Answer:
90 cm is submerged (depth of water)
Step-by-step explanation:
Refer to diagram attached.
Let
x = total length of the lotus stem
16 = exposed part of stem
56 = horizontal displacement.
Hence
depth of water = x-16
Using the Pythagorean theorem,
(x-16)^2 + 56^2 = x^2
Expand
x^2 -32x + 256 +3136 = x^2
Simplify
3392 = 32x
x = 3392/32 = 106
Depth of water = x-16 = 106 - 16 = 90 cm

based on the function h(t), what will be the account value five years after the account is opened?
Answer:
Option B
Step-by-step explanation:
f(t) = 5000
g(t) = 250t
h(t) = f(t) + g(t) = 5000 + 250t
After 5 years, the amount of money in the account is:
h(t = 5) = 5000 + 250(5) = 5000 + 1250 = 6250$

Step-by-step explanation:
A school is selling tickets to a drama performance. On the first day of ticket sales the school sold 3 adult tickets and 1 child ticket for a total of $38. On the second day, the school sold 3 adult tickets and 2 child tickets for a total of $52.
Which of the following system of linear equations could model this situation?
Answer:
System of linear equations
[tex]\left\{\begin{matrix} 3a+c=38 \\\\ 3a+2c=52 \end{matrix}\right.[/tex]
a: adult ticket price and c: child ticket price
Step-by-step explanation:
This system of equations can be used to find the price of the adult and child tickets.
We have two equations (one for each day) and two unknowns (adult ticket price and child ticket price).
Let a: adult ticket price and c: child ticket price,
we have for the first day that 3 adult tickets and 1 child ticket adds $38:
[tex]3a+1c=38[/tex]
and for the second day we have that 2 adult tickets and 2 child tickets adds $52:
[tex]3a+2c=52[/tex]
If we write this as a system of equations, we have:
[tex]\left\{\begin{matrix} 3a+c=38 \\\\ 3a+2c=52 \end{matrix}\right.[/tex]
In a school auditorium, the number of chairs in a row is the same as the number of rows of chairs. There are 7033 students in the school. If we know that less than 31 chairs were empty, how many chairs were empty after all the students sat down?
Same number of rows to chairs in a row would form a square.
Use the total number of students as the area
Find the number or rows by taking the square root of student:
The square root of 7033 is 83.86
Round up to 84
Total seats would be rows x seats per row:
84 x 84 = 7,056 total seats
7056 seats - 7033 students = 23 empty seats
Find the length of side a
Answer:
a = 8.
Step-by-step explanation:
a^2 + b^2 = c^2
b = 6; c = 10
a^2 + 6^2 = 10^2
a^2 + 36 = 100
a^2 = 64
a = plus or minus 8
Since side lengths can't be negative, a = 8.

find m
4x-3y=17
-78 + my = 2
Answer:
Step-by-step explanation:
Given: 4X-3Y=17
so, 4x-17 = 3Y
=> Y = (4X-17)/3
Substituting the value in second equation, we get,
=> -78 + m(4x-17)/3 = 2
=>2+78 = m(4x-17)/3
=> 80*3 = m(4x-17)
=>m= 240/(4x-17)

Find the measures of two angles, one positive and one negative, that are coterminal with pi divided by ten . (2 points) twenty-one pi divided by ten ; negative pi divided by ten eleven pi divided by ten ; negative nine divided by ten twenty-one pi div
Answer:
The two angles coterminal with π/10 are 21π/10 and -19π/10
Step-by-step explanation:
To find a two angles that are coterminal with π/10, we add and subtract 360°(that is 2π) from π/10.
So, the first angle coterminal with π/10 is
A = π/10 + 2π
taking the L.C.M which is 10, we have
A = (π + 20π)/10
A = 21π/10
The second angle coterminal with π/10 is
B = π/10 - 2π
taking the L.C.M which is 10, we have
B = (π - 20π)/10
B = -19π/10
So the two angles coterminal with π/10 are 21π/10 and -19π/10

