A ladder is leaning against a wall. The top of a ladder is 5m off the floor and the base of the ladder is 1m away from the wall. How long is the ladder? Give your answer to one decimal place.
Answer:
The ladder is 5.09 m long
Step-by-step explanation:
Given that,
The height of the wall, P = 5 m
The base of the ladder is 1 m away from the wall.
We need to find the length of the ladder. Let it is H. We can solve it using the Pythagoras theorem. It can be given by :
[tex]H^2=P^2+B^2\\\\H^2=5^2+1^2\\\\H^2=25+1\\\\H=\sqrt{26} \\\\H=5.09\ m[/tex]
So, the ladder is 5.09 m long.

Given a circle with radius of 18 m, what is the diameter?
Answer:
d=36m
Step-by-step explanation:
d=2r=2·18=36m
Answer:
Your in luck! I'm actually learning this right now!
Step-by-step explanation:
d = 2r so basically your diameter is your radius times 2! So 18 x 2 = 36 so the answer should be 36 hope this helps!

Which polygon has interior angles whose measures sum to 720°?
hexagon
nonagon
heptagon
octagon
Answer:
Hexagon
Step-by-step explanation:
Explanation: The sum of the interior angles of a hexagon must equal 720 degrees. Because the hexagon is regular, all of the interior angles will have the same measure. A hexagon has six sides and six interior angles.

Multiple choice answer
Answer:
C. 9.24
Step-by-step explanation:
x is the height here, looking at the triangle.
To find x, however, we first have to find the hypotenuse. To formula for that is b (side we know)/cos(α) (angle we know). Substitute b for 6, and α for 57.
6/cos(57) would equal about 11.0647.
Now back to x. To figure that out, subtract 6² from 11.01647². Then, find the square root of that.
x = √11.01647² - 6²
x = √121.3626112609 - 36
x = √85.3626112609
x = 9.23918888544335
x ≈ 9.24, so C is the answer.

What is the average rate of change of f(x) = 2x^2 - x - 4 over the interval -4 < x < 2?
The average rate of change of f(x) = 2x^2 - x - 4 over the interval -4 < x < 2 is -5.
To find the average rate of change of a function over an interval, we need to calculate the difference in the function values at the endpoints of the interval and divide it by the difference in the x-values.
The given function is f(x) = 2x^2 - x - 4.
Let's calculate the function values at the endpoints of the interval: -4 and 2.
For x = -4:
f(-4) = 2(-4)^2 - (-4) - 4 = 32 + 4 - 4 = 32.
For x = 2:
f(2) = 2(2)^2 - 2 - 4 = 8 - 2 - 4 = 2.
Now, we can calculate the difference in the function values: f(2) - f(-4) = 2 - 32 = -30.
Next, we calculate the difference in the x-values: 2 - (-4) = 6.
Finally, we can calculate the average rate of change by dividing the difference in the function values by the difference in the x-values:
Average Rate of Change = (f(2) - f(-4)) / (2 - (-4)) = -30 / 6 = -5.

Gethyn drinks 48 fluid ounces of water in one day. He needs to drink 8 cups in total. How many more cups does he need to drink?
A) 2 cups
B) 6 cups
C) 384 cups
D) 768 cups
Answer:A
Step-by-step explanation:1 cup is equal to 8 fluid ounces so 48/8=6 and since he needs to drink 8 cups of water the answer is 2 more.
The number of cups of water Gethyn need to drink more is 2 cups. Therefore, option A is the correct answer.
What is metric conversion?Metric Conversion refers to the conversion of the given units to desired units for any quantity to be measured.
Given that, Gethyn drinks 48 fluid ounces of water in one day.
We know that, 1 ounce = 0.125 cups
Here, 48 fluid ounces = 48×0.125
= 6 cups
Number of cups of fluid = 8-6
= 2 cups
Therefore, option A is the correct answer.

Answer:
1. Not similar
2. Similar, ABC is similar to FED by SSS
Step-by-step explanation:
1. Not similar.
The interior angles of a triangle always have to add up to 180, and since the first triangle has angles 30 degrees and 90 degrees, you know the third angle will have to be 180 - 30 - 90 = 60 degrees.
The second triangle's third angle will have to be 50 degrees because 180 - 90 - 40 = 50 degrees.
Since the three angles of the triangle are not the same, they are not similar.
2. Similar, ABC is similar to FED by the SSS triangle similarity postulate.
First, AB is similar to FE because AB = 15 and FE = 5, so the scale factor is 3
Next, BC is similar to ED because BC = 9 and ED = 3, so the scale factor for these sides is also 3
Lastly, CA is similar to DF because CA = 12 and DF = 4, so the scal factor for this is also 3.
Since the scale factor for all of the sides is 3, these two triangles are similar.
