Find the equation of the line that is parallel to the given line and passes through the given point. y=0,5x-2;(-2,1)
The equation is y=
Answer:
y = 0.5x
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 0.5x - 2 ← is in slope- intercept form
with slope m = 0.5
Parallel lines have equal slopes, thus
y = 0.5x + c ← is the partial equation
To find c substitute (- 2, 1) into the partial equation
- 1 = - 1 + c ⇒ - 1 + 1 = 0
y = 0.5x + 0 , that is
y = 0.5x ← equation of parallel line

The ratio of the measures of the sides of a triangles is 9:7:3. If the perimeter of the triangle is 266 inches, find the value of x
Answer: Depends on which side x is...
Step-by-step explanation:
This is my strategy for finding the values using ratios
Add the ratio together: 9 + 7 + 3 = 19
Divide the perimeter by the sum of the ratio: 266/19 = 14
Now we know what a unit of one is on the ratio: 14
Multiply this unit by the ratio amount
Side with ratio 9: 9 × 14 = 126 inches
Side with ratio 7: 7 × 14 = 98 inches
Side with ratio 3: 3 × 14 = 42 inches

What is a matrix?
A matrix, which is used to represent a mathematical object or an attribute of one, is a rectangular array or table containing numbers, symbols, or expressions that are organized in rows and columns.
The given matrix is,
[tex]\left[\begin{array}{cc}6&-4\\-9&6\\\end{array}\right][/tex]
The determinant of the matrix will be calculated as below:-
D = ( 6 x 6 ) - ( -9 x -4 )
D = ( 36 - 36 )
D = 0
Here the determinant of the matrix is zero. Therefore, the matrix is not invertible.

Bikash got discount of Rs 3000 with 13 percent discount rate to buy a TV set what was the MP of set
Answer:
discount amt. =rs 3000
dis% = 13%
MP = ?
we know,
discount amt. = dis% ×MP
or, 3000 = 13 % × MP
or, 3000 = 13÷ 100 × MP
or, 3000 × 100 = 13 × MP
or, 300000÷ 13 = MP
or, 23076.9 = MP
MP = 23077

(4,0)
Oy-x-1
Oy-1
45
o,-1)
Answer:
the third option is the answer, y= 1/4x-1
Step-by-step explanation:
graph line in standard form:
[tex]y = mx + c[/tex]
where m = slope and c = y-intercept
1) find the slope
slope formula:
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
use the two coordinates given in the graph
i/ (0,-1)
x1 = 0
y1 = -1
ii/ (4,0)
x2 = 4
y2 = 0
substitute the values into the formula
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
[tex] \frac{0 - ( - 1)}{4 - 0} [/tex]
[tex] \frac{1}{4} [/tex]
thus, m = 1/4
2) find the y-intercept
* y-intercept is the value of y that cuts through the y-axis
based on the graph, the y-intercept is -1
thus, c = -1
3) substitute the value of m and c into the standard form formula
[tex]y = mx + c[/tex]
[tex]y = \frac{1}{4} x - 1[/tex]
In ΔNOP, the measure of ∠P=90°, the measure of ∠O=37°, and PN = 72 feet. Find the length of OP to the nearest tenth of a foot.
Answer:
119.6
Step-by-step explanation:
Remark
Draw a rough sketch of what is given.
You will find the NP is the side opposite of the triangle.
P is the right angle
OP is the hypotenuse.
Given
NP = 72
<O = 37
Equation
Sin(O) = NP/OP
Sin(72) = .6018
0.6018 = 72/OP Multiply both sides by OP
0.6018*OP = 72 Divide both sides by 0.6018
OP = 72/0.6018
OP = 119.6

Step-by-step explanation:
The y in the second equation is preceded by a negative coefficient, therefore it will be positive when added to the other side. All the numbers in the equation are even and easily divided by 2 as well. 2 is also the smallest number in the equation, so the remaining numbers will remain whole.

the depth of water at the end of a boat dock can be modeled by a senusoidal function Y=Asin [B(r+C) ]+D where y represents the depth in feet of the water, hours after midnight on a certain day, the depth is 10 feet at low tide at 6 am and 18 feet at high tide at noon find the amplitude and midline for the general sine function that can be used to model the water's depth.
Answer:
A=4 ft
Midline: y=14
Step-by-step explanation:
When talking about sinusoidal waves, we know the amplitude will be the distance between the midline and the highest or lowest point of the graph. This can be found by first, finding the distance between the lowest point and the highest point:
d= 18ft - 10ft = 8ft
and divide this distance into 2:
[tex]A=\frac{8}{2}[/tex]
A= 4 ft
in order to find the midline, we need to figure the midpoint between the highest and lowest value. We can do so by using the following formula:
[tex]Midpoint=\frac{high+low}{2}[/tex]
so:
[tex]Midpoint=\frac{18+10}{2}[/tex]
Midpoint = 14
so the midline is located at the line:
y=14
