The volume of the cone inscribed in the pyramid, calculated using the formula for the volume of a cone and the Pythagorean theorem, is 18√2π cubic inches.

In this question, we're asked to find the volume of the cone inscribed in a regular square pyramid. The volume V of a cone can be calculated using the formula V = 1/3 * pi * r^2 * h, where r is the radius of the base and h is the height of the cone. Since the cone is inscribed in the pyramid, its height and base radius would be the same as those of the pyramid.

However, the pyramid is a square pyramid with a base edge of 6 inches and a slant height of 9 inches. The height of the pyramid (and thus the cone) can be calculated using the Pythagorean theorem as √(9^2 - (6/2)^2), which is √(81 - 9) = √72 = 6√2.

The radius of the base of the cone is half of the base edge length of the pyramid, or 3 inches. So the volume of the cone is V = 1/3 * pi * 3^2 * 6√2 = 18√2π cubic inches.

Answer:

12.3 – 7.9x

Step-by-step explanation:

the product of + and - is -

Therefore,

8.9 – 1.4x + (–6.5x) + 3.4

= 8.9 – 1.4x –6.5x + 3.4

collect like terms

= – 1.4x – 6.5x + 3.4 + 8.9

= –7.9x + 12.3

= 12.3 – 7.9x

The exponential function, which means as you increase  in x ,  y increases exponentially.

It is required to represent the variable.

Exponential functions are patterns that get continuously multiplied by some number. It's exponential growth when the base of our exponential is bigger than 1, which means those numbers get bigger. It's exponential decay when the base of our exponential is in between 1 and 0 and those numbers get smaller.

Given that:

The standard form of an exponential growth or decay equation is

f(x) = a(b)^x

This is an exponential function, which means as you increase  x ,  y  increases exponentially. The initial amount is given by the value  a , which is easy to see (just let  x=0  and you have  y=a  left). The growth factor is the value  b .

If you restrict b such that  0<b<1 , the function will decay (represented below) and if  b>1 , the function will grow.

Therefore, the exponential function, which means as you increase  in x ,  y increases exponentially.

It is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Given:

Angle of elevation= 39.

Hypotenuse = 17 m

Using Trigonometry

cos 39 = adjacent side /hypotenuse

cos 39= base/17

0.777= base/17

base= 0.777*17

base= 13.21m

base= 13.2 m.(rounding off)

Hence, the distance from Roman's feet to the base of the flag pole 13.2 m.

Answer:

2

Step-by-step explanation:

Answer:

Option C

Step-by-step explanation:

It is really obvious that whenever the number of homework assignments he completes increases, his knowledge in the subject increases.  This will increase automatically his test score in Maths.

Thus we can expect a perfect linear association between number of assignments done and his test score.

The correlation coefficient which is a measure of linear association between two variables always lies between -1 and +1.

Hence Option a cannot be correct since the value is greater than 1.

b) r=0.5 gives a positive but not very strong association.  This is wrong as there is a strong association between the two variables

c) r=0.96 seems to be a correct answer as the positive and near to 1 r value confirms the linear strong positive association between the two variables.

D) r =-0.90 is wrong since there cannot be a negative association.

So only option right is option C

Step-by-step explanation:

The volume of the glass shell of the jar is 0.0136 ft³ and its weight is 2.24 lbs. The weight and volume of the water it will displace amounts to 2.24 lbs and 0.036 ft³ respectively. Consequently, the jar will sink approximately 2.2 inches into the water.

To begin, the volume of the glass shell of the jar will first need to be established. Given that the thickness of the glass is 3/16 inches, the outer radius of the jar is 3 inches + 3/16 inches = 3.1875 inches. To get the volume, utilise the formula for the volume of a cylinder, which is πr²h. Thus, with measurements converted to feet for the calculations (1 inch = 0.08333 foot), we have an external volume of π(0.265625 ft)² * 0.5 ft = 0.1118 ft³ and an internal volume of π(0.25 ft)² * 0.5 ft = 0.0982 ft³. Hence, the volume of glass is 0.1118 ft³ - 0.0982 ft³ = 0.0136 ft³

Next, the weight of the jar is determined by the formula mass = volume * density, so mass = 0.0136 ft³ * 165 lb/ft³ = 2.24 lbs.

To ascertain the weight of water the jar will displace, we consider the principle of buoyancy, which suggests that an object will displace a volume of fluid with a weight equal to its own weight. Thus, the weight of the water displaced is 2.24 lbs.

Then, the volume of this water is found with the formula volume = weight/density -> volume = 2.24 lbs / 62.5 lb/ft³ = 0.036 ft³.

Lastly, considering the jar will sink until the weight of the water being moved equals the weight of the jar. The volume of the water displaced equates to the submerged volume of the jar. Its depth in feet is then the volume divided by the cross-sectional area of the jar (internal radius), so the distance the jar sinks is roughly 0.036 ft³ / π(0.25 ft)²  = 0.18 ft -> convert to inches = 2.2 inches.

The ratio of A's to N's in the word BANANA is 2:1. This means that there are twice as many A's as there are N's in the word. Therefore, the correct answer is D: 2:1.

To find the ratio of A's to N's in the word BANANA, we need to count the number of A's and N's in the word.

1. Count the occurrences of A and N:

  In the word BANANA, there are 3 A's and 1 N.

2. Express the ratio:

  The ratio of A's to N's is 3:1.

3. Simplify the ratio:

To simplify the ratio, we can divide both parts by their greatest common divisor (GCD), which is 1 in this case, because 3 and 1 have no common divisor other than 1.

[tex]\[ \text{Ratio} = \frac{3}{1} = 3:1 \][/tex]

4. Check the given options:

A polynomial in two variables is in standard form if its monomial from left to right are arrangerd in descending order. We say that a monomial [tex]x^ay^b[/tex] is greater than a monomial [tex]x^{a^{\prime}}y^{b^{\prime}}[/tex] if [tex]a+b > a^{\prime} + b^{\prime}[/tex] or [tex]a+b=a^{\prime}+b^{\prime} \quad \text{and} \quad (a,b)>(a^{\prime},b^{\prime}})[/tex] in the alphabetical order.

Step-by-step explanation:

Final answer:

Molly can purchase a maximum of 15 school lunches per month with a budget of $30, considering each lunch costs $1.95.

Explanation:

The question asks how many school lunches Molly can buy if each lunch costs $1.95 and she wants to spend no more than $30 each month. To find out how many lunches Molly can buy, we divide her monthly budget by the cost of one lunch.

So, we perform the calculation: $30 ÷ $1.95 ≈ 15.38. Since Molly cannot buy a fraction of a lunch, we round down to the nearest whole number, which means Molly can buy 15 lunches at most in a month without exceeding her budget.

The value after 13 years will be 12576.9 dollars if the dollar value v(t) of a certain car model that is t years old is represented by the exponential function.

It is defined as the function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = a^x

where a is a constant and a>1

It is given that:

The dollar value v(t) of a certain car model that is t years old is given by the exponential function.

[tex]\rm V(t)=24,500(0.95^t)[/tex]

The initial value plug t = 0 in the above function:

V(0) = $24500

Plug t = 13 years in the above exponential function

[tex]\rm V(13)=24,500(0.95^1^3)[/tex]

After calculating, we get:

V(13) = 12576.88

V(13) = 12576.9 dollars

Thus, the value after 13 years will be 12576.9 dollars if the dollar value v(t) of a certain car model that is t years old is represented by the exponential function.
