1. Write an equation to determine the height, h, of the building.
Answer: 5^2 +h^2 = 102
2. To the nearest tenth, determine the height of the
building.
Answers
Answer:
8.7 m
Step-by-step explanation:
Hi there!
[tex]5^2+h^2=10^2[/tex]
To find the height of the building, we need to isolate h on one side of the equal sign. We will do this by performing inverse operations to both sides (ex. the inverse of addition is subtraction, the inverse of multiplication is division, etc.)
Firstly, we can simplify both sides by squaring 5 and 10:
[tex]25+h^2=100[/tex]
Now subtract both sides by 25 to cancel it out on the left side and isolate h²:
[tex]25+h^2-25=100-25\\h^2=75[/tex]
Now, take the square root of both sides to isolate h:
[tex]\sqrt{h^2} =\sqrt{75} \\h=8.7[/tex]
Therefore, the height of the building is 8.7 m when rounded to the nearest tenth.
I hope this helps!

Find the exact value of tan 60° in simplest form with a rational denominator.
Answers
Step-by-step explanation:
We need to find the exact value of tan 60° in simplest form with a rational denominator.
We know that, [tex]\tan\theta=\dfrac{\sin \theta}{\cos\theta}[/tex]
Here, [tex]\theta=60^{\circ}[/tex]
So,
[tex]\tan(60)=\dfrac{\sin (60)}{\cos(60)}\\\\=\dfrac{\dfrac{\sqrt3}{2}}{\dfrac{1}{2}}\\\\=1.73\\\\or\\\\=\dfrac{173}{100}[/tex]
Hence, this is the required solution.
how can i solve the following
4x-3=2x+7
Answers
Answer:
x = 5
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x.
Add 3 and subtract 2x from both sides of the equation:
4x (-2x) - 3 (+3) = 2x (-2x) + 7 (+3)
4x - 2x = 7 + 3
2x = 10
Next, isolate the x by dividing 2 from both sides of the equation:
(2x)/2 = (10)/2
x = 10/2
x = 5
5 is your answer for x.

Answer:
x=5
Step-by-step explanation:
4x-3=2x+7
Subtract 2x from each side
4x-2x-3=2x-2x+7
2x -3 = 7
Add 3 to each side
2x-3+3=7+3
2x = 10

y = 2·3^x
Step-by-step explanation:
The shape of the graph appears exponential. The horizontal asymptote appears to be y=0, so there is no vertical offset. The y-intercept seems to be 2 (we can't really read the numbers), and the y-value seems to increase by a factor of 3 for each additional unit of x.
The multiplier is 2, and the base of the exponential factor is 3. That gives us ...

What are the zeros of the quadratic function f(x) = 6x2 + 12x-7?
Answers
Answer:
[tex]f(x) = 6x ^{2} + 12x - 7 \\ x = \frac{ - 6 + \sqrt{78} }{6} \: , - \frac{ - 6 - \sqrt{78} }{6} [/tex]
Given:
The quadratic function is:
[tex]f(x)=6x^2+12x-7[/tex]
To find:
The zeros of the quadratic function.
Solution:
Quadratic formula: If a quadratic equation is [tex]ax^2+bx+c=0[/tex], then zeros of the quadratic equation are:
[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
We have,
[tex]f(x)=6x^2+12x-7[/tex]
For zeros, [tex]f(x)=0[/tex].
[tex]6x^2+12x-7=0[/tex]
Here, [tex]a=6,b=12,c=-7[/tex]. Using quadratic formula, we get
[tex]x=\dfrac{-12\pm \sqrt{(12)^2-4(6)(-7)}}{2(6)}[/tex]
[tex]x=\dfrac{-12\pm \sqrt{144+168}}{12}[/tex]
[tex]x=\dfrac{-12\pm \sqrt{312}}{12}[/tex]
[tex]x=\dfrac{-12\pm 17.6635}{12}[/tex]
Now,
[tex]x=\dfrac{-12+17.6635}{12}[/tex] and [tex]x=\dfrac{-12-17.6635}{12}[/tex]
[tex]x=0.47195833...[/tex] and [tex]x=-2.47195833...[/tex]
[tex]x\approx 0.472[/tex] and [tex]x\approx -2.472[/tex]
Therefore, the zeros of the given quadratic function are 0.472 and -2.472.

