The measure of a base angle of an isosceles tri-
angle is 13 more than 3 times the measure of the
vertex angle. How many degrees are in the vertex
angle?
The vertex angle of the isosceles triangle is 22°.
What is isosceles triangle?
A triangle with two equal sides is said to be isosceles. Also equal are the two angles that face the two equal sides. In other terms, an isosceles triangle is a triangle with two sides that are the same length.
We know that an isosceles triangle is composed of a vertex angle and two base angles. The base angles are congruent to each other. We also know that the sum of a triangle's angles is 180degrees.
Base angle = 3vertex angle+13.
=> 2base angle + vertex angle = 180°
=> 2(3 vertex angle +13)+vertex angle = 180°
=> 6 vertex angle+26+vertex angle = 180
=> 7 vertex angle = 180-26
=> 7 vertex angle = 154
=> vertex angle = 154/7 = 22°.
Hence the vertex angle of the isosceles triangle is 22°.

One kind of average is the mean. It is calculated by dividing the total number of values in a list of values, such as measurements or numbers, by the total number of values in the list.
What is the mean in maths?There are various mean types in mathematics, particularly in statistics. Each mean helps to summarise a certain set of data, frequently to help determine the overall significance of a specific data set.The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.Only numerical variables—regardless of whether they are discrete or continuous—can be used to determine the mean. Simply dividing the total number of values in a data set by the sum of all of the values yields it.Given data :

An ice cream cone with a 2cm radius has a volume of 75.36 cubic cm how tall is the ice cream cone
Step-by-step explanation:
reading the question thoroughly, we find out that volume (V) and radius (r) of the cone is given, and we just have to find out the length (h) of the cone
V = πr²h/3
Putting the given values in place,
V = 75.36 cm³
V = 75.36 cm³r = 2 cm
V = 75.36 cm³r = 2 cmπ = 3.14
Now, since we calculating for h, we can interpret the formula in the terms of h, i.e.
h = 3V/(πr²)
h = 3×75.36/(3.14×2²)
h = 226.08/12.56
h = 18 cm
Thus, the height of the ice cream cone is 18cm

It can be helpful to classify a differential equation, so that we can predict the techniques that might help us to find a function which solves the equation. Two classifications are the order of the equation -- (what is the highest number of derivatives involved) and whether or not the equation is linear .Linearity is important because the structure of the the family of solutions to a linear equation is fairly simple. Linear equations can usually be solved completely and explicitly. Determine whether or not each equation is linear:1. (1+y2)(d2y/dt2)+t(dy/dt)+y=et2. t2(d2y/dt2)+t(dy/dt)+2y=sin t3. (d3y/dt3)+t(dy/dt)+(cos2(t))y=t34. y''-y+y2=0You have 10 choices to choose for each problem:a. 1st. order linear differential equationb. 2nd. order linear differential equationc. 3rd. order linear differential equationd. 4th. order linear differential equatione. 5th. order linear differential equationf. 1st. order non-linear differential equation=g. 2nd. order non-linear differential equationh. 3rd. order non-linear differential equationi. 4th. order non-linear differential equationf. 5th. order non-linear differential equation
The coefficient of the second derivative (t2) is constant, so the equation is linear.
1. (1+y2)(d2y/dt2)+t(dy/dt)+y=et2 -> 2nd. order non-linear differential equation
2. t2(d2y/dt2)+t(dy/dt)+2y=sin t -> 2nd. order linear differential equation
3. (d3y/dt3)+t(dy/dt)+(cos2(t))y=t3 -> 3rd. order non-linear differential equation
4. y''-y+y2=0 -> 2nd. order non-linear differential equation
The order of a differential equation is the highest derivative involved in the equation. For example, in the equation 1 + y2(d2y/dt2) + t(dy/dt) + y = et2, the highest derivative is the second derivative (d2y/dt2), so this equation is of 2nd order. Linearity is determined by whether the coefficients of each derivative are constants, or whether they depend on the function y and its derivatives. In this equation, the coefficient of the second derivative (1+y2) is not constant, so the equation is non-linear. Similarly, in equation t2(d2y/dt2)+t(dy/dt)+2y=sin t, the coefficient of the second derivative (t2) is constant, so the equation is linear.

If f(x)=5x^6-2x^2-5, then what is the remainder when f(x) is divided by x+2?
Answer:
To find the remainder when f(x) is divided by (x-a) , we substitute x = a in the polynomial f(x) and we get the remainder.
remainder = f(a)
In this case, we have f(x)=5x^6-2x^2-5, and x+2 is the divisor and we substitute x=-2
so, remainder = f(-2) = 5*(-2)^6-2*(-2)^2-5 = -643
So, the remainder when f(x) is divided by x+2 is -643

