Find the perimeter of the semicircle. Let ≈ 3.14. r=17
Answer:
53.38
Step-by-step explanation:
First, find the circumference of the whole circle.
C=2pir
C=2(3.14)(17)
C=106.76
Then, divide by 2 because a semi-circle is half of a circle.
106.76/2 = 53.38
Therefore, the circumference, or the perimeter, of the semicircle is 53.38

B.
He needs to show only that the diagonals are perpendicular and congruent.
C.
He needs to show only that the diagonals are perpendicular and bisect each other.
D.
He needs to show that the diagonals are perpendicular, congruent, and bisect each other.
Answer: D
Step-by-step explanation:
You need to prove that the diagonals bisect each other to prove it's a parallelogram.
Now, to prove it's a square, you need to prove it's both a rectangle and a rhombus.
To prove it's a rectangle, you need to prove the diagonals are congruent.To prove it's a rhombus, you need to prove the diagonals are perpendicular.Please answer quick 15 points this is urgent

7. The cost price of a book is $8. Find the selling price of the
book if the store's markup is 36%.
Answer:
$10.88
Step-by-step explanation:
To find the selling price, we first have to find the markup price by multiplying 8 by 36 and then dividing the product by 100.
8 × 36 = 288288 ÷ 100 = 2.88Now, we add the markup price the cost of the book.
2.88 + 8 = $10.88.Therefore, the selling price is $10.88.

Answer:
4) 14.5
6) 11.4
Step-by-step explanation:
4) Area = 20 * 21/2 = 29 * x/2
so x = 20 * 21/29 = 14.5
6) Area = 22.4 * 13.2/2 = 26 * x/2
so x = 22.4 * 13.2/26 = 11.4
Which graph represents the function y = log x + 4?
Answer:
see attached
Step-by-step explanation:
We assume you are looking for the graph of ...
y = log(x) +4
This represents a vertical translation 4 units upward of the graph of log(x). That is, the point (1, 0) that appears on a graph of a log function will be translated to (1, 4).
The only graph shown that goes through the point (1, 4) is the last one, attached.
__
If you are actually looking for the graph of ...
y = log(x +4)
it will be a graph of the log function shifted 4 units to the left. The 2nd offered choice is that graph. The point (-3, 0) will be on that graph.
_____
Additional comment
For a function y = f(x), the transformation ...
y = f(x -h) +k
represents a horizontal shift of h units to the right, and a vertical shift of k units upward. Here, the argument of the log function is not clearly shown, so we cannot tell if the intended shift is to the left or upward.

Explain how the Multiplication Property of Equality can be used to solve the equation
x ÷ 6 = 7.
Step-by-step explanation:
Multiplication property of equality is when you multiply the same number on both sides of an equation, the equation will still hold true.
In order to have x by itself, you need to multiply by 6. The property states that you can multiply 6 on both sides and the equation will still hold true.

A diver is standing on a platform 24 ft above a pool. He jumps from the platform with an initial
upward velocity of 8 ft/s. Using the formula, h(t) = -16t2 + vt + s, where h is his height
above the water, t is the time, v is his starting upward velocity, and s is his starting height.
A) After how long will the diver reach its maximum height?
B) What is the maximum height the diver will reach?
Answer:
A) t = 0.25 s
B) h = 25 m
Step-by-step explanation:
Given equation: [tex]h(t) = -16t^2 + vt + s[/tex]
where:
h = height above water (in feet)t = time (in seconds)v = initial upwards velocity = 8 ft/ss = initial height = 24 ftA) To find the value of t when h is at its maximum, differentiate the equation with respect to t:
[tex]\implies h'(t)=-32t+v[/tex]
Substitute given value of v:
[tex]\implies h'(t)=-32t+8[/tex]
Set to zero and solve for t:
[tex]\implies -32t+8=0[/tex]
[tex]\implies t=0.25 \textsf{s}[/tex]
B) Substitute the found value for t into the equation and solve for h:
[tex]\implies h(0.25) = -16(0.25)^2 + 8(0.25) + 24[/tex]
[tex]\implies h(0.25) = -1 + 2 + 24[/tex]
[tex]\implies h(0.25) =25 \textsf{ m}[/tex]

[1] Both 1 and 2 are equal to 70°
Angle 1 and Angle 2 will be equal to each other because they are vertical angles.
A straight line is 180°, so 180° - 110° = 70°
[2] Both 3 and 4 are equal to 99°
Again, Angle 3 and Angle 4 will be equal to each other because they are vertical angles.
We can solve for the other two angles by putting them equal to each other since they are also vertical angles.
3x - 15° = 2x + 17°
3x = 2x + 32°
x = 32°
-
2x + 17°
2(32)° + 17°
64° + 17°
81°
Also again, a straight line is 180°. 180° - 81° = 99°
[3] This one has too many subparts for Brainly.
As a hint, you will use the same methods above. Find vertical angles and use the degree of a straight line.
Area + circumference of circle
Answer:
153.86 cm² and 43.96
Step-by-step explanation:
The formula to find the area of a circle is A = πr²
A = 3.14(7)²
A = 3.14(49)
A = 153.86
To find the circumference, use the formula C = π2r
C = 3.14*2*7
C = 43.96
The area of the circle is 153.86 cm² and the circumference of the circle is 43.96.
Hope this helps :)
In a survey of 2500 registered voters, 1900 of them said that they plan to vote in the next presidential election. Let p denote the proportion of all registered voters who plan to vote. Find the 95% confidence interval for p.
This can alternatively be written as 0.74 < p < 0.78
========================================================
Explanation:
n = 2500 = sample size
x = 1900 = number of successes = number who plan to vote
phat = x/n = 1900/2500 = 0.76
phat is the sample proportion that estimates the population proportion p.
At 95% confidence, the z critical value is roughly z = 1.96 which you use a table or calculator to find this value (or it's something you memorize).
E = margin of error
E = z*sqrt(phat*(1-phat)/n)
E = 1.96*sqrt(0.76*(1-0.76)/2500)
E = 0.016742 approximately
The lower bound (L) of the confidence interval is
L = phat - E
L = 0.76 - 0.016742
L = 0.743258
L = 0.74
The upper bound (U) of the confidence interval is
U = phat + E
U = 0.76 + 0.016742
U = 0.776742
U = 0.78
The values of L and U are approximate.
The confidence interval in the format (L, U) would be (0.74, 0.78) approximately.
Another way to write the confidence interval is to say 0.74 < p < 0.78 as it's in the form L < p < U; showing that we're 95% confident that p is somewhere between 0.74 and 0.78
In other words, we're 95% confident that between 74% and 78% of the population would plan to vote in the next presidential election.
