Find measure of arc CE
A. 40°
B.50°
C.75°
D.80°
Answer:
Option B is the right choice.
Step-by-step explanation:
Given:
An are CE and an inscribed angle CBE.
Measure of inscribed angle CBE = 25 °
We have to find the measure of the arc CE.
Concept:
An inscribed angle is an angle with its vertex on the circle.The measure of an inscribed angle is half the measure the intercepted arc. Measure of inscribed angle = 1/2 × measure of intercepted arc .To find the measure of arc CE.
⇒ [tex]\angle CBE = \frac{1}{2} \times m\ (arc\ CE)[/tex]
⇒ [tex]2\times \angle CBE = m\ (arc\ CE)[/tex]
⇒ [tex]2\times 25 = m\ (arc\ CE)[/tex]
⇒ [tex]50 = m\ (arc\ CE)[/tex]
Measure of intercepted arc CE = 50 degrees.
The measure of arc CE = 50° so, option B is the right choice.

The nth term of a sequence is 8 - n. a)work out the first three terms of the sequence b) work out the value of the first negative term of the sequence
Answer:
see explanation
Step-by-step explanation:
To calculate the first 3 terms substitute n = 1, 2, 3 into the n th term formula
(a)
8 - 1 = 7
8 - 2 = 6
8 - 3 = 5
The first 3 terms are 7, 6, 5
(b)
The first negative term wii occur when n > 8, that is n = 9, thus
8 - 9 = - 1 ← first negative term
The first three terms of the sequence defined by 8 - n are 7, 6, and 5. The first negative term is when n equals 9.
Explanation:The nth term of a sequence is defined by 8 - n. This means that you subtract the term number (n) from 8 to get the value of the term.
To work out the first three terms of the sequence, substitute n = 1, 2, and 3 into the nth term. So, the first term is 8 - 1 = 7, the second term is 8 - 2 = 6, and the third term is 8 - 3 = 5.To find the first negative term of the sequence, you need to determine the value of n when 8 - n becomes less than 0. If you set 8 - n to be less than 0 and solve for n, you will find that n > 8. Therefore, the first negative term occurs when n = 9 (since n must be an integer, the number immediately greater than 8 is 9).Learn more about Sequence Terms here:https://brainly.com/question/35448108

Find the area of the isosceles triangle.
13 cm/
10 cm
Answer:
(assuming the height is 13 and the width is 10 or vice versa) 65
Step-by-step explanation:
a = 1/2 base × height
1/2 13 × 10 or 10×13
130 ÷ 2
65
Area of isosceles triangle = [tex]\( \frac{13\sqrt{231}}{4} \)[/tex] square centimeters, approximately 43.03 square centimeters.
To find the area of an isosceles triangle, you can use the formula:
[tex]\[ Area = \frac{1}{2} \times \text{base} \times \text{height} \][/tex]
Since it's an isosceles triangle, the height divides the triangle into two right-angled triangles of equal size.
Given:
Base = 13 cm
Height = ?
To find the height, we can use the Pythagorean theorem.
Let's denote the height as [tex]\( h \),[/tex] and half of the base (since the triangle is isosceles, and the height splits the base into two equal parts) as [tex]\( \frac{13}{2} \).[/tex]
Then, using the Pythagorean theorem:
[tex]\[ (\text{height})^2 + \left(\frac{13}{2}\right)^2 = 10^2 \]\[ (\text{height})^2 + \left(\frac{13}{2}\right)^2 = 100 \]\[ (\text{height})^2 + \frac{13^2}{2^2} = 100 \]\[ (\text{height})^2 + \frac{169}{4} = 100 \]\[ (\text{height})^2 = 100 - \frac{169}{4} \]\[ (\text{height})^2 = \frac{400}{4} - \frac{169}{4} \]\[ (\text{height})^2 = \frac{231}{4} \][/tex]
Now, let's solve for the height:
[tex]\[ \text{height} = \sqrt{\frac{231}{4}} \]\[ \text{height} = \frac{\sqrt{231}}{\sqrt{4}} \]\[ \text{height} = \frac{\sqrt{231}}{2} \][/tex]
Now that we have the height, we can calculate the area using the formula:
[tex]\[ Area = \frac{1}{2} \times \text{base} \times \text{height} \][/tex]
Substituting the values:
[tex]\[ Area = \frac{1}{2} \times 13 \times \frac{\sqrt{231}}{2} \]\[ Area = \frac{13 \sqrt{231}}{4} \][/tex]
So, the area of the isosceles triangle is [tex]\( \frac{13 \sqrt{231}}{4} \)[/tex] square centimeters.
The complete question is here.

