write the general form of the equation of a line that is parallel to the given line and passes through the given point. y+2= -(x+1); (-2,6)
Answer:
y = -x + 4
Step-by-step explanation:
y + 2 = -x - 1
y = - x - 1 - 2
y = -x - 3
Point: (-2,6)
Slope -1

Answer:
w = 63
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 interior angles.
w + 28 is an exterior angle of the triangle , then
w - 2 + w - 33 = w + 28 , that is
2w - 35 = w + 28 ( subtract w from both sides )
w - 35 = 28 ( add 35 to both sides )
w = 63

Write the STANDARD FORM of the equation of each line given the Slope and y-intercept.
1) Slope = 8, y-intercept = 3
2) Slope= -2/3, y-intercept = 1
Answer: See below
Step-by-step explanation:
The basic form of an equation of a straight line in slope intercept form is y=mx+b, where m is the slope and b the y intercept (the value of y when x=0)
1) Slope = 8, y-intercept = 3
y=mx+b: y = bx + 3
2) Slope= -2/3, y-intercept = 1
y=mx+b: y = -(2/3)x + 1

2 trig ratios missing sides and angels
Answer:
D
Step-by-step explanation:
Using the cosine ratio in the right triangle.
cos66° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{13}{x}[/tex] ( multiply both sides by x )
x × cos66° = 13 ( divide both sides by cos66° )
x = [tex]\frac{13}{cos66}[/tex] ≈ 32.0 ( to the nearest tenth )
determine the zeros of the function f(x) = 2(x – 6)^2 – 4
Answer:
x = 6 ± [tex]\sqrt{2}[/tex]
Step-by-step explanation:
To find the zeros equate f(x) to zero , that is
2(x - 6)² - 4 = 0 ( add 4 to both sides )
2(x - 6)² = 4 ( divide both sides by 2 )
(x - 6)² = 2 ( take square root of both sides )
x - 6 = ± [tex]\sqrt{2}[/tex] ( add 6 to both sides )
x = 6 ± [tex]\sqrt{2}[/tex]
The zeros are x = 6 - [tex]\sqrt{2}[/tex] , x = 6 + [tex]\sqrt{2}[/tex]

Valentina's parents are planning a trip to the Typhoon Towers resort. They plan to get a 6-day Fun Pass, which will give Valentina access to all the slides and pools at the resort during their stay. Her parents also plan to get her a $30 arcade pass. Altogether, Valentina's parents will spend $129 on passes. What is the daily cost of a Fun Pass?
Answer:
$16.50
Step-by-step explanation:
Subtract the money $129-$30=$99
$99 divided by 6
The daily cost of the fun pass paid by Valentina's parents is $16.5 per day.
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
Let y represent the total cost for x number of days.
Since they plan to get her a $30 arcade pass, hence b = 30. Also they will spend $129 on passes. y = 129, x = 60. Hence:
129 = m(6) + 30
6m = 99
m = 16.5
Therefore the daily cost of the fun pass is $16.5 per day.

The College Board states that the average math SAT score is 514 with a standard deviation of 117. Colleen gathered data from 50 students in her graduating class and found the average score to be 523. She thinks that her class’s math SAT score is different from the average. Which of the following are the correct null hypothesis and alternate hypothesis? H0: Mu = 514; Ha: Mu greater-than 514 H0: Mu not-equals 514; Ha: Mu = 523 H0: Mu = 514; Ha: Mu not-equals 514 H0: Mu = 514; Ha: Mu = 523.
From the hypothesis test, we have that:
The null hypothesis is [tex]H_0: \mu = 514[/tex].The alternative hypothesis is: [tex]H_1: \mu \neq 514[/tex]At the null hypothesis, it is tested if her average is the same as the national of 514, hence:
[tex]H_0: \mu = 514[/tex]
At the alternative hypothesis, it is tested if it is different, hence:
[tex]H_1: \mu \neq 514[/tex]

Rewrite the limand as
[tex]\dfrac{\tan^2(x)}{1 - \cos(x)} = \dfrac{\sin^2(x)}{\cos^2(x)(1 - \cos(x))}[/tex]
Multiply the numerator and denominator by 1 + cos(x). Then
[tex]\dfrac{\sin^2(x)}{\cos^2(x)(1 - \cos(x))} \cdot \dfrac{1+\cos(x)}{1+\cos(x)} = \dfrac{\sin^2(x)(1 + \cos(x))}{\cos^2(x)(1 - \cos^2(x))} \\\\= \dfrac{\sin^2(x)(1 + \cos(x))}{\cos^2(x)\sin^2(x)} \\\\ = \dfrac{1 + \cos(x)}{\cos^2(x)}[/tex]
As x goes to 0, the limand goes to (1 + 1)/1² = 2.
We are given with a limit :-
[tex]{\quad \blacktriangleright \blacktriangleright \blacktriangleright {\displaystyle \sf \lim_{x\to 0}\dfrac{\tan^{2}(x)}{1-\cos (x)}}}[/tex]
We know that ;
[tex]{\boxed{\bf \dfrac{\sin (\theta)}{\cos (\theta)}=\tan (\theta)}}[/tex]Using this , the above limit can be written as ;
[tex]{:\implies \quad \displaystyle \sf \lim_{x\to 0}\dfrac{\sin^{2}(x)}{\cos^{2}(x)\{1-\cos (x)\}}}[/tex]
Multiplying and dividing both numerator and denominator by [tex]{\sf 1+\cos (x)}[/tex]
[tex]{:\implies \quad \displaystyle \sf \lim_{x\to 0}\dfrac{\sin^{2}(x)\{1+\cos (x)\}}{\cos^{2}(x)\{1-\cos (x)\}\{1+\cos (x)\}}}[/tex]
We knows a identity that is
[tex]{\boxed{\bf a^{2}-b^{2}=(a+b)(a-b)}}[/tex]Using this we have ;
[tex]{:\implies \quad \displaystyle \sf \lim_{x\to 0}\dfrac{\sin^{2}(x)\{1+\cos (x)\}}{\cos^{2}(x)\{1-\cos^{2}(x)\}}}[/tex]
We knows another Trigonometric identity i.e ;
[tex]{\boxed{\bf 1-\cos^{2}(\theta)=\sin^{2}(\theta)}}[/tex]Now , using this we have ;
[tex]{:\implies \quad \displaystyle \sf \lim_{x\to 0}\dfrac{\cancel{\sin^{2}(x)}\{1+\cos (x)\}}{\cos^{2}(x)\cancel{\sin^{2}(x)}}}[/tex]
[tex]{:\implies \quad \displaystyle \sf \lim_{x\to 0}\dfrac{1+\cos (x)}{\cos^{2}(x)}}[/tex]
Putting the limit we have ;
[tex]{:\implies \quad \displaystyle \sf \dfrac{1+\cos (0)}{\cos^{2}(0)}}[/tex]
[tex]{:\implies \quad \displaystyle \sf \dfrac{1+1}{1^{2}} \quad \qquad \{\because \cos (0)=1\}}[/tex]

Billy dove off a cliff into the water. The cliff was 15 ft. above sea level. After diving into the water, he swam 5 ft. below the opposite elevation of the cliff and found a golden ring. At what elevation did he find the golden ring?
Answer:
Billy found the ring at -20 ft
Step-by-step explanation:
He started at 15 ft
He dove off the cliff, then swam 5 feet under the opposite of the cliff's elevation
The opposite of the cliff's elevation would be -15, and if he swam five feet under that, it would be -15 + -5 = -20
So, Billy found the ring at -20 ft
