Answer:

(assuming the height is 13 and the width is 10 or vice versa) 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.

Find the area of the isosceles triangle with a base of 13 cm and a height of 10 cm.

The limit of the given infinite series is undefined.

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:

∑n=1∞(3/n)

This is a harmonic series with the form 1+1/2+1/3+1/4+... which is known to diverge. Therefore, the limit of the given infinite series is undefined.

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.

Answer:  The answer is 0.3

Step-by-step explanation:

Lily should expect to buy 1.5 boxes to get all four prizes.

This question belongs to the field of probability in Mathematics. The problem is asking how many boxes Lily should expect to buy in order to get all four prizes. This is a geometric problem because each box has a probability of 1/4 of containing a prize, and each trial is independent with the same probability of success. To solve this problem, we can use the concept of expected value.

The expected value is the average number of boxes Lily needs to buy to get all four prizes. The expected value can be calculated by multiplying the probability of each outcome by the number of boxes it takes to achieve that outcome, and then summing up these products:

Expected value = (1/4) * 1 + (1/4) * 2 + (1/4) * 3 + (1/4) * 4 = 1.5

Therefore, Lily should expect to buy approximately 1.5 boxes to get all four prizes.

Answer: 14

Step-by-step explanation:

the question is just asking you to replace the x and y with the corresponding numbers.

x = 4

y = -3

Since x is 4 squared it would be 16.

-4 times -3 equals positive 12.

That would make the equation

(16 + 12) divided by 2

16 + 12 = 28 divide that by 2 and you’ll get 14.

Answer: 14

Step-by-step explanation:

First plug 4 in for x.

4^2 is equal to 16 because 4 x 4 is 16.

Next, plug in -3 for y.

-4 x -3

4 times 3 is 12 and they are both negative, therefore it turns out as a positive 12.

Then add the numbers on the top of your equation.

16+12=28.

Finally divide the sum by 2.

28 divided by 2= 14

Your answer is 14.

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%

a) The function that represent this situation is y = 90 + 8x.

b)  His weight be after 8 weeks is 154 lbs.

Step-by-step explanation:

It is given that,

a) Write a function to represent this situation. Use x and y as your variables.

Hence the equation can be framed as,

Total weight = starting weight + weight gained in x weeks.

We know that, each week he gains 8 lbs. Therefore, for 8 weeks he gained 8x lbs of weight.

⇒ y = 90 + 8x.

∴ The function that represent this situation is y = 90 + 8x.

b) What would his weight be after 8 weeks?

To find his week after 8 weeks, substitute x=8 in the function y = 90 + 8x.

⇒ 90 + 8(8)

⇒ 90 + 64

⇒ 154 lbs.

∴ His weight be after 8 weeks is 154 lbs.

Answer:

88.2 squared

Step-by-step explanation:

The formula to find the area of a circle is a = pi * r ^2

Let's replace the values that we know.

a = 3.14 x 5.3 ^2

First, we should do 5.3 ^2, which is 28.09.

a = 3.14 x 28.09

Now we are able to do 3.14 x 28.09 which is 88.2026

But that isn't it! We need to round to the nearest tenth, which is this digit:

88.2026

Since next to the 2 there is a 0, you take out all the numbers after that 2. Which leaves you with:

88.2

Final answer:

The area of the round mirror with a radius of 5.3 inches, when calculated using the formula A = πr^2 and rounded to the nearest tenth, is 88.2 square inches.

To find the area of the round mirror with a radius of 5.3 inches, we will use the formula for the area of a circle, which is A = πr^2, where A is the area, π is approximately 3.14, and r is the radius of the circle.

Given that the radius of the mirror is 5.3 inches, we can substitute this value into the formula to find the area:

A = π(5.3)^2 ≈ 88.2 square inches.

Let's plug in the radius:

When rounded to the nearest tenth, the area of the mirror is 88.2 square inches.

Answer:

80 cm³

Step-by-step explanation:

Density = mass/volume

1.19 = 95.2/volume

Volume = 95.2/1.19

= 80

Answer:

80 cm cubed

Step-by-step explanation:

The density of a substance is denoted by d = m/V, where d is the density, m is the mass, and V is the volume.

Here, we know that the mass m = 95.2 grams and the density d = 1.19 g/cm cubed. So, plug these values into the formula:

1.19 = 95.2/V

Divide both sides by 1.19 and multiply both sides by V:

V = 95.2/1.19 = 80 cm cubed

Thus, the volume is 80 cm cubed.

Calculate the value of z and its probability, since with this we can know how likely it is that this will happen.

We have that the mean (m) is equal to 8.3, the standard deviation (sd) 1.2 and the sample size (n) = 15

They ask us for P (x =7.2)

For this, the first thing is to calculate z, which is given by the following equation:

z = (x - m) / (sd / (n ^ 1/2))

We have all these values, replacing we have:

z = (7.2 - 8.3) / (1.2 / (15 ^ (1/2))

z = -3.55

With the normal distribution table (attached), we have that at that value the approximate probability is:

P (z = -3.55) = 0.0001

The probability is 0.01 %

This affirms that the students do not sleep what the study says because the probability of this happening according to the survey is almost nil.
