Find the lateral area of the following
cone. Leave your answer in terms of .
12 cm
5 cm
LA = [ ? ]7 cm2

Answers

The lateral surface area of the cone will be 65π square cm.

What is the lateral surface area of a cone?

Let d be the diameter of the base circle, l be the slant height, and h be the height of the cone.

Then the lateral surface area of the cone will be

LSA = πrl

Then the slant height is given as

l² = r² + h²

l² = 5² + 12²

l² = 25 + 144

l² = 169

 l = 13 cm

Then the lateral surface area will be

LSA = π × 5 × 13

LSA = 65π cm²

More about the lateral surface area of a cone link is given below.

Subtract (5u + 6v) from (8u + 10v)

Answers

Answer:

-3u-4v

Step-by-step explanation:

5u+6v-(8u+10v)

=5u+6v+-1(8u+10v)

=5u+6v+-1(8u)+-1(10v)

=5u+6v+-8u+-10v

(combine like terms)

=(5u+-8u)+(6v+-10v)

=-3u-4v

The value of the subtraction will be equal to -3u-4v.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the two expressions are (5u + 6v) and (8u + 10v). The subtraction will be calculated as,

5u+6v-(8u+10v)

S =5u+6v+-1(8u+10v)

S =5u+6v+-1(8u)+-1(10v)

S =5u+6v+-8u+-10v

(combine like terms)

S =5u+6v+-8u+-10v

S =(5u+-8u)+(6v+-10v)

S =-3u-4v

Therefore, the value of the subtraction will be equal to -3u-4v.

A teacher would like to estimate the mean number of steps students take during the school day. To do so, she selects a random sample of 50 students and gives each one a pedometer at the beginning of the school day. They wear the pedometers all day and then return them to her at the end of the school day. From this, she computes the 98% confidence interval for the true mean number of steps students take during the school day to be 8,500 to 10,200. If the teacher had used a 90% confidence interval rather than a 98% confidence interval, what would happen to the width of the interval

Answers

Answer:

The answer is "It would decrease, but not necessarily by 8%".

Step-by-step explanation:

They know that width of the confidence level is proportional to a confidence level. As just a result, reducing the confidence level decreases the width of a normal distribution, but not with the amount of variance in the confidence level. As just a result, when a person teaches a 90% standard deviation rather than a 98 percent normal distribution, the width of the duration narrows.

Answer:

89 degrees

Step-by-step explanation:

Since these angles make up a triangle, we know that the total of these angles will make 180 degrees. So, we need to set the equations up appropriately, and solve for x:

[tex]180=(4x+1)+(2x-6)+(6x-7)\\180=12x-12\\192=12x\\x=16\\[/tex]

Then, you plug 16 back into the equation for angle J, and simplify:

[tex](6(16)-7)\\(96-7)\\(89)[/tex]

Therefore, the answer is 89 degrees.

Camden needs to lease out a music studio to record his new album. The studio charges an initial studio-use fee plus an hourly fee for each hour in the studio. The studio charges $50 per hour of use and the total cost charged for 5 hours is $700. Write an equation for the function P ( t ) , P(t), representing the amount of money Camden would have to pay to use the studio for t t hours.

Answers

Answer: [tex]P(t)=450+50t[/tex]

Step-by-step explanation:

Given

Studio charge $50 per hour and fixed charge for initial use

For 5 hours, it charges $700

Suppose x is the fixed charge

[tex]\therefore 700=x+50\times 5\\\Rightarrow x=700-250\\\Rightarrow x=\$450[/tex]

For t hours, studio charges

Mammography is specialized medical imaging that uses a low-dose X-ray system to see inside the breasts. A mammography exam, called a mammogram, aids in the early detection and diagnosis of breast diseases in women. Imaging with X-rays involves exposing a part of the body to a small dose of ionizing radiation to produce pictures of the inside of the body. One recent advance in mammography is digital mammography. With digital mammography, the X-ray film is replaced by electronics that convert X-rays into mammographic pictures of the breasts. This system is similar to those found in digital cameras, and its efficiency enables better pictures with a lower radiation dose.Mammography,Radiological Society of North AmericaWhat is the purpose of mammography?treat breast cancerdetect breast cancerprevent breast cancerresearch breast cancer Which one of the following is an example of parasitism?a.
