Find the measure of all the angles.
Answer:
60
Step-by-step explanation:
All line segments are shown to be equal in length so all interior angles must equal 180 degrees.
Since all sides are equal length, the angles must be equal also.
All angles must be 60 degress and 60+60+60 =180
Answer:
60 degrees for all sides
Step-by-step explanation:
all equal and 60+ 60+ 60= 180
Write the binomial expansion of (t-3)^5
Answer:
Step-by-step explanation:
(t-3)^5 is the same as (t + (-3))^5
First: t starts at the highest power and goes down and (-3) starts at the lowest power and goes up
Second: from the Pascal triangles take the coefficients 1 5 10 10 5 1
[tex]1*t^{5} (-3)^{0} + 5*t^{4} (-3)^{1} +10*t^{3} (-3)^{2} +10*t^{2} (-3)^{3} +5*t^{1} (-3)^{4} +1*t^{0} (-3)^{5}[/tex]
Anything to power 0 is equal to 1
Negative number to an odd power is negative, to a even power is positive

A scientist determines that the number of bacteria in a culture is modeled by the formula A(t)=4,000e0.02t, where t is the number of minutes after observation begins.
Using the exponential model given, the number of bacteria in the culture after 9 minutes after the observation began will be 4789
Given the exponential model :
[tex] A(t) = 4000e^{0.02t} [/tex] [tex] A(t) = Number\:bacteria\:in\:the\:culture\:after\:t\:minutes [/tex] t = number of minutes after observation beginsThe number of bacteria in the culture 9 minutes after the observation began can be calculated thus :
[tex]t = 9 \: minutes [/tex]
Substitute 9 for t in the exponential equation :
[tex] A(t) = 4000e^{0.02\times9} [/tex]
[tex] A(t) = 4000e^{0.18} [/tex]
[tex] A(t) = 4000 \times 1.1972173 [/tex]
[tex] A(t) = 4788.87 [/tex]
Therefore, the number of bacteria in the culture after 9 minutes will be about 4789

Define what algebraic description is and give two examples
Answer:
Step-by-step explanation:
This helps in the representation of problems as mathematical expressions. It involves variables like x, y, z and mathematical operations like addition, subtraction, multiplication and division to form a meaningful mathematical expression. For example in algebra is 2x+4=8.
The graph of y = x^2 is translated 3 units to the left. The equation for this new graph is:
a) y = (x - 3)^2
b) y = x^2 + 3
c) y = (x + 3)^2
d) y = x^3 - 3
The next term in each of these Fibonacci sequences is found by adding together the two previous terms.
Work out the missing terms in each sequence.

Solve v times w squared+ y= x. Solve for w. Please show me how you got the answer!
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
let's solve for " w "
[tex]vw {}^{2} + y = x[/tex][tex]vw {}^{2} = x - y[/tex][tex] {w}^{2} = \dfrac{x - y}{v} [/tex][tex]w = \sqrt{ \dfrac{x - y}{v} } [/tex]Answer:
w = √( x - y ) / v
Step-by-step explanation:
in this situation, we are actually asked to make w the subject of the formula
this !means that we should make w be equal to every other variable meaning;
w = y + x
note that this is just an example
so, let us get started
we have;
vw² + y = x
first of all we have to move the y to the right hand side
it is more like collecting like terms so that at the end of the day we only end up with w on that side
vw² = x - y
now, we have to remove the ²
we will do that by square rooting both sides
√( vw )² = √( x - y )
the square root will remove the square because they are opposites of each other.
it is more like a multiplication sign canceling a division sign or when we bring a subtraction sign to the other side of the equation and it turns to an addition sign.
in our case, it is like bringing the square to the other side of the equation and it turns to a square root sign
so,
vw = √( x- y )
we ate almost done.
it is now time to remove the v by dividing through by v
this means that we remove the multiplication sign bonding the v and w through division just like the square root removing the square
vw / v = √( x - y ) / v
w = √( x - y ) / v
therefore , our answer is
w = √( x - y ) / v

What's the slope of (6, 5) and (3, 7.5) ?
Answer:
The slope of (6, 5) and (3, 7.5) is 5/-6.
As a decimal: (-0.83333333333...)
Step-by-step explanation:
Formula for slope:
[tex]m=\frac{y^2-y^1}{x^2-x^1}[/tex]
('m' means slope.)
[tex](x^1,y^1) =[/tex] coordinates of the first coordinate point
[tex](x^2,y^2)=[/tex] coordinates of the second coordinate point.
--------------------------
Coordinates:
[tex](6,5)(3,7.5)[/tex]
-------------------------
Now, I will simply plug the numbers into the formula.
[tex]m=\frac{7.5-5}{3-6} =\frac{2.5}{-3} =5/-6[/tex]
As a decimal: (-0.83333333333...)
The slope of the given points is 0.833
Slope, m, is given by the formula
[tex]m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
From the question
[tex]x_{1} = 6[/tex]
[tex]y_{1} = 5[/tex]
[tex]x_{2}=3[/tex]
[tex]y_{2}=7.5[/tex]
Putting the above parameters into the formula
[tex]m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
We get
[tex]m =\frac{7.5-5}{3-6}[/tex]
∴ [tex]m= \frac{2.5}{-3}[/tex]
[tex]m = 0.833[/tex]
Hence, the slope of the given points is 0.833

Answer:
4 bags, or 4 1/4 bags
Step-by-step explanation:
change 3 1/2 into a improper fraction, then change it to have a common denominator as 3/4. the expression would then be (14/4 + 3/4) divided by 1/2. 17/4 divided by 1/2 is 4 1/4. it would depend if they meant to fill the whole bag.

Answer:
[tex]y = \frac{4}{5} x - \frac{22}{5} [/tex]
Step-by-step explanation:
[tex]y = mx + b[/tex]
[tex] - 2 = \frac{4}{5} (3) + b \\ - 2 = \frac{12}{5} + b \\ - 2 - \frac{12}{5} = b \\ - \frac{10}{5} - \frac{12}{5} = b \\ - \frac{22}{5} = b[/tex]
Therefore, the equation of the line that goes through point (3, -2)and has slope ⅘ is
[tex]y = \frac{4}{5} x - \frac{22}{5} [/tex]
