BC = 17.1
Angle B = 6.7°
Angle C = 83.3°
To find side BC, you use pythagorean’s theorem, which is a^2 + b^2 = c^2
This gives you 289 + 4 = 293, and you find the square root, which is 17.1.
To find the angle measures you can use tangent, which is opposite sides over adjacent sides. You plug these values into a calculator.
b = tan 2/17 = 6.7°
c = tan 17/2 = 83.3°
Answer:
BC = 17.1
m<B = 6.7 deg
m<C = 83.3 deg
Step-by-step explanation:
Find BC
a^2 + b^2 = c^2
AC^2 + AB^2 = BC^2
2^2 + 17^2 = BC^2
4 + 289 = BC^2
BC^2 = 293
BC = sqrt(293)
BC = 17.1
Find <B
tan B = opp/adj
tan B = 2/17
B = tan^-1 2/17
B = 6.7 deg
Find <C
m<A + m<B + m<C = 180
90 + 6.7 + m<C = 180
m<C = 180 - 90 - 6.7
m<C = 83.3

What is the equation of a circle with center (7, 2) and radius 2?
Answers
Answer:
(x - 7)² + (y - 2)² = 4
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k ) = (7, 2 ) and r = 2 , then
(x - 7)² + (y - 2)² = 2² , that is
(x - 7)² + (y - 2)² = 4 ← equation of circle

Solve for all solutions of p.
Answers
We are given the equation below:
[tex] \large{ {p}^{2} = \frac{9}{36} }[/tex]
Use the property below:
[tex] \large \boxed{ {x}^{2} = \frac{a}{b} \longrightarrow x = \pm \frac{ \sqrt{a} }{ \sqrt{b} } \: \: (a \geqslant 0 \: \: and \: \: b > 0)}[/tex]
From the equation:
[tex] \large{p = \pm \frac{ \sqrt{9} }{ \sqrt{36} } } \\ \large{p = \pm \frac{3}{6} \longrightarrow p = \pm \frac{1}{2} }[/tex]
Hence the answer is p = ± 1/2.
Answer
p = 1/2, -1/2p = ± 1/2Both answers work. The second answer is in the plus-minus form.

Consultant plans a survey to determine what % of the patients in a particular hospital were satisfied with the care they received after a major treatment. How many such patients should be surveyed so the margin of error for a 90% confidence interval is within .05? Suppose it is known from a past survey that such a % may be about 80%.
Answers
Solution:
Required margin of error = 0.05
Estimated population proportion p = 0.8
Significance level = 0.10
The [tex]\text{provided estimate population proportion}[/tex] p is 0.8
The significance level, α = 0.1 is [tex]z_c=1.645[/tex], which is obtained by looking into a standard normal probability table.
The number of patients surveyed to estimate the population proportion p within the required margin of error :
[tex]$n \geq p(1-p)\left(\frac{z_c}{E}\right)^2$[/tex]
[tex]$=0.8\times (1-0.8)\left(\frac{1.64}{0.05}\right)^2$[/tex]
= 173.15
Therefore, the number of patients surveyed to satisfy the condition is n ≥ 173.15 and it must be an integer number.
Thus we conclude that the number of patients surveyed so the margin of error of 90% confidence interval is within 0.05 are n= 174.

1. Write down an equation in x and y
2. Simplify your equation
3.Find y when x=65°
Answers
Answer:
Step-by-step explanation:
The degrees around a point = 360, so
1. x + 95 + 3y + 80 = 360 so
2. x + 3y = 185
3. 65 + 3y = 185 and
3y = 120 so
y = 40
Answer:
y=40
Step-by-step explanation:
sum of all 3 angles : 240
3y+240=360
3y=360-240=120
y=3÷120
y=40
