To repair a roof that is 12 feet high, Mr. Callahan leans a 13-foot ladder against the side of the building. To reach the roof, how far away from the building should he place the base of the ladder
Answer:
5 feet away
Step-by-step explanation:
It is a Pythagorean Triple.
The hypotenuse is 13 feet and one of the sides is 12 feet. To find the length of the base, use the Pythagorean Theorem.
13^2=12^2+c^2
169=144+c^2
c^=25

Which phrase best describes the translation from the graph y = (x + 2)2 to the graph of y = x2 + 3?
2 units left and 3 units up
2 units left and 3 units down
2 units right and 3 units up
2 units right and 3 units down
Answer: 2 units left and 3 units up
Step-by-step explanation:
The correct phrase is option c that is the translation in graph is 2 units right and 3 units up.
What do you mean by translation of a graph ?
The modification of an existing graph or graphed equation to create a different version of the following graph is known as translation.
We know that the translation of any graph or a function meant changing the position from one to another.
It is given that the two functions are :
y = (x + 2)²
y = x² + 3
Let's check that in what way the first function is translated to second function.
So , the first function can be written as :
y = (x + 2 - 2)²
or
y = x²
Here , the function is translated by 2 units right.
Now , if we add 3 to the above function we get :
y = x² + 3
Here , the function is translated by 3 units up.
Therefore , the correct phrase is option c that is the translation in graph is 2 units right and 3 units up.

circle of radius 4 units so that they don't overlap?
Answer:
You can fit 11 circles
There are 3 circles of radius 1 unit can you fit inside a circle of radius 4 units.
What is Circle?
The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
Given that;
The circle is shown with radius 4 units.
Now,
Since, The circle is shown with radius 4 units.
Cleary, 4 = 1 + 1 +1 + 1
So, We get 4 circle of radius 1 unit can you fit inside a circle of radius 4 units.
But we find the circle that they don't overlap.
Hence, There are 3 circles of radius 1 unit can you fit inside a circle of radius 4 units.

There were 324 adults surveyed. Among the participants, the mean number of hours of sleep each night was 7. 5 and the standard deviation was 1. 6. The margin of error, assuming a 95% confidence level, is approximately. Round to the nearest hundredth.
The margin of error for 324 adults surveyed with 1.6 standard deviations is 0.1742.
What is the margin of error?The margin of error can be defined as the amount of random sampling error in the results of a survey. It is given by the formula,
[tex]\text{MOE}_{\gamma}=z_{\gamma} \times \sqrt{\frac{\sigma^{2}}{n}}[/tex]
[tex]\text{MOE}[/tex] = margin of error
[tex]\gamma[/tex] = confidence level
[tex]z_{\gamma}[/tex] = quantile
σ = standard deviation
n = sample size
As it is given that the sample size of the survey is 324, while the standard deviation of the survey is 1.6.
We know that the value of the z for 95% confidence interval is 1.96. Therefore, using the formula of the standard of error we can write it as,
[tex]\text{MOE}_{\gamma}=z_{\gamma} \times \sqrt{\dfrac{\sigma^{2}}{n}}\\\\\text{MOE}_{\gamma}=1.96 \times \sqrt{\dfrac{1.6^{2}}{324}}\\\\\text{MOE}_{\gamma}=0.1742[/tex]
Hence, the margin of error for 324 adults surveyed with 1.6 standard deviations is 0.1742.

Write a numerical expression that represents the area Sabrina painted the second weekend. Using this numerical expression, find the area that Sabrina painted the second weekend.
Step-by-step explanation:
she painted half of the still to be painted area.
after the first weekend there were 800 of 1600 ft² painted, and therefore 1600 - 800 = 800 ft² left to be painted.
on the second weekend she then painted half of that :
800 / 2.
that means she painted 800/2 = 400 ft², and that left 800 - 400 = 400 ft² to be painted on the following weekends.
if we look in detail, we find the starting 800 ft² of the second weekend are already the result of the first weekend.
800 = 1600 / 2
so,
800 / 2 = 1600 / 2 / 2 = 1600 / 2² = 1600 / 4.
and the same principle goes on weekend after weekend.
therefore, the expression for the nth weekend could be
1600 × (1/2)^n ft²
that means, she painted
on the 1st weekend : 1600 × 1/2 = 800 ft²
on the 2nd weekend : 1600 × 1/4 = 400 ft²
on the 3rd weekend : 1600 × 1/8 = 200 ft²
on the 4th weekend : 1600 × 1/16 = 100 ft²
...
that also means : she will never be finished, as she always paints only half of what is still left open, and that leaves always some part open. it will be tinier and tinier over time, but never 0.

Find the measure of each angle in Triangle ABC. m∠a=(50−x)°m∠b=(9x−40)°m∠c=90°
Answer:
40°
50°
90°
Step-by-step explanation:
sum of angle in a triangle is= 180°
(50-x)° + (9x-40)° + 90° = 180°
50-x+9x-40 + 90 = 180
50- 40 +90 -x+9x =180
100 + 8x = 180
8x = 180 -100
8x = 80
x = 80/8 =10
x = 10°
measure of a= (50-x) = 50- 10 = 40°
measure of b = (9x-40)= 90- 40= 50°
measure of c = 90°
If the length of the side of a square is 11cm. Then find its area and also find the total length of its boundary.
Answer:
[tex]\displaystyle 44\:cm. = P \\ 121\:cm.^2 = A[/tex]
Step-by-step explanation:
All angles and edges are congruent in a square, so first, find the total boundary by multiplying the length of the edge by 4:
[tex]\displaystyle 4l = P \\ 4[11] = P \\ \\ 44 = P[/tex]
Now, for the area, you square the length of the edge:
[tex]\displaystyle s^2 = A \\ 11^2 = A \\ \\ 121 = A[/tex]

The number of penguins on an iceberg is
modeled by the equation P(t) = 24(1.231)^t
where t is years since 2010. If
the iceberg has a population of 70 penguins it
will begin to sink and the penguins will have to
find a new home. In
what year are the penguins going to find a new home?
The function of the number of penguins is an exponential function
The penguins are going to find a new home in 2015
How to determine the yearThe equation of the function is given as:
[tex]P(t) = 24(1.231)^t[/tex]
When there are 70 penguins, the equation becomes
[tex]24(1.231)^t =70[/tex]
Divide both sides by 24
[tex]1.231^t =2.917[/tex]
Take the logarithm of both sides
[tex]t\log(1.231) =\log(2.917)[/tex]
Divide both sides by log(1.231)
[tex]t =5[/tex]
The time is 5 years from 2010.
So, we have
Year = 2010 + 5
Year = 2015
Hence, the penguins are going to find a new home in 2015
