Find the length of side x in simplest radical form with a rational denominator.
Answers
Answer:
x=2√5
Step-by-step explanation:
1st method:
sin(30)=opposite/hypotenuse=√5/x
sin(30)x=√5
x=√5/sin(30)
x=2√5
2nd method:
cos(60)=adjacent/hypotenuse=√5/x
cos(60)x=√5
x=√5/cos(60)
x=2√5
3rd method:
This is a 30-60-90 triangle, so we can multiply the short side, √5, by 2, to get x=2√5

The angle of elevation of the top of a tower from two points 121 m and 144 m away from the foot of the tower on th same side are found to be complementary. find the height of the tower.
Answers
Answer:
132 m
Step-by-step explanation:
Refer to attachment for figure.
In smaller triangle with angle theta , we have ,
⇒ tanθ = p/b
⇒ tanθ = h/121m
⇒ tanθ = h/121 m
In triangle with angle 90-∅
⇒ tan(90-θ) = p/b
⇒ cot θ = h/144 m
Multiplying these two ,
=> tanθ . cotθ = h/121 m × h/144m
=> 1 = h²/ (121 m × 144m )
=> h² = 121m × 144m
=> h= √ ( 121m × 144m)
=> h = 11m × 12m
=> h = 132 m

Answer:
467
Step-by-step explanation:
Determine the percentage of those sampled whose favourite season is fall
(18/70) x 100 = 25.7%
the sample is representative of the population of students. So, 25.7% of the students would like fall
number of students at Franklin High School whose favourite season is fall = 25.7% x 1816 = 466.7 students
rounding off to the nearest whole number gives 467

How do I solve this arithmetic sequence?

In other words, a1 = 13, then
a2 = a1 + 4 = 13 + 4 = 17
a3 = a2 + 4 = 17 + 4 = 21
And so on.
There is a formula to find larger terms.
Since a2 = a1 + 4
a3 = a2 + 4
= (a1 + 4) + 4
= a1 + 2*4
a4 = a3 + 4
= a1 + 2*4 + 4
= a1 + 3*4
And so on, notice the pattern:
an = a1 + (n-1)*d
a6 = a1 + 5*d = 13 + 5*4 = 13 + 20 = 33
Answer:
The 6ᵗʰ term of this sequence is 82
Step-by-step explanation:
Here,
First Term = a₁ = 13
Common Difference = (d) = 4
Now, For 6ᵗʰ term, n = 16
aₙ = a + (n - 1)d
a₆ = 13 + (6 - 1) × 4
a₆ = 13 + 5 × 4
a₆ = 13 + 20
a₆ = 33
Thus, The 6ᵗʰ term of this sequence is 33

Kendra spends $15 buying fabric to make baby blankets.She can make 4 blankets from one pice of fabric.If she sells the blankets for $10 each٫what is her profit?
Answers
Answer:
her profit is $25
Step-by-step explanation:
Given that
She spends $15 for purchasing fabric so that she make the baby blankets
And, she can make 4 blankets from one piece of fabric
Now she sold the blankets for 10 each
So we need to find out the profit
As we know that
Profit = Selling cost - purchasing cost
= (4 × $10) - $15
= 40 - $$5
= $25
hence, her profit is $25

One standard form of the equation of a straight line is
y = mx + c where m = the slope and c = the y-intercept.
Comparing this with y = 3x - 6 we see that:
The slope = 3 and the y-intercept is -6.
The error was in the y-intercept.
#2.
The error is in stating the intercepts
x - intercept is (8, 0) and y-intercept = (0, 2), (NOT (8, 2)).
#3.
The error is in stating the intercepts
x - intercept is (5, 0 and y-intercept = (0, 2).

Answers
Answer:
x=1+√3
Step-by-step explanation:
Let's solve your equation step-by-step.
6x^2+6=12x+18
Step 1: Subtract 12x+18 from both sides.
6x^2+6−(12x+18)=12x+18−(12x+18)
6x^2−12x−12=0
For this equation: a=6, b=-12, c=-12
6x^2+−12x+−12=0
Step 2: Use quadratic formula with a=6, b=-12, c=-12.
x=−b±√b2−4ac/2a
x=−(−12)±√(−12)2−4(6)(−12)/2(6)
x=12±√432/12
x=1+√3