3. Assume lines that look tangent are tangent. Find the length of the line
segment indicated by the ?
Answer:
20
Step-by-step explanation:
The point of contact of the tangent and the diameter of the circle is a right angle.
Thus the triangle with legs 12 and 2 × 8 = 16 is right
Using Pythagoras' identity.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
?² = 12² + 16² = 144 + 256 = 400 ( take the square root of both sides )
? = [tex]\sqrt{400}[/tex] = 20
Final answer:
The question deals with mathematics, specifically the slope of tangent lines, use of the Pythagorean theorem, and solving scale ratios and proportions. Students need to find specific lengths using provided endpoints, hypotenuse calculations, and scale conversions.
Explanation:
The student appears to be asking about finding the length of a line segment in a geometric context, possibly related to tangents to curves and the Pythagorean theorem. The student is likely working with a diagram or curve not provided here, so it is important to make use of available data points or diagrams in the course material. Furthermore, when working with scales and ratios for determining lengths, the process involves setting up a proportion, solving for the unknown value by cross-multiplying and dividing.
For the slope of the tangent line to a curve:
Identify the endpoints of the tangent line that corresponds to given positions and times.
Find the slope of the tangent line, denoted as 'v', by using the change in position over the change in time.
For the Pythagorean theorem:
Calculate the length of the hypotenuse as the square root of the sum of the squares of the other two sides.
Use significant figures appropriately to represent the precision of your result.
For solving ratios and proportions:
Set up the proportion based on given scale lengths and distances.
Solve for the unknown by cross-multiplying and dividing.

than 3 or a six on a standard 6-sided die?
a. 1/6
b. 1/3
c. 1/2
d. 1
e. 3
I'm giving 20 points if you answer correctly
Answer:
1/2
Step-by-step explanation:
There are 2 numbers less than 3. (1 and 2) and one 6 on a dice. Therefore there is a 3 out of 6 chance of rolling one of these 3 numbers (1, 2, and 6). This can be represented as 3/6 which would simplify to 1/2 or 50%.
It can also be found this way...
Probability = Number of desired outcomes ÷ number of possible outcomes. Therefore 3 ÷ 6 = 0.5 which is equal to 50% or 1/2.

Step-by-step explanation:
Odette has two investments that she purchased at the same time. Investment 1 cost $10,000 and earns 4% interest each year. Investment 2 cost $8000 and earns 6% interest each year.
Write exponential growth functions
that could be used to find v1(t) and v2(t), _________________________________
the values of the investments after t years.
Find the value of each investment after 5 years.
Explain why the difference between their values, ____________________________ which was initially $2000, is now less
Answer: The functions are v1(t)=10000*(1.04)^5 and v2(t)=8000(1.06)^5
v1(5)=12166$
v2(5)=10705 $
Step-by-step explanation:
Given:
Investment cost for 1st=10,000$ ,at 4%rate.
Investment cost for 2nd=8000$ ,at 6% rate.
To Find:
Exponential growth functions ,
that could be used to find v1(t) and v2(t),
the value of each investment after 5 years
And difference between their values.
Solution:
Consider for 1st investment function be v1(t) and for 2nd be v2(t)
and t be time period
Exponential growth is given by, as time function,
v(t)=initial cost*(1+rate)^time period.
for 1st investment its cost is 10000$ at 4 % rate.
[tex]v1(t)=10000(1+0.04)^t[/tex]
[tex]v1(t)=10000(1.04)^t[/tex]
for 2nd investment its cost is 8000$ at 6% rate.
[tex]v2(t)=8000(1+0.06)^t[/tex]
[tex]v2(t)=8000(1.06)^t[/tex]
For t=5 calculating for both investment,
[tex]v1(5)=10000(1.04)^5[/tex]
[tex]=10000*1.2166[/tex]
v1(5)=12166 $
For 2nd investment,
[tex]v2(5)=8000(1.06)^5[/tex]
[tex]=8000*1.3382[/tex]
v2(t)=10705.8 $
Now after 5 years the difference is =v1(t)-v2(t)
Which is about 1460 $ only.
This because of the both functions depends upon time,initial investment and rate of interest .
Here time period being same.But the rate of interest are different and initial values are different.

When does the graph of a quadratic function open up?open down?
The graph of a quadratic function opens up when a (<,>,=) 0 and opens down when a (<,>,=) 0
Answer:
1. >
2. <
Step-by-step explanation:
When a > 0, the graph opens upwards, or positively, because the way the line curves is determined by a.
When a < 0, the graph opens downwards, or negatively, for the same reason.
Final answer:
The graph of a quadratic function opens upwards when the coefficient of the squared term is positive (a > 0), and opens downwards when this coefficient is negative (a < 0).
Explanation:
The graph of a quadratic function opens up or down based on the sign of the coefficient of the squared term (usually represented as 'a' in the quadratic equation ax2 + bx + c). When this coefficient a is positive (a > 0), the parabola opens upwards. Conversely, if the coefficient a is negative (a < 0), the parabola opens downwards. The orientation of the parabola reflects whether the quadratic function has a minimum value (opening upwards) or a maximum value (opening downwards).