The Department of Transportion (DOT) is attempting to determine the proportion of drivers who require all passengers in the car to wear their seatbelt before putting the vehicle in drive. A survey of 114 drivers is performed and 62 people say they will not drive until all passengers in the vehicle are buckled up. To report their finding they want to create a 95% confidence interval. What would be the margin error for this confidence interval?
1) 0.0043
2) 0.0914
3) 0.0086
4) 0.0765
5) 0.0466
Answers
Answer:
2) 0.0914
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is of:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
A survey of 114 drivers is performed and 62 people say they will not drive until all passengers in the vehicle are buckled up.
This means that [tex]n = 114, \pi = \frac{62}{114} = 0.5439[/tex]
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
What would be the margin error for this confidence interval?
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]M = 1.96\sqrt{\frac{0.5439*0.4561}{114}}[/tex]
[tex]M = 0.0914[/tex]
Thus the margin of error is 0.0914, option 2).

Answer:
Angle 2 = 124 degrees
Step-by-step explanation:
Angles 1 and 2 are corresponding angles since the two lines are parallel.
We can put both numbers into an equation.
3x + 25 = 2x + 58
Subtract both sides by 2x which will give:
x + 25 = 58
Now, we can solve for x, which is:
x = 58-25 = 33
Put back x = 33 into angle 2.
Hence, angle 2 is 2*33 + 58 = 124
Answer:
m∠2 = 124 degrees
Step-by-step explanation:
By the definition of "Same Side Corresponding Angles" the 2 angles given are congruent to each other, therefore we can say;
3x + 25 = 2x + 58
x + 25 = 58
x = 58 - 25
x = 33
Now that we have x = 33, we can substitute 33 in for x, in equation given for angle 2 to find it's measure;
∠2 = 2(33) + 58
∠2 = 66 + 58
∠2 = 124
Therefore m∠2 = 124 degrees.

The first term of a G.P are as follows: m, m2 +4, 16m. Find the 5th term.
Answers
Answer:
512
Step-by-step explanation:
To effectively answer the question, let us calculate the value of m. This can be obtained as follow:
m, (m² + 4), 16m
1st term (T₁) = m
2nd term (T₂) = m² + 4
3rd term (T₃) = 16m
Common ratio = T₂/T₁ = T₃/T₂
(m² + 4) / m = 16m / (m² + 4)
Cross multiply
(m² + 4)(m² + 4) = m × 16m
(m² + 4)² = 16m²
Take the square root of both side
√[(m² + 4)²] = √(16m²)
m² + 4 = 4m
Rearrange
m² – 4m + 4 = 0
Solving by Factorisation
m² – 2m – 2m + 4 = 0
m(m – 2) – 2(m – 2) = 0
(m – 2)(m – 2) = 0
(m – 2)² = 0
Take the square root of both side
m – 2 = 0
m = 2
Thus,
1st term (T₁) = m = 2
2nd term (T₂) = m² + 4 = 2² + 4 = 8
3rd term (T₃) = 16m = 16 × 2 = 32
The sequence => m, (m² + 4), 16m
Becomes
2, 8, 32
Finally, we shall determine the 5th term. This can be obtained as follow:
1st term (a) = 2
Common ratio (r) = 2nd / 1st = 8/2 = 4
5th term (T₅) =?
T₅ = ar⁴
T₅ = 2 × (4)⁴
T₅ = 2 × 256
T₅ = 512
Therefore, the 5th term is 512

Take the total number of socks and compare it to the number of yellow socks. 15 and 5. Now divide the total by the specified group (yellow socks), by doing so, you get 3.
Every 1 in 3 socks is yellow, meaning the chance of picking a yellow sock at random is 1/3.
