Answer:
134inches
Step-by-step explanation:
Convert 2feet to inches
1foot= 12 inches
2feet= 12x2inches
=24inches
24inches is to 1 birdhouse
24inches x 6 equals six birdhouses
134inches
Answer:
He will need 162 inches
Step-by-step explanation:
6×2ft is 12 feet. Convert ft into inches for every 1 foot you have 12 inches. A total of 144in. Now multiply 6×3in which equals 18in. Add 144+18=162

5x2 – 168 = -60x + 12
Answer:
5x2 – 168 = -60x + 12
5x*2 – 156 = -60x

Answer:
[tex](x+6)^{2}[/tex] = 51
Step-by-step explanation:
5x2 – 168 = -60x + 12
5x2 + 60 x – 180 = 0
[tex]x^{2}[/tex] + 12 x – 15 = 0
[tex]x^{2}[/tex] + 12 x = 15
+ 36 + 36
[tex]x^{2}[/tex] + 12 x + 36 = 51
[tex](x+6)^{2}[/tex] = 51
[tex]\sqrt{(x+6)^{2} }[/tex] = [tex]\sqrt{51}[/tex]
x + 6 = [tex]\sqrt{51}[/tex]
x = -6 ± [tex]\sqrt{51}[/tex]
Keller performed the work below to express the polynomial in factored form:
r(x) = x4 – 8x2 – 9
r(x) = (x2 + 1)(x2 – 9)
(x) = (x + 1)(x – 1)(x + 3)(x – 3)
Explain the error he made and complete the factorization correctly.
Answer:
He made the following mistake, he assumed that polynomial [tex](x^{2}+1) = (x^{2}-1)[/tex], having for granted that [tex]x^{2}+1[/tex] has two real roots, instead of two complex roots.

He made the following mistake, he assumed that polynomial [tex](x^{2}+1) = (x^{2}-1)[/tex], having for granted that [tex]x^{2}+1[/tex] has two real roots, instead of two complex roots. The true factorized form of the fourth grade polynomial is:
[tex]r(x) = (x^{2}+1)\cdot (x^{2}-9)[/tex]

11) Write the explicit formula
for the sequence below and
use it to find the 47th term:
-3, 5, 13, 21,...
Answer:
365
Step-by-step explanation:
tn = t1 + (n - 1)(d)
t(47) = -3 + (47 - 1)(8)
t(47) = -3 + (46)(8)
t(47) = -3 + 368
t(47) = 365

Answer:
how do I do another question
Answer:
6 seconds
Step-by-step explanation:
Start by assigning x to value you are trying to find - in this case, the number of seconds until Luigi catches up with Mario.
After x seconds, the distance Luigi has traveled will be the same as the distance Mario has traveled plus 90, since Mario is 90 meters ahead of Luigi.
So our equation is 50x = 35x + 90
Subtracting 35x from both sides: 15x = 90
Dividing both sides by 15: x = 6
So Luigi will catch up with Mario in 6 seconds.

plzx solve it with steps....
how many terms of the A P -6,11/2,-5......are needed to give the sum -25??
plzx give me all the steps....!!
I think the second number is supposed to be negative, -11/2 = -5.5, because otherwise the sequence is not arithmetic.
The n-th term of the sequence, starting with n = 1, is then
-6 + 0.5 (n - 1) = 0.5n - 6.5
and we want to find the number N such that
[tex]\displaystyle\sum_{n=1}^N(0.5n-6.5)=-25[/tex]
We have
[tex]\displaystyle\sum_{n=1}^N(0.5n-6.5) = 0.5\sum_{n=1}^Nn-6.5\sum_{n=1}^N1\\ = 0.5\times\frac{N(N+1)}2 - 6.5N \\= 0.25N^2-6.25N = -25[/tex]
Solve for N :
0.25 N ² - 6.25N + 25 = 0
N ² - 25N + 100 = 0
(N - 20) (N - 5) = 0
N = 20 or N = 5
The function h is defined by h (x) = 3x2 + 7.
Find h(5x).
h (5x) = ?
Answer:
h(5x) = 75x² + 7
Step-by-step explanation:
h(x) = 3x² + 7
h(5x) = 3(5x)² + 7
h(5x) = 3(25x²) + 7
h(5x) = 75x² + 7
[tex]h(5x) = 75x^2 + 7[/tex]
To find h(5x), you simply need to substitute 5x in place of x in the function [tex]h(x) = 3x^2 + 7[/tex] and then simplify the expression.
[tex]h(x) = 3x^2 + 7[/tex]
Now, replace x with [tex]5x: h(5x) = 3(5x)^2 + 7[/tex]
Simplify: [tex]h(5x) = 3(25x^2) + 7[/tex]
Now, calculate [tex]3 * 25: h(5x) = 75x^2 + 7[/tex]
So, [tex]h(5x) = 75x^2 + 7[/tex]

