Answer:
π/2
Step-by-step explanation:
The first peak has an x-coordinate of 0. The second peak has an x-coordinate of π/2. The period is the difference of these:
period = π/2 -0
period = π/2
Given f(x)=−3x−1, solve for x when f(x)=−10.
Answer: X= -3
Step-by-step explanation: If f(x)= 3x-1
then you would do the math 3x-1= -10
which makes out to be x= -3
perimeter of rectangular plot is 36 meters the length is increased by 6meters and breadth is decreased by 3 meters the area of the plot remains the same what is the length of the plot
Perimeter of a rectangular plot = 36 m.
Find:length of the plot
Solution:Let the length of the plot be x and it's breadth be y.
We know that,
Perimeter of a rectangle = 2(length + breadth)
⟹ 2(x + y) = 36
⟹ x + y = 36/2
⟹ x = 18 - y -- equation (1)
Also,
If length is increased by 6 m & breadth is decreased by 3 m , the area remains same.
Area of a rectangle = length * breadth
So,
(x + 6) * (y - 3) = xy
⟹ x(y - 3) + 6(y - 3) = xy
⟹ xy - 3x + 6y - 18 = xy
Substitute the value of x from equation (1).
⟹ - 3(18 - y) + 6y = 18
⟹ - 54 + 3y + 6y = 18
⟹ 9y = 18 + 54
⟹ y = 72/9
⟹ y = 8 m
Substitute the value of y in equation (1).
⟹ x = 18 - 8
⟹ x = 10 m
Hence,
Length (x) = 10 m
Breadth (y) = 8 m.
∴ The length of the plot is 10 m.
I hope it will help you.

Find the vertex of the graph of the quadratic function. Determine whether the graph opens upward or downward, find the y-intercept, and sketch the graph. f(x) = -x- 8x-7
The answer is : (-4, 9)
The given function is:
f(x) = -x^2 - 8x - 7
To find the vertex of the parabola, we need to complete the square as follows:
f(x) = -(x^2 + 8x) - 7
= -(x^2 + 8x + 16) + 16 - 7
= -(x + 4)^2 + 9
Hence, the vertex is (-4, 9).
Since the coefficient of x^2 is negative, the parabola opens downward.
To find the y-intercept, we set x = 0:
f(0) = -0^2 - 8(0) - 7 = -7
Therefore, the y-intercept is (0, -7).
To sketch the graph, we plot the vertex (-4, 9) and the y-intercept (0, -7). Since the parabola opens downward, it will have a maximum value at the vertex. We can also plot a few other points by choosing values of x and calculating the corresponding values of y.
Therefore, the vertex is (-4, 9).

Answer:
x = −1
Step-by-step explanation:
Answer:
x = -1
Step-by-step explanation:
7 - 7 + 16x - 12x - 6 + x = 12x - 13x - 12
Combine like terms
−6 + 5x = -x - 12
Add x to both sides
6x -6 = -12
Add -6 to both sides
6x = -6
Divide 6 to both sides
6x/6 = -6/6
x = -1

Step-by-step explanation:
props to the person that asked the question <3
Option (c) is correct.
The equation of the line is y = 4x -6, when the coordinate system with the y-axis is numbered from negative 6 to 6 in increments of 2 and the x-axis is numbered from negative 4 to 4 in increments of 2.
What is the equation of a line?
A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. On the y-axis, this value c is referred to as the intercept. Key Concept.
Y = mx + c represents the equation of a straight line with gradient m and intercept c on the y-axis.
The given coordinates are:
(x,y) = (0,-6)
(x,y) = (1,-2)
(x,y) = (2,2)
So, when we substitute the values of x and y as given above in the equation: y = 4x -6, we get the same result of x and y.\
Hence, The equation of the line is y = 4x -6, when the coordinate system with the y-axis is numbered from negative 6 to 6 in increments of 2 and the x-axis is numbered from negative 4 to 4 in increments of 2.

Maricella solves for x in the equation 4 x minus 2 (3 x minus 4) + 4 = negative x + 3 (x + 1) + 1. She begins by adding –4 + 4 on the left side of the equation and 1 + 1 on the right side of the equation. Which best explains why Maricella's strategy is incorrect?
Answer:
Step-by-step explanation:
Given the equation
4x-2(3x-4)+4 = -x+3(x+1)+1
Open the parenthesis on both sides
4x-6x+8+4 = -x+3x+3+1
-2x+12 = 2x+4
Collect like terms
-2x-2x = 4-12
-4x = -8
Divide both sides by -4
-4x/-4 = -8/-4
x = 2
Hence the value of x is 2

Give the equation of the line going through the point (0, -3) and perpendicular to 4x - 8y = 16.
Please answer quickly. It's due tomorrow
Answer:
y=-1/4x+3
Step-by-step explanation:
put it into y-y1=m(x-x1) form, which gives you y+3=-1/4x(x+0)
(side note: we change the y- to a y+ becuase the y in the point in negative. another side note, the slope is -1/4x because perpendicular slopes are opposite, in this case 4x (or 4/1x) is the opposite of -1/4 x)
then remove the parenthesis. y+3=-1/4x
then isolate y and balance the equation.
y+3-3=-1/4x-3
this gives you the answer of y=-1/4x-3.
Answer:
y=-2x-3
Step-by-step explanation:
The equation of the line in the slope-intercept form is y=x2−2.
The slope of the perpendicular line is negative inverse: m=−2.
So, the equation of the perpendicular line is y=−2x+a.
To find a, we use the fact that the line should pass through the given point: −3=(−2)⋅(0)+a.
Thus, a=−3.
Therefore, the equation of the line is y=−2x−3.
Answer: y=−2x−3.

Ast week, Shelly rode her bike a total of 30 miles over a three-day period. On the second day, she rode 4 5 the distance she rode on the first day. On the third day, she rode 3 2 the distance she rode on the second day. How many miles did Shelly ride on each day? Select your answers from the drop-down lists. On the first day, Shelly rode miles. On the second day, Shelly rode miles. On the third day, Shelly rode miles.
Answer: On the first day, Shelly rode 10 miles on first day.
On the second day, Shelly rode 8 miles.
On the third day, Shelly rode 12 miles.
Step-by-step explanation:
Let x = distance rod eon first day.
Shelly rode her bike a total of 30 miles over a three-day period.
Then as per given,
Distance rode on second day = [tex]\dfrac45x[/tex]
Distance rode on third day [tex]=\dfrac32\times\text{ Distance rode on second day}[/tex]
[tex]=\dfrac32\times\dfrac45x=\dfrac{6}{5}x[/tex]
Total distance rode = [tex]x+\dfrac45 x+\dfrac65x=30[/tex]
[tex]\Rightarrow\ \dfrac{5x+4x+6x}{5}=30\\\\\Rightarrow\ \dfrac{15x}{5}=30\\\\\Rightarrow\ 3x=30\\\\\Rightarrow\ x=\dfrac{30}{3}\\\\\Rightarrow\ x=10[/tex]
Hence, She rode 10 miles on first day.
Distance rode on second day = [tex]\dfrac45\times10=4\times2=8\text{ miles}[/tex]
Distance rode on third day [tex]=\dfrac{3}{2}\times8=3\times4=12\text{ miles}[/tex]
