Proper angle for a ladder is about 75° from the ground. Suppose you have a 10 foot ladder. How far from the house should you place the base of the latter? Round to the nearest hundredth
Answer:
The base of the ladder is 2.58 m.
Step-by-step explanation:
Given that,
The angle of elevation for a ladder from the ground is 75°.
The length of a ladder, H = 10 foot
We need to find the distance from the house should you place the base of the latter. Let the base of the ladder is b. Using trigonometry,
[tex]\cos\theta=\dfrac{B}{H}\\\\B=H\times \cos\theta\\\\B=10\times \cos(75)\\\\B=2.58\ m[/tex]
So, the base of the ladder is 2.58 m.
What is the length of the radius of a circle whose circumference is 125.6 feet? Use 3.14 for Pi.
Answer:
Hello! answer: 20
Step-by-step explanation:
circumference is just diameter × pi so If we do circumference ÷ pi we will get our diameter so
125.6 ÷ 3.14 = 40 But remember diameter is just twice the radius so all we have to do is divide by 2 to get our radius so
40 ÷ 2 = 20 So 20 is the radius Hope this helps!
Answer:
the answer is 20 feet
Step-by-step explanation:
divide the circumference by 3.14 gives you the diameter then divide the diameter by 2 to get the radius.

Answer:
x = 35
y = 95
Step-by-step explanation:
(For y) The measure of a line is 180 degress. 180 - 95 - 50 = 35.
(For x) The measure of a triangle is 180 degress. 180 - 50 - 35 = 95.
Answer:
x = 85, y = 45
Step-by-step explanation:
solving for x:
180 - 95 = 85
solving for y:
85 + 50 = 135
180 - 135 = 45

Answer:
x = 1.19258 and x = −4.19258
Step-by-step explanation:
The given equation is :
[tex]x^2+3x-5=0[/tex]
Keep x terms on the left and move the constant to the right side by adding it on both sides.
[tex]x^2+3x=5[/tex]
Take half of the x term and square it.
[tex](3\times \dfrac{1}{2})^2=\dfrac{9}{4}[/tex]
then add the result to both sides
[tex]x^2+3x+\dfrac{9}{4}=5+\dfrac{9}{4}\\\\(x+\dfrac{3}{2})^2=\dfrac{29}{4}\\\\(x+\dfrac{3}{2})=\sqrt{\dfrac{29}{4}}\\\\x=\dfrac{-3}{2}+\sqrt{\dfrac{29}{4}}\\\\x=\dfrac{-3}{2}-\sqrt{\dfrac{29}{4}}[/tex]
So,
x = 1.19258 and x = −4.19258
Hence, this is the required solution.

Part A: explain why x coordinates of the points where the graphs of the equations y=4^x and y=2^(x-1) intersect are the solutions of the equation 4^x=2^(x-1). Part B: Make tables to find the solution to 4^x=2^(x-1). Take the integer values of x between -4 and 4. Part C: How can you solve the equation 4^x=2^(x-1) graphically?
9514 1404 393
Explanation:
A. The given equation will have a solution when the value of x makes the left-side expression equal to the right-side expression.
The value of the left-side expression for a given value of x is the y-value of y=4^x. The value of the right-side expression for a given value of x is the y-value of y=2^(x-1). The left-side expression will be equal to the right-side expression for a given value of x when the graph of y=4^x and the graph of y=2^(x-1) have the same y-value. That is, the graphs will be of the same point for that x-value. That is what we mean when we say the curves will intersect at that point.
The x-coordinate of the point of intersection is the value that makes the expressions equal, hence it is the solution to the equation.
__
B. The tables are included in the first attachment. We have used f(x) to represent the left-side expression, and g(x) to represent the right-side expression.
__
C. As described in Part A, the graphs will cross at the solution point. Hence the equation can be solved graphically by graphing the left-side expression and the right-side expression and seeing where the graphs cross. (That is at the point (-1, 0.25) on the attached graph.)
Alternate graphical method
The solution can also be found graphically by graphing the difference of the expressions: y = 4^x -2^(x-1). This difference will be zero at the value of x that makes the two expressions equal. That is, the x-intercept of the graph of this difference will be the solution value. The second attachment shows this sort of graphical solution. (It works nicely because many graphing calculators will display the value of the x-intercept.)