Given the function f(x) = 0.5|x – 4| – 3, for what values of x is f(x) = 7?
x = –24, x = 16
x = –16, x = 24
x = –1, x = 9
x = 1, x = –9
Answer:
x = - 16, x = 24
Step-by-step explanation:
Given f(x) = 7 then equate f(x) to 7
0.5 | x - 4 | - 3 = 7 ( add 3 to both sides )
0.5 | x - 4 | = 10 ( divide both sides by 0.5 )
| x - 4 | = 20
The expression inside the absolute value bars can be positive or negative, so
x - 4 = 20 ( add 4 to both sides )
x = 24
OR
- (x - 4) = 20
- x + 4 = 20 ( subtract 4 from both sides )
- x = 16 ( multiply both sides by - 1 )
x = - 16

Triangles J K L and X Y Z are shown. The length of side J is 3, the length of side K is 6, and the length of side L is 4. The length of side X is 4, the length of side Y is 4, and the length of side Z is 5.
Classify each of the triangles as acute, obtuse, or right.
Triangle JKL is
triangle.
Triangle XYZ is
triangle.
Answer:
The answer is below
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. Types of triangles are acute, scalene, obtuse, equilateral, isosceles and right angled triangle.
For a right angled triangle, the square of the longest side (hypotenuse) is equal to the sum of the square of the remaining two sides.
For an obtuse triangle, the square of the longest side is greater than the sum of the square of the remaining two sides.
For an acute triangle, the square of the longest side is less than the sum of the square of the remaining two sides.
In triangle JKL:
J² + L² = 3² + 4² = 25
K² = 6² = 36 > 25 (J² + L²)
Hence triangle JKL is an obtuse triangle
In triangle XYZ:
X² + Y² = 4² + 4² = 32
Z² = 5² = 25 < 32 (X² + Y²)
Hence triangle XYZ is an acute triangle.
Answer:
obtuse & acute

Write the complement of (90° - a)
Answer:
The complement is ‘a’
Step-by-step explanation:
Mathematically, when two angles are complementary, or said to be a complement of each other, when added, they equal 90 degrees
So, by subtracting the above from 90 degrees, we have its complement
So, we have this as;
90 - (90-a)
= 90 - 90 + a = a

An investment of 100,000 AED increases at a rate of 16% per year. What is
the value of the investment after 20 years? Give your answer to 2 decimal
places
Answer:
1,946,075.95 AED
Step-by-step explanation:
Firstly, we write the general formula for an exponential increase as follows;
V(t) = A( 1 + r)^t
where V(t) is the value after some number of years t
A is the investment amount which is 100,000 AED
r is the rate of increase which is 16% = 16/100 = 0.16
t is the number of years which is 20
substituting these values;
V(20) = 100,000( 1 + 0.16)^20
V(20) = 100,000(1.16)^20
V(20) = 1,946,075.95 AED

Answer:
α = 27.9794744° ≈ 28.0 m (nearest tenth)
Step-by-step explanation:
Step 1:
Opposite (O) = 42.5 (the side opposite to the reference angle, α)
Adjacent (A) = 80
Hypotenuse (H) = the longest side opposite to the right angle
2. We are given the adjacent (A) and opposite (O) lengths, we would use TOA. Which is:
Tan α = Opp/Adj
Plug in the values
Tan α = 42.5/80
3. Make α stand alone
α = [tex] tan^{-1}(\frac{42.5}{80}) [/tex]
4. α = 27.9794744° ≈ 28.0 m (nearest tenth)
what are the domain and range of the function on the graph?
Answer:
The domain: All real numbers.
The range: y>0
Step-by-step explanation:
Domain means all possible x values, and by looking at the graph it covers all real numbers.
Range means all possible y values, and since the x axis is a horizontal asyntope, the graph will never touch the x axis, which is why the range is y>0.

The sum of the measures of the angles of a quadrilateral is 360 degress. Quadrilateral JKLM has one right angle. Use the angles relationships and measure given below to find the measure of angle k
Answer:
Measure Of Angle K is 82*
Step-by-step explanation:
According To Question, We Have Given
A Quadrilateral JKLM, We Know Sum Of All The Angles Of Quadrilateral Is 360* .
Thus
∠JKL=90*
∠KLM= 180* - 110* = 70* ( Find Diagram In Attachment )
∠MJK=118* (Alternative Opposite Angle)
Now We Have To Find The Value Of ∠LKJ.
∠K = 360* - (∠MJK+∠KLM+JKL)
∠K = 360* - (118* + 70* + 90*)
∠K = 360* - 278*
∠K = 82*
