How many solutions does the following equation has
Answer:
I think only 1 but not 100% sure
Step-by-step explanation:
Answer:
One solution
Step-by-step explanation:
Combine like terms and simplify.
20z - 5 - 12z = 10z + 8
⇒ z(20 - 12) - 5 = 10z + 8
⇒ z(8) - 5 = 10z + 8
⇒ 8z - 5 = 10z + 8
Subtract 8z both sides.
⇒ 8z - 8z - 5 = 10z + 8 - 8z
⇒ -5 = 2z + 8
Subtract 8 both sides.
⇒ -5 - 8 = 2z + 8 - 8
⇒ -13 = 2z
⇒ -13/2 = 2z/2
⇒ -6.5 = z
Thus, there is 1 solution.

Identify the mistake and write down the correct answe 2/5 + 1/3 = 3/8
Answer:
The mistake is that the denominators are not the same in these fractions so you cannot add them yet. So, you would have to change the denominators to be the same before adding. The denominators I chose is 15, 2/5 times 3 which is equal to 6/15 and 1/3 times 5 which is equal to 5/15. Now, we can add 6/15 and 5/15 which is equal to 11/15!

Based on the function h(t), what will be the account value 5 years after the account is opened?
A.) $5,250
B.) $6,250
C.) $25,250
D.) $26,250
Answer:
B. $6,250
Step-by-step explanation:
Given data
constant function f(t)=5000
linear function g(t)=250t
new function= h(t)=f(t)+g(t)
the new value will be
5000+250t
substituting t = 5 in the linear function we have
=5000+250(5)
=5000+1250
=6250
the answer is $6250

The length of a rectangular parking area is two times the width. The perimeter is 90 ydFind the length and width of the parking area.
Question :-
The Length of a Rectangular Parking Area is Two times the Width. The Perimeter is 90 yards . Find the Length and Width of the Parking Area .Answer :-
Length of Parking Area is 15 yards .Width of Parking Area is 30 yards .Explanation :-
As per the provided information in the given question, we have been given that the Length of a Rectangular Parking Area is Two times the Width . The Perimeter is given as 90 yards . And, we have been asked to calculate the Length and the Width .
Let the Values be like :-
Length = xBreadth = 2xNow, for calculating the Length & Width , we will use the Formula :-
[tex] \bigstar \: \: \boxed{ \sf{ \: Perimeter \: _{Rectangle} \: = \: 2 \times [ \: Length + Breadth \: ] \: }} [/tex]
Therefore , by Substituting the given values in the above Formula :-
[tex] \dag \: \: \: \sf{Perimeter \: _{Rectangle} \: = \: 2 \: \times \: [ \: Length \: + \: Breadth \: ]} [/tex]
[tex] \longmapsto \: \: \: \sf { 90 \: = \: 2 \: \times \: [ \: x \: + \: 2x \: ]} [/tex]
[tex] \longmapsto \: \: \: \sf {90 \: = \: 2 \: \times \: [ \: 3x \: ]} [/tex]
[tex] \longmapsto \: \: \: \sf {90 \: = \: 2 \: \times \: 3x } [/tex]
[tex] \longmapsto \: \: \: \sf {90 \: = \: 6x } [/tex]
[tex] \longmapsto \: \: \: \sf {x \: = \: \dfrac { \: 90 \: }{6}} [/tex]
[tex] \longmapsto \: \: \textbf {\textsf{ x \: = \: 15}} [/tex]
Therefore :-
[tex] \Longrightarrow \: [/tex] Length = x = 15 yards
[tex] \Longrightarrow \: [/tex] Breadth = 2x = 2 × 15 = 30 yards
[tex] \underline {\rule {210pt} {4pt}} [/tex]

Kindly Scroll the Screen from Right to Left for Better View .The Length of Parking Area is 15 yards and the Width of Parking Area is 30 yards .
What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The Perimeter is given as 90 yards. we have been asked to calculate the Length and the Width .
Let the Values be like :-
Length = x
Breadth = 2x
Now, we will use the Formula :-
Perimeter = 2(L + B)
By Substituting the given values in the above Formula :-
Perimeter = 2(L + B)
90= 2(x + 2x)
90= 2(3x)
45 = 3x
x = 15
Therefore :-
Length = x = 15 yards
Breadth = 2x = 2 × 15 = 30 yards

Sum of the interior angles of any triangle equal 180° .
So ;
A + B + ECB = 180°
A = B = μ
So : 2μ + ECB = 180°
→ ECB = 180° - 2μ
_________________________________
ECF + ECB = 180°
ECF + 180° - 2μ = 180°
ECF = 180° - 180° + 2μ
ECF = 2μ
_________________________________
∆ ADE :
A + D + E = 180°
μ + 90° + E = 180°
E = 180° - 90° - μ
E = 90° - μ
_________________________________
AED + AEF = 180°
90° - μ + AEF = 180°
AEF = 180° - 90° + μ
AEF = 90° + μ
_________________________________
AEF + FEC = 180°
90° + μ + FEC = 180°
FEC = 180° - 90° - μ
FEC = 90° - μ (( # ))
_________________________________
∆ BDF :
B + D + F = 180°
μ + 90° + F = 180°
F = 180° - 90° - μ
F = 90° - μ ((★))
_________________________________
((#)), ((★)) say :
FEC = 90° - μ
F = 90° - μ
So : F =~ FEC

