Answer:
43°
Step-by-step explanation:
In circle with center P, AB is diameter. Hence, [tex] \widehat{ACB} [/tex] is a semicircular arc.
[tex] \therefore \widehat{ACB}= 180\degree.... (1)\\
\because \widehat{ACB}= \widehat{AD} + \widehat{DC}+ \widehat{CB}.... (2)\\
From\: (1)\: \&\: (2)\\
\widehat{AD} + \widehat{DC}+ \widehat{CB} = 180\degree \\
\therefore (7x + 1)\degree + 90\degree + (9x-7)\degree = 180\degree \\
\therefore (16x - 6)\degree = 180\degree- 90\degree\\
\therefore (16x - 6)\degree = 90\degree\\
\therefore 16x - 6 = 90\\
\therefore 16x = 90 +6\\
\therefore 16x = 96\\\\
\therefore x = \frac{96}{16}\\\\
\huge \red {\boxed {\therefore x = 6}} \\
\therefore \widehat{AD} = (7x+1)\degree \\
\therefore \widehat{AD} = (7\times 6+1)\degree \\
\therefore \widehat{AD} = (42+1)\degree \\
\huge \orange {\boxed {\therefore \widehat{AD} = 43\degree}} \\

Someone help meeee lollll
Answers
Answer:
Step-by-step explanation:
The best way to do this is to first remove the parenthesis by distributing the negative into them. Then we will group the like terms together, moving their respective signs with them, then we will simplify. For the first one, after distributing the negative into the parenthesis (remember that a negative in front of a set of parenthesis containing a polynomial changes the signs in front of each term within the polynomial; negatives become positives and positives become negatives):
[tex]3x^2-6x+11-10x^2+4x-6[/tex] and then grouping like terms next to each other:
[tex]3x^2-10x^2-6x+4x+11-6[/tex] (this step is not completely necessary; I just encourage new learners to do it so as to not miss any of the like terms)
The above then simplifies to
[tex]-7x^2-2x+5[/tex]
The next one, after distributing the negative into the parenthesis:
[tex]-3x^2-5x-3+10x^2+7x-2[/tex] and then grouping like terms next to each other (remember to move their signs with them!):
[tex]-3x^2+10x^2-5x+7x-3-2[/tex] which simplifies to
[tex]7x^2+2x-5[/tex]
Now for the last one:
[tex]12x^2+6x-5-5x^2-8x+12[/tex] and
[tex]12x^2-5x^2+6x-8x-5+12[/tex] which simplifies to
[tex]7x^2-2x+7[/tex]

What is the following product?
Answers
Answer & Step-by-step explanation:
(5√2 - 4√3)(5√2 - 4√3)
We can rewrite this equation into a more simpler form.
(5√2 - 4√3)²
Now, we multiply. When multiplying, its important we multiply each term instead of combining them together.
When you multiply a radical by itself, then the base number will be by itself as the product.
So......
(5)² = 25
(4)² = 16
(√2)² = 2
(√3)² = 3
So, now the equation looks like this..
(25 * 2) + (16 * 3)
Multiply the terms.
50 + 48
Add the numbers.
50 + 48 = 98
So, your answer will be answer choice D. The radical in choice D represents the radicals that are in the problem multiplied together.

Yun wants to build a one-sample z interval with 82%, percent confidence to estimate what proportion of users will click an advertisement that appears on his website. He takes a random sample of 200 users and finds that 34 of them clicked the advertisement.
Answers
Answer:
Step-by-step explanation:
Confidence interval is written as
Sample proportion ± margin of error
Margin of error = z × √pq/n
Where
z represents the z score corresponding to the confidence level
p = sample proportion. It also means probability of success
q = probability of failure
q = 1 - p
p = x/n
Where
n represents the number of samples
x represents the number of success
From the information given,
n = 200
x = 34
p = 34/200 = 0.17
q = 1 - 0.17 = 0.83
To determine the z score, we subtract the confidence level from 100% to get α
α = 1 - 0.82 = 0.18
α/2 = 0.18/2 = 0.09
This is the area in each tail. Since we want the area in the middle, it becomes
1 - 0.09 = 0.91
The z score corresponding to the area on the z table is 1.35. Thus, the z score for a confidence level of 82% is 1.35
Therefore, the 82% confidence interval is
0.17 ± 1.35√(0.17)(0.83)/200
Confidence interval is 0.17 ± 0.036

z ∗ = 1.341

Answers
Answer:
x ≥ 2
Step-by-step explanation:
21 ≤ 3 + 9x
21 - 3 ≤ 9x
18 ≤ 9x
18 ÷ 9 ≤ x
2 ≤ x
x ≥ 2
The solution to the inequality 21 ≤ 3 + 9x by combining like terms and solving for x is, x ≥ 2.
Used the concept of inequality which states that,
A relation by which we can compare two or more mathematical expressions is called an inequality.
Given that,
The inequality is,
21 ≤ 3 + 9x
Now, simplify the inequality by combining like terms and solving for x,
21 ≤ 3 + 9x
Subtract 3 on both sides,
21 - 3 ≤ 9x
18 ≤ 9x
It can be written as,
9x ≥ 18
9x - 18 ≥ 0
Take 9 as common,
9 (x - 2) ≥ 0
x - 2 ≥ 0
Therefore, the solution of expression is,
