8. Negative three times the sum of a number and two is fifteen

Answers

Answer:

-3(n + 2)= 15

Step-by-step explanation:

Based on this question, we know that the equation involves multiplication. Here we start our equation with -3!

Then it says "times the sum of a number and two" So let's just say the "number" is "n". The word "sum" means the answer to an addition problem, thus we know that we are adding "n" and 2. Let's put that in parenthesis!

-3(n+2)

And it says "is fifteen" which also means "equals to fifteen"

Therefore, the answer is:

-3(n + 2) = 15

Answers

Answer:

steps below

Step-by-step explanation:

cot 10° * cot 20° * cot 70° * cot 80° * cot 45°

= (cos 10°/sin 10°)*(cos 20°/sin 20°)*(cos 70°/sin 70°)*(cos 80°/sin 80°)* (1)

= (cos 10°*cos 80°)(cos 20°*cos 70°) / (sin 10°*sin 80°)(sin 20°*sin 70°)

= (1/2*(cos60°+cos90°)*1/2(cos50°+cos90°))/(1/2*(cos60°-cos90°)*1/2(cos50°-cos90°))    ... cos90° = 0     cos60° = 1/2

= (1/8*cos50°) / (1/8*cos50°)

Rewrite the equation below so that it does not have fractions

2/3x-5=3/4

Answers

Answer:

Step-by-step explanation:

The best way to do this problem is to find the lowest common denominator.

2/3 : 3*2/(3*3)

3/4 : 3*3 / 3*4

Notice what you have done. You have multiplied both denominators by something that gets rid of the denominators, or will when you multiply by 4 * 3 = 12

So multiply the equation by 12

(2/3 x- 5  = 3/4 ) 12

8x - 60 = 9                                 Add 60 to both sides

8x - 60 = 9                                 Combine

8x = 69                                       Divide by 8

x = 69/8

x = 8  5/8

The person is 5 feet tall when his shadow is 6 feet long.

What is Proportion?

In general, the term "proportion" refers to a part, share, or amount that is compared to a total.

According to the concept of proportion, two ratios are in proportion when they are equal.

A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.

Given:

A person is standing 24 feet away from a street light that is 25 feet tall.

let the height of person be x when its height of shadow is 6 feet.

Using Proportion

x/ 6 = 25 / 30

30x =150

x= 150/ 30

x= 5 feet

Hence, the height of the person is 5 feet.

Find the surface area of the square pyramid. Round your answer to the nearest hundredth.
A. 175.42
B. 176.42
C. 185.42
D. 192.42

Answers

Answer:

175.42

Step-by-step explanation:

 

surface area of square pyramid is given by:

Area= s^2 + 2(s)(l)

where s is the base and l is the slant height

in given problem, slant height l is not given, so by using Pythagoras theorem finding l:

c^2= a^2 + b^2

    =  8^2 + 4^2

    = 48.49

c     = 6.96348

Now putting values of s=8 and l= 6.96 in first formula

Area= 8^2 + 2(8)(6.96)

     =  64 + 111.41

     = 175.42

What is the slope and y intercept I’m really new to this and need help

Answers

Answer:

The y intercept is -1 and the slope is 4/1

Step-by-step explanation:

When you are trying to find the y-intercept, you look at where the line crosses over the y axis. In this case it was at -1.

The slope indicates how many units it is going up/down or left/right. In this case, the distance between each point is up 4, and right 1. so the slope would be 4/1.

Step-by-step explanation:

#3

Given function

f(x) = 2x + 3

a) Complete the table. Find the values of f(x) or y:

x = -1 ⇒ f(-1) = 2(-1) + 3 = -2 + 3 = 1x = 0 ⇒ f(0) = 2(0) + 3 = 0 + 3 = 3x = 1 ⇒ f(1) = 2(1) + 3 = 2 + 3 = 5

b) Plot the points:

(-1, 1), (0, 3), (1, 5)

c. The domain the the set of x- values. Since we connect the points, the domain covers the interval between the endpoints:

Domain: {x | -1 ≤ x ≤ 1}

#4

a) The domain is the set of x- values (first number in ordered pairs):

Domain: {x | x = -3, -2, 0, 2, 3}

The range is the set of y- values (second in pairs):

Range: {y | y = -3 , -1, 1 } (note, repeats are counted as same)

b) Graph by plotting the points:

(-3, -3), (-2, -1), (0, 1), (2, -1), 3, -3)

c) The graph is NOT linear as you don't get a straight line if you connect the points