Calculate sin 300° − cos 945° + tan(−675°) without using calculator �
Answer:
Step-by-step explanation:
sin 300° = sin (300° - 360°) = sin (-60°) = -sin 60° = -(1/2)
cos 945° = cos (945° - 360°) = cos (585°) = cos (-295°) = -cos 295°
tan (-675°) = -tan (675° - 360°) = -tan 315°
so
sin 300° − cos 945° + tan(−675°) = -(1/2) - (-cos 295°) + (-tan 315°)
It is not a trivial task to simplify the above equations without using a calculator.
= -(1/2) + cos 295° + tan 315°
As we know that cos(x) = cos(360°-x) = -cos(x) and tan(x) = -tan(360°-x) = -tan(x)
= -(1/2) - cos 295° - tan 315°
As we know that cos(295°) = cos(360°-65°) = cos(65°) and tan(315°) = tan(360°-45°) = tan(45°)
= -(1/2) - cos(65°) - tan(45°)
= -(1/2) - 0.4226 - 1
= -0.5 - 0.4226 - 1

feet in a mile)
The mountain is ___ feet high?
The peak of the mountain has a height of 14805 feet.
How to determine the height of a mountain according to atmospheric pressure model
In this problem we find the case of an exponential function for atmospheric pressure (p), in pounds per square inch, in terms of height (x), in miles, whose expression is introduced below:
[tex]p(x) = 14.7 \cdot e^{- 0.21\cdot x}[/tex], for x ≥ 0.
If we know that p(x) = 8.164 lb / in², then the height of the peak of a mountain is:
[tex]8.164 = 14.7\cdot e^{-0.21 \cdot x}[/tex]
[tex]0.555 = e^{-0.21\cdot x}[/tex]
Then, by relationship between exponential and logarithmic functions and logarithm properties:
㏑ 0.555 = - 0.21 · x · ㏑ 1
㏑ 0.555 = - 0.21 · x
x = - (1 / 0.21) · ㏑ 0.555
x ≈ 2.804

skee ball refer to exercise 4. make a histogram of the probability distribution. describe its shape.
Ten to fifty is the range of the scores. The most frequent result is a 10 with a right-skewing bias.
Probability histogram
The height of each bar must be equal to the probability, the width of each bar must be the same, and the bars must be centered on the amount of money gathered.
The distribution is skewed to the right because the highest bar in the histogram is to the left and there is a tail of lower bars to its right.
The most frequent score is 10 due to the fact that the top bar in the histogram is centered at 10.
The result is:
Ten to fifty is the range of the scores.
The most frequent result is a 10 with a right-skewing bias.

The number of cycles per day and the production quantity per cycle.
Number of cycles per day = (Product Daily Quantity/Production Quantity per Cycle)
For Product A:
Number of cycles per day = (18/Production Quantity per Cycle)
For Product B:
Number of cycles per day = (16/Production Quantity per Cycle)
For Product C:
Number of cycles per day = (6/Production Quantity per Cycle)
For Product D:
Number of cycles per day = (14/Production Quantity per Cycle)
Using the data from the excel file, we can calculate the production quantity per cycle and the number of cycles per day.
For Product A:
Production Quantity per Cycle = 18/3.75 = 4.8
Number of cycles per day = 3.75
For Product B:
Production Quantity per Cycle = 16/2.5 = 6.4
Number of cycles per day = 2.5
For Product C:
Production Quantity per Cycle = 6/1.5 = 4
Number of cycles per day = 1.5
For Product D:
Production Quantity per Cycle = 14/2.25 = 6.2
Number of cycles per day = 2.25
Therefore, for this set of vehicles, the number of cycles per day and the production quantity per cycle are as follows:
Product A: 3.75 cycles per day, 4.8 units per cycle
Product B: 2.5 cycles per day, 6.4 units per cycle

Two investments totaling $64,500 produce an annual income of $3270. One investment yields 8% per year, while the other yields 2% per year. How much is invested at each rate?
Answer:
The amount invested at 8% is 64,500-32,000 = 32,500
Step-by-step explanation:
one investment: 3%, amount: x
the other: 8%, amount: 64,500-x because x is invested at 3%
0.03x+0.08(64,500-x) = 3,560
0.03x+5,160-0.08x = 3,560
-0.05x = -1,600 divide both sides by 0.05 and remember that -/- = +
x = 32,000 This is the amount invested at 3%
The amount invested at 8% is 64,500-32,000 = 32,500
Use the given information to determine the number of elements in each of the four disjoint subsets in the following Venn diagram: n BAnBA' nB n(A) = 20 n(B) = 50, n(A nB) = 0, n(U) = 200 4' nB' (A) Find n(An B): n(An B) = (B) Find n(A n B'): n(Anb) = (C) Find n(A' n B): n(A' n B) =Ml (D) Find n(A' n B') n(A' 0 B') =
The value of the following venn expressions of sets is (A)=1 ,(B)=50,(C)=20 and (D)=130 respectively.
A Venn diagram is a diagram that helps us visualize the logical relationship between sets and their elements and helps us solve examples based on these sets. A Venn diagram typically uses intersecting and non-intersecting circles (although other closed figures like squares may be used) to denote the relationship between sets.
Symmetric difference between two sets A and B defined by,
AΔB=(A\B) ∪ (B\A)
AΔB=(A∩B') ∪(A'∩B).
we have n(A)=20 n(B)=50, n(A∩B)=0, n(U)=200
SO,
(A) Find n(A∩B)
n(A∩B) =0 (GIVEN)
(B) Find n(A∩B')
n(A∩B') =n(B)-n(A∩B)
= 50-0
=50
(C) Find n(A∩B')
n(A'∩B) =n(A)-n(A∩B)
=20-0
=20
(D) n(A'∩B') =n(U)-n(A'∩B)-n(A∩B)-n(A∩B')
=200-20-0-50
= 130.
thus, the above is the value of expression.