Answer:
Third option is correct.
Step-by-step explanation:
Take a closer look at the box plot given in the question. The range of the values represented in the box plot is starts from where the whiskers begins from our left, and where the whiskers to our right ends. The range of values of the points awarded ranges from 0 - 100, as represented on the box plox. Also,the median is indicated by the vertical line that divides the rectangular box into two. The median point = 70.
Now, examine all the dot plots given as options. The dot plot that has a range of 0 - 100, and a median of 70, is the dot plot that best represents the box plot.
Thus, the third option among the answer choices given would be out answer. The third option shows a dot plot with range of values of points from 0 - 100, and also a median of 70 points.
If f(x)= x-6 and g(x)=x2(x+3), find g(x) x f(x)
Answer:
x^4 -3x^3 - 18x^2
Step-by-step explanation:
f(x)= x-6
g(x)=x^2(x+3),
g(x) * f(x) = (x-6) * x^2(x+3)
= x^2 ( x-6) ( x+3)
FOIL
= x^2 ( x^2 +3x-6x-18)
Combine like terms
= x^2 ( x^2 -3x-18)
Distribute
= x^4 -3x^3 - 18x^2
Answer:
x⁴ - 3x³ - 18x²
Step-by-step explanation:
g(x) × f(x)
(x²(x + 3)) × (x - 6)
Expand brackets.
(x³ + 3x²)(x - 6)
x³(x - 6) + 3x²(x - 6)
x⁴ - 6x³ + 3x³ - 18x²
Combine like terms.

Multiply. (5x+7)^2 :)
Answer:
The answer is B.
Step-by-step explanation:
You can expand it in a simplier way using :
[tex] {(a + b)}^{2} = {a}^{2} + 2ab + {b}^{2} [/tex]
So for this question :
[tex] {(5x + 7)}^{2} \\ = {(5x)}^{2} + 2(5x)(7) + {(7)}^{2} \\ = 25 {x}^{2} + 70x + 49[/tex]
Answer:
B. 25x^2+70x+49
Step-by-step explanation:
To multiply we can use a method called FOIL. In this method, we multiply the first terms of each binomial, then the outer terms (first and last), then the inner terms (2nd and 3rd), and finally the last terms (2nd and last). The two binomials in this case are (5x+7)(5x+7).
So this means we first multiply 5x*5x, then 5x*7, then 7*5x, and finally 7*7. Multiplying these out we get 25x^2 + 35x + 35x +49. Finally, combining like terms we get 25x^2+70x+49, which is our answer.

What two numbers multiply to 1/4 and add to -1?

Step-by-step explanation:
Two or more expressions with an Equal sign is called as Equation. Two numbers are x =-1/2 and y=-1/2 whose product is 1/4 and which add to -1.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
We need to find two numbers whose product is 1/4 and add to -1.
Let the two numbers are x and y.
By given,
Two numbers multiply to 1/4
xy=1/4
Two numbers add to -1
x+y=-1
Let x=-y-1
Substitute in equation 1.
(-y-1)y=1/4
-y²-y-1/4=0
Multiply negative on both sides
y²+y+1/4=0
Use quadratic formula
b=1,c=1/4,a=1
y=-1±√1-1/2=-1/2
Now substitute y in x+y=-1
x-1/2=-1
x=-1+1/2
x=-1/2
Hence the two numbers are x =-1/2 and y=-1/2 whose product is 1/4 and which add to -1.

Un ascensor sube desde el primer piso al quinto piso, baja al segundo, sube al octavo. Si cada piso tiene 3 metros de altura, ¿cuántos metros recorrió el ascensor?
Answer:
El ascensor recorrió unos 39 metros
Step-by-step explanation:
Segun la pregunta cada cada piso tiene 3 metros de altura, por lo tanto para calcular los metros que recorrió el ascensor tenemos que hacer el siguiente calculo:
metros desde el primer piso al quinto piso=3 metros*4=12 metros
metros desde el quinto piso al segundo piso=3 metros*3=9 metros
metros desde el segundo piso al octavo piso=3 metros*6=18 metros
Por lo tanto los metros que recorrió el ascensor=12 metros+9 metros+18 metros
metros que recorrió el ascensor=39 metros
El ascensor recorrió unos 39 metros