Which triangle defined by the given points on the coordinate plane is similar to the triangle illustrated?
Answer:
The correct option in the attached image is:
D. (-1, 1), (-1, 5), (-7, 1)
Step-by-step explanation:
Please refer to the attached image.
The length of the horizontal segment of the graphed triangle is 3. The length of the vertical segment of the triangle graphed is 2. We will use the Pythagorean theorem to find the length of the missing side thus:
x² = 2²+3²
x² = 4+9
x² = 13
x = √13 or 3.6
This makes our side lengths 2, 3, and 3.6
For option A, our vertices are (-1, 1), (-1, 4), (-6, 1). This means the length of the horizontal segment 5 and the length of the vertical segment 3. This missing side length is calculated thus:
x² = 5²+3²
x² = 25+9
x² = 34
x = √34 or 5.83
This is not proportional to the triangle drawn, so it is not similar.
For option B, our vertices are (-1, 1), (-1, 5), and (-6, 1). This makes the horizontal segment 5 units long and the vertical segment 4 units long. This makes the missing side length
x² = 4²+5²
x² = 16+25
x² = 41
x = √41 or 6.4
These are not proportional to the triangle drawn, so the triangles are not similar.
For option C, our vertices are (-1, 1), (-1, 4) and (-7, 1). This makes the length of the horizontal segment 6 and the length of the vertical segment 3. This makes the missing side length
x² = 3²+6²
x² = 9+36
x² = 45
x = √45 or 3√5 or 6.7
These sides are not proportional to the sides of the triangle drawn, so the triangles are not similar.
For option D, our vertices are (-1, 1), (-1, 5) and (-7, 1). This makes the length of the horizontal segment 6 and the length of the vertical segment 4. This makes the missing side length
x² = 6²+4²
x² = 36+16
x² = 52
x = √52 or 2√13 or 7.21
These sides are all twice as long as the sides of the triangle drawn, this indicates that the triangles are similar. Therefore our answer is D.

What is the limit of the infinite series ?
∑n=1∞(3n^5/6n^6+1)
The limit of the given infinite series is undefined.
Explanation:The given series is:
∑n=1∞(3n5/6n6+1)
To find the limit, we can simplify the series by dividing the numerator and denominator by the highest power of n:
∑n=1∞(3/n-1/6n-1+n-6)
As n approaches infinity, the terms containing n-1 and n-6 approach 0, so we are left with:

3. The resting heart rates for a sample of individuals are normally distributed with a mean of 70 and a standard deviation of 10 Find the percentage rates of heart rates greater than 50.
PLSSS
Answer:
Step-by-step explanation:
Looking at the information given, the population mean and population standard deviation are known. We would apply the formula
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = population standard deviation
From the information given,
µ = 70
σ = 10
1) x = 60
The probability that the heart rate if an individual is less than 60 is expressed as
P(x < 60)
z = (60 - 70)/10 = - 1
Looking at the normal distribution table, the probability corresponding to the z score is 0.16
The percentage rates of heart rates less than 60 is 0.16 × 100 = 16%
2) x = 80
The probability that the heart rate if an individual is less than 80 is expressed as
P(x < 80)
z = (80 - 70)/10 = 1
Looking at the normal distribution table, the probability corresponding to the z score is 0.84
The percentage rates of heart rates less than 80 is 0.84 × 100 = 84%
3) x = 50
The probability that the heart rate if an individual is greater than 50 is expressed as
P(x > 50) = 1 - P(x ≤ 50)
z = (50 - 70)/10 = - 2
Looking at the normal distribution table, the probability corresponding to the z score is 0.23
P(x > 50) = 1 - 0.23 = 0.77
The percentage rates of heart rates greater than 50 is 0.77 × 100 = 77%
Absolute 10.7 of percent 11
Answer: = 11.88
This is a 3 step / 4 show workings.
10.7 + Percentage increase = 11%
10.7 + (11% × 10.7) = 10.7 + 11% × 10.7
(1 + 11%) × 10.7 = (100% + 11%) × 10.7
111% × 10.7 = 111 ÷ 100 × 10.7
111 × 10.7 ÷ 100 = 1,187.7 ÷ 100
11.877 ≈ 11.88