2. Consider the line
y = 3/5x -8
What is the
slope of the line perpendicular to this line?
Answer:
The slope of the perpendicular line is [tex]-\frac{5}{3}[/tex]
Step-by-step explanation:
The product of the slopes of the perpendicular lines is -1That means to find the slope of a perpendicular line to a given line, reciprocal its value, and reverse its signEx: If the slope of a line is [tex]\frac{1}{3}[/tex], then the slope of the line perpendicular to it is -3Let us solve the question
∵ The equation of a line is y = [tex]\frac{3}{5}[/tex] x - 8
→ The form of the equation is y = m x + b, where m is the slope
∴ The slope of the line is [tex]\frac{3}{5}[/tex]
→ To find the slope of the line perpendicular to it reciprocal it and
reverse its sign
∵ The reciprocal of [tex]\frac{3}{5}[/tex] is [tex]\frac{5}{3}[/tex]
→ Change its sign from positive to negative
∴ The slope of the perpendicular line is [tex]-\frac{5}{3}[/tex]
What's the exact area and the exact perimeter of square EFGH shown in the coordinate plane?
Using the distance between two points to find the length of the side of the square, it is found that:
The area is of 50 square units.The perimeter is of [tex]20\sqrt{2}[/tex] units.Hence, option A is correct.The distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by:
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
In this problem, the length of the side of the square can be found as the distance between points G and H, that is, the distance between (0,5) and (-5,0), hence:
[tex]l = \sqrt{(0 - (-5))^2 + (5 - 0)^2} = \sqrt{50} = \sqrt{2 \times 25} = 5\sqrt{2}[/tex]
The area of a square of side length l is given by:
[tex]A = l^2[/tex]
Hence:
[tex]A = (5\sqrt{2})^2 = 50[/tex]
The area is of 50 square units.
The perimeter of a square of side length l is given by:
[tex]P = 4l[/tex]
Hence:
[tex]P = 4(5\sqrt{2}) = 20\sqrt{2}[/tex]
The perimeter is of [tex]20\sqrt{2}[/tex] units.

On the graph of f(x)=sinx and the interval [2π,4π), for what value of x does f(x) achieve a minimum?
Answer:
Step-by-step explanation:
The minimum value of sinx is -1 when x = 3π/2, 7π/2, ...
In [2π, 4π), x = 7π/2
The function f(x)=sin(x) achieves its minimum value of -1 at x=3π.
The function f(x)=sin(x) is a periodic function with a period of 2π, meaning it repeats every 2π units. Within the interval [2π,4π), which is one period of the function, the minimum value of sin(x) occurs at x=3π.
This is because at x=3π, the sine function reaches its minimum value of -1. As you move further away from 3π, the sine function starts increasing again.
So, within the interval [2π,4π), the function f(x)=sin(x) achieves its minimum value of -1 at x=3π.

Please teach me how to solve part b, thank you.
Part (a)
The locus is the set of points that satisfy the given conditions. Namely that the point P needs to be 1 unit from the line given.
Think of a median along a highway. Then imagine the two shoulders of the road. The locus describes the two parallel lines that are to this given median. In other words, the median is y = x+2 and the road shoulders are unknown for now.
Though we do know that parallel lines have equal slopes (but different y intercepts).
Therefore, the answers to the next section will be of the form y = x+k for some real number k.
=============================================================
Part (b)
Use your favorite graphing tool to plot y = x+2. I recommend GeoGebra since I use it all the time, and it's what I used to make the drawing below. Desmos is another tool you can use. Both are free.
Note that point A(0,2) is on the line y = x+2. The line perpendicular to y = x+2 and goes through (0,2) is y = -x+2. From here, plot a circle centered at (0,2) with radius 1. The equation of this circle is x^2 + (y-2)^2 = 1
The intersection points of the circle and y = -x+2 will provide starting points, so to speak, for the two shoulder lines I mentioned in part (a).
The approximate locations of those points are:
B = (0.71, 1.29)
C = (-0.71, 2.71)
From here, it shouldn't be too hard to find the y = mx+b forms of the locus lines. Let me know if you need help with that, or if you need me to check your answers.
Side note: Why is it called a locus? I'm not sure, but my gut feeling tells me it has to do with the insects of a similar sounding name (locus the math term and locust the insect). Imagine millions of them forming various shapes in the sky, similar to how many points are used in the 2D plane to create various curves.