There are 220 ways to choose the paintings.
What is combination in mathematics?"Combination determines the number of possible arrangements in a collection of items where the order of the selection does not matter."
Formula for combination:[tex]^{n}C_r=\frac{n!}{r!(n-r)!}[/tex]
For given example,
There are 12 paintings at an art show.
⇒ n = 12
Three of them are chosen randomly to display in the gallery window.
⇒ r = 3
So, using the formula for combination, the number of possible ways to choose the paintings would be,
[tex]\Rightarrow~ ^{n}C_r=\frac{n!}{r!(n-r)!}\\\\\Rightarrow~ ^{12}C_3=\frac{12!}{3!(12-3)!}\\\\\Rightarrow~ ^{12}C_3=\frac{12!}{3!\times 9!}\\\\\Rightarrow~^{12}C_3=220[/tex]
Therefore, there are 220 ways to choose the paintings.

Six less than the product of a number n and 1/5 is no more than 99
Answer:
(n * ⅕) - 6 ≤ 99
Step-by-step explanation:
Translating the word problem into an algebraic expression, we have;
(n * ⅕) - 6 ≤ 99
Opening the bracket, we have;
n/5 - 6 ≤ 99
Rearranging the equation, we have;
n/5 ≤ 99 + 6
n/5 ≤ 105
Multiplying both sides by 5, we have;
5 * n/5 ≤ 105 * 5
n ≤ 525
If each cube in the rectangular prism measures 1 cubic foot, what is the volume of the prism?
A.
8 cubic ft
B.
6 cubic ft
C.
11 cubic ft
D.
7 cubic ft
Answer:
6 cubic feet
Step-by-step explanation:
Since each cube represents 1 cubic foot
volume of the prism = number of cubes * volume of 1 cube
Given
number of cubes = 6
volume of 1 cube = 1cubic foot
Substitute
volume of the prism = 6 * 1
volume of the prism = 6 cubic feet
Can anyone give me some advices for my sis cause she is going to high school soon and I'm worried- even tho she is older then me, she is Autism and ofc I'm worried-

Advice;
Talk to her, let her know of the things she could be facing, yes we can give her as much advice as needed but it won't stop her from facing other rude teenagers.If she has a temper you guys should come up w coping mechanisms to use during school when she'll be alone. It's good practice to growing up.Ask for a tour around the school, it'll help her be more aware of her surroundings when she starts to attend.If she's nervous about entering a whole different nd new place it's fine, assure her it's going to be okay it'll just be a little adjustment.Advice for you; ( I know it wasn't asked of )
Calm down. Don't stress, I mean I know you're gonna, she's your sister but worrying about her is just gonna be a whole other problem you don't need. She's fine, she'll be fine, you don't want her to see you worry nd make her feel the same way, right?Alright, hope this was helpful! Need a little more insight? Feel free to ask.

To start planning the rooms' floor plans, you draw them each to scale on large sheets of paper. You are going to use the scale 1 foot: 2 inches. That is, 1 foot in real life will be represented by 2 inches on your paper. How many square inches of paper do you need for the bedroom? Enter just the number in the blank below.
Answer:
(/480/) is the answer I just took the test
Step-by-step explanation:
The number of square inches of papar we need for the bedroom is 480.
How are scale drawings formed?For a particular scale drawing, it is already specified that all the measurements' some constant scaled version will be taken. For example, let the scale be K feet to s inches.
Then it means
[tex]\rm 1\: ft : \dfrac{s}{k}\: in.[/tex]
All feet measurements will then be multiplied by s/k to get the drawing's corresponding lengths.
For this case, the scale drawing is converting
1 foot (of real world) : 2 inches (on drawing paper).
Thus, 1 sq. ft area = 2^2 = 4 sq. inch area on paper. (we squared 2, since the square whose sides are 1 ft in real world, will haves sides of 2 inches in drawing, so a side of 2 inches sq. has 4 sq. inch area.)
The area of the floor is 120 sq. ft (some parts are missing in the question statement).
So, as 1 sq. ft : 4 sq. inches on paper,
thus, 120 sq. ft : 120 × 4 = 480 sq. inches area on paper.
Thus, to draw the whole bedroom (which is based on the floor), we need at least 480 sq. inches of paper.
