Answer:
4.41
Step-by-step explanation:
The sides of interest in this right triangle are the hypotenuse and the side adjacent to the given angle. The relevant trig relation is ...
Cos = Adjacent/Hypotenuse
cos(25°) = 4/AB
Multiplying by AB and dividing by cos(25°), we get ...
AB = 4/cos(25°)
AB ≈ 4.41 . . . . units
The fire logs in a backyard are arranged so that each row has 5 fewer logs than the row below it. If the first row has 58 logs, how many logs are in the 6th row?
a
28
b
33
c
38
d
53
Using arithmetic progression, number of logs in 6th row are 33.
How to find no. of logs are in the 6th row?We can use the information that each row has 5 fewer logs than the row below it to create a sequence of the number of logs in each row. Let's call the number of logs in the first row "a" (which we know is 58 logs). Then, the number of logs in the second row will be "a - 5", the number of logs in the third row will be "(a - 5) - 5" or "a - 10", and so on.
So, we have the sequence of the number of logs in each row as:
a, a - 5, a - 10, a - 15, a - 20, ...
To find the number of logs in the 6th row, we need to find the 6th term in this sequence. We can use the formula for the nth term of an arithmetic sequence:
an = a₁ + (n - 1)d
where an is the nth term, a1 is the first term, n is the number of the term we want to find, and d is the common difference between terms (which is -5 in this case, since each row has 5 fewer logs than the row below it).
Substituting the given values, we get:
a₆ = a₁ + (6 - 1)(-5)
= a - 25
So, the number of logs in the 6th row is a - 25. Since we know that a is 58 logs, we can substitute and simplify:
a - 25 = 58 - 25 = 33
Therefore, the answer is (b) 33.

A sum of money is to be divided among Anthea, Barry and Carol in the ratio 2:5:1
respectively. If Barry got $200 more than Carol, calculate:
The sum of money?
Answer:
$400
Step-by-step explanation:
Lets money that Anthea got be 2x
than Barry's money be 5x and Carol's be x
Barry got $200 more than Carol
This means that 5x is 200 more than x
5x = x + 200
4x = 200
x = 50
The sum of money is 2x + 5x + x
so this is 8x
8x = 50 * 8 = 400

What are inequalities in math?In mathematics, a relationship between two expressions or values that are not equal to each other is called 'inequality.
How to solve inequality?When resolving an inequality, you can do one of the following: • Add the same amount to each side; Subtract the same amount from each side; • Multiply or divide each side by the same positive amount. You must flip the inequality sign if you multiply or divide either side by a negative number.
Considering that there are 9 different condiments to pick from
Using the relation, one may determine how many different ways there are to arrange n items in a list.
Here, n = 9
As a result, there may be created the following number of sandwiches:
The bare minimum of condiments needed to give at least 2000 distinct sandwich options is:
In order to do this,
n = 11
Since the inequality is satisfied by 211, the number of condiments required to provide at least 2000 distinct sandwiches is 11.

Find the area of a circle with a diameter of 10 ft. ( = 3.14)
Answer:
78.5 ft² or25πStep-by-step explanation:
Find the area of a circle with a diameter of 10 ft.
Area of a Circle
A = π × r²
r = diameter : 2
10 : 2 = 5 ft (radius)
A = π × 5²
A = 3.14 * 25
A = 78.5 ft²
Find the solutions of the quadratic equation -9c² +2 +3 = 0.
Given that,
An equation : -9c² +2c +3 = 0
To find,
Find the value of x.
Solution,
We have, -9c² +2c +3 = 0
We can solve it using the formula as follows :
\(x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}\)
Here, a = -9, b = 2 and c =3
Put the values,
\(c=\dfrac{-2\pm \sqrt{(2)^2-4(-9)(3)}}{2(-9)}\\\\c=\dfrac{-2+\sqrt{(2)^{2}-4(-9)(3)}}{2(-9)}, \dfrac{-2-\sqrt{(2)^{2}-4(-9)(3)}}{2(-9)}\\\\c=-0.47, 0.69\)
So, the solution are -0.47 and 0.69.

