuz this function of definable in each and every real number
is (x-4) a factor of f(x)=x^3-2x^2+5x+1 explain your reasoning
Answer:
No.
Step-by-step explanation:
It's simpler than you might expect.
If [tex](x - 4)[/tex] is a factor, then it means that it the function [tex]f(x) = x^3 - 2x^2 + 5x + 1[/tex] can have [tex](x - 4)[/tex] factorised out.
This means that we can say [tex](x - 4) = 0[/tex]
Therefore [tex]x = 4[/tex]
If we put [tex]x = 4[/tex] into the equation:
[tex]f(4) = (4)^3 - 2(4)^2 + 5(4) + 1\\= 64 - 32 + 20 + 1\\= 53[/tex]
We didn't get 0, therefore it isn't a factor!

Step-by-step explanation:
A triangle is always determined by the names of its angles. If, for any reason, you wanted to label it by its side names(which I don't even think you can do but assuming you wanted to), you dont even have the names for all three sides here. So, it can only be d. A, X, and T are the three angle names for this triangle, so this is triangle ATX or AXT.
Answer:
ATX (option d)
Step-by-step explanation:
Sides of any polygon are called as vertices.
Vertices of the triangle or endpoints of the sides of the polygon are A, T and X.
Triangles can also be classified by their angles. In an acute triangle all three angles are acute.
