Answer:
A = 1
B = 2
C = 10
Step-by-step explanation:
slope intercept form is
y = mx + b
m is the slope
b is the y-intercept
The slopes of parallel lines are negative reciprocals
------------------------------
y = 2x + 7
slope = 2
slope of perpendicular line is the negative reciprocal of 2
slope = -1/2
y = 5x - 5
y-intercept is -5
-----------------------
slope intercept form of perpendicular line
using slope = -1/2 and y-intercept = -5
y = -(1/2)x - 5
Change to standard form:
multiply both sides by 2
2y = -x - 10
Add x + 10 to both sides
x + 2y + 10 = 0
Therefor
A = 1
B = 2
C = 10
At noon, the temperature at a mountaintop research center is 11 degrees. Overnight the temperature drops to -19 degrees. Which expression represents how much the temperature changed? A. (191 B. |-191 C. |-301 D. |-381
if anyone wants to answer my last 2 questions I would really appreciate
Answer: -30
Step-by-step explanation:
My answer is correct because, All you have to do is subtract all the numbers by 11 and the one that has the sum -19 is the correct choice. In this case -30 does and we can make sure were orrect by subtracting 11 by -19 and that equals -30.

Carlos has a nail in his car tire. The tire is not flat, but he's on his way to get it fixed. He's driving at a constant speed, and the diameter of the tire is 3 feet.
Which rule could model the height of the nail from the ground?
a) f(x)=1.5cos(16πx)+1.5
b) f(x)=1.5cos(16πx)−1.5
c) f(x)=3cos(16πx)+3
d) f(x)=16πcos(1.5x)+3
Answer:
f(x)=1.5cos(16πx)+1.5
(Question on a Quiz was correct)
The trigonometric equation is f ( x ) = 1.5cos ( 16πx ) + 1.5 , when x = 3 feet , the height of the nail from the ground is 3 feet
What are trigonometric relations?Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the trigonometric equation be represented as A
Now , the value of A is
f ( x ) = 1.5cos ( 16πx ) + 1.5
Let the diameter of the tire be x
Let the height of the nail from ground be f ( x )
On simplifying , we get
when x = 3 feet
f ( 3 ) = 1.5 cos ( 16π ( 3 ) ) + 1.5
f ( 3 ) = 1.5 cos ( 48π ) + 1.5
From the trigonometric relation cos ( nπ ) = 1
f ( 3 ) = 1.5 + 1.5 = 3 feet
Hence , the height of the nail from the ground is given by the equation with f ( x ) = 1.5cos ( 16πx ) + 1.5

a. (4, -6)
b. (-4, 6)
c. (-6, -4)
d. (-6, 4)
Answer:
a. (4, -6)
Step-by-step explanation:
When a reflection over the y-axis takes place, the x value will change its sign, while the y value will remain the same. Test this using a graph if needed. Recall that a reflection over the n axis will not change the value of the n coordinate.

Step-by-step explanation:
6). Equation of the line has been given as,
4x + 9y = -9
By converting this equation into y-intercept form,
9y = -4x - 9
[tex]y=-\frac{4}{9}x-\frac{9}{9}[/tex]
[tex]y=-\frac{4}{9}x-1[/tex]
By comparing this equation with y = mx + b
Here, m = Slope of the line
b = y-intercept
Slope of the equation (m) = [tex]-\frac{4}{9}[/tex]
y-intercept (b) = -1
8). Equation of the line is,
5x + 3y = 12
3y = -5x + 12
[tex]y=-\frac{5}{3}x+\frac{12}{3}[/tex]
[tex]y=-\frac{5}{3}x+4[/tex]
Slope of the line = [tex]-\frac{5}{3}[/tex]
y-intercept = 4

If y varies inversely as the square ofx, and y = 1/8 when x = 1, find y when x = 5
Answer:
25/8
Step-by-step explanation:
The question can be interpreted as
Y= k/x^2.......eqn(1)
Where k= constant if proportionality
y = 1/8 when x = 1,
Substitute, we have
1/8= k/(1)^2
1/8= 1/k
Cross multiply
K= 1/8
find y when x = 5
From eqn(1)
Y= k/x^2
Y= (1/8)/(5)^2
Y=1/8 ×25
Y= 25/8
which of the following r-values represents the strongest correlation?
A.-0.61
B.-0.51
C.-0.81
D-0.71
The r-value that represents the strongest correlation is -0.81 (option C). Details about correlation coefficient can be found below.
What is correlation?Correlation coefficient is any of the several measures indicating the strength and direction of a linear relationship between two random variables.
The correlation coefficient is denoted by r. A r-value can either be negative or positive depending on the direction of the relationship.
However, the closer a r-value is to 1, the stronger the relationship. This means that a r-value of -0.81 represents the strongest correlation.

Look at the triangles below. Choose True or False for each of the statements about them.
In triangle ABC angle c = 180-78-40 = 62 degrees
For the triangles to be congruent angle z must equal angle C

2x + 8 = 62
Subtract 8 from both sides:
2x = 54
Divide both sides by 2:
X = 27
Now we k ow x has to equal 27 to be concurrent so we can answer the 3 questions.