Describe how p(x)=-f(x)-3 transforms the graph of the parent function f(x)=x^2
.
The transformation of f(x) to p(x) is that (a) the graph is reflected and shifted down
Describing the transformation of f(x) to p(x).From the question, we have the following parameters that can be used in our computation:
The functions f(x) and g(x)
In the function equations, we can see that
f(x) = x²
p(x) = -f(x) - 3
So, we have
Vertical Difference = 0 - 3
Evaluate
Vertical Difference = - 3
This means that the transformation of f(x) to p(x) is that f(x) is reflected and shifted down 3 units to p(x).

triangle abc is isosceles what is the length of bc
The length of BC is 40 units
What is isosceles triangle?
An isosceles triangle is one that has two sides of equal length.
The angles opposite to equal sides are equal.
AB=x+17 units
BC=2x-6 units
We were given that the triangle is an isosceles triangle.
This means that these two sides are equal.
We therefore form the equation below and solve for the value of x.
x+17 = 2x-6
x-2x= -6-17
x=23
We substitute this value into the expression for side BC to get ,

We have,
We can simplify the given expression as follows:
(X - Y) 5 ÷ 8 - 1 ÷ 4 (X + Y)
= (5X - 5Y) ÷ 8 - 1 ÷ (4X + 4Y)
[distributing the factors]
= (5X - 5Y) /8 - 1/(4X + 4Y)
[finding a common denominator]
= ((5X - 5Y)(4X + 4Y) - 1)/(4X + 4Y)
= (20X² + 20XY - 20XY - 20Y² - 1) / (4X + 4Y)
= (20X² - 20Y² - 1) / (4X + 4Y)

Step-by-step explanation:
The first thing we want to do is isolate the variable, x² in this case.
We can divide both sides by 9 which yields the equation x²=\(\frac{4}{9}\).
Then we can take the square root of both sides, x=2/3.
Note: When the exponent is an even number both positive and negative x values will yield the same positive answer, so x=±2/3

Acrylic bone cement is sometimes used in hip and knee replacements to secure an artificial joint in place. The force required to break an acrylic bone cement bond was measured for seven specimens, and the resulting mean and standard deviation were 306.07 newtons and 41.96 newtons, respectively. Assuming that it is reasonable to believe that breaking force has a distribution that is approximately normal, use a 95% confidence interval to estimate the mean breaking force for acrylic bone cement. (Round your answers to three decimal places.)
The required 95% confidence interval for the mean breaking force of acrylic bone cement is approximately 267.29 to 344.85 newtons.
Find the critical value (t*) for a 95% confidence level and (n - 1) degrees of freedom.
The degrees of freedom (df) is equal to the sample size minus 1 (df = 7 - 1 = 6). From a t-table or statistical software, the critical value for a 95% confidence level and df = 6 is approximately 2.447.
Calculate the standard error of the mean (SE).
The standard error of the mean is given by SE = (sample standard deviation) / sqrt(sample size).
\(SE =\dfrac{41.96}{\sqrt{7}}\)
≈ 15.85
Calculate the margin of error (MoE).
The margin of error is MoE = (t*) * SE.
MoE ≈ 2.447 * 15.85
≈ 38.78
Calculate the confidence interval.
The confidence interval is given by: Mean ± MoE.
Mean ± MoE ≈ 306.07 ± 38.78
Calculate the lower and upper bounds of the confidence interval.
Lower bound ≈ 306.07 - 38.78
= 267.29
Upper bound ≈ 306.07 + 38.78
= 344.85
Therefore, the 95% confidence interval for the mean breaking force of acrylic bone cement is approximately 267.29 to 344.85 newtons.

A construction crew needs to pave a road that is 202 miles long. The crew paves 9 miles of the road each day. The length, L (In miles), that is left to be pavedafter d days is given by the following functionL (D)=202 -9DAnswer the following questions.(a) if 130 miles of the road is left to be paved, how many days has the crew beenpaving the road?1 days(b) How many miles of the road does the crew have left to pave after 13 days?
a) The crew has been paving the road for 8 days
b) The crew has 85 miles left to pave after 13 days
Explanation:The function representing the length, L (In miles), that is left to be paved
after D days is given as:
L(D) = 202 - 9D
a) If 130 miles of the road is left to be paved
L(D) = 130
Substitute L(D) = 130 into the equation L(D) = 202 - 9D and solve for D
130 = 202 - 9D
9D = 202 - 130
9D = 72
D = 72/9
D = 8
The crew has been paving the road for 8 days
b) The number of miles the crew have left to pave after 13 days
D = 13
L(D) = 202 - 9D
L(13) = 202 - 9(13)
L(13) = 85
The crew has 85 miles left to pave after 13 days 2
