The height of the cone is 24 cm.

The distance along the curved surface, measured from the edge at the top to a point on the circumference of the circle at the base, is known as the slant height of an object (such as a cone or pyramid). In other words, the slant height, represented either as s or l, is the shortest distance that may be traveled along the surface of the solid.

Slant height(l)=26cm

Radius(r)=10cm

It is known that, [tex]l^{2}=r^{2}+h^{2}[/tex]

Here, h is the height of the cone.

On substituting the values,

[tex]26^{2}= 10^{2}+h^{2}[/tex]

[tex]\\676=100+h^{2}\\[/tex]

[tex]h^{2}=676-100\\[/tex]

Answer:

1. can't answer, can only approximate

2. when f(x) = 2, x = -1

Step-by-step explanation:

We can't evaluate f(2)  because we don't have f(x), if we did, we would plug in 2 for x.

On the other hand, solve f(x) = 2 asks for what x is equal to when f(x) = 2, f(x) is just the value on the y axis in relationship with x (in short terms, the value on the y axis).

So looking at the graph, we cam see that when x = -1, f(x) = 2.

Answer:

Step-by-step explanation:

a = 12 mi

b ≈ 14.0 mi

c = 7 mi

m∠A ≈ 59.0 °

m∠B ≈ 91°

m∠C ≈ 30.0 °

The lengths of the triangle are:

a = 12 mi

b ≈ 14.0 mi

c = 7 mi

And the angles of the triangle are :

m∠A ≈ 59.0°

m∠B ≈ 91°

m∠C ≈ 30.0°

What are the angles in a triangle?

Every triangle has interior angles that total 180.

Angles in a triangle are the total (sum) of the angles at each of its three vertices.

Given, in a triangle ∠B is = 91°

length of c = 7 mi

              a = 12 mi

We need to find the missing angles and side length of b.

⇒ b² = a² ₊ c² ₋ 2accosB

⇒ b/sinB = a/sinA = c/sinC

b² = 12² ₊ 7² ₋ 2(12)(7)cos91°

b² = 144 ₊ 49 ₋ 2(84)cos91°

b² = 193 ₋ 168 cos 91°

b² = 195.856

b=√195.856

b = 14.0 mi

⇒14.0/sin91° = 12/sinA

⇒ sinA = 12sin91°/14.0

sin A = 0.857

A = arcsin(0.857)

A = 59.0°

∴ C = 180° ₋ (sum of two angles in a triangle)

C = 180 ₋ (91° ₊ 59°)

C = 180 ₋ 150°

C = 30°

Hence we get the angles in the triangle as m∠A = 59.0°, m∠B = 91° and  m∠C = 30°

Bobby will have $557 in his account after 4 years.

Simple interest is calculated based on a loan's principal or the initial deposit into a savings account.

Simple interest doesn't compound, therefore a creditor will only charge interest on the principal sum, and a borrower will never be required to pay further interest on the interest that has already accrued.

Simple interest = (principal amount×Rate of interest×time-period)/100

The principal amount deposited was $500.

The rate of interest given by the bank is 2.85%.

The duration of deposit is 4 years.

Simple interest = (500×2.85×4)/100

                         = 57

Simple interest given by the bank after 4 years is $57.

The total sum of money Bobby will have in his bank is $500 + $57 = $557.

Therefore, after 4 years Bobby will have $557 in his account.

Step-by-step explanation:

Area of Part of a Circle = (θ/360)[tex]\pi r^{2}[/tex]

We first find the area of CAB first.

Radius of CAB = AB = 6cm

θ  = 112

Area of CAB = [tex]\frac{112}{360} \pi (6)^{2} \\=\frac{56}{5} \pi cm^{2}[/tex]

Next we will find the area of FAE.

Radius of FAE = AE = 4cm

Area of FAE = [tex]\frac{112}{360} \pi (4)^{2} \\=\frac{224}{45} \pi cm^{2}[/tex]

Lastly,

Area of Shaded Region = Area of CAB - Area of FAE

= [tex]\frac{56}{5} \pi -\frac{224}{45}\pi \\=\frac{56}{9} \pi cm^{2}[/tex]

Therefore the answer is D.

Equilateral Triangle: All 3 sides of a Triangle are equal in length

Isosceles Triangle: Two sides of Triangle are equal in length

Scalene: Triangle has different side lengths

So, for example, when you see Q1, you estimate the length of each side and think it is Scalene Triangle because all of its sides are of different length. (You can also use a ruler to find out the side lengths if it can be used for scale)

Q2, you can say that the side lengths AC and BC look similar, so it is an Isosceles Triangle

Q6, when you look at the side lengths, you can tell it is an equilateral Triangle because all the sides are equal in length

You can try the rest and check for yourself. If you still have any doubts, you could ask me. I hope this information helps you.

Let us first define what any of these terms mean.

The mean is found by adding all the numbers in the set, and dividing the sum by how many numbers are found in the set.

> Given set {5, 12, 6, 3, 8, 16, 8, 6}, the sum of the numbers is 5 + 12 + 6 + 3 + 8 + 16 + 8 + 6 = 64. 64 ÷ 2 = 32. Thus, the mean is 32.

The median is found by finding the number in the middle of the set, and dividing it by 2. This is easy in odd numbers as there is only one number in the middle that is the same amount of numbers left and right proportionally. However, in even numbers, there are two middles to be proportional. If it as an even number, then add the 2 middles together, and divide by 2.

> Given set {5, 12, 6, 3, 8, 16, 8, 6}, this set has an even number of numbers in the set. Thus, the middles are 3 and 8. 3 + 8 = 11, and 11 ÷ 2 = 5.5. Thus, the median is 5.5.

The mode is the number that most frequently appears in the set. In this case, we have 2 frequent numbers. That is 6 and 8. They both appear 2 times separately. Thus, 6 and 8 are the modes of this set.

The range is the difference (i.e subtraction) between the largest number on the set and the smallest number on the set.

> Given set {5, 12, 6, 3, 8, 16, 8, 6}, the range is 16-3 or 13. Thus, the range is 13.

Now that we have the definitions, we can compute the other set very easily.

> Given set {2, 7, 4, 11, 12, 4, 6}, the mean is 18.

> Given set {2, 7, 4, 11, 12, 4, 6}, the median is 5.5.

> Given set {2, 7, 4, 11, 12, 4, 6}, the mode is 4.

> Given set {2, 7, 4, 11, 12, 4, 6}, the range is 10.

The difference between causation and correlation is that, Causation is characterized by cause-and-effect while correlation establishes a probable relationship.

While Causation is characterized by a situation in which an action certainly causes an outcome and hence, is described as a cause-and-effect relationship, Correlation on the other hand only establishes a relationship between the two events and doesn't necessarily ascertain the occurrence of the other event .

Step-by-step explanation:

Marked price = $36.00

Sales tax = 7%

= 7% of marked price

= 7% of $36 [Key: "of" means "to multiply"]

= 7/100 * 36

= 0.07 * 36

= $2.52

= Marked price + sales tax

= $36 + $2.52

= $38.52

[tex]\rule[225]{225}{2}[/tex]

The total cost of the jacket was the amount of  $38.52. The correct answer is option (d).

To find the total cost of the jacket after adding a 7% sales tax, we need to calculate the tax amount and add it to the original price.

Calculate the tax amount:

Tax amount = 7% of $36.00

Tax amount = 0.07 × $36.00

Tax amount = $2.52

Add the tax amount to the original price:

Total cost = $36.00 + $2.52

Total cost = $38.52

Thus, the total cost of the jacket was the amount of  $38.52.

Hence, the correct answer is option (d).
